I recently upgraded to activejdbc 1.4.12 and I'm noticing a different behavior when updating a record with empty values.
Please check example below:
public void createClient()
{
// create new client
Client client = new Client();
client.setName("test 1");
client.setAddress("address 1");
client.save();
System.out.println("Client id: " + client.getId()); // prints Client id: 10
}
public void updateClient()
{
// update client information
Client client = new Client();
client.setId(10);
client.setName("test 2");
client.save() ;
}
Then, calling System.out.println("Client address: " + client.getAddress()); I get the following results:
With activejdbc 1.4.9 -> null
With activejdbc 1.4.12 -> "address 1"
Apparently, starting in version 1.4.12, the address will only be updated with null if I explicitely call set(address, null). Anyone else having this issue? Is this correct?

I am loading data from mysql into Ignite cache with following code. The code is run with client mode Ignite and will load the data into Ignite cluster.
I would ask:
Which parts of the code will run at the server side?
The working mechanism of loading data into cache looks like map-reduce, so, what tasks are sent to the server? the sql?
I would particularlly ask: will the following code run at the client side or the server sdie?
CacheConfiguration cfg = StudentCacheConfig.cache("StudentCache", storeFactory);
IgniteCache cache = ignite.getOrCreateCache(cfg);
Following is the full code that loads the data into cache
public class LoadStudentIntoCache {
public static void main(String[] args) {
Ignition.setClientMode(false);
String configPath = "default-config.xml";
Ignite ignite = Ignition.start(configPath);
CacheJdbcPojoStoreFactory storeFactory = new CacheJdbcPojoStoreFactory<Integer, Student>();
storeFactory.setDialect(new MySQLDialect());
IDataSourceFactory factory = new MySqlDataSourceFactory();
storeFactory.setDataSourceFactory(new Factory<DataSource>() {
public DataSource create() {
try {
DataSource dataSource = factory.createDataSource();
return dataSource;
} catch (Exception e) {
return null;
}
}
});
//
CacheConfiguration<Integer, Student> cfg = StudentCacheConfig.cache("StudentCache", storeFactory);
IgniteCache<Integer, Student> cache = ignite.getOrCreateCache(cfg);
List<String> sqls = new ArrayList<String>();
sqls.add("java.lang.Integer");
sqls.add("select id, name, birthday from db1.student where id < 1000" );
sqls.add("java.lang.Integer");
sqls.add("select id, name, birthday from db1.student where id >= 1000 and id < 1000" );
cache.loadCache(null, , sqls.toArray(new String[0]));
Student s = cache.get(1);
System.out.println(s.getName() + "," + s.getBirthday());
ignite.close();
}
}
The code you showed here will be executed within your application, there is no magic happening. Usually it's a client node, however in your case it's started in server mode (probably by mistake): Ignition.setClientMode(false).
The data loading process will happen on each server node. I.e. each server node will execute SQL queries provided to load the data from the DB.
I have to register a plugin on Quick Find search on "Artilce" entity. When user enter any thing in quick find text box on Article entity at that time my plugin execute and return filter the data based on our business logic.
1.What event is fired when we find using quick find.
2.What message passes when this event is fired.
I have tried registering the plugin on RetrieveMultiple message but this is not triggered when we click on search in quick find.
Please help.
We have a Plugin registered on the RetrieveMultiple. We had a business requirement to search for the records, using WildCard by default.
Plugin Registration Details:
Message: RetrieveMultiple
Primary Entity:None
Secondary Entity:None
Pre-Operation
Code:
public const String QueryLiteral = "Query";
public const String LIKE = "%";
public void Execute(IServiceProvider serviceProvider)
{
String ParentEntity = String.Empty;
String OriginalSearch = String.Empty;
// Obtain the execution context from the service provider.
var ContextInstance = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
// Get a reference to the Organization service.
IOrganizationService ServiceInstance =
((IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory))).
CreateOrganizationService(ContextInstance.InitiatingUserId);
// Critical Point here - NOTICE that the InputParameters Contains the word Query
if (ContextInstance.Depth < 2 && ContextInstance.InputParameters.Contains(QueryLiteral) &&
ContextInstance.InputParameters[QueryLiteral] is QueryExpression)
{
QueryExpression QueryPointer = (ContextInstance.InputParameters[QueryLiteral] as QueryExpression);
//Verify the conversion worked as expected - if not, everything else is useless
if (null != QueryPointer)
{
// Check if the request is coming from any Search View
// We know this b/c Criteria isn't null and the Filters Count > 1
if (null != QueryPointer.Criteria && QueryPointer.Criteria.Filters.Count > 1)
{
ParentEntity = ContextInstance.PrimaryEntityName;
OriginalSearch = QueryPointer.Criteria.Filters[1].Conditions[0].Values[0].ToString();
OriginalSearch = String.Format(CultureInfo.CurrentCulture,
"{0}{1}", LIKE, OriginalSearch);
}
ConditionExpression NewCondition = null;
FilterExpression NewFilter = null;
if (null != QueryPointer.Criteria)
{
//Change the default 'BeginsWith'Operator to 'Contains/Like' operator in the basic search query
foreach (FilterExpression FilterSet in QueryPointer.Criteria.Filters)
{
foreach (ConditionExpression ConditionSet in FilterSet.Conditions)
{
if (ConditionSet.Operator == ConditionOperator.Like)
{
if (OriginalSearch != "")
ConditionSet.Values[0] = OriginalSearch;
else
{
OriginalSearch = QueryPointer.Criteria.Filters[0].Conditions[0].Values[0].ToString();
OriginalSearch = String.Format(CultureInfo.CurrentCulture,
"{0}{1}", LIKE, OriginalSearch);
ConditionSet.Values[0] = OriginalSearch;
}
}
}
}
}
}
ContextInstance.InputParameters[QueryLiteral] = QueryPointer;
}
}

