How To Handle SQL Exceptions in  Session EJB Bean

Hi,
we are working on toplink JPA. My use case is I have an emp table with columns as "empid" , "emp name" , "job" with "empid" as primary Key. Here I'm creating a record in the Database by using a jspx page. Here My problem is when I'm entering a duplicate value for the empid I'm getting "ORA-00001: unique constraint (constraint_name) violated" . I'm able to catch the exception in the jspx backing bean where I'm calling the JPA insert method, But i could not catch the exception in the sessionEJB Bean. Is there any way to catch such exception in the sessionEJB.
could anyone help me out.
Thanks in Advance.

PrapanSol

You should be able to call flush on your EntityManager in your SessionBean to trigger the exception.
Note that the transaction will still be rolled back even if you catch this exception.

  • How to handle sql exceptions properly

    Hi,
    Using Jdev 11.1.1.1.0 and JPA/Toplink
    Our application is used to modify a number of different tables. The tables are mapped in EJB entities and are exposed in session beans which calls the proper methods from the DAOs. We use ADF Rich components in our view project and we have a lot of validation for preventing primary key violations etc. But obviously we can't control everything and we need some exception handling. As it is now, if e.g an sql exception occurs, it will pop up a huge error dialog with the stack trace and the page rendering will fail etc and sometimes needs to restart.
    So, I'm not sure how to approach this. How do we catch these exceptions, notify the user, and stop the page rendering so that it doesn't completely shut down...I've searched around and found some useful information, but since we've never done this before it's a little hard to put things together. Could you please give me some easy examples for this?
    Thank you!
    André

    Hi, thanks for your reply.
    Yes, I have tried to override both getDisplayMessage and reportException. I now used the exact same code as in the example you referred to, and still I get the same result.
    So just to make it clear... If do an insert that causes integrity constraint violation, I get in my console:
    Internal Exception: java.sql.SQLIntegrityConstraintViolationException: ORA-00001: unique constraint violated
    Error Code: 1
    Call: INSERT INTO etc etc... When this happens, a huge popup appears in my page:
    javax.ejb.EJBException: BEA1-002236FD9E083057A4BD: weblogic.transaction.internal.AppSetRollbackOnlyException

  • How to handle XScript Exceptions ?? HELP !!

    hey buddies !!!
    I am getting the following exception in the browser for some jsp that is using XSCript.
    "Caught exception when evaluating expression "MIDC PHASE II DOMBIVALI {E}" with available binding contexts [actionForm, pageFlow, globalApp, request, session, appication, pageContext, bundle, container, url, pageInput]. Root cause: com.bea.wlw.netui.script.xscript.IllegalContextStateException: The context "E" could not be found. "
    Its okay that i am gettign this exception but i want to to know how to handle this exception. I tried using a try catch block but it didnot catch the exception and it still showed on the screen. I want to know how to handle this exception in the jsp ...
    Please help me ...thanks a lot !!!
    Nikhiol

    Nikhil--
    Can you paste in the tag (with the attributes) that is throwing the expression?
    Are you trying to data bind to "{E}"? If so, that's not a supported NetUI data binding context
    and the exception is legit. There isn't really a way to "handle" it -- it's more of a runtime error
    that occurs during regular development. When the application is deployed, such exceptions shouldn't
    occur.

  • How to handle the Exception in GP using executable callabel object.

    Hi all,
            I handled an exception in GP using Background callable Object. That is working fine.
    (Ex: Exception_No_User_Found). The Problem is I am not able to handle the exceptions for normal callable object. I have done the same thing as i did in background callable object except implementing IGPBackgroundCallableObject Class.  I have created an WebDynpro DC Project where in getDescription method i declared an Exception and in execute method of component controller I caught the exception if no user found.
    Then i created an callable object for this simple DC project. but that is not working i could not catch the exception. when i execute the process it is asking the User ID if i give the wrong userId it is not refreshing back to the user id input form.
    But if i test that simple callable object separately it is throwing an Exception when I give the wrong input..
    but the same thing is working fine using background callable object.
    I couldn't handle the exception for the simple callable object or executable callable object.
    Please If anyone bring me the solution that would be appreciated.
    Thanks in advance.

