How to add jar files of GWT in Eclipse luna?
Its ping me frequently for keeping update of plugins? what's the future scope of GWT?
Please guide me for the same.
Credit to #cfulton. Here I got success.
Create lib folder at same level as src folder.
Copy jar into lib folder.
Open up eclipse, or if you already have open refresh by going File->Refresh.
Ensure you can now see your jar file under Project->Lib.
Add library to build.xml file (create pathelement entry in <path id="extras"> section <pathelement location="lib/gwt-bootstrap.jar"/>
Add library to Build Path.
Right Click on project in Package Explorer, Build Path->Configure Build Path.
Click “Add JARs” in the “Libraries” section.
Navigate to the lib folder of your project and select the jar and click okay.
Click okay on the configure build path dialog.
Add <inherits> tag.
In file Component .gwt.xml add the following line (specific to what you are including). <inherits name="com.github.gwtbootstrap.Bootstrap"/>

I'd like to know how to add JAR file to Eclipse 2018-09 project. I've already copied it to lib project's folder. I've tried right clicking on jar file and build path but no actions are displayed.
Thanks in advance
If you are developing a Java Project you want to right click on the project go to properties, click on Java Build Path in the preference tree then on that tab click libraries and on there click add jar and then select the jar you want to add to your classpath.
If you are building a eclipse plugin, open the MANIFEST.MF file go to the runtime tab in the editor and on the bottom right there is a classpath selection, click add and point to the jar you want to add to your classpath.
I have a simple project that I need to be very easily imported into eclipse and started. When I export my project and import it again it comes with an error saying it is missing a required jar file. This jar file is added to the build path, but does not carry over when the project is exported. Why is this? I have been searching all day for an answer on Google and none have helped.
Would I just have to send the jar file along with the project and have the users manually add it?
Things I have tried:
Going into build path order and export and clicking the jar file.
using a clean workspace for the import / restarting eclipse.
For anyone with a future problem like this one. I was putting the jar in the lib folder and also adding it to my build path, but the jar would not export over. When I added the jar to the WEB-INF / lib folder it successfully carried over with the export.
You may want to try this:
Right click on the imported project select Build Path -> Configure Build Path -> Java build Path -> Libraries Tab and check if the jar file which eclipse says missing is present in the Libraries tab.
If it is present then select it and click Edit, a "File dialog" will pop up, find the desired jar which is in your computer's directory. and click Ok then wait for eclipse to build
the workspace. If it is not present then add it through Add JARs... or Add External JARs...
Export it as an Archive file of the project rather than a jar. Then it's just a matter of someone else importing it as an Existing Project. Exporting it as a jar is only something you do when you want to deploy the jar and run it.
I am running Eclipse 3.7. I am currently working on a Plug-In Project for a Application called Team Center. I was recently made aware of a jar file of SWT Widgets named Opal. So I am trying to figure out how to add the Jar File to my existing project. I have tried many different ways to do this. Nothing has worked so far.
Here are some of the things I have tried.
Made a lib directory in my current project copied the jar file
Build Path Configure -> Libraries -> Added the Jar
Runtime tab -> Add -> selected the lib/jar file -> update build path
Saved
My project still compiles, but at runtime it fails and I get can't load proxied handler errors
I have tried to create a plugin project just for the Jar File, then add the opal plugin to required Plug-ins. If the Opal project is closed, that reflects with the Opal plugin in my project.
Here is the way my current project works. It is a plug-in project and when I finish or change code.
Build Project
Export
Deployable plug-ins and fragments
Select my project plug-in
Finish
Then I copy the project.jar to the TeamCenter Application plug-ins directory
I am assuming that somehow I have to include the opal.jar in the project.jar. But right now I am at a total lost on how to do it.
In Eclipse Plugin Project click on your MANIFEST.MF file and go to the runtime tab. There should be a section "Classpath". Try to add your lib there.
