Hey Eric,

Don't use the "package org.enhydra.instantdb;", just make your own package, you
get the error message
becoz of the import line:"import org.enhydra.instantdb.*;" use this instead :"
import org.enhydra.instantdb.jdbc.*;".

This should make your example work.





Regards

Martin

I'm new to InstantDb and I'm just trying to build the database without any of
the tables.

I have jdk1.3 and the latest InstantDB
running on Win 2000.

My paths:
c:\java\jar
- has all the idb.jar files

Here is my code:

package org.enhydra.instantdb;

import org.enhydra.instantdb.*;
import java.sql.*;

public class CreateDatabase
{

     public static CreateDatabase objCreateDatabase;

     public CreateDatabase()
     {
    Connection conn;
          try
          {

               Class.forName( "org.enhydra.instantdb.jdbc.idbDriver" );
               conn = DriverManager.getConnection(
"jdbc:idb:SupportCentralCalendar.prp" );

               conn.close();

          }
          catch( Exception err )
          {
          // Print out the error message
            System.out.println(err);
            err.printStackTrace();
          }
     }


     public static void main(String arg[])
     {
          objCreateDatabase = new CreateDatabase();
          System.exit( 0 );
     }

};


To compile I have a batch file like so:

javac -classpath
"c:\java\jar;c:\java\jar\idb.jar;c:\projects\support_central\database" *.java

to run it i have a batch file:

java -classpath
"c:\java\jar;c:\java\jar\idb.jar;c:\projects\support_central\database"
CreateDatabase

It compiles fine without any errors or warnings but when I run it I get the
following errors:

Exception in thread "main" java.lang.NoClassDefFoundError: CreateDatabase( wrong
name: org/enhydra/instantdb/CreateDatabase )
at java.lang.ClassLoader.defineClass0(Native Method)
at java.lang.ClassLoader.defineClass(Unknow Source)
..
...

Any ideas?  This is my first attempt with Instant DB and although there are
samples I'm not sure what I'm doing wrong herre.

Also, Do I really need "package org.enhydra.instantdb;"
on top?  Expecially if I'm not creating a package.  If I leave it out gives me
an error that "package org.enydra.instantdb" does not exist.
What happens if i'm adding this class as a package for another project does that
create a conflict?

Thanks for any information.
