[Jboss-dev-forums] [Design of AOP on JBoss (Aspects/JBoss)] - Re: Documentation and usage of jboss-aspect-library.jar

[<bil...@jb...>]

that's because there are none :)

Adrian played with writing some a little, but ditched it.  I'm not a big fan if logging aspects as they are not really logging, they are tracing.

OK,  I must be lost.  I do not find anything on the logging aspects that are under org/jboss/aspects/logging

Any hints?

[Jboss-dev-forums] [Design of AOP on JBoss (Aspects/JBoss)] - Re: Documentation and usage of jboss-aspect-library.jar

[<kab...@jb...>]

Yes,

The aspects are meant for your use. Note that some of these work both inside and outside JBoss (logging, read/write locks etc.), while some leverage Jboss services and thus work only inside JBoss (security, transactions etc.)

You can find some documentation about our aspects here
http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossAOP

If you write any interesting aspects and feel like contributing them back, feel free :-)

yes, we are working on that and make the CMS store content pluggable too.

we will provide hooks at different level to allow 3rd party CMS to be plugged in JBoss Portal.

for 2.2 of course

[Jboss-dev-forums] [Design of AOP on JBoss (Aspects/JBoss)] - Documentation and usage of jboss-aspect-library.jar

[acxsjones <nu...@jb...>]

I am interested to see if 
1.  Is it recommended for users to use some of the aspect's in the jboss-aspect-library.jar.  
2.  Is there any documentation on the funcationality of the aspect's in the jboss-aspect-library.jar

I am wanting to write some logging aspect's and saw some items under logging in this jar.  It would be great if I could use these.

[yxyang <nu...@jb...>]

It will be difficult to use CMSPortlet without careful design of current CMSPortlet. 
For third party developer like me, it is inconvenient to modify the CMSPortlet code and do maintainence. 

I hope JBoss portal team will consider this carefully to provide third party developer a clean solution to use CMSPortlet.

Yang

[Jboss-dev-forums] [Other JBoss Development Design] - Re: Remote debuging with eclipse

[<tho...@jb...>]

Jason wrote,

Ok, I did some research on this, and I have an answer for you. The 
reason why hotcode replace is not working, is because the eclipse 
compiler and the javac compiler are generating different byte code. 
This effectively causes all code changes to be a schema change.

I was able to fix this by changing the my build configuration to use 
the eclipse compiler. These are the steps I took to fix this:

1. Copy org.eclipse.jdt.core_3.1.0.jar from your eclipse/plugins 
directory to your ant/lib. If you are using the build.sh or 
build.bat then this will be in jboss-head/tools/lib.

2. Extract the jdtCompilerAdapter.jar file from 
org.eclipse.jdt.core_3.1.0.jar and put it in your ant/lib (or
jboss-head/tools/lib)

3. Edit your build/local.properties file and set 
build.compiler=org.eclipse.jdt.core.JDTCompilerAdapter

4. do a build clean; build to recompile the main jboss build with 
the eclipse compiler.

I am not sure whether the byte code difference is intentional, it 
could be that this is all a bug, but I am guess that it is not. I 
have not tried the final release of 3.1 (released the 25th). I will 
report back when I find that out.

[Jboss-dev-forums] [Design of JBoss Portal] - Re: Interportlet communication properties

[legolas <nu...@jb...>]

Hi JBossUser,

This is not particularly an issue of JBossPortal, it is a lack in the Java Portlet API specification.
Inter portlet communication has been postponed for the next release of the spec, but at the moment there is not much progress in the next release.

As Yang already mentioned, inter portlet communication can only be achieved using PortletSession using application scope.
portletSession.setAttribute(key, value, PortletSession.APPLICATION_SCOPE);
And retrieve it again using portletSession.getAttribute(key, PortletSession.APPLICATION_SCOPE);
According to the Java Portlet Specificatiopn version 1.0 PLT.15.3: anonymous wrote : Any object stored in the session using the APPLICATION_SCOPE is available to any other portlet that belongs to the same portlet application and that handles a request identified as being part of the same session.

This means that your object is only gauranteed to be available if your portlets are in the same war.

Hope this helps,
Marcel

To use the -javaagent switch, you must use AspectManagerServiceJDK5 as the code for the service.

[Jboss-dev-forums] [Design of Mail Services] - Re: Working on JBMAIL-10

[mikezzz <nu...@jb...>]

Can you find and post the first exception thrown during application start up/deployment?