UPDATE
I've tried it and it has worked for me. I've executed following steps:
create new Plug-In project
create new lib folder in it
copy opal lib to the folder
open the MANIFEST.MF, go to the Runtime tab and add the lib to the Classpath section
check whether the lib folder is recognized of the build process (Build tab and lib folder should be checked)
Create new Run Configuration (Run -> Run Configuration... -> double click on OSGi Framework)
on Bundles tab check the new made project (Workspace section) and uncheck Target Platform for now
mark the new project and click on the button Add Required Bundles on the right side
now some needed bundles to run your project should be checked in the Target Platform section
click Apply, then Run and your OSGi env will be started
check build.properties in your plugin. check lib folder should be included there.
open plugin.xml or MANIFEST.MF in editor, you see build Tab. In the binary build, make sure your lib folder is checked.
Well I have my source code that i have done using the IDE netbeans. Now I wanted to move this java application to a web application. For that I need to create a jar file from my source code, so that I could invoke it in ma jsp file.
I have not been able to find any option in netbeans or any other way to create a .jar file of this source code.
Could someone tell me how to do that.
Thanks
Create a Java archive (.jar) file using NetBeans as follows:
Right-click on the Project name
Select Properties
Click Packaging
Check Build JAR after Compiling
Check Compress JAR File
Click OK to accept changes
Right-click on a Project name
Select Build or Clean and Build
Clean and Build will first delete build artifacts (such as .class files), whereas Build will retain any existing .class files, creating new versions necessary. To elucidate, imagine a project with two classes, A and B.
When built the first time, the IDE creates A.class and B.class. Now you delete B.java but don't clear out B.class. Executing Build should leave B.class in the build directory, and bundle it into the JAR. Selecting Clean and Build will delete B.class. Since B.java was deleted, no longer will B.class be bundled.
The JAR file is built. To view it inside NetBeans:
Click the Files tab
Expand Project name >> dist
Ensure files aren't being excluded when building the JAR file.
Please do right click on the project and go to properties.
Then go to Build and Packaging.
You can see the JAR file location that is produced by defualt setting of netbean in the dist directory.
I also tried to make an executable jar file that I could run with the following command:
java -jar <jarfile>
After some searching I found the following link:
Packaging and Deploying Desktop Java Applications
I set the project's main class:
Right-click the project's node and choose Properties
Select the Run panel and enter the main class in the Main Class field
Click OK to close the Project Properties dialog box
Clean and build project
Then in the fodler dist the newly created jar should be executable with the command I mentioned above.
Now (2020) NetBeans 11 does it automatically with the "Build" command (right click on the project's name and choose "Build")
I just recently downloaded the dom4j library, but for the life of me I have no idea how to access it. I dropped it in the plug-ins folder and rebooted Eclipse, without success. For some reason finding a straight answer for this is more difficult that I thought it would be.
No, don't do it that way.
From your Eclipse workspace, right click your project on the left pane -> Properties -> Java Build Path -> Add Jars -> add your jars here.
Tadaa!! :)
Extract the jar, and put it somewhere in your Java project (usually under a "lib" subdirectory).
Right click the project, open its preferences, go for Java build path, and then the Libraries tab. You can add the library there with "add a jar".
If your jar is not open source, you may want to store it elsewhere and connect to it as an external jar.
For the Android library projects, I do it as in the attached screenshot:
Right click the project, select Properties->Android and in the library section click Add. From here you can select the available libraries.
If you are importing a jar file, then importing them as jar or external jar, as other posters posted would work. I prefer to copy/paste jar file in the libs folder (create one if it doesn't exist) and then import as jar.
If you want to get this library into your library and use it, follow these steps:
You can create a new folder within Eclipse by right-clicking on your project, and selecting New Folder. The library folder is traditionally called lib.
Drag and drop your jar folder into the new lib folder, and when prompted select Copy Files.
Selecting the Project tab at the top of the screen, and click Properties.
Select Java Build Path followed by the Libraries tab.
Click the Add JARs… button and select your JAR file from within the lib folder.
Your JAR file will now appear in both the lib and Referenced Libraries folders. You can explore the JAR's resources by clicking Referenced Libraries.
