Hi, I have a problem with displaying data on jsp page. It is similar to the
TrailBlazers and did work before by the way. Wish anyone give me some helps,
thanks.
The method in javabean is:
public Collection getUser(){
String oql = "select u from UserCredentialsEntity u";
return em.createQuery(oql).getResultList();
}
The code in jsp page is:
<%
Collection people = aUser.getUser();
for(Iterator iter = people.iterator(); iter.hasNext();){
UserCredentialsEntity user = (UserCredentialsEntity)iter.next();
%>
Username: <%=user.getUsername() %>
<%
}
%>
The error message is:
org.apache.jasper.JasperException: Exception in JSP: /test.jsp:29
26: <%
27: Collection people = aUser.getUser();
28: for(Iterator iter = people.iterator(); iter.hasNext();){
29: UserCredentialsEntity user = (UserCredentialsEntity)iter.next();
30: %>
31: Username: <%=user.getUsername() %>
32: <%
