Configuring arjuna transactions

ivanovan Nov 7, 2012 12:44 AM

I'm using narajana-jta-5.0.0.M1 library(jar) in my project. Not whole jboss server only this library for transactions. I would like to make my own configuraion file for transactions. For example to change ObjectStore folder. It's important that this config file should be outside the arjuna jar. I found out that if a set -Dcom.arjuna.ats.arjuna.common.propertiesFile to my config file everything should work. I've added this and made my own configuration file. In debug a see that file is read and I'll get my new properties from this file. there are going to initialize and I see how the new ObjectStrore appeares. But in next steps it's gone and chenged to default objectStore folder. So as I can understand properties are overwritten. P.S. My config file lokks the same as one in arjuna jar. Named jbossts-properties.xml Only one line is different: \MyStore.

Need help in using my own configuration file or maybe explaining my mistake.

Hi Andrew,

Arjuna is modular. I think what is happening is that you have ommitted setting one of the other named object stores (in this case the communicationStore) and this is confusing you.

I have just pushed a test that I used to verify this, to see it:
https://github.com/jbosstm/narayana/blob/master/ArjunaJTA/jta/src/test/resources/jbossts-properties.xml
https://github.com/jbosstm/narayana/blob/master/ArjunaJTA/jta/tests/classes/com/hp/mwtests/ts/jta/basic/JTATest.java

Note, in the debugger you will see some getObjectStoreDir calls with the default value but these are then overwritten by setObjectStoreDir calls with the values you set.

If you are still having trouble, the app server also configures: ObjectStoreEnvironmentBean.stateStore.objectStoreDir, but I did not need to.

Thanks a lot!
<entry key="ObjectStoreEnvironmentBean.objectStoreDir">/fold1/</entry> - this works!
Maybe you can help me in resolving one more problem.
So now I have my own jbossts-properties file. How can I configure logging. To specify my own log file.
In my log I see some string from arjuna, like: ARJUNA12130: Name of XA node not defined. Using Arjuna:53524
I can't change log4j.properties inside arjuna jar. And in my project I've got my own log4j.properties.
As I can find
<entry key="com.arjuna.common.util.logging.DebugLevel">0xffffffff</entry>
this key should turn on the debug level and I should see some trace, but nothing happened.
than I tried:
<entry key="com.arjuna.common.internal.util.logging.LoggingEnvironmentBean">0xffffffff</entry>
<entry key="com.arjuna.common.internal.util.logging.BasicLogEnvironmentBean">0xffffffff</entry>
But no influence. Nothing happened.
Maybe this doc http://docs.jboss.org/jbosstm/5.0.0.M1/guides/development_guide/chap-configuration-options.html
can be a little bit more informative.

Hi Andrew,

We are using JBoss Logging these days so you can configure it as per the JBoss Logging mechanisms available.

For example, if you provide log4j on the classpath then you should be able to configure JBTM using a standard log4j configuration file.

Hope that helps,
Tom
