Hi I am new to TEIID , and trying to deploy UDF  and corresponding JAR at run time .

It is showing following exception:-

===============================


I have crated a dynamic VDB and  define UDF details as follows 

<?xml version="1.0" encoding="utf-8"?>
<vdb name="DDS_TEST_VDB" version="1">
	<model  name="modelsource" type='VIRTUAL' >
         <property name ="lib" value ="com.my.app"></property>
		<metadata type="DDL">
			<![CDATA[
			create virtual function getDouble(key Long) returns Double
			options (
				java_class 'com.my.app.Demo',
				java_method 'getValue'
			);
			]]>
		</metadata>
	</model>
</vdb>

 And I have deployed my jar file and module.xml in following path,
\teiid-8.12.2-server\teiid-8.12.2\modules\com\my\app\main\

module.xml :  

<?xml version="1.0" encoding="UTF-8"?>
 
<module xmlns="urn:jboss:module:1.1" name="com.my.app">
     
    <resources>
        <resource-root path="myapp.jar"/>
        <!-- Insert resources here -->
    </resources>

    <dependencies>
    </dependencies>
</module>

Thanks,
Durga
