Put operation does not work for IBM MQ from camel when using JMSPoolXAConnectionFactory

We are implementing XA transaction between MQ and database and trying to create a connection factory as a service in karaf as per the below link.
https://access.redhat.com/documentation/fr-fr/red_hat_fuse/7.2/html/apache_karaf_transaction_guide/using-jms-connection-factories#manual-deployment-connection-factories
The MQ we are using is IBM and we are connecting to it through camel.
The karaf service is exposed from the same bundle that is going to use it. This is done through blueprint xml file present in the src/main/resources/OSGI-INF/blueprint folder.
When we use (through JNDI) the connection factory exposed as a service for setting the connection factory to be used by the JmsComponent of camel, we are able to get message from the queue but not able to put message into the queue. There is no error when the put operation fails and hence, the database gets updated with success. This happens specifically when using JmsPoolXAConnectionFactory as the pool connection factory. If we change it to JmsPoolConnectionFactory, the put operation works and the message is added to the queue.
Below are the sample routes for get and put to queue.
GET:
from("mq:queue:{{queueName}}")
.process(new CustomProcessor1())
.to("direct:call-sp")
.end();
from("direct:call-sp")
.to("sql-stored:call-sp")
.end();
PUT:
from("vm:send")
.process(new CustomProcessor2())
.to("mq:queue:{{queueName}}")
.to("sql-stored:update-sp")
.to("vm:nextroute")
.end();
Camel JmsComponent Configuration in camel-context.xml:
<reference id="ptm" interface="org.springframework.transaction.PlatformTransactionManager" />
<reference id="connectionFactory" interface="javax.jms.ConnectionFactory" filter="(osgi.jndi.service.name=jms/mq)" availability="optional" />
<bean id="jmsConfig" class="org.apache.camel.component.jms.JmsConfiguration">
<property name="transacted" value="false" />
<property name="connectionFactory" ref="connectionFactory" />
<property name="transactionManager" ref="ptm" />
</bean>
<bean id="mq" class="org.apache.camel.component.jms.JmsComponent">
<property name="configuration" ref="jmsConfig" />
<property name="destinationResolver" ref="customDestinationResolver" />
</bean>
<bean id="customDestinationResolver" class="com.example.CustomDestinationResolver">
</bean>
Is there any put related specific configuration that we are missing?

To coordinate XA transactions, you need a transaction manager which implements the Java Transaction API (JTA).
Therefore, I think you need to use a JtaTransactionManager rather than a org.springframework.transaction.PlatformTransactionManager.

Getting IgniteCheckedException: Default Ignite instance has already been started exception when enabling Persistence on single Node

I am deploying an application where I need to maintain some data in Ignite cache. I used in memory Ignite cache. Here is the Ignite configuration I have used:
<property name="cacheConfiguration">
<list>
<bean
class="org.apache.ignite.configuration.CacheConfiguration">
<property name="name" value="IGNITE_DATA" />
<property name="cacheMode" value="PARTITIONED" />
<property name="atomicityMode" value="ATOMIC" />
<property name="writeSync"
value="PRIMARY_SYNC" />
<property name="backups"
value="${IGNITE_CACHE_BACKUPS}" />
</bean>
</list>
</property>
Now when I deployed multiple instances of my application and stored data in Ignite cache. Its shared among all the application instances.
Even if any any instance goes down and comes up after sometime it has the latest data via Ignite cache sync.
But issue occurs when all the application instances go down. When they come up data is gone since it was not persisted. For persistence I used dataStorageConfiguration property and enabled the persistence. Here is the change I added to Ignite configuration:
<property name="dataStorageConfiguration">
<bean
class="org.apache.ignite.configuration.DataStorageConfiguration">
<!-- Enabling Apache Ignite Persistent Store. -->
<property name="defaultDataRegionConfiguration">
<bean
class="org.apache.ignite.configuration.DataRegionConfiguration">
<property name="persistenceEnabled" value="true" />
</bean>
</property>
<!-- Changing Write Ahead Log Mode. -->
<property name="storagePath" value="${IGNITE_BC_STORE_PATH}"/>
<property name="walMode" value="LOG_ONLY" />
</bean>
</property>
Now when I deploy my application and I try and start Ignite from Java code as mentioned below:
log.info("Initializing IGNITE...");
ignite = Ignition.start(getClass().getResource(CONF_FILE));
I get an exception every time stating the default instance has already started.Tried several things but didn't work. Even if I remove the CacheConfiguration from Ignite Configuration and just keep dataStorageConfiguration I still getting the same error. Error is :
Caused by: class org.apache.ignite.IgniteCheckedException: Default Ignite instance has already been started.
at org.apache.ignite.internal.IgnitionEx.start0(IgnitionEx.java:1141)
at org.apache.ignite.internal.IgnitionEx.startConfigurations(IgnitionEx.java:1076)
at org.apache.ignite.internal.IgnitionEx.start(IgnitionEx.java:962)
at org.apache.ignite.internal.IgnitionEx.start(IgnitionEx.java:881)
at org.apache.ignite.Ignition.start(Ignition.java:373)
Normally this error comes when we try and run multiple Ignite nodes under same JVM but here I am running single node per JVM. Then also getting the error.
Please do correct me if I am wrong.
Any help here will be appreciated.

