• Business Objects XI3.1 Enterprise
• Weblogic
• Stingray Load balancers
• Highly isolated and secured network with multiple proxy servers.

1. Login into Infoview using Loadbalancer URL
2. Edit a report or select to create new report - receive blank page.
3. Do the same in using direct URL to the app server - see no issue.

Issue did not existed originally, and started suddently with no known changes done to the environment.

The issue is caused by the fact that the original AnalyticalReporting.ear was changed to AnalyticalReporting.war during upgrade to latest patch.
Wrong application was deployed and it has prevented various proxies from allowing access to the jar files needed for report creation/editing functionality.

Java Report Jar files were not properly downloading to the client machines.

Properly prepare all BOE web applications using instructions from Web Applications deployment guide.
In case of Weblogic, deploy ear files generated by the wdeploy tool.

When using proxies - make sure they are allowing jar files download to client machines.
