[id="extensions-jms-usage"]
== Usage
[id="extensions-jms-usage-message-mapping-with-org-w3c-dom-node"]
=== Message mapping with `org.w3c.dom.Node`

The Camel JMS component supports message mapping between `jakarta.jms.Message` and `org.apache.camel.Message`. When wanting to convert a Camel message body type of `org.w3c.dom.Node`,
you must ensure that the `camel-quarkus-xml-jaxp` extension is present on the classpath.

[id="extensions-jms-usage-native-mode-support-for-jakarta-jms-objectmessage"]
=== Native mode support for jakarta.jms.ObjectMessage

When sending JMS message payloads as `jakarta.jms.ObjectMessage`, you must annotate the relevant classes to be registered for serialization with `@RegisterForReflection(serialization = true)`.
Note that this extension automatically sets `quarkus.camel.native.reflection.serialization-enabled = true` for you. Refer to the xref:user-guide/native-mode.adoc#serialization[native mode user guide] for more information.

[id="extensions-jms-usage-support-for-connection-pooling-and-x-open-xa-distributed-transactions"]
=== Support for Connection pooling and X/Open XA distributed transactions
ifeval::[{doc-show-extra-content} == true]

[NOTE]
====
Connection pooling is a Technical Preview feature in this release of {project-name}.

To use connection pooling in the `camel-quarkus-jms` components, you must add `io.quarkiverse.artemis:quarkus-artemis` and `io.quarkiverse.messaginghub:quarkus-pooled-jms` to your pom.xml and set the following configuration:
----
quarkus.pooled-jms.max-connections = 8
----
====

endif::[]

You can use the `quarkus-pooled-jms` extension to get pooling and XA support for JMS connections. Refer to the https://quarkiverse.github.io/quarkiverse-docs/quarkus-pooled-jms/dev/index.html[quarkus-pooled-jms] extension documentation for more information.
Currently, it can work with `quarkus-artemis-jms`, `quarkus-qpid-jms` and `ibmmq-client`. Just add the dependency to your `pom.xml`:
[source,xml]
----
<dependency>
    <groupId>io.quarkiverse.messaginghub</groupId>
    <artifactId>quarkus-pooled-jms</artifactId>
</dependency>
----

Pooling is enabled by default.
[NOTE]
====
`clientID` and `durableSubscriptionName` are not supported in pooling connections. If `setClientID` is called on a `reused` connection from the pool, an `IllegalStateException` will be thrown. You will get some error messages such like `Cause: setClientID can only be called directly after the connection is created`
====

To enable XA, you need to add `quarkus-narayana-jta` extension:
[source,xml]
----
<dependency>
    <groupId>io.quarkus</groupId>
    <artifactId>quarkus-narayana-jta</artifactId>
</dependency>
----
and add the following configuration to your `application.properties`:
[source,properties]
----
quarkus.pooled-jms.transaction=xa
quarkus.transaction-manager.enable-recovery=true
----

XA support is only available with `quarkus-artemis-jms` and `ibmmq-client`. Also We highly recommend to enable transaction recovery.

Since there is no quarkus extension for `ibmmq-client` currently, you need to create a custom `ConnectionFactory` and wrap it by yourself. Here is an example:
[source,java]
----
@Produces
public ConnectionFactory createXAConnectionFactory(PooledJmsWrapper wrapper) {
    MQXAConnectionFactory mq = new MQXAConnectionFactory();
    try {
        mq.setHostName(ConfigProvider.getConfig().getValue("ibm.mq.host", String.class));
        mq.setPort(ConfigProvider.getConfig().getValue("ibm.mq.port", Integer.class));
        mq.setChannel(ConfigProvider.getConfig().getValue("ibm.mq.channel", String.class));
        mq.setQueueManager(ConfigProvider.getConfig().getValue("ibm.mq.queueManagerName", String.class));
        mq.setTransportType(WMQConstants.WMQ_CM_CLIENT);
        mq.setStringProperty(WMQConstants.USERID,
            ConfigProvider.getConfig().getValue("ibm.mq.user", String.class));
        mq.setStringProperty(WMQConstants.PASSWORD,
            ConfigProvider.getConfig().getValue("ibm.mq.password", String.class));
    } catch (Exception e) {
        throw new RuntimeException("Unable to create new IBM MQ connection factory", e);
    }
    return wrapper.wrapConnectionFactory(mq);
}
----

[NOTE]
====
If you use `ibmmq-client` to consume messages and enable XA, you need to configure `TransactionManager` in the camel route like this:
[source,java]
----
@Inject
TransactionManager transactionManager;

@Override
public void configure() throws Exception {
    from("jms:queue:DEV.QUEUE.XA?transactionManager=#jtaTransactionManager");
}

@Named("jtaTransactionManager")
public PlatformTransactionManager getTransactionManager() {
    return new JtaTransactionManager(transactionManager);
}
----

Otherwise, you will get an exception like `MQRC_SYNCPOINT_NOT_AVAILABLE`.
====

ifeval::[{doc-show-extra-content} == true]

[NOTE]
====
When you are using `ibmmq-client` and rollback a transaction, there will be a WARN message like:
[source]
----
WARN  [com.arj.ats.jta] (executor-thread-1) ARJUNA016045: attempted rollback of < formatId=131077, gtrid_length=35, bqual_length=36, tx_uid=0:ffffc0a86510:aed3:650915d7:16, node_name=quarkus, branch_uid=0:ffffc0a86510:aed3:650915d7:1f, subordinatenodename=null, eis_name=0 > (com.ibm.mq.jmqi.JmqiXAResource@79786dde) failed with exception code XAException.XAER_NOTA: javax.transaction.xa.XAException: The method 'xa_rollback' has failed with errorCode '-4'.
----
====
 it may be ignored and can be assumed that MQ has discarded the transaction's work. Please refer to https://access.redhat.com/solutions/1250743[Red Hat Knowledgebase] for more information.

[id="extensions-jms-transferexception-option-in-native-mode"]
== transferException option in native mode

To use the `transferException` option in native mode, you must enable support for object serialization. Refer to the xref:user-guide/native-mode.adoc#serialization[native mode user guide]
for more information.

You will also need to enable serialization for the exception classes that you intend to serialize. For example.
[source,java]
----
@RegisterForReflection(targets = { IllegalStateException.class, MyCustomException.class }, serialization = true)
----
