[JBoss Seam] - Re: MDA generators with Seam?

by vincent.latombe

About AndroMDA, I never really investigated their seam generator since i've been developping mine. Currently, my generator features pretty much like seam-gen generate-entities, but from a class diagram containing entities and relations : I generate entities + home + queries + facelets. Database gets generated by hibernate-tools from entities. You get an entities-oriented CRUD application and not a Table-oriented like Seam-gen do. And you can specify a lot more on an UML model than on a database schema. I also generate skeleton classes for services, with implementation for queries if needed (extending EntityQuery).

[Performance Tuning] - Re: High Swap Utilization, lot's of RAM free

by PeterJ

RAM is not the same as Java heap. Looking at RAM usage typically does not mean much. Unless you analyze the Java heap usage, it is difficult to say how much memory the app is really using, or how much it really needs. JBoss AS by itself does not need much (64M is probably more than enough), and unless you have a very unusual application I doubt that your application would need 14G of heap. And yes the settings I gave are starting points. You need to analyze the heap usage and adjust those accordingly. I thought occurred to me that the JVM, if given the opportunity (such as offered by your initial heap settings) might grab a significant chunk of memory if it is available. If I have some time, I might wrestle one of our Windows boxes from the performance team and try it out, or maybe one of them knows off-hand.

[JBoss Portal] - Re: Custom layout for a portal page

by bvogt

We have done something similar, i.e. used for whole portals: 1. Define a custom theme 2. Define additional regions in the theme's index.jsp according to your needs. 3. Provide styles in the theme's css files to match your layout (div-renderer?) 4. Assign the custom theme to your page(s) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4077854#4077854 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4077854

[JBoss Seam] - Re: Layering the code in Seam

by fernando_jmt

Yes, magoicochea is absolutely right. By instance, my application is using ACTION + DAO layers. Actions are Seam POJOs and DAOs are Session Beans (EJB). BTW, you can take a look to wiki example in the Seam distribution, it uses action + DAO on POJO components (maybe you want something like that). HTH.

[Installation, Configuration & DEPLOYMENT] - Re: Server Getting Shutdown

by PeterJ

IF you used nohup and the app server is still shutting down after some time, then someone must be shutting it down. There are only two ways I know it can be shut down: 1) The java process gets a SIGINT signal (if this is the problem, good luck finding out who is sending SIGINT, I don't know of any way to track this) 2) Someone called the shutdown() method on the jboss.system:type=Server MBean. You might be able to track down who is making this call, it would take some coding though. Or you could secure the invoker. Regarding Putty, I recall helping someone else who was using Putty and on closing the Putty window the server would shut down.

by asookazian

I didn't see any code and/or UML examples on their website. what exactly does their or your product do? Generate skeleton code (method signatures, etc.) or more?

[JBoss Portal] - Re: How to handle portal specific PageNotFound situation

by bvogt

looking at the sources I would do: 1. extend org.jboss.portal.core.model.portal.DefaultPortalCommandFactory 2. define 1. as mbean in jboss-service.xml of portal-core-sar similar to DefaultPortalCommandFactory but a different name and 3. reference the name of 2. as CommandFactory of mbean org.jboss.portal.core.CoreController 4. re-compile the sources. That seems to work, but is there an opportunity to do this on a declarative basis, i.e. not re-compiling the portals sources? Thanks for any hints in advance (I know there's a lot to do in 2.6...)

[JBoss Seam] - Re: Layering the code in Seam

by monkeyden

Seam does not prevent you in any way from taking that same approach. In fact, it makes some of that much simpler. For instance, using Seam Events or annotated methods you can invoke a business processes from your action without having to explicitly implement the Observer pattern and your action doesn't need to know anything about the process itself. It also integrates nicely with jBPM and jPDL, to simplify the overall implementation of business process. In my estimation, Seam was developed not only to simplify the interaction between the front end and the web tier, but the interaction of all tiers of your application.

mikepaul and apushadow, I'd be happy to update the wiki. Let me try to distill what I've down to the base minimum (and make sure I can repeat it) and I'll update the wiki.

[JBoss Seam] - Layering the code in Seam

by magoicochea

Hello First of all after reading some documentation about seam I have to say that I am impressed by the framework, it seems to solve a lot of problems that I had when trying to develop web applications regardless whether it was .NET or J2EE. However, after seeing the examples I didn't like that the presentation, business and data access code is all mixed up on the same action bean. On the hotel booking example it mentions that for big applications it may be a good idea to layer the code, however, I have not seen this on any example. I am used to do this when working with Spring/Hibernate using Services and DAOs, so at the end I have one layer managing the presentation layer, another for business logic and finally one for data access logic. How would this pattern be implemented on a Seam Application?
