I have a remote function testdwr, which returns a list of objects(test). How should i parse the list of objects in the handler method? Code shown below
public List testdwr(String message) {
Test test = new Test();
test.setName("mahati");
List arrayList = new ArrayList();
arrayList.add(test);
return arrayList;
}
handler method:
function update()
{ findaccounts.testdwr("somestring : ",function(data){
alert(data); }
the alert box gives the output as "object Object"!!
The ArrayList returned from the server will looks like,
[Object { name="Mahati"}, Object { name="meena"}, Object { name="keerthi" }.....]
You can have a loop like this,
for(var i=0; i<arrayList.length; i++)
{
var testObj = arrayList[i];
//Here, you can do what you want! like...
alert(testObj.name);
alert(testObj.age);
}
Like Blake said, try to use FireBug, its an addon for firefox.
You should be able to do something like data[0].name
Using alert(data.length) show show 1.
Have you tried using Firebug on Firefox. It allows you to set a break point in the javascript code and examin the variables.

As part of Selenium Web-driver learning I came across a scenario. Please let me know the professional approach to proceed.
I am testing a eCommerce application where while I click on Mobile link all mobile phones are getting displayed.I want to check whether they are sorted based on name and price. So basically I need to get Name & price of all elements in the result page.
So My Question is there any way I can map html elements to java value objects ? Any API already available for doing this mapping for me ? Something similar to gson api for converting java objects to their corresponding Json representation ?
Deepu Nair
//Get all the mobile phones links into a list before sorting
List<WebElement> mobilelinks=driver.findElements(("locator"));
Map maps = new LinkedHashMap();//use linked hash map as it preserves the insertion order
for(int i=0;i<mobilelinks.size();i++){
//store the name and price as key value pair in map
maps.put("mobilelinks.get(i).getAttribute('name')","mobilelinks.get(i).getAttribute('price')" );
}
/*sort the map based on keys(names) store it in a separate list
sort the map based on values(prices) store it in a separate list
*/
/* Using webdriver click the sort by name and compare it with the list which we got after sorting
and also click sort by prices and compare it with the list*/
To catch an assertion and continue with the test after assertion failures override the Assertion class and create your own CustomAssertion or use SoftAssertions
CustomAssertion.java
public class CustomAssertions extends Assertion {
private Map<AssertionError, IAssert> m_errors = Maps.newLinkedHashMap();
#Override
public void executeAssert(IAssert a) {
try {
a.doAssert();
} catch(AssertionError ex) {
onAssertFailure(a, ex);
System.out.println(a.getActual());
System.out.println(ex.getMessage());
m_errors.put(ex, a);
}
}
public void assertAll() {
if (! m_errors.isEmpty()) {
StringBuilder sb = new StringBuilder("The following asserts failed:\n");
boolean first = true;
for (Map.Entry<AssertionError, IAssert> ae : m_errors.entrySet()) {
if (first) {
first = false;
} else {
sb.append(", ");
}
sb.append(ae.getKey().getMessage());
}
throw new AssertionError(sb.toString());
}
}
}
Instead of using Assertions class to verify the tests use CustomAssertions class
Ex:
//create an object of CustomAssertions class
CustomAssertions custom_assert=new CustomAssertions();
cust_assert.assertTrue(2<1);
cust_assert.assertEquals("test", "testing");
//and finally after finishing the test in aftersuite method call
cust_assert.assertAll();
Hope this helps you if you have any doubts kindly get back...
I would like to pass a complete JSON object to a java adapter in worklight. This adapter will call multiple other remote resources to fulfill the request. I would like to pass the json structure instead of listing out all of the parameters for a number of reasons. Invoking the worklight procedure works well. I pass the following as the parameter:
{ "parm1": 1, "parm2" : "hello" }
Which the tool is fine with. When it calls my java code, I see a object type of JSObjectConverter$1 being passed. In java debug, I can see the values in the object, but I do not see any documentation on how to do this. If memory serves me, the $1 says that it is an anonymous inner class that is being passed. Is there a better way to pass a json object/structure in adapters?
