Liferay Error : Unable to find model in Dynamic Query

We already know how to write dynamic query in Liferay. If we create Dynamic Query object in same portlet in which our service are then we can use :-

	DynamicQuery query = DynamicQueryFactoryUtil.forClass(Employee.class, "emp",PortletClassLoaderUtil.getClassLoader());

But if we use this code in another portlet ie Services in one portlet and our portlet is different then we get error on our console:-

[DynamicQueryFactoryImpl:96] Unable find model com.liferay.sample.model.impl.EmployeeImpl

java.lang.ClassNotFoundException: com.liferay.sample.model.impl.EmployeeImpl

Solution:-

In this case you can create Dynamic Query Object as:-

	ClassLoader classLoader = (ClassLoader)PortletBeanLocatorUtil.locate(ClpSerializer.getServletContextName(),"portletClassLoader");
	DynamicQuery dynamicQuery = DynamicQueryFactoryUtil.forClass(Employee.class, "emp", classLoader);

Explanation:-
The only difference is the way how we use the Class Loader.

Hope this will Help....
