如何强制jboss从webapp的lib中的jar加载类 [英] How to force jboss to load classes from jars in webapp's lib

问题描述

我正在尝试将Web应用程序部署在当前已部署在apache tomcat上的jboss-6.0.0Final上. 我有两个罐子，其中每个罐子都包含org.apache.axis相同的包装.我要在<Jboss-home>/server/default/lib&中放入一个罐子<my-app-war>WEB-INF/lib中的另一个jar.

I am trying to deploy my web application on jboss-6.0.0Final, which is currently deployed on apache tomcat. I have two jars one that contains same package which is org.apache.axis. I am putting one jar in <Jboss-home>/server/default/lib & another jar in <my-app-war>WEB-INF/lib.

需要将两个jar都放在类路径中.无法删除其中一个罐子.所以我需要两个罐子都放. &它给了我以下错误

It is required to put both jars in the class path. No way to remove one of the jar. So I need to keep both jars. & It is giving me following error

java.lang.ClassCastException: org.apache.axis.attachments.AttachmentsImpl cannot be cast to org.apache.axis.attachments.Attachments
    at org.apache.axis.AxisFault.makeFault(AxisFault.java:101)
    at org.apache.axis.client.Call.invoke(Call.java:1828)

我认为这是由于两个不同的jar中相同类的冲突造成的.

I think it is due to conflict of same classes in two different jars.

现在，我想知道如何强制jboss从/WEB-INF/lib中存在的axis.jar中加载此特定程序包的类.

Now, I want to know the way by which I can force jboss to load classes of this particular package from axis.jar exist in /WEB-INF/lib.

我该怎么做?

推荐答案

我将分享遇到相同情况时遵循的非常简单直接的过程.

I'll share quite simple and straight forward process which I had followed when I came across same situation.

1>创建一个 jboss-web.xml 文件.

  <class-loading java2classloadingcompliance="false">
  <loader-repository>
      com.rts:archive=DTH_PROD.war
      <loader-repository-config>
          java2ParentDelegation=false
      </loader-repository-config>
  </loader-repository>
  </class-loading>
</jboss-web>

积分:，

• 以带有标记的xml开始，该标记在我发布的代码中不可见 检查上面代码的第三行，
• com.rts -这是您的软件包名称.
• DTH_PROD.war -您要保留的捆绑包名称

• Begin the xml with tag which is not visible in the code I'm posting Check 3rd line of above code,
• com.rts - This is your package name.
• DTH_PROD.war - Name of bundle you wish to keep

2>现在，将此xml文件放入您的项目的WEB-INF目录中，瞧！！

2> Now place this xml file into WEB-INF directory of your project and voilla!!
