I can launch a JNLP file from Cygwin but not MS-DOS on the same machine. I am using javaws and getting the error to the effect that javaw.exe not found. I read http://javatechniques.com/blog/launching-java-webstart-from-the-command-line/. that one can use java compiler to do the launch So I tried that as well that looks something like this:
c:\Program Files\Java\jdk1.8.0_60\jre\bin>java -classpath
"C:\Program Files\Java\jdk1.8.0_60\jre\lib\javaws.jar;
C:\Program Files\Java\jdk1.8.0_60\jre\lib\deploy.jar"
-Djnlpx.home="C:Program Files\Java\jdk1.8.0_60/jre/bin"
-Djnlpx.jvm="C:\Program Files\Java\jdk1.8.0_60\jre\bin\javaw.exe"
-Djnlpx.remove=true
-Djnlpx.splashport=-1
com.sun.javaws.Main c:\tmp2\new_3.jnlp
And when I do that I get this error:
Error: A JNI error has occurred, please check your installation and try again Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/deploy/util/DeploySysRun

I installed IntelliJ and Java SDK, updated my environment variables, and in "Edit Configurations" the correct JDK is listed under "Build and Run". And I still keep getting a JNI error. None of the other answers have worked so far, I'm completely stuck. Spark is installed at C:\Spark\spark-3.0.3-bin-hadoop2.7 (environment variables have been update). In misc.xml I have:
<component name="ProjectRootManager" version="2" languageLevel="JDK_1_8" default="true" project-jdk-name="1.8" project-jdk-type="JavaSDK" />
The full error is below. Why does this keep happening?
