今天装了Lomboz＋Tomcat，却碰到了

这个问题，在网上找到了答案：
I edited the file "tomcat50x.server" under
C:\eclipse\plugins\com.objectlearn.jdt.j2ee_3.0.1\servers
and changed
-Djava.endorsed.dirs="${serverRootDirectory}/bin;${serverRootDirectory}/common/endorsed"
to
-Djava.endorsed.dirs="${serverRootDirectory}/common/endorsed"
in the following 'tags':
<startVmParameters>-DJAVA_HOME="${jrePath}" -Dcatalina.base="${serverRootDirectory}" -Dcatalina.home="${serverRootDirectory}" -Djava.io.tmpdir="${serverRootDirectory}/temp" -Djava.endorsed.dirs="${serverRootDirectory}/bin;${serverRootDirectory}/common/endorsed"</startVmParameters>
and
<stopVmParameters>-DJAVA_HOME="${jrePath}" -Dcatalina.base="${serverRootDirectory}" -Dcatalina.home="${serverRootDirectory}" -Djava.io.tmpdir="${serverRootDirectory}/temp" -Djava.endorsed.dirs="${serverRootDirectory}/bin;${serverRootDirectory}/common/endorsed"</stopVmParameters>
This matches the value used in my catalina.bat file when lauched from the command prompt.
原来是Lomboz的配置问题，看来不太支持新版的Tomcat
