[tcljava-user] Class not found after successful class import.

[Patrick F. <pfi...@hb...>]

The following code is executed inside a proc.  The "EmbeddedDriver" class 
is imported successfully but attempts to instantiate the object generate a class not 
found error. 


# import required classes 
   java::import org.apache.derby.jdbc.EmbeddedDriver
   java::import org.apache.derby.drda.NetworkServerControl
   java::import org.apache.derby.jdbc.ClientDriver
   java::import java.sql.Connection
   java::import java.sql.DriverManager
   java::import java.sql.ResultSet
   java::import java.sql.SQLWarning
   java::import java.sql.Statement
   java::import java.sql.ResultSetMetaData 

   puts "\nimported classes are:\n"
 
   foreach i [java::import] {
 
      puts [ format "%-5s %-50s" " " $i ] 

   }

This generates ==>

imported classes are:

      org.apache.derby.drda.NetworkServerControl
      java.sql.DriverManager
      org.apache.derby.jdbc.ClientDriver
      java.sql.ResultSetMetaData
      java.sql.Statement
      org.apache.derby.jdbc.EmbeddedDriver
      java.sql.ResultSet
      java.sql.Connection
      java.sql.SQLWarning
