Subject: [rjb-users] Strange error when including another library
Message-ID: <20061101150016.42879.qmail@web34211.mail.mud.yahoo.com>

Hello Again,

I'm using RJB with a C++ toolkit called Open Babel
(http://depth-first.com/articles/2006/10/31/obruby-a-ruby-interface-to-open-babel).
It uses a SWIG wrapper.

When using Open Babel and RJB together I get a strange
error message. This series of commands produces the
error:

require 'rubygems'
require_gem 'rjb'
require 'rjb'
require 'openbabel'

nts = Rjb::import
'uk.ac.cam.ch.wwmm.opsin.NameToStructure'

This is the error that is produced (using irb):

InternalError: unknown exception
        from (irb):6:in `import'
        from (irb):6

However, when I use this sequence of commands, I get
no errors and can go on to use both libraries:

require 'rubygems'
require_gem 'rjb'
require 'rjb'

nts = Rjb::import
'uk.ac.cam.ch.wwmm.opsin.NameToStructure'

require 'openbabel'

If I'm using Rjb::import to import Java library
classes (java.util.Vector), then I don't get errors
regardless of the order of commands. I've checked
CLASSPATH, and it appears unmodified by require
'openbabel'. Also, require 'net/http' in place of
require 'openbabel' does not produce an error
regardless of the order of commands.

Any ideas?

thanks,
Rich

Hi Arton,

The delegation idea is nice. I gave it a try and it
worked. Now I have a more difficult question.

Here's a situation I'd like to get working. I have a
Java library. A class has a static method that takes
an argument of type Foo:

public class Foo
{
  //...

  public void bar()
  {
    //...
  }
}

and....

package my.lib;

public class Util
{
  //...

  public static void doSomething(Foo foo)
  {
    // use F
  }
}

In Ruby, I would like to create a pure Ruby class that
works like the Java class Foo:

class FakeFoo

  #...

  def bar
    #implement
  end
end

I'd like to be able to do this:

require 'rjb'

Util=Rjb::import 'my.lib.Util'

ff=FakeFoo.new

Util.doSomething(ff)

When I try this now, I get a method_missing error. But
what is the method that's missing? What can I do to
FakeFoo to make it work with the Util.doSomething
method?

cheers,
Rich

Hi, Rich,

This is the case what really class inheritance is required.

I suppose that the method_missing error was occured for calling
Util#doSomething(Foo foo), because your FakeFoo is not a subclass of Foo,
so Rjb searched a method Util#doSomething(Object), and then it threw the
exception because the method was missing. 

At this time, the best solution is to define an interface, because Rjb
can bind the interface with Ruby class.
But I know that is useless for the existing methods like
Utli#doSomething(Foo foo).

Hi,

Ummmm, it's difficult, and I have no idea about that. It's really need
to analyze what had happend between Open Babel and uk.ac.cam.ch.... 
Sorry.

Subject: [rjb-users] Can't find jarfile classes with Rails
Message-ID: <835466.42977.qm@web34212.mail.mud.yahoo.com>

I am having problems with RJB importing a class from a
jarfile when using Rails.

The following works fine (on Linux amd64):

(1) Create a directory called 'test', and copy a
jarfile into it (I'm using Junit 'junit-3.8.1.jar',
but any jarfile will do).

(2) export CLASSPATH="./junit-3.8.1.jar"

(3) $ irb
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require_gem 'rjb'
=> true
irb(main):003:0> require 'rjb'
=> true
irb(main):004:0> Rjb::import 'junit.framework.Assert'
=> #<Rjb::Junit_framework_Assert:0x2b1e487c2360>

So far so good.

But loading Rails first and then the JUnit class
fails:

$ irb
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require_gem 'rails'
=> true
irb(main):003:0> require_gem 'rjb'
=> true
irb(main):004:0> require 'rjb'
=> true
irb(main):005:0> Rjb::import 'junit.framework.Assert'
InternalError: unknown exception
        from (irb):5:in `import'
        from (irb):5
irb(main):006:0> Rjb::import 'junit.framework.Assert'
NoClassDefFoundError: junit/framework/Assert
        from (irb):6:in `import'
        from (irb):6
        from :0

Notice how I'm getting two different errors for the
same invocation of Rjb::import.

Does anyone else have the same probelem?

thanks,
Rich

Hi, Rich

I've heard the issue from Ias (CCed with this mail).
But I couldn't reproduce with Ruby 1.8.5, rjb 1.0.2, rails 1.1.6 on
Win32(x86).
By the way, the mailing list is working, I think.

and on Linux (ruby 1.8.5, rjb 1.0.2, rails-1.1.6)

Hi Arton,

Well, at least we've narrowed it down to my platform.
Was the other user's platform also Linux amd64?

