Re: (EXPERTS ONLY) Bean Creation in Dispatch Servlet

Title: Re: problems installing tomcat on linux

Excuse me, you have this:     System.out.println(zedak.docworx.jspsupport.beans.BrandBean)request.getAttribute("thename"));   before the catch statement, one question: Did you check very well what you wrote in that line ?   Guido. ----- Original Message ----- From: Leon Palermo To: [EMAIL PROTECTED] Sent: Friday, May 25, 2001 9:01 AM Subject: (EXPERTS ONLY) Bean Creation in Dispatch Servlet Hello All,   Let me preface this email by saying that I only put 'EXPERTS ONLY' so you hot shot programmers would actually read this email.  If you are reading this, it worked!   I have an odd problem that I was hoping someone could help with.   I have a servlet that all jsps in the system are dispatched from.  I create a bean in this servlet and add it to the request object like so...       com.blah.blah.MyBean abean = (com.blah.blah.MyBean) Beans.instantiate(this.getClass().getClassLoader(),"com.blah.blah.MyBean");     ...     request.setAttribute("thename", abean);                 I have also tried this to create the bean....       com.blah.blah.MyBean abean = new com.blah.blah.MyBean();   and also tried to place the object in the request like so....       pageContext.setAttribute("thename", abean, PageContext.REQUEST_SCOPE);   Anywho, I then have the following in my jsp page...       <jsp:useBean id="thename" scope="request" class="com.blah.blah.MyBean" />   I get a java.lang.ClassCastException from the jsp.  So, I decided to do a little error hunting in a jsp using the following code...   <%try{     System.out.println(request.getAttribute("thename") == null);     System.out.println(request.getAttribute("thename") instanceof com.blah.blah.MyBean);     System.out.println(request.getAttribute("thename").getClass().getName());     System.out.println(zedak.docworx.jspsupport.beans.BrandBean)request.getAttribute("thename")); }catch (ClassCastException e){     System.out.println("CLASS CAST EXCEPTION!"); } %>   The results of the code is as follows:       false     false     com.blah.blah.MyBean     CLASS CAST EXCEPTION!   So, the attribute is present in the request object, it is not an instance of 'com.blah.blah.MyBean'; but the object's class name is 'com.blah.blah.MyBean'.  Does anyone have an idea what is going on?  How can the object's class name be 'com.blah.blah.MyBean' but not be able to cast to 'com.blah.blah.MyBean'?   Thanks in advance!   Leon Palermo
