If you are testing retry actions on adapters with both JCA-level retries for the outbound direction and a retry action in the fault policy file for outbound failures, the JCA-level (or binding level) retries are executed within the fault policy retries. For example, assume you have designed the application shown in Figure 12-22:

You specify the retry parameters, as shown below, in the composite.xml file:

<property name="jca.retry.count" type="xs:int" many="false"
  override="may">2</property>
<property name="jca.retry.interval" type="xs:int" many="false"
  override="may">2</property>
<property name="jca.retry.backoff" type="xs:int" many="false"
  override="may">2</property>

In the fault policy file for the EQ reference binding component for the outbound direction, you specify the actions shown in the following code:

<retryCount>3</retryCount>
<retryInterval>3</retryInterval>

If an outbound failure occurs, the expected behavior is for the JCA retries to occur within the fault policy retries. When the first retry of the fault policy is executed, the JCA retry is called. In this example, a JCA retry of 2 with an interval of 2 seconds and exponential back off of 2 is executed for every retry of the fault policy:

• Fault policy retry 1:

  • JCA retry 1 (with 2 seconds interval)

  • JCA retry 2 (with 4 seconds interval)

• Fault policy retry 2:

  • JCA retry 1 (with 2 seconds interval)

  • JCA retry 2 (with 4 seconds interval)

• Fault policy retry 3:

  • JCA retry 1 (with 2 seconds interval)

  • JCA retry 2 (with 4 seconds interval)
