I am using Eclipse IDE for writing my codes. I have added jar files using POM.xml file. Everything was installed correctly but all the jar files are not stored in Referenced Library folder they are stored under JRE System Library.
Can some one please help me in moving them on to Referenced Library Folder.

First of all, new to Java / Eclipse IDE, so please bear with me.
So, I have created my own project, and I have an external library (class files contained in jar files) in a "lib" folder of my project/workspace. I have created build path, and have the external library source code implemented as well. So, under Referenced library, I have editable .java files for the external library.
Implementation of the external library seems to have worked, as I do not get any "noclassfound" exceptions etc. However, it does not seem as changes I make to the referenced library source code has any effect.
My project is an OpenHab project, where I have a pom file which I run "mvn install. The resulting jar file is used for OpenHab installation. My classpath file has reference to lib files and source code.
Any idea why my source code changes will not take effect?
I have a NetBeans project that uses the GSON library. I've tried including the GSON.jar file without requiring future users to separately download it. However it doesn't seem to work. The project looks for the file from the relative path of my computer so the file isn't found on another user's computer. Is there a way to include GSON.jar and "Export to Zip" and keep the reference in the project itself? I'm lost!
Thank you
Exporting a Project to ZIP zips up the project folder only, and not anything outside of the folder, including dependencies. If you include the GSON.jar file in the project folder, then the JAR file will be included in the .ZIP file. It's a good practice anyway since NetBeans will use a relative classpath and thus if you move the project itself NetBeans won't give you an error message when loading the project.
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.
I created an Eclipse project and I need to use the Super CSV library with Dozer. I downloaded the Super CSV and created a new folder "super-csv" in /usr/lib.
Now I have: /usr/lib/super-csv/super-csv that contains the super csv jar (+ javadoc and source),
/usr/lib/super-csv/super-csv-dozer that contains the super csv dozer jar, javadoc and source plus a "lib" folder.
Inside /usr/lib/super-csv/super-csv-dozer/lib there are many .jar files that are needed for super-csv-dozer to work, so I added it as native library for super-csv-dozer entry in library tab of java build path in Eclipse.
When I try to compile the project, I receive a java.lang.ClassNotFoundException pointing a class that is contained in one of the jar files in the lib folder.
Everything works only if I manually add every jar in lib folder as an external jar.
Can someone explain me where I am doing wrong?
I'd recommend using Maven - it's a widely used tool for Java builds. To start using Super CSV, it would be as simple as adding the 2 dependencies (listed on the Super CSV website), and your Eclipse project would be ready to go.
There's a bit of a learning curve though, so if you want to just add the jars to Eclipse's build path manually, I'd recommend creating a lib directory at the root of your project and putting all of the jars there.
my-project
|-src
| |- (your source in here)
|
|-lib
|-commons-beanutils-1.8.3.jar
|-commons-lang-2.5.jar
|-commons-logging-1.1.1.jar
|-dozer-5.3.2.jar
|-slf4j-api-1.7.1.jar
|-super-csv-2.0.1.jar
|-super-csv-dozer-2.0.1.jar
You can then add them to the build path (here's a good guide).
Just a note: if you're not using the Dozer extension, then you'll only need super-csv-2.0.1.jar on the build path.
i have a project in eclipse that i work with SVN.
i need to upload a jar file to "referenced libraries" yet all i managed to do is uploading it to the main directory.
for some reason the file was uploaded to the main server directory instead of to referenced libraries which there it stayed local. i built the file path correctly i think. in the first place the JAR file was only on the referenced libraries.
how can i fix it?
thx
Try using TortoiseSVN. It will show you where you placed the jar and you can make adjustments accordingly.
I usually put the .jar that need to be referenced libraries in a lib directory under the project main directory. This way, when I checkin the project into SVN, the lib directory gets there as well.
