Liferay Category Import Export Apps on Liferay Market Place

Here i am sharing one more my work experience to liferay community.

I hope this may help to many liferay developer during development. it's about import/export functionality of Category.

Many time we need create long list of categories. Once we create all categories structure to particular community or organization then we want to copy whole structure to another community or another server. Currently we don't have any option doing this easily within few clicks. Again we need rework all categories entry.

So, here i come up with solution. I created App for that which is use to import/export category list from or to liferay community or organization.

Here you can find my liferay apps from Liferay market place Liferay Category Import-Export App

Web content data display in custom-portlet

Many more time during development we need display liferay web-content in our custom-portlet.
Liferay taglib already give tag to display web-content data.

Here is syntax for "<liferay-ui:journal-article/>"

<<liferay-ui:journal-article showTitle="true/false" articleId="longArticleId" groupId="longGroupId" />


Let take an example...

<<liferay-ui:journal-article showTitle="false" articleId="<%= journalArticleId%>"
groupId="<%= themeDisplay.getScopeGroupId() %>" />

here journalArticleId is long var which is articelId of web-content

Servidce/Util classes access in template (.vm) file in Liferay

Hi Developers,

Many times you need to access services/util class in template. 

Below is some importance hits for the same.

=> Access services using findService method in Velocity(vm)

#set ($userLocalService= $serviceLocator.findService("com.liferay.portal.service.UserLocalService"))

=>Access util class using  findUtil Method for inbuilt Util of Liferay

#set ($journalContentUtil = $utiLocator.findUtil("com.liferay.portlet.journalcontent.util.JournalContentUtil"))

=> some times you also need to access util class which is not have access in template file like StorageEngineUtil. for that you can use below approch..

#set ($util = $portal.getClass().forName("com.liferay.portlet.dynamicdatamapping.storage.StorageEngineUtil").newInstance()) 


HTH.. :))