Lets assume you have this in adapter code
function test(){
var jsonObject = { "param1": 1, "param2" : "hello" };
var param2value = com.mycode.MyClass.parseJsonObject(jsonObject);
return {
result: param2value
};
}
Doesn't really matter where you're getting jsonObject from, it may come as a param from client. Worklight uses Rhino JS engine, therefore com.mycode.MyClass.parseJsonObject() function will get jsonObject as a org.mozilla.javascript.NativeObject. You can easily get obj properties like this
package com.mycode;
import org.mozilla.javascript.NativeObject;
public class MyClass {
public static String parseJsonObject(NativeObject obj){
String param2 = (String) NativeObject.getProperty(obj, "param2");
return param2;
}
}
To better explain what I'm doing here, I wanted to be able to pass a javascript object into an adapter and have it return an updated javascript object. Looks like there are two ways. The first it what I answered above a few days ago with serializing and unserializing the javascript object. The other is using the ScriptableObject class. What I wanted in the end was to use the adapter framework as described to pass in the javascript object. In doing so, this is what the Adapter JS-impl code looks like:
function add2(a) {
return {
result: com.ibm.us.roberso.Calculator.add2(a)
};
The javascript code in the client application calling the above adapter. Note that I have a function to test passing the javascript object as a parameter to the adapter framework. See the invocationData.parameters below:
function runAdapterCode2() {
// x+y=z
var jsonObject = { "x": 1, "y" : 2, "z" : "?" };
var invocationData = {
adapter : "CalculatorAdapter",
procedure : 'add2',
parameters : [jsonObject]
};
var options = {
onSuccess : success2,
onFailure : failure,
invocationContext : { 'action' : 'add2 test' }
};
WL.Client.invokeProcedure(invocationData, options);
}
In runAdapterCode2(), the javascript object is passed as you would pass any parameter into the adapter. When worklight tries to execute the java method it will look for a method signature of either taking an Object or ScriptableObject (not a NativeObject). I used the java reflection api to verify the class and hierarchy being passed in. Using the static methods on ScriptableObject you can query and modify the value in the object. At the end of the method, you can have it return a Scriptable object. Doing this will give you a javascript object back in the invocationResults.result field. Below is the java code supporting this. Please note that a good chunk of the code is there as part of the investigation on what object type is really being passed. At the bottom of the method are the few lines really needed to work with the javascript object.
#SuppressWarnings({ "unused", "rawtypes" })
public static ScriptableObject add2(ScriptableObject obj) {
// code to determine object class being passed in and its heirarchy
String result = "";
Class objClass = obj.getClass();
result = "objClass = " + objClass.getName() + "\r\n";
result += "implements=";
Class[] interfaces = objClass.getInterfaces();
for (Class classInterface : interfaces) {
result += " " + classInterface.getName() ;
}
result += "\r\nsuperclasses=";
Class superClass = objClass.getSuperclass();
while(superClass != null) {
result += " " + superClass.getName();
superClass = superClass.getSuperclass();
}
// actual code working with the javascript object
String a = (String) ScriptableObject.getProperty((ScriptableObject)obj, "z");
ScriptableObject.putProperty((ScriptableObject)obj, "z", new Long(3));
return obj;
}
Note that for javascript object, a numeric value is a Long and not int. Strings are still Strings.
Summary
There are two ways to pass in a javascript object that I've found so far.
Convert to a string in javascript, pass string to java, and have it reconstitute into a JSONObject.
Pass the javascript object and use the ScriptableObject classes to manipulate on the java side.
I'm trying to sort a Documents Collection using a java.util.ArrayList.
var myarraylist:java.util.ArrayList = new java.util.ArrayList()
var doc:NotesDocument = docs.getFirstDocument();
while (doc != null) {
myarraylist.add(doc)
doc = docs.getNextDocument(doc);
}
The reason I'm trying with ArrayList and not with TreeMaps or HashMaps is because the field I need for sorting is not unique; which is a limitation for those two objects (I can't create my own key).
