Major Description
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
