解決方案：

下載jboss-5.1.0.GA-jdk6，並將JBOSS_HOME\lib\endorsed下的幾個以Jboss開頭的jar包分別複製到JAVA_HOME\lib\endorsed 和 JRE_HOME\lib\endorsed目錄下。兩個lib目錄中可能都沒有endorsed檔案夾（反正我的沒有），那就自己建立一個。

需要複製的jar包：

jbossws-native-jaxrpc.jar
jbossws-native-jaxws.jar
jbossws-native-jaxws-ext.jar
jbossws-native-saaj.jar

注意：從eclipse啟Jboss需要在jre下放置這些包，從外部啟Jboss需要在jdk下放置上面的jar包。
開始只注意到用戶端報的錯誤，於是根據錯誤資訊就在網上搜尋解決辦法，可是找到的資料千奇百怪，說什麼的都有。後來賈琳一句話提醒了我，他問我Jboss報什麼錯誤，這時我才想起來還有Jboss的事呢。後來他把他之前遇到類似錯誤的部落格發給我，我按照上面的辦法弄了弄，不過還是發現有點小問題（從外部啟Jboss還是報錯）。後來參考一篇網友的部落格解決了這個問題。這篇文章很詳細的講解了出現這個錯誤的原因，有興趣的朋友可以看看。
