I am learning how to use wicket. I found this example, which I am trying to implement, but I`ve stumbled upon a problem with wicket.version.undo package. In the example, Change class from this package is used for pages versioning.
But when I try to import this package I get an error: The import can not be resolved
So I was wondering whether this package was replaced with something else in newer versions of the wicket? (my version is 7.6.0). Because I have found the jar of this package only for up to 1.6 versions.
I would be very grateful if someone could help me with this.
This article is very old!
The easiest way to solve such kind of issues is to remove the import from the code. This way the IDE will try to find the missing classes for you. If the classes are not available on the current classpath then modern IDEs will try to find it in Maven Central and suggest you to add another dependecy to the class path.
I don't have the IDE in front of me but I think the classes you need are in wicket-util module.

I was trying to switch my project from java8 to java11. While switching I am facing the below errors:
Package accessible from more than one modules.
cannot be resolved to a type/variable. (Here is an dependent library)
I was looking forward for solution to resolve this. It will be helpful if I got any working example to understand better.
I can not figure out what I am missing solve this import error. I have org.eclipse.ui_3.107.0.v20150507-1945.jar included in my build path, but it does not seem to be what is required. I've tried including all the other org.eclipse.ui.* jar files in my build path but none seem to be resolving the import error. Does any one know what is needed for this?
I'm a relatively new java developer, but have run into the "The import * cannot be resolved" quite a bit and the only way I've found to fix it, if it can't be auto resolved with eclipse's quick fix, is to try and guess what jar needs to be added to the build path. Is there a more reliable method or is trial and error what it comes down to?
This is an internal class (the package name includes 'internal'). You should not be trying to use it. Internal classes are often created / changed / deleted without warning between Eclipse releases.
See Eclipse API Rules of Engagement for more information about the Eclipse API.
This particular action existed in Eclipse 3.x but is no longer present in Eclipse 4. The action essentially calls IWorkbenchPage.showView, you will have to write your own action to do the same.
I'm working on a Netbeans project and I'm trying to import these packages but It doesn't exist
Error Displayed
could someone tell me how to fix this problem
Thank you
Whenever you cannot find a package, you should download it from its source and then add it to your project. Here you can take a look at jOOQ/jOOL. As about the other two, make sure you are using Java 8. You will also need to know how to add packages to your projects in the future.
I'm new to using freebase, so I'm going through the java sample provided on the Developers page. But when I run the code, I get errors because eclipse cannot recognize the packages that I'm importing. Does anyone know where I can download these packages in order to import them without errors. So my question is, where can I download the package com.freebase.samples
I've looked everywhere for the package but can't find it anywhere, is it discontinued and replaced by a newer package, if so does anyone know the name of the new package and where I can find it.
I don't know if this is what you are looking for, but the files have the package com.freebase.samples.

I am using NetBeans 7.4 with JDK 7u51.
When I try to compile the below statement:
package userclasses;
import java.net.URLEncoder;
etc... Other imports.
etc... Normal class definition.
I get this compile error message:
error: cannot find symbol
import java.net.URLEncoder;
symbol: class URLEncoder
location: package java.net
If I take the import java.net.URLEncoder out of the file then it compiles fine.
I have tried clearing the NetBeans cache.
The only thing I can think of is that the compiler is searching the wrong java.net library.
I am using codenameone libraries and one of them contains a java.net definition with only a few classes in it. I am not sure if this is legal? Seems like that could obscure the JDK's java.net library? However, I completely removed that library from the project and still get the same error, so that discredits my theory a bit, though it could be defined somewhere else that I am unaware of.
I am open to any suggestions?
BTW does any know which physical library file java.net classes are located in?
I was thinking of adding that .jar to my project and placing it first on the classpath (I know that it is included with the JDK by default), that way I would know for sure that the correct java.net was being searched.
This is frustrating stuff as my development work has ground to a complete halt because of this.

It turns out that java.net.URLEncoder is not supported with codenameone platform, at least not as of version 2.0. Codenameone has a class called com.codename1.io.Util.encodeUrl that works.
