Error filterStart error resolution

Error filterStart error resolution

The project configured in eclipse before the holiday can’t be used after the holiday. I’m at a loss. The problem is that I don’t know what went wrong. Error when starting Tomcat in Eclipse:

Serious: error filterStart
2009-2-4 11:56:58 org. Apache. Catalina. Core. Standardcontext start
serious: context startup failed due to previous errors

I have searched the data for a whole morning and tried many methods to solve it

Method 1: copy Commons digester.jar and Commons beanutils.jar in the directory of Tom/server/lib to the directory of common/lib /

Method 2:

C:/> CD home directory/Web inf/classes

C:/> Jar CVF filters. Jar filters

form the filters. Jar file, put it under Tomcat/common/lib, and restart Tomcat

The final solution is to add tomcat5. 0 to Tomcat 6 (or 5.5), the problem is solved

The following is the error message after tomcat6.0 is installed:
2008-1-15 11:10:57 org. Apache. Catalina. Startup. Hostconfig deploydirectory
serious: error deploying web application directory juncsoft
java. Lang. unsupported classversion error: bad version number in. Class file
at Java. Lang. classloader. Defineclass1 (native method)
the following is the error message after tomcat6.0 is installed At java.lang.classloader.defineclass (unknown source)
at java.security.secureclassloader.defineclass (unknown source)
the original program has been recompiled by eclipse, and jre6.0 is used in compilation, so it is inconsistent with the version (5.0) required by Tomcat (5.5). Correction method: in eclipse window — > Java — > In installed jres, select JDK version 5.0 to recompile the program. Then restart tomcat, the annoying error filterStart finally disappeared, and see the familiar program interface
