On our support site we have a document of supported platforms for various Operating systems, including Linux. In the Application server table, it lists the following configurations:
Application Servers                 JDK
[] OAS 10G Rel.2 (10.1.2)      1.4.2_x </p><p align="left">Tomcat 5.0.27                        1.4.2_08+ </p><p align="left">[] WebLogic 8.1 SP4            1.4.2_x </p><p align="left">WebSphere 5.1.0.4                 1.4.1_x </p><p align="left">[**] WebSphere 5.1.1.0        1.4.2_x
WebSphere 6.0.0.2Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 1.4.2_x
I would also suggest reviewing the platforms document
[http://support.businessobjects.com/communityCS/TechnicalPapers/boe_xi_r2_supported_platforms_linux.pdf | http://support.businessobjects.com/communityCS/TechnicalPapers/boe_xi_r2_supported_platforms_linux.pdf]
In your case it would seem that the issue is related to the platform you are trying to deploy on. Â
Usually the solution is to deploy on something that is on the supported list; it is one less thing that gets in the way of a successful solution. One thing you might try, is recompiling the JARS using the newer JDK, this is not a guarunteed solution but has been known to work in the past.Â
I do recommend, as a member of Developer Support, that you have a supported configuration, that way if you find any bugs with the product, we have an escalation path to fixing them.Â
