ejb困惑


是这样的,你的EJB打包成JAR单独发布.

解决方案 »

  1.   

    每次都必须打包发布才能看到效果吗？jboss在eclipse中启动，把工程部署到jboss中，可以同步看到效果吗？我这样做一直出错，不知道是哪里搞错了，希望高人指点

    我把错误信息考下来了，请高手帮我分析一下，实在是晕了。HTTP Status 500 - --------------------------------------------------------------------------------type Exception reportmessage description The server encountered an internal error () that prevented it from fulfilling this request.exception org.apache.jasper.JasperException: Exception in JSP: /Test.jsp:129:  InitialContext ctx;

    你的相关的JAR包在放在TOMCAT服务器中,不然会报错的.
