java ee - Liferay Service Builder failing -

i'm doing tests on liferay. this, i'm following mvc tutorial, , got stuck in services stuff.

i created simple entity testing purposes, "miclase":

public class miclase {     int id;     int num1;     string string1; } 

pretty simple, huh. well, after this, started service builder , created file this, overview pane:

<?xml version="1.0" encoding="utf-8"?> <!doctype service-builder public "-//liferay//dtd service builder 6.2.0//en" "http://www.liferay.com/dtd/liferay-service-builder_6_2_0.dtd"> <service-builder package-path="asd">     <author>hp</author>     <namespace>miservicio</namespace>      <entity name="miclase" local-service="true">         <column name="id" type="int"></column>         <column name="num1" type="int" primary="false"></column>         <column name="string1" type="string"></column>           <!-- pk fields -->          <column name="miclaseid" type="long" primary="true"></column>          <!-- group instance -->          <column name="groupid" type="long"></column>          <!-- audit fields -->          <column name="companyid" type="long"></column>         <column name="userid" type="long"></column>         <column name="username" type="string"></column>         <column name="createdate" type="date"></column>         <column name="modifieddate" type="date"></column>         <finder name="groupid" return-type="collection">             <finder-column name="groupid"></finder-column>         </finder>     </entity> </service-builder> 

everything showed without errors in "overview" pane, clicked "build service" button, created lot of source code:

but... after previous output, following build fails:

did wrong here?

i don't know if "id" column allowed on liferay or 1 of reserved identifiers columns on service builder.

could try id_ instead of id column?

hope helps.

edit: i've seen you're using java 8. please test java 7 , tell us.
