| The WPS is based on SOM the [http://en.wikipedia.org/wiki/System_Object_Model System Object Model], an implementation of an ORB compatible with an older (version 1.1) CORBA specification (remember SOM wasn't updated for quite a while. At hobbes exists newer SOM implementation, but some ppl reports problems with it).

| There's a lot of fuzz about how advanced the WPS is because it uses CORBA etc. bla bla. In fact most of the features of the WPS don't need a fully CORBA compliant ORB and more important don't use it. While Distributed SOM (DSOM) is coming with OS/2 the WPS seem to use only local SOM.

|
| Note: It is possible to use DSOM for WPS objects access. You need to start WPS DSOM server first.

| While it's possible to query, load, unload and replace SOM classes on demand during program execution the WPS usually builds its class tree during initialization. Thus class replacement requires a WPS restart. Note that adding of classes can still be done without a restart.
| |
| Saying this that doesn't mean you never can replace a class during runtime. It's always possible to bend the borders with some serious hacking but there's no general API for that.

| ===Prerequisites===
| |
| | |
| * SOM compiler - Contained in the OS/2 toolkit which comes with your commercial compiler or eCS.
| |
| Or at http://hobbes.nmsu.edu/pub/os2/dev/wps/somobjtk.zip
| |
| or at http://hobbes.nmsu.edu/pub/os2/dev/wps/opendc12.zip
| |
| * C compiler - Visual Age 3.08
| |
| Or any C/C++ compiler. Open Watcom was tested for easy tasks and all works fine
| |
| For other languages you need to write emitter
| |
| | |
| ===Programming===
| |
| | |
| * [[Short overview]] how WPS programming works in general.
| |
| * [[Tutorial]] for a simple WPS class.
