I have an error that I cannot logically understand.
I am implementing RSS processing app. The logic is that user takes link of some RSS feed and adds to database. If the feed already exist in database, it takes the id of feed and adds it to subscriptions of the user.
Here is the code:
if (existfeed == null) {
feed = loadFeed(url, syndfeed);
em.persist(feed);
if (feed.getFeedId() == null) {
return "Persist of feed failed";
}
uf.setFeedId(feed);
uf.setUserId(user_id);
try {
em.persist(uf);
loadFeedItems(syndfeed, feed);
//boolean ufadded = uf.addUserFeed(em);
} catch (NoResultException ex) {
return "Persist of userfeed failed";
} catch (PersistenceException ex) {
return "Persist of userfeed failed, em";
}
//boolean ufadded = uf.addUserFeed(em);
//return true;
return "Feed added";
} else {
dbFeed = getFeed(feed.getLink());
if(dbFeed==null)
return "Faile to get feed from database";
//http://appleinsider.ru/feed
uf.setFeedId(dbFeed);
uf.setUserId(user_id);
try {
em.persist(uf);
} catch (PersistenceException ex) {
//System.out.println(ex.getMessage());
return "Unable to persist userfeed";
}
return "Feed added, existing";
}
However, if user added a feed, another user cannot add it and there is the error:
Caused by: java.lang.NullPointerException

I just dont see why would it fail.
One of my opinion is that possibly, EntityManager somehow is null. But, in first part of if statement it works.
UPDATE: I tried to use EntityManager find method, it resulted same error. So, definitely, EntityManager is somehow null in second part of if statement.
Thanx for all the help.

I'm new to grails so hoping someone will be patient and give me a hand. I have a controller that creates a PDF. If the user clicks more then one time before the PDF is created I get the following error. Below is the code for the creation of the PDF.

