[JBoss-user] Porting to and from JBoss experiences...
I am giving a talk at the New England Java Users Group in the near future on portability of EJB 1.1 code. I have had some experience with this with WebLogic and JBoss but I very interested to hear other peoples experiences and thoughts on the subject.

Re: [JBoss-user] JSP compilation error (JBoss+Tomcat)
I had a problem just like this recently. I ended up hacking around it by putting a second copy of common.jar in WEB-INF/lib. As far as the ejb1.jar - create a client version of the jar (home and remote i/f classes only) and put that in WEB-INF/lib.

[JBoss-user] Jikes with embedded tomcat service
Hi, I would like to speed up our jsp compilations so I have been trying to get Tomcat to use Jikes. I have search the usual places and I've tried to uncomment the section in tomcat\conf\web.xml to allow jikes to compile the jsps. This doesn't seem to have made the difference I would have imagined so I suspect that this setting isn't taking effect. My setup is jboss+tomcat 222 on Windows 2k with Oracle on the back end. Has anyone successfully managed to configure jboss+tomcat to work with jikes to compile jsps?

Re: [JBoss-user] JBoss 2.2.1 / Oracle 8i Transaction Problem : URGENT
Doug,
Are you closing your JDBC connections in each method that you use them?
i.e.
public remote1() {
Connection con;
try {
// get Connection
do inserts or whatever;
}
catch ( SQLException e ) {
}
finally {
// also close any open statement objects
if ( con != null )
con.close()
}
}
Ian.

Re: [JBoss-user] Oracle Trigger Problem
I am doing something similar to this except that I am directly getting the
sequence.nextval in the ejbCreate (rather than using a trigger) and setting
my primary key data field in the bean to this value:
ejbCreate ... {
this.id = // get next value from sequence
}
This seems to work great.
Ian.

Re: [JBoss-user] CMP vs BMP
Candide,
If you are using CMP JBoss provides finder methods (for free!) for all of
the bean attributes. Example:
public class MyBean implements EntityBean {
public String name;
public Integer height;
...
}
In your home i/f you can just declare methods:
public collection findByName () throws FinderException, RemoteException;
public collection findByHeight () throws FinderException,
RemoteException;
The naming convention is significant - there is documentation on the web
site regarding this.
This is one of the really nice featues about JBoss.
Ian.

[JBoss-user] ServerException: Load failure - passivation problem?
Hi,I am a 'first time caller - long time listener' and would like to say thatJBoss is a great product - I spent over a year working with WLS and JBossbeats it in may ways - well done everyone everyone who works on it.I am encountering a problem which has been seen before with JBoss 2.0 - i.e.the server working fine then after being left unattended/unused for a whilethrows a ServerException: Load failed. I did a pretty comprehensive searchof the old mailing list archive and Marc Fleury said that this was fixed onNovember 13 2000. I noticed that quite a few files in the JBoss-tomcat.ziparchive (the FINAL-2.0 release) are dated November 14 2000 (although someare earlier). I am wondering if this fix ever got into the final release?Is this fixed in 2.1? I downloaded the jboss-tomcat.zip for the 2.1-beta,but I've noticed that that there aren't all the usual helpful scripts andpre-build conf directories. Before I go racing off installing 2.1-beta Iwould like to know if it is necessary.Incidentally I noticed that when I re-run my servlet which calls the(stateless) session bean (which calls a bunch of entities in a for loop) itcroaks on the 50th iteration of the for loop (which is suspiciously the samenumber as the min cache size for the beans in the standardjboss.xml) - Idon't know exactly the significance of this.TIA,Ian.ps I am using JBoss 2.0 Final on Red Hat 7 with Postgresql as the back end.*** STACK TRACE:[Bean Cache] Passivated overaged bean ConfigurationSet with id = null[Bean Cache] Passivated overaged bean ConfigurationSet with id = null[Bean Cache] Passivated overaged bean ConfigurationSet with id = null[Bean Cache] Resized cache for bean ConfigurationSet: old size = 78, newsize = 50[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ProfileBuilder] ** after creating renderer[ConfigurationSet] TRANSACTION ROLLBACK EXCEPTION:Load failed; nestedexception is:java.lang.NullPointerException; nested exception is:java.rmi.ServerException: Load failed; nested exception is:java.lang.NullPointerException[ConfigurationSet] java.rmi.ServerException: Load failed; nested exceptionis:[ConfigurationSet] java.lang.NullPointerException[ConfigurationSet] java.lang.NullPointerException[ConfigurationSet] at java.lang.reflect.Field.get(Native Method)[ConfigurationSet] atorg.jboss.ejb.plugins.jaws.jdbc.JDBCCommand.getPkFieldValue(JDBCCommand.java:598)[ConfigurationSet] atorg.jboss.ejb.plugins.jaws.jdbc.JDBCCommand.setPrimaryKeyParameters(JDBCCommand.java:344)[ConfigurationSet] atorg.jboss.ejb.plugins.jaws.jdbc.JDBCLoadEntityCommand.setParameters(JDBCLoadEntityCommand.java:92)[ConfigurationSet] atorg.jboss.ejb.plugins.jaws.jdbc.JDBCCommand.jdbcExecute(JDBCCommand.java:157)[ConfigurationSet] atorg.jboss.ejb.plugins.jaws.jdbc.JDBCLoadEntityCommand.execute(JDBCLoadEntityCommand.java:77)[ConfigurationSet] atorg.jboss.ejb.plugins.jaws.JAWSPersistenceManager.lo
