Hi guys I just clean and build my project in Netbeans, copy the folder of my project, put it in a ZIP archive and send it to myself. Now I don't know how to deploy the project, I tried just to copy the classes and run it, but it give me so many error, even if I try to recreate the structure of the packages with the same name it doesn't work. I tried to find information on the internet but is not very clear.
When I click on Clean and Build.
NeatBeans create a folder with the name of the project and inside> build,dist,nbproject,src,web,build
When you clean and build under Netbeans, you should find all you need under the dist folder:
if you a creating a web application you should find a .war file - that is the file to deploy: just copy it to the webapps folder for Tomcat
if you are creating a standalone application or a library, you should find the .jar
Above assume you do not use maven for the project. If you did you would not have a dist folder, but the standard maven target one.
I don't really know what are the errors you get. However check these few things out and see if it works for you:
check if you are importing from an external Library, if so, make sure that you have those libraries within your project.
If you are creating a new project and just copy pasting the classes, then make sure packages are correct and not from the other project you had.
it is pretty simple to open a project in net beans:
after creating your project and building it, zip the whole project folder.
once you unzipped it, use "CTRL+Shift+O" or the third option in netbeans>file to open a project.
a filechooser should open and you can select the project you want to open.
this is pretty much the whole thing you need to do.
you can also find the .war in webapps folder, .jar in dist folder too.
your question is really unclear. We dont know what is your project exactly nor your errors.
Please let me know the exact errors. so that I can help you with better.
I don't understand exactly what is the error your facing but I think that if you use the export and import project features of NetBeans maybe you wouldn't have that error in the first place:
To export project:
go to File -> Export Project -> To ZIP... -> Specify the zip destination directory.
To import project:
go to File -> Import Project -> From ZIP... -> And browse your file system to find the zip you previously created.

So I have an Eclipse project I have been working on for quite sometime now and my program that backs up the project hasnt been doing it for months, and I never bothered to check the back ups (stupid me). Well the project got corrupt and I lost all the files and dont have a back up that is even close to up to date. However I do have the jar file that is fairly recent (it only contains .class files) and I was curious if anyone knew how to convert a jar file with .class files into an eclipse project. Thanks for the help!
You can follow the steps given below:
Make sure you have a working decompiler in eclipse. If not, please install https://marketplace.eclipse.org/content/enhanced-class-decompiler into your eclipse.
Create a new Java project in eclipse > Right-click the src folder > Click import > Select Archive from the list to import your JAR
Expand the JAR in eclipse and double click a class file to decompile it.
Recently I worked on a project on a mac, using eclipse. When I was done with the project I copied certain .java files and their corresponding .class files onto a USB drive and brought it to my personal computer. When I try to use the import feature on eclipse and import everything, my main method is not recognized by eclipse. It will work if I create a new eclipse "class" by the name I have in the program and copy paste the code. I have many classes so I can not do this for each one. Is there any way for me to change all .java/.class files into files that will be read by the system?
Thanks
An eclipse project contains a lot of meta information. Just open the project directory in a file browser, and have a closer look. There are files like .classpath for example.
When you just copy your source code, you leave all the meta information behind!
You should either copy the complete project directory, or simply use the export task to create a ZIP file of your project. (to later import that in other systems).
There is one other way you can do this. Just create a new project with the SAME EXACT PROJECT NAME that you did at school or wherever. After you create your project, go to your file explorer and navigate to the following place:
<"Directory to work-space">/<"Project Name">/src/
For ex: in Windows, it is Generally:
C:/Users/your_name/workspace/projectName/src
In here, copy all your ".java" files.
Now go to eclipse, right click on your project and hit refresh. You will find all your .java files there. Right-click on your project and hit "Run"->"Run as a Java Project". It should run! hope this helps.
PS: You do not need your class if you are executing it in Eclipse. Eclipse will create its own class files.
I am trying to import a projetc (in ZIP file) in my netbeans. It is downloaded from GitHub (link: https://github.com/varavell/OnlineBookStore). While importing the project from Zip it shows the error and no project becomes imported. At the same time, at the bottom right corner it keeps unpacking of the project (never finish it though). Why this happening and how can I run a complete project into netbeans?
The worning is:
This warning (No NetBeans projects added) can happen if the zip file was created manually. To avoid this create the ZIP file in NetBeans using File > Export Project > To Zip...
Unzip your project and then open Netbeans. Go to File > open > your project file
You need to have one of the projects that Netbeans recognizes in the zip file.
This particular project has no pom.xml, build.xml or nbproject directory.
You will need to create a new project of the appropriate type and extact/copy your sources from the zip into it.
It's not possible to know what the problem is from the information you're providing.
It might be that the zip is corrupted, that the zip is not correct, that the zip contains a project in an unrecognized format, or that it's a bug with netbeans, for example.
You need to provide the NetBeans' log at least. I'm currently on cellphone, so i can't tell you where to fimd it, but you can find it yourself after a simple google search.
As for an immediate solution, since the project is on GitHub, you can simply clone the project using Git (inside NB). Or create a new project and manually replicate the files from the source-codes and file-structure visible on GitHub.
If you try to import a web project. first of all plugin web tools JSF, RichFaces etc. and then you will import your NetBeans web files.
and then Export Project > To Zip.
You should extract your project from the zip first. Then add it from file system.
I am new to Java so please forgive me if this has a simple solution (and I hope so though). I have added previously coded .java class files to my existing project in eclipse, while trying to import com.abc. and ctrl+space it even shows these packages and classes.
However when I try to compile it says "package xxx does not exist". I've spent hours researching on this but most of the solutions focus on .JAR files and I don't have a jar file. I even tried creating a .JAR file and then importing but I think I couldn't manage to success that.
I really need help about this and thanks for your help.

First of all you need to understand how to add jar files in eclipse project. You can place you're jar files in webinf lib folder.
And after that you can configure the project build path. By
Right click on project (in eclipse project explorer) > buildpath > you find configure build path.
My friend sent me a project from his eclipse workspace for me to take a look at, however when I tried to put the folder in my workspace it did nothing. I opened eclipse and nothing was there. So i tried to make my own project and just put the .java and .class files in their respected folders, but it still didn't work. Is there some special way I have to transfer them? I should also mention he has a windows computer and I have a mac if that makes any difference for file types like that. Thanks for the help!
If you can just take the .java files and paste them into your 'src' folder in a new eclipse project, you should have no issues. Just make sure you refresh your project in eclipse(right-click on project folder and click refresh, or click on it and hit f5).
This is what i normally do.
Suppose your eclipse workspace is D:\EclipseWorkspace and your project name is Project1.
Then i would copy Project1 in eclipse workspace on disk to have D:\EclipseWorkspace\Project1.
Then create a new java project in eclipse and when prompted for name provide name as Project1 (exactly same) and say finish. It will import the project automatically. Everything should be up :)
