Possible circular dependency problem with org.adempiere.report.jasper.* plugins

Description

It seems as if JasperReports is not working in iDempiere. When a Jasper report is used for, for instance an Invoice the following error message occurs:

-----------> ProcessUtil.startJavaProcess: org.compiere.report.ReportStarter [13]
java.lang.ClassNotFoundException: org.compiere.report.ReportStarter

Looking at the plugin dependencies the class org.compiere.report.ReportStarter is located in plugin org.adempiere.report.jasper and the org.adempiere.util.ProcessUtil class which is in plugin org.adempiere.base tries to load the ReportStarter class.

If I understand osgi correctly, the base plugin only see the classes of the plugins on which it depends. org.adempiere.base doesn't depend on org.adempiere.report.jasper.

org.adempiere.report.jasper depends on org.adempiere.base so org.adempiere.base can't depend on org.adempiere.report.jasper.

When checking the "legacy report format" I see that the code for that resides in the org.adempiere.base plugin.

The way I see it, some classes must move. Either ProcessUtil moves out of org.adempiere.base or org.adempiere.report.jasper moves into org.adempiere.base.

Any suggestions? Have I understood the problem correct?

Nice work Was it only a dependency in org.adempiere.ui.swing? That was a lot easier solution than mine!

Hi Daniel,

One way is to join iDempiere weekly meeting (Every Wednesday 1PM UTC, room #idempiere on irc.freenode.net) and mention the ticket and fix there. Usually its reviewed and accepted at the same time.

OK, no problem. Is it possible to add states in the workflow that will show that the issue is resolved but not accepted?

Or in other words, how do I best notify that a bug/fix is ready for acceptance testing?

Let me know and I'll document the development process in our wiki

please don't mark issue as resolve until it have been accepted into head, thanks.
