org.apache packages can't be resolved in Eclipse

Question

The following

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.StatusLine;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;

can't be resolved. I downloaded the Apache Http packages and imported them via the external jars option, but it still won't get resolved. In Android it seems to work, guessing its in the SDK, but here I'm not doing Android. Did I get the wrong packages?

I believe this is the link:

Apache

Answer 1

It sounds OK:

1) The .jar file in question should be something like "httpcore-4.0.1.jar". 
   Please confirm the name.

2) Adding this to "External Libraries" is absolutely the correct thing to do.

3) For compiling in the Eclipse IDE, you must:

   a) Select your project

   b) Select "Build Path" > "Add External Libraries"

4) For running in the Eclipse IDE, you must

   a) Select "Run" > "Run configurations".  
      Choose your (Java Application?) configuration.

   b) Select "Classpath" > "Add External Jar"

5) For running outside of the Eclipse IDE, you must make sure the .jar 
   file is present and your -cp (Classpath) argument is set correctly.

Answer 2

After dragging the jars into my project I was having the same issue.

Right-click on the jar and selecting Build-path -> Add-to-Build-Path worked for me.
