I can't compile this, why?

Question

I do not possess any means of compiling any .java file that imports javax.* or anything J2SE-related, thus, I have to compile it remotely on a remote host (www.myjavaserver.com), however, for some reason this file will not compile but will not produce any errors, warnings, or any display of any kind - but no .class file is ever found.
import java.io.*, java.util.*, javax.servlet.*, javax.servlet.http.*;

public class RequestParameterResetter extends HttpServletRequestWrapper {
    private HttpservletRequest origRequest;
    private Map<String, String> parameterMap;
    public RequestParameterResetter(HttpServletRequest request) {
        super(request);
        origRequest = request;
        parameterMap = new HashMap<String,String>();
    public String setParameter(String key, String value) {
        String oldValue = parameterMap.put(key,value);
        if (oldValue == null) oldValue = origRequest.getParameter(key);
        return oldValue;
    public String getParameter(String key) {
        String value = parameterMap.get(key);
        if (value == null) value = origRequest.getParameter(key);
        return value;
}Could someone tell me what I'm missing in order for this to properly compile?
Thanx

Sorry I can't do that, as much as I want to. My
computer is very ancient and has too little memory to
run any kind of server program, especially a
Java-related one. I tried with Eclipse a while back
(2 years ago and never figured it out, way too hard
in spite of my PC's inability to interact with it)
nearly destroyed my machine with it.You actually don't need to run any server. You just need to get the .JAR files (you should try to get the same server and version that you deploy on ... but that may not be possible). Then you put them in your Java Classpath, and you will be able to compile (from command line, or whatever). You could then un-install the server if you wanted to...

That means I can only compile J2SE formatted classes
remotelyThat would be J2EE. J2SE is the standard edition, where you get the compiler, java.lang.String, java.util.Date, and all the rest of the core stuff. J2EE is the enterprise edition for getting the javax.servlet packages (among others).
More comments on how you might change added as comments in the code...
on www.myjavaserver.com - provided it is
working.
I made the changes necessary and still can't compile
it!

The class is a Java 5.0 class, it won't compile to JSDK 1.2.
Ask myjavaserver.com to see how you can get ahold of the error logs so you can see what messages are generated.
