Please tell me step so that i can do this task.

Thanks a lot

follow this steps :

1) Make TestData table dump in liferay DB
2) create service.xml with te column name you have in your table
and put service.xml in your cutome portlet location (test-portlet/docroot/WEB-INF)

<!--?xml version="1.0"?-->


<service-builder package-path="com.liferay.portlet.journal">
	<namespace>test</namespace>
	<entity name="TestData" uuid="true" local-service="true" remote-service="true">
		<!-- PK fields -->
		<column name="id" type="long" primary="true" />
		<column name="fname" type="String" />
		<column name="lname" type="String" />
	</entity>

</service-builder>

3) Now build the service using ant build-service command from portlet
4) Now it will generate some classes and you can check that TestDataLocalServiceImpl class has been generated or not .
5) Now define your method in that class to get data all data even you can get data by promary key and other parameter as well.

package com.liferay.portlet.journal.service.impl;

import com.liferay.portal.kernel.exception.SystemException;
import com.liferay.portlet.journal.model.TestData;
import com.liferay.portlet.journal.service.base.TestDataLocalServiceBaseImpl;
import com.liferay.portlet.journal.service.persistence.TestDataUtil;

public class TestDataLocalServiceImpl extends TestDataLocalServiceBaseImpl {
	public java.util.List<testdata> getData() throws SystemException{
		java.util.List<testdata> dataList = TestDataUtil.findAll();
		return dataList;		
	}
}
</testdata></testdata>

Now in jsp you can write to get all data :

<%=TestDataLocalServiceUtil.getData()%>

Thanks Jignesh,

I followed the same step but getting the error.

An error occurred at line: 372 in the jsp file: /html/portlet/document_library/edit_file_entry.jsp

TestDataLocalServiceUtil cannot be resolved

Please look into this and suggest me what i have to do?

Thanks
Amit

Please import below line in jsp:

<%@page import="com.liferay.portlet.journal.service.TestDataLocalServiceUtil"%>

Hi Jignesh,
I have already imported the page
--------------------------------------com.liferay.test.cp.service.TestDataLocalServiceUtil ( i am using a hook for make changes in edit_file_entry.jsp)
now i am getting the error
Only a type can be imported. com.liferay.test.cp.service.TestDataLocalServiceUtil resolves to a package

Please u have any idea about it.

Thanks
Amit

provide your table entity here with all columns so that i can give you exact code here .
Here whatever code i putted is working in my local so you would be following something different way i think.

Hi Jignesh,
I have a table---- Siteinfo which have two coloumn(Siteid,sitedescription).
Siteid----sitedescription
123----->heritage site
345----->iucn information

I have requirement on uploading data each documents have a site id associated with it.

so we have made some changing in edit _file_entry.jsp for this.

Please help me .

Thanks
Amit

Amit,
IF your entity name is Siteino then you may have class name SiteInfoLocalServiceUtil instead of TestDataLocalServiceUti.
If your service builder has generated all classes proper then you can easily find with your eclipse IDE.
SO follow steps properly which i mentioned in my previous post .

Hi Amit,

If you have created service.xml in some test-portlet under Plugin-SDK then your Util classes by default will not be accessible to your JSP in Hook as those are in different class loader.

If that is the path you want to follow, then you will have to copy your service jar generated by service-builder & paste in to the Global lib directory of your application server ([tomcat]/lib/ext) if you are using Tomcat , remove it from your portlet's lib directory & restart the server.

Hi,
Expando is also a good solution for you problem.

More on expando : Expando Usage

[Jignesh Vachhani, geändert vor 11 Jahren.]

Pranay, I think Amit has data already in table and he wants to reuse that table data if i am not wrong.
So in that case use of Expando could not be suitable solution as per my knowledge.

You can try as (for liferay 6.1) :
FileEntry fileEntry = DLAppLocalServiceUtil.addFileEntry(userId, repositoryId, folderId, sourceFileName, mimeType, title, description, changeLog, bytes, serviceContext);
fileEntry.getExpandoBridge().setAttributeDefault("custon-aatibute", defaultValue);


defaultValue can be given by DB.