We have raised a ticket with Microsoft to address this situaation.
The solution they provided was to modify the Database to make the message
SearchByTitleKbArticleRequest available in the plugin registration tool.
I currently dont remember the table that we updated a flag against these messages.
After updating the table we were able to register the plugin against the message
SearchByTitleKbArticleRequest
Then the plugin triggered and we modified the entity collection returned from there.
I have a very strange error with dapper:
there is already an open DataReader associated with this Command
which must be closed first
But I don't use DataReader! I just call select query on my server application and take first result:
//How I run query:
public static T SelectVersion(IDbTransaction transaction = null)
{
return DbHelper.DataBase.Connection.Query<T>("SELECT * FROM [VersionLog] WHERE [Version] = (SELECT MAX([Version]) FROM [VersionLog])", null, transaction, commandTimeout: DbHelper.CommandTimeout).FirstOrDefault();
}
//And how I call this method:
public Response Upload(CommitRequest message) //It is calling on server from client
{
//Prepearing data from CommitRequest
using (var tr = DbHelper.DataBase.Connection.BeginTransaction(IsolationLevel.Serializable))
{
int v = SelectQueries<VersionLog>.SelectVersion(tr) != null ? SelectQueries<VersionLog>.SelectVersion(tr).Version : 0; //Call my query here
int newVersion = v + 1; //update version
//Saving changes from CommitRequest to db
//Updated version saving to base too, maybe it is problem?
return new Response
{
Message = String.Empty,
ServerBaseVersion = versionLog.Version,
};
}
}
}
And most sadly that this exception appearing in random time, I think what problem in concurrent access to server from two clients.
Please help.
This some times happens if the model and database schema are not matching and an exception is being raised inside Dapper.
If you really want to get into this, best way is to include dapper source in your project and debug.
Is there any way to programmatically understand what properties there are for a custom model in Alfresco?
For example, data dictionary in oracle helps you to find what tables are defined by which column names and column data types.
My goal is a sample code in java which extracts all custom defined content models, their attributes, their attributes data types, etc. For example my sample code should return to me that there is a custom content Model which has an integer attribute with name 'No' and a string attribute with name 'Description'. I know this is possible with DictionaryComponent, But I don't know how should I use it.
Take a look at org.alfresco.service.cmr.dictionary.DictionaryService.
will your Java-code running in-context with alfresco (as part of the /alfresco webapp) or outside?
If your running in-context, then Alfreso Java Foundation API is your choice where DictionaryService is part of. just inject the bean into your java code.
If your code is running outside of alfresco, then Alfresco REST API or CMIS is your choice.
If you're still lost, then train yourself first. Jeff wrote some good articles http://ecmarchitect.com/alfresco-developer-series & also a book.
Also a good starting point - Alfresco Developer Docs: http://docs.alfresco.com/4.2/topic/com.alfresco.enterprise.doc/concepts/dev-for-developers.html
thanks a lot of alfresian responses, My code sample is something like below:
I found the sample code from : this URL

Session session = getSession();
boolean includePropertyDefintions = true;
for (Tree t : session.getTypeDescendants(
null, // start at the top of the tree
-1, // infinite depth recursion
includePropertyDefintions // include prop defs
)) {
printTypes(t, "");
}
}
public void printTypes(Tree tree, String tab) {
ObjectType objType = (ObjectType) tree.getItem();
String type = objType.getId();
if(true)//type.endsWith("hstcase"))
{
System.out.println(tab + "TYPE:" + objType.getDisplayName() +
" (" + objType.getDescription() + ")");
//Print some of the common attributes for this type
System.out.print(tab + " Id:" + "-----"+ objType.getId() + "-----");
System.out.print(" Fileable:" + objType.isFileable());
System.out.print(" Queryable:" + objType.isQueryable());
if (objType instanceof DocumentType) {
System.out.print(" [DOC Attrs->] Versionable:" +
((DocumentType)objType).isVersionable());
System.out.println(" Content:" +
((DocumentType)objType).getContentStreamAllowed());
Map<String, org.apache.chemistry.opencmis.commons.definitions.PropertyDefinition<?>> props = objType.getPropertyDefinitions();
Set<String> keys = props.keySet();
Collection<org.apache.chemistry.opencmis.commons.definitions.PropertyDefinition<?>> porpsAsCollection = props.values();
for(org.apache.chemistry.opencmis.commons.definitions.PropertyDefinition<?> p: porpsAsCollection)
{
//System.out.println(p.getDescription());
PropertyType pt = p.getPropertyType();
System.out.println("Display Name: "+ p.getDisplayName());
System.out.println("Local Name: "+ p.getLocalName());
System.out.println("Attribute Type: "+ pt.value());
}
}
System.out.println(""); // end the line
}
List<Tree> childs = tree.getChildren();
for (Tree t : childs) {
// there are more - call self for next level
printTypes(t, tab + " ");
}
}
I am trying to "insert" (or) "add a row" to Purchase Requisition using standard BAPI (PurchaseRequisition.CreateFromData).
I am using JCo3. The example in JCo3 indicates that we should use table.appendRow() OR table.insertRow() methods. I am trying with table.appendRow() & table.appendRows(1). When i try to insert a row, i dont get any error and the row is not inserted.
Below is the program i am trying to execute.
/** Below are the inputs required for this program to run /
/ Step 1 **/
String BAPI_NAME = "BAPI_REQUISITION_CREATE";
/** Step 2 **/
String query_input_column1 = "DOCUMENTY_TYPE";

