EJB is not throwing exception to calling Action class in Unix environment

Hi
We are using Weblogic Server 9.2.3.0.
One of our EJB is not throwing exception to calling Action class in Unix environment. Its working fine in Windows.
Somehow the EJB is swallowing the exception.
any idea? I suspect it may be environmental issue?
thank you

Thanx for your reply.. I just found a solution and would like to share that with you. There are some default request parameters passed by the portal to the action class. "strutsAction" is one of them. If you print this parameters, you will see that it contains the complete url of your action. Now you can use String manipulation to extract the value of the parameters.
I know its a crude solution. But it works fine.

Class not found exception for the startup class defined.

iam using weblogic server 10 and bea jrockit 1.5.0.12.
i have created a startup class in the admin console for a web project and i have deployed the war file using the console in a user defined domains, user project directory.
when i start the server, iam getting class not found exception for the startup class.
But, the startup class is available in the web archive (war). how should we add the classes and jars in the war to the classpath in setDomainEnv.sh or is there any other setting available in the console to enable this.

Hello Julius,
yes sure, we can move this post to the NW admin forum. I have already posted similar thread on sun forums. I was hoping that someone from SAP SDN already tackled this problem and if not someone specialized in J2EE Engine could troubleshoot me from the class problem I'm getting. I don't know if it's specific from the agent or if this ClassNotFound is a general SAP J2EE Engine error relating to a library not correclty defined.
Kind regards,
Tanguy Mezzano

Java Does Not Throw Exception When Writing To Read-Only Files

I have noticed that when I try to write to a read-only file in a window environment, Java does not throw an IOExcpetion, it just dosn't write to the file.
I am writing an FTP server and here is the code:
     public static long copyStream(InputStream in, OutputStream out)throws IOException
          IOException exception = null;
          long copied = 0;
          try
               byte buffer[] = new byte[1024];
               int read;
               while((read = in.read(buffer)) != -1)
                    out.write(buffer, 0, read);
                    copied += read;
          catch(IOException e)
               //ensures that the streams are closed.
               exception = e;
          try
               in.close();//ensures output stream gets closed, even if there is an
               //excption here.
          catch(IOException e){exception = e;}
          out.close();//try to close output.
          if(exception != null)
               //exception is not null, an exception has occured.
               //rethrow exception.
               throw exception;
          return copied;//all ok, return bytes copied.
     }Is this a bug in JAVA VM? Is so, how should I report it?

Throwing exceptions on an extended class?

I currently have a class that I need to extend and one method of that class that I need to override.
Assuming the following:
public BaseClass {}
public BarClass extends BaseClass {
    public configure () {}
public FooClass extends BarClass {
    @Override
    public configure () {
}I want to throw custom exceptions from FooClass, but haven't as yet found the magic behind doing that. If I add a throws statement to FooClass, eg.
public FooClass extends BarClass throws MyException{
    @Override
    public configure () {
        throw new MyException();
}javac complains that a "{" was expected on the FooClass declaration.
If I add the throws to the configure() method in FooClass, javac complains that the overridden class does not throw MyException. eg.
public FooClass extends BarClass{
    @Override
    public configure () throws MyException {
        throw new MyException();
}First, should I be able to throw my own exceptions on overridden methods of an extended class? If yes, what am I missing?

Aha! I see the problem.
My exception was extending Exception, not RunTimeException.
Just getting it to compile doesn't mean it's right. There are specific reasons for checked vs. unchecked exceptions. You shouldn't add an unchecked exception just to get something to compile when the parent class doesn't throw any checked exceptions. RuntimeException and its descendants specifically indicate a bug in code, not an exceptional but expected case that arises at runtime.
You should look at the docs for the parent class to find out what it does when there's an error. Don't break its contract.Hmmmm. That presents a problem. The original classes do virtually nothing for error handling, but are implemented in a number of legacy apps, so I really can't do much there (in addition to the whole developer "owner/ego" issue with the original author). These legacy apps regularly blow up because the classes used rarely even bother to check inputs beyond Java type matching. Eg., a utility class that doesn't check date ranges to ensure that the maximum date is greater than the minimum date, etc.
So, for new apps, I would like to extend several of the existing classes to implement better handling of what I would consider exceptional circumstances (eg. minDate > maxDate).
That's basically the motivation here. I suppose I probably shouldn't waste my time and just leave it as is and do all the checking in my app.

One-way soap call do not throw exception

Hello,
I prepared a client for web service with JWSDP-2.0. wscompile generated proxy classes. The web service uses "basic authentication". Now comes my problem. wscompile generated stub which calls
_sendOneWay((java.lang.String) _getProperty(ENDPOINT_ADDRESS_PROPERTY), _state);Because the web service is defined as: void ENCRYPTED_MESSAGE(SOAPElement)
When basic authentication fails (I get HTTP 401 code - which I can see in debug created by JVM parameter -Djavax.net.debug=all ) then NO EXCEPTION is fired!!!
When I change the wsdl and add dummy output parameter, then send((java.lang.String) getProperty(EN... is generated and authentication fires exception. But this is not the right way to do it.
My question is - can I make wscompile to generate Stub without _sendOneWay?
Thanks for yout time and attention!

