Creating jar file using autotools

[Peter Fodrek]

Dear autotools experts,

I am stranger in builtools like autotols. My practice in Unix based  C and Java
programming  using manually created Makefiles lasts 15 years.

I am able to produce both ELF  binaries (from C source code and java source
using gcj) and class files form java source codes, but I am not able to produce
jar archive form class or java source files.

Would anybody describe me  where are my mistakes,please?
Would anybody describe me  possible solutions, please?

I was unable to find out soultion except
one at URL http://lists.gnu.org/archive/html/automake/2011-07/msg00015.html
that does not work for me.

Thank you for any answer

I look forward hearing form you

Yours faithfully

Peter Fodrek