Most probably, you have more than one IgniteConfiguration bean in your config file. If one configuration bean extends another one, then make sure, that the parent is abstract.

I have resolved the issue. Seems like the issue was not woth the Ignite configuration but was with Spring Framework configuration.
I was creating the bean for the Ignite class using the lazy-init=true. I switched that to the eager-init and that resolved my issue.
Not sure how exactly it solved this but it worked at least in my case.

How can I implement a socket reconnection using spring integration TCP?

While integrating to a TCP endpoint, we created an application using Spring integration TCP where we've a pooled connection using the following beans:
<!-- Pooled Connection factory -->
<int-ip:tcp-connection-factory id="client" type="client" host="${gateway.url}" port="${gateway.port}"
single-use="true" so-timeout="${gateway.socket.timeout}" serializer="appSerializerDeserializer" deserializer="appSerializerDeserializer" />
<bean id="cachedClient" class="org.springframework.integration.ip.tcp.connection.CachingClientConnectionFactory">
<constructor-arg ref="client" />
<constructor-arg value="${gateway.pool.size}" />
</bean>
Does anyone have a suggestion on how to implement a socket re-connection in case a socket loses the connection?

It will automatically reconnect the next time you send something.

How to increase Apache CXF timeout using XML configuration and JaxWsProxyFactoryBean?

I am using apache CXF implementation of JAX-WS.
My web service is configured via spring xml configuration using JaxWsProxyFactoryBean:
<bean id="myWSClient" class="my.package.MyWSClient"
factory-bean="clientFactory"
factory-method="create" />
<bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
<property name="serviceClass" value="my.package.MyWSClient"/>
<property name="address" value="http://some.url"/>
</bean>
and later I am injecting it via:
#Resource(name = "myWSClient")
MyWSClient myWSClient;
How I can manage to increase timeout for MyWSClient?

To configure client timeouts using spring configuration use this:
<http-conf:conduit name="*.http-conduit">
<http-conf:client
ConnectionTimeout="600000"
ReceiveTimeout="600000"/>
</http-conf:conduit>
In this example timeout for response and connection is setup for 600 seconds.

CXF Web Service JMX Port Assignment

We have many CXF web services running under Tomcat. For each of the services, there is a beans config file, with each one having an entry like the one below. The variable ${JMX.PORT} is replaced with the assigned port at runtime. Each service has a separate port. I have looked everywhere but cannot confirm that this is correct. I do know, however, that having the same port for two or more services causes startup issues. So, I am looking for confirmation that each service should have its own port. Note - When I look at a service remotely using JConsole, with a connection string such as service:jmx:rmi:///jndi/rmi:/192.168.29.35:9912/jmxrmi, I can also see the other services, even though they have different port assignments. That makes no sense, unless there are some kind of shared resources. Can anyone help me to understand this? Thanks!
