problem with import in jython postfunction script Jira


I'm trying to migrate from JIRA 4.2.4 to JIRA 6.2.7

Among other problems that I encountered, now it came out another

I have many post function with jython script

I also use JIRA rpc in those scripts

In JIRA 6 rpc plugin is bundled (as difference from 4.2.4 where i had to put it in /lib)

Now my jython script gives me error on import:

/secure/CreateIssueDetails.jspa [jira.plugin.workflow.JythonValidator] Unrecognized exception while executing Jyphon script: null

Traceback (most recent call last):

  File "<string>", line 2, in <module>

ImportError: No module named rpc

    at org.python.core.Py.ImportError(

at line : "from com.atlassian.jira.rpc.soap import JiraSoapService"

The plugin shows that is enabled in JIRA

Please Help me to resolve that import so that my scripts continue to work


Thank you

As I said, this is an OSGi issue. This is not a JSS bug and thus can not be fixed.

To get a Class a class (e.g. DB driver) from a system classloader: 

from com.atlassian.jira.component import ComponentAccessor
drv = ComponentAccessor.getClassLoader().loadClass("org.postgresql.Driver").newInstance()
print drv


To get a class from another OSGi plugin - actually any v2 JIRA plugin - you need to have an access to that plugin classloader. As I said, I do not have a solution for that out of hand.



thanks Alex At least I now know that I have to look in other directions.. you saved me some time thanks again MCTibi
