Exception in thread "main" java.lang.LinkageError:

调用外部接口,通过myeclipse--web server client 一系列操作,得到一些文件,然后写测试demo,
public static void main(String[] args) {
// TODO Auto-generated method stub
EntpriseInfoImplService ent = new EntpriseInfoImplService();
EntpriseInfoInterface eif = ent.getEntpriseInfoImplPort();
String info=eif.findEnt(1, 2, "");
//eif.findEnt(0, 10, "");
System.out.println(info);
//System.out.println(System.getProperty("java.endorsed.dirs"));

}
