Hi,

I am trying to compile a .java file (TransformRTDE.java) that uses several import statements. These statements import .class files present in five external JAR files: dataextract.jar, jna.jar, JRI.jar, JRIEngine.jar and REngine.jar. I have read documentation on how to deal with these import statements while trying to compile your .java file from the command line. However, I do not seem to succeed.

I set up the directory in the command line to be the folder in which my .java file resides. In that same folder, I have put the JAR files. When I try to compile the code using java -cp dataextract.jar:jna.jar:JRI.jar:JRIEngine.jar:REngine.jar TransformRTDE.java, I get a package does not exist error. I have set up the class path to include the folder in which all my .java and .jar files reside.

I have searched for hours on this without success. Any ideas what I'm doing wrong?

Thanks in advance!

On Windows you need to use semi-colons instead of colons to separate classpath entries.

Indeed, it's surprising how many wrong answers there are for this question. Thank you, issue resolved.
 
It is sorta covered in the JavaRanch Style Guide.
