oracle type mapping

[conradi]

hi all,

i have recently begun to play with timers in jboss-4.0.1RC1.
since i use an oracle database, i created an approbriate timer table, changed the ejb-deployer.xml accordingly. i then got an error to do with failed metadata service. after a little digging around i found, that there is a new option in the oracle-ds.xml concerning type mapping and set the typemapping to Oracle9i. Everything seemed to work fine, all tests run, however an attempt to look at the jmx-console produced the following error:

javax.servlet.ServletException: org/apache/jsp/index_jsp (Unsupported major.minor version 49.0)

does anybody know, what is going on here?

an update to my own post ;-(

i had nothing to do with the oracle- or timer related configuration.
it went away, when i used another runtime java-vm.

i do not understand this - but it works.

i guess, it has to do with the java compiler used by tomcat to compile
the jsp-pages.
does anybody know, it this is correct - and how to determine the used
compiler?
