How to include jars in command line classpath?

when i am compiling a servlet in a command line,as
C:\doct\document\filter\WEB-INF\classes>javac filter.java
its says HTTP request and response is not recognized.

previously there was a method which i have done to fix this problem,but i forget that procedure,somthing i remember,i us to copy some file from apache tomcat to some other location.
i have tomcat6,its working,all enviornment varible has been set.

thank you.

You should not have to copy any files. SImply add the jar files, where they sit, to the command line classpath.

yaa i think it was jar files.
where i would get it from.From apache tomcat folder??
please specify the path where those jar files are found in apache tomcat folder.

It's called servlet-api.jar, if memory serves. A quick file search will find it for you.

i need the exact location of those jar files.
i have done it before,but i forget it now.
its in the apache tomcat folder,somwhere i don't know where.

the errors which i am getting.

Yes, that means you need to include the servlet jar file. Show some initiative and look in your Tomcat folder structure to find it.

ok i found servlet jar files,where i need to place it.

Nowhere. Just include the jar file in your command line.

If you don't know how to do that, just say so and I'll move this to the Beginning Java forum.

no i dont know...

OK, I'll move this to the appropriate forum with a change of subject.

Abhishek,

Compile --> "javac -cp <jar_ file_name> <java_file_name>"
Run ---> "javac -cp <jar_ file_name>;.; <java class>"

thank you anila for your reply.
but i fixed the problem in some other way,i copied all the jar file from the tomcat home to the jave lid/ext folder as the result the above problem is solved,no need to set the class path.
really coool.
thanks again to all Bear Bibeault too.
