SERVICE BULIDER

-


I have referred the some of the documents and materials about service Bulider.

Here is some of the statments. 

ServiceBuilder will create models, services, and service persistence first in the folder ext/ext-service, which will form ext-service.jar and it goes to the $CATALINA_HOME/lib/ext in Ext deployment. Here are the packages of the services for the portlet, Reports:
com.ext.portlet.reports.model
com.ext.portlet.reports.service
com.ext.portlet.reports.service.persistence
Then ServiceBuilder will create implementations of models, services and service persistence in the folder, ext/ext-impl. This will form ext-impl.jar and it goes to $CATALINA_HOME/webapps/ROOT/WEB-INF/lib in Ext deployment. Here are packages of the implementations of the services for the portlet, Reports:
com.ext.portlet.reports.model.impl
com.ext.portlet.reports.service.base
com.ext.portlet.reports.service.http
com.ext.portlet.reports.service.impl
com.ext.portlet.reports.service.persistence



Service Builder divides the source it generates into two layers:

        Interface layer and an implementation layer.

The interface layer gets generated in the aforementioned service folder. You will never change anything in the interface layer manually; Service Builder always generates the code that is found there.

 The implementation layer gets generated in your src folder and is initially just skeleton code which allows you to implement the functionality you need.

Viewing the SQL Query in liferay : debugging the SQL Query in Hibernate

-
Sometimes we have to know SQL query hiting in DB to retrieve the list. Suppose When we are writing the DynamicQuery , Some times we have to know SQL query it is generating to hit DB. So generally it is useful when we are debugging the Query it is generated. In hibernate we used the write the property in XML file as hibernate.show.sql to view the query. In Liferay also we can also set the below property to true in the portal-ext.properties to view the SQL query at the console. hibernate.show_sql=true. By adding the above property it will just reterive the parameters. What if we want to display the parameters. Add the below properties in log4j.properties it will display the paramters also. # logs the SQL statements #log4j.logger.org.hibernate.SQL=debug # Logs the JDBC parameters passed to a query #log4j.logger.org.hibernate.type=trace In Liferay log4j is located in the below location tomcat-7.0.42\webapps\ROOT\WEB-INF\classes Also we want t...

Executing the BackGround Task

In Liferay we can exceute the background task asynchrously. The Background Task framework allows the developers to create and manage any kind of tasks that need to be run in a separated thread without the need of knowing anything about JAVA threading or concurrency Here the code ThemeDisplay themeDisplay = (ThemeDisplay) request.getAttribute(WebKeys.THEME_DISPLAY); Map taskContextMap = null; String taskName = null; String servletContextNames [] = new String[1] ; Portlet portlet = PortletLocalServiceUtil.getPortletById(request.getAttribute(WebKeys.PORTLET_ID).toString()); servletContextNames[0] = portlet.getContextName(); try { BackgroundTaskLocalServiceUtil.addBackgroundTask(themeDisplay.getUserId(), themeDisplay.getScopeGroupId(), taskName, servletContextNames,TestBackgroundTaskExecutor.class, taskContextMap,new ServiceContext()); } catch (PortalException e) { e.printStackTrace(); } catch (SystemException e) { e.printStackTrace(); } ...
