Chapter 10 Creating Application Clients

Configuring application client properties

You can configure an application client's properties in Jaguar Manager. If you have created an Enterprise archive (EAR) file using another tool and imported it into EAServer, most properties are automatically set during the import process.

Displaying the Application Client Properties dialog

To set the properties described in this section, first open the Application Client Properties dialog.

Expand the Clients folder, then highlight the icon that represents your application client.
Choose File | Application Client Properties.

General properties

Enter the application client's general properties:

Description An optional text description of the application client.
Main Class The main Java class of the application client in dot notation; for example, com.sybase.appclient.Myclient .

EJB references

Add references for the EJBs that the application client accesses in its code. For example, add the EJB reference ejb/acctBean in Jaguar Manager and use java:comp/env/ejb/acctBean in your application client code.

"EJB references" describes how to add or configure EJB references.

Resource references

Resource references are used to obtain connector and database connections, and to access JMS connection factories, JavaMail sessions, and URL links.

"Resource references" describes how to add and configure resource references.

Resource environment references

Resource environment references are logical names applied to objects administered by EAServer, such as JMS message queues and topics.

"Resource environment references" describes how to add and configure resource environment references.

Environment properties

Environment properties allow you to specify global read-only data for use by the application client.

Application clients must use JNDI to retrieve environment properties, using the prefix java:comp/env in JNDI lookups.

The deployment descriptor catalogs the environment properties used by the application client, as well as each property's Java datatype and default value.

"Environment properties" describes how to add and configure environment properties.

Java classes

The Java Classes tab allows you to specify classes that must be included in the Application Client's run-time JAR file. "Configuring the custom class list" describes how to configure this setting.

JAXP properties

The settings on the JAXP tab configure the JAXP, DOM, and XSLT parser implementations used in the application client. See Chapter 27, "Configuring Java XML Parser Support"for more information on these properties.

Application client files

The Files tab lists all the files in the application client, which are copied to %JAGUAR%\ Repository\<Application_Name>\<Client_Name> when you deploy the application EAR file. When you export the client application, the files listed on this tab, plus the EJB stubs for the application are added to the export JAR file, which you deploy on a client machine to run the application.
