Export SCA composite definitions

We can export information about the definition of a Service Component Architecture (SCA) composite to a file of the choice.

An SCA composite must be a composition unit in a business-level application.

The composite definition provides data on the composite, such as component names and service references. We can view an SCA composite definition in the console or by exporting it to a file . Exporting an SCA composite definition enables you to preserve information about the composite.

This topic describes how to export a composite definition .

We might export a composite definition before updating SCA business-level applications or before migrating to a later version of the product.

1. Start the wsadmin scripting tool.

2. Optional: View online help for the exportSCDL command.

   Jython:

   print AdminTask.help('exportSCDL')

   Using Jacl:

   $AdminTask help exportSCDL

3. Export information about SCA composites in a domain to a file of the choice.

   Use the exportSCDL command to export the information. The command has two parameters, cuName and -exportFile, both of type String. Both parameters are required.

   Using Jython:

   AdminTask.exportSCDL('[-cuName SCA_composition_unit_name -exportFile /my_file]')
   AdminTask.exportSCDL('[-cuName SCA_composition_unit_name -exportFile C:/my_file]')

   Using Jacl:

   $AdminTask exportSCDL {-cuName SCA_composition_unit_name -exportFile /my_file}
   $AdminTask exportSCDL {-cuName SCA_composition_unit_name -exportFile C:/my_file}

   Variable	Description
   $	is a Jacl operator for substituting a variable name with its value
   AdminTask	is an object to run administrative commands with wsadmin.sh
   exportSCDL	is an AdminTask command
   SCA_composition_unit_name	is the name of an SCA composition unit whose information is exported
   /my_file	is the name of the file to which the composite definition is written

Results

After the exportSCDL command runs, information about the composite definition in the SCA domain is written to the specified file. The product displays the following message:

The SCA Composite (SCDL) has been exported successfully.

We can view the same composite definition information in the console. Click Applications > Application Types > Business-level applications > application_name > SCA_deployed_asset_name > View composite.

Example

Suppose the HelloWorldAsync business-level application provided as a sample with the product is installed. Run the exportSCDL command to export the composite definition information for the helloworldws composition unit:

Jython:

AdminTask.exportSCDL('[ -cuName helloworldws -exportFile /my_file ]')

AdminTask.exportSCDL('[ -cuName helloworldws -exportFile C:/my_file ]')

Using Jacl:

$AdminTask exportSCDL{ -cuName helloworldws -exportFile /my_file }

$AdminTask exportSCDL{ -cuName helloworldws -exportFile C:/my_file }

Running the exportSCDL command writes composite definition information resembling the following to the specified file:

<composite xmlns="http://www.osoa.org/xmlns/sca/1.0" targetNamespace="http://helloworld"      name="helloworldws">
     <component name="AsynchTranslatorComponent">        <implementation.java class="helloworld.impl.AsynchTranslatorComponent" />        <service name="AsynchTranslatorService">
        <interface.java interface="helloworld.AsynchTranslatorService"
                callbackInterface="helloworld.HelloWorldCallback"/>                <binding.ws/>
        <callback>
            <binding.ws/>
        </callback>            </service>
    </component>
 </composite>

What to do next

Examine the exported file to ensure that it contains the intended information.
