Weblogic is shutting down automatically very often. In the error log "+ set +x" is getting printed. There is no message in the log , stating weblogic is stopped .. but when we look at the process running in unix machine using ps command java process is not running. this is happening very very often.. 4 times or 5 times in a day when the users are accessing ..

Any inputs on the same y this is happening..

this is quite urgent ....

I have got it right.. Its the classpath issue. I had to put the jar in the classpath and mention it in the weblogic startup classpath.

Hi ,
I m trying to deploy a application in weblogic 8.1.This application was previously deployed in weblogic 7.0 and it was working fine. While trying to deploy the application in 8.1 , it give me java.lang.NoClassDefFoundError.

But that class file is there in the ear. Is it any version problem ???

Exception is as follows,

<May 25, 2006 1:03:00 PM GMT+05:30> <Error> <Deployer> <BEA-149201> <Failed to complete the deployment task with ID 2 for the application Orbicollect91.

I Still have a doubt , Actual scenario goes like this ,

I have a jsp file "JSP1.jsp", servlet "FILE1.class" and a class file "FILE2.class". JSP and servlet is referring to "FILE2.class" class file. I transfer the control from jsp to servlet and then back to the same jsp with certain values set to display in the client side.Control will be transferred to servlet when the form is submitted..
Why isnt the same problem coming with servlet class files. I m facing this problem only with "FILE2.class" i.e ordinary class and not with "FILE1.class" which is a servlet.I compile both files in the same manner.

Hope I m clear...

Hi,
I have got it solved.. I jus compiled the ManualBalanceVO.java using the option "-source 1.4" . This creates the class files with version 48.0

Background information:
Java 1.4 creates class files labeled with version 48.0
Java 1.5 creates class files labeled with version 49.0

Java 1.4 can't run class files labeled with version 49.0

Thanx ....

I m getting the following error when i tried to view the jsp file after deploying the .war file in weblogic.. The error is as follows,
C:\DOCUME~1\KAVITH~1.SIV\LOCALS~1\Temp\jsp_servlet\__sample.java:17: cannot access samples.vo.ManualBalanceVO
bad class file:

C:\bea\user_projects\domains\mydomain\myserver\.wlnotdelete\extract\myserver_Samples_Samples\jarfiles\_wl_cls_gen.jar(samples/vo/ManualBalanceVO.class)
class file has wrong version 49.0, should be 48.0
Please remove or make sure it appears in the correct subdirectory of the classpath.
import samples.vo.ManualBalanceVO; //[ /Sample.jsp; Line: 1]
^
1 error

I m referring to this ManualBalanceVO which is in the package "samples.vo"

Help me out.. Thanx in advance...
