[x3d-public] X3DJSAIL: command line option to force output directory creation

[John Carlson]

Try using JavaWS (web start) and a .jnlp file.  I am not sure of the status of these as I have not used them since Java 6.

Or you can create an uber jar.

There should be a way to include a jar in a jar, but it’s non-standard, custom code.

Or change the classpath, removing the usefulness of a single jar.

What you’ve got here is kind of  a random fix to a non-issue.   Did you address my issues with creating output folders?

Also, I am not sure what you are doing with the jar url with stylesheets, but I’m going to assume it works for now.

Hi John, getting closer... Have added a new CommandLine class and modified the 
.jar files to handle command-line invocation.

http://www.web3d.org/specifications/java/javadoc/org/web3d/x3d/jsail/CommandLine.html

Latest build is still having trouble with visibility of saxon8he.jar within the 
X3DJSAIL .jar.

$ pwd
$ /cygdrive/c/x3d-code/www.web3d.org/x3d/stylesheets/java/examples
$ java -jar ../jars/X3DJSAIL.3.3.classes.jar 
HelloWorldProgramOutput.Reloaded.x3d -classicVRML
parameter: -classicVRML for conversion to ClassicVRML encoding 
HelloWorldProgramOutput.Reloaded.x3dv
Exception in thread "main" java.lang.NoClassDefFoundError: 
net/sf/saxon/s9api/SaxonApiException

Have found that Class-Path within .jar is not able to handle internal paths. 
Haven't found correct approach yet.  In this case, am trying to provide internal 
visibility to saxon9he.jar which is within X3DJSAIL.3.3.classes.jar

https://docs.oracle.com/javase/tutorial/deployment/jar/downman.html
===================================================================
Note: The Class-Path header points to classes or JAR files on the local network, 
not JAR files within the JAR file or classes accessible over Internet protocols. 
To load classes in JAR files within a JAR file into the class path, you must 
write custom code to load those classes. For example, if MyJar.jar contains 
another JAR file called MyUtils.jar, you cannot use the Class-Path header in 
MyJar.jar's manifest to load classes in MyUtils.jar into the class path.