The problem I'm facing is calling CustomComparator:
Here how I'm trying to sort my arraylist:
java.util.Collections.sort(myarraylist, new CustomComparator());
Here my class:
import java.util.Comparator;
import lotus.notes.NotesException;
public class CustomComparator implements Comparator<lotus.notes.Document>{
public int compare(lotus.notes.Document doc1, lotus.notes.Document doc2) {
try {
System.out.println("Here");
System.out.println(doc1.getItemValueString("Form"));
return doc1.getItemValueString("Ranking").compareTo(doc2.getItemValueString("Ranking"));
} catch (NotesException e) {
e.printStackTrace();
}
return 0;
}
}
Error:
Script interpreter error, line=44, col=23: Error calling method
'sort(java.util.ArrayList, com.myjavacode.CustomComparator)' on java
class 'java.util.Collections'
Any help will be appreciated.
I tried to run your SSJS code in a try-catch block, printing the error in exception in catch block and I got the following message - java.lang.ClassCastException: lotus.domino.local.Document incompatible with lotus.notes.Document
I think you have got incorrect fully qualified class names of Document and NotesException. They should be lotus.domino.Document and lotus.domino.NotesException respectively.
Here the SSJS from RepeatControl:
var docs:NotesDocumentCollection = database.search(query, null, 0);
var myarraylist:java.util.ArrayList = new java.util.ArrayList()
var doc:NotesDocument = docs.getFirstDocument();
while (doc != null) {
myarraylist.add(doc)
doc = docs.getNextDocument(doc);
}
java.util.Collections.sort(myarraylist, new com.mycode.CustomComparator());
return myarraylist;
Here my class:
package com.mycode;
import java.util.Comparator;
public class CustomComparator implements Comparator<lotus.domino.Document>{
public int compare(lotus.domino.Document doc1, lotus.domino.Document doc2) {
try {
// Numeric comparison
Double num1 = doc1.getItemValueDouble("Ranking");
Double num2 = doc2.getItemValueDouble("Ranking");
return num1.compareTo(num2);
// String comparison
// return doc1.getItemValueString("Description").compareTo(doc2.getItemValueString("Description"));
} catch (lotus.domino.NotesException e) {
e.printStackTrace();
}
return 0;
}
}
Not that this answer is necessarily the best practice for you, but the last time I tried to do the same thing, I realized I could instead grab the documents as a NotesViewEntryCollection, via SSJS:
var col:NotesViewEntryCollection = database.getView("myView").getAllEntriesByKey(mtgUnidVal)
instead of a NotesDocumentCollection. I just ran through each entry, grabbed the UNIDs for those that met my criteria, added to a java.util.ArrayList(), then sent onward to its destination. I was already sorting the documents for display elsewhere, using a categorized column by parent UNID, so this is probably what I should have done first; still on leading edge of the XPages/Notes learning curve, so every day brings something new.
Again, if your collection is not equatable to a piece of a Notes View, sorry, but for those with an available simple approach, KISS. I remind myself frequently.
I have a Document class that loads variables from Facebook with the use of stage.loaderInfo
var connect:FacebookConnectObject = new FacebookConnectObject( facebook, API_KEY, this.stage.loaderInfo );
But when I change the Document class (with another one responsible for the layout of my app), and try call the above from a movieclip that exists in my application with the use:
var facebook_class:FacebookAp = new FaceBppkApp
addChild(facebook_class) I get error
TypeError: Error #1009: Cannot access a property or method of a null object reference.
I believe the error comes fro this line
this.stage.loaderInfo
since I changed the scope...
How I am supposed to fix that?
According to a post by Devonair: Seems 99 times out of a 100 when people have a problem with a 1009 error, it's because the stage property is inaccessible.
so I used this snippet
public function start() {
if
{(stage) init();}
else
{ addEventListener(Event.ADDED_TO_STAGE, init);
}
}
private function init(event:Event = null):void {
removeEventListener(Event.ADDED_TO_STAGE, init);
// everything else...
}
In case sb has the same problem...
I am having a minor problem with WCF service proxies where the message contains List<string> as a parameter.
I am using the 'Add Service reference' in Visual Studio to generate a reference to my service.
// portion of my web service message
public List<SubscribeInfo> Subscribe { get; set; }
public List<string> Unsubscribe { get; set; }
These are the generated properties on my MsgIn for one of my web methods.
You can see it used ArrayOfString when I am using List<string>, and the other takes List<SubscribeInfo> - which matches my original C# object above.