$ cat /proc/version
Linux version 2.6.17-5mdv (rtp at ramanujan.mandriva.com)
(gcc version 4.1.1 20060724 (prerelease) (4.1.1-3mdk))
#1 SMP Wed Sep 13 14:28:02 EDT 2006

$ ruby -v
ruby 1.8.5 (2006-08-25) [x86_64-linux-gnu]

$ rails -v
Rails 1.1.6


$ java -version
java version "1.5.0_09"
Java(TM) 2 Runtime Environment, Standard Edition
(build 1.5.0_09-b01)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_09-b01,
mixed mode)

Hi all

I've got some information about that Amd64 version of Rjb is crushed in
java.util.zip.Inflater. And I found Java's rt.jar was not compressed and
junit-4.1.jar was compressed.
So wouldn't you please un-jar and re-jar junit-4.1 or other jars caused
InternalError without compression.

Ias, I apologised you that I've forgotten the Rjb's feature that emits
the stack-trace of Java'e exception if one sets $VERBOSE = true.

Regards.

Hi all

Please reference

http://www.mail-archive.com/java-linux at java.blackdown.org/msg15764.html

The conversation was stopped by fail, but my colleague found setting
LD_PRELOAD is usable in his environment.
So, please test with below.

% export LD_LIBRARY_PATH=/opt/jdk1.5.0_09/jre/lib/amd64/server:/opt/jdk1.5.0_09/jre/lib/amd64
% export LD_PRELOAD=/opt/jdk1.5.0_09/jre/lib/amd64/libzip.so

We may not export LD_PRELOAD because it's temporary solution.
So please test as :
% LD_PRELOAD=/opt/jdk1.5.0_09/jre/lib/amd64/libzip.so irb
% LD_PRELOAD=/opt/jdk1.5.0_09/jre/lib/amd64/libzip.so script/server

Hi Arton,

I tried setting LD_PRELOAD, and it worked! Using the
same setup as in my original posting:

$ export
LD_LIBRARY_PATH=/usr/java/jdk1.5.0_09/jre/lib/amd64:/usr/java/jdk1.5.0_09/jre/lib/amd64/server

$ export
LD_PRELOAD=/usr/java/jdk1.5.0_09/jre/lib/amd64/libzip.so

export CLASSPATH="./junit-3.8.1.jar"

$ irb
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require_gem 'rjb'
=> true
irb(main):003:0> require 'rjb'
=> true
irb(main):004:0> Rjb::import 'junit.framework.Assert'
=> #<Rjb::Junit_framework_Assert:0x2b85d75c23e8>

Many thanks for finding a solution!

Hi All,

I made a mistake in my test code. It should be:

$ irb
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require_gem 'rails'
re=> true
irb(main):003:0> require_gem 'rjb'
=> true
irb(main):004:0> Rjb::import 'junit.framework.Assert'
=> #<Rjb::Junit_framework_Assert:0x2b25d052dac0>

cheers,
Rich

Hi All

I don't know exactly what module was confliting with libzip.so.
But at least rjb's external symbols were very vague. So I've changed the
symbols and just released rjb-1.0.3.
Wouldn't you please test with this version without setting LD_PRELOAD.
If it could work, there's no need to set LD_PRELOAD anymore. But if it
couldn't work unfortunately, another shared object is the cause.
Sorry for inconvenience.

Best regards

I just tested 1.0.3 it as well, and I'm still getting:

$ irb
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require_gem 'rails'
=> true
irb(main):003:0> require_gem 'rjb'
=> true
irb(main):004:0> require 'rjb'
=> true
irb(main):005:0> Rjb::import 'junit.framework.Assert'
InternalError: unknown exception
        from (irb):5:in `import'
        from (irb):5

But when I use LD_PRELOAD, 1.0.3 still works fine:

$
LD_PRELOAD=/usr/java/jdk1.5.0_09/jre/lib/amd64/libzip.so
irb
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require_gem 'rails'
re=> true
irb(main):003:0> require_gem 'rjb'
=> true
irb(main):004:0> require 'rjb'
=> true
irb(main):005:0> Rjb::import 'junit.framework.Assert'
=> #<Rjb::Junit_framework_Assert:0x2af52e8a4460>

Thanks for your testing rjb-1.0.3.
The problem is caused by Sun's implementation of libzip.so, this shared
object exports non-internalized symbols, so dynamic loader (not Java
world, it's just C world) miss resolves the functions in the process.
And at this time, I have no clue and resolution, so please use
LD_PRELOAD carefully.
The reason of update for Rjb-1.0.3 is just changing rjb's external symbols
as internalize with putting prefix, because I'm afraid of the
confliction is triggered by rjb, but unfortunately rjb is not guilty.

Thanks

Subject: [rjb-users] Overloaded Two-Argument Constructors with new_with_sig
Message-ID: <865533.51632.qm@web34215.mail.mud.yahoo.com>

Hi All,

How can I invoke an overloaded two-argument
constructor with new_with_sig?

I'm trying this (not my actual example, but similar):

Foo.new_with_sig('Ljava.lang.String;Ljava.lang.String;',
'hello', 'goodbye')

Is this the correct format?

thanks,
Rich

Yes, this format is correct.
Any problem ?
