带你走进EJB--将EJB发布为Webservice(3)

? ?

? ? 在上面文章中我们讲到,通过使用用JBoss5作为EJB容器的时候，调用Web服务出现了异常. 异常信息如下:

Iread the release notes for Jboss as 4.2.3.GA and it describes what to do ifrunning webservies using jdk1.6. Here is what helped me: (taken from therelease notes and followed exactly as printed)

?

*JBossAS 4.2.3.GA can be compiled with both Java5 & Java6. The Java5compiled binary is our primary/recommended

binarydistribution. It has undergone rigorous testing and can run under both a Java 5and a Java 6 runtime. When

runningunder Java 6 you need to manually copy the following libraries from theJBOSS_HOME/client directory to

theJBOSS_HOME/lib/endorsed directory,so that the JAX-WS 2.0 apis supported byJBossWS are used:

????????? o jboss-jaxrpc.jar

????????? o jboss-jaxws.jar

????????? o jboss-jaxws-ext.jar

????????? o jboss-saaj.jar

?

??????解决方法是把JBoss4.2内的JBOSS_HOME/client目录下的一下文件复制到JBoss5.1内的JBOSS_HOME/lib/endorsed目录下，重启服务就可以了。

jboss-jaxrpc.jar

jboss-jaxws.jar

jboss-jaxws-ext.jar

jboss-saaj.jar

?

???????出现的问题跟版本有关系.到此我们基本上能够使用EJB发布WebService服务,并且能够调用简单参数的WebService.但是如果想让客户端调用复杂一些的参数呢?比如一个实体.下一篇文章将会调用复杂的参数.
