Hi all
Resin 4.0.33 and Weblogic compatibility issue
==================================================== We are facing
compatibility issue with Resin 4.0.33 and weblogic 10.3.0 in the user
transaction commit context. The exception we get at weblogic side is as
below. " javax.transaction.SystemException: Could not contact
coordinator at mslv02+10.5.177.159:8004+m62domain+t3+" from the
weblogicfullclient generated from the server and given to us. Please help
us understandning any Enterprise Bean compatibility issue between Resin
4.0.33 and Weblogic version: 10.3.0, specific to transaction. The
details are explained below. Requirement: In transaction mode, save the
set of db operation and commit. (Note: The exercise was done both cluster
mode weblogic server and standalone mode and got the same exception. What
does the code do: ===================== 1. The Local application CygNet
deployed in Resin 4.0.33 with IBM JDK. 2. The functional module will take
a set of data to be updated/added/deleted in the database via EJB call
provided by application Metasolv deployed in Weblogic server and the
version details are mentioned below. 3. To make the DB operation javax
implementation of Usertransaction is used and the flow is as below.
- Get the InitialContext() for the weblogic server security credentials
and URI(use t3 protocol). - Get the connection using jndiTemplate.
- Start the Transaction. - Do the Update operation using the
provided API. - Commit the transaction. - Close the
connection. - In case Exception, Rollback the transaction. The
code snippet to understand more is as below: Context: <bean
id="m6JndiTemplate"
class="org.springframework.jndi.JndiTemplate"> <property
name="environment"> <props> <prop
key="java.naming.factory.initial">weblogic.jndi.WLInitialContextFactory</pro
p> <prop key="java.naming.provider.url">#{'t3://' +
m6Config.getProperty('IP_ADDRESS') + ':' +
m6Config.getProperty('PORT')}</prop> <prop
key="WLContext.ENABLE_SERVER_AFFINITY"></prop>
</props> </property> </bean> <bean
id="userTransaction"
class="org.springframework.ejb.access.SimpleRemoteStatelessSessionProxyFacto
ryBean"> <property name="jndiName"
value="javax.transaction.UserTransaction" /> <property
name="jndiTemplate" ref="m6JndiTemplate" />
<property name="businessInterface"
value="javax.transaction.UserTransaction" /> </bean>
Note: We used "weblogic.transaction.UserTransaction"
also which is same as javax implementation, I believe. Code:
userTransaction.setTransactionTimeout(3600);
userTransaction.begin(); try{
for(UpdateElement e:listOfElement){ write(e);
} userTransaction.commit();
} catch (Exception e) {
userTransaction.rollback(); } 4. The above
were worked perfectly with out any problem while we deployed in the
"deployment scenario:1" mentioned below. "deployment
scenario:1":Compatible and working 1. Resin 4.0.33 ( Local server) 2.
Weblogic version: 8.1.5 (Local Client and remote server) 3. IBM jdk 1.6.0
(SR5),J2RE. 4. Oracle database 10.2.0.5.0 g 5. Spring 3.1.4
"deployment scenario:2":Not working Later some point of time,
the weblogic server was upgraded to newer version and application to have
Security principal details. 1. Resin 4.0.33 ( Local server) 2. Weblogic
version: 10.3.0 3. IBM jdk 1.6.0 (SR5),J2RE. 4. Oracle database 11.2.0.3.0
db11g 5. Spring 3.1.4 Now the application is throwing the exception while
we "Commit the transaction" "
javax.transaction.SystemException: Could not contact coordinator at
mslv02+10.5.177.159:8004+m62domain+t3+" from the weblogicfullclient
generated from the server and given to us.
