Still feels close... just need to get "jar within a jar" working, long classpaths aren't friendly or portable.<br>

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.<br>
<br>
Or you can create an uber jar.<br>
<br>
There should be a way to include a jar in a jar, but it’s non-standard, custom code.<br>
<br>
Or change the classpath, removing the usefulness of a single jar.<br>
<br>
What you’ve got here is kind of a random fix to a non-issue. Did you address my issues with creating output folders?<br>
<br>
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.<br>

<br>
Hi John, getting closer... Have added a new CommandLine class and modified the<br>
<br>
.jar files to handle command-line invocation.<br>
<br>
<a href="http://www.web3d.org/specifications/java/javadoc/org/web3d/x3d/jsail/CommandLine.html" rel="noreferrer" target="_blank">http://www.web3d.org/specifica<wbr>tions/java/javadoc/org/web3d/<wbr>x3d/jsail/CommandLine.html</a><br>
<br>
Latest build is still having trouble with visibility of saxon8he.jar within the<br>
<br>
X3DJSAIL .jar.<br>

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

<br>
==============================<wbr>==============================<wbr>=======<br>
<br>
Note: The Class-Path header points to classes or JAR files on the local network,<br>
<br>
not JAR files within the JAR file or classes accessible over Internet protocols.<br>
<br>
To load classes in JAR files within a JAR file into the class path, you must<br>
<br>
write custom code to load those classes. For example, if MyJar.jar contains<br>
<br>
another JAR file called MyUtils.jar, you cannot use the Class-Path header in<br>
<br>
MyJar.jar's manifest to load classes in MyUtils.jar into the class path.<br>
