本文探讨了Java启动类路径中包含或不包含tools.jar时，对使用JConsole进行内存监控所产生的不同效果。同时提到，如果未设置JAVA_HOME环境变量，则启动JBoss前，Java的类路径将不会包含tools.jar。此外，还简要介绍了tools.jar的主要功能是提供编译Java文件的能力。

      在java的启动类路径中，有和没有tools.jar，在jconsole时监控的内存图形，结果是两样的。真不知道，sun有什么必要这样搞。

      启动jboss前，如果没有设置java_home,则java.class.path中就不会有tools.jar.

      我们知道，tools.jar主要是提供了编译java文件有关的功能。

 场景:  共发布了15个 .war、.jar在JBOSS服务器下,eclipse里配置好JBOSS,并eclipse启动JBOSS。然后在eclipse修改java代码,竟然不用重新发布.war、.jar,也不用重新启动JBOSS,修改的代码竟然生效了. 分析原因: 1、Eclipse(Juno) 的编译部署(目测概率不大)                 2、JBOSS Tools(jb...

1.现象： 在window8下启动一个老项目需要用到jboss4.0.5,启动报错“此时不应有 \Java\jdk1.6.0_21\lib\tools.jar。”。 在网上搜了很多解决办法都不起作用，只能查看run.bat脚本了。 2.解决办法： 修改run.bat文件，将设置JBOSS_CLASSPATH中有关%JAVAC_JAR%的内容注释掉即可，具体如下： 代码片段：
