topic Could not find or load main class after changing component. in Talend Studio

Could not find or load main class after changing component.

Anonymous — Thu, 08 Mar 2018 06:27:12 GMT

My talend build version is 6.5.1, it is installed in my RHEL7 VM. Also I am using java jdk 1.8.0.

I have a simple job that read data from db2 table then write data to another db2 table in the same database.

I set the tDB2Output "Action on table" option as "Truncate table" initially, it runs fine. But then I have changed the "Action on table" to other options and run the job, it shows

"Error: Could not find or load main class myproject.myjob_0_1.myjob"

Hello,

Does this issue only repro your specific job or all jobs in V 6.5.1 studio?

Problem resolved.

On the right top corner, i can selected "Java" mode, i found that there is problem with my db2jcc_license_cu-6.0.0.jar driver, it says it is cannot be read or is not an invalid zip file. I have downloaded the db2jcc_license_cu.jar and replace the old one, the error disappeared.
