从昨天晚上开始我就在尝试这个，我们正在集成两个不同的构建，但仍然无法让所有会话 bean 查找工作。ProjectBeanRemote 位于 project.beans 包中。使用“java:global/JavaFinalProjectS-ejb ...”的查找正在使用一些 bean，但有些没有被查找。使用的持久性单元是 EclipseLink，名称是 JavaFinalProjectS-ejbPU。两种查找方式都引发了命名异常。
public class ControlServlet extends HttpServlet {
/**
* Processes requests for both HTTP
* <code>GET</code> and
* <code>POST</code> methods.
*
* @param request servlet request
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
*/
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
try {
/*
* TODO output your page here. You may use following sample code.
*/
HttpSession sessObj=request.getSession();
if(null==sessObj.getAttribute("proBeaSesObj"))
{
InitialContext initContObj=new InitialContext();
Object initObj=initContObj.lookup("java:global/JavaFinalProjectS-ejb/ProjectBean");
ProjectBeanRemote proBeaObj=(ProjectBeanRemote)
initContObj.lookup(ProjectBeanRemote.class.getName());
sessObj.setAttribute("proBeaSesObj", proBeaObj);
this.sendRequestForward(proBeaObj, request, response, out,sessObj);
}
else
{
ProjectBeanRemote proBeaObj=(ProjectBeanRemote)sessObj.getAttribute("proBeaSesObj");
this.sendRequestForward(proBeaObj, request, response, out,sessObj);
}
}
catch(Exception g)
{
g.printStackTrace();
}
finally {
out.close();
}
}
这是堆栈跟踪

欢迎任何帮助，已经尝试了很多查找方法，但仍然无法全部正常工作。
