Subject [jira] [Comment Edited] (SYNAPSE-932) Class Loading issue in Script Mediator
Date Wed, 24 Apr 2013 12:35:16 GMT

    [ https://issues.apache.org/jira/browse/SYNAPSE-932?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13640382#comment-13640382

--------------------------------------------------------------------

Reason for the issue is external dependencies inside 'template/lib'  are not visible for the
Rhino engine (because it loads with the default Rhino context). So fixed it by setting up
class loader specifically for Rhino engine context, within script mediator. Attaching patch
Please review & commit.(Apply the patch to https://svn.apache.org/repos/asf/synapse/trunk/java/modules/extensions)


Thanks,
