I am looking for WebLogic 10.3 tutorial. and when i searched in net i could not find what is Web Logic
why we have used
Please give me a simple explanation for web logic and tutorial to learn. I already tried to learn from http://docs.oracle.com/cd/E15051_01/wls/docs103/intro/chap1.html#wp1127231 but i am not clear on web logic
The author Frank Munz has an excellent book on WebLogic Oracle WebLogic Server Distinctive Recipes (Architecture, Development and Administration), for specific points.
If you're learning JavaEE , WebLogic is mostly a standard Java EE server, and many of the tutorials from equivalent software systems readily apply to WebLogic development in my experience. Look at widely-used app servers like Jetty or Tomcat, even WebSphere and you'll find there is a large StackOverflow community for supprt. For tutorials see for example DeveloperWorks http://www.ibm.com/developerworks/java/tutorials/j-tomcat/.
For tutorials about specifics of Weblogic, is certainly the right place. ORACLE might assume you're using their 'Workshop for WebLogic 10.3' product http://docs.oracle.com/cd/E13224_01/wlw/docs103/guide/introduction/conWorkshopTutorials.html
.
Could you elaborate a little about what level of tutorial you need?

We currently need a portal solution. One of our service providers has already suggested that we develop the portal in Apache OFBiz.
Now I would like to know if Apache OFBiz is still state of the art or if it is already on the way down.
Or is there another technology we should consider.
Best Regards,
Foerstar
Apache OFBiz is a solid Open Source framework that is actively maintained and updated by its community that is part of the Apache Software Foundation.
While the OFBiz architecture has been outlined years ago, it is still a modern framework that incorporates several pragmatic patterns and is designed to be flexible and extendable. Moreover various components and technologies have been kept up to date or replaced with newer ones over the years.
It is impossible to tell you if OFBiz is a good fit for your portal solution because I don't know your specific needs but my recommendation is to at least consider it especially if in your portal you will publish content related to products or other business entities: if this is the case then the OFBiz universal data model will be a valuable resource that will help you to achieve your goals efficiently and with high quality.
Does anyone successfully replace HornetQ by RabbitMQ in Wildfly 8?
I'm trying to use our enterprise messaging system and extract the logic of messaging from our base app server to separate the concern between messaging and our core product.
I looked on the web and did not find anything useful as how to change the standalone.xml
Any help, even if the answer is - it is not possible - would be great.
Thank you
My bounty is about to expire and I don't see help until now. So, I am answering as per my experience.
From question:
Any help, even if the answer is - it is not possible - would be great.
Don't know, but we don't need to do that. I have found a work around for that.
Answer is RUN RABBITMQ's OWN SERVER
I followed this link to install it on ubuntu server. Then I read these awesome and simple tutorials. Those six tutorials were great base to start with.
I am now integrating the project with my Java EE project which runs on Wildfly 9 server.
Best of luck to anyone who ends up here. Any constructive edits and answers are welcomed.
I am currently looking for a book that will teach me the in's and out's of using the Weblogic 10.3 as my application server.
I am currently using Servlet/JSP/EJB/JSF/JPA as the technology but right now, I am deploying it on Glassfish.
My new project involves the use of Weblogic Server and I dont have any idea how this is done.
Some of the books that I read on the net are a little dated and it covers the Weblogic 8 version.
Not sure though, but I would like to know if somebody has any instructions or preference on how to work around the Weblogic.
I basically wanted to create simple app/build/deploy on this server.
Any hints?
Thanks
I'd suggest you to get your hands dirty and try to build/deploy your app by yourself the first time. There is no mystery in doing it for a simple app. Later on, a good starting point is Oracle WebLogic Server 10g Release 3 (10.3) Documentation Site Map (this is a popular version of WebLogic, you should look for the specific version you intend to use). There is plenty of documentation over there that will help you getting started.
I am looking for a tool capable of generating multiple Xmpp connections to load-test a XMPP server with a secure connection, especially starttls.
