Hi
Which OS?
Please check whether you have spaces in your talend installation path(i.e c:\TOS 4.2.3).
If yes, reinstall in a path with no space.

Pedro

Hi
Have you fixed the below error?

java.lang.NoClassDefFoundError: talenddemosjava/testjob_0_1/TestJob

Could you show me the code of tJavaFlex?
Do you import slf4j jar correctly?
Regards,
Pedro

public void tJavaFlex_1_error(Exception exception, String errorComponent,
final java.util.Map<String, Object> globalMap)
throws TalendException {
end_Hash.put("tJavaFlex_1", System.currentTimeMillis());
tJavaFlex_1_onSubJobError(exception, errorComponent, globalMap);

If I run other Job in my Talend Open Studio also I am getting the Same Issue :

Hi
According to what you say, you'd better delete TOS file and unzip (using 7-Zip) the zip file back into D:\TOS-All-r63143-V4.2.2.
If errors still occur, please report bug at BugTracker.
Regards,
Pedro

Hi
Yes. I'm sure this error is not related to slf4j jar.
Maybe the TOS files are corrupted.
Unzip TOS with 7-zip. Or you may encounter NoClassDefFoundError again.

Pedro

This can also happen if you install Talend to a directory containing a space (e.g. "Program Files") if you Talend installed in a directory containing a space, try moving it to one that does not contain a space.
