Re: [JBoss-user] JB 3.0.4, loading classes from JAR in EAR
In general you cannot put a jar in an ear and get those classes loaded. The application.xml file is responsible for dictating what gets loaded. If you add a element to application.xml for that jar file it might work but that really should be used for proper applications versus libraries. Putting the jar in deploy is not reliable because you have a chicken-egg problem. Putting it in your [jboss]/server/[config]/lib directory will definitely work as will the base lib directory. If that fails check your [jboss]/server/[config]/tmp directory because it is probably still sitting there. I could swear that if you move from deploy to lib it does not always undeploy but then that's not something you will do very often. That will definitely work but a SAR might be more appropriate than ...[config]/lib. - Original Message - From: "otisg" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, January 22, 2003 2:51 PM Subject: [JBoss-user] JB 3.0.4, loading classes from JAR in EAR > Hello, > > I am trying to use JBoss 3.0.4 and have a > small problem. > My EAR contains a WAR and a JAR.

[JBoss-user] JB 3.0.4, loading classes from JAR in EAR
Hello, I am trying to use JBoss 3.0.4 and have a small problem. My EAR contains a WAR and a JAR. I am deploying this EAR to server/default/deploy. In my application I try to load a class from the JAR by doing Class.forName(). This works fine under JBoss 2.4.4, but doesn't seem to work under JBoss 3.0.4. I suspect that it's something to do with the new Classloader in JBoss3. I have checked the FAQ and this entry looked promising: http://jboss.org/faq.jsp#FAQ-BEANDEV-NORMALJARS However, that didn't seem to solve the problem. I tried sticking the JAR in /lib and server/default/lib/ but nether of those two worked, and the latter actually gave additional errors at boot time (javax.management.InstanceAlreadyExistsException: jboss.j2ee:jndiName=wgen/CommandShell,service=EJB already registered.) The error actually may be a good sign, signaling that JBoss did pick up the JAR, but that I need to repackage thingsmaybe? Any help would be very appreciated.

JBoss doesn't do servlets. JBoss itself, from my experience is the fastest server of its kind on the market. Servlet engines on the other hand are slower than hell, because of the constant compile cycle when you introduce a newly timestamped jsp file. You're probably better off asking speed-related questions for the servlet engine either to the jetty mailing list, or the tomcat mailing list, depending on which servlet engine you're using. Without knowing which servlet engine you're using, it's impossible to tell you any specifics on speeding your jsp pages up. However, one method you can use that is generalized for speeding up a JSP/servlet container, w.r.t. jsp pages, is to precompile all jsp pages before deploying. This can be achieved using jspc for both Tomcat and jetty. Jetty uses Tomcat's jspc. --- This SF.net email is sponsored by: Scholarships for Techies! Can't afford IT training?

Re: [JBoss-user] Can two separate client threads make simultaneous calls?
Complete stack traces are attached. Sorry I didn't give them last time. You may well be right about why these deadlocks not occurring with separate clients. If that's so, is the solution to catch the deadlock exceptions? And any thoughts about the second stack trace (the iterator one)? Thanks, Beau Dan Christopherson wrote: These deadlocks are most likely on your entity beans (the second one is fishy looking, but I really can't say much without seeing more (all) of the stack trace.). By default, JBoss only keeps one instance per bean identity, so each transaction from your client will block on the entity. Give the full stack trace, that might be helpful. launching from different client app instances will change the timings of things, making the deadlock less likely, but perhaps still possible, depending on your application.

[JBoss-user] Message Sending Bean
Hi, Is there a design pattern for a session bean or entity bean which sends messages? Something akin to MDB, but in reverse? Right now I have a session bean which maintains a singleton instance of a connection, and funnels all message sends for my application through a single connection. I could create a pooling mechanism that worked similarly through a session bean, but I was wondering if there was a pattern, or better still, package that other Jbossers were using?

Re: [JBoss-user] Can two separate client threads make simultaneous calls?
There are two messages which appear. The first is: 2003-01-22 11:31:08,725 ERROR [org.jboss.ejb.BeanLock] Application deadlock detected: TransactionImpl:XidImpl [FormatId=257, GlobalId=redbull//3324, BranchQual=] has deadlock conditions.

The other message is this one: 2003-01-22 11:34:34,195 ERROR [STDERR] javax.ejb.TransactionRolledbackLocalException: The iterator of a CMR collection may only be used within the transction in which it was created; CausedByException is: The iterator of a CMR collection may only be used within the transctionin which it was created 2003-01-22 11:34:34,196 ERROR [STDERR] at org.jboss.ejb.plugins.AbstractTxInterceptor.invokeNext(AbstractTxInterceptor.java:224) 2003-01-22 11:34:34,197 ERROR [STDERR] at org.jboss.ejb.plugins.TxInterceptorCMT.runWithTransactions(TxInterceptorCMT.java:178) 2003-01-22 11:34:34,198 ERROR [STDERR] at org.jboss.ejb.plugins.TxInterceptorCMT.invoke(TxInterceptorCMT.java:60) I certainly understand the nature of the transcation/iterator restriction, but why would these calls from separate client threads be tickling this?

