求大神啊--调用webservice时报错

我用Jsoup解析网页，代码在eclipse上可以成功，但是发布到tomcat上报错了

public String getJWGG() {
     URL getJWGG_url = null;
try {
getJWGG_url = new URL("http://202.203.194.10/jwnews/Default.aspx");
} catch (MalformedURLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
     //获取教务处公告的方法
        String text = "" , title = "" , href = "";
        Document doc = null;
try {
doc = Jsoup.parse(getJWGG_url, 6000);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// 提取table中的文本信息
Elements links = doc.select("table[id=Newnews1_DataList1]");
for (org.jsoup.nodes.Element link : links) {
//提取出地址
    for(org.jsoup.nodes.Element link_address : link.select("a"))
    {
     //获取标题
     title = link_address.attr("title");
     //获取地址
     href = "http://202.203.194.10/jwnews/"+link_address.attr("href");
     text += "<li style=\"list-style:none; border-top:solid #CCC 1px;padding-top:0.5em; margin-bottom:0.5em;\" " +
     "><a href=\"javascript:contact.sendTarget(\\'"+href+"\\')\">"+title+"</a></li>";
    }
}
        return text;
    }

这个方法在eclipse上是可以成功的，但是在服务器上好像红字就报错了，下面是错误信息

我调用的时候显示了这个
