[JBoss-user] [Persistence, JBoss/CMP, Hibernate, Database] - how to change hibernate bytecode provider

2006-06-02 Thread teknokrat
the version of hibernate used in jboss 4.0.4 is 3.2 which allows pluggable 
bytecode providers. Currently it defaults to javassist. How can i change this 
to cglib?

thanks

I have a hibernate project that i can deploy to jboss 4.0.3SP1 with no 
problems. When I try to deploy it to 4.0.4GA I get Enhancement failed errors

Its hard to reproduce everything since its already a complete application

A simple example is the Company class, mapped as


  | class name=Company table=company
  | id name=id type=integer
  | generator class=native /
  | /id
  | property name=name /
  | property name=enabled type=boolean /
  | 
  | set name=applications table=app inverse=true 
  | key column=company /
  | one-to-many class=Application/
  | /set
  | 
  | /class
  | 

the stack trace is

We have the same problem, JBoss 4.03SP1 on Windows 2003 Server using Java 5. 
The only thing I can pin it on is this hotfix

http://support.microsoft.com/?kbid=908531

which is all thats changed on the server. The stupid thing is that its just the 
one node. The other two nodes both had the hotfix applied but seem fine.

I am willing to provide more information if it will help nail this problem.

After using a different partition name and restarting the nodes everything is

[JBoss-user] [Clustering/JBoss] - JBoss problem with latest windows hotfix

2006-02-16 Thread teknokrat
This just happended to our testing cluster. It probably deserves a JIRA issue 
but I am not sure how reproducible it is.

We are using JBoss 4.0.3. SP1 on Windows 2003 Server. Today we updated our 3 
node cluster with this hotfix KB913446. For some reason only two machines ( 1 
and 3) were updated. Suddenly they started throwing


  | 2006-02-16 11:13:15,802 WARN  [org.jgroups.protocols.pbcast.ClientGmsImpl] 
handleJoin(t01:1139) failed, retrying
  | 

Rebooting, restarting, etc didn't stop this. Nor did removing 
cluster-service.xml. JBoss was NOT accepting any connections so the machines 
were unusable.

After rebooting machine 2 which did not have the hotfix applied, everything 
returned to normal. We'll be monitoring this for a while of course.

I hope its just a one off gremlin.

I have built a web service client using axis. Unfortunately, i come across this 
issue on redeployment of my jar http://jira.jboss.com/jira/browse/JBAS-2160.

Is there a fix for this yet, or maybe a workaround?

[JBoss-user] [Clustering/JBoss] - Re: Nodes having difficulty discovering each other

2005-11-23 Thread teknokrat
I've rechecked the config files again. Both cluster-service.xml and 
tc5-cluster.xml have the same config on both machines and furthermore this is 
identical to the default config i.e. I have not changed anything except set 
loopback=true because these are windows machines.

The ethereal output above is from 10.21.201.18 which shows its sending out UDP 
packets. The log for 10.21.201.17 was identical. UDP packets were being sent 
but not received. At least not from another machine. Do you need to see more 
ethereal output? i figured only the UDP part would be interesting but perhaps 
other protocols matter too. I was seeing a lot of TCP bad checksum errors!

[JBoss-user] [Clustering/JBoss] - Nodes having difficulty discovering each other

2005-11-22 Thread teknokrat
This is my setup. I am building a 4 node cluster. I have tried jboss 4.03 and 
4.03sp1. The machines are windows 2003 servers and the jvm is java 5. 
Everything has been updated. I am using the default cluster-service.xml. All 
the machines are on the same network segment, no firewalls are in place. The 
machines can all see ( ping) one another.

The problem I am having is that the nodes are not discovering each other. 
Sometimes, three of the nodes form a group but this process takes a while. The 
4th node never gets detected. The network settings of the machines are 
identical. I have tried using ViewDemo - the results are the same. I have setup 
multicast receiver/sender pairs and the reception is sporadic. I have run  the 
Draw demo and I do not get any communication between the instances.

To add insult to injury, I have setup a similar cluster for another company 
which worked 'out of the box'. I am not a network engineer so I have no idea 
what i can troubleshoot to fix this problem. Likewise, the network engineer 
knows nothing about jboss clustering so doesn't know what settings to check.

Can anyone offer some advice of what i can do to help troubleshoot this issue. 
I am logging all of jgroups at trace level but I am not seeing anything that 
looks like a problem. What network settings should I get the network engineer 
to examine that would affect the multicast traffic between the machines?

thank you

[JBoss-user] [Clustering/JBoss] - Re: Nodes having difficulty discovering each other

2005-11-22 Thread teknokrat
yes, I've tried this.

1. I have set up the ViewDemo test on all machines. Eventually ( like after 
half an hour ) three of the nodes are recognised as a cluster group. The fourth 
node is never detected.

2. I have set up a multicast receiver/sender pair on the nodes and have sent 
messages. Not all messages are received. Reception is sporadic but does occur 
on all nodes.

3. i have set up the Draw test on the nodes. Cannot get it to work. Drawing on 
one node never duplicates across to another node.

I would like to reiterate that I doubt very much that this is a jgroups 
problem. I have set up the same configuration elsewhere and everything works 
ok. I have scanned the machines and ports 45566, 45577 show up as open.

Are there any network settings that can affect multicast packets? Can any other 
devices interfere with the process of discovery. I know that there is a DB 
cluster on this network using windows clustering.

2005-08-24 Thread teknokrat
Just to provide some details. I am using jboss 4.02 and the code for getting 
the ejb is 

Object ref = context.lookup(jndiName);
EJBHome home = (EJBHome) javax.rmi.PortableRemoteObject.narrow(ref, klass);

I have tracing on so I know that the system behind the firewall does receive 
the initial request on port 1100. 

