2. Compiled Java bytecode runs at native speed just like the CLI.

I dont think that is the truth. While it would be true that over the years the jvm has been improved upon, the idea of java bytecodes running at native speed is certanly not the truth. It would be possible to attain native speed in certain instances. Certain bytecodes can be optimized bt not all, so the need to inject native codes in areas where performance is not optimal.  Remember there is always still the overhead of compiling bytecodes to native codes

Most Java devs would have heard of hibernate. It’s a nice tool. Haven played and used Hibernate in production I was very impressed with it. Folks like me would have read several blogs of how Arugo enterprises  was able to use Hibernate and terracotta/Caching to scale applications. With the impressive performance seen all over the blogosphere, there is certainly no need to have a rethink about using Hibernate, just jump into the boat of experts.  This might have been what Java experts have been using to cure the impression that Java is slow.

Truth is, while hibernate helps well with ORM, I really doubt if it’s what most of us need. Especially when performance matters. But, u might ask, have u tried Hibernate with the latest ehcache, or sorry JBossCache3.1 appears even more impressive. This should give more compelling reasons to consider Hibernate. From my experience a well designed and optimized DB is orders of magnitude better than Hibernate with whatever combination u choose to bring into the mix. But another would say, but native SQL is possible with Hibernate. Yeah, but it doesn’t still give u the performance of pure jdbc. Some of the Util jdbc support classes in Springframework are good enough to develop a very decent app, with better performance. While Hibernate makes us smell update to date, it might not be what a medium sized app most of us build need. Using JDBC can also help to diverse your skillset to so extent. I mean learning SQL and the workings of your DB. Hibernate shields some of these stuffs from us.

So the buzz about Hibernate terracotta/Caching is all gibberish. Nah! The Scale of most of those apps really warrants and explains the massive performance gain. There are certainly limits to optimization of any DBs engine. But have we even explored the numerous options available? For some, performance within the context of speed might not be all you want in an application. State management, Object Mapping, Object caching, leveraging existing code quality  etc might be good excuses to use hibernate.

Have u been using Hibernate, is the performance overhead noticeable enough to warrant dumping it? Share your  experiences.

Actually replied b4 now, bt for sm reasons my post wasnt visible so i am posting again.

Hey, if u are very serious about this, call 07028093310 or 08028177975. U cld get a demo as long as your intentions are genuine.

It appears the post has been taken out of context. The bulk of what has followed has just been claptraps.

@nolongTing
Thot u were some web design god or holy code ninja haven read your post on experience? For me nothing impressive about your web profile. All i see from you is sheer exhibition of hubris.

@candylips

Nice to know that you are exploring OSGi.  Funny thing is that i have not been devoting enof time to developments in OSGi space. Mite need to get myself updated.

nolongTing:
Your abusive response was really unwarranted

I mean no disrespect. But this same poster, posted not too long ago about a software package (Micro finance banking app). Anyone cares to know those who developed it? The very people he is blasting. It's  a tad absurd to me. While i do agree to some extent that these guyz are not exactly better, we need to rily grow. Some of us churn out rily crappy apps. I dont post here  often, but i perceive the presence of some code ninjas on this forum. To all those striving to make Nigeria  and our IT industry better, may their strength and courage greatly increase.

@javaprince
Hey, I kinda fink dis post was targeted at sbucareer. Nywayz, now his email is available u cld learn more from him. Rily wat logica is askin is on wat basis do u call urself a javaprince wen u make a post like dis (kiddin)? Personally, I perceive u ‘ve got a thirst for knowledge and it is important in ur chosen career path. If u rily like desktop java dev. den I would suggest u checkout dis projects:

Eclipse RCP development using SWT- (for me, nothing compares to dis for java desktop development. Fine I understand Netbeans has support for RCP. Though u mite not be able to achieve d snazzy effects possible with Swing)
Pivot (it’s the new toolkit on the block)
Spring RCP- recently had a release

For advance java technologies I don’t fink u wld get dem in books. U find dem flying around the blogosphere, forums, wiki’s etc.

@candylips
Have u tried Sun’s implementation. Commentaries point to it being very stable, perhaps the best. Not had any serious challenges with it. Not taking anytng away from apache myfaces. And as per availability of components , I must say there are plenty. Try checking out jboss richfaces, Woodstock, commercial icefaces, cant remember some now.

