菜鸟调错（三）——Jboss与jdk版本不兼容导致WebService调用出错

环境：

jdk1.6

Jboss 5.1.0.GA

问题描述：

EJB发布webserivce已经成功，并且能够成功访问wsdl文件；
使用axis1自带的sample/client下的类DynamicInvoker测试，程序报错。

错误信息：

客户端：

解决方案：

下载jboss-5.1.0.GA-jdk6，并将JBOSS_HOME\lib\endorsed下的几个以Jboss开头的jar包分别复制到JAVA_HOME\lib\endorsed 和 JRE_HOME\lib\endorsed目录下。两个lib目录中可能都没有endorsed文件夹（反正我的没有），那就自己新建一个。

需要复制的jar包：

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

注意：从eclipse启Jboss需要在jre下放置这些包，从外部启Jboss需要在jdk下放置上面的jar包。

开始只注意到客户端报的错误，于是根据错误信息就在网上搜寻解决办法，可是找到的资料千奇百怪，说什么的都有。后来贾琳一句话提醒了我，他问我Jboss报什么错误，这时我才想起来还有Jboss的事呢。后来他把他之前遇到类似错误的博客发给我，我按照上面的办法弄了弄，不过还是发现有点小问题（从外部启Jboss还是报错）。后来参考一篇网友的博客解决了这个问题。这篇文章很详细的讲解了出现这个错误的原因，有兴趣的朋友可以看看。
