9. The options that you specified are displayed in the “Step 7: Summary of the Install New

Application wizard” panel, as shown in Figure 21-39. Verify that the options are correct,

and then click

Finish. A message is displayed that indicates first that the imsjavaRDS

application is being installed, and then that the installation was successful.

21.5.3 Step 3: Installing the metadata class for the sample application

We use IMS IVP application (DFSIVP37) for our sample Web application; therefore, we need

the metadata class from the DFSIVP37 PSB source and IVPDB2 DBD source. We already

discussed the sample metadata class creation in 21.3.1, “Example of using the DLIModel

utility” on page 422 with these PSB/DBD sources. In this section, we introduce how to set the

WebSphere Application Server for z/OS classpath to the location of your metadata classes.

Before adding the classpath, we compile the metadata source file and create the JAR file by

using the command shown in Example 21-23 on our UNIX System Services environment.

Example 21-23 Compile the metadata source and create the JAR file

JOUKO2 @ SC53:/u/jouko2>javac imsrds/*.java

JOUKO2 @ SC53:/u/jouko2/>jar -cvf imsrds.jar ./imsrds/*

added manifest

adding: imsrds/@dlictl(in = 601) (out= 274)(deflated 54%)

adding: imsrds/DFSIVP37DatabaseView.class(in = 1208) (out= 605)(deflated 49%)

adding: imsrds/DFSIVP37DatabaseView.java(in = 1279) (out= 517)(deflated 59%)

adding: imsrds/DFSIVP37DatabaseViewJavaReport.txt(in = 437) (out= 212)(deflated 51%)

adding: imsrds/META-INF/(in = 0) (out= 0)(stored 0%)

adding: imsrds/META-INF/MANIFEST.MF(in = 62) (out= 61)(deflated 1%)

adding: imsrds/imsrds.jar(in = 2495) (out= 2055)(deflated 17%)

One way to set the classpath is to add the metadata class to the IMS JDBC resource adapter

classpath by performing the following steps:

1. From the WebSphere Application Server for z/OS administrative console, click

Resources, and then click Resource Adapters. This displays a list of resource adapters,

as shown in Figure 21-40.

Figure 21-40 List of resource adapters

2. Click the name of the IMS JDBC resource adapter. A configuration panel opens, as shown

in Figure 21-41. In the Class path field, add your location of metadata class. In our case,

the location is /u/jouko2/imsrds/imsrds.jar.

Do not delete imsjava.jar. Click

OK.

3. Click Save. The Save page opens. Under Save to Master Configuration, click Save to

ensure that the changes have been made.

After completing this step, the configuration for then WebSphere Application Server for z/OS

side is completed. Then, you have to recycle the WebSphere Application Server for z/OS

region to reflect your new configurations.
