OSM DataInstance JDBC Adapter: Invalid SQL issue....

Question

Hi,
We are facing one issue while using the database adapter as DataInstance Behavior.
Here are the scripts we used for the highlighted parameters:
oms:datasource as XPATH: 'mslv/oms/oms1/internal/jdbc/DataSource'
oms:sql as XQUERY:
<instance name="OSM" xsi:type="externalInstanceType">
<adapter>com.mslv.oms.view.rule.adapter.DatabaseAdapter</adapter>
<parameter  name="oms:dataSource"> 'mslv/oms/oms1/internal/jdbc/DataSource'</parameter>
<parameter name="oms:sql">
"SELECT P.NODE_VALUE_TEXT FROM ORDERMGMT_OSMINSTALL.OM_ORDER_INSTANCE  P
JOIN ORDERMGMT_OSMINSTALL.OM_ORDER_DATA_DICTIONARY PP
ON P.DATA_DICTIONARY_ID=PP.DATA_DICTIONARY_ID
where  PP.DATA_DICTIONARY_MNEMONIC='site_id' "
</parameter>
</instance>
The following error logged in Logfile:
<Feb 18, 2014 5:30:16 AM IST> <Error> <oms> <BEA-000000> <impl.j: failed to invoke adapter for externalInstanceType: name[DataInstance] class[com.mslv.oms.view.rule.adapter.DatabaseAdapter]

Can you pls suggest the remedy for this issue in the SQL? The same SQL runs well in TOAD and also shows the selected rows.
Thanks in advance..

Thanks Viktor.
I have not tried the Webservice option due to the processing time to retrieve all the orders and then this particular field.
But I have tried both lookup as well as calculate behaviors.
Now I am neither getting any exception in the log nor the update reflects in my Webclient task view. Have your view gets updated with the calculate behavior?
I am using OSM SDK version [7.0.3.745].
My task_view.xml shows as following with lookup:
<viewNode element="b_end_site_id">
    <editable>true</editable>  <minOccurs>1</minOccurs>
    <maxOccurs>1</maxOccurs>
        <viewRule xsi:type="dataInstanceRuleType">
            <description>DataInstance</description>
            <instance xsi:type="externalInstanceType"
                name="DataInstance">
                <adapter>com.mslv.oms.view.rule.adapter.DatabaseAdapter</adapter>
                <parameter name="oms:dataSource">&#039;mslv/oms/oms1/internal/jdbc/DataSource&#039;</parameter>
                <parameter name="oms:sql">&#039;SELECT P.NODE_VALUE_TEXT FROM ORDERMGMT_OSMINSTALL.OM_ORDER_INSTANCE  P
JOIN ORDERMGMT_OSMINSTALL.OM_ORDER_DATA_DICTIONARY PP
ON P.DATA_DICTIONARY_ID=PP.DATA_DICTIONARY_ID
where  PP.DATA_DICTIONARY_MNEMONIC=?&#039;
</parameter>
                <parameter name="in:1">&#039;site_id&#039;</parameter>
                <cache>
                    <scope>SYSTEM</scope>
                    <timeout>15000</timeout>
                    <maxSize>50</maxSize>
                </cache>
            </instance>
        </viewRule>
        <viewRule xsi:type="lookupRuleType">
            <annotation>
                <documentation>This behavior retrieves the inline XML defined for the data instance behavior and displays it  as a lookup field, which is the same as a dropdown list field,  in the Web client</documentation>
            </annotation>
            <description>LookUp</description>
            <itemset>
                <nodeset>instance(&#039;DataInstance&#039;)/rowSet/row/NODE_VALUE_TEXT</nodeset>
                <value name="Value" openSelectionSeverity="CRITICAL" sortOrder="0" sortDirection="ascending" hidden="false" position="0">
                    <node>text()</node>
                </value>
            </itemset>
        </viewRule>
</viewNode>
With Calculate, it shows following:
<viewNode element="a_end_site_id">
    <editable>true</editable>  <minOccurs>1</minOccurs>
    <maxOccurs>1</maxOccurs>
        <viewRule xsi:type="dataInstanceRuleType">
            <description>DataInstance</description>
            <instance xsi:type="externalInstanceType"
                name="DataInstance">
                <adapter>com.mslv.oms.view.rule.adapter.DatabaseAdapter</adapter>
                <parameter name="oms:dataSource">&#039;mslv/oms/oms1/internal/jdbc/DataSource&#039;</parameter>
                <parameter name="oms:sql">&#039;SELECT P.NODE_VALUE_TEXT FROM ORDERMGMT_OSMINSTALL.OM_ORDER_INSTANCE  P
JOIN ORDERMGMT_OSMINSTALL.OM_ORDER_DATA_DICTIONARY PP
ON P.DATA_DICTIONARY_ID=PP.DATA_DICTIONARY_ID
where  PP.DATA_DICTIONARY_MNEMONIC=?&#039; </parameter>
                <parameter name="in:1">&#039;site_id&#039;</parameter>
                <cache>
                    <scope>SYSTEM</scope>
                    <timeout>15000</timeout>
                    <maxSize>50</maxSize>
                </cache>
            </instance>
        </viewRule>
        <viewRule xsi:type="calculateRuleType">
            <description>Calculation</description>
            <calculation>instance(&#039;DataInstance&#039;)/rowSet/row/NODE_VALUE_TEXT/text()</calculation>
        </viewRule>
</viewNode>
