Code running in Netbeans but not in command line

Question

I downloaded the time series classification toolbox available here that I succeed to run with Netbeans (not with Eclipse due to compatibility problems) using the command

netbeans --jdkhome /usr/lib/jvm/java-1.8.0-openjdk-amd64/

I would like to be able to run it on a server so I need to be able to run it using command lines. However I didn't succeed. My guess is that there is a problem with jdk (I'm not used to Java so it might be something else), since when I run

sudo update-alternatives --config java

I get

There are 5 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                            Priority   Status
------------------------------------------------------------
  0            /usr/lib/jvm/java-9-openjdk-amd64/bin/java       1091      auto mode
  1            /usr/bin/gij-4.8                                 1048      manual mode
  2            /usr/bin/gij-4.9                                 1049      manual mode
  3            /usr/bin/gij-5                                   1050      manual mode
* 4            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java   1081      manual mode
  5            /usr/lib/jvm/java-9-openjdk-amd64/bin/java       1091      manual mode

Which does not contains the path to the jdk I use with Netbeans. I didn't find a way to tell Java that I wanted to use another jdk, so I tried without:

Example where I run a specific main file

From TimeSeriesClassification/src:

javac timeseriesweka/classifiers/LearnShapelets.java 
java -cp ../bin:. timeseriesweka.classifiers.LearnShapelets

Any help on how to set up correctly Java will be appreciated

With (following the answer of ACV)

java -cp ../bin/Test.jar:lib/*:. timeseriesweka.classifiers.LearnShapelets

Try this:

-cp "../bin/Test.jar:lib/*:." instead of your:

-cp ../bin:.

Got a different error: Exception in thread "main" java.lang.BootstrapMethodError: java.lang.NoClassDefFoundError: java/lang/invoke/StringConcatFactory at timeseriesweka.classifiers.LearnShapelets.main(LearnShapelets.java:746) Caused by: java.lang.NoClassDefFoundError: java/lang/invoke/StringConcatFactory / Caused by: java.lang.ClassNotFoundException: java.lang.invoke.StringConcatFactory (I'll had the full error in the question)

That's a Java 9 class. So you need java 9 to run that: docs.oracle.com/javase/9/docs/api/java/lang/invoke/…

javac -version returns: javac 9-internal whereas java -version returns openjdk version "1.8.0_151" So if I understand well I just need to update my JDK version?

ACV Over a year ago

You need both to be the same java 9