@logica
Who says JSF is built on jsp technology. Wat do u mean by technology here? JSF is certainly a component based presentation framework, based on xml and with built-in support for component lifecycle management. To a large extent JSP and JSF are competing techs. Pliz, note dat JSF displays aint JSP’s coz JSP’s are actually compiled to servlet , for JSF, views are not compiled but rather parsed. No compiler is required.

@candylips
I doubt if a revision of servlet spec is required as most next gen App servers are already providing support, invariably making dem OSGi containers of some sort. check out Glassfish v3.

To modularise web apps, based on OSGi u mite want to check out Spring-DM 1.1 project. It comes with out of box support for Tomcat and Jetty web servers. Also, i fink anoda great project for building module based apps is impala.

I just referenced portlets as providing some form of modularity when it comes to application development. Portlets and OSGi dont actually compete in the same space.

Rily i didnt know they were non-Java JSR-168 compliant Portal Servers.

@Bossman
Tomcat as far as i know is a web server and not often referred to as an App Server as it doesn't support the whole J2ee stack.


@logica
Tomcat being a reference implementation has nothng to do being robust. To the best of my knowledge Tomcat owns about 55% of Java server market, its no surprise SpringSource choose Tomcat for its platform. Tomcat is actually being embed in Jboss default App server

if u glean around the internet for commentaries on WebSphere , i fink it's a very buggy piece of software. Oracle's BEA Weblogic seems to be the most robust of all the App servers(open source / proprietary) around

@Ghenghis
I dont have to pay Sun to get the out of box experience i get with Glassfish.


@candylips
Rily i fink jetty is anoda lovely piece of software with its embed facility,comet support etc

But Caucho's Resin commercial offering seem to be more robust compared to Tomcat

U just developed a great mashup, where wld u rather deploy it to? While I fink plenty of shops in Nigeria are so use to Jboss, I fink Glassfish has been kicking its arse and leading the way in recent times wen u look at rate of adoption and blogoshpere. Even Marc Fleury wld attest to that! Not surprising as Sun has bin throwing resources at it in its bid to gain some market share. Sun seems to be getting some tngs rite these dayz. I must comment that I never rily liked JBoss, my tomcat was just the ideal tng for mi. Perhaps my major gripe with JBoss was its poor documentation. U could throw a stronger machine at it, but, I subscribe to tuning. Fine, I understand open source developers also need to feed their families. I have played around Glassfishv2 and seriously believe it’s better compared to JBoss or Apache Geronimo. It feels performant, startup time is ok and easier to use. The admin interface aint bad at all. Not too many hosting sites have Glassfish offerings, but I fink tngs are beginning to change. Not sure if licensing has been an issue. The Sun rise has a lot to do with this, though it’s not yet reflecting in their books.

I would go with tomcat any day. Just like my tngs simple! Which server do u swear by: Jetty, JonAS, JBoss, Geronimo, Resin, Tomcat or wat?
Share ur thots on which App/Web server is your ideal platform and why.

OSGi seems to be getting all the buzz these dayz. As it not uncommon to see Java server side bloggers spitting OSGi. OSGi is just a module specification by OSGi Alliance. The main theme of the spec is modularization, and component/service orientation. It’s a [b]dynamic [/b]module system for Java. I must say that the “technology” has been around for quite some time, and its bin receiving adoption by the open source community. Ever imagined building modularized apps? I have always believed in apps based on modules but never rily did build apps based on modules cos I didn’t just feel competent enof to do it. OSGi gives me the gut! Nywayz, the lumped up monolithic apps still did the job, so why bother. OSGi is probably going to be the next Big tng on Enterprise Java, as it was made evident in the last JavaOne conference. Almost every meaningful entity on the Java Enterprise bandwagon is going OSGi. Even Sun! The Glassfish community only recently announced their V3 would be OSGi based. IBM, Oracle BEA, JonAs, SpringSource, Jboss etc are not left behind. I must say that SpringSoucre is rily leading the way here in driving OSGi to the Enterprise, with its recent announcement of SpringSource application platform (S2AP). Its not just about war and ear files now, we are looking at par (platform archives). I rily like SpringSource’s offerings, cos not only are their products based on OSGi , it offers developers the opportunity to leverage the OSGi power to build apps. The gud tng about OSGi is that it’s POJO driven. Unlike the confusion called EJB. While EJB3 has seen some measures of improvement, I had gotten off the boat long b4 its release. Spring framework just feels way lighter and simple. I believe the EJB tng added to the Java is hard commentaries. But I must admit dat I have seen shops that have been very successful with EJB. Tell mi am not smart enof, I wld rather say I like my tngs simple. JSR 168 Portlets provide some form of modularity but its nothing compared to OSGi.

