[JBoss-user] [Beginners Corner] - ScheduleManager Bug
This may not be a good posting for Beginners Corner, but I sure wasn't able
to find another forum that seemed like a good fit. Here goes.
We are using the org.jboss.varia.scheduler.ScheduleManager class, and have been
getting ClassCastExceptions. Looking at the code, I can see why. There are a
number of places where there is code like this:
| Iterator i = mSchedules.entrySet().iterator();
| while (i.hasNext()) {
| ScheduleInstance lInstance = (ScheduleInstance) i.next();
| ...
|
Unless the mSchedules map is empty, this code is going to throw a
ClassCastException every time, because the entrySet method on a Map produces a
set of Map.Entry objects. The code should say something line the following
instead:
| Iterator i = mSchedules.values().iterator();
| while (i.hasNext()) {
| ScheduleInstance lInstance = (ScheduleInstance) i.next();
| ...
|
If you need the key and the value, you would do something like:
| Iterator i = mSchedules.entrySet().iterator();
| while (i.hasNext()) {
| Map.Entry entry = (Map.Entry) i.next();
| Integer id = (Integer) entry.getKey();
| ScheduleInstance lInstance = (ScheduleInstance) entry.getValue();
| ...
|
I would be happy to submit a bug report, if someone could (politely) point me
to the right place to do so.

[JBoss-user] [Beginners Corner] - Re: Does JBoss support Java server faces ?
The simple answer to your question is yes, you can use JSF with JBoss. In fact we are about to release a product that does just that. We've been using JSF for several months now, so my memory of what we had to do to get it to work is a little foggy. I do recall that we had a few problems with locating the TLD files, that we ended up working around by extracting the TLD files from all of the library jars we were using (including jsf-impl.jar) and copying them into the WEB-INF directory of our war files. The work-around was needed because of a class loader issue that the JBoss team was aware of, so it may have been fixed by now.

[JBoss-user] [JCA/JBoss] - Who Starts PostgreSQL?
We are currently converting from hypersonic to PostgreSQL and I have a simple question. The answer may already be in the forums, but search doesn't seem to be working today (searching all forums for postgres or postgresql produces zero results!). My question is this: When using Hypersonic, JBoss starts up the Hypersonic database during the JBoss startup sequence, and shuts it down when JBoss shuts down. Can we configure JBoss to do the same with PostgreSQL? Does anyone have any experience doing this? The instructions we have found on the forum so far describe how to configure the adaptor that connects to PostgreSQL, but not how to configure JBoss to start/stop PostgreSQL. Any help would be appreciated.

[JBoss-user] [JCA/JBoss] - Re: Who Starts PostgreSQL?
Thanks for the quick answer! It will save me a lot of looking for something that isn't there! We are building a system where JBoss is the primary software framework, and we are developing MBean services that run monitor the status of the system, and may restart all or part of the system if problems are detected. In this context, the primary advantage I can see to having JBoss start Postgres is that we can know whether Postgres started up properly or not (e.g. look at any System.err output), and can restart it from within JBoss (along with any dependent services) if necessary.

[JBoss-user] [HTTPD, Servlets JSP] - Upgrading a JavaServer Faces App from JSF-1_0 beta to the Of
Sun has recently released the official 1.0 reference implementation for JavaServer Faces (replacing the beta version released in December of last year), and I have managed, after some pain, to upgrade a simple application that I had developed and was running with JBoss 3.2.3 and Tomcat 5. I thought I would share my experience, so the next person won't take as long to figure things out as I did. First, there are a few syntax changes, such as tags changed to use camel case (e.g. output_text becomes outputText). There is a Major changes/features in this release section in the newly-released JSF 1.0 specification that describes these changes, and the error messages you get are reasonably straightforward, so this likely won't cause too much trouble. The most time-consuming problem I encountered was due to the fact that the class com.sun.faces.config.ConfigListener was renamed to com.sun.faces.config.ConfigureListener in the official release, and even though I didn't reference that class anywhere, I kept getting a classloader error indicating that com.sun.faces.config.ConfigListener could not be found. I wondered if something was being cached, but even shutting down and restarting my server didn't help. What I finally discovered is that the old class name was being referenced in a file in the work directory, related to my application (called jsf-test): | /usr/jboss/server/default/work/jboss-web/localhost/jsf-test/tldCache.ser | This was probably overkill, but I simply deleted the entire work directory, restarted my server, and no more classloader problem. a href=http://www.jboss.org/index.html?module=bbop=viewtopicp=3824418#3824418;View the original post/a a href=http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3824418Reply to the post/a --- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.

[JBoss-user] [HTTPD, Servlets JSP] - Re: Standard taglib with jboss 3.2.3, tomcat 5
I ran into the same problem trying to deploy the JavaServer Faces 1.0 Beta samples on JBoss 3.2.3, with Tomcat 5. The suggested work-around (i.e. false) appears to solve the problem of locating the taglibs, but I found that it led to other classloader-related problems. For example, the first thing I ran into was that debug classes contained within jars in the sample war's WEB-INF/lib directory didn't match identical classes that had previously been loaded by the JBoss class loader. In order to deal with this problem, I experimented some more and found that if I copied all of the TLD files that were in any of the jars in the WEB-INF/lib directory into the WEB-INF directory, then I found that the system was able to find the TLD files, and I no longer needed to set the UseJBossWebLoader property to false. To make my life easier, I developed a small ant file to do the necessary conversion: Note that you need to specify the war-name (the name of the war file you want to convert) and the deploy-dir (the name of the directory to which you would like to deploy the war file). If you just want to modify the war file, you can just invoke the copyTlds target, and you don't need to specify a value for the deploy-dir in that case. Also note that I tried this with one of the the JSTL samples (standard-examples.war), and it appeared to work for that as well. So now we have two work-arounds to choose from: 1) set the UseJBossWebLoader property to false 2) copy the tlds into the WEB-INF directory The bottom line here is that the JBossWebLoader doesn't seem to be looking for TLD files within the jars in the WEB-INF/lib directory. Are there any plans to fix this?
