Subject Re: Tomcat, Apache: JSP source code showed instead of generated HTML
Date Wed, 29 Aug 2001 16:48:22 GMT
OK, I cracked up the debug level and now mod_jk.log contains more info 
(see attacheement). The strange thing I notice is that is seems to try 
to execute everything twice. Does this ring a bel with anybody?

The jasper.log file does not contain much more info:

2001-08-29 18:29:15 - Parent class loader is: AdaptiveClassLoader(  )
2001-08-29 18:29:15 - Scratch dir for the JSP engine is: 
/opt/jakarta-tomcat-3.2.3/work/localhost_8080%2Fexamples
2001-08-29 18:29:15 - IMPORTANT: Do not modify the generated servlets
2001-08-29 18:29:15 - Parent class loader is: AdaptiveClassLoader(  )
2001-08-29 18:29:15 - Parent class loader is: AdaptiveClassLoader(  )
2001-08-29 18:29:15 - Parent class loader is: AdaptiveClassLoader(  )


Any ideas?

Gero
