Exception in thread "main" java.lang.LinkageError错误的解决
来源:互联网 发布:富士康机器人编程软件 编辑:程序博客网 时间:2024/05/19 10:07
在用myeclipse进行调试代码的时候,我们经常在java文件中加入main方法来进行调试。那么有时候会因为包兼容的问题引发以下错误,导致调试失败:
**************************************************************
Exception in thread "main" java.lang.LinkageError: JAXB 2.0 API is being loaded from the bootstrap classloader, but this RI (from jar:file:/D:/workspace/A8_Common/webapp/WEB-INF/lib/jaxb-impl.jar!/com/sun/xml/bind/v2/model/impl/ModelBuilder.class) needs 2.1 API. Use the endorsed directory mechanism to place jaxb-api.jar in the bootstrap classloader. (See http://java.sun.com/j2se/1.5.0/docs/guide/standards/)
**************************************************************
解决办法如下:首先在main函数中输出兼容包的目录所在:
System.out.println(System.getProperty("java.endorsed.dirs"));
我的路径为:C:\Program Files\Java\jdk1.6.0\jre\lib\endorsed
然后到这个目录的上层(这里为lib目录)建立endorsed文件夹,拷贝文件jaxb-api.jar到endorsed文件夹,OK搞定
