Common Issue with Certificates created on Windows

One of the common issues faced when dealing with certificates for doing SSL communication or WS-Security is that the certificates created on windows does not work on Linux. This is due to the addition of Windows Specific characters to the certificate. I have seen so many users struggle to get SSL/HTTPS working due to this problem.

So easiest thing to do, if you want to run a client with HTTPS on Linux with a certificate created on windows, just do a dos2unix on the certificate.  :)

This should help you save a lot of time.

Building WSF/PHP with PHP 5.3.0

Since the release of PHP5.3.0 number of requests were there inquiring the compatibility of WSF/PHP with PHP 5.3.0.  I tried it out on windows and I only encountered minor issues. These issues are now fixed on the svn trunk. Here is how you can build WSF/PHP from the svn source to use with PHP 5.3.0.

First download both PHP 5.3.0 source and binary distributions from php.net. You will also need to download the binary tools such as bison.exe which are required to build the PHP source.

Next you need to run the buildconf.bat contained with the php source in order to build the windows specific headers.

Now you are ready to build wsf/php for php 5.3.0.

Get the svn source of wsf/php from  https://wso2.org/repos/wso2/trunk/wsf/php.

svn co http://wso2.org/repos/wso2/trunk/wsf/php wsfphp

Now cd to wsfphp directory and open the configure.in file and set php configurations as follows.

PHP_SRC_DIR = E:\php\php-5.3.0
PHP_BIN_DIR = E:\php\php-5.3.0-Win32
BINDLIB_DIR = E:\php\bindlib-cvs-vc8

Of course you need to set the other dependencies according to your machine configurations.

Now run the build.bat file. This will build wsf/php binary for php 5.3.0

Servey: Tools for PHP Web Services?

This is a servery to find out, what PHP progremmers need the most when it comes to dealing with Web services.

Please feel free to comment on this blog post.

What is your wishlist when it comes to PHP Web servies? What tools are you looking for?

How about something similar to PHP MyAdmin for PHP Web services? Point to the service, and just use it?

What about hosting? Do you have trhoube consuming services from hosted PHP instances?

What about IDE integration? Would you like it to be intergated with, say, Eclipse?

Feel free to let us know.

WSO2 WSF/CPP 2.0.0 Released

WSO2 WSF/CPP 1.0.0 was released sometime back with the intention of providing a C++ API for C++ developers while leveraging the capabilities of WSF/C Web Services Stack. It only had the Client API. With this new release,the product has been significantly enhanced with the addition of a Service API, Code Generation support for C++, and Many WS-Security features. WSF/C++ can be deployed on both Apache2, and IIS. Also it has the stand alone http server as well. You can download WSF/C++ from http://wso2.org/downloads/wsf/cpp.

Here is the complete release note.

Dealing with Log files

WSF/PHP uses two log files to log down certain messages useful for tracing and debugging incase of an error. These logs are handled by the underlying WSF/C Framework. It supports a log rotation as well.

Following are the log level supported by WSF/PHP.

Log values are set to the wsf.log_level php.ini entry.

0 -> CRITICAL  ( Only critical errors will be logged )
1 -> ERROR      ( Errors will be logged)
2 -> WARNING  ( Errors and Warnings will be logged)
3 -> INFO       ( Errors , Warnings and Information will be logged)
4 -> DEBUG   ( All log messages including debug messages will be logged)

When you have enabled log higher log levels, a large number of log messages are done to the log file which result in the log file growing rapidly with the number of messages processed. This would not be a problem if you are running your system for testing. But if you are running it on production this could cause some problems, because we noticed that these is a issue in the log rotation scheme for WSF/PHP 2.0.0. Due to this issue, a number of users have complained that apache stopped working as well. Therefore it is recommenced that you used the log level 0 on production systems.

Case Study - PHP Data Services To Extract Content from Drupal Database

In this case study " PHP Data Services Extract Content from Drupal Database", I intended to present how Data Service concepts can be applied to extract data with marketing value from a CMS database and publish it as web services. I used the drupal instance deployed at http://wso2.org as the CMS for the use case. And as the data service framework, I used WSF/PHP data services library, as it requires minimum changes to the existing infrastructure (the LAMP stack).

Article Introducing PHP Data Services

Now you can view the article "Introduction to PHP Data Services" from Oxygen Tank library.

If you are thinking of adapting SOA in to your database backed PHP applications, this article will be a good starting point.
