When Eclipse builds my workspace, I assume that it creates Java .class files. What else should otherwise deploy to my running JBoss AS?
Do you know where I can find these class files that Eclipse temporarily creates?
Right click on your project, and then click on properties. Now click on the Java Build Path section, and you will be able to see and set the Default output folder on the "Source" tab. I believe Eclipse defaults to "bin"
More than likely though, it won't be enough to just copy these over to JBoss. You'll need to deploy your application as a .war file, which is basically a .zip with a different extension. Do some googling on "ant war task" for some examples and articles.
As gregcase has said, you want to deploy a .war file, and if you want Eclipse to do this for you, just right-click on the project, select "export" and under "web" choose "WAR file."
Copy this file to $JBOSS_HOME/server/default/deploy/ and you should be set.

I have a java application in eclipse and the thing is that some of the jar files within the project are grayed out.
What does this mean?
The project runs as expected and they are set correctly within the build path.
These (JAR) files are not under version control (if using Git, these files has been added to .gitignore, e. g. via right-click Team > Ignore).
How do I import a jar in Eclipse?
You can add a jar in Eclipse by right-clicking on the Project → Build Path → Configure Build Path. Under Libraries tab, click Add Jars or Add External JARs and give the Jar. A quick demo here.
The above solution is obviously a "Quick" one. However, if you are working on a project where you need to commit files to the source control repository, I would recommend adding Jar files to a dedicated library folder within your source control repository and referencing few or all of them as mentioned above.
Adding external Jar is not smart in case you want to change the project location in filesystem.
The best way is to add the jar to build path so your project will compile if exported:
Create a folder called lib in your project folder.
copy to this folder all the jar files you need.
Refresh your project in eclipse.
Select all the jar files, then right click on one of them and select Build Path -> Add to Build Path
Two choices:
1/ From the project:
2/ If you have already other jar imported, from the directory "References Libraries":
Both will lead you to this screen where you can mange your libraries:
Here are the steps:
click File > Import. The Import window opens.
Under Select an import source, click J2EE > App Client JAR file.
Click Next.
In the Application Client file field, enter the location and name of the application client JAR file that you want to import. You can click the Browse button to select the JAR file from the file system.
In the Application Client project field, type a new project name or select an application client project from the drop-down list. If you type a new name in this field, the application client project will be created based on the version of the application client JAR file, and it will use the default location.
In the Target runtime drop-down list, select the application server that you want to target for your development. This selection affects the run time settings by modifying the class path entries for the project.
If you want to add the new module to an enterprise application project, select the Add project to an EAR check box and then select an existing enterprise application project from the list or create a new one by clicking New.
Note: If you type a new enterprise application project name, the enterprise application project will be created in the default location with the lowest compatible J2EE version based on the version of the project being created. If you want to specify a different version or a different location for the enterprise application, you must use the New Enterprise Application Project wizard.
Click Finish to import the application client JAR file.
Just a comment on importing jars into Eclipse (plug-in development) projects:
In case you are developing Eclipse plug-ins, it makes sense to use Eclipse's native bundling mechanism instead of just importing the jar into a plug-in project. Eclipse (or better its underlying OSGi runtime, Equinox) uses so-called bundles which contain some more information than plain jars (e.g., version infos, dependencies to other bundles, exported packages; see the MANIFEST.MF file). Because of this information, OSGi bundles can be dynamically loaded/unloaded and there is automatic dependency resolution available in an OSGi/Eclipse runtime. Hence, using OSGi bundles instead of plain jars (contained inside another OSGi bundle) has some advantages.
(BTW: Eclipse plug-ins are the same thing as OSGi bundles.)
There is a good chance that somebody already bundled a certain (3rd party) library as an OSGi bundle. You might want to take a look at the following bundle repositories:
http://www.springsource.com/repository/app/
http://download.eclipse.org/tools/orbit/downloads/
http://www.osgi.org/Repository/HomePage
Eclipse -> Preferences -> Java -> Build Path -> User Libraries -> New(Name it) -> Add external Jars
(I recommend dragging your new libraries into the eclipse folder before any of these steps to keep everything together, that way if you reinstall Eclipse or your OS you won't have to rwlink anything except the JDK) Now select the jar files you want. Click OK.
Right click on your project and choose Build Path -> Add Library
FYI just code and then right click and Source->Organize Imports
Jar File in the system path is:
C:\oraclexe\app\oracle\product\10.2.0\server\jdbc\lib\ojdbc14.jar
ojdbc14.jar(it's jar file)
To import jar file in your Eclipse IDE, follow the steps given below.
Right-click on your project
Select Build Path
Click on Configure Build Path
Click on Libraries, select Modulepath and select Add External JARs
Select the jar file from the required folder
Click and Apply and Ok
first of all you will go to your project what you are created
and next right click in your mouse and select properties in the bottom
and select build in path in the left corner and add external jar file add click apply .that's it
In eclipse I included a compressed jar file i.e. zip file. Eclipse allowed me to add this zip file as an external jar but when I tried to access the classes in the jar they weren't showing up.
