AW: [Acdk-developer] Apache Xalan-C++ & Xerces-C++ in Artefaktur

[Roger R. K. <ko...@ar...>]

Hi,

>>
    I would like to ask why the XML in Artefaktur is not based on Apache
Xalan-C++ & Xerces-C++ ? These are most popular Java versions of XML
realizations and all Java programs which use XML very easy will be =
ported to
Artefaktur.
<<
ACDK includes two implementation for the org::xml:sax and org:w3c::dom
interfaces: expat with a lightweight non-validating parser
And libxml2 as validating parser including xpath support.

It is also possible to add more implementation for the org::xml:sax and
org:w3c::dom, like Xalan/Xerces.

There reason, why I preferred to use the Xerces/Xalan implementation:
- Code size and license will not allow to include the Xerces/Xalan
implementation in the acdk distribution.=20
  The current acdk_xml should compile on all platform without any need =
to
download/compile/link external libraries.
- Xerces/Xalan is rather heavy-weight. It provides own String and =
Container
solution and it would be necessary
  to copy these strings and container in memory from/to ACDK and
Xerces/Xalan String/Container versions.
- Xerces-C++ provides its own object C++ hierarchy. It is quite =
difficult to
wrap an existent object hierarchy
  with another. Casting from a base object to a derived object (like =
Node to
Element) will be a quite difficult
  thing. Wrapping an C++ object hierarchy on a (implicit) C hierarchy is =
in
the opposite quite easy.

I don't say it is impossible to use Xerces/Xalan as XML implementation =
and
wrap it with ACDK object model, but
it has several pitfalls.

AW: WG: AW: [Acdk-developer] Compiling problem

[Roger R. K. <ko...@ar...>]

Hi,
>>   I have the following principle question: in case that we would like to
load some class dynamically through class name and in case that this class
is not included in our EXEcutable file because of compilator optimization
how can we load this class?
  << 

First you have to put your classes into a DLL. The name of the DLL has to
reflect the namespace of your classes (like com::company::mylib::MyClass
should reside in
com_company_mylib_d.dll).
Also add metainfo/extended RTTI to your classes using the acdkmc compiler.

After compiling it, put the library into the ACDKHOME/bin path, so that the
classloader
can find the DLL.

Please refer also to:
http://acdk.sourceforge.net/acdk/docs/hb/lang/acdk_hb_mi_nameservice.html

To look, if your classes can be accessed via dynamic loading and invokation
You can also make use of the CfgScript language:
http://acdk.sourceforge.net/acdk/modules/acdk_core/docs/acdk_cfgscript_hb.ht
ml

To access the classes dynamically from C++ you have two possiblities:

Using Weak invokation:
http://acdk.sourceforge.net/acdk/docs/hb/lang/acdk_hb_dmi_basics.html#Dynami
c%20Method%20Invokation%20(DMI)
http://acdk.sourceforge.net/acdk/docs/hb/lang/acdk_hb_dmi_use_cpp.html


The second possibilty to access your classes in a native C++ way is
To use an interface library. 

Therefore you have to split you C++ classes in a interface part 
(http://acdk.sourceforge.net/acdk/docs/hb/lang/acdk_hb_types_interfaces.html
)
and an implementation part. 
The implementation part implements the interfaces.

For both interface and implementation library, generate metainfo with
acdkmc.

The interfaces classes are in one library, which has to be linked to the 
The executable.
The implementation classes are in another library, which can be loaded at
runtime:

MyInterface is an interface known by the executable.
MyClass implements the interface MyInterface, but will loaded at runtime:

RMyInterface iface =
(RMyInterface)Class::forName("com::company::mylib::implementation::MyClass")
.newInstance();
RString s = Iface->callMethod("asdf", 42);

The advantage of this method is, that you can access the methods in a type
safe way.

Hope this helps,
Roger

   Dear Roger,

   Thank you very much for the help.
   I have the following principle question: in case that we would like
to load some class dynamically through class name and in case that
this class is not included in our EXEcutable file because of
compilator optimization how can we load this class?

