#JSF ICEFACES INTERVIEW QUESTIONS MANUAL#
This can either be automatic or manual as it doesn’t affect the file in any way.Ģ. Debug: In this level, the file gets debugged for possible errors. There are four different types of log levels that are used to show the services that are present inside the logging in JBoss. What are the different types of log levels that are used in logging services in JBoss? If you prefer a more “old fashioned” approach, Seam provides a complete JavaScript remoting framework which lets you call Seam components and subscribe to JMS topics directly from the client.ĩ. First, Seam supports the ICEfaces and Ajax4JSF Ajax component libraries for JSF.
#JSF ICEFACES INTERVIEW QUESTIONS HOW TO#
Please see the Seam booking example application for an example of how to use Facelets.Īnswer: Yes, Seam provides excellent support for AJAX. Facelets provide a powerful templating framework, better application performance, and allows us to write much simpler JSF pages. We recommend you use Facelets, instead of JSP, with JSF. Seam made a major improvement to JSF by eliminating almost all XML configuration for backing beans - you can now define back beans from POJOs or EJB3 components using simple annotations.
We like JSF because it is a component-based UI framework, which fits really well with Seam’s component-based approach to business objects and persistence objects. We plan to support other web frameworks in the future. Is It True That Seam Only Works With Jsf?Īnswer: Seam only supports JSF as a view framework at this time.
#JSF ICEFACES INTERVIEW QUESTIONS CODE#
Where Can I Find Seam Examples And Documentation?Īnswer: The source code and build script of all Seam example applications are included in the examples directory of the Seam distribution.ħ. However, you can use either Hibernate or JPA for persistence, and you can use Seam JavaBean components instead of session beans.Ħ.
To run Seam application in Tomcat, you need a number of additional library files and a few configuration files to bootstrap the JBoss EJB3 inside Tomcat.Īnswer: Yes, as of Seam 1.1, you can use Seam in any J2EE application server, with one caveat: you will not be able to use EJB 3.0 session beans. Also, the JBoss-seam.jar library file from the Seam distribution must be included in each Seam application you deploy.Īnswer: Yes, you can run Seam applications in plain Tomcat 5.5+ or in the Sun GlassFish application server. Make sure that you select the “ejb3” or “ejb3+clustering” profile to include EJB3 support.
#JSF ICEFACES INTERVIEW QUESTIONS INSTALL#
The seam documentation contains instructions for configuring JBoss 4.0.įor Seam 1.2: Since Seam requires the latest edition of EJB3, you need to install JBoss AS from the latest JEMS installer. The seam can still be run against JBoss 4.0. What Version Of Jboss As Do do I need To Run Seam?įor Seam 1.3: Seam was developed against JBoss 4.2. Reduction in the requirements for usage of checked exception.Ī complete new persistence model (based on the JPA standard), that supersedes EJB 2.x entity beansģ. Interceptor facility to invoke user methods at the invocation of business methods or at life cycle events.ĭefault values are used whenever possible. Removal of the requirement for specific interfaces and deployment descriptors (deployment descriptor information can be replaced by annotations). Use of metadata annotations, an extensible, metadata-driven, attribute-oriented framework that is used to generate Java code or XML deployment descriptors. What Are The Differences Between Ejb 3.0 And Ejb 2.0?Īnswer: EJBs are now plain old Java objects (POJO) that expose regular business interfaces (POJI), and there is no requirement for home interfaces. The Java Transaction API consists of three elements: a high-level application transaction demarcation interface, a high-level transaction manager interface intended for an application server, and a standard Java mapping of the X/Open XA protocol intended for a transactional resource manager.Ģ.
#JSF ICEFACES INTERVIEW QUESTIONS UPDATE#
The Javaâ„¢ Transaction API (JTA) allows applications to perform distributed transactions, that is, transactions that access and update data on two or more networked computer resources.
Answer: Java Transaction API (JTA) specifies standard Java interfaces between a transaction manager and the parties involved in a distributed transaction system: the resource manager, the application server, and the transactional applications.
