Hi Arvind
I am good, How are you ?
Yes I can see the jar files that are created in my application in pr_engineclasses
But the depended jar entries in pr_engineclasses have pzclass has jar file name, but the package details are null.
And because of these the classes in depended jar are not accessible

When I ran the standalone jars they are working on any system with Java comiler.
I think pega is not extracting these dependent jars.
May be there is a way to tell pega to extract them.
Is there are a way to import multiple jars? That way I can import all the dependent jar at once.
P.S
I have imported my jar files into application ruleset, in latest version

in general, you need to be careful when importing a lot of custom jars as they can easily conflict with some OOTB jars. I would recommend include your jars in the app server classpath as the first option. What is your app server?

first option: reference the jars at the app server level - clean no conflict with pega OOTB jars.
second option: import jars into pega database, sometime this can cause class conflict pending on what jars are imported.
future: introduce namespace for class loading so that no conflict happens - this can be an enhancement request if not already filed.

don't think so. The first option is standard practice for all app servers (Websphere, shared lib; jboss eap use custom modules, etc). If you need detailed help, create a SR with GCS. Someone can walk you through step-by-step.

Thanks for the reply, If I choose second option, I need to upload 357 jar files.
Is there any way to upload them at one go?
If nothing works will go for first option by raising a SR

check this link: Re: Importing multiple ruleset zip files to multiple db environments using prpcUtils scripts
But I am curious why you need to import so many jars into pega, the chances are some of your jars will be conflicting with pega. You should also use a unique codeset name so that if something is wrong (you could break some OOTB functionality in the worst case scenario) so that you can delete those jars with certainty. To use your own code set, need to create a DSS:

Cool .
Actually it is a bigger application by itself, So the depended jars sums up to 357.
Will it be ok to use the application ruleset for the import instead of default Customer.?
If any thing goes wrong will delete the corresponding rulesetversion

that is exactly what I suggested. As a side note, you may want to reconsider your design approach how to integrate pega with your java applications. Do they have to be so tightly coupled with pega, considering using REST service to expose some of the features from your applications if possible. I do not know your specific use cases, but want to bring it up and a thought for your team.

Seems good to deploy my application separately and then use rest service to connect to it from pega. Will share with my team.
Is there a way to move the jarof pr_engineclasses to other environment ? Like we do rulesetversion export/import? How?