[System.Runtime.Serialization.DataMemberAttribute(EmitDefaultValue=false)]
public System.Collections.Generic.List<DataAccess.MailingListWSReference.SubscribeInfo> Subscribe {
get {
return this.SubscribeField;
}
set {
if ((object.ReferenceEquals(this.SubscribeField, value) != true)) {
this.SubscribeField = value;
this.RaisePropertyChanged("Subscribe");
}
}
}
[System.Runtime.Serialization.DataMemberAttribute(EmitDefaultValue=false)]
publicDataAccess.MailingListWSReference.ArrayOfString Unsubscribe {
get {
return this.UnsubscribeField;
}
set {
if ((object.ReferenceEquals(this.UnsubscribeField, value) != true)) {
this.UnsubscribeField = value;
this.RaisePropertyChanged("Unsubscribe");
}
}
}
The ArrayOfString class generated looks like this. This is a class generated in my code - its not a .NET class. It actually generated me a class that inherits from List, but didn't have the 'decency' to create me any constructors.
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "3.0.0.0")]
[System.Runtime.Serialization.CollectionDataContractAttribute(Name="ArrayOfString", Namespace="http://www.example.com/", ItemName="string")]
[System.SerializableAttribute()]
public class ArrayOfString : System.Collections.Generic.List<string> {
}
The problem is that I often create my message like this :
client.UpdateMailingList(new UpdateMailingListMsgIn()
{
Email = model.Email,
Name = model.Name,
Source = Request.Url.ToString(),
Subscribe = subscribeTo.ToList(),
Unsubscribe = unsubscribeFrom.ToList()
});
I really like the clean look this gives me.
Now for the actual problem :
I cant assign a List<string> to the Unsubscribe property which is an ArrayOfString - even though it inherits from List. In fact I cant seem to find ANY way to assign it without extra statements.
I've tried the following :
new ArrayOfString(unsubscribeFrom.ToList()) - this constructor doesn't exist :-(
changing the type of the array used by the code generator - doesn't work - it always gives me ArrayOfString (!?)
try to cast List<string> to ArrayOfString - fails with 'unable to cast', even though it compiles just fine
create new ArrayOfString() and then AddRange(unsubscribeFrom.ToList()) - works, but I cant do it all in one statement
create a conversion function ToArrayOfString(List<string>), which works but isn't as clean as I want.
Its only doing this for string, which is annoying.
Am i missing something? Is there a way to tell it not to generate ArrayOfString - or some other trick to assign it ?
Any .NET object that implements a method named "Add" can be initialized just like arrays or dictionaries.
As ArrayOfString does implement an "Add" method, you can initialize it like this:
var a = new ArrayOfString { "string one", "string two" };
But, if you really want to initialize it based on another collection, you can write a extension method for that:
public static class U
{
public static T To<T>(this IEnumerable<string> strings)
where T : IList<string>, new()
{
var newList = new T();
foreach (var s in strings)
newList.Add(s);
return newList;
}
}
Usage:
client.UpdateMailingList(new UpdateMailingListMsgIn()
{
Email = model.Email,
Name = model.Name,
Source = Request.Url.ToString(),
Subscribe = subscribeTo.ToList(),
Unsubscribe = unsubscribeFrom.To<ArrayOfString>()
});
I prefer not to return generic types across a service boundary in the first place. Instead return Unsubscribe as a string[], and SubscriptionInfo as SubscriptionInfo[]. If necessary, an array can easily be converted to a generic list on the client, as follows:
Unsubscribe = new List<string>(unsubscribeFrom);
Subscribe = new List<SubscriptionInfo>(subscribeTo);
Too late but can help people in the future...
Use the svcutil and explicitly inform the command line util that you want the proxy class to be serialized by the XmlSerializer and not the DataContractSerializer (default). Here's the sample:
svcutil /out:c:\Path\Proxy.cs /config:c:\Path\Proxy.config /async /serializer:XmlSerializer /namespace:*,YourNamespace http://www.domain.com/service/serviceURL.asmx
Note that the web service is an ASP.NET web service ok?!
If you are using VS 2008 to consume service then there is an easy solution.
Click on the "Advanced..." button on the proxy dialog that is displayed when you add a Service Reference. In the Collection Type drop down you can select System.Generic.List. The methods returning List should now work properly.
(Hope this is what you were asking for, I'm a little tired and the question was a tad difficult for me to read.)
