I'm very confused about what you are trying to do and why. Can you
back up and explain your overall strategy here?
I may not understand what you are trying to do but the following
comments might be relevant:
- the tomcat configuration files are mostly ignored in the tomcat
geronimo integration. There are generally geronimo equivalents.
- the geronimo jndi implementation accessible to web apps is read-
only. Only the stuff you specify in web.xml is available, and binding
anything else into it won't work.
- Utilizing an XADataSource directly is not appropriate in a j2ee
application. All the xa stuff is intended to be done for you by the
app server. If you want xa for your application, you need to deploy
an instance of a suitable xa connector. I believe there is a mysql
xa adapter at the tranql project at tranql/vendors/mysql. If this is
in line with what you are trying to do I can try to figure out if it
has been published or more precise download instructions.
thanks

Does MySQL5.0.18 suport XA in Tomcat 5.5 ? I do a XA test in tomcat
with only a jsp file and
necessary jars. The jsp is as:
---------------------------------------------
<%
Context ctx = new InitialContext();
com.mysql.jdbc.jdbc2.optional.MysqlXADataSource xads = new
com.mysql.jdbc.jdbc2.optional.MysqlXADataSource();
xads.setServerName("localhost");
xads.setDatabaseName("test");
xads.setPortNumber(3306);
XAConnection xcon = xads.getXAConnection("root","password");
Connection con = xcon.getConnection();
System.out.println("I get the correct xads and the con=" + con);
System.out.println("Bind xads to InitialContext");
ctx.bind("myXADB", xads);
MysqlXADataSource mysqlXADataSource = (MysqlXADataSource)ctx.lookup
("myXADB");
System.out.println("Get the null MysqlXADataSource from ctx xads="
+ mysqlXADataSource );
%>
---------------------------------------------
Why mysqlXADataSource get from the InitialContext is null ?
Is this why I can not configure the XADataSource in tomcat in the
previous mail ?
I have waste much time in this problem, please help.
Thanks.
