getServiceNull() is Null -Service Builder

[6年前 に Ola Torres によって更新されました。]

Hi,

We have this module created through Service Builder.

<service-builder package-path="com.sample.mqs">
	<namespace>SAMPLEHISTORY</namespace>
	<!--<entity data-source="sampleDataSource" local-service="true" name="Foo" remote-service="false" session-factory="sampleSessionFactory" table="foo" tx-manager="sampleTransactionManager uuid="true"">-->
	<entity local-service="true" name="SampleHistory" remote-service="true" uuid="true" table="sampleHistory" cache-enabled="false">
        <column name="search_id" type="long" primary="true"></column>
        <column name="historyID" type="String"></column>
        <column name="userid" type="String"></column>
        <column name="groupid" type="long"></column>
        <column name="createdDate" type="Date"></column>

		<!-- References -->
        <order by="desc">
            <order-column name="createdDate" order-by="desc"></order-column>
        </order>
        <finder name="historyID" return-type="Collection" db-index="true">
            <finder-column name="userid"></finder-column>
            <finder-column name="historyID"></finder-column>
            <finder-column name="groupid"></finder-column>
        </finder>
        <finder name="GroupId" return-type="Collection">
            <finder-column name="userid"></finder-column>
            <finder-column name="groupid"></finder-column>
        </finder>

		<reference entity="AssetEntry" package-path="com.liferay.portlet.asset" />
		<reference entity="AssetTag" package-path="com.liferay.portlet.asset" />
	</entity>
</service-builder>

Then after months it was refactored into another name of package: "com.history.samples.mqs"
1. I ran the service builder task.
2. Added a custom function in -service module, ran the service builder task again
3. Deployed in tomcat locally (working fine)

I deployed the same jar files in different tomcat, null pointer appears in "getService() in the return of the method below

public static com.history.samples.mqs.SampleHistory getSampleHistory(long search_id) throws com.liferay.portal.kernel.exception.PortalException {
return getService().getSampleHistory(search_id);
}

Hope some one can give me some light. I do not have any idea why it doesn't work in different environment (with the same set up as mine)
but doesn't work in my local.
