Hi Tobias,
That's indeed possible.
A singleton can be created by following these steps:
1. You first need to create an UNO interface for your extension (say
XConnectionManager)
2. The UNO singleton is then defined as follows:
published singleton theConnectionManager : XConnectionManager;
3. Implement the singleton by creating an implementation of the
XConnectionManager interface, say ConnectionManagerImpl.
4. Store the singleton by adding the following code to
__writeRegistryServiceInfo in you component registration class:
try {
XRegistryKey newKey =
xRegistryKey.createKey(ConnectionManagerImpl.class.getName() +
"/UNO/SINGLETONS/" + theConnectionManager.class.getName());
newKey.setStringValue("de.krais.tobias.sample.theConnectionManager");
} catch (InvalidRegistryException e) {
return false;
}
5. __getComponentFactory can be updated as you would do for an ordinary
service (no special handling for singletons required)
6. Now the singleton can be retrieved by calling
theConnectionManager.get(componentContext)
Hth,
Daan

I start OOo via API. Is it also possible to store the connection from
that code in a singelton and then use it later? In that case I won't
need a job.
Where can I find information about storing and reading a singleton?
