Hello,

I'm writing a quickstart to show integration of JBoss Transactions, IronJacamar and Tomcat. However, I am a little bit stuck with Postgres xa-datasource. It seams that it is not getting registered correctly. I can successfully access database with local datasource, but I get the following exception when using xa-datasource (exception stack trace available here: http://pastebin.com/vmjHLHX6):

Datasource registration code looks as following (available on github: https://github.com/Gytis/quickstart/blob/master-JBTM-1479/ArjunaJTS/jca-and-tomcat/src/test/java/org/jboss/narayana/quickstart/jca/common/AbstractTest.java):

{code}
// ...
Embedded embedded = EmbeddedFactory.create();
embedded.startup();
embedded.deploy(getURL(JDBC_RAR_FILE_NAME));
embedded.deploy(getURL(POSTGRES_DS_FILE_NAME));
 
Context context = new InitialContext();
DataSource dataSource = (DataSource) context.lookup("java:/PostgresDS");
Connection connection = dataSource.getConnection("postgres", "postgres");
// ... 
{code}

postgres-ds.xml (the one which works) looks as following (available on github: https://github.com/Gytis/quickstart/blob/master-JBTM-1479/ArjunaJTS/jca-and-tomcat/src/test/resources/postgres-ds.xml):

{code:xml}
<?xml version="1.0" encoding="UTF-8"?>

    <datasource jndi-name="PostgresDS" pool-name="PostgresDS">

And finally postgres-xa-ds.xml (the one which does not work) looks as following (available on github: https://github.com/Gytis/quickstart/blob/master-JBTM-1479/ArjunaJTS/jca-and-tomcat/src/test/resources/postgres-xa-ds.xml)

PostgreSQL version used: 9.1

IronJacamar version used: 1.0.15.Final

JDK version used: 1.7

p.s.

username and password does not have to be passed to dataSource.getConnection(), if local datasource is used. However, such invocation will raise an error that password is missing, if xa-datasource is used. (see: datasource registration code).
