"The type Java.util.Map$Entry cannot be resolved"

Question

I have created a web project in eclipse, which works fine, but when i add the Hashmap it gives me the error The type Java.util.Map$Entry canot be resolved.

I have seen many discussions on the same issue but could not get a solution. Can someone help me please.

package com.balu.loginApp.bean;

import java.util.HashMap;
import java.util.Map;

public class LoginAuthenitication {
    Map<String, String> users = new HashMap<String, String>();

    public LoginAuthenitication()
    {
        users.put("balu", "Balamurali CL");
        users.put("swathi", "Swathi RL");
    }

    public boolean loginAuthenitications(String userName, String passWord)
    {
        if (passWord== null || passWord.trim() == "")
        {
            return false;
        }
        else
            return true;
}

What version of Java are you using to a) run the program b) compile the program c) run Eclipse? — Thilo, Aug 02 '16 at 04:02
Can you also post a full stacktrace? This is a runtime error, right? What servlet container are you using and at which version? — Thilo, Aug 02 '16 at 04:06

Neither your title nor your code has anything whatsoever to do with your question. — user207421, Aug 02 '16 at 06:16
The function should contain `return passWord != null && !passWord.trim().isEmpty();` as `== ""` is a wrong string comparison (should use `equals`). — Joop Eggen, Aug 02 '16 at 06:27

Please follow this instructions

Right click on the project.

Click 'Properties'

Go to 'Java Build Path'

And then: 'Libraries'

In there, Click: Add External Jars

Add: ''Path/To/Tomcat/Bin/tomcat-juli.jar

After reading the stacktrace you provided , it has nothing to do with Java.util.Map$Entry.

error from stacktrace :

java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory

possible solution

Tomcat's bootstrap.jar used to reference the file bin/tomcat-juli.jar in it's manifest. That is changing since it forced tomcat to use a specific library. Instead, it has to be added to the -classpath line. Open your server configuration, and add tomcat-juli.jar to the classpath, and it will work.