You need to catch the exception, if you wish to not do anything with it then as below in the catch nothing going on.. after it has gone through try and catch if still no file we know something has gone wrong so we render another or same view with error this time. After this it returns so it won't continue to your other bit which checks report type i.e. pdf or html
..
//declare file (def means it could be any type of object)
def file
//Now when you expect unexpected behaviour capture it with a try/catch
try {
file = jasperService.generateReport(reportDef).toByteArray()
}catch (Exception e) {
//log.warn (e)
//println "${e} ${e.errors}"
}
//in your scenario or 2nd click the user will hit the catch segment
//and have no file produced that would be in the above try block
//this now says if file == null or if file == ''
// in groovy !file means capture if there nothing defined for file
if (!file) {
//render something else
render 'a message or return to page with error that its in use or something gone wrong'
//return tells your controller to stop what ever else from this point
return
}
//so what ever else would occur will not occur since no file was produced
...
Now a final note try/catches are expensive and should not be used everywhere. If you are expecting something then deal with the data. In scenarios typically like this third party api where you have no control i.e. to make the unexpected expected then you fall back to these methods
1- Client Side : Better is to disable button on first click and wait for response from Server.
2- Catch Exception and do nothing or just print error log.
// get/set parameters
def file
def reportDef
try{
reportDef = jasperService.buildReportDefinition(reportParams, request.getLocale(), [])
file = jasperService.generateReport(reportDef).toByteArray()
}catch(Exception e){
// print log or do nothing
}
if (file){
// render file according to your conditions
}
else {
// render , return appropriate message.
}
Instead of catching Exception, Its better to catch IOException. Otherwise you will be eating all other exceptions as well. Here is how i handled it.
private def streamFile(File file) {
def outputStream
try {
response.contentType = "application/pdf"
response.setHeader "Content-disposition", "inline; filename=${file.name}"
outputStream = response.outputStream
file.withInputStream {
response.contentLength = it.available()
outputStream << it
}
outputStream.flush()
}
catch (IOException e){
log.info 'Probably User Cancelled the download!'
}
finally {
if (outputStream != null){
try {
outputStream.close()
} catch (IOException e) {
log.info 'Exception on close'
}
}
}
}
The api is streaming large volume of data. after performing validation and opening up the connection to backend then creating the jdbc statement, we return httpresponse ok status with the header. The problem we see is that when the streaming breaks, the client does not get error code and only thing we can do is just close the channel.
Here is how we send the status back at the begining;
HttpResponse response = new DefaultHttpResponse(HTTP_1_1, OK);
response.headers().set(CONTENT_TYPE, MimeTypes.TEXT_JSON_UTF_8);
response.setChunked(true);
response.headers().set(Names.TRANSFER_ENCODING, Values.CHUNKED);
Channel ch = ctx.getChannel();
// Write the initial line and the header.
ch.write(response);
When anything fails during the streaming, the error is captured by the catch block;
} catch (Exception e) {
ctx.getChannel().close();
String msg = "Error while streaming dynamic content from backend datasource " + ((DatasetDynamic) datasets[0]).getDbDataSourceName();
error(e, msg);
debug("uriNodes=" + this.uriNodes + "; params=" + this.params);
throw new Exception(msg, e);
} finally {
As you see in the catch block, to notify the client, something went wrong, all it is doing is;ctx.getChannel().close();
Is there anyway we can send proper httpresponse with error back to the client?
Looks like you can send httpresponse anytime thru the channel, it does not have to be as header;
} catch (Exception e) {
// Any exception here means an error in the middle of chunk streaming, we
// send back http 500 to the client to inform the failure
ResponseErrorStatus status = new ResponseErrorStatus(ServiceErrorStatus.INTERNAL_SERVER_ERROR,
" error: " + e.getMessage() + (e.getCause() != null ? (" - caused by: " + e.getCause().getMessage()) : ""));
HttpResponse response = new DefaultHttpResponse(HTTP_1_1, status.serviceErrorStatus.httpStatus);
Channel ch = ctx.getChannel();
ch.write(response);
I have two JLists, the other has categories of weapons (I'm doing roleplaying character creation software) and the other has items in that specific category. I want the items to change according to category
At the moment jList with items swaps its DefaultListModel every time user changes category (every DefaultListModel variable has different sets of items) this somehow produces NullPointerException whenever user clicks an Item after changing category.
I've tried to search this online and I have read the examples with JList's, but I haven't been able to solve the problem.
Here is the related code
private void jList1ValueChanged(javax.swing.event.ListSelectionEvent evt) { //Kategory
String selection = jList1.getSelectedValue().toString();
if(selection.equals(settings.weapon_classes[0])){
jList2.clearSelection();
jList2.setModel(model_l_pistols);
jList2.validate();
}
if(selection.equals(settings.weapon_classes[1])){
jList2.clearSelection();
jList2.setModel(model_m_pistols);
jList2.validate();
}
}
private void wpn_available_valuechanged_listener(javax.swing.event.ListSelectionEvent evt) {
Weapon wpn = new Weapon(); //The details of selected weapon are stored here for desplaying
try{
String wpn_name = jList2.getSelectedValue().toString();
if(jList1.getSelectedValue().equals("Light pistols")){
wpn = controller.get_Weapon(wpn_name, settings.light_pistols); //Stores right item details from array in settings class
}
if(jList1.getSelectedValue().equals("Medium pistols")){
wpn = controller.get_Weapon(wpn_name, settings.medium_pistols);
}
}catch(Exception e){
System.out.println(e + "String wpn_name = jList2.getSelectedValue().toString();");
}
}
And here is the errormessage I get when running my program with NetBeans IDE (first line includes my try/catch block printing of exception:
java.lang.NullPointerExceptionString wpn_name = jList2.getSelectedValue().toString();

