hi,
in my project i am trying to get an instance of
javax.transaction.UserTransaction in tomcat4.0 using jndi.
i have added the following tag in my server.xml for this regard as well an
appropiate tag for this in WEB-INF/web.xml file which is conatined in my web
application as it is mentioned in the docs of tomcat4.0
<Resource name="jta/UserTransaction" auth="Container"
type="javax.transaction.UserTransaction"/> for server.xml
for web-inf/web.xml following tag is added
<resource-ref>
<res-ref-name>jta/UserTransaction</res-ref-name>
<res-type>javax.transaction.UserTransaction</res-type>
<res-auth>Container</res-auth>
</resource-ref>
when in my JSP application i try to retrieve the instance it throws an
exception on browser that says
Exception Report:
javax.servlet.ServletException: Cannot create resource instance
Root Cause:javax.naming.NamingException: Cannot create resource instance
the code i hve written in jsp page is::
Context ctx1 = new InitialContext();
Context ctx2 = (Context)ctx1.lookup("java:comp/env");
UserTransaction ut = (UserTransaction)ctx2.lookup("jta/UserTransaction");
any idea what shud be done to mend this..
BTW i am using mysql as database and mysql's type 4 jdbc2.0 compliant
driver.
please suggest its urgent..
thanks in advance,
