问题描述
I have a java file(MyFile.java) which is created in Eclipse on my local machine, the compiled class file is placed in client's linux machine under WEB-INF/classes folder im trying to execute the .class file from linux, im getting Exception in thread "main" java.lang.NoClassDefFoundError: i have set PATH,JAVA_HOME & CLASSPATH. 
我有一个Java文件（MyFile.java），它是在本地计算机上的Eclipse中创建的，已编译的类文件放在客户端的Linux机器中的WEB-INF / classes文件夹下，我试图从linux执行.class文件，线程“主”中的异常java.lang.NoClassDefFoundError：我已设置PATH，JAVA_HOME和CLASSPATH。 The classpath is set as : export CLASSPATH=WEB-INF/classes/:WEB-INF/lib 类路径设置为：export CLASSPATH = WEB-INF / classes /：WEB-INF / lib
I have added lib folder to classpath because im using a .so file which is used by my java class. 我已经将lib文件夹添加到类路径中，因为即时消息使用的是我的Java类使用的.so文件。
Could anyone please help me how to sort out this? 谁能帮我解决这个问题？

Thanks for the responses. 感谢您的答复。 I found the solution to my problem, i did not set CLASSPATH variable instead while running i used -cp and set the class path & lib files used & also set LD_LIBARY_PATH and included along with cp. 我找到了解决问题的方法，我在运行时未设置CLASSPATH变量，而是使用-cp并设置了使用的类路径和lib文件，还设置了LD_LIBARY_PATH并与cp一起包括在内。 I did cd till WEB-INF and executed the following command: java -cp ./lib:./classes:$LD_LIBRARY com/abc/sys/MyFile 我一直执行CD直到WEB-INF并执行以下命令：java -cp ./lib:./classes:$LD_LIBRARY com / abc / sys / MyFile