String query_input_column2 = "PREQ_NAME";
String query_input_column2_value = "Name";

String query_input_column3_value = "U";
String query_input_column4 = "DELIV_DATE";
String query_input_column4_value = "20131101";
String query_input_column5 = "MATERIAL";
String query_input_column5_value = "DELL-RQ2013";
String query_input_column6 = "QUANITY";
int query_input_column6_value = 10100;
/** Step 3 **/
String targetTableUnderBAPI = "REQUISITION_ITEMS";
/** Step 4 **/
/** For the confirmation read the value from export parameter after insertion execution **/
String result_column1 = "NUMBER";
JCoDestination destination = null;
try {
destination = JCoDestinationManager.getDestination(DestinationManager.DESTINATION_NAME1);
JCoRepository repository = destination.getRepository();
JCoContext.begin(destination);
JCoFunction function = repository.getFunction(BAPI_NAME);
if(function == null)
throw new RuntimeException(BAPI_NAME + " not found in SAP.");
System.out.println("BAPI Name from function object: " + function.getName());
//function.getImportParameterList().setValue(query_input_column1, query_input_column1_value);
JCoTable table = function.getTableParameterList().getTable(targetTableUnderBAPI); //it is taken from the response value of metadata
//System.out.println("No of Columns: "+ table.getNumColumns());
System.out.println("Trying to execute append row");
table.appendRow();
table.setValue(query_input_column1,query_input_column1_value);
table.setValue(query_input_column2,query_input_column2_value);
table.setValue(query_input_column3,query_input_column3_value);
//table.setValue(query_input_column4,new java.util.Date(query_input_column4_value));
//skipped Other columns related code
try{
function.execute(destination);
}
catch(AbapException e){
System.out.println(e.toString());
return;
}
System.out.println("Let us check the result from export parameter");

} catch (JCoException e) {
e.printStackTrace();
}
finally
{
try {
JCoContext.end(destination);
} catch (JCoException e) {
e.printStackTrace();
}
}
I did not understand how to read the response and am trying to fetch it from exportParameters!!
Can anybody share a piece of code to insert and
getting confirmation response (do we get the PREQ_NO in response?)
I am adding date field value as "20131101", but not sure if the format and approach is right?
when i try to add Quantity column value, i get an error message complaining this column is not part of BAPIEBANC. But the column is visible in BAPIEBANC type.
any configuration on SAP side to be checked?
should i activate any fields in JCo side? if so, how
Please note that my knowledge on SAP is very limited.
Waiting for an expert's response.
Thanks.
First, you should take a look at SAP JCo documentation, e.g.
http://help.sap.com/saphelp_nw04/helpdata/en/6f/1bd5c6a85b11d6b28500508b5d5211/content.htm
Regarding your code:
Adding (one) row to the table looks right on first sight.
Your code says QUANITY instead of QUANTITY.
You should add date values as java.util.Date; if creating a Date from a String format, you should use java.text.DateFormat.parse(). See http://docs.oracle.com/javase/6/docs/api/java/util/Date.html (this is however Java specific and has nothing to do with JCo).
If changing anything in SAP, never forget to call BAPI_TRANSACTION_COMMIT in the end to finish the logical unit of work (aka transaction) or nothing will actually be changed.
If you don't like to fiddle with the more or less complicated and verbose JCo API, try using Hibersap which gives you a much nicer programming model when calling functions in SAP ERP: http://hibersap.org.
However, you will still need a basic understanding on how SAP function modules work technically (such as parameter types or data types) as well as on the domain specific model which lies behind them (in your case, creating a requisition). I.e. you may need to communicate with your SAP experts.
Here I added 2 types of insertion :
insertval() function for user defined module resides in sap with the help of abap programmer
Its an standard module for insert a ticket using jco to SOLMAN system. First you have to analyse import, export, table & structure parameters, and according to that you have to pass values and retrieve response. In second function it will return ticket n° after successfull insertion of ticket in solman.
I hope this sample code will help you, it worked for me.
