Report Preview in eclipse does not work [message #826096]

Hi, I know there are many topics along this line, but I have not been able to find one that addresses my issue.

I create a new Report Project and then a new Report, add Data Source (Classic Models Inc. Sample Database), add Data Set with customer info (Data Set Preview Results DOES show data for the query). I then add fields from the Data Set to the Report and select Preview. The Preview page is blank, even the title of the report and the table headings DO NOT show up.

If I select the preview icon at the top and choose "View Report in Web Viewer" the BIRT Report Viewer does launch, it shows the controls and says "Showing page 1 of", but the Report section is blank.

However, if I select the Preview icon and choose "View Report as HTML" the report DOES load in the BIRT Report Viewer.

Here is my configuration:
CentOS 6.2 32-bit
All GCJ and OpenJDK uninstalled
Oracle JDK 6u31 (also tried with 7u3)
Eclipse 3.7.2 for Java Developers (added BIRT through "Install New Software...")
- Also tried with BIRT All-In-One for Linux and the Eclipse Reporting release
Firefox 10.0.3 (also tried 11.0)

I get no error messages, only this on the console where eclipse was started:

** (Eclipse:21340): DEBUG: NP_Initialize
** (Eclipse:21340): DEBUG: NP_Initialize succeeded
** (Eclipse:21340): DEBUG: NP_Initialize
** (Eclipse:21340): DEBUG: NP_Initialize succeeded

** (Eclipse:21340): DEBUG: NP_Initialize
** (Eclipse:21340): DEBUG: NP_Initialize succeeded

I didn't know if that was related but to rule it out, I uninstalled nspluginwrapper 1.3.0 and installed version 1.4.4 from source. The above warning went away but my problem persists.

I had a web proxy set and SELinux is enabled by default, I disabled both of those just in case and it made no difference.

NOTE: If I do everything listed above on Fedora 16 64-bit, it all works fine. So there must be something about my CentOS 6.2 configuration that is not right.

Where else can I look to troubleshoot this? Any logging that I can enable, etc.? Thank you for your time!

Can you open a bugzilla entry for this?
Have you tried to deploy the viewer web app on tomcat to the same machine?

I want to try to investigate this further, but I need a little help with what to do next. Which plugin is responsible for the Preview functionality? Is it org.eclipse.birt.report.designer.ui.preview.web? Or org.eclipse.birt.report.viewer? The latter has a directory called birt/logs, but there is only one file containing the text "The default directory to place BIRT runtime log files.".

Can I enable logging or debugging for these plugins? I suppose I can download the BIRT source and try to export my own plugins, or see what is available in terms of Debug configuration for the Product.

I am also downloading the 4.2.0M6 build to see if the error still occurs there.

Any other suggestions?

Thanks,
Zach

The report.viewer plugin is responsible for previewing the report. You
could check just that plugin in out and debug it.

Hello!

I have the same problem: for empty report (it title only has) preview show progress bar and no more. Browser preview doesn't working too.

But there is one difference: When I run this project on my virtual machine (virtual box, windows xp sp3 rus, java 1.6.0_31-b05) then I see this situation. But the same copy of BIRT all-in-one installation running on my host PC working well. A see test report in preview without any problem!

Could you help me find sources of this difference? I am newbie in eclipse and will be gratefully for any resources how to start my investigation.

I found "debug report" button and press it:) The following log was happens in console:

29.03.2012 15:17:26 org.eclipse.birt.report.debug.internal.core.vm.ReportVMServer start
INFO: [Server] client accepted
29.03.2012 15:17:26 org.eclipse.birt.report.debug.internal.core.vm.ReportVMServer$1 run

INFO: User class path received: 
29.03.2012 15:17:27 org.eclipse.birt.report.debug.internal.core.vm.ReportVMServer$1 run
WARNING: [Server] client disconnected

Then I switch to "debug" perspective and set "open generated file.." flag for html output. After "debug report" starting no additional changes in result was happened. Then I download and install jre7. All previous actions for debugging was repeated. And wonderful: html report was demonstrated!

unfortunately, preview in eclipse hangs as before:(

I make one new version of virtual PC and reinstall all software. And now my BIRT preview working well! I can see preview of any report in eclipse.

P.S. If you are interesting then one feature I found: Data source for ODBC must be system DNS, no user.
