TR: [opencms-dev] Implement I_CmsEventListener

[Apostoly Guillaume]

Hi Ian,

To make your listener listen you have to : 
- implement it
- update registry.xml as below (add the launcher5 by example, line)
- restart your webapp.

 <launchers>
            <launcher1>com.opencms.flex.CmsXmlTemplateLoader</launcher1>
            <launcher2>com.opencms.flex.CmsDumpLoader</launcher2>
            <launcher3>com.opencms.launcher.CmsLinkLauncher</launcher3>
            <launcher4>com.opencms.flex.CmsJspLoader</launcher4>
            <launcher5>com.put.your.listerner.class.HERE!</launc
her5>
        </launchers>

Hope this helps,

ps: I see that someone gave the programmatic way to do this, mine is the
config way. Have fun :)

Objet: [opencms-dev] Implement I_CmsEventListener


Listed below is the javadoc for I_CmsEventListener.
I am very interested in implementing this interface
(by a concrete class).  My biggest question is how do
I configure opencms to pick up my new listener class ?
 Is there a config file or some other way ?

/**
 * Implement this interface in case your class has to
react 
 * to CmsEvents that are thrown by system.<p>
 * 
 * In order to recieve system events, your class must
register with 
 * the OpenCms event mechanism. This can be done in
the constructor of a class
 * like this:
 * <pre>
 *
com.opencms.core.A_OpenCms.addCmsEventListener(this);
 * </pre>
 * 
 * A typical implementation might look like this:
 * <pre>
 * public void cmsEvent(com.opencms.flex.CmsEvent
event) {
 *     switch (event.getType()) {
 *         case
com.opencms.flex.I_CmsEventListener.EVENT_PUBLISH_PROJECT:
 *         case
com.opencms.flex.I_CmsEventListener.EVENT_CLEAR_CACHES:
 *             // do something
 *             break;
 *         case
com.opencms.flex.I_CmsEventListener.EVENT_LOGIN_USER:
 *            // do something else
 *             break;
 *         }
 * }
 * </pre>
