YAR means Yet Another Registration

I feel very sad when i see forums asking for registration to post reply for questions. But this again is unavoidable. The modern age hosting is all about fighting the spam. Or atleast u believe that the sender can leave his/her email id. But in that case what we suggest way be missed out by others registered with the forum.

Recently visited a forum where there was a discussion about integrating jasper(opensource reporting tool) with some sort of product. The person who posted the query looked like a beginner. But there was a reply by a person which was too complex. Then no reply there after. In fact the reply was incorrect and is not the answer for what the question was posted. Hence waste of time and energy.

I believe that people must avoid forums that are not part of the product’s support pages. But posting in the appropriate place, people can reduce these pitfalls in information sharing. Even th

debugging

Debugging has always been an art and will continue to be. Recently i heard the Speech Hackers and painters by Mr.Paul Graham. He has mentioned good points about the art of debugging and it’s importance. It must be taught in academics as well is what i strongly feel. The process of debugging can be compared to some kind of investigation. It’s a brilliant process. Needs thinking.

My favorite one liner about debugging,

“When you have eliminated the impossible, whatever remains, however improbable, must be the truth.”

apache jboss static rendering

Long time back i have thought about this idea. But only few days back i had the oppurtunity to implement. With help of mod-jk, we are albe to comfirtably setup the worker processes. For this apache behaves as the primary webserver to which the request is pointed to. I have seen in many cases where static htmls are still devlivered or handled by the application servers like jboss working behind. It’s just a hit/miss story. So why dont we just have the static html in the apache server and deliver it to the client.

There have been questions on this subject/setup of delivering pages to clients. Since the maintanance is a bit difficult and the software buldling does not entertain this way of setup generally. But i always feel that it’s not fair to allow application servers to server the html’s. One another concern opposing my point could be the authentication or security handles by the applications. But that can be easily avoided by having dynamic rendering and auth in the app and once the auth stuffs are over, it’s just the hits at the webserver. I feel this methodology is more efficient provided we have good engineering of the bundling process.

JBOSS Deployment with Webservice Native Call

Recently i had a problem with a JBOSS deployment. I tried various search engines for the following error.

Search Word: org.jboss.ws.WSException: Cannot obtain UnifiedBeanMetaData for:<Webservice ClassFile>

Look for EJB name correctness in your META-INF/webservices.xml under the element <ejb-link>. The same name is defined in ejb-jar.xml.

Note: This need not be the only solution for the above error. Developer forms are always the one to be used at first hand (if you have time to wait).
This was infact a bad experience for me. When i had to help my friend with deployment problem all that i could do was to search in web(we had very little time and could not wait for the priduct guys to help). After searching all possible web search engines, i was taken to jboss site for the solution. But sadly i had to register to one jboss developer forum which i did and waited for a confirmation mail to activate my account.

Finally another good friend of mine found out where the problem was.

Moral:

I feel that the purpose of developer forum of any product is to give helping hand when ever needed with out asking him/her to fill a long registration form. And asking to wait for the activation mail.

navigating ask.com

Few days back i visited ask search engine’s search page. I was amazed by the interface. In-fact it gives you more than what you want. Quiet entertaining.

I noticed a small issue(it’s big for some people). I hope it might be corrected by the time now. When i entered the city section of the search frame, i was taken to the page. But when i tried to look for images section (to search images) i could not find any link to take me to the images section except my firefox go back button. I felt that i am lost. I feel small things like these should be taken care of before going public.
