java命令行运行5

javac -cp ./jcomm/comm.jar Tester.java可以编译，但是运行
java -cp ./jcomm/comm.jar Tester就报如下错误，Tester运行需要comm.jar

Exception in thread "main" java.lang.NoClassDefFoundError: Tester
Caused by: java.lang.ClassNotFoundException: Tester
        at java.net.URLClassLoader$1.run(URLClassLoader.java:200)

怎样在运行时包含comm.jar?

问题补充：javac可以运行没有错误，在运行java时出现错误~

问题补充：另外我编写了一个简单的Tester01，运行java Tester01可以
随便来个jar包放到该目录下，运行
java -cp XXX.jar Tester01也会报上面的错误

问题补充：没有加包名，我试一下价格包名的结果

问题补充：建了个tt文件夹，Tester.java（只剩下System.out.println了，不用依赖jar包了）里面也加了package tt;把Tester放到tt里,编译面，
运行结果如下，直接java java tt.Tester可以，加个-cp xxx.jar就出错：
[aimc4@cudev133 jcomm]$ java tt.Tester
*****haha*******
[aimc4@cudev133 jcomm]$ java -cp ant165.jar tt.Tester
Exception in thread "main" java.lang.NoClassDefFoundError: tt/Tester

[aimc4@cudev133 jcomm]$

问题补充：原先问题解决了
出现这个情况：

-bash: commapi/jar/comm.jar: cannot execute binary file

问题补充：只是执行了
java -cp .;ant165.jar tt.Tester

而已，错误变成了java命令的介绍，还有最后一句