  • How to handle multiple tables data in Entity Beans?

    How to handle multiple tables data in Entity Beans?
    i mean, my bean (non trivial) is responsible for frequent
    insertion in one table and some deletion on another table.
    Can anyone of you...please..?

    Is your data model right? If you are adding in one and deleting in another it sounds to me more like a process that an entity, in which case you may revisit your data model and simplify it, add in a session bean with the process method to co-ordinate between the two.
    However, if you want to map multiple different tables within a single entity bean it is possible and just part of the mapping. How you actualyl specify it depends on which implementation you are working with.

  • How to handle multiple exception types in JSF 2?

    I'm trying to handle multiple exception types in JSF2, including a default error page for any unexpected exception types. The problems I'm having are:
    1) ViewExpiredException is handled only when no generic exception handler is specified
    2) "Regular" exceptions like NullPointerException are never handled
    My managed bean:
    @Named
    @SessionScoped
    public class MyController implements Serializable {
    /* A method that does nothing */
    public void doNothing() {
        //do nothing
    /* Generate a null pointer exception on purpose */
    public void generateNpe() throws NullPointerException {
        Object x = null;
        x.toString();
    My test page to generate the exception:
    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

        </h:form>
    </h:body>
    </html>
    My web.xml:
    <!-- Redirect all NPEs to this page; this never works! -->
    <error-page>
        <exception-type>java.lang.NullPointerException</exception-type>
        <location>/error/error003.jsf</location>
    </error-page>
    <!-- Redirect all VEEs to this page; this works fine if the next section is excluded -->
    <error-page>
        <exception-type>javax.faces.application.ViewExpiredException</exception-type>
        <location>/error/error002.jsf</location>
    </error-page>
    <!-- This grabs everything, even with the previous sections defined.  If I exclude this error-page section, VEE works fine but NPE still does not get redirected -->
    <error-page>
        <exception-type>java.lang.Exception</exception-type>
        <location>/error/error001.jsf</location>
    </error-page>My questions are as follows:
    1) How can we handle "regular" java exceptions like NPE?
    2) How can we define a catch-all for unexpected exception types, while still respecting specific exception handlers for VEE, etc?
    Thanks,

  • How to create ErrorLog file from Session EJB

    Hi my friends,
    I have the need to write the Exception Errors from Session EJBs into log file. The problem is my project is the multi-user application and many EJBs' user transactions need to log the errors to only one log file, if I use EJB named ErrorLogWriter as the main component for log file writer and the other EJBs just reference to this EJB to log the errors, each request will create one instance of ErrorLogWriter therefore we can't access to only one log file. Somebody told me that it should be OK if we use servlet as the log file writer because only one servlet instance is initialized for multi-requests, and the other EJBs just call this servlet. Do you have any ideas or suggestion for this matter? If using servlet is the right solution, can I call servlet method from Session EJBs? and how?
    Thanks in advance for any help

  • How to handle system exception in Sync communication without BPM? Help!

    Hi Experts
       I have a Synchronous scenario in XI: webservice <------>RFC SAP R/3.
      Webservice is making a sync call to RFC FM in SAP R/3 system.
       I want to handle system exception when SAP R/3 is down and send an email alert.    
       Can I achieve this in graphical mapping without BPM? How? Kindly provide necessary steps/screenshots for the same.
       Are there any other alternatives for handling system exception apart from mapping and BPM?  
    Thanks
    Gopal

    Hi GopalKirshna,
          Yes,You can handle the Exception if at all you are using the RFC.You can achieve this without using BPM.
       Using Fault message you can catch the System Exception and even the primary role for Fault Message is to catch the RFC Exceptions.
       Please refer the Fault messages Notes to achieve this you will understand better.
    Hope I am clear.
    Please let me if you have any more queries regarding this..!