Perist not throwing exception

Hi everyone,
I am new to JPA, and currently trying to persist/update an entity to a HSQL database. According to the API, the persist method of the class EntityManager, throws an exception if we try to persist an entity which already exists, but in my case, it seems to update the entity, if it exists.
Here's a snippet of the commit code
public void commit(Object obj){
        if(entityManager == null) {
            entityManager = getEmf().createEntityManager();
        if(entityTransaction == null){
            entityTransaction = entityManager.getTransaction();
        if(!entityTransaction.isActive()){
            entityTransaction.begin();
        entityManager.persist(obj);
        try{
            entityTransaction.commit();
        } finally {
            close();
private void close(){
        EntityManager tempEntityManager = entityManager;
        EntityTransaction tempEntityTransaction = entityTransaction;
        entityManager = null;
        entityTransaction = null;
        try{
            if(tempEntityTransaction != null && tempEntityTransaction.isActive()){
                tempEntityTransaction.rollback();
        } finally{
            if(tempEntityManager != null) {
                tempEntityManager.close();
    }As you can see, my commit method calls the persist method always, so if I try to commit an entity twice, it should throw an exception, but instead it updates the entity. Could any of you tell me why this is the case?

Look at the setLenient method.
Also, read the part in the docs about when the number of characters does and does not matter when parsing.

          Hi Sanjay and Vel,
          We have been running internal test suites using the Oracle 8.1.7 thin driver,
          and did not run into this problem. I suspect this may be related to the database
          setup or environment. We would also like to understand why it happens. I would
          suggest either of you to report this problem to Oracle support and see whether
          they could shed some light on this.

Constructor can throw exception or Not ?

Anybody please tell me if the constructor throws an exception or not ?
Please reply soon
Thanks
Amitindia

A constructor can throw an Exception. However I
would suggest throwing the generic Throwable, Error,
Exception or RuntimeException rather than a specific
exception is bad practice and you should choose an
appropirate exception to throw.All depends on wich kind of exception you are throwing,checked or unchecked. It's an even worse form to throw a RE, Error, or Throwable when you are throwing in fact a checked exception.
Nevertheless, I do agree, you must always strive to not throw exceptions, of any kind, in your construtor code. Construtors should be simple and reliable. Unles you have a very compelling reason to not do it, try to isolate the risky parts of the code where they are called ofter object construction or class loading.
May the code be with you.

Hi Zakir,
I am not sure but it would be nice if you can do following
Try search ULS log with correlation id and find exact error and share here. If not able to find do following
Or in catch block write
Response.Write(ex.ToString());
and check what exception its giving.

Dispatching GridSelectionEvent throw exception at runtime - A build issue with FB 4.5

This is a strang probelm I am facing with.
My code dispatches GridSelectionEvent after setting girds' selected item in one logic path. Following is code lines -
myDataGrid.selectedItem = instanceTag;
myDataGrid.dispatchEvent(new GridSelectionEvent(GridSelectionEvent.SELECTION_CHANGE));
Flash player throws following error on above statements encounter -
TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at spark.accessibility::DataGridAccImpl/eventHandler()
    at flash.events::EventDispatcher/dispatchEventFunction()
    at flash.events::EventDispatcher/dispatchEvent()
    at mx.core::UIComponent/dispatchEvent()
I am saying it is a strang for me because when I use swf file generated by Flex Builder (4.5)'s export to release build, it does not throw error and code works fine as expected.
But, when I user swf file generated by Ant script, I face the above issue.
The Flex builder settings is as shown in following image -
Ant mxmlc script is as follow -
<mxmlc
           file="${basedir}/src/AppMonConfigWizard.mxml"
            static-rsls="false"
           keep-generated-actionscript="false"
           output="${basedir}/bin-release/AppMonConfigWizard.swf" >
     <locale>en_US</locale>
      <load-config filename="${FLEX_HOME}/frameworks/flex-config.xml"/>
      <source-path path-element="${FLEX_HOME}/frameworks"/>
      <source-path path-element="${basedir}/src/locale/{locale}"></source-path>
      <compiler.library-path file="${basedir}/../wizard_framework/bin/wizard_framework.swc" append="true"/>
     <compiler.library-path file="${basedir}/../../utils/bin/utils.swc" append="true"/>
      <include-resource-bundles>ErrorMessages</include-resource-bundles>
      <include-resource-bundles>Strings</include-resource-bundles>
</mxmlc>
As mentioned earlier that following statements cause exception -
     myDataGrid.selectedItem = instanceTag;
     myDataGrid.dispatchEvent(new GridSelectionEvent(GridSelectionEvent.SELECTION_CHANGE));
If I change it to
     myDataGrid.setSelectedIndex(<some index value>)   /*selectedItem replaced with setSelectedIndex*/
     myDataGrid.dispatchEvent(new GridSelectionEvent(GridSelectionEvent.SELECTION_CHANGE));
it does not throw exception. I would like to mention that myDataGrid.selectedItem = instanceTag; does sets the selected item but then in that case issue arises when dispatching event.
I my application, similar statemetns were lot at many places (as there were no such issue with SDK 3.1 which was using earlier) so instead of making changes there, it would be better to imitate the build that Flex builder uses when exported the release build.
Thanks in advance,
Prithveesingh Zankat.

Exceptions - documentation on which methods throw exceptions ?

Hi, does anyone know where I can find full documentation on iphone SDK methods
The iphone SDK documentation seems to be incomplete.
For instance, the discussion section of the SDK documentation for NSMutableArray addObject method doesn't mention anything about exceptions.
However, the method could throw an exception (and this is mentioned in http://developer.apple.com/documentation/Cocoa/Reference/Foundation/Classes/NSMu tableArray_Class/Reference/Reference.html)
I'm assuming that alloc will not throw exceptions and that it will just return nil if no memory is available. However, I haven't found any documentation that states this.
Does anyone have a pointer to Apple documentation for methods (that includes information on any (and all) exceptions thrown by the method and also includes information on possible return values for the method) ?

There is this
http://java.sun.com/products/jdbc/driverdevs.html
I am pretty sure that there is little in the meta data stuff that has to be supported.
