How use custom Overrided Portal Service by hook in another custom portlet

[omid ahmadi, módosítva 9 év-val korábban]

Hi friends,
i'm using liferay 6.1 CE GA2 .
While i want to use JournalStructureFinderUtil method in my portlet i faced this error:

org.hibernateException: No Hibernate Session bound to thread , and configuration dose not allowed creation of no-transactional one 

To solve this poroblem i decided to override JournalStructureLocalService by hook and add a new method to call this method :

JournalStructureFinderUtil.findByKeywords(companyId,
				groupIds,
				keywords, 
				0, end, obc);

My custom class code is here:

package  com.liferay.journalStructure.finderUtil;

import java.util.List;

import com.liferay.portal.kernel.exception.PortalException;
import com.liferay.portal.kernel.exception.SystemException;
/*import com.liferay.portal.model.User;
import com.liferay.portlet.;
import com.liferay.portal.service.UserLocalServiceWrapper;*/

import com.liferay.portal.kernel.util.OrderByComparator;
import com.liferay.portlet.journal.model.JournalStructure;
import com.liferay.portlet.journal.service.JournalArticleImageLocalService;
import com.liferay.portlet.journal.service.JournalStructureLocalService;
import com.liferay.portlet.journal.service.JournalStructureLocalServiceWrapper;
import com.liferay.portlet.journal.service.persistence.JournalStructureFinderUtil;


public class MyJournalStructureFinderUtil extends JournalStructureLocalServiceWrapper
{
	public MyJournalStructureFinderUtil(
			JournalStructureLocalService journalStructureLocalService) {
		super(journalStructureLocalService);
		// TODO Auto-generated constructor stub
	}

	public List<journalstructure> findMyjournalStructuresByKeyword(
			long companyId,
			String keywords, 
			long[] groupIds, 
			int start, 
			int end , 
			OrderByComparator obc) throws SystemException
	{
		//long companyId=10154;
		
	return	JournalStructureFinderUtil.findByKeywords(companyId,
				groupIds,
				keywords, 
				0, end, obc);
	}
	
	
	
	
}</journalstructure>

And finally , now my problem is How use custom Overrided Portal Service method by hook in another custom portlet???

Hi Omid,

Sometime back I had come across the same issue. After fixing the issue, I wrote a blog on the fix at the link :

You can check if the solution works for you.

Hi Omid,

I imagine that you could solve this the same way you would to share service builder (service) libraries among multiple plugins. Move the inheritted class to a separate jar and place it in the global libraries (e.g. TOMCAT_HOME/lib/ext) so that it is accessible by all plugins. You can still use your hook, it just means that it will reference classes from the global classloader scope rather than it's own classloader.
