# Configuring XA Transactions in JMS Connector

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

Anypoint Connector for JMS (JMS Connector) provides the option to use Extended Architecture
Transactions (XA Transactions) when you configure the **XA Connection Pool** and the **Transaction
Type** fields.

## Before You Begin

Before getting started, ensure that you have an understanding of
[XA Transactions](https://docs.mulesoft.com/mule-runtime/latest/xa-transactions).

## Configure XA Transactions

To configure XA transactions, follow these steps:

1.  In your **JMS Config**, configure the **XA Connection Pool** fields for **Min pool size**, **Max
    pool size**, and **Max idle seconds**:

```xml
 <jms:config name="JMS_Config">
        <jms:active-mq-connection brokerURL="tcp://localhost:61616"
                                  userName="admin"
                                  password="admin">
            <jms:xa-connection-pool minPoolSize="1"
                                    maxPoolSize="10"
                                    maxIdleSeconds="45"/>
        </jms:active-mq-connection>
    </jms:config>
```

2.  Configure the **JMS Listener** source **XA Transaction** field to `XA`:

```xml
</flow>
    <flow name="JMS_Listener_Flow">
        <jms:listener
                destination="queue.in"
                config-ref="JMS_Config"
                transactionType="XA"
                transactionalAction="ALWAYS_BEGIN">
            <ee:transform>
                <ee:message>
                    <ee:set-payload><![CDATA[%dw 2.0
output application/json
---
payload]]></ee:set-payload>
                </ee:message>
            </ee:transform>
        </jms:listener>
        <vm:publish config-ref="VM_Config"
                    queueName="queue"
                    transactionType="XA"
                    transactionalAction="ALWAYS_JOIN"/>
    </flow>
```

In the **Configuration XML** editor window, the Mule app configuration looks like this:

```xml
