1、在http://www.sysdeo.com/eclipse/tomcatplugin下载tomcatpluginv31，这里要注意，虽然eclipse是3.2，但tomcatpluginv31是final版，在主页上并没有说明支持eclipse 3.2，但没有更新的版本，我就用了，事实证明可以用。
2、将tomcatpluginV31解压到eclipse/plugins目录下，出现com.sysdeo.eclipse.tomcat_3.1.0子目录。
3、设置eclipse。选择Window->Preferences，在tomcat分支中，版本选择tomcat5.x，Tomcat home选择tomcat安装路径。在tomcat->advanced分支中，tomcat base设置为tomcat安装路径。在JVM Settings中，Classpath选项右边的Jar/Zip，浏览选择JAVA_HOME/lib/tools.jar，否则不能编译jsp。在Tomcat Manager App输入username和password。
4、从eclipse的工具栏按钮中启动tomcat。得到如下提示：
2006-9-20 21:46:02 org.apache.catalina.startup.Catalina load
警告: Can't load server.xml from /usr/local/apache-tomcat-5.5.17/conf/server.xml

5、查看$CATLINA_HOME/conf/server.xml，root用户具有读写权限，其他用户无任何权限，chmod o+r server.xml，添加读权限。
6、再次在工具栏中启动tomcat，得到如下提示。启动成功。注意，受blog字数限制，删除部分内容。
