hi all Friends

I am stuck using the java servlets and problem raise for classpath.

I had a problem with servlet to call a class because when i complied my servlet class file it give me error that it didn't found any java class (which is java class calling from servlet).

but i solved this problem by putting the path of classes to the classpath and then it worked fine after doing that and my all files compiled fine and my project worked.

But now i am again trying another project and trying to compile this project but got same problem again. Now this time i doing the all procedure for setting the classpath to solve the problem as i solved for previous project. but this time my classpath solution is not working for this project and i am trying this procedure again and again but i don't know i am stuck please help me friends

thanks in advance SANTBIR SINGH

    PrintWriter pw = response.getWriter();
    pw.println("<head><title>Hello World</title></title>");
