I am learning JavaFX from Pro Java FX 2 book. I am trying to import javafx.builders.* package. but compiler keeps raising errors import cannot be resolved. but other packages javafx.* excepts javafx.builders.* imports successfully. I am using JavaSDK 7u51. I tried in eclipse with e(fx)clipse and Netbeans as well. Please help me to find solution.
There is no such package as javafx.builders. Each builder is (generally) in the package of the class it builds, for instance GroupBuilder is in javafx.scene, as:
import javafx.scene.GroupBuilder;

I have installed PlantUML and added the classpath to it. However, the following import keeps giving me an error in eclipse.
import net.sourceforge.plantuml.SourceFileReader;
It says The import net cannot be resolved
What could be the possible solution to this?
I imported the samples of Sphero-Android SDK to my workspace. TwoPhonesOneBall project gives compiler errors. In ConnectionActivity.java class, the following imports cannot be resolved.
//...some imports
import orbotix.multiplayer.LocalMultiplayerClient;
import orbotix.multiplayer.MultiplayerControlStrategy;
import orbotix.multiplayer.MultiplayerGame;
import orbotix.multiplayer.RemotePlayer;
//...imports
How can I fix it? Since these classes don't exist, I didn't come up with a solution. I searched the net but I couldn't find similar problem. By the way,the same problem also occurs in MultiplayerLobby application.
In my Xpage, I have added to Java classes. One is "AUser" declared in Models package and one is "AUserRepository" declared in a Repository package.
When I try and import AUser into a class in my AUserRepository... the import statement I type in is not working.
import com.Discussion.utils.AUser;
Weird thing is, If I exit out of Notes and load up eclipse standalone, and make the same kind of stuff, the import works fine. Am I missing out some important factor in Xpages?
The problem definitely is the import routing.
import Models.AUser;
import Repository.AUserRepository;
Is the project build path correct? Project - Properties - Java build path. Also, have you tried cleaning the project? Project - Clean....
I'm using Netbeans IDE 7.0.1.
I base my question on the CalculatorApp sample application available with the IDE.
The sample is running fine but I wish I could use some JSON, ad so I download google-gson-stream-1.7.1.jar library, and included it in my libraries :
- right click on "Library", then "Properties" then "Add JAR/Folder" and selected my JAR (located somewhere in "My Documents/Download".
The problem is that when i type the following :
import com.google.gson;
(or even com.google), the IDE fires a "Package com.google does not exist". The JAR and its hierarchy is correctly shown on the left side pane,in the "Libraries" section. Most surprising, the IDE can autocomplete the com.google.** stuff.
AFAIK, I need to further to get this work, don't I ? Any ideas ?
Thank you !
In Java, import statements are for classes and interfaces (types) not for packages themselves. Are you sure you tried to import a class under com.google.gson package and not the package itself?
import com.google.gson.Foo; should work.
So should
import com.google.gson.*; or
import com.google.*;
Note however that wildcard imports aren't particularly recommended.
I am using:
import com.google.gson.Gson;
When I develop an RMI server, I use:
import java.rmi.server.UnicastRemoteServer;
import java.rmi.server.StubSecurityManager;
import chat.server.*;
But when I compile the Java file, an error occurs that says:
Class java.rmi.server.UnicastRemoteServer not found in import. import
java.rmi.server.UnicastRemoteServer
and also error with StubSecurityManager. Please help me work out this problem.
It appears that you are using an old code written in JDK1.1 trying to compile using newer version of JDK.
You need to make following changes.
java.rmi.server.UnicastRemoteServer -> java.rmi.server.UnicastRemoteObject
java.rmi.server.StubSecurityManager -> java.rmi.RMISecurityManager
