Modifying the JClient Login Dialog for JDBC

This topic describes how to modify the generated JClient login dialog to work with a JDBC connection instead of OracleAS JAAS Provider.

To modify the generated JClient login dialog for JDBC connections:

Add the login dialog to your JClient project using the Create JClient Form wizard or the Create JClient Empty Form wizard.
Double-click the file JCLoginDialog.java in your JClient project. The file opens in the Code Editor.

Comment out the following code so it looks like this:


/*

	String securityEnforceStr = ((String)((Hashtable)connEnvironment).get(PropertyMetadata.ENV_SECURITY_ENFORCE .pName)); 

    if (securityEnforceStr == null || (securityEnforceStr != null && PropertyConstants.SECURITY_ENFORCE_NONE.equals(securityEnforceStr))) 

    { 

       return null; 

    }

*/

Press Ctrl+F to display the Find dialog in the Code Editor and perform this search and replace operation:

Change JboContext.SECURITY_PRINCIPAL to Configuration.DB_USERNAME_PROPERTY.
Display the Find dialog again and perform another search and replace operation:

Change JboContext.SECURITY_CREDENTIALS to Configuration.DB_PASSWORD_PROPERTY.

Note: These changes appear twice within the file: once where reading from the hash table and once when setting user name and password from the fields in the login dialog.
Save the changes to JCLoginDialog.java in your JClient project.
If you deployed the password when you created your Business Components project (the default), you need to change these settings. Locate the bc4j.xcfg file in your Business Components project and open it in the XML Editor.
With the bc4j.xcfg file open, remove these entries and save the file:

<ENTRY name="DeployPassword" value="true"/>

and

<ENTRY name="password" value="mypassword"/>

You are now ready to run your JClient application. If you have a JDBC connection that the bc4j.xcfg file names, the application will invoke the dialog automatically.

Note, if your bc4j.xcfg file contains the user password, the dialog will display more than one time. To avoid this, be sure to remove the lines as describe in the above procedure.
