I have installed JSDK2.0 on machine to run the servlets. I have HelloWorld servlet in "C:\JSDK2.0\examples" directory. I am having problem compiling this servlet. I get the following error.

C:\JSDK2.0\examples>javac HelloServletWorld.java
HelloServletWorld.java:4: cannot resolve symbol
symbol : class HttpServlet
location: class HelloServletWorld
public class HelloServletWorld extends HttpServlet {
^
HelloServletWorld.java:6: cannot resolve symbol
symbol : class HttpServletRequest
location: class HelloServletWorld
public void doGet(HttpServletRequest request, HttpServletResponse response)
^
HelloServletWorld.java:6: cannot resolve symbol
symbol : class HttpServletResponse
location: class HelloServletWorld
public void doGet(HttpServletRequest request, HttpServletResponse response)
^
3 errors

I know there must error in setting the path and classpath variables. I set the path = "C:\jdk1.3.1_07\bin;C:\jsdk2.0\bin" and classpath ="C:\jsdk2.0\lib\jsdk.jar". Can anybody tell me what is wrong in the settings? Can help would be appreciated.

Thank you

You need to include the servlet.jar file in your classpath.

eg.  If it is in c:\jakarta-tomcat\commons\lib\servlet.jar

Use:

javac -g -classpath c:\jakarta-tomcat\commons\lib\servlet.jar HelloServletWorld.java

You might want to consider using the "-d" option too, to tell the compiler where to write the .class files

I am using JSDK server not tomcat server. I got it fixed. I set the path = "C:\jdk1.3.1_07\bin;C:\jsdk2.0\bin" and classpath ="C:\jsdk2.0\lib\jsdk.jar". I included the "import javax.servlet.http.*;" statement in my servlet. Thank you for your immediate response.

Thank you

Sorry.  I mis-read that as j2sdk :-(

You need to include the .JAR file that contains the javax.servlet... classes.  I'm not sure what it's called in JSDK.  Have a look to see what is in the \lib directory.

You can use the following to see what is in a jar file:

jar tvf filename.jar

I downloaded JSDK from http://java.sun.com/products/servlet/archive.html. I don't have servlet.jar , i only see jsdk.jar in lib directory .  I included the "import javax.servlet.http.*;" statement in my servlet and it works. Thank you guys for your comments.
