Unable to Execute Dynamic Query ln liferay 5.2.3

[vipin bardia, modificado hace 12 años.]

Java Code----
DynamicQuery dynamicQuery =DynamicQueryFactoryUtil.forClass(Custom.class);
dynamicQuery = dynamicQuery.add(PropertyFactoryUtil.forName("framework").eq(frmWork));

In above code Custom.class is our custom class and framework is our respective field.
As we add the filter to dynamicQuery It gives the below Error.

Error-------

Java.lang.ClassCastException: $Proxy304 cannot be cast to com.liferay.portal.dao.orm.hibernate.SessionImpl

Hi Apoorva,

First of all, i am really sorry for late reply.

We tried in that way mentioned in those link.
But still would not able to come out.

Now we are doing through simple jdbc.

Thanks for your reply.

Hello Vipin,
Dynamic query is implemented in exactly the very same fashion... Mine works...
And its almost impossible to point out the exact problem that you are facing...
There must be some minor issue...

Keep trying...

Thanks and regards

Hi Vipin,

i think in your case you must need to create new portlet and just build service again after putting your code in newly created portlet this will resolve your problem.
As the link suggested by apoorva is correct and we can definitely run the code properly.
