My eclipse project structure is as given below
->MyProject
-->JRE System Lib
-->plugin dependencies
-->src
-->extJars (contains some external JARs)
-->icons(contains icons files)
-->META-INF
-->build.properties
-->plugin.xml
-->Myproject.product
When I export MyProject as a product using Eclipse MyProject.product, complete files in MyProject including ExtJars and icons get bundled as a single JAR file.
MyProject/plugins/MyProject_1.0.0.0.jar
I want extJars and icons to be kept outside that single JAR file.
Kindly help me in achieving this.
Thank You
If you use 'features' to build your product you can use the 'unpack the plug-in archive after the installation' option in the 'feature.xml' to have the plug-in expanded when it is installed.

I have always developed my java NetBeans projects. When I finish my project, and automatically build "dist" folder where the main jar and a "lib" folder containing all the external jar was created. This is done automatically with the NetBeans IDE
Now I'm trying to do a project with jdeveloper 12c Java Desktop Application and try to deploy my project but I have problems with java.lang.NoClassDefFoundError. I meet several questions:
Can you add the same structure as I said before? That is, a file jar and inside a folder "lib" place the jars using How to do it?
I've seen examples that by New File Group adds refencias, but it really adds to the main jar file (as I see in the size of the file) but not saved in a separate folder.
I do not know if you can help me do this in jdeveloper 12c: Generate a jar file and folder lib with references.
Thank you for your help.
Go into the deployment profile for your project and add all the libraries and files that you need to be included to the JAR you are generating.
What is the right way to include an additional JAR file in an Eclipse plugin? My own plugin requires apache-commons-io. I copied the JAR into my plugins directory and added it via the "Dependencies" tab of the plugin manifest. This works for me, but other users of my plugins will have to download Commons-IO manually.
What is the correct way to package Commons-IO in my plugin?
I usually use the following strategy:
If I can find the JAR in question packaged as a bundle - i.e. the MANIFEST.MF contains the correct entries - then I use this. Have a look at the Orbit project for a set of pre-packaged bundles of all sorts. org.apache.commons.io is already here...
If that is not possible, then I just include the JAR in my bundle, and updates MANIFEST.MF - e.g. Bundle-ClassPath: library.jar,.
Sometimes it is cleaner to create a unique plugin for libraries.
(So you can use it from several plugins, License topics, Size of your Plug-In, different version, ...)
Do so by "New ..."
Category: "Plug-In Development"
then "Plug-In from existing jar archieve"
Select your jars and there you go.
I try to build a Eclipse plugin that has to use a self written jar which is dependent on other jars, but I don't get the point where to start with handling jars as seperate PlugIns. Anywhere I have to use just the .jar files or am I wrong?
I think I found a proper solution; the trick is that you have to implement all the files via Eclipse. I just copy here the solution which was posted to news.eclipse.platform:
Include the jars in a plugin:
Use Import > File System to import the jar files into your plugin project, say in the <project>/lib directory.
Use Add... button to add the jars to the classpath section of the plugin.xml > Runtime tab.
Use New... button to add "." library back (with no quotes, of course).
Make sure your binary build exports the new jar files on the plugin.xml > Build tab.
Save
On the project, use context menu > PDE Tools > Update Classpath to correctly add the jars to the eclipse project classpath.
What is a self-written jar?
Normally you turn 3rd party jars into bundles using an OSGi MANIFEST.MF (See New>Plug-in Development>Plug-in from Existing JAR archive) or you include them in your plugin.jar and add extra Bundle-ClassPath entries as mentioned by TomaC.
If you mean at runtime your plugin will create a new jar and needs to load it, that's different, though.
Project Properties -> Java Build Path -> Add External jars. Is this what you are looking for?
I'm using Netbeans IDE for developing a web applications, and I've some JARs available in the application server which don't need to be in the WAR (but we need them to compile and run locally).
Is there an option in Netbeans to exclude the JAR file while building the WAR file?
Select the project in the Projects explorer window.
Pick the Project Properties item from the File menu (up in the menubar).
Select the word Libraries from the list on the lefthand side of the dialog that appears.
For each jar/library listed in the Compile-time Libraries list, uncheck those that do not need to be included in your war file.
I found the problem myself. I've all the libraries under my lib folder and added them to the project class path. Since the build is copying the entire content in the project, my library is also copying even though I've unchecked the package check box against the library.
So, don't put the library in your lib folder if you want to exclude that in the WAR built.

i have successfully configured sphinx4 with eclipse.
for that these steps i have used.
copy my java and config files to SRC folder
all the necessary jar files (in the lib). the lib folder added to the root of the project
build those jar files (jsapi files too)
change the configuration file and give the proper path
test the java file
but in Netbeans i really dont understand how to do the proper steps. can someone help me. the jar files should be added to "Libraries" rite.
then after adding them how to build them.
in the netbeans it dont show a SRC folder. so all the java files and configuration files should go to Source Packages folder rite.
can someone help me with this. please
If you have sphinx4-1.0beta6 then you can just open the folder up as a netbeans project. Open netbeans, click open project, then navigate to the sphinx folder and open it. It is already a netbeans project file type as of this version. I assume this will work in later versions also. I have no clue why sphinx doesn't say this on their website.
Sphinx4 is a Java library available in OSS repository, so you can use it as any library.
If your project uses maven/gradle, add repository in your project configuration, then add dependency on two packages - sphinx4 core and sphinx4-data. The former is the main library, the latter is required if you want to recognize US English. Then just start writing the code.
If you want to rely on jar files, just download sphinx4-core and sphinx4-data files from the repository and add them as dependency to the project, then start writing code.
If you want to modify or develop sphinx4 itself, install Gradle support in your IDE, then import latest sphinx4 sources as a Gradle project.

click on Add JAR/Folder
select jar file you want to add
