DataSource class not found

[Kerry Wilson]

I am getting a class not found exception when compiling a servlet, on a DataSource object. Specifically on this line:

class ByteArrayDataSource
   implements DataSource
{

Ihave imported the following packages:
import java.io.*;
import java.util.*;
import java.util.regex.*;
import java.sql.*;
import java.text.*;
import javax.mail.*;
import javax.activation.*;
import javax.mail.internet.*;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.sql.*;
import javax.naming.Context;
import javax.naming.InitialContext;
What package do I need?

Ahh it is the little errors that cause some much trouble.

DataSource is defined in the
javax.activation and javax.sql packages.

I would suggest you re-define your class to:

 class ByteArrayDataSource implements javax.sql.DataSource{ 

or

 class ByteArrayDataSource implements javax.activation.DataSource 

[Kerry Wilson]

I have imported the javax.sql.* and javax.activation.* packages.
Just in case I tried importing javax.sql and javax.activation, but got the javax/sql and javax/activation cannot find type errors.
My class path contains following .jars
rt.jar, tools.jar, servlet.jar

[Craig Jackson]

Oh, okay. I guess I misunderstood your error message.
The packages below are found in a jar file called j2ee.jar which can be accessed through Java's Enterprise Edition(J2EE) which you can download from Sun's website. I can't remember the exact path but it is something like %j2ee_home%\lib\j2ee.jar. The serlvet.jar file contains packages relating to jsp/servlet.

import javax.mail.*;
import javax.activation.*;
import javax.mail.internet.*;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.sql.*;
import javax.naming.Context;
import javax.naming.InitialContext; 
 

I hope this helps.

I noticed activation.jar was not in my class path and also made the suggested changes and it works now thanks.
