Does Infinispan TransactionManagerLookup support WebSphere Liberty?

[RangaJ96]

I was trying to deploy a Java EE application within a WebSphere Liberty BASE server in a Windows environment, within this application I'm using Infinispan as my transactional cache. I faced the following issue when the application tried to access the transactional cache.

java.lang.IllegalArgumentException: Cannot create a transactional context without a valid Transaction instance. at org.infinispan.context.impl.TransactionalInvocationContextFactory.createInvocationContext(TransactionalInvocationContextFactory.java:63) at org.infinispan.context.impl.TransactionalInvocationContextFactory.createInvocationContext(TransactionalInvocationContextFactory.java:57) at org.infinispan.cache.impl.CacheImpl.lock(CacheImpl.java:995) at org.infinispan.cache.impl.CacheImpl.lock(CacheImpl.java:980) at org.infinispan.cache.impl.EncoderCache.lock(EncoderCache.java:307)

Below are the features I have used and my server.xml looks something like the below,

Also, this is the way I configured the Infinispan transactional cache template.

<local-cache-configuration name="local-txn-cache-template"> <locking isolation="READ_COMMITTED" acquire-timeout="15000" concurrency-level="1"></locking> <transaction mode="NON_XA" locking="PESSIMISTIC" transaction-manager-lookup="org.infinispan.transaction.lookup.GenericTransactionManagerLookup" complete-timeout="15000"/> </local-cache-configuration>

Other than that my application getting the following failures in the Infinispan transaction manager lookup stage.

Can anyone verify whether Infinispan supports transactional caching with WebSphere Liberty? Thank you

It looks like the TransactionManager in Liberty needs to be fetched from com.ibm.tx.jta.TransactionManagerFactory. Going to add it to the list of known transaction managers.
In the meantime, you may create a TransactionManagerLookup implementation to fetch the TransactionManager from the correct class. Docs are here: https://infinispan.org/docs/stable/titles/configuring/configuring.html#transaction_manager and an example here: https://github.com/infinispan/infinispan/blob/main/core/src/main/java/org/infinispan/transaction/lookup/WildflyTransactionManagerLookup.java
I hope this helps.

Dear Pruivo, thanks for your help, may I know if is it okay to add the above factory to the TransactionManagerFactory in LookupNames class as below,

@pruivo I applied the above change to the Infinispan and now WebSphere Liberty is able to lookup the transaction manager without any issue, my concern is also solved now. thanks a lot @pruivo.

Thank you for verifying it @RangaJ96
I'm going to add it to Infinispan 14 and Infinispan 15. Tracking JIRA: https://issues.redhat.com/browse/ISPN-15755
