i just updated helma and antville on my server, but all i see is "The server encountered an error while processing your request. Please check back later." is this a helma or a tomcat error code? where should i look into first? i tried helma in stand-alone mode and it worked, but i can't get it to run behind that tomcat. any help is appreciated.

make sure you update it to the new version from the Helma lib directory. Then restart Tomcat. BTW, running Tomcat just for Helma is total overkill, because mod_jk can connect directly to Helma (start with -jk option).

a long time ago you simply head to drop the -w switch for using tomcat. what am i supposed to do now? use -jk 8009 or no switch at all? neither option works, though.

i found it. in case anyone still needs it: the secret word was RMI_PORT=5055 as specified in the web.xml inside tomcat/webapps/helma/...

changing to ajp turned out to be not as trivial as i thought because of rewriting rules and virtual hosts and i couldn't be arsed to rtfm.
