[resolved] Large object context variables to tRunjob

Anonymous — Wed, 11 Dec 2013 16:52:12 GMT

I'm having an issue passing an object context variable to a subjob.
The variable is set in the tJavaFlex like so,

context.parentObj = dbu.getObj();

then I'm checking it to make sure it was set.
After the first iteration I'm getting this:

Exception in thread "main" java.lang.Error: java.lang.Error: java.lang.StackOverflowError

So then, what can be done? I've already tried increasing the JVM memory settings for the job. I don't think memory should be this tight grabbing just one object from the database. The only time I see the issue is passing it through to another Runjob.

I ended up making a singleton class in a Talend routine to hold the Object.
