Hey all, I've been developing a few JSF applications lately and am disturbed with the inconsistency in the web component APIs. I've noticed that there is extremely unpredictable behavior when calling .getValue() or .getSubmittedValue() on a JSF component object in server side code. Sometimes when I call .getValue() on a drop down list...

We use Tomcat to host our WAR based applications. We are servlet container compliant J2EE applications with the exception of org.apache.catalina.authenticator.SingleSignOn. We are being asked to move to a commercial J2EE application server. The first downside to changing that I see is the cost. No matter what the charges for the app...

Part of your answer should include your arguments for your decision. And also how much experience you have with the Java EE server you choose and with the other available servers on the market. These are...
Hi, I've been using the Java Pet Store and .Net Pet Store examples for years when comparing JEE and .Net performance in an eBusiness type setting. Is there a better way to compare the performance of JEE and .Net for this type of application? Update: As some have pointed out below, the implementation, framework versions, architecture...
I'm trying to bind one of my model objects to the fields of a form, using Spring-MVC. Everything works fine, except that one of the attributes of the model object is an unordered collection. Doing something like <c:forEach items="${m.items}" var="i" varStatus="itemsRow"> <form:input path="items[${itemsRow.index}]"/> </c:fo...
Let's share Java based web application architectures! There are lots of different architectures for web applications which are to be implemented using Java. The answers to this question may serve as a library of various web application designs with their pros and cons. While I realize that the answers will be subjective, let's try to be...
I've got a somewhat dated Java EE application running on Sun Application Server 8.1 (aka SJSAS, precursor to Glassfish). With 500+ simultaneous users the application becomes unacceptably slow and I'm trying to assist in identifying where most of the execution time is spent and what can be done to speed it up. So far, we've been experim...

Hello, I'm teaching Java EE at the university, and this was a question a student asked. I said "no", but I wasn't really sure, so I thought I might ask you mighty developers. :) Basically, what I'd like to do is to use entities if they were in my context: cat getters, setters, etc, so like normal POJOs. if I use an EJB using its remote...
Hi All, I have an application that allows different users to update some data that is then published to a website. The application uses JPA as a persistence layer. I now want to add a bit of workflow management to this scenario so that when users with junior roles update data, it is not directly published but rather waits for a senior u...

I've read the EJB3 spec and the latest O'Reilly and Manning books and yet I can't see defined anywhere how transactions are propagated over multiple session beans. For example, if I call a method marked as "NEVER" on bean A and bean A calls a method marked as REQUIRESNEW on bean B, what happens? In practice, using JBoss, we've observed...
I need to put an LDAP contextSource into my JEE container's JNDI tree so it can be used by applications inside the container. I'm using Spring-LDAP to perform queries against ORACLE OVD. For development, I simply set up the contextSource in the Spring xml configuration file. For production, however, I need to be able to use a JNDI looku...
I have a web app with a web-based configuration UI. If the user accesses via HTTP, I want to alert the user that they should really use HTTPS and give them a link to click on to get to the HTTPS-prefixed URL. Now, this is pretty straightforward if we're on the default ports, but often, we're not - for example, HTTP might be on 8080, wit...
