webservice接口报错 怎么办？鼓捣了一天，没进展，求支招！！！?报错

通过kettle调用接口，根据返回值判断下一步操作流程，恰巧返回值取不到还报错：

这是myeclipse报的错

这是http port 里面的写法

    "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"+"\n"+"<document>"+"\n"+"<employee>"+"\n"+"<id>"+SERIALNUMBER+"</id>"+"\n"+
    "<fromopertype>"+FROMOPERTYPE+"</fromopertype>"+"\n"+
     "<status>"+STATUS+"</status>"+"\n"+"<DM>"+DM+"</DM>"+"\n"+

     +"<telephone>"+TELEPHONE+"</telephone>"+"\n"+"<targetsys>"+SYS_ID+"</targetsys>"+"\n"
       +"</employee>"+"\n"
    +"</document>";

这是发给接口的xml格式的字符串

忙活了一天还没解决，江湖救急，哪位大侠来指点迷津！！！
