[JBossCache] - Re: tx completion STATUS_UNKNOWN
by youngm
Guy Pardon of Atomikos justifies his use of "UNKNOWN" saying:
anonymous wrote :
| I think the status cannot be determined for the following reason. Imagine transaction A started in a remote VM and imported in the local VM subsequently. Also, suppose the local VM only does READ_ONLY work.
|
| Then, image two-phase commit:
|
| case 1:
| -transaction A prepares
| -the local VM returns READ_ONLY for all its work
| -transaction A commits
|
| case 2:
| -transaction A prepares
| -the local VM returns READ_ONLY
| -transaction A rolls back
|
| Both cases are indistinguishable by the semantics of the READ_ONLY on prepare: no further outcome is desired.
|
| IMHO, therefore the only state that makes sense is UNKNOWN. It would be a mistake to say COMMITTED, and likewise for ROLLEDBACK.
|

Guy has later said that perhaps he could use "NO TRANSACTION" in such a situation as well, however, it appears the JBossCache 1.4.x code will behave the same for NO_TRANSACTION as it does for "UNKNOWN".
Thoughts? Here is the thread on the Atomikos forum.

[Beginners Corner] - how to package ear and lib, classloader issue
by javatwo
I have an ear application with entity,business and web modules.
<application ...>
foo.par
bar.ejb3
<web-uri>baz.war</web-uri>
<context-root>/</context-root>
The .par, .ejb3 and war files use classes in common.jar. I put the common.jar under /server/default/lib.
In the common.jar,
String className = System.getProperty("FooClassName");
Class.forName(className).newInstance();
trying to instantiate the package.Foo that is defined in web module inside the ear file,
throws a exception:
java.lang.ClassNotFoundException: No ClassLoaders found for: package.Foo
the package.Foo is application specific and can not be put into common.jar that is a common library. However the common lib needs to instantiate the application specific class.
How to solve this issue?
Thanks for any help.
Dave

[Tomcat, HTTPD, Servlets & JSP] - Unable to run facelets numberguess example in JBoss 5
by Annegret
Hi,
We tried to run the numberguess example, which is shipped with the facelets-1.1.13 release on JBoss5.0.0.Beta4.
Just extracted JBoss5 and adding the numberguess.war-file.
The following error occurs during rendering:
"SCHWERWIEGEND: Missing Built-in Tag Libraries! Make sure they are included within the META-INF directory of Facelets' Jar"
