本文介绍了Cordys系统中出现的IllegalArgumentException异常原因及其解决方法。通过调整WebService后端代码中的SQL查询语句使其与base类中定义的表名保持一致，解决了localizableString不能为null的问题。

<cordys:FaultRelatedException xmlns:cordys="http://schemas.cordys.com/General/1.0/">
    <![CDATA[java.lang.IllegalArgumentException: localizableString cannot be null

对比WebService后端代码：
public static BusObjectIterator<com.davidwsappserverpackage.upload> GetUpLoadByLeavingID(String LeavingID)
{
	String queryText = "select * from UpLoad where leavingID=:leavingID";
	QueryObject query = new QueryObject(queryText);
	query.addParameter("leavingID", "upload.leavingID", QueryObject.PARAM_STRING ,LeavingID);
	query.setResultClass(upload.class);
	return query.getObjects();
}
发现SQL语句中的表操作为大小写混合，跟base类里默认表对象upload小写不一致，导致以上错误，修改为base类一致后正常。

有时候 cordys编译不成功，删除　

C:\Program Files\OpenText\OpenText Cordys\defaultInst\bsf\runtime\deploy\Learning

下面的　jar文件，重新编译
