Thank you Steven !!
I am not using teiid designer . only using dynamic vdb to create UDF.
As you specified I create a TESTUDF.vdb, zip file with following structure,
/META-INF
vdb.xml
/lib
testudf.jar
The content of vdb.xml is as follows, Here I have removed the module reference property,
<?xml version="1.0" encoding="utf-8"?>
<vdb name="DDS_TEST_VDB" version="1">
<model name="modelsource" type='VIRTUAL' >
<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>
But now same error is coming ,
1:01:20,571 INFO [org.teiid.RUNTIME] (teiid-async-threads - 5) TEIID50030 VDB UDFVDB.1
model "modelsource" metadata loaded. End Time: 2/10/16 11:01 AM
11:01:20,581 ERROR [stderr] (teiid-async-threads - 5) Exception in thread
"teiid-async-threads - 5" org.teiid.metadata.MetadataException: TEIID30387 Could
not load UDF "doADD", since its invocation class "com.my.app.Demo"
could not be found.
11:01:20,591 ERROR [stderr] (teiid-async-threads - 5) at

2- Is there any way to specify the module slot name in VDB property file, so that it will
access corresponding version module ?
Thanks,
Durga

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
