ClassNotFoundException axiom-api-1.2.7.jar [英] ClassNotFoundException axiom-api-1.2.7.jar

问题描述

我在Java项目中遇到此异常

I am getting this exception in my java project

Caused by: java.lang.ClassNotFoundException: org.apache.axiom.om.OMDataSource
        at java.net.URLClassLoader$1.run(Unknown Source)
        at java.security.AccessController.doPrivileged(Native Method)

        at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)

我的课程路径是

C:\axiom-impl-1.2.7.jar;C:\axiom-api-1.2.7.jar;C:\axiom-dom-1.2.7.jar;.;

你能帮我吗？

推荐答案

最终设法解决了此问题。问题是jar里面有一个manifest.mf文件，它定义了类路径。我猜这要比命令提示符下java命令中-classpath选项的任何env变量优先。

Finally managed to resolve this issue. The problem was that the jar had a manifest.mf file inside it which defined the classpath. I guess this takes priority over any env variable of the -classpath option in the java command in command prompt.

这是更改
