Walks you through the steps required to update the
CWSJSON
enterprise server region to run the
LOANPAYM Web service.
Configure the
enterprise server region
This tutorial uses the
CWSJSON
enterprise server region created in
Tutorial: CICS Web Service Provider from JSON, Top-down Method to run the Web service provider.
Do one of the following:
- If you did not complete
Tutorial: CICS Web Service Provider, JSON Request-Response Top-down Method:
- Open the
Set Up the
CWSJSON
Enterprise Server Region topic.
- Complete the sections titled
Create the
CWSJSON
enterprise server region and
Configure
CWSJSON
resources. However, when selecting a project with which to associate the new region, check the
LoanJSON project instead of the
ReverseJSON project.
- From that point, proceed directly to the
Verify Resources section later in this topic.
- If you did complete
Tutorial: CICS Web Service Provider, JSON Request-Response Top-down Method, then you created and configured
CWSJSON
at that time. In this case, perform the steps presented in this section before moving on to the
Verify resources section.
- Update the
dfhdrdat file
- When you create an
enterprise server region from the
Server Explorer, it stores some configuration information in the project's
system\dfhdrdat file. Therefore, to update the
LoanJSON project with this information, you can copy the file from the
ReverseJSON project to the
LoanJSON project:
- Using Windows
File Explorer or at a command prompt, copy the
dfhdrdat file located in the ReverseJSON project's
system directory to the
LoanJSON project's
system directory, overwriting the existing file.
- Start the Server Explorer
- The
Server Explorer expandable ribbon is visible in Visual Studio on the top left side of the IDE by default when using
Enterprise Developer. However, if it is not visible:
- In Visual Studio, click
View > Server Explorer.
Attention: You might encounter an
Enterprise Server Sign On dialog box as you perform the steps required to create, configure, start, or stop an
enterprise server instance from the
Server Explorer. If you do, ensure that the
Server requires credentials,
Use specific server credentials, or
Server is secured
box is
unchecked, and then click
OK.
Also, if prompted to disable password recovery, click
No.
- Associate the
LoanJSON project
- In previous tutorials, you have associated your project with an
enterprise server region as part of the steps to create the region. Because the region you are using here was previously associated with the ReverseJSON
project, you need to change the association to the
LoanJSON project.
- On the
Server Explorer, right-click
CWSJSON; then select
Associate with project.
- If a check mark appears next to
ReverseJSON, click it to remove the association.
- Again, right-click
CWSJSON; then select
Associate with project.
- Click
LoanJSON to create an association.
- If you are prompted to restart the server, answer
Yes; if you are not prompted, right-click
CWSJSON and select
Start from the context menu.
Verify resources
After
CWSJSON is started, you can verify that the resources you have defined are installed and active.
- Start
Enterprise Server Common Web Administration (ESCWA)
-
- Access the CICS resource settings for the server
-
- After
CWSJSON has started, select it from the default
Directory Servers list in ESCWA.
- At the top of the right pane, open the drop-down menu next to
CICS.
- View defined resources
-
- From the
CICS drop-down list in the right pane, select
Active under
Resources.
- On the resulting list of active resources in the left pane, click
WebSvc. You should see the
LOANPAYM Web service listed and marked as
INSERVICE.
- On the list, click
Pipeline > JSONPIPE. You should see that the JSONPIPE pipeline is enabled.
- 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/LOANPAYM.
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.
- Close ESCWA.
