Create a Web Service Client using GSoap Toolkit over HP-UX Server

Introduction Sometimes, in our daily lives as developers, we have to integrate technology with different qualities. Sometimes, these products are expensive or some relative close to the business lines, for example, how to use an enterprise service overall the communication with legacy systems that is a tough question, so the first possibility to resolve this problem is using message queue or web service or any other component. There are many ways but the result should be measured and quantifiable for getting an approximation. Background I want to emphasize a scenario where you are using a HP-UX server you want to integrate with a web service, so typically, you have an interface that could be a WSDL, this legacy system can execute a library, by this way is a very fast solution but if you want to use XML on web service scenario to be communicated with a low-level system, you could use for instance a language like C (ANSI) or Python or cURL. If you have using web service client generator like axis2 or wsdl.exe, you should be familiarized with this toolkit called GSoap which is really fast and reliable in many aspects, if you search on the internet, you will get something like: "gSOAP is an open source C and C++ software development toolkit for SOAP/XML Web services and generic XML data bindings. ", Wikipedia The interesting part of the toolkit is that you will get C ANSI code generated on your stub, essentially all GCC compilers will translate his code. The interesting part of the toolkit is that you will get C ANSI code generated on your stub, essentially all gcc compilers will translate his code. Using the Code 1. Download GSOAP Toolkit The first step is download GSoap Toolkit from the following site: http://sourceforge.net/projects/gsoap2/files/ The second step should be to install GSoap Toolkit, unzip gsoap_2.7.15.tar in a root directory for execution. Example: C:/SOAP/ gsoap_2.7.15 There are two executable files that allow us to generate libraries for connecting to the Web Service: wsdl2h.exe soapcpp2.exe a.1 Run wsdl2h.exe: wsdl2h -c -o Archivo.h http://127.0.0.1:8088/WebService01/services/Enviar?wsdl -c Compilation in C -o Output File Reference Archivo.h Generation Archivo.h library interface http://127.0.0.1:8088/WebService01/services/Enviar?wsdl Web Service a.2 Run soapcpp2.exe: soapcpp2-c-C-L Archivo.h -c Compilation in C Customer-C Files -L Generation Archivo.h library interface 2. Get WSDL File from Web Service Endpoint GSoap can process the WSDL from the Web Service Endpoint only if the sitio does not have any kind of authetication that prevents direct access to web service. The most recommended option is directly get wsdl file from a web browser, taking care downloading the xsd files and change it form schemaLocation tag. 3. Generate Header File for the Stub Generate the Header File 'ClinicService.wsdl' that has the necessary structures and procedures to generate the stub, it is important to note that the file will guide us to implement a web service client. Example: C:\SOAP\gsoap_2.7.15\gsoap\bin\win32>wsdl2h -c -o ClinicService.h D:\CODE\wsdl\clinic\ClinicService.wsdl ** The gSOAP WSDL/Schema processor for C and C++, wsdl2h release 1.2.15 ** Copyright (C) 2000-2009 Robert van Engelen, Genivia Inc. ** All Rights Reserved. This product is provided "as is", without any warranty. ** The wsdl2h tool is released under one of the following two licenses: ** GPL or the commercial license by Genivia Inc. Use option -l for more info. Saving ClinicService.h Cannot open file 'typemap.dat' Problem reading type map file 'typemap.dat'. Using internal type definitions for C instead. Reading file 'D:\CODE\wsdl\clinic\ClinicService.wsdl'... done reading 'D:\CODE\wsdl\clinic\ClinicService.wsdl' To complete the process, compile with: soapcpp2 ClinicService.h If we open the file containing struct ClinicService.h, notice that they are related to the input parameters and return variables. Example: C++ struct _ns1__ejecutarServicio { char* tipoServicio 0; char* parametro 0; }; Another important point is that we handle struct for C (ANSI), if we had used the-c parameter in wsdlh.exe, would have generated code in C + +, and this does not benefit us in the HP-UX terminals. 4. Generate the Stub With ClinicService.h header file, we can use the following executable: C:\SOAP\gsoap_2.7.15\gsoap\bin\win32>soapcpp2 -c -C -L ClinicService.h ** The gSOAP code generator for C and C++, soapcpp2 release 2.7.15 ** Copyright (C) 2000-2009, Robert van Engelen, Genivia Inc. ** All Rights Reserved. This product is provided "as is", without any warranty. ** The soapcpp2 tool is released under one of the following three licenses: ** GPL, the gSOAP public license, or the commercial license by Genivia Inc. Saving soapStub.h annotated copy of the input definitions Saving soapH.h serializers Saving soapC.c serializers Saving soapClient.c client calling stubs Using ns3 service name: ClinicServiceSoap11Binding Using ns3 service style: document Using ns3 service encoding: literal Using ns3 service location: http://127.0.0.1:80/ClinicService/services/ClinicServiceHttpSoap11Endpoint/ Using ns3 schema namespace: http://clinic.com/ClinicServiceSoap11Binding .... Compilation successful If we observe the command line, are generated 4 files extension *.c Files generated need the following: Archivo Definición 1. soapH.h Main Header File 2. soapC.c File with Data Structures 3. soapClient.c File with the implementation of the methods in C Web Service 4. ClinicService Soap12Binding.nsmap ClinicServiceSoap11Binding.nsmap Struct with corresponding namespaces Soap versions 1.1 and 1.2, this according to the version you wish to use. 5. Header File for the Library We continue to write the library in first generating Header File (ClinicServiceWS.h). C++ #if defined(__cplusplus) extern "C" { #endif #ifdef WIN32 __declspec( dllexport ) #endif void ejecutarServicio(char *endpoint, char *usuario, char *contrasenya, char *tipoServicio, char *parametro, char *respuesta, char *error, char *llave); #if defined(__cplusplus) #endif This file contains the public firm library SL / DLL. 6.

