[Dart] Ant 'test' junit task failure; junit.jar drop-in doesn't work

[Matt England]

Dan,

Thanks for the email notes/replies.  I like impression I'm getting that 
someone like yourself is championing the support for this product.

Sun's JDK/J2SE (are these the same things? I assume JDK = Java SDK = Java 2 
Standard Edition? there is no "guidebook" on sun.com that I can find) 
doesn't even get off the ground (which is namely why I'm using gcj/jikes on 
Debian, simply out of necessity).  Here's an excerpt from a large session 
description below:

mengland at csbase1:~/svnwork/Dart/trunk$ ant test
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object
mengland at csbase1:~/svnwork/Dart/trunk$

I suspect this error reflects my extreme level of Java ignorance and that 
some path/env-variable/tweak will fix this.

For what it's worth, the jdk path reference below was created by 
downloading the Linux rpm from:

http://javashoplm.sun.com/ECom/docs/Welcome.jsp?StoreId=22&PartDetailId=jdk-1.5.0_06-oth-JPR&SiteId=JSC&TransactionId=noreg

...is found at:

http://java.sun.com/j2se/1.5.0/download.jsp

Is this the right stuff?

<rant>
I've been developing and using cross-platform (Windows, Unix, Linux, VMS, 
BSD) software (that includes low-level storage-interface driver support) in 
C/C++ and a numerous interpreted languages (php, perl, tcl/tk, bash, ksh, 
etc etc) on and off for about 12 years.  I've *never* had as many headaches 
building and porting applications as I do with Java, despite Java being 
trumpted as the Holy Grail of easing porting problems.

My golden rule in software development: eliminate dependencies (and this 
has many contexts beyond the current one).  Java-based systems tend to 
create dependencies all over the place (VMs, classpaths, jars, classes, etc 
etc) that break a lot.  I really don't blame this on the Java developers; I 
blame this on the Java system.  Alternatively, I can statically link and or 
embed dynamically-linked libs in any non-Java app I desire.  And I do in 
software that my projects build.

I'm still waiting for the day when the Java community gets this.

Thanks for allowing me get this off my chest. :)

Now on to a more-productive conversation...

-Matt
