Book Review of “Java Power Tools”

Filed under: Uncategorized — khangharoth @ 7:24 am

I am currently reading Java Power Tools , came across this book on John Ferguson Smart blog.I quite regularly read his blog as he generally writes about current java landscape and good overview of problems faced in current set up say release management,branching strategy ,continuous integration etc.

So on weekend just went out and got a copy of it from nearest Book store ‘Landmark’ in gurgaon.

After going through the index i noticed that we were using mostly all the technologies in various projects barring

a) Continuum,LuntBuild : I am happy with Hudson and no itention of switching to another CI server.

b)Openfire : Haven’t heard of it ,will try to dig deeper into it.

c)JunitPerf ,Jmeter ,Jupiter etc:We are using something else but would like to know more about them especially JunitPerf and Jmeter.

After going through couple of Chapter i noticed that this book is written in very simple and clearly demonstrated the rational behind using these technologies .May be its due to the fact that  i was already familiar with most of the technologies mentioned in the book .

In all i would recommend this book to java developer for a reference book for what’s all tools available for their arsenal.

Few things standout for me :

a) TestNG :

Author pointed this as Next-generation Testing and in my view this is very apt definition for TestNG.Junit has not kept pace with growing demands in testing space and Junit4 is also bit of disappointment.It still lacks on many features and i think way behind TestNg.

One thing i find missing in TestNg chapter is migration strategy and examples for Migrating to TestNG from Junit.But otherwise other aspects of testng were well explained like Test LifeCyclye,managing dependencies in test cases,parallel testing etc.

b) Continuous Integration :

This book cover this topic quite well and give a good overview of various tools available for this like hudson,cruise-control,continuum etc so well covered topic.

c) Profiling and Monitoring using Sun JDK tools:

Its really good to see that this book pointed out some very handy tools available to developer right under their nose ex: Jconsole is really good tool for thick client application monitoring.

I still don’t know why the tools which come bundled with JDK are not so popular inspite of such a  great use.

What this book missed :

a) Aspects :

Aspects is a mainstream concept now and could have been incorporated in this book.AspectJ have now really matured and now comes with good support in IDE like eclipse and Idea.

b) Design analysis tools :

Some insight about determining health of your current project.Some tools which can be discussed are CAP ,JDepend .

c) UML and Reverse Engineering tools :

I think this is also a topic worth considering in this book .Their are some good offerings from IBM which integrated well with Eclipse (although paid).

eUML2 from Soyatech is another good tool for UML and comes with very good eclipse plugin .

In all its a good book for getting a feel of Java landscape. (more…)

Homegrown Persistence Framework

Filed under: Uncategorized — khangharoth @ 3:21 pm

I now moved to new team in my company and task is to set a team in India which  works with london based team on round the clock model.

In process of this migration we inherited existing java code. Functionally this code is in production and is performing quite well.And this project started as small and then grown into a important big project.

Couple of points worth mentioning about this code.

  • Extensive use of Static  : Or Over use of static .Writing Unit tests is big nightmare and now i can fully appreciate how dependency injection is so useful in writing Unit testing.
  • Extensive use of nested classes : Not sure exact need for this kind of architecture.
  • Home Grown Persistence framework.

After working with Hibernate and JDBC ,this is first time i am working a piece of code which can be dubbed as Home grown Persistence framework.Its really nice from personnel prespective after reading all sorts of problem self written Persistence framework could pose.

So am looking forward to get as much prespective on any design approach and  what prompted to be that way.

Also to compare that with hibernate .

Manage your Eclipse Plugin Dependencies

Filed under: Uncategorized — khangharoth @ 3:20 pm

For a Java developer who primarliy uses Eclipse as IDE,managing all the dependecies can be nightmare.It took me quite a while to get euml2 plugin installed and working.

More often downloading a new plugin can leave your eclipse installation in inconsistent state and you are now worse than when you started.

I try new plugins just to get feel of what’s on table from eclipseplugincentral,but am always worried about the dependencies i need to sort between eclipse versions and then plugin’s version.

And then i came across Yoxos ,it just what every eclipse user needs.You select the plugins and it sorts out the dependencies for you.And you get a customised eclipse installtion for you.Really sleak….

It’s really worth giving a try…

Note: Would be a good idea to start building from base Java IDE
