Service Builder Error

[Shravan Babu, modificado hace 12 años.]

Hi,

I'm using Liferay 6.1 tomcat. Service builder is giving me errors while building.
I'm not able to figure out what the problem is. The service.xml is looks perfectly fine. but gives out errors while running the service builder.

My service.xml

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE service-builder PUBLIC "-//Liferay//DTD Service Builder 6.0.0//EN" "http://www.liferay.com/dtd/liferay-service-builder_6_0_0.dtd">
<service-builder package-path="com.attendance.details">
<author>shravan</author>
<namespace>Att</namespace>
<entity name="Attendance">
<column name="recordId" type="long" primary="true"></column>
<column name="createDate" type="Date"></column>
<column name="groupId" type="long"></column>
<column name="companyId" type="long"></column>
<column name="subject" type="String"></column>
<column name="teacherId" type="long"></column>
<column name="absenteeId" type="Collection"></column>
<column name="modifiedDate" type="Date"></column>
<order by="asc">
<order-column name="createDate"></order-column>
</order>
<finder name="ClassDetails" return-type="Collection">
<finder-column name="groupId"></finder-column>
<finder-column name="companyId"></finder-column>
</finder>
<finder name="ClassDate" return-type="Collection">
<finder-column name="groupId"></finder-column>
<finder-column name="companyId"></finder-column>
<finder-column name="createDate"></finder-column>
</finder>
<reference entity="User" package-path="com.liferay.portal"></reference>
</entity>
</service-builder>

I'm getting the following error while running the service builder

Hi Shravan,

Have you solved your issue yet? There is no type "Collection" for columns.

Hi Amos,

Thanks for your reply.
It worked after removing the type 'Collection'

Shravan
