I try to call functions in javascript with java program.  I found some information and tried implement it.  However, I got this error message," [ERROR] Line 5: The import javax.script cannot be resolved".  What's wrong with my code?

I am using JRE 1.6.0.13 with eclipse.
package com.xenia.googleproject.server;
 

import javax.script.*;

import com.xenia.googleproject.client.GreetingService;

import com.google.gwt.user.server.rpc.RemoteServiceServlet;
 
 

/**

 * The server side implementation of the RPC service.

 */

@SuppressWarnings("serial")

public class GreetingServiceImpl extends RemoteServiceServlet implements

		GreetingService {
 

	public String greetServer(String input) {

		String serverInfo = getServletContext().getServerInfo();

		String userAgent = getThreadLocalRequest().getHeader("User-Agent");

		return "Hello, " + input + "!<br><br>I am running " + serverInfo

				+ ".<br><br>It looks like you are using:<br>" + userAgent;

	}

	

	public String getClientAddr(String latitude, String longitude, String city, String country, String country_code, String region){

		String addr = new String();

		ScriptEngineManager mgr = new ScriptEngineManager();

		ScriptEngine jsEngine = mgr.getEngineByName("JavaScript");

		Invocable invEngine = (Invocable)jsEngine;
 

		

		try{

			jsEngine.eval("function getClientLocation(lat, lng, city, country, country_code, region)"

					);

			invEngine.invokeFunction("getClientLocation", latitude, longitude, city, country, country_code, region);

		} catch (ScriptException ex){

			ex.printStackTrace();

		} catch (NoSuchMethodException ex){

			ex.printStackTrace();

		}

		addr = city;

		

		return addr;

	}

}

Most likely you have Eclipse set to 1.5 compiler settings rather than 1.6, causing it to not recognise any of the 1.6 specific packages.
Just because you have a 1.6 JVM installed on your system doesn't mean your IDE will use that (especially if it's Eclipse).

How can I be sure which version Eclipse recognize?  Where should I lookup to?  I try to figure which version Eclipse have from "Project>Properties" but I did not see anything like 1.5...Did I miss something?

Its the compiler settings. change it from 1.5 to 1.6
I think there are around 3 sections to change in eclipse.

To make it simple, just remove or uninstall 1.5 & 1.6 & Install 1.6
This should help.

What I meant was the 'Compiler' The executable & the runtime classes.
Somehow eclipse got that mixed up, & Im very sure you have 2 JDK's running.

I had this problem in MacOSX 10.5 before, the strange thing is that if I compile the Code from command line, it works well.
If you cant compile from command line, theres more than the eclipse configs.
Perhaps your Environment settings is not correct?

It a simple problem thats hard to detect, I strongly suggest to remove & reinstall the JDK 1.6