Hi,

The problem with the code you send:
class ACDK_CORE_PUBLIC NewObjects : extends acdk::lang::Object=20

The macro ACDK_CORE_PUBLIC is reserved to acdk_core library to export =
the
symbols of acdk_core.
When you declare objects in executable, you don't need any export/import
macros:

class NewObjects : extends acdk::lang::Object=20

> This code can't be runned:
>      RStringBuffer sb1 =3D new StringBuffer("M");
>      RStringBuffer sb2 =3D sb1->clone();
This code should even not be compiled.
The clone() method returns a Robject and you should receive an error =
like
that:
 error C2440: 'initializing' : 'class RefHolder<class =
acdk::lang::Object>'
cannot be converted into 'class RefHolder<class =
acdk::lang::StringBuffer>'.

You have to cast the Robject result:
RStringBuffer sb2 =3D (RStringBuffer)sb1->clone();

See also:
http://acdk.sourceforge.net/acdk/docs/hb/lang/acdk_hb_lang_casting.html


> System::out->println(this->getClass()->getName());
> The result of this is "acdk::lang::Object".
ACDK uses metainfo / extented runtime type information generated by the
acdkmc compiler:

The first step is to modify the header:


ACDK_DECL_CLASS(NewObjects);

class NewObjects : extends acdk::lang::Object {
  ACDK_WITH_METAINFO(NewObjects) // THIS is for the metainfo
private:
	int myValue;
 =20
public:
	NewObjects(int intParam);
	virtual ~NewObjects();

	static int acdkmain(RStringArray args);

	void showValues();
};

acdkmc works for complete modules/directories. It also expects an header
file with the exact name of the directory. In this case acdktest1.h.

Then execute the metacompiler acdkmc:

C:\d\artefaktur\extern>ls
acdktest1  acdktest1.rar  acdkx_servlet

C:\d\artefaktur\extern>..\acdk\bin\acdkmc_d acdktest1
I: Analyse file: C:\d\artefaktur\extern\acdktest1\acdktest1.h
I: Analyse file: C:\d\artefaktur\extern\acdktest1\NewObjects.h

C:\d\artefaktur\extern>

This will generate 2 cpp files. Add the files to the project.
Then you will receive the results you expected.

1.
You have to enable RTTI in your compiler settings, otherwise nothing =
will
work - even if you eventually able to link the executable.
This aplies to all compiler on all platforms.

2.
On Windows you have to export classes/methods from you DLL you want to =
use
them outside the DLL.

Create a header in your library:

#ifndef mylib_Config_h
#define mylib_Config_h

#include <acdk.h>

#if defined(IN_MYLIB_LIB)
# define ACDK_MYLIB_PUBLIC ACDK_DLL_EXPORT
#else
# define ACDK_MYLIB_PUBLIC ACDK_DLL_IMPORT
#endif
#endif //mylib_Config_h

Now for the class inside your mylib:

class ACDK_MYLIB_PUBLIC MyClass
: extends acdk::lang::Object
{
  // ...
};

In the compiler settings for the mylib.dll project you have to define
IN_MYLIB_LIB.

In the compiler settings for the executable, which make use of =
mylib.dll,
you don't need to define this symbol.

Hope this helps,

Tja, so unterscheiden sich die Erfahrungen. >:->

Ich bin (nicht als Entwickler, sondern als "industrieller
Anwendungspartner") gerade im "Endstadium" (im doppelten Sinn) eines
gr=F6=DFeren Projekts, bei dem "nat=FCrlich" sch=F6n "trendkonform" alles in Java,
mit "Web Services" und HTML als Benutzeroberfl=E4che gemacht wurde -
Resultat: Denkbar ungeeignet, weil:

- viel zu lange Entwicklungszeit f=FCr die Prototypen dank Java im Vergleich
zu z.B. Python
- grotesker Aufwand und eher =E4rmliche Funktionalit=E4t f=FCr die
Implementierung der Oberfl=E4chen dank Struts/HTML gegen=FCber z.B. wxWidgets
- de facto keine M=F6glichkeit zur Anbindung von "loosely connected"
(meistens off-line) Clients, was in dem Anwendungsumfeld, um das es ging,
eigentlich essentiel gewesen w=E4re
- keine M=F6glichkeit zur Server->Client Benachrichtigung, also st=E4ndig
pollen (Software-Steinzeit)
- =DCbertragung nennenswerter Datenmengen (es ging z.B. um Echtzeit-Me=DFdaten
von Anlagen) verschlingt utopische Ressourcen
- und last not least: wirklich _=FCberall_ jede Menge Web-Server
installieren/konfigurieren/administrieren zu m=FCssen, nur um gew=F6hnliche
IPC/RPC zu machen ist alles andere als das, wovon der durchschnittliche
EDV-Administrator, der im realen Leben damit besch=E4ftigt ist, produktive
Anwendungen am Laufen zu halten, tr=E4umt.

