I started my project in servlets , Now I can't convert to JSPs.
Including javascript in servlets is becoming very headache for me...Why can't you convert to JSPs? Trust me, you don't want to be doing this in servlets, it's madness. Begin with JSPs immediately, you'll save more time and effort and frustration than you can imagine.

I got a new problem
out.println("<form name=frm1 action=Cone>");
out.println("<input type=\"submit\" value=\"Submit\" onClick=\"validate()\" >");
out.println("function validate()");
out.println("{");
out.println("if(document.main.name.value==\"\"||document.main.address.value==\"\")");
out.println("alert(\"Please Enter Your Username and Password\"\n)");
out.println("}");Now whenever Submit button is clicked "validate()" is exceuted and an alert box is shown. and servlet is also executing
How can I stop servlet to execute when validate is executed..This is a JavaScript problem, not the right place for it.
You need to return true/ false from your JavaScript function depending on if you want to allow the action or stop it.
And where the function is called make a change:
<input type="submit" value="Submit" onClick="return validate();" >The return keyword will pass the value returned by validate() to the onClick() event handler and stop the propogation of the submit event if the value is false. If it's true,it'll continue.
And please, once again, for God's sake, do yourself a favour and switch to JSPs!
