problem in using ui:fragment

Sat, 5 Jul 2008 15:02:26 MDT

I am using Seam with hibernate and has a problem writing ui:fragment.
I have following code in my .xhtml

code:

<ui:fragment rendered="#{rcvrInfo.deliveryTypes.contains( new DeliveryType("Postal") }">

ReceiverInfo class has following attributes

code:

private Set<DeliveryType> deliveryTypes = new HashSet<DeliveryType>(0);

There are two problems:

1. How to read double quotes inside double quotes.
2. I tried same code in Java Class but it says result is "false" while the expected result will be true.

code:

rcvrInfo.deliveryTypes.contains( new DeliveryTyp...

seam contrary to MVC ?

Fri, 4 Jul 2008 11:54:22 MDT

Hello ,
Am trying to explore SEAM and after looking at the first example my views are ::

Using EL we bind the data to a backed up bean
( advantage being no need to manually set values )

Backed up bean needs to have wo annotations
@Name & @Scope

Action Listener is bound to the UI using a annotation of @In

After looking at all of this * am used to developing apps using struts )

I find struts much cleaner and much more layered

Seam in an attempt to avoid XML seems to have annotations freely thrown around

My understanding is SEEMS totally violates MVC - here the View is configured with Model

I am new and maybe I do not understand...

JBoss health monitoring

Fri, 4 Jul 2008 09:12:22 MDT

What are some best practices on ways to monitor the overall health of the container (e.g. pools, JNDI, EJBs, etc.)?

server.xml ?

Fri, 4 Jul 2008 07:14:21 MDT

hi rancher,
we can define the datasources in server.xml ?

checking health of connection pool

Fri, 4 Jul 2008 05:02:21 MDT

Hello ,
Have set up a Datasource in Jboss .

Wanted to know if there is any way to check the health of the connection pool ?

Option a >
Any admin interface which specifies no of connections in use / no free

( Have faced issues in other projects ( using ATG server ) where poor code was causing connection leaks - but there was no GUI to show the status / health

Option b >
Is there any way programmatically that I can set a threshhold limit and raise an alarm email once that min limit is reached ?

Thanks ,

Jboss in Action: Running JBoss as windows service

Thu, 3 Jul 2008 11:31:08 MDT

Hello Javid and Peter

We have been using java service wrapper for running JBoss AS as windows service in production environment.

However there is another way using JBoss Native (http://wiki.jboss.org/wiki/JBossNativeWindows).

I would like to ask, which approach would you recommend for production environment, advantages, disadvantages, best practices.

Thank you.

asking the best next question to have as many rules fire as possible

Thu, 3 Jul 2008 05:29:07 MDT

Hi,

We are building with a team an application for matching "green customers" to "green companies" based on rules that match customer (wanting to save energy, money and climate) to green companies that offer "products to save energy, money and climate"

We are evaluation if drools would be a good tool for this.

Now my question: (how) will drools (or any other rule engine) be able to support the process of "asking the best next question to have as many rules fire as possible"? but without having to code in each rule some relationship with other rules in the rule base explicitely, because that would make the rule base very hard to maintain when we have hundreds or maybe even thousands of rules in the future....

From Microkernel to 'All'

Wed, 2 Jul 2008 16:05:06 MDT

One of the things I like about the JBoss configuration approach is the use of JMX Beans to build a server to match your needs. Having said that I haven't delved too deeply into that realm. Part of the reason is that I find getting to this level fraught with frustration. Does your book bring out solid examples in this area? Also with lightweight containers such as Spring about.. how would the microkernel compare? Finally.. just how lightweight can this be (of course you have hardly any services at that level)? Do you have any extreme examples of deployments say on limited or embedded hardware?

Cheers,
Jon

Connection pooling

Wed, 2 Jul 2008 00:43:04 MDT

Hi,

I'm using jboss app server and oracle db server. I had written a oracle-ds.xml file and delployed in jboss to get the connection pool feature,its working fine.
But is it possible to define the connection pool properties using jboss web console for each web application?