So why is my ejb not bound when i use hajndi?

cheers

[JBoss-user] [Clustering/JBoss] - getting remote ejb across firewall

2005-08-23 Thread teknokrat
I am trying to obtain a remote reference to an ejb in one jboss cluster from 
another. They are separated by a firewall. I have opened ports 1099, , 1100 
between them. 

The normal lookup on port 1099 works ok. However, when I try to use the HAJNDI 
port 1100 I get that the ejb is not bound naming exception. I assumed that this 
was because I had to set a new RmiPort and RmiObjectPort for HAJNDI to use. So 
I set these to 1199 and 1144 in cluster-service.xml and opened those ports. 
Nothing changed. 

I assume I am missing one or more ports that need opening but I can't figure 
out which ones from the documentation. Can someone tell me what i am missing 
please.

thank you

5. Have a HA-Singleton service manage file updates/additions. other nodes can 
use this if they don't have a local cached copy

[JBoss-user] [Clustering/JBoss] - how to make external data available to a cluster

2005-07-14 Thread teknokrat
I have an app running on a JBoss 4.02 cluster. A requirement of this app is 
that it must serve various files to clients. The files are mostly 60-80K, but 
there are a lot of them and they will be changed/added regularly. I have a 
number of possible solutions in mind but would like to hear what other people 
do in such situations.

1. Have a server set up as a content repository, Place files on it and have the 
cluster query this machine, making local copies if necessary.

PROS: Simple to set up and control
CONS: introduces SPOF, could lead to a bottleneck

2. Place files in JBoss farm directory and have JBoss far them out to other 
nodes. Use a background process ( maybe a custom deployer? ) to register chages 
and inform the app.

PROS: uses current JBoss processes
CONS: Leads to messy deploy directory ( maybe canbe cleaned up by making copies 
elsewhere?? ), ...

3. Place files as BLOBs in a DB.

PROS: simple, especially if using hibernate with JBossCache
CONS: Potential performance issues, dealing with BLOBs issues, ... ?

4. Let users upload files using a web interface. Store files in JBossCache and 
let it manage them.

PROS: Gives users control of their files
CONS: memory issues?, how do i organise these files, what if iwant query the 
number of files of a particular type in the system

Does anyone have ideas what a good solution would be? Anyone have any comments 
to make about any of the above possible solutions?

thanks

Also, make sure netbios is switched off. Especially if there is firewall 
between your servers. Windows send UDP broadcasts to find other machines if 
netbios is enables, which, if the firewall block them can lead to 2-3 sec delay.

[JBoss-user] [Beginners Corner] - Strange behaviour making connection from client

2005-06-13 Thread teknokrat
I have a simple servlet that makes a connection to a jboss 4 instance on 
another server. The strange thing is, is that before each connection attempt it 
sends out several UDP packets including some to the broadcast address. Since i 
have provided the url to the jboss server i.e. jnp://server:1099  and all the 
relevant ports are open ( 1098, 1099, , 4445 ) I fail to understand why 
this is happening. The two machines are on different network segments separated 
by a firewall. I'd like to think that this is just due to some misconfigured 
network settings but I am at a loss as what they could be.

Does anyone know?

The design we are trying to implement has a couple of load balanced tomcats in 
the DMZ talking to a couple of clustered JBoss 4.02 servers on the backend. 
What I am a bit lost on is setting up the jndi on the tomcats to communicate 
with JBoss and have everything load balanced with failover.

Is my understanding correct that if I do not provide a provider url then the 
client will auto discover the jboss cluster? Is there a performance penalty for 
doing things this way? Will access to the jboss cluster be load balanced?

If anyone can comment on this or point me to some pertinent docs I would really 
appreciate it ( yes, I have been reading the manual )

thank you

[JBoss-user] [Clustering/JBoss] - Re: Clustering Confusion

2005-03-11 Thread teknokrat
Yeah, I've been at looking at it. What I don't understand is where the MDBs 
come into it. Does it mean the MDBs reside on the same servers as the JMS 
queue/topic? If so, how is load balancing handled?

There is an example onthe wiki on  Load-balanced, faul-tolerant MDBs in HAJMS 
which I am reading now. Are there any other sources of information on this 
topic?

thanks

[JBoss-user] [Clustering/JBoss] - Clustering Confusion

2005-03-10 Thread teknokrat
After reading what I coulkd find on jboss clustering I am still apprehensive 
about ceratin details involving clusterin message driven beans.

Our situation is that we have a jboss 4.01 cluster on windows 2003 server. We 
have a layer of tomcat instances with load balancing that call stateless 
session beans on jboss cluster. We want to migrate this to an architecture that 
has a layer of clustered jms queue/topics and a layer of clustered mdbs.

1. Is this possible or am I mad.
2. The docs give me the impression that mdb clustering is not implemented in 
jboss. If so, what do I do? Can I create my own HA-MDB Singleton and deploy in 
on the mdb cluster?
3. We are currently considering using Queues to push messages to the mdbs. 
Would it be better if the mdbs subscribed to topics instead?
4. Anything else I might have missed.

Sorry if some of the above sounds dumb, I am quite new to this.

thanks

[JBoss-user] [Installation Configuration] - Re: MissingResourceException with JBoss 4.01

2005-02-03 Thread teknokrat
what LANG variable? I'm on windows 2K. Also, the en_GB setting is correct - I 
am in the UK. I don't want to reset the computer's region settings.

I have just downloaded jboss 4.01 and unpacked it. I am using jdk1.5.0. When I 
run run.bat I get

at java.util.ResourceBundle.throwMissingResourceException(ResourceBundle
.java:837)

Is there something else I forgot to do?
