Update the CWSJSON Enterprise Server Region

Start the Server Explorer

Configure CWSJSON resources

To run the invkRevJCICSClientApp Web service requester using the CWSJSON enterprise server region you created in the previous tutorial, you must add the appropriate resources to the startup list and add and configure additional resources required by the CICS program.

Start the CWSJSON enterprise server region

• On the Server Explorer, right-click CWSJSON; then select Start.

Start Enterprise Server Common Web Administration (ESCWA)

• On the Server Explorer, right-click Micro Focus Servers, and then click Administration.

  The ESCWA UI opens in a browser outside of the Visual Studio window.

Access the CICS resource settings for the server

1. After CWSJSON has started, select it from the default Directory Servers list in ESCWA.
2. At the top of the right pane, click CICS > Resources.

Create the CWSJSONR resource group

1. On the RESOURCES page, expand the Groups node.
2. Click NEW in the GROUPS pane.
3. In the Name field, type CWSJSONR.
4. In the Description field, type CICS Web Services JSON Requester Resources; then click SAVE. This invokes the CWSJSONR page where you can create and define resources for the group.

Define resources

The invkRevJCICSClientApp program requires a URIMap resource, a pair of Bundle resources, and a PCT resource used to invoke the Reverse Web service from the Rumba+ TN3270 terminal emulator.

Define a URIMap resource

1. On the CWSJSONR page, click NEW and then click URIMap from the drop-down list.
2. Complete these fields:

   Name	reverseR
   Description	My CICS Requester URIMap
   Usage	Client
   Port	5639
   Host	localhost
   Path	/cics/services/reverse

3. Click SAVE.
4. Click BACK to return to the CWSJSONR page.

Define Bundle resources

1. On the CWSJSONR page, click NEW and then select Bundle from the drop-down list.
2. Complete these fields:

   Name	INVKRVJI
   Description	Input bundle to map the data structure to a JSON request
   Bundle Directory	$IDE_PROJECT_LOC\invkRevJCICSClientApp\invkRevJInBundle

3. Click SAVE.
4. Click BACK to return to the CWSJSONR page.
5. Click NEW and then select Bundle from the drop-down list.
6. Complete these fields:

   Name	INVKRVJO
   Description	Output bundle to map the JSON response to a data structure
   Bundle Directory	$IDE_PROJECT_LOC\invkRevJCICSClientApp\invkRevJOutBundle

7. Click SAVE.
8. Click BACK to return to the CWSJSONR page.

Define a PCT resource

1. On the CWSJSONR page, click NEW and then select PCT from the drop-down list.
2. Complete these fields:

   Name	RVRS
   Description	CWS transaction to invoke the reverse service
   Program Name	invkRevJ

3. Click SAVE.
4. Click BACK to return to the CWSJSONR page.

Open the DEMOSTRT startup list

1. Expand Startup Lists to see the list of CICS STARTUP LISTS.

   The CWSJSON region uses the default startup list, named DEMOSTRT.

2. Click DEMOSTRT.

   This opens the DEMOSTRT page in the right pane.

Add resource groups to the startup list

1. On the DEMOSTRT page under GROUPS, click ADD.
2. On the Available Groups list, check the DFHPIPE, DFHWEB, and CWSJSONRgroups.
3. Click Select.

   This adds all groups to the end of the list.

4. Cllick APPLY.

Install resources

You can install new and changed resources by stopping and starting the region.

• From the Server Explorer in Visual Studio , right-click CWSJSON; then select Restart. This stops and then starts the CWSJSON enterprise server region, automatically installing and loading the newly added resources on the startup list.

Verify Resources

After CWSJSON is started, you can verify that the resources you have defined are installed and active.

1. From the ESCWA UI, click the CWSJSON server in default list.
2. From the CICS drop-down list in the right pane, select Resources.
3. Set the first field to the right of RESOURCES to Active.
4. On the resulting list of active resources, click Bundle. You should see the REQBNDL and RESPBNDL bundles listed and marked as ENABLED.
5. On the list, click URIMap > £map-ref, where map-ref is an alphanumeric string generated by Enterprise Server. You should see the path specified as /cics/services/reverse.

   Enterprise Server generates URIMAPs to provide CICS with the information it needs to process requests. The name of each generated URIMAP begins with a pounds sterling symbol (£).

   To run your provider CICS Web service, you send a JSON request to an endpoint URL that routes the request to your enterprise server region. The endpoint URL contains a URI value. The incoming request reads the installed URIMAPs to identify the map whose Path value matches the URI value of the endpoint URL. When the correct URIMAP is identified, CICS uses the data defined in the URIMAP, such as the name of the Web Service and its associated Pipeline, to process the request.

6. Close ESCWA.
