EL comes with the Servlet 2.4 spec which is supported in Tomcat 5x. I believe you may be able to get EL like behaviour with the Struts-EL taglib, but you won't get it out of the box on Tomcat 4. Allistair. -Original Message- From: Richard Reyes [mailto:[EMAIL PROTECTED] Sent: 07

Re: Tomcat 5.5.9 and log4j problem

In appears that bin/catalina.sh does not add these directories to the initial classpath. Therefore neither jar file, nor configuration is found during start. Adding common/classes to classpath in catalina.sh and putting the jar files to the jvm lib is one way to solve the problem. Jørgen

I think that's expected behaviour: You can't set headers after the response has been committed (more body data has been written to the outputstream than the buffer size). In the case of the 200 response code the call to filterChain.doFilter(...) actually serves the content. Setting of the
