I am thinking that Erno is on the right track, or there is something
wrong with the jar.

Here is a simple test to see that all you need is to add the jar through
the Properties panel, then add include and import statements.

Download the jars from http://freetts.sourceforge.net/docs/index.php and
add the jar via the Java panel of the Properties dialog box.

put this code in your main rb

include Java
import com.sun.speech.freetts.Voice
import com.sun.speech.freetts.VoiceManager

voice = VoiceManager.getInstance.getVoice('kevin16')
voice.allocate

# Speak the text
voice.speak("title")
voice.speak("body")

No changes, sorry.

I had th error:

: cannot link Java class draft.Person (NameError)


So as I wrote this error might be caused by using a different version
of Java for running than with which the class was compiled. Please add
the "-w" switch to Ruby options in Project properties -> Run and post
the whole stack trace then.

Thanks,
Erno

Hi Chris and Erno !

I tried the freets project. It works even if the source code was built with
jdk 1.4. and I had jdk 1.6 installed (that was neccesary for use the last
JRuby importation syntax). But my simple calss Person does not work!

My person_loader.rb is like that:

include Java
import draft.Person

person = Person.new
puts "person: #{person}"

And I got "D:\Netbeans projects\myJruby\lib\person_loader.rb:2: undefined
local variable or method `draft' for main:Object (NameError)"

I attached the zip containing my java project built in Eclipse 3.3.2 (really
very small..). May be t will help you to detect the reason of my errors. To
resume I use:
- jdk/jre (for Eclipse) 1.6.0_06.
- JRuby 1.1.2

%JAVA_HOME% point to the above jdk.
System variable path has: %JAVA_HOME%\bin;C:\jruby-1.1.2\bin; etc.
Thank you in advance.

I should have been more specific about the problems with different
versions of Java - classed compiled with an older version will work
under a newer version. Your thirdparty.jar was compiled with 1.6 and
doesn't work under 1.5 or older.

You need to use quotes here, i.e. import 'draft.Person'.

Quote:
person = Person.new
puts "person: #{person}"

And I got "D:\Netbeans projects\myJruby\lib\person_loader.rb:2: undefined
local variable or method `draft' for main:Object (NameError)"

See above - please try again with quotes.

So probably you're running it under JDK 1.5. Please try the following
step by step instructions and let us know the result:

First, open the windows console and:

1. check that you are using JDK 1.6 - type "java -version" in the console
2. check that you are using JRuby 1.1.2 - type "jruby --version"
3. create a new file called person_loader.rb and paste the following
there (assumes that you still have the jar in the same location):

include Java
require 'D:/Netbeans projects/myJruby/jars/thirdparty.jar'
import 'draft.Person'

p = Person.new
puts p


4. run the file - type "jruby -w person_loader.rb" (of course, you need
to be in the same directory where the person_loader.rb is located).
5. if that does not work, post the error here with the output from steps
1) and 2)


Thanks,
Erno

I did everything as you told me. The below are the results:

C:\Documents and Settings\be327538>java -version
java version "1.6.0_06"
Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
Java HotSpot(TM) Client VM (build 10.0-b22, mixed mode, sharing)

C:\Documents and Settings\be327538>jruby -v
ruby 1.8.6 (2008-05-28 rev 6586) [x86-jruby1.1.2]

D:\Netbeans projects\myJruby\lib>jruby -w person_loader.rb
Unknown name
So it works!!! But:

If I launch it from the command line (via cmd comand in a DOS window) it
works!!!! BUT if I launch it from Netbeans by changing the run configuration
via 'Project-properties-Run' where i set:
- configuration: even if I create a new one, it will not be shown in the
list of availbale configurations when you right click on the "project-Set
configuration" menu. The only configuration is always default!! So I had to
modifiy the default configuratio by setting the main script as
person_loader.rb, ruby options as -w. And in this case it does not work and
generate an error:

That is not the first time when I see the difference in execution of Ruby or
JRuby scripts via cmd command ad Netbeans interface. Thank you for you help.
But nevertheless I would like to know if it is possible to resolve this
inconvenience of execution.

OK, there is more than one way to solve this, but for example the
following should work:

Please find the netbeans.conf file, which is located in [your netbeans
install dir]\etc\netbeans.conf. Then uncomment the following line

#netbeans_jdkhome="/path/to/jdk"

and make sure that it points to JDK 6 installation, e.g.

netbeans_jdkhome="/path/to/jdk1.6.0_10"

After that restart the IDE and try to run the file again. This should
work since by default JRuby will run with the same JDK as the IDE.
Alternatively you can set the 'jruby.java.home' system property as
described in http://wiki.netbeans.org/FaqHowToCallJavaFromRuby.

HTH,
Erno

YESSSSS !

It was that. I modified the etc/netbeans.conf file because it pointed to jdk
1.5. It's because I had installed Netbeans before installation of jdk1.6.
After that change everything work fine.
And no need to require thet jar, - its adding to the classpath via
Project-Properties-Java was recongnised !
So I deleted the line:

require 'D:/Netbeans projects/myJruby/jars/thirdparty.jar'

THANKS A LOT !!!

Quoting Charles from JRuby ML:

======
The no-quote version only supports four top-level packages: java, javax,
org, and com. This is to prevent infecting the top-level namespace with
too many methods (each of these is a method we use to drill down into
the package). The string version works with anything.

You can still load arbitrary packages like this too:

import Java::mypackage.Foo
