The perform method still exists, but the execute method is preferred........
Tomcat 5.5 requires Java 1.5 aka Java5.0 -----Original Message----- From: David G.

The application runs perfectly under Tomcat 4, but when I try to deploy it under version 5, I get the following in catalina.out: ------------------------------------------------------ Nov 17, 2004 2:55:45 PM org.apache.coyote.http11.Http11Protocol init ...

There is no root-cause exception stack trace, no output in other files, etc. * I have been able to get a basic "hello world"-type application to deploy, so I'm pretty sure that Tomcat 5 is working in a sane manner, and that I'm not doing anything incredibly wrong in terms of server configuration. * In WEB-INF/web.xml: <servlet> <servlet-name>action</servlet-name> <servlet-class>d4.pcs.ServletPcsAction</servlet-class> <init-param> ... * The application in question extends the default struts servlet: public final class ServletPcsAction extends org.apache.struts.action.ActionServlet { .... } This class has not changed at all, and works fine under TC 4. There are numerous logging statements in this class, but no log statements show up anywhere. All I get is catalina.out. * I am running on RH 9.0, and have exported LD_ASSUME_KERNEL=2.4.1 as part of starting Tomcat. * (TC 5.5) $TOMCAT_HOME/common/lib/ has the following jar files: commons-el.jar jasper-compiler.jar jasper-compiler-jdt.jar jasper-runtime.jar jsp-api.jar mysql-jdbc-conn.jar naming-factory-dbcp.jar naming-factory.jar naming-resources.jar servlet-api.jar * These classfile folders are all empty: $TOMCAT_HOME/shared/lib/, .../shared/classes/, .../common/classes/. * The application was written using struts 1.0. I have tried putting in the latest Struts jars / tld files (1.2), etc. to no effect. Does anyone perhaps have an idea as to where I might look next?