After a lot of trial and error I found that using a zip format doesn't work. When I added a jar file then it worked for me.
Right Click on the Project.
Click on Build Path.
Click On Configure Build Path.
Under Libraries, Click on Add Jar or Add External Jar.
If you are having a trouble on udemy course of chad on springboot for the importing the jar. Then follow these steps.
Right click on the project.
You will see a option of Build Path, click on it.
You will have a option of Configure Build path, click on it.
Go to libraries.
Then go to the place where you have a jar files make them into a new folder and upload on a new place.
Then click on Add External Jars, you will surely be able to upload it which will help on classpathxmlapplicationcontext as well.
Thank you.
I have been developing in NetBeans, I am exploring changing over to eclipse.
We have a set of directories for the modules in our project; we have scripts that check things out of Subversion and do other things with that directory tree, and we have NetBeans access the sources, etc., from that directory tree.
All our modules are built, etc., with Maven. All of this works fine from within NetBeans.
I have successfully imported all the projects into eclipse (File / Import / Maven), but evidently something is different in the handling of "generated sources". We have some castor-generated files in one module, and jaxb-generated files in another. The generated files in both cases are not found by the compiler, and therefore these modules have compile errors.
Maven is configured to generate the Java classes which cannot be found; maven clean deletes them and maven compiler:compile puts them back. But in eclipse those java files cannot be found for compiling other classes, but in NetBeans they can.
I tried deleting the generated java files, then rebuilding in eclipse; the java files were regenerated in generated-sources, but still cannot be found by the compiler when it comes time to compile (or syntax-highlight) my code.
It sort of looks like a classpath issue, but we don't set the classpath in NetBeans for a maven project. How should I configure things in eclipse so the generated class files are found?
In Eclipse in the Package Explorer right click the project folder which contains the missing files. Goto "Build Path >" then "Configure Build Path...". Properties for your project folder will open.
Click on the "Source" tab. Then click on the "Add Folder..." on the left. A source folder selector box opens, here select your folder which contains the auto generated sources. Normally it will be in the target directory. Then press ok. If this will not work, try one directory deeper or less deep.
If there is no target directory, build the project folder with maven on a shell.
The generated-sources directory will be stored in the .classpath file in your project folder.
HTH.
I'm learning Hadoop under VMware now.(win7, 64) Due to some reason, I can't convert a .java file to .jar file under virtual machine, so I tried to create .jar file under Eclipse.
I'm currently using Eclipse MARS(4.5.1). I need to download something about fat jar, but I can't find it online.
My colleague copied his Eclipse software to me. It is already installed, so I copied the whole package. It is Eclipse Kepler. So I am running two Eclipse software on my computer now. will this cause some problem? (I saved projects seperately)
I can do the convert .jar file thing correctly on Eclipse Kepler now. But I still want to use MARS and delete the extra Eclipse.
thank you !
What you're looking for is the "Fat JAR" eclipse plugin.
Fat jar is a jar which contains all the classes used by the project including their referenced dependencies.
The plugin can enable the creation of such a jar.
In your case, however, Eclipse "Mars" & Eclipse "Kepler" include this functionality. The trick is to get to it...
Here's what you do in order to export a Fat JAR:
Right-click on the required Project and select "Export..." --> "Runnable JAR file".
Select the option which extracts libraries and specify the destination JAR file.
Launch configuration is used to execute this JAR with a predefined "Main" class (this is the "Runnable" part...) using "java -jar file.jar".
If you don't plan to - it won't matter.
(Optional) You can also "Save as ANT script" which, well..., generates XML ant script as well.
select project
select Export
Expand the Java node and select JAR file. Click Next
In the JAR File Specification page, select the resources that you want to export in the Select the resources to export field
.
Select the appropriate checkbox to specify whether you want to Export generated class files and resources or Export Java source
or go to http://www.codejava.net/ides/eclipse/how-to-create-jar-file-in-eclipse
As you might notice, I'm quite new to netbeans and programming in general.
I've been working on a small project (homework) and now I need the .java files from one of the packages. When I build the project, i get a .jar archive with all the classes. When I compile the package I need, I get a .jar archive of the .class files of this package (in the "build" folder of the project). However, I need a zip archive of the .java files of this package. I'm a little embarassed to ask, but where do I get these from?
Thanks,
Zhao Nan
From the Projects window (Window-->Projects) or Ctri-1
Navigate to the .java file you want, and right-click on it, and select Properties. The path to the file is shown under All Files.
To see the path to the project right-click on the name of the project (in the Projects window), select Properties, and the project folder is shown under Sources-->Project Folder
If your are on windows, usually if you let netbeans create all by it self it creates a directory called
NetbeansProjects
Under "documents"
There will be a folder list of all your projects. Under the project name that interest you, go in the "src" folder. All your java files should be there.
On Ubuntu 16.04 using NetBeans IDE 8.2, a folder called NetBeansProjects was created in my root directory, parallel to the netbeans-8.2 directory. I'm guessing that this was suggested at installation time and can be configured differently.
