TransactionManager

doddio Aug 13, 2015 11:13 AM

I'm trying to retrieve the remaining transaction time from com.arjuna.ats.jta.transaction.Transaction.getRemainingTimeoutMills(), but when I attempt to access the TransactionManager I get a NoClassDefFoundError.

In my ejb project's pom.xml I have:

        <dependency>
            <groupId>org.jboss.narayana.jts</groupId>
            <artifactId>narayana-jts-jacorb</artifactId>
            <scope>provided</scope>
        </dependency>

In the ejb project's jboss-deployment-structure.xml I have:

<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="org.jboss.jts" />
        </dependencies>
    </deployment>
</jboss-deployment-structure>

The ejb project is deployed in an ear, which doesn't have a jboss-deployment-structure.xml of its own.

Is it possible to access the TransactionManager from user code under Wildfly, or is that just not allowed? If it's allowed, what am I doing wrong? If there's an alternate approach to getting the remaining transaction time, that would be useful to know too.

Hi,

you maybe need to add the 'narayana-jta' artifact and I think it would be useful to move this topic to narayana forum Narayana

Thanks,

Actually, turns out we have the mvn-ear-plugin generating MANIFEST.MF, so I set it up to add the dependency via our ear's pom.xml:

              <artifactId>maven-ear-plugin</artifactId>
                <configuration>
                    <archive>
                        <manifestEntries>
                            <Dependencies>org.jboss.jts</Dependencies>
                        </manifestEntries>
                    </archive>

Works now!

That's great and can you retrieve the remaining transaction time also by using getRemainingTimeoutMills() ?

Nice. FYI depending on which internals you need to access you may also require the SPI and logging dependencies

<Dependencies>org.jboss.jboss-transaction-spi, org.jboss.logging, org.jboss.jts</Dependencies>

I checked the jboss-transaction-spi and it looks like we do not provide the method to retrieve the transaction remaining timeout. So I assume that it needs to change the spi.

I think it depends on how coupled to Narayana people are prepared to be. Assuming Steven is OK to cast to Narayana class it doesn't need to be in the SPI to work. As you say though, it might be a useful facility to add to the SPI in the future.

Since getting the remaining timeout isn't part of the standards I'm not sure it makes sense in the SPI at the moment - or at least not until we find other implementations provide a similar capability.

I'd like to use getTimeLeftBeforeTransactionTimeout() from TransactionManagerDelegate from the org.jboss.jts.integration module, as it looks to handle transaction states better than using Transaction.getRemainingTransactionTime() directly.

But when I try to use it, I get a NoClassDefFoundError exception again for TransactionManagerDelegate.

I tried adding all of the deps specified in the org.jboss.jts.integration module, but no luck:

<Dependencies>org.jboss.as.transactions, javax.resource.api, javax.transaction.api, javax.api, org.jboss.logging, org.apache.commons.logging, org.jboss.jboss-transaction-spi, org.jboss.jts, org.omg.api, org.jboss.jts.integration</Dependencies>

Anyone have any idea what deps I need, or if I can even import this module? Looks like it's in a folder called "integration" instead of "main", not sure if that makes it unavailable or not...

Hi Steven,

Can you post the stack trace please? I can try it here if you can you post a simple EJB maven project with maybe an @Startup that replicates the issue for us to try it here?

Thanks,
Tom

Never mind.

Turns out we specify our dependencies under Arquillian differently then under our actual EAR, so I just had to add the deps to both locations.

Seems to be working under Arquillian and in proper deployments now.
