Use of PortalClassInvoker in Liferay-Portlet...

Some times we need to use portal-impl classes functionality,but we can't access that in our custom portlet. Hence,we require to PortalClassInvoker class.

for example : we need to access PortalLDAPUtil.getLdapServerId()(method for get LDAP ServerId) in our costum portlet and it's there in portal-impl ,so access is the issue. For that , we use PortalClassInvoker.invoke() (This method have many forms) with MethodKey.

Following are steps to use PortalClassInvoker.invoke() method to access utility of portal-impl class PortalLDAPUtil.

1) Initialize MethodKey object.
   
    Syntax : MethodKey portalLDAPUtilMethodKey = new MethodKey("classNameWithPackagePath", "methodName",argClassType1,argClassType2......);
   
    Example : MethodKey portalLDAPUtilMethodKey = new MethodKey("com.liferay.portal.security.ldap.PortalLDAPUtil", "getLdapServerId",Long.class,String.class);
   
2) Use PortalClassInvoker.invoke() to access portal-impl classes using MethodKey.
    Syntax : PortalClassInvoker.invoke(newInstance, methodKey, argumentList);
   
    Example : Long ldapServerId = (Long) PortalClassInvoker.invoke(false, portalLDAPUtilMethodKey, new Object[] {Long.valueOf(themeDisplay.getCompanyId()),screenName});
here screenName is ldap user screenName. i.e. “ketan.savaliya”.

Deployment/ReDeployment ext in liferay

I assume that you have WAR file ready for deployment and name of ext is abc-ext.war.

1          1.       First of all, shutdown your tomcat if it's already running and delete your work and temp folder.

2          2.       Now go to \tomcat\lib\ext folder , and remove ext-abc-ext-service.jar.

3          3.       Go inside webapps, and remove the abc-ext.

4          4.       Go inside webapps\ROOT\WEB-INF and remove

·         liferay-display-ext.xml

·         ext-abc-ext.xml

·         liferay-portlet-ext.xml

·         portlet-ext.xml,

   5.     Go inside webapps\ROOT\WEB-INF\lib and delete

·         ext-abc-ext-impl.jar,

·         ext-abc-ext-util-bridges.jar,

·         ext-abc-ext-util-java.jar

·         ext-abc-ext-util-taglib.jar.

    Start the tomcat.

    Put WAR file inside hot deploy folder and wait till it expends and give message to reboot your server.

    Restart tomcat and its done.
