(Not that I have anything against those either). You have to locate the Weka jar and launch from some sort of command line console. Your way works too but is a little more manual.
#Weka jar java how to#
I thought I included information on how to do that compile/jar command line in my post, although I’m not seeing it in the thread now. Recompile it as Java 7 would make it usable as normal. NeuralNetwork was compiled with a later version that included a different major.minor class version causing a version incompatibility error. You would be more likely not to encounter java version problems if you use the same java version as everyone else using the application. I’m not sure what the advantage would be to using a later java version than Weka expects if its not. Weka itself might be compiled as Java 8 now. If you want to use your Java 8, you only have to locate the weka jar file and run the following On Dec 20, 2015, at 7:38 PM, Tarek TURKI wrote: When i looked this issue #2, i tried to see my own java version and I have java 1.8 in my computer, so I don't what'is the matter. usr/bin/weka: Unable to locate libsvm.jar in /usr/share/javaĮxception in thread "main" : weka/gui/GUIChooser : Unsupported major.minor version 52.0Īt 1(Native Method)Īt (ClassLoader.java:800)Īt (SecureClassLoader.java:142)Īt (URLClassLoader.java:449)Īt $100(URLClassLoader.java:71)Īt $1.run(URLClassLoader.java:361)Īt $1.run(URLClassLoader.java:355)Īt (Native Method)Īt (URLClassLoader.java:354)Īt (ClassLoader.java:425)Īt $AppClassLoader.loadClass(Launcher.java:308)Īt (ClassLoader.java:358)Īt (LauncherHelper.java:482) After installation, that's the error I have when I tried to launch weka: Add the reference and your project should work like a charm.I'm using weka 3.6.10-2.

#Weka jar java archive#
JAR files are archive files that include a Java-specific manifest file. It is a package file format typically used to aggregate many Java class files and associated metadata and resources into one file.

In the CRISP-DM data mining process, machine learning is at the modeling and evaluation stage. This generates the dll file in your current directory. This is the bite-size course to learn Java Programming for Machine Learning and Statistical Learning with the Weka library.Open the command prompt and do the following and press enter:.This lets you use ikvm from command line. In my case, it was “C:\Program Files\ikvm-.5\bin”. Once you have downloaded and installed IKVM, copy the address of bin folder to the path variable.After searching some stuff, i figured out how one can convert a jar file to use it as dll.

I had this weka.jar file which I needed to use in my C# code. I was coding in C# while I had to use Weka which is implemented in Java. Weka is a collection of algorithms implemented for various data mining tasks such as classification, association rule analysis, etc. This was while working on a project when i had to use “Weka”.
