java命令行运行

Question

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
[code="java"]Exception in thread "main" java.lang.NoClassDefFoundError: Tester

怎样在运行时包含comm.jar?

Answer 1

[quote]-bash: commapi/jar/comm.jar: cannot execute binary file [/quote]
commapi/jar/comm.jar 不是可执行的文件。

你是运行它了吧？