Nywayz, back to the OSGi. I recently had an interview, where one of my interviewers was saying their dev team had bin working on an upgrade version of their software for over a year now. I guess they must be building some kinda rocket science software. But, rily, aw much better wld it have been if the app was modularized and as such they cld afford to have incremental releases such that their esteemed customers cld begin to enjoy enhanced features due to the nature of industry they service. I understand dat it’s not all talk wen it comes to delivering great production apps. There are plenty of info online on OSGi. While I not too sure if there are plenty of books on OSGi, articles and tutorials wld definitely get u wet. I am already playing around the major open source implementations ( Eclipse equinox, Apache felix and Knopflerfish). I shld add that OSGi is not all server side, client/mobile side Java also use it. Enof said! If u just have about a year or so left in ur development career den it might not rily be worth looking at.

So are u finking of leveraging OSGi in ur next gig? Java still rules the Enterprise! Share ur thots on this, or similar offerings on Microsoft .NET platform.

Any info on how messages are delivered on these networks would be great.

Tanx!

I just came across this post and thought it might help poeple interested in recruiting programmers. You could take a look at http://blog.slickedit.com/?p=180.
The following points listed in the post are important when recruiting

When hiring, consider what you truly need in your candidates. Don’t fall into the trap of just listing all the technologies you use. Determine which can be learned on the job and which truly require experience.

Examine your interview process. How does each step specifically help you identify the kind of programmers you need? Are you properly balancing intrinsic and extrinsic abilities?

Get your most talented engineers involved with screening candidates. “It takes one to know one.” Great engineers may not be able to describe how to recognize another great engineer, but they know one when they interact with one. The time they spend interviewing candidates will pale in comparison to the time they spend fixing problems created by less capable programmers.

You would be very comfortable with any of this IDEs in about 3 hours. Another added advantage is that you can do your ruby, c/c++, fortan, php, python, also with these IDEs especially with Eclipse. Certainly the best IDEs in the market right now. With solid GUI builders.

Desktop Apps (Swing and SWT-Standard Window Toolkit): Hacks (Tricks and Tips) – Full of swing libraries with their sample source codes. See and do the wows of Java. You would have to think twice before saying never with Java. Also learn how to use Rich Client Platforms –RCPs to develop production ready Apps in less time, cos you don’t have to reinvent the wheel. Great look n feels. You would get great books and tutorials. Your apps shouldn’t look zugly!

Web Development frameworks – Spring 2.0, Jboss Seam, Webwork, Wicket, Struts, Rife, Tapestry, JSF (Java Server Faces), Guice, Appfuse. Hear from the author’s mouth on the pros and cons of this frameworks.

AJAX Libraries (Neat Effects in Web Apps) - GWT, Jboss Rich Faces, Ices faces, GWT-Ext, DWR, Dojo, ExtJs etc.
Design Patterns- Explained and Illustrated with sample codes

Enterprise Apps – Easy access to web/App Servers: Jboss, Glassfish, Tomcat, Jetty, Resin. Greats Books/Tutorials/Codes to help you get started with EJB3

JME(Java Micro Edition) platform – Several JME books and source codes of sample applications to use for prototyping. Mobility development packs for Eclipse/Netbeans.

Plus Other Great Stuffs!

It should be stated here that the only way to be a better a Programmer is not just be reading books but writing codes and reading other peoples codes. You should leverage on this tools to help you fulfill your dreams in the world of Software development. Java Platform is bound to still be around for the next 10 years, cos its open sourced and we are beginning to have more languages (Scala, Ruby, Php, Java FX, JavaScript etc) run on this platform.
