4.4.4 Setting a plugin for database connection processing

To set database connection processing in a plugin, you need to edit the two files (web.xml and cosminexus.xml) to add resource adapter information. The following shows the storage location and editing contents of each file.

Important: To edit web.xml and cosminexus.xml, use the editor started by selecting Run as administrator.

Organization of this subsection

(1) Editing web.xml
(2) Editing cosminexus.xml

(1) Editing web.xml

Add the resource definition to the web.xml file of the User Plugin. The web.xml file is stored in:

Navigation-Platform-for-Developers-installation-directory\pluginSDK\plugin\plugin-ID\WEB-INF\web.xml

The following shows a coding example when the resource reference name is jdbc/TP_Connector_for_HiRDB_Type4:

<resource-ref>
  <res-ref-name>jdbc/TP_Connector_for_HiRDB_Type4</res-ref-name>
  <res-type>javax.sql.DataSource</res-type>
  <res-auth>Container</res-auth>
</resource-ref>

Add the above lines to immediately before </web-app> at the end of the web.xml file.

Navigation-Platform-for-Developers-installation-directory\pluginSDK\plugin\plugin-ID\dd\META-INF\cosminexus.xml

The following shows a coding example when the resource reference name is jdbc/TP_Connector_for_HiRDB_Type4 and the resource adapter display name is TP_Connector_for_HiRDB_Type4:

<resource-ref>
  <res-ref-name>jdbc/TP_Connector_for_HiRDB_Type4</res-ref-name>
  <linked-to>TP_Connector_for_HiRDB_Type4</linked-to>
</resource-ref>

Add the above lines to immediately before </war> at the end of the cosminexus.xml file.
