Getting ExceptionInInitializerError while calling a java class from db

Hi,
I have a class file working fine outside db. When I load that through loadjava and call it through pl/sql function, I get ExceptionInInitializerError.
Do you have any idea why this happens?
I am trying to login into a third party server in this class file. The error is caught at the statement I am sending the username/password and host name.
thanks,
Setareh

Setareh,
Here is an excerpt from the javadoc for ExceptionInInitializer:
Signals that an unexpected exception has occurred in a static initializer
or the initializer for a static variable.
Before running your function in SQL*Plus, do the following:
set serveroutput on size 1000000
exec DBMS_JAVA.SET_OUTPUT(1000000)Then you may get more information. If you don't then you may find more details in the Oracle log files in the "bdump" destination. The following query will tell you where that is:
select VALUE
  from V$PARAMETER
where NAME = 'background_dump_dest'Then, if you are still having trouble, post the entire error message and stack trace, as well as your java code.
Good Luck,
Avi.

  • Java.lang.NoClassDefFoundError while calling a java class from BPEL

    Hi,
    I'm calling a java class to convert JSON to XML using BPEL. I have imported all the necessary jar files in the project and compiling done successfully.
    But at runtime , i get the java.lang.NoClassDefFoundError: net/sf/json/JSON error.
    For this i placed all the necessary jars under FUSION_HOME/Oracle_SOA1/soa/modules/oracle.soa.ext_11.1.1/ path and restarted the server.
    But still i'm getting the same error at runtime.
    Did i missed any step? Let me know the procedure to solve this.
    Do i have to run ant or edit Manifest file after placing the jar?
    in one site i find we have to place the jars under <DOMAIN HOME>/lib directory. Is this correct?
    We are using SOA suite 11.1.1.6.
    Thanks,
    Terry

    Hi Karan,
    I have done placing the jars at FUSION_HOME/Oracle_SOA1/soa/modules/oracle.soa.ext_11.1.1/ and ran ant  -f build.xml .The build was successful without any error.
    I have even placed the jars in <DOMAIN HOME>/lib (/us2001/fmw/11.1.1.6/user_projects/domains/ohsdomain/lib) and did a server restart.
    After these activities, when i execute the composite, i still get the error in em console,

    Hi,
    Can u Please post the WSDL..here. I remember long back i resolved this kind of issue...when i was getting "*parameters is already defined in - - -*" while using ClientGen.
    Once i will get the WSDL may be i can recall it...
    If u have any problem in Posting the WSDL..in Forums .. then let me know I will send my E-Mail Address...
    As far as i remember ..it usually happens when we Run ClientGen task of WLS81 ON the WebService/WSDL generated by WebLogic 9.x or Above. Please let me know if this is the Case with you as well... . I remember there is a Patch for it...for WLS8 ClientGen task...I dont remember the Patch Number Exactly.
    Just For testing:
    Just Use WLS9.x ClientGen task On the Same WSDL
    <taskdef name="clientgen" classname="weblogic.wsee.tools.anttasks.ClientGenTask" />
    I am sure you will not see this issue... because the issue is there only with WLS8 Clientgen...
    Thanks

  • How can I call a java class from within my program?

    I was wondering if there's a platform independent way to call a java class from my program.

    Here's my scenario. I'm working on a platform independent, feature rich, object-oriented command prompt program. The way I'm designing it is that users can drop classes they write into my bin directory and gain access to the class through my program. For example, they drop a class named Network.class in the bin directory. They would type Network network at my command prompt and gain access to all the methods available in that class. They can then type system.echo network.ipaddress() at my prompt and get the system's ip address. I have it designed that there's a server running in the background and the clients connect to my port. Once connected the end-user can enter their user name and password and gain access to the system. When they type a command they actually call another java program which connects to my server using a seperate thread. They can then communicate back and forth. I have it set that everything has a process id and it's used to keep track of who called what program. Once the program is done it disconnects and closes. Rather than getting into the nitty gritty (I didn't want to get into heavy detail, I know how everything will work) I'm really interested in finding out how I can call a java program from my program. I don't want it to be part of the app in any way.

