MultiPartEntityBuilder cannot be resolved to a type

I used a newer class to substitute a deprecated one. The class is MultiPartEntityBuilder. When i wrote it in the code, the compiler suggested me to import the following package
import org.apache.http.entity.mime.MultipartEntityBuilder;
I have imported it. But the compiler cannot still find it, giving me the error on the title
MultiPartEntityBuilder cannot be resolved to a type
So, it sounds quite strange to me. I've already succesfully imported similar packages
import org.apache.http.entity.mime.HttpMultipartMode;
import org.apache.http.entity.mime.MultipartEntity;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.entity.mime.content.ContentBody;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.entity.mime.content.StringBody;
Does it mean i have an old version which doesn't define any class named MultiPartEntityBuilder ?
How does the compiler know that i should import that class, part of that package, if he got an old version of that package?
Please note that
import org.apache.http.entity.mime.MultipartEntityBuilder;
is market as an error.

Upload Apache HttpClient Mime 4.3.1 jar file http://mvnrepository.com/artifact/org.apache.httpcomponents/httpmime/4.3.1

It means that org.apache.http.entity.mime.MultipartEntityBuilder isn't accessible during compilation time. You should add it to your project somehow depends on your build tool.

Looks like a spelling error, you had MultiPartEntityBuilder instead of MultipartEntityBuilder. The "P" shouldn't be capitalised.

Can't Import packaged class files from a jar in jython when it contains classes in the default package

I am working on a program that needs to import a jar that has classes both in the default package (root of the jar) and in packages.
So far I have this code and it works so i can import the ones in default but it fails when trying to import ones on packages.
import sys
import os
sys.path.append(os.getcwd() + "/versions/1.7.2.jar")
If I run import a (a is a class as this is a Obfuscated jar.)
it imports but if I run import net.minecraft.server.MinecraftServer it does not work it says No Module named net.
Which I know the class and all packages around it is there so any help?

The problem is that Jython does not correctly find the code.
The source code is based on files like a.class wich you can import but not net.minecraft.server.MinecraftServer.

how to import com.android.camera package in a java project

Hi I am writing a test using UIAutomator API , however in my java project I want to import the com.android.camera package.
However I am always getting an error that this import cannot be resolved.
I have added the android.jar in my build path and rest of the things work fine.
However I am not able to import this package.

There is no such package in android, maybe you are looking for
com.android.hardware.Camera
class ?
if so try
import com.android.hardware.Camera;

The camera class resides inside the below package so try to import below package instead of com.android.camera add the below.
import android.hardware.Camera;

import android.hardware.Camera;
try to place it after your package name

If you are using Eclipse than just press Ctrl + Shift + O Eclipse will automatically add the required libraries in your source code. If still you are getting import issue than you need to check if you are using correct API or the spelling is correct.

Import issue in Eclipse

I have the following import in my java code in an eclipse project
import org.jscience.*;
However upon writing the code
Real r1 = new Real.valueOf(1);
I receive the error
Real cannot be resolved to a type
I am puzzled as to why this is happening as I am correctly importing (or so I believe)
Also to note, eclipse suggests using
import org.jscience.mathematics.number.Real;
But I am trying to avoid using the import for the full class location within the Jar.
Any ideas?
Thanks in advance
Martin

Try
import org.jscience.mathematics.number.*;
Because
import org.jscience.*;
will actually only import classes from within the jscience package and not any subpackages.

If we suppose your import is not throwing errors, try importing g.jscience.mathematics.number.*.

Which version of Netty API does this example code use? Unable to resolve io.netty.handler.codec.http.DiskFileUpload with 3.2.x

I came across this sample code for handling file uploads with Netty, this looks perfect, just what I needed. Unfortunately I am having difficulty incorporating this class as many Netty API features are unresolved. One of them for example is io.netty.handler.codec.http.DiskFileUpload, I am unable to find this in any of the online API docs for 3.0,3.1.3.2.
The class I am having issues with is here:
https://github.com/netty/netty/blob/master/example/src/main/java/io/netty/example/http/upload/HttpUploadServerHandler.java
I have tried using netty-3.2.5.final, 3.3.1.final, 3.4.0.Alpha
Unresolved imports:
import org.jboss.netty.handler.codec.http.HttpPostRequestDecoder.EndOfDataDecoderException;
import org.jboss.netty.handler.codec.http.HttpPostRequestDecoder.ErrorDataDecoderException;
import org.jboss.netty.handler.codec.http.HttpPostRequestDecoder.IncompatibleDataDecoderException;
import org.jboss.netty.handler.codec.http.HttpPostRequestDecoder.NotEnoughDataDecoderException;
import org.jboss.netty.handler.codec.http.InterfaceHttpData;
import org.jboss.netty.handler.codec.http.InterfaceHttpData.HttpDataType
import org.jboss.netty.handler.codec.http.HttpDataFactory;
import org.jboss.netty.handler.codec.http.DiskAttribute;
import org.jboss.netty.handler.codec.http.DiskFileUpload;
import org.jboss.netty.handler.codec.http.FileUpload;
import org.jboss.netty.handler.codec.http.DefaultHttpDataFactory;
import org.jboss.netty.handler.codec.http.Attribute
Any help appricated

When you see the org.jboss.netty namespace, that indicates v3.x
io.netty is used in v4.
Online documentation is located at http://netty.io/docs/

It's under master branch which is 4.0.0.Alpha1-SNAPSHOT from the pom.
