Hello Mark
I think you are right Mark when You say that, it is do finding the
db2jaa.jar/zip file
but question is why it is not getting "COM.ibm.db2.jdbc.app.DB2Driver"
which is placed in db2java.zip/db2java.zip.jar file.
This is the source code of the file I am trying to run undr tomcat
import java.sql.*;
import java.lang.*;
import java.io.*;
public class Ndb2servlet{
public static void main(String args[]) {
try{
Class.forName
("COM.ibm.db2.jdbc.app.DB2Driver").newInstance();
}
catch( Exception e)
{
System.out.println("\nDriver class not found
exception");
}
try{
Connection con = null;
// URL is jdbc:db2:dbname
String url = "jdbc:db2:sample";
if (args.length == 0)
{
// connect with default id/password
con = DriverManager.getConnection(url);
}
else if (args.length == 2)
{
String userid = args[0];
String passwd = args[1];
// connect with user-provided username and
password
con = DriverManager.getConnection(url, userid,
passwd);
}
else
{
System.out.println("\nUsage: java Ndb2servlet
[username password]\n");
System.exit(0);
}
// retrieve data from the database
System.out.println("Retrieve some data from the
database...");
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * from
db2admin.employee");
System.out.println("Received results:");
while (rs.next())
{
String a = rs.getString(1);
String str = rs.getString(2);
System.out.print(" empno= " + a);
System.out.print(" firstname= " + str);
System.out.print("\n");
}
rs.close();
stmt.close();
con.close();
}
catch (SQLException e1)
{
System.out.println("SQL Exception: "+ e1.getMessage
() + "\n");
}
}
}

If your db2driver.zip/jar file was not being found, then it would through a
ClassNotFoundException. Your error is due to using an invalid connection
string for the kind of driver you are using. For example, using the
following combination will through a no suitable driver exeception:
String conn = "jdbc:db2://obtasdne/FLBP";
Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");
con = DriverManager.getConnection(conn);
This is an example of where you should use the .net driver. Check your
connection string. That's where your problem is

Hello Mark,
I am currently using "COM.ibm.db2.jdbc.app.DB2Driver" driver to run my
simple
java program for establishing DB2-Tomcat connectivity.
I tried changing it to "COM.ibm.db2.jdbc.net.DB2Driver" still it says,
No suitable driver
I think my tomcat is not able to find out db2java.zip file which is placed
in
C:\Program Files\SQLLIB\java
DO I need to add some contextpath in server.xml of TOMCAT to tell tomcat to
look for
DB2 jdbc driver in %SQLLIB%\java directory?
I was looking at server.xml in TOMCAT and found that there is something
called <Realm />
comment above which says
<!-- Replace the above Realm with one of the following to get a Realm
stored in a database and accessed via JDBC -->
I tried changing it to DB2 compatible information..but didn't worked...I
had problem starting tomcat...
Can you guide me in some other way?

Who's DB2 jdbc driver are you trying to use? If you're using the IBM
implementation, you can either load the
"COM.ibm.db2.jdbc.net.DB2Driver" or the "COM.ibm.db2.jdbc.app.DB2Driver" If
you use the wrong one, you will get a No suitable driver exception. The
correct one depends on the situation, and in this case it's probably the
.net one.

Hello John,
It was a nice thinking but I didn't worked.
It is not finding the driver even now...I tried printing the
classpath..though it shows the
all 3 ".jar" files included but it is working only in %SQLLIB%\bin
directory that is if I try to run my file by keeping it in %SQLLIB%\bin
directory
it worked fine and retieve resultsets from database but
not from TOMCAT_HOME directory...
Any other tries..?

Try renaming your .zip files to .jar files. Just change the extension from
.zip to .jar without changing the files themselves.

Hello everyone...
thanks for showing interest in the list and to make it grow...
I have a situation here.
I am using tomcat 4.0.3 and jdk 1.3.1_04. I want to write a soap
service which will bring the resultset from IBM DB2 database.
Before implementing soap I am writing a simple Java "Ndb2servlet.java" file
inside
%TOMCAT_HOME%\webapps\soap\WEB-INF\classes
Now it compile fine but when I try to run it it says:
>>>>> COMPILING >>C:
\jakarta-tomcat-4.0.4\webapps\soap\WEB-INF\classes>javac Ndb2servlet.java
>>>>> RUNNING >>C:\jakarta-tomcat-4.0.4\webapps\soap\WEB-INF\classes>java
Ndb2servlet
SQL Exception: No suitable driver
I have tried to put db2java.zip, runtime.zip and sqlj.zip in %TOMCAT_HOME%
\common\lib and
and also included in system classpath then restarted TOMCAT but still it
couldn't find driver.
DO I need to do something special for my JAVA file in tomcat to find
"DB2driver"
Please help....
thanks
