Hcl Jboss Seam Interview Questions

1) What version of JBoss AS do I need to run Seam?
For Seam 1.3: Seam was developed against JBoss 4.2. Seam can still be run against JBoss 4.0. The seam documentation contains instructions for configuring JBoss 4.0.

• For Seam 1.2: Since Seam requires the latest edition of EJB3, you need to install JBoss AS from the latest JEMS installer. Make sure that you select the "ejb3" or "ejb3+clustering" profile to include EJB3 support. Also, the jboss-seam.jar library file from the Seam distribution must be included in each Seam application you deploy. Refer to examples in Seam distribution (inside the examples directory) to
see how to build and package Seam applications.

JBoss Interview Questions and Answers

3 comments Posted by Stephen thangaraj at 16:09
How do you monitor JBoss and detect the bottleneck of an application?
Answer :: The first step is to measure the different components of your app to see where the degradation is. Isit an external resource (database, message server, etc.)? Is it internal? Where is the app spending all its time?

So the first step could be to to use JBoss JMX agents and monitor the components deployed to the application server. Once it's clear which component or library takes most of the time or most of resource you can use a more specialized tool like JProbe and examine the single method or the single objects loaded in memory. ....


Whatis JBoss JBPM ?
Answer :: JBoss jBPM is a platform for process languages. At the base there is a java library to define and execute graphs. The actual process constructs like e.g. send email, user task and update database are defined on top of this. Every process language is made up of a set of such process constructs. And that is what ispluggable in this base library. On top of the JBoss jBPM base library, there are implemented several process languages as a set of process constructs: jPDL, BPEL and SEAM pageflow:
jPDL is a process language with a clean interface to Java and very sophisticated task management capabilities. There is no standard for Java process languages, so it is proprietary. BPEL is a service orchestration language. As said before, in BPEL, you can write new services as a functionof other services. This is typically a component of an Enterprise Service Bus (ESB).SEAM pageflow is a language that allows for the graphically define the navigation between pages in a SEAM web application.