Endergebnis: Alles f=FCr die M=FClltonne gearbeitet, nur weil sich die
"Szenekids" mal so richtig "austoben" wollten, anstatt sich an den
konkreten Anforderungen der Realit=E4t zu orientieren.

Nun habe ich mir im Laufe des Projekts ein Bischen was angelesen und
r=FCckblickend w=E4ren demzufolge z.B. Python (zumindest f=FCr den Prototypen und
um mehr ging es nicht), wxWidgets und Corba ideal gewesen.

Hi,

doch schon
so ziemlich alles haben, was man braucht...
<<
Es ist tatsaechlich ein Eigenbau.=20
Unter org::omg::* sind die offiziellen Interfaces definiert.
Der eigentliche ORB wurde unter acdkx::orb implementiert.

Es gab mehrere Gruende einen eigenen ORB zu bauen:
- Das offizielle IDL/C++ Mapping ist - um es vorsichtig auszudruecken -
verbesserungswuerdig.
  Das Mapping basiert in acdkx_orb auf die ACDK Standardtypen (wie z.b.
String, statt char*)

- IDL zu C++ ist nicht notwendig. Mit den von acdkmc generierten
Meta-Informationen hat man=20
  schon alle Informationen. Es gibt zwar fuer acdkmc auch ein
Attribut-Plugin =
(ACDK_CLASSATTRIBUTE(acdkx.orb.mc.OrbDispatchAttribute()))
  mit dem man statische Skeletons generieren kann (die dann in die
*metainf_ext.cpp geschrieben werden), aber das ist nicht umbedingt
  notwendig.
  Auf der anderen Seite gibt es ein Tool acdkorbidl um aus den bestehen =
ACDK
Klassen-Metainformationen IDL-Dateien zu generieren.
  Mit diesen kann man dann klassische C++- oder Java-Stubs fuer =
IDL-Kompiler
generieren.

- Einbettung in das DMI-Konzept. Die Klasse acdkx::orb::CorObject
implementiert einen generischen DMI Client, so dass man=20
  Objekte ueber CORBA/IIOP ansprechen kann, ohne dass man dies im
eigentlichen Code sieht.

- Erweiterung des CORBA/IIOP-Konzept. Das Protokoll ist auf der einen =
Seite
sehr komplex, auf der anderen Seite fehlen
  einige Dinge, wie polymorphe Funktionen. Hier wollte ich ueber IIOP =
auch
ein propriaeteres Protokoll realisieren, das
  remote-Aufrufe fuer alle ACDK-Klassen (und nicht nur Interfaces)
realisiert.

- Urspruenglich wurde acdkx_orb tatsaechlich als Bridge zwischen =
Java-ORBs,
C++-ORBs und ACDK entwickelt, das eigentliche
  IIOP-Prokoll sollte so einigermassen kompatibel sein.


Ich habe in den letzten Jahren das acdkx_orb-Paket nicht besonders
vorangetrieben (so ist DmiProxy-Konzept noch nicht vollstaendig
implementiert), da CORBA in meinem beruflichen Umfeld kaum/keine Rolle =
mehr
spielt.

Ich hatte sogar ueberlegt, ein eigenes - wesentlich schlankeres und auf =
das
DMI-Konzept von ACDK zugeschnittenes - Remoting-Protokoll zu schreiben, =
so
dass sowohl im Code des Clients wie des Servers es keinerlei =
Unterschiede
mehr macht, ob nun die Aufrufe remote oder lokal ausgefuehrt werden.

