Linux下的classpath怎么配置 - linux报错

export JAVA_HOME=/ys/up/jdk1.7.0_25
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$JAVA_HOME/bin:$CATALINA_HOME/bin:$PATH

上面是现在/etc/profile里面的配置

Exception in thread "main" java.lang.NoClassDefFoundError: LTServer (wrong name: com/lt/LTServer)

要怎么配置才能用java命令执行class文件？()

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar 

这种好像也不行..
