無法從客戶端進行JAX-RPC Web服務調用

Question

我正在使用Jboss 5.0.1服務器並嘗試對我們的應用程序中的一個EJB進行Web服務JAX-RPC調用。 我下載並將以下三個jar從JBOSS_HOME\\server\\default\\lib復制到JBOSS_HOME\\lib\\endorsed

• JBoss的，沒有jaxrpc.jar
• 的jboss-jaxws.jar
• JBoss的，沒有saaj.jar

當拋出此異常時，我無法進行Web服務客戶端調用：

我不知道可能是什么問題，請幫幫我客戶端代碼如下：

<%@page import="java.util.Hashtable"%>   
<%@page import="javax.naming.*,com.test.*,javax.xml.rpc.*,stub.*"%>
<%@page contentType="text/html" pageEncoding="UTF-8"%>                                              
<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>JSP
Page</title></head><body>
             <h1>Hello World!</h1>
             <%
              try{
                 InitialContext ic = new InitialContext( );
                  CarrierWS service = (CarrierWS)ic.lookup("java:comp/env/service/CarrierWS");            
                  out.println("======================="+service.getCarrierWSSEIPort().checkPlanData("2007-01-01"));

              }
              catch(Exception e)
                                {
                   out.println("Exception occurred : " + e.getMessage());
                    e.printStackTrace();
                } 
                 %>
               </body>
           </html>

Answer 1

您是否正確配置了endpoint ？

EndpointInfo.lowerCaseProtocol方法的內容表明你錯了。

private String lowerCaseProtocol(String targetAddress) {
    int colonIndex = targetAddress.indexOf(':');
    String lowerCasedProtocol = targetAddress.substring(0, colonIndex).toLowerCase();
    return lowerCasedProtocol + targetAddress.substring(colonIndex);
}

在endpoint似乎沒有“：”，這意味着substring方法中的endIndex小於beginIndex ，因此StringIndexOutOfBoundsException

檢查您的配置，然后重試。

Answer 2

你得到的錯誤： StringIndexOutOfBoundsException意味着代碼中的某個地方你試圖獲得一個集合中的項目，但該集合沒有你想要獲得的索引。

所以，例如：

//lets say myList contains 10 items
List myList = new ArrayList();

myList.get(10) // will throw StringIndexOutOfBoundsException since there is no index 10

因為在jsp代碼中我沒有看到任何使用集合，我猜測問題出在服務/ EJB本身。

Answer 3

我遇到了這個問題，問題是我在背書文件夾中復制了錯誤的jars版本。

解決方案是復制

                   jboss-common-core.jar
                   jboss-logging-spi.jar
                   jbossws-native-jaxrpc.jar
                   jbossws-native-jaxws.jar
                   jbossws-native-jaxws-ext.jar
                   jbossws-native-saaj.jar

從\\ client文件夾到背書文件夾。 這解決了我的問題
