ada->java bytecode compilation errors

ada->java bytecode compilation errors

[Frenk]

Hi everybody!
I need to compile an ada program to java bytecode, but i have some problems:
- i installed in a windows (xp) system jgnatmake (version 1.1)
- i set the PATH and CLASSPATH environment variables.
Now when i compile as program everything works fine, it generates a .class
program that run correctly with the jvm.
But i need it to be an applet. so i compile as an applet, i build and here i
get the errors.

The errors i get (in AdaGIDE):
---------------------
compiling....
completed successfully
---------------------
building...
jgnatmake -gnatwu -v -gnato -.................
jgnatbind -a0./ -a0D:\.......................
jgnatlink hello.ali
jgnatbind -n -ID:\............
jgnatlink hello.ali
Unable to create jar file--hello$typ.class is missing.
Perhapse this is not an applet?
Done--error detected.
-------------------

So i tried by command line, here the results: (i found the commands in the
documentation)
-------------------
jgnatmake hello
   jgnatbind -x hello.ali
   jgnatlink hello.ali
jgnatbind -n hello.ali
jgnatlink hello.ali
jarmake -o hello.jar hello$typ.class
  jarmake: Cannot find: hello$typ.class
------------------

Maybe the error i do is something obvious, but i'm not so advanced in ada
nor java programming....
If someone can help me, Thanks!!!!

                      Regards!     Frenk

What did you mean when you say "compile as an applet"?  Does that mean
you changed the source code to include something like:

with Java.Applet.Applet;

...

type Typ is new Java.Applet.Applet.Typ with ....


Your program has to be changed such that it inherits a bunch of "applet
making stuff" from the Java-API before it knows how to behave in a
browser (or appletviewer.)

You need to study the examples which are applets, (hello is not).

Hope this helps.
