通过$JBOSS_HOME/bin/run.sh启动jboss报错
[root@capitek1 bin]# ./run.sh

  JBoss Bootstrap Environment

  JBOSS_HOME: /usr/local/jboss-5.1.0.GA

  JAVA: /usr/java/jdk1.6.0_14/bin/java

  JAVA_OPTS: -Dprogram.name=run.sh -Xms128m -Xmx512m -XX:MaxPermSize=256m -Dorg.jboss.resolver.warning=true -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Djava.net.preferIPv4Stack=true

  CLASSPATH: /usr/local/jboss-5.1.0.GA/bin/run.jar

Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object
[root@capitek1 bin]#

处理方法如下：
安装完JDK ，设定环境变量后出现这个错误：
[root@localhost lib]# javac
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object
[root@localhost lib]# java
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object

解决办法：分别把 
/opt/jdk1.6.0_15/lib/ tools.pack  转为  tools.jar  
 
/opt/jdk1.6.0_15/jre/lib/rt.pack   转为  rt.jar

[root@localhost lib]# pwd
/opt/jdk1.6.0_15/lib
[root@localhost lib]# unpack200 tools.pack tools.jar
[root@localhost lib]# ls
ct.sym  htmlconverter.jar  jconsole.jar  orb.idl     tools.jar   tools.pack.bak
dt.jar  ir.idl             jexec         sa-jdi.jar  tools.pack  visualvm

[root@localhost lib]# pwd
/opt/jdk1.6.0_15/jre/lib
[root@localhost lib]# unpack200 rt.pack rt.jar

用$JBOSS_HOME的jboss_init_redhat.sh启动同样报错
[root@capitek1 bin]# ./jboss_init_redhat.sh  start
JBOSS_CMD_START = cd /usr/local/jboss-5.1.0.GA/bin; /usr/local/jboss-5.1.0.GA/bin/run.sh -c default
su: user jboss does not exist

JAVA_OPTS="-Xms512m -Xmx1024m -server -XX:MaxPermSize=300m -XX:MaxNewSize=300m -server -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"

jboss启动后的进程情况
[root@capitek1 ~]# ps -ef|grep java

问题：如何得知jboss进程启动正常，jboss日志在哪里？

如何用$JBOSS_HOME/bin/run.sh启动不加&选项，必须要一直开这个窗口，要是强行关闭这个窗口，jboss就会关闭，所以要加上&