  • Calling my Java class from JSP page

    Hello, I am trying to call my Java class from my JSP page passing parameters to it and getting back a collection of result sets. Can someone tell me what I might be doing wrong:
    JSP code to call Java class:
    <%
    String strEssUser = "test";
    String strProcessingMonth = "JUL";
    String strProcessingYear = "2002";
    strQueryList=new ListReturn(strEssUser.toString(), strProcessingMonth.toString(), strProcessingYear.toString());
    %>
    I get this error when I try to run this JSP page using tomcat:
    C:\Program Files\Apache Tomcat 4.0\work\Standalone\localhost\em\jsp\Test_0005fSummarySBU_0005fscreen$jsp.java:77: Class org.apache.jsp.ListReturn not found.
    strQueryList=new ListReturn(strEssUser.toString(), strProcessingMonth.toString(), strProcessingYear.toString());
    I'm not sure if this problem is the way I am calling the Java class, or if I have a problem in the Java code itself. Can anyone help?

    Ok, I get a very strange error now:
    org.apache.jasper.JasperException: Unable to compile class for JSPerror: An error has occurred in the compiler; please file a bug report (http://java.sun.com/cgi-bin/bugreport.cgi).

  • How to call a Java class from another java class ??

    Hi ..... can somebody plz tell me
    How to call a Java Class from another Java Class assuming both in the same Package??
    I want to call the entire Java Class  (not any specific method only........I want all the functionalities of that class)
    Please provide me some slotuions!!
    Waiting for some fast replies!!
    Regards
    Smita Mohanty

    Hi Smita,
    you just need to create an object of that class,thats it. Then you will be able to execute each and every method.
    e.g.
    you have developed A.java and B.java, both are in same package.
    in implementaion of B.java
    class B
                A obj = new A();
                 //to access A's methods
                 A.method();
                // to access A's variable
                //either
               A.variable= value.
               //or
               A.setvariable() or A.getvariable()

  • Calling a Java Class from PL/SQL

    Hai,
    I need a technique of calling a class file and invoke its
    methods written in Java by PL/SQL for my intranet development.
    PLease let me know if you have really experienced and won.
    Thanks
    JOhnson

    First, to call a Java class from PL/SQL the class needs to be
    deployed to the database. you can check the 8i documentation for
    the instructions for loading Java into the database(LoadJava).
    The document contains information on how to load the Java and
    call it from PL/SQL. The following links should help.

  • I want to call External Java class from the PL/SQL

    Hi,
    I am using Oracle Apps R11i (11.5.7), I wanted to call external Java class from the PL/SQL. This external Java class is residing in another application server.
    How do I do this.
    I know one way. Develop C routine in Oracle Apps to call external java class and call this C routine from the PL/SQL.
    Is there any simple method available? or any other method?
    Thanks in advance.
    -Venkat

    First of all, this is a Java application you're talking about, right (i.e. it has a main() function)? It's not just a class that you're trying to instantiate is it? If it's an application, you obviously have to start a new virtual machine to run it (rather than using the virtual machine built into the database like stored java). I'm a little leary of your mention of an "application server" as this would more commonly mean that a virtual machine is already over there running with access to this class. In which case, you'd typically interface with SOAP or some other RPC API.
    All that aside, as long as you have physical disc access (through NFS or whatever) to the class file, you could use a java wrapper class with a system call to do this. In fact, there is a thread in just the last day or so on this very forum that has the code to do just that (see " Invoking OS Commands from PL/SQL"). However, it's worth noting that the virtual machine will be running on the database server in this case and not the application server.

    any idea???
    thanks.

    I think the OP wants to use a class file as a COM object. I've never done that, but this URL:
    http://support.microsoft.com/default.aspx?scid=KB;EN-US;q167941&
    seems to indicate that you should have placed the class file into the c:\winnt\Java\TrustLib\ sub directory before you ran the JAvaReg bat file - I would re-run JavaReg and bounce IIS and associated services and see if that works out.
    Good Luck

  • Calling Custom Java Class from WCC?

    How do I call a custom Java class from WCC when a certain metadata field is set to 'On' and at the time of check-in?
    Thank you,
    Randy

    Randy,
    You would only use the Intradoc classes if running as a service, service handler, filter or class alias as a component within WebCenter Content. In this case, since it is running inside WebCenter Content, you do not need to bundle the Intradoc classes since they are already on the classpath.
    If you are trying to code something that will not run inside WebCenter Content, you want to use RIDC: http://jonathanhult.com/blog/2012/12/ridc-examples/
