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.

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'm trying to use an external library contained in a .jar file with the Play Framework.
I've added the .jar file to the lib/ directory, to no avail.
I know I could add the dependency to my project/Build.scala file, but I have no idea what the group ID, artifact ID, or version numbers are. Are those found in the .jar file?
You can go to Project Structure
Under Project Setting -> Modules ->
Go to tab Dependencies , under sbt-unmanaged-jars you can edit and add your lib manually.
groupID, artifactID and version are “Maven Coordinates”. These three identifies are needed to find exact jar file in the Maven Repository. When provided, the build system (and Play! uses SBT) can automatically find, download and include the library you want to use (assuming that that library exists in the repository).
As that is a global repository, groupID should uniquely identify the project. groupID is usually the same as the main project's package, e.g. org.apache.commons. artifactID is supposed to identify a particular jar in the project, e.g. commons-io. version, quite obviously, points to the exact version of the jar.
How to use IntelliJ with Play Framework and Scala
see this short tutorial.
but you have to add all necessary jars to lib folder before call create module command idea with-sources=yes
So, again
Create a new application
Create lib folder and copy all jars
Create the IDE module
This is only one way how I can deploy it successfully
My environment:
Netbean 6.9.1
Glassfish 3.0.1
Windows 7
Goal:
When my coworkers opens the Netbean Project, the library is already referenced without them manually create library, adding jars into it and reference it.
Detail:
I created Netbean project and the project has reference to few jar files in the folder.
Currently whoever opens the project for the first time, they have to manually create library and refer it to the project.
My project location:
C:\Users\masatosan\Desktop\myProject\myApp
My library location:
C:\Users\masatosan\Desktop\myProject\lib\myLib
The myLib folder contains:
some1.jar
some2.jar
some3.jar
I can achieve my goal if I create reference to individual jar file by defining to project.properties file like below: (creating reference to sqljdbc4.jar)
file.reference.sqljdbc4.jar=../lib/sqljdbc4.jar
javac.classpath=\
${libs.restlib_gfv3ee6.classpath}:\
${file.reference.sqljdbc4.jar}:
But my case is different since I have 3 jars in the myLib folder and wanting to reference them all.
Is it possible to reference all jars in myLib folder?
Please let me know if you need more clarification.
I'm sorry, but it doesn't work that way. When you create a project, you have to add the jar files individually.
However, if you put your lib folder under your project, netbeans will refer to them via relative paths. Then when you share the project (lib directory included), netbeans will be able to automatically find the jar files when the next person uses the project. That way you only have to add jar files once.
Short of using a dependency management tool like maven (which Netbeans has good support for), this is really the best solution. It uses a bit more disk space (obviously), but that's never been a huge issue for me.
I figured how so let me share.
Tool --> Library then library window pop up.
Create library called "MyLib" which contains multiple jars.
Add "MyLib" to your project. This change will be written to project.properties file under nbproject folder.
project.properties file indicates the classpath of lib reference you just added.
It should look like something below
javac.classpath=\
${libs.Excella.classpath}:\
${libs.MyLib.classpath}
Now someone else opens the project from different machine and she just needs to do step#1 and #2, which is to create library with same library name i.e. "MyLib"
I think this is what Bill was saying originally but thought it would be helpful to give step by step instructions since I finally figured .... after long time :D
