Seam Tomcat Deployment Tutorial Part 4
29 January

Create a Blog with JBoss Seam, Hibernate JPA and JSF then Deploy it to Tomcat in the Cloud – Part IV

  • Posted by Gökhan Ozar
  • Categories Hibernate, Java EE, JBoss Seam, JPA, MySQL, Tutorials
  • Comments 6 comments

In this part of the tutorial we will correct the bugs inherent in version 2.2 of Seam-gen and we will add some code to spice up our blog CMS. First of all, our PostEdit.seam page is not working at all as it is. We shall fix this: Open PostEdit.xhtml from the WebContent folder and find the <rich:tabPanel switchType=”ajax”> block. This is what’s causing the problem, because it has more than one tab – one to …

Best 5 Java open-source web application frameworks

  • Posted by Gökhan Ozar
  • Categories Java EE, JBoss Seam
  • Comments 11 comments

When it comes to developing web applications using Java, writing all the code from scratch has its advantages if you’re trying to master a new technology, but for real life web applications, you have to go for a framework as many expert developers would agree. Otherwise you risk a great deal of failure because of having allocated too much time and too many resources by re-inventing the wheels. There are some hardliners who still argue why …

Matrix of compatible platforms and runtimes with JBoss Tools

  • Posted by Gökhan Ozar
  • Categories Java, Java EE
  • Comments 4 comments

Use Eclipse with the JBoss Tools plugin instead of  JBoss Developer Studio? It can get somewhat tricky to get the right version of the tools plugin to work with the compatible version of Eclipse and the correct version of JSF components, etc. JBoss Dev Studio is a branded version of a Eclipse packed with the right version of JBoss Tools. The dev studio is usually bundled with a developer subscription from RedHat for $99. (I’ve …

Hibernate Derived Properties – @Formula Annotation

  • Posted by Gökhan Ozar
  • Categories Hibernate, Java
  • Comments 10 comments

In Hibernate a derived property (also called a calculated property) is a read-only property whose value is calculated at fetch time using SQL expressions. Example: For an employee entity with properties such as an id and the employee name also a monthlySalary property, you might also want to have a yearlySalary which is not necessarily stored in the database. package net.ozar.exp.entity; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.Id; import javax.persistence.Table; @Entity @Table(name=”EMPLOYEE”) public class Employee implements …

Oracle Database 10g XE Installation and Configuration

  • Posted by Gökhan Ozar
  • Categories Database, Oracle
  • Comments 6 comments

In this article I will write about installing the Oracle Database 10g XE on Windows and changing the default port number for HTTP and optionally for FTP. The installer does not provide any customization option and you end up with the DB server instantly up and running reserving the port 1521 (a default for Oracle database servers), including an embedded HTTP listener set to a default port of 8080 which might conflict with some existing …