For every database we need to write -ds.xml file. Is there any other alternative.

and I need to use clustering feature of jboss how to do it?

JBoss in Action: different class loaders for each web application

Wed, 2 Jul 2008 00:27:04 MDT

Hi,

I have a question to Javid and Peter.

We are trying to deploy two, different, applications (let's say APP1 and APP2) recently but we have a problem as one of them use reverse ordered class loader. What we find - after deployment - is that classes are mixed up within applications. We have shared components (shared libs) which provide access to APP1 (reverse ordered class loader) from APP2 (standard class loader). But when we try to access APP1 from APP2 through the API from the shared libs, Java gets confused.

We would like to assure, somehow, that APP1 is encapsulated and has no access to shared libraries at all. Additionally we would like to make APP1 be available for APP2 - as we need it's features...

Websphere to JBOSS migration

Tue, 1 Jul 2008 21:59:03 MDT

I have an application that runs on Websphere 6.0. I manually created the jboss-web.xml and jboss.xml (for ejbs) to deploy the new EAR on JBOSS.
Now if we migrate to higher versions of Websphere for higher J2EE version compliance, are there any tools that can migrate the EAR to equivalent JBOSS versions?
Thanks

JBoss in Action - Clustering and performance

Tue, 1 Jul 2008 12:11:02 MDT

Javid and Peter,

It's been rather common nowadays the requirements to cover some kind of redundancy, failover or cluster. Does the book cover these topics. Does it include some "odd" setups like multiple clusters on the same network, or multihomed servers?
And about performance, is this topic covered? Trimming is a good point, but what about tuning some key parameters that offer some gain over the "just-unzip-vanilla-install"?

Thanks,

Migration from BEA Weblogic to JBoss

Tue, 1 Jul 2008 11:13:02 MDT

Hi,
We need to migrate from BEA Weblogic 9.1 to JBoss.
What are the roadblocks that we can expect in this process.
We currently use weblogic's T3 protocol for all the lookups.
What will be the equivalent substitute for JBoss.

Please forgive me if this is a very naive question. I have just started learning about these application servers and have a long way to go..

Thanks a lot.

Dear Javid and Peter, I thank you for your book, it could not have been more opportunate and timely for me who is just learing the migration path from JBoss 4.X to 5.0.

Hi,
I am working in JBOSS for developing new service. I would like to access the JBOSS POJO cache and get the data just in case there is any upgrade activity or system fail over.
It will be helpful if you could tell as of how data can be restored by accessing the JBOSS POJO cache.
I am new to JBOSS so it would be better if you could give me link to know more about JBOSS cache & its features.

Thanks in advance,

Pre-Configured servers

Is there much value in using the minimal server?
Is the only gain the startup time?
Are there different consideration for development and production?

Book Content - JBoss Microcontainer

Tue, 1 Jul 2008 08:15:01 MDT

I checked out the TOC for JBoss in Action and one of the items that gave me pause (made me go 'Hmmm') was mention of the "JBoss Microcontainer". As I really hadn't heard about this previously (I primarily work with WAS, Tomcat, and BEA), I did a quick google search and came up with this very brief write-up:

http://www.jboss.com/products/jbossmc (http://www.jboss.com/products/jbossmc)

I gather that this provides an IOC mechanism, but the JBoss page seems to indicate it is more unique than this.

What makes this "Microcontainer" unique, and what are some concrete examples for what I might use it? Does the book get into these issues?

Tue, 1 Jul 2008 08:11:01 MDT

I have developed Hibernate and Spring based application on JBoss server. Now we are planning to use JMX based deployment of Spring and Hibernate.

I would like to know how easy to do it ? How "JBoss in Action" uncovers these features ?

Going forward, we are planning to use Aspect J and AOP extensively on JBoss for core business logic. How "JBoss in Action" covers these features for developers like me ?

Last not but least, is these any chapter dedicated on migartion TO JBOSS from industry standard servers ? Whole bunch of application waiting for migration and we do not have any clue for extimation. We had real hard time when we migrated SUN IDM on JBoss because of bad documentation from Sun.
