			<content:encoded><![CDATA[<div>今天下午在RedHat linux enterprise5.4上安装tomcat。</div>
<div>最后执行/usr/tomcat/bin/startup.sh启动的时候报，Error occurred during initialization of VM<br />
java/lang/NoClassDefFoundError: java/lang/Object</div>
<div>
在网上寻找到原因为: /usr/lib/jdk1.6.0_17/lib下面的tools.pack需要解压为tools.jar,/usr/lib/jdk1.6.0_17 /jre/下的rt.pack需要解压为rt.jar。不过还好在/usr/lib/jdk1.6.0_17/bin下有一个工具unpack200可以解压。不明白sun为什么搞成这么麻烦？</div>
<div> </div>
<div>网上找的文章贴在下面。</div>
<div>======================================================================</div>
<div>安装完JDK ，设定环境变量后出现这个错误：</div>
<div>[root@localhost lib]# javac<br />
Error occurred during initialization of VM<br />
java/lang/NoClassDefFoundError: java/lang/Object<br />
[root@localhost lib]# java<br />
Error occurred during initialization of VM<br />
java/lang/NoClassDefFoundError: java/lang/Object</div>
<div>解决办法：分别把 </div>
<div>/opt/jdk1.6.0_15/lib/ tools.pack  转为  tools.jar  </div>
<div> </div>
<div>/opt/jdk1.6.0_15/jre/lib/rt.pack   转为  rt.jar</div>
<div>[root@localhost lib]# pwd<br />
/opt/jdk1.6.0_15/lib<br />
[root@localhost lib]# unpack200 tools.pack tools.jar<br />
[root@localhost lib]# ls<br />
ct.sym  htmlconverter.jar  jconsole.jar  orb.idl     tools.jar   tools.pack.bak<br />
dt.jar  ir.idl             jexec         sa-jdi.jar  tools.pack  visualvm</div>
<div>[root@localhost lib]# pwd<br />
/opt/jdk1.6.0_15/jre/lib<br />
[root@localhost lib]# unpack200 rt.pack rt.jar</div>
