Resolution:
Yes, XML Canon can run under JRE 1.5. In order for XML Canon to run under JRE 1.5.0, you MUST modify the startup scripts to use JRE 1.5.0 and then restart the XML Canon service. By default, the XML Canon startup scripts point to JRE 1.4.2. Replace the default JRE with JRE 1.5.0 in all paths within the script is all that is required for the XML Canon server to run under JRE 1.5.0.

On Unix/Linux, this means modifying the files /tibco_home/xmlcanon/3.1/tomcat/bin/xmlcanon.sh and /tibco_home/xmlcanon/3.1/tomcat/bin/xmlcanon.tra by replacing JRE 1.4.2 with 1.5.0 where JRE 1.4.2 appears in all paths.

On Windows, this means modifying \tibco_home\xmlcanon\3.1\tomcat\bin\xmlcanon.tra and the Windows registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\xmlcanon\Parameters by replacing JRE 1.4.2 with 1.5.0 where JRE 1.4.2 appears in all paths. (Warning: Modifying the Windows registry without exercising caution could have undesirable consequences on your system; therefore, we recommend that you backup your registry before any modifications.)
