JBoss appearing to hang???

[hemalshah]

Hi I am running JBoss along with Tomcat. I am trying to deploy EJB's. I am using a mysql database.

When I attempt to run JBoss it seems to hang for a few minutes. The last lines are as follows:

[Mail Service] Mail Service 'Mail' bound to java:/Mail
[Mail Service] Started
[MySql] Starting
[MySql] XA Connection pool MySql bound to java:/MySql

After a few minutes I get the following trace:

Does anyone know why I am having this problem?

Thanks in advance.

[roadrunner]

As I've said before please provide the section of your jboss config where you setup mysql and the version of jboss you have.
Can you connect to mySql with "normal" jdbc ?
Is there a firewall that my block the request ?

regards
Sven

btw: I also had touble getting the jdbc stuff working because jboss sometimes has a "strange" view how the configfile should look like

[hemalshah]

This is what I have in my JBoss.jcml file:


org.gjt.mm.mysql.Driver,org.hsql.jdbcDriver,org.enhydra.instantdb.jdbc.idbDriver



org.opentools.minerva.jdbc.xa.wrapper.XADataSourceImpl
mySQL
jdbc:mysql://localhost:1099/test
user
password
10
1


Thanks,

[roadrunner]

Please use the latest JBoss 2.4.4. This may solve your issue.
This line is wrong if you are using 2.4.x:
org.opentools.minerva.jdbc.xa.wrapper.XADataSourceImpl

It should be:
org.jboss.pool.jdbc.xa.wrapper.XADataSourceImpl

HTH
Sven

[roadrunner]

Afer looking at your last post I noticed that you specified port 1099 for mysql.
Are you really really sure that mysql is running on this port ?
Port 1099 normally is used by jboss/rmiregistry.

bye
Sven

[hemalshah]

sorry roadrunner, that was my mistake! In the JBoss.jcml file I do not specify the port. It simply reads:


org.gjt.mm.mysql.Driver,org.hsql.jdbcDriver,org.enhydra.instantdb.jdbc.idbDriver



org.opentools.minerva.jdbc.xa.wrapper.XADataSourceImpl
mySQL
jdbc:mysql://localhost/test
user
password
10
1

I have a similar problem where JBoss seems to hang when starting up. I'm using JBoss2.4.3 and mysql 11.13 on Redhat. I want to use mysql as the transactional datasource in JBoss and I think I've gotten close. However, running $JBOSS_DIST/bin/run.sh, I do not get any messages that any beans have been deployed (there are ejb-jars in the /deploy dir). Also, when trying to go to "http://localhost:8083/" a blank scrren returns instead of a page listing JBoss' MBeans. Any hints?

I changed the JBossCX(Minerva) and JDBC sections in the jboss.jcml file(tailored server.log file was too big to post):

1. ==>JDBC Section

org.gjt.mm.mysql.Driver



DefaultDS
org.jboss.pool.jdbc.xa.wrapper.XADataSourceImpl

jdbc:mysql://localhost:3306
1200000

10



2.==>Minerva Section

MinervaXADS

org.gjt.mm.mysql.Driver

[adrian.brock]

Without delving too deeply into your configurations.
I have seen this before.

There is a known problem here. An error in
configuration can lead to a hang rather than an
exception. This is probably a JDK bug????

I had this problem myself this hsqldb. I could start
JBoss as root but not under a normal profile. This
was an authority problem.

Somebody else reported it with postgres. It turned out
they didn't have the driver in their classpath
i.e. lib/ext.

I think you meant 8082 for the JMX adapter:-)

Regards,
Adrian

[roadrunner]

@all
Here is a tip that may solve some issues:
Do not omit the default values in the datasource config because sometimes jboss simply refuses to work if you're too minimalistic.

@Hemal:
Did you try to change the DataSourceClass ?

@Twashing:
I think you must not specify the RawXADataSourceLoader because MySQL does not support real XA-Transactions (hey, even transaction support is quite new).

bye
Sven

[twashing]

I've tried my configuration a couple of ways now. Does anyone have a working JBoss2.4.3/MySQL setup. And if so, what needs to be set?

I've started MySQL, then start JBoss. From what I understand, the file that MUST be edited is the jboss.jcml file. Is there something else to be done? How are other people doing this?

tim

[hemalshah]

I have finally been able to configure mySQL to work with JBoss. It turned out that after I made the permission changes in the database and also changed the username + password settings in the jboss.jcml file, JBoss did not recognise these changes. So I decided to do a clean install and that worked!

Thanks for your help everyone.

Tim, what errors do you get?

Hemal

[twashing]

My main error is that no beans seem to get deployed when JBoss starts. There is no stack trace, but with JBoss' default database. I'm used to seeing messages of ejbs being deployed and thier associated tables that get created. The part of the jboss.jcml file that I changed is in my last post (about 3 posts up)

I'll try to reinstall the database, like you did, and running a dead simple ejb client.
