I have a servlet that needs to invoke the class loader. This, of course, causes a SecurityException due to a sealing violation (trying to invoke arbitrary classes). Well, I've tried changing the Catalina security policy file, catalina.policy, so that it grants the appropriate permissions to the servlet. I've also tried granting all permissions to all code. Neither seems to work. Has anyone successfully overcome this problem with Catalina? I'm using yesterday's nightly build of Catalina, FWIW. Thanks. -dan -- Dan Kirkpatrick, Software Architect Blue Lotus Software +44 (0) 1224 575 985 [EMAIL PROTECTED] http://www.bluelotussoftware.com