How are you deploying JBMail to JBoss server?  If you are using the 'dev-deploy' task, try the 'deploy' task.  Make sure that you have deployed to the default configuration.  Also can you check that you have the hibernate3 deployer installed?  Also check that the common-collections jar file has been copied into the deployer directory.

I run on both JDK 1.4.2 and 1.5, so that shouldn't be a problem.

Essentially the jndi name 'jbossmail.HibernateSessionFactory' is not being bound.  Which means the mail.har is not deploying properly.  That would suggest some problem with the hibernate deployer.

Can you confirm that the version of XDoclet in the jboss-mail/xdoclet-lib directory is 1.2.3?

[Jboss-dev-forums] [Deployers on JBoss (Deployers/JBoss)] - deploy comlex application

[Hacki.Wimmer <nu...@jb...>]

Hi,

currently I?m migration several applications from bea to jboss. However, I =
have a couple of EJB=C2=B4s which are used from a couple of web application=
s.

Now I try to find a useful packing and deploy strategy because I have java =
classes which are used from several EJB=C2=B4s and several servlets too. So=
 I have the same class in several deployments (ejb-xyz.jar and web-app-abc.=
war).

I have made many tests with the configuration parameters=20

* Java2ClassLoadingCompliance and=20
* UseJBossWebLoader


so I will have applications which are running!  But I?m not very happy, bec=
ause If I redeploy one application or EJB, I?ll get several ClassCast-Excep=
tions or NoClassDefFound-Exceptions at the runtime of my application. If I =
restart my jboss server these problems not longer occur!=20


Does anyone knows a documentation ? or anything else - how describes deploy=
ment strategies for complex applications?

Many thanks

[Jboss-dev-forums] [Design of AOP on JBoss (Aspects/JBoss)] - building jboss-aop from source

[nichoj <nu...@jb...>]

Hi,

I'm looking to building jboss-aop, to the ends of creating a package of it for Gentoo Linux. So, I downloaded and extracted jboss-aop_1.3.zip, but for the life of me, I can't find an Ant script for building it. Is there something I'm missing? If someone could enlighten me, I would very much appreciate it.

Thanks.

[jeff87 <nu...@jb...>]

I do have the latest. I've tried 4.0.2 and the instructions in the post about running in 4.0.1 (the new ant task and all that stuff). In both instances I get the message


  | --- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---
  | ObjectName: jboss.mail:service=Hibernate
  |   State: NOTYETINSTALLED
  |   Depends On Me:
  |     jboss.mail:name=PagedStore,type=MailServices
  | 

I still have java 1.4.2, should I upgrade to 1.5 as well? What types of things would keep the MBean from installing? 

Thanks,
Jeff

[Jboss-dev-forums] [Design of JBoss Build System] - Re: JBoss Third Party Build

[<rl...@jb...>]

While working on building I ran across an inconsistency with the old system.   In the file modules.ent, from the buildmagic system, the following is defined:

  <!-- AOP -->
  |   <property name="jboss.aop.root" value="${project.root}/thirdparty/jboss-aop"/>
  |   <property name="jboss.aop.lib" value="${jboss.aop.root}/lib"/>
  |   <path id="jboss.aop.classpath">
  |     <pathelement path="${jboss.aop.lib}/jboss-aop.jar"/>
  |   </path>


This file defines only module properties except for the above.  I think this definition should be moved to the libraries.ent file for the following reasons:

1)  Consistency
2)  If the property exists in the libraries.ent file we can give it the proper value (with the version number in the path) when we generate a new one.  If it remains in the modules.ent the property is set and immutable.  The build.xml would have to be modified to reference the correct path.  (bad) 

Are there any reasons why we couldn't or shouldn't do this?

[Jboss-dev-forums] [Design of the JBoss Web Container] - Recompile Custom Tag Pool

[garbett <nu...@jb...>]

I've got a custom tag library, I must be treated as a global resource to all war files.  Everything is fine on a scratch build and install. It's when I edit the tag library, I can't figure out how to get Tomcat to recognize that it's changed. It also has a mysterious way of resurrecting old versions of the custom tag library when I rebuild. I point jasper in the build to the jboss jasper and tomcat libraries, and somehow the build picks the old one back up.

I need to know how to republish a custom tag library so that all the cached and pooled versions get flushed.

[mtedone1 <nu...@jb...>]

Hi, I was going through the org.jboss.deployment.scanner.DeploymentFilter and I saw that it excludes also 'tags'. As for JSP 2.0/Servlet 2.4, 'tags' is a reserved word for a folder under WEB-INF in WAR files, which contains custom files (basically JSP files with .tag extension) which can be included in a JSP page. 

What are your thoughts about it?
