| The WPS is based on SOM the System Object Model, an implementation of an ORB compatible with an older CORBA specification (remember SOM wasn't updated for quite a while).

| 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. And limitation is only Workstation DSOM can be used (distribution across local processes)

| | |
| 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.
