Can C/C++ ''do'' Web services?
- By John K. Waters
Developers working with J2EE and .NET technologies are swimming in a
veritable flood of tools for creating Web services. Yet the majority of core
enterprise applications are written in C, C++ or COBOL. Many of the world's
critical performance-oriented apps are written in C++, but for developers called
upon to expose the functionality of those applications as Web services, the
tools gush has been more of a trickle.
Component specialist Rogue Wave Software added to the flow last week with
Version 1.2 of its Lightweight Enterprise Integration Framework (LEIF). First
announced in February, LEIF is designed to allow developers to integrate
existing or new C++ client and server applications with .NET and J2EE
applications and Web services.
''This new release should facilitate the adoption of Web services and XML by
companies with large investments in C/C++,'' said Rogue Wave Senior Product
Manager Tim Triemstra in a statement. ''Many companies that fit this profile
understand the promise of Web services, but have delayed adoption of this
technology because of the perceived difficulty of working with Web services in
Although it is a high-performance language, C++ is a ''compile time'' language,
which makes it difficult to map C++ with dynamic systems like Web services. LEIF
1.2 is a framework and set of wizards designed to enable C++ interaction with
J2EE and .NET within the enterprise, as well as to customers or partners. LEIF
provides solutions based on standards such as HTTP (client and server), SOAP,
WSDL and XML. And it is designed to provide support for a broad range of
operating systems and C++ compilers from vendors such as Microsoft, Red Hat,
SuSE, Intel, Sun Microsystems, IBM and Hewlett-Packard, Triemstra said.
Key enhancements in LEIF 1.2 include a GUI Project Wizard, so-called
Pluggable Protocols that allow developers to write and use transports other than
the default HTTP, and XML document validation. Also on tap: improved fault
support for better error handling and support for SOAP faults.
