My class looks like:
public class NpaResultsTableFunction extends VTITemplate implements
RestrictedVTI {
public static NpaResultsTableFunction read() throws SQLException {
return new NpaResultsTableFunction();
}
public NpaResultsTableFunction() throws SQLException {
conn = DriverManager.getConnection("jdbc:default:connection");
}
...
}
I have defined the function using the following where "csem-pcs-derby-jar" is
the location of the JAR file containing this table function:
CALL SQLJ.INSTALL_JAR('${csem-pcs-derby-jar}',
'PCS_V1.pcsderby', 0);
SET SCHEMA PCS_V1;

All of this is okay and before I tried to make this a restricted table
function, worked correctly. All the above loads into the database correct
right now, but when I execute:
select * from table (PCS_V1.NPARESULTS_TABLE()) s
I get:
Error: The class 'com.canoga.derby.fcn.NpaResultsTableFunction' does not exist
or is inaccessible. This can happen if the class is not public.
SQLState: 42X51
ErrorCode: -1
Error: Java exception: 'com.canoga.derby.fcn.NpaResultsTableFunction :
org/apache/derby/vti/RestrictedVTI: java.lang.ClassNotFoundException'.
SQLState: XJ001
ErrorCode: 99999
It appears that the class "org.apache.derby.vti.RestrictedVTI" cannot be found.
Derby is 10.8.1.2 and is started using the startNetworkControlServer script.
Do I need to andy anything else via the "derby.database.classpath" for it to
find "org.apache.derby.vti.RestrictedVTI"?
Any help will be greatly appreciated.