Possible error could be in this line
String selection = jList1.getSelectedValue().toString();
jList1.getSelectedValue() can be a null value so when the toString() function calls against a null it throws an exception
Use this instead to avoid the exception
String selection = String.valueOf(jList1.getSelectedValue());
This way if it is a null selection you will just get back the String value of null;
I have a question... I have an application using sqlite to save some data.Everything works perfectly, meaning I can add, delete, view data. The data are persistent when the application goes into background. Now, when I remove the application from memory or reboot the iPhone, the database is corrupted and all the data are messed up !
I have a class call dbAccess where all the database actions are define(add, delete, retreive rows). At the end I have a finalize action, that finalize all the statement used and then close the database.
+ (void)finalizeStatements{
NSLog(#"Finalizing the Delete Statements");
if(deleteStmt) {
NSLog(#"Delete Statement exist... finalization");
sqlite3_finalize(deleteStmt);
deleteStmt = nil;
}
NSLog(#"Finalizing the Add Statements");
if(addStmt) {
NSLog(#"Add Statement exist... finalization");
sqlite3_finalize(addStmt);
addStmt = nil;
}
NSLog(#"Finalizing the Store Statements");
if(storeStmt) {
NSLog(#"Store Statement exist... finalization");
sqlite3_finalize(storeStmt);
storeStmt = nil;
}
NSLog(#"Finalizing the Agent Statements");
if(agentStmt) {
NSLog(#"Agent Statement exist... finalization");
sqlite3_finalize(agentStmt);
agentStmt = nil;
}
NSLog(#"Closing the Database");
if(database) {
NSLog(#"The database exist... closing it");
sqlite3_close(database);
}
}
This method is called by the application delegate when applicationDidEnterBackground and applicationWillTerminate. An openDatabase method is call when applicationDidBecomeActive.
Any ideas why the database is corrupted ?
Thanks.
First off, check out fmdb or some other proven wrappers. You can also browse the code.
Not sure if there's enough info to know why it's corrupt. But, you should get return codes from ALL sqlite3_xxx calls and log at a minimum to understand what's going on or you may just be blasting past an issue.
Also, make sure to call sqlite_errmsg which will offer more clues if the return code is not success.
In my wrapper, I do this in close. It's expected that statements are finalized bu handled if not. I have a statement cache which on clear finalizes each statement.
:
- (void)close
{
if (_sqlite3)
{
NSLog(#"closing");
[self clearStatementCache];
int rc = sqlite3_close(_sqlite3);
NSLog(#"close rc=%d", rc);
if (rc == SQLITE_BUSY)
{
NSLog(#"SQLITE_BUSY: not all statements cleanly finalized");
sqlite3_stmt *stmt;
while ((stmt = sqlite3_next_stmt(_sqlite3, 0x00)) != 0)
{
NSLog(#"finalizing stmt");
sqlite3_finalize(stmt);
}
rc = sqlite3_close(_sqlite3);
}
if (rc != SQLITE_OK)
{
NSLog(#"close not OK. rc=%d", rc);
}
_sqlite3 = NULL;
}
}
Why am i getting this error message?

I am trying to create a Lucene index using documents that are created using Lire. When i am getting to the point where it tries to create a document using the document builder it gives me this error message.
input paramaters first run:
filepath: "test_archive" (this is a image archive)
whereToStoreIndex: "test_index" (Where i am going to store the index)
createNewIndex: true
Since the method is recursive (see the if statement where it checks if is a directory) it will call itself multiple times but all the recursive calls uses createNewIndex = false.
Here is the code:
public static boolean createIndexBatch(String filepath, String whereToStoreIndex, boolean createNewIndex){
DocumentBuilder docBldr = DocumentBuilderFactory.getDefaultDocumentBuilder();
try{
IndexWriter indexWriter = new IndexWriter(
FSDirectory.open(new File(whereToStoreIndex)),
new SimpleAnalyzer(),
createNewIndex,
IndexWriter.MaxFieldLength.UNLIMITED
);
File[] files = FileHandler.getFilesFromDirectory(filepath);
for(File f:files){
if(f.isFile()){
//Hopper over Thumbs.db filene...
if(!f.getName().equals("Thumbs.db")){
//Creating the document that is going to be stored in the index
String name = f.getName();
String path = f.getPath();
FileInputStream stream = new FileInputStream(f);
Document doc = docBldr.createDocument(stream, f.getName());
//Add document to the index
indexWriter.addDocument(doc);
}
}else if(f.isDirectory()){
indexWriter.optimize();
indexWriter.close();
LireHandler.createIndexBatch(f.getPath(), whereToStoreIndex, false);
}
}
indexWriter.close();
}catch(IOException e){
System.out.print("IOException in createIndexBatch:\n"+e.getMessage()+"\n");
return false;
}
return true;
}
It sounds like you are missing a java library.
I think you need to download Caliph & Emir, that may be used indirectly by Lire.
