Dynamic Query with PortletClassLoader using PortletBeanLocatorUtil


Hello,

Recently I faced some issue with dynamic query. Even though my service layer and Portlet are in the same war  I got class not found exception for the model class.

Now there are two scenarios one is if you want to debug the Javascript code you have included in the Portlet View JSP, and the other one is when you load a page and you wan to see all the individual JS and CSS files getting loaded instead of a single mindifed bundle.

PermissionChecker permissionChecker =PermissionThreadLocal. getPermissionChecker (); boolean status = PortletPermissionUtil. contains ( permissionChecker , “your portlet root id”, “your permission” ); You can find the portlet root id from Liferay page. Goto the page where the portlet resides and click on Settings icon- > Look and Feel -> and goto Advanced Styling tab. There you can see the p...