[JBoss-user] JBoss Project Structure Convert
I have been using JBoss Appserver for well over a year now. I use Sun One Studio for development and deploy in Jboss using Ant. I have been working all this while with virtually no documentation (dont blame me! read on). I recently stumbled on the "Jboss 3.0 Quick Start Guide - Andreas Schaffer", The pdf was VERY scanty (apologies) but the template project of chapter 3 gave me a good insight on how JBoss projects are structured. I have fallen in love with the structure and I have gone ahead to check out jboss head. but I cannot find the mentioned template project!, where can I find it and how can I convert my project structure to the jboss standard? I can hardly wait to start using XDoclet (perhaps a guide on xdoclet will also help). thanks in advance. ps: please no body should suggest that I subscribe for the official docs. we in Nigeria do not have access to credit cards so I cant purchase it online. I have asked a friend who is based in US to help me purchase it, but that will take time. -Michael UkpongEnterprise Portal ArchitectSocketWorks Ltd+2348033473455-With Yahoo!

Re: [JBoss-user] Session Id not reinitialized
3.0.6 will be out soon (early next week?) Please repeat the test in that and if the problm persists, mail again with more detail - i.e. a blow-by-blow account of exactly what you did from both boxes and what behaviour you observed.

[JBoss-user] How to store the persistent messages?
Hi, I am using Jboss 3.0.0 and in my application i want to get(track)all the persistent messages in my JMS module, In Jboss all the persistent messages are stored on hard disk or database, i want to store all these messages into my own database for further processing, Jboss by default it is using HSQL database and i am able to see all the messages but i am not able to store all the massages into my own databse(like mysql), i tried to change the database to mysql but it's not reflecting, how to store all these messages into my own database? Any idea? thanks , madhu sudhan --- This SF.net email is sponsored by: Scholarships for Techies! Can't afford IT training? All 2003 ictp students receive scholarships.

[JBoss-user] JBossMQ / MDB extensions
How is it possible to include major source upgrades ( some new classes, some modifcations of existing classes ) into the regular JBoss/JBossMQ source WITHOUTdeveloper CVS access ? We have developped some missing - but for JBoss usage in a more complex JMS production environment vital - JBossMQ / JBoss MDBContainer extension features ( e.g. global destination message counter / queue depth state informations, performance counter and redelivery delay for MDB's invocations ). We would like to include these features into the regular JBoss distribution for avoiding maintenance of a proprietary JBoss version ( maybe some other JBoss JMS user also need these features ?!? ) Regards Ulf
Re: [JBoss-user] LDAP configuration
the most comfortable way will be the jndi path. the jndi namespace in jboss is a federated one, so you are able to integrate external namespaces like dns, ldap, filesystems, c++ or your anchestry tree seamlessly into the jndi tree. you may then manipulate the objects via normal jndi lookup and search routines, respective the appropriate object factories. it is explicitely described in chapter 3 "Naming on JBoss - The JNDI Naming Service" of the jboss book, in the ExternalContext MBean config: ldap example with parameters in jboss.ldap : external/ldap/jboss jboss.ldap javax.naming.ldap.InitialLdapContext true here we will bind the filesystem according to local.props : external/fs/usr/local local.props javax.naming.InitialContext jboss.ldap: java.naming.factory.initial= com.sun.jndi.ldap.LdapCtxFactory java.naming.provider.url= ldap://ldaphost.jboss.org:389/o=jboss.org java.naming.security.principal=cn=Directory Manager java.naming.security.authentication=simple java.naming.security.credentials=secret local.props: java.naming.factory.initial= com.sun.jndi.fscontext.RefFSContextFactory java.naming.provider.url=file:///usr/local for your anchestry tree please use the settings accordingly ;-) bax > Von: madhu sudhan <[EMAIL PROTECTED]> > Organisation: infoglyptic > Antworten an: [EMAIL PROTECTED] > Datum: Wed, 22 Jan 2003 16:15:57 +0530 > An: [EMAIL PROTECTED] > Betreff: [JBoss-user] LDAP configuration > > Any one having any idea about how to connfigure External LDAP server in > jboss3.0.0 . > thanks in advance > > > --- > This SF.net email is sponsored by: Scholarships for Techies! > Can't afford IT training?
