How to switch Workspace in WebSphere Studio Application Developer(WSAD)

Actually with WSAD v5.1.2 version we don’t find ‘SwitchWorkspace’ option like MyEclipse and with this feature that come with RAD 6.0.

However, we can change the workspace by changing the workspace directory which WSAD prompts on starting the workbench.

If, we checked the 'Use this workspace as default' option, then we will have to go to the command prompt and type in the following:

'C:\WSAD\v512\wsappdev -setworkspace'. (Usually WSAD is stored here).

If it is in a different location on your PC, then type in \wsappdev –setworkspace

What is the difference between Iterator and Listiterator ?

There are two Differences are there :

1. We can use Iterator to traverse Set and List and also Map type of Objects. But List Iterator can be used to traverse for List type Objects, but not for Set type of Objects.

That is, we can get a Iterrator object by using Set and List, see here :

 By using Iterator we can retrieve the elements from Collection Object in forward direction only.

Methods in Iterator :

1. hashNext()
2. next()
3. remove()

Iterator ite = Set.iterator();
Iterator ite = List.iterator();

How to create a Repository in CVS

CREATE a REPOSITORY

First off, you need to create a repository directory on some stable, trustworthy host. This directory is probably called something like

• /opt/CVS
• /usr/local/CVS
• /mnt/CVS

You get the idea. Create this directory.
You need to set the envar CVSROOT to the name of that directory. For now, let's not worry about multiple repositories; we'll just note that by changing the envar you can make CVS look in one or another of several repositories, should you happen to have several.
There's a script cvsinit that came with CVS. You should use this script to help initialize your new repository. As the CVS INSTALL guide says, "There are many ways to customize CVS for your site. Read the cvs(5) manual page when you get the chance." I couldn't put it better myself.

Now we'll assume that you survived all of the above, and that you have a properly configured repository.

HibernateSearch in Action ebook Download

Enterprise and web applications require full-featured, "Google-quality" search capabilities, but such features are notoriously difficult to implement and maintain. Hibernate Search builds on the Lucene feature set and offers an easyto- implement interface that integrates seamlessly with Hibernate-the leading data persistence solution for Java applications.

Hibernate Search in Action introduces both the principles of enterprise search and the implementation details a Java developer will need to use Hibernate Search effectively. This book blends the insights of the Hibernate Search lead developer with the practical techniques required to index and manipulate data, assemble and execute search queries, and create smart filters for better search results. Along the way, the reader masters performance-boosting concepts like using Hibernate Search in a clustered environment and integrating with the features already in your applications.

Hibernate in Action ebook Download

Hibernate practically exploded on the Java scene. Why is this open-source tool so popular? Because it automates a tedious task: persisting your Java objects to a relational database. The inevitable mismatch between your object-oriented code and the relational database requires you to write code that maps one to the other. This code is often complex, tedious and costly to develop. Hibernate does the mapping for you.

Not only that, Hibernate makes it easy. Positioned as a layer between your application and your database, Hibernate takes care of loading and saving of objects. Hibernate applications are cheaper, more portable, and more resilient to change. And they perform better than anything you are likely to develop yourself.