Compilation Shell The next thing is to compile the component on a HP-UX Terminal, so we need to ask the following fact: When HP-UX compile, our programs must be generated in 64bit for other programs running on the server can open the library and their corresponding links, the common misconception regarding compilation this program is on the library dld.sl. Finally, this is shell you could run on HP-UX Terminal, the reason is to compile all your source and get a library with *.sl extension.

Points of Interest We can create web service clients running as a C++ library for a system that works under low-level, we essentially create a stub of web service interface to communicate under TCP with web service deployed in any technology.

How to install ssh terminal on your own network? (Part 01)

Introduction 

In terms of having a well redundant network for develoment in my personal opinion you must have a common protocol to comunicate between servers, as my regarding supposition the correct and common protocol is ssh, this article provide several steps to join and conclude a quick reference for the installation.

Development

Case: Installation of WSL/Ubuntu/Windows upper 10+

sudo apt install openssh-server

sudo nano /etc/ssh/sshd_config

Modify next lines:

/etc/ssh/sshd_config

...STUFF ABOVE THIS...

Port 2222

#AddressFamily any

ListenAddress 0.0.0.0

#ListenAddress ::

...STUFF BELOW  THIS..

service ssh start

netsh interface portproxy add v4tov4 listenaddress=0.0.0.0 listenport=2222 connectaddress=172.23.129.80 connectport=2222

netsh advfirewall firewall add rule name=”Open Port 2222 for WSL2” dir=in action=allow protocol=TCP localport=2222

netsh interface portproxy show v4tov4

#erase everything

netsh int portproxy reset all

Case: Installation between networks

1. Check fqdn in proper file of windows operating system:

Check this file as Administrator user:

c:\Windows\System32\Drivers\etc\hosts

Add the following line described below:

172.177.126.3 localhost machine-name

2. Configuration of firewall in Linux Machine

• sudo ufw status verbose
• sudo ufw allow 22/tcp
• sudo ufw status verbose
• sudo ufw allow http
• sudo ufw allow https
• sudo ufw allow 80/tcp
• sudo ufw allow 443/tcp
• sudo ufw allow 53
• sudo ufw status verbose
• sudo ufw allow from 192.168.1.10 to any port 22
• ufw allow from 192.168.1.0/24 to any app Samba
• sudo ufw app list
• sudo ufw status numbered
• sudo ufw delete {num}
• sudo ufw delete 5