Da ich als kleiner Scripting-Dilettant Python ausgerechnet deshalb
verwende, weil es mir das "Herumw=FChlen" in solchen "Innereien" erspart,
kann ich dazu nix sagen. Mein Wissen endet damit, da=DF sich C(++)-Objekte,

Python-Objekte verhalten. D.h. man kann sie von Python aus auch zur

Genau darum geht es. Ich will kein C++ lernen oder gar benutzen m=FCssen, um

Hallo,

>> Wenn ich die Dokumentation richtig verstanden habe, erlaubt ACDK =
nicht,
serverseitige Anwendungen in Python zu implementieren?
Ich vermute die Dokumentation kommt aus dem Umfeld DMI-Server/Client. =
Das
hat nichts mit der klassischen Definition von serverseitige Anwendungen =
zu
tun.

Ein DMI-Client ist eine Sprachumgebung, die ACDK DMI-Server-Objekte
verwenden kann, als waeren sie (mehr oder minder) die eigenene Objecte.

Das Beispiel aus der Doku demonstriert dies:

=20
def foo(string1, string2):
  sb =3D acdk.Object("acdk/lang/StringBuffer", string1)
  sb.append(string2)
  return sb.toString()

acdk.peek_static("acdk/lang/System", "out").println(foo("Hello Python", =
"
from ACDK"))


Innerhalb von foo wird DMI-Server Object (in diesem Falle in ACDK C++
implementiert) und verwendet es, als waere es ein Python-Object.

Das "mehr oder minder" beschreibt den Grad der Integration. Der Aufruf =
von
nicht-statischen methoden geht sehr transparent, bei Zugriff z.B. auf
member-Variablen musste ich jedoch Hilfsmethoden, wie peek_static,
einf=FChren.

Aber nicht nur in C++ implementierten Objekte koennen innerhalb von =
Python
als DMI-Server verwendet werden, sondern auch COM-
(nur Windows), Java-, CORBA-, oder CfgScript-Objekte.

Hier ein snipped f=FCr ein COM-Objekt:

import acdk
classloader =3D acdk.Object("acdk/lang/ClassLoader")
classloader.findClass("acdkx/com/ComObject")   =20
word =3D acdk.invoke_static("acdkx/com/ComObject", "New", =
"Word.Application")
word.poke("Visible", 1)
doc =3D word.peek("Documents").Add()
sel =3D word.peek("ActiveWindow").peek("Selection")
sel.TypeText("This is ")
sel.peek("Font").poke("Bold", 1)
sel.TypeText("ACDK")
sel.peek("Font").poke("Bold", 0)
sel.TypeText(" instrumenting Word through acdk_python")
acdk.invoke_static("acdk/lang/Thread", "sleep", 3000)

Die beste Integration in ACDK hat zur Zeit CfgScript (ist im Modul =
acdk_core
enthalten). Innerhalb CfgScript lassen sich sogar=20
Innerhalb einer Scriptsprache C++ Klassen ableiten (inklusive =
=DCberschreiben
von virtuellen Methoden) und Interfaces implementieren, die innerhalb =
von
C++ (hier sozusagen der DMI-Client) verwendet werden k=F6nnen, als =
w=E4ren sie
native C++-Objekte.

Ich bin mir nicht sicher, ob es auch m=F6glich ist (bzw. wie schwierig =
das
ist), acdk_python so zu erweitern, dass Python-Objekte auch als =
DMI-Server
Objekte fungieren k=F6nnen. Wenn Python auf C-Ebene die M=F6glichkeit =
hat,
Typ-Informationen (inklusive Methodendefinitionen) abzufragen, sollte es
m=F6glich sein.

I've just find a bug in handling unicode character (like umlauts)

Have a look at the unit test for the java serialization: 
acdk_java/test/acdk/java/serialization/acdk_java_serialization_Basics_Te
st.cpp

If you want to serialize own classes from/to java, you have to create 
a corresponding ACDK class, derived from acdk::io::Serializable and 
with metainfo (the *_metainf_base.cpp and _metainf_ext.cpp). 
It is also important, that the member has the same declaration order 
and names as the Java class, otherwise a mapping has to be defined.

Please give me an example what does not working if you need further
help.

I'm currently playing around with acdk. 

I'm stuck at the serialization tests. Could you give me a simple example

I don't need to do an object mapping. I just have to be able to read the
