I am having a problem with retrieving values from a view that I created. I have created a mapping file, entity and updated my applicationContext to list the entity in the sessionFactory. My DAO attempts to retrieve all values from the view as a list, but it returns a list of the correct size but all null values. What can be causing this, I have another view and other tables that do not give me this issue. Please advise, is there something that I am missing?

I am using Spring3.0.6 and hibernate 3.6.2

I am writing a test client for my ejb and I am getting an exception while trying to do a lookup. I am thinking that my ejb-jar.xml or weblogic-ejb-jar.xml is not configured properly or my value I am passing for the lookup is not correct.

Context ctx = getInitialContext(); DemoHome dhome = (DemoHome) ctx.lookup("demo.Demo"); static public Context getInitialContext() throws Exception { Properties p = new Properties(); p.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.T3InitialContextFactory"); p.put(Context.PROVIDER_URL, url); if (user != null) { System.out.println ("user: " + user); p.put(Context.SECURITY_PRINCIPAL, user); if (password == null) password = ""; p.put(Context.SECURITY_CREDENTIALS, password); } return new InitialContext(p); }

Someone please advise

I am using WSAD and I created a javabean called confirmBean in the default package. It contains two private properties fname, lname and has public setters and getters

In a servlet I placed values in the beans properties, then placed the bean in a request and then forwarded to confirm.jsp

confirmBean cb = new confirmBean();
cb.setFname("testing");
cb.setLname("aaa");
req.setAttribute("mybean", cb);
req.getRequestDispatcher("/confirm.jsp").forward(req,res);

Here is my JSP, I used java syntax for retrieving javabean:

<HTML>
<HEAD>
<TITLE>confirm.jsp</TITLE>
</HEAD>
<%@ page
language="java"
contentType="text/html; charset=ISO-8859-1"%>
<%@ page import="confirmBean"%>
<BODY>

<% confirmBean myBean = (confirmBean)request.getAttribute("MYBEAN"); %>
<%= myBean.getFname() %>

</BODY>
</HTML>

and here is the error i am getting when executing:

Error 500: Unable to compile class for JSP c:\testWorkspace\.metadata\.plugins\com.ibm.etools.server.core\tmp0\cache\local host\server1\Test\TestWeb.war\_confirm.java:3: '.' expected import confirmBean; ^ An error occurred at line: 11 in the jsp file: /confirm.jsp Generated servlet error: c:\testWorkspace\.metadata\.plugins\com.ibm.etools.server.core\tmp0\cache\local host\server1\Test\TestWeb.war\_confirm.java:78: cannot resolve symbol symbol : class confirmBean location: class org.apache.jsp._confirm confirmBean myBean = (confirmBean)request.getAttribute("MYBEAN"); ^ An error occurred at line: 11 in the jsp file: /confirm.jsp Generated servlet error: c:\testWorkspace\.metadata\.plugins\com.ibm.etools.server.core\tmp0\cache\local host\server1\Test\TestWeb.war\_confirm.java:78: cannot resolve symbol symbol : class confirmBean location: class org.apache.jsp._confirm confirmBean myBean = (confirmBean)request.getAttribute("MYBEAN"); ^ 3 errors

Please help!!!

I am trying to implement security constraints to my web app, how do I assign users to the roles in WSAD? Is there an equivalent to tomcat-users.xml?
