How to archive Exception Handling in Application level  ?????????????

SCA is very important in terms of SOA Application ( Composite.xml )

Composite.xml :

Add following piece of code inside composite.xml


 <property name="oracle.composite.faultPolicyFile">fault-policies.xml</property>
 <property name="oracle.composite.faultBindingFile">fault-bindings.xml</property>


Fault Handlining :

1. Fault-bindings.xml


<?xml version="1.0" encoding="UTF-8" ?>
<faultPolicyBindings version="2.0.1" xmlns="http://schemas.oracle.com/bpel/faultpolicy"
xmlns:xsi="http://www.w3.org/2001/XMLSchemainstance">
<composite faultPolicy="KrishnaFaults"/>
</faultPolicyBindings>


2. Fault-policies.xml

<?xml version="1.0" encoding="UTF-8" ?>
<faultPolicies xmlns="http://schemas.oracle.com/bpel/faultpolicy">
  <faultPolicy version="2.0.1" id="KrishnaFaults"
               xmlns:env="http://schemas.xmlsoap.org/ soap/envelope/"
               xmlns:xs="http://www.w3.org/2001/XMLSchema"
               xmlns="http://schemas.oracle.com/bpel/faultpolicy"
               xmlns:xsi="http://www.w3.org/2001/ XMLSchema-instance">
   

 <Conditions>
          <faultName xmlns:bpelx="http://schemas.oracle.com/bpel/extension"
                 name="bpelx:remoteFault">
        <condition>
          <action ref="ora-retry"/>
        </condition>
      </faultName>
    </Conditions>


    <Actions>
      <Action id="my-java-handler">
        <javaAction className="soatraining.faulthandling. MyFaultHandler"
                    defaultAction="ora-terminate" propertySet="myProps">
          <returnValue value="OK" ref="ora-rethrow-fault"/>
        </javaAction>
      </Action>

      <!-- Retry -->
      <Action id="ora-retry">
        <retry>
          <retryCount>4</retryCount>
          <retryInterval>2</retryInterval>
          <exponentialBackoff/>
        </retry>
      </Action>

      <!-- Rethrow action -->
      <Action id="ora-rethrow-fault">
        <rethrowFault/>
      </Action>
      <!-- Human Intervention -->
      <Action id="ora-human-intervention">
        <humanIntervention/>
      </Action>
      <!-- Terminate -->
      <Action id="ora-terminate">
        <abort/>
      </Action>
    </Actions>
    <Properties>
      <propertySet name="myProps">
        <property name="logFileName">myfaulthandler.log</property>
        <property name="logFileDir">c:\temp</property>
      </propertySet>
    </Properties>
  </faultPolicy>
</faultPolicies>




Conditions and Action are very important in Fault-policies.xml.
