Java PDK program got problem from EP6 SP1 to EP6 SP12

Dear Friend,

We upgrade EP platform from EP6 SP1 to EP6 SP12, when the customized Java PDK programs(.par) be imported to the new platform, some are workable, but some are not.

I have two questions:

(1) Are there any docuemnts I can find for my situation?

(2) One of the programs is very strange, when I run the function, it displays a blank screen, no error message can find from the error log. Do you have any idea for my problem?

Thank you.
