org.compiere.report.ReportStarter can't find SwingJRViewerProvider / ZkJRViewerProvider

[Daniel Tamm]

Just downloaded the latest code and I got a wierd problem when trying to view documents defined in JasperReports.

I figured that the plugin-structure has changed a bit with plugins defined in OSGI-INF and all looks fine as far as I can see.

What happens is that the JRViewerProvider can't be found which results in a NPE

I've checked that the plugins are included in the run configuration, I've recompiled and compared configuration for ZK and Swing. I can't see what's wrong.

The service lookup that fails is this piece in ReportStarter:

                   JRViewerProvider viewerLauncher = Service.locator().locate(JRViewerProvider.class).getService();

                   viewerLauncher.openViewer(jasperPrint, pi.getTitle()+" - " + reportPath);

viewerLauncher gets a null value.

I tried also running a report in ZK (server) and it resulted in OutOfMemoryError...

I'm not running Garden World so some custom settings might disturb but I can't think of what it would be.

Best regards

Hi Daniel, precisely researched that a few hours ago, answered here:
http://jira.idempiere.com/browse/IDEMPIERE-28?focusedCommentId=13063&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13063

You must start the following bundle via OSGi console:
org.adempiere.report.jasper.swing_1.0.0.qualifier

Making the bundle start automatically get rid of the error - but I think those must be lazy starters - don't know how to make lazy work.

Thanks for a quick response! What a co-incidence that you researched it just before :-)

I changed the run configuration in eclipse to Default auto-start = true and it worked right away.

Adding

<booleanAttribute key="default_auto_start" value="true"/>

to swingclient.product.launch in org.adempiere.ui.swing-feature would avoid people from running into the problem when running the swing client :-)

Hi Carlos, thanks for answering there.
Lazy start bundle can be configured in manifest.mf. I have tested it and it works now.

Hi Daniel,

I also got OutOfMemoryError in ZK before. You can try to increase the heap size via VM arguments. I don't really know how to tweak it properly, but I added "-Xms512m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=512m" and it works for me.
