[resolved] Exception in thread "main" java.lang.NoClassDefFoundError

Jj5 — Mon, 21 Jul 2014 16:43:40 GMT

Resolved: Talend isn't creating a folder that contains the lib directory and the jobinfo properties. I had to put them in the directory manually, but it works now.
I'm trying to build a Standalone job in Talend.
When I run the job in TOS it runs fine. When I build the job and run it on my machine, it runs without error. However, when I try to run the job on another machine I get the following error:
C:\universe\bin\Talend\LenderJob>java -Xms256M -Xmx1024M -cp ../lib/commons-la

I have made sure that Java is installed on the other machines and that the path is set correctly.
It works on my Windows 7 machine, but it isn't working on the Windows 2008 server edition machine.

Resolved: Talend isn't creating a folder that contains the lib directory and the jobinfo properties. I had to put them in the directory manually, but it works now.

Talend generates a zip package while exporting the job script. The zip package should contains a lib direcotry and jobinfo properties file, it is not normal if it doesn't.
Can you please give us more information about this issue? What's the configurations when you export the job script?
Best regards

Hello,
I have the same problem when i create a autonomous Job. My job is working on my Windows 7 machine but not on my Windows 2008 server edition machine.
The error is the same (Exception in thread "main" java.lang.NoClassDefFoundError: routines/system/api/T
alendJob). For information, I am working with Talend 5.5.1.
Is there a solution?
Laurent

Start from the beginning in java when we using some function which belong to some class of jar and we do not have that in our running environment this error happens.

Now when come to talend job which is made in java so this error(which by the way your own fault) happen as when we created different type of jobs like on using excel file to map in mysql db, one using a mysql(any db) and joining it with excel file data to map in mysql(any db) will have different jar file requirement.Means not all talend jobs are using same jar file of lib.

So, check job lib folder jar files if they already exists in global lib folder(of talend) in external project of your.Like in my case

talend_Jobs

/Students

/Teachers

/lib

/jobInfo.properties

I added Schools job here which using some jar file which are not already there in /lib so I added jar files from Schools job /lib to global /lib of talend_Jobs

This is working fine in DEV and after promoting to QA or PROD then jobs failed with this reason. Any idea?

Java is good.

Context params are good.

Job is promoted using promotion option in TMC.
