Anonymous — Wed, 29 Jul 2015 13:55:22 GMT

Are you using an Enterprise Edition version of Talend? It looks like this is to do with the JobScript tab (bottom left corner of the workspace). This is a script representation of the job. You can actually use it to make quick and easy copies of jobs and use it to make changes (but only if you know what you are doing). I am guessing that this could be an as yet undiscovered bug as it appears to suggest that this script is null.
I'd try and Talend restart and then raise this with Talend if it continues.

This looks like a potential bug with Talend V6. I intend to download v6 DI tonight. I will see if I get the same issue

Hi dihonore,
Would you mind giving some additional details like: java version, OS, 64-bit/32-bit.
Was your Job working fine in a previous version of TOS? If so, how did you import it? What were you trying to do ?
Cheers
Elisa

Hi dihonore,
Did you point it to the JDK folder instead of JRE folder under Talend Window -> Preferences - > Java -> Installed JREs ->?
Please take a look at KB article about:TalendHelpCenter:Requiring a JDK installation to build jobs starting from version 6.0

Best regards

I tried the 2 paths : "C:\Program Files\Java\jdk1.8.0_51" and "C:\Program Files\Java\jre1.8.0_51".

Same problem : impossible to build a standalone job !

Interesting. I cannot build a standalone job either with V6. I don't get that error message, but nothing is produced. I am using the 1.7 JDK at the moment and not the 1.8 version.

Re: java.lang.NullPointerException when building job

Anonymous — Thu, 30 Jul 2015 11:57:07 GMT

@foquintess: could you try to set it "C:\Program Files\Java\jdk1.8.0_51 \jre"
@rhall: can you add \jre at the end of the java path.
It seems that we could reproduce this pb and solved it with that workaround, but I want to make sure this is the same issue.
Cheers

Thanks Elisa. That sorted it. I didn't experience any other problems with running the jobs inside the Studio. This only affected me when i tried to build a Standalone job. I only tried that to see if this problem affected me.

I used the prefered path C:\Program Files\Java\jdk1.8.0_51\jre but no change appeared.
Impossible to build a standalone job.

FYI : system used : ms windows server 2008 standard sp1
I've noticed that when TOS has been launching a message wrote :
"A JDK is required to build jobs.
You can define which JDK to use in Window prefereces>...>installed JREs."
while setting classpath container : Loading org.talend.repository.items.importexport.ui.

@foquintess: have you restarted your Studio before trying again to build your standalone job?
@rhall: you confirm this workaround fixed the "building standalone job" issue, right? (with JDK v7 for you).

Yes Elisa, I am now able to produce Standalone jobs using JDK 1.7.

Hello,
the problem is logged here: https://jira.talendforge.org/browse/ TDI-33318
Happens when use the checkbox "unzip" after build a job.
Means you can simply avoid to use this option unzip, then everything will be ok.
