看来您已经找到了解决方案，但我对同一问题的解决方案有点不同。
在 Eclipse 3.6 中运行 Tomcat 4.1.29，我开始收到非常类似的错误（Servlet /webcustom 抛出 load() 异常 javax.servlet.UnavailableException: Parsing errorprocessing resources path /WEB-INF/conf/struts-config-资源.xml，...）。
执行“Eclipse > Project > Clean”或“Eclipse > Servers > (Tomcat Server Instance) > Clean Tomcat Work Directory”都无法解决我的问题。
然而，经过大量的试验和错误，我发现解决方案是这样的......
Eclipse >服务器> （Tomcat 服务器实例）...
希望这对其他人有帮助。

It looks like you've already found your solution, but my solution to the same problem was a little different.
Running Tomcat 4.1.29 inside Eclipse 3.6, I started receiving a very similar error (Servlet /webcustom threw load() exception javax.servlet.UnavailableException: Parsing error processing resource path /WEB-INF/conf/struts-config-resource.xml,...).
Neither performing an "Eclipse > Project > Clean", nor an "Eclipse > Servers > (Tomcat Server Instance) > Clean Tomcat Work Directory" would resolve the problem for me.
However, after a lot of trial and error, I found the solution to be this...
Eclipse > Servers > (Tomcat Server Instance)...
Hopefully this helps someone else.

下载 commons-logging 并将 jar 放入
WEB-INF/lib.对于未来 - 谷歌找不到的类名，看看它属于哪个库，下载它并将其放在类路径上（在本例中为
WEB-INF/lib）Donwload commons-logging and place the jar(s) in
WEB-INF/lib.And for the future - google the class name that is not found to see which library it belongs to, download it and put it on the classpath (
WEB-INF/libin this case)