For a xmpp plain text authentication I had used jab_simul(followed this tutorial) and tsung both with success.
But I was unable to use the tolls above for the starttls,I peeked into the code of both tools and tried different configurations of the tools.
Another option I am pondering is using a xmpp library like eXmpp and make a specific load-testing tool myself with, instead of altering jab_simul (C software with comments in language i do not understand) or altering tsung(all purpose load-testing tool, so lots of place where you can go wrong).
short-story - I am looking for a tool or advice to stress-testing/load-testing a xmpp server.
We are facing exactly the same challenge right now. After deep consideration we found out that only especially build software can deliver the load we want to test. (Remember, you can configure ejabberd to something very specific :-)
For that we developed a small library called xmpp_talker https://github.com/burinov/xmpp_talker (Apache Licence) which is a kind of xmpp client made as a gen_server. I find it is a very nice starting point to build any kind of load simulation software. There is also echo_worker example included. So, you have good base to start. At the moment xmpp_talker is suited for exmpp 0.9.7. As far as I know in a few days will be out version 1.0.0. (or 0.9.9?) There are many bug fixes (trust me you don't want to know about them). On monday I will release xmpp_talker for exmpp 0.9.8 with proper service interruption handling.
In case you deside to go the same way xmpp_talker could be useful for you.
Added: Here is also great article that is realted to the topic: https://support.process-one.net/doc/display/EXMPP/Scalable+XMPP+bots+with+erlang+and+exmpp
There's also the recently started XMPP benchmarking project called xmppench which aims to be a high-performance benchmarking tool simulating some reasonable use cases of XMPP servers. It's written in C++, based on Swiften and boost.
Do you use Glassfish 2 or v3 in a production environment?
Do you find it robust?
Have you ever been able to find a complete set of documentation?
What do you do when you find that Glassfish ignores J2EE standards, like class and anotation scanning?
Glassfish is Sun's reference standard for a J2EE app server. V3 supports the new 3.1 standard. However, it is only a preview. It is currently scheduled to be released on Dec 10, 2009. Of course, it can always be dangerous to be a very early adopter in a production environment. Currently V3 doesn't support JMS or clustering, for example, but they should be in the final release.
I've used V2 in production for about 3 years and I personally like it. The web admin console makes it very easy to manage (http://localhost:4848, admin, adminadmin), and the performance is good. Here's one example, where someone benchmarked Glassfish: Blog. Of course, you should search for more examples and your YMMV. Here's a Sun document for Glassfish to help Tomcat User.
One last thing that I would add is that Sun ships, and integrates, both Tomcat and Glassfish in their Java IDE Netbeans so you can easily switch between the two app servers to test your particular app.
GlassFish Server V3 or V2 can be used in production environments but the number of users should be less than 1500. Its not very robust and scalable during high load. If used for simple applications GF works perfectly fine, as it is the reference implementation of Java EE standards by Sun which only server to be a guide to other vendors of application servers.
For more complex and high load applications, its better to go to IBM WebSphere Application Server. That's the most robust app server I have seen in my 15 yrs of experience.
Do I use GF in production? no.
Do I find it robust? yes, but I do not tax it very hard.
Have I ever found a complete set of documentation? I think so... the GlassFish v2.1 docs and the GlassFish v3 docs (http://docs.sun.com/app/docs/prod/gf.entsvr.v3?l=en&a=view)
What do I do when GlassFish ignores the J2EE standards? I file an issue here: https://glassfish.dev.java.net/issues/
Do I use in production? Yes. (Now, using 3.0.1)
Is it robust? Yes. But my point of view is from someone that likes to follow the server's developers community and can try some tricks.
What about documentation? The official one is really good, and the developers blogs are a great plus (http://blogs.oracle.com/theaquarium/). What is maybe far from other communities, at the moment, is the collective experience material (like forums), but I think the mail lists are good enough (http://glassfish.java.net/public/mailing-lists.html).
