How to connect to cloudscape?

Question

Hi there
I wrote a simple program just to check how connection to cloudscape works.
import java.sql.*;
public class DBTester{
public static void main (String [] args){
try{
Class.forName("com.cloudscape.core.RmiJDBCDriver");
}catch(ClassNotFoundException e){
System.out.println("Exception");
e.printStackTrace();
Connection con =null;
Statement st =null;
ResultSet rs =null;
try{
con = DriverManager.getConnection("jdbc:cloudscape:rmi:CloudscapeDB","","");
st = con.createStatement();
rs = st.executeQuery("select oid from MOTABLE ");
while(rs.next())
System.out.println(rs.getString("oid"));
}catch(SQLException e){
System.out.println("SQLException");
e.printStackTrace();
finally{
try{
rs.close();
st.close();
con.close();
}catch(Exception e){
System.out.println("Couldnt close !");
e.printStackTrace();
but I get the following exception
java.lang.ClassNotFoundException: com.cloudscape.core.RmiJDBCDriver
at java.net.URLClassLoader$1.run(Unknown Source)

at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Unknown Source)
at DBTester.main(DBTester.java:7)
my classpath looks like this
javac -classpath %CLOUDSCAPE_HOME%\lib\cloudscape.jar;%CLOUDSCAPE_HOME%\lib\cloudutil.jar;C:\j2sdkee1.3\lib\j2ee.jar;. DBTester.java
and j2ee_classpath is
J2EE_CLASSPATH=.;C:\Inprise\vbroker\lib\vbjorb.jar;C:\VisualCafe\bin\mbean_design;C:\j2sdkee1.3\lib\cloudscape\RmiJdbc.jar;C:\j2sdkee1.3\lib\cloudscape\cloudclient.jar
Please Help me

Hi,
Just check the CloudScape's JDBC driver's class name. It's COM.cloudscape.core.RmiJdbcDriver.class.
In Java both package name and class names are case sensitive.Change it and then try to connect to cloudscape database(which is there in cloudclient.jar).
Hope this helps.
