Hi Richard,
Thanks to you and Holger for your assistance. This has been a strange
one.
Per Holger's suggestion, I checked for my service using the "Available
Web Services" page. My service was in the list and displaying
properly, including the prefix. There were no base URI issues either.
The SWP is a direct subclass of ui:Service and is declared in the
.ui.ttlx file, so no issues there.
Next, I checked the prefixes. First, I attempted to run the SWP using
the fully qualified URL. It worked! Thus a prefix must be the
problem. Using this query, I listed all the imports into my SWP
graph. Nothing jumped out as a problem.
SELECT *
WHERE {
?s owl:imports ?o .
}
To find where my prefix might have been used, I switched perspectives
and ran a full text search of the entire workspace. I found that the
same prefix (l5x) was defined in an example file that I had prepared.
This file is /not imported/ by anything in the workspace, including my
SWP. I was able to change the prefix in that file, refresh system
registries and now the prefixed SWP call works properly.
And the file also did not end with .ui.ttlx by any chance? All those ui.
files are merged together into a large union graph, and the services
will respond using that graph. If it is indeed not referenced and has no
.ui.* ending then I have no idea why it would use that conflicting prefix.

Obviously using the same prefix for different graphs is not a
good practice. This instance resulted from me copying my SWP file to
the example file and stripping it down to create a unit test for
another problem I'm having. Thus, this was an oversight. I can see
where using the same prefix for two different graphs would be a
problem if they were imported into the same import closure (not the
case here). Should it have been a problem since the two graphs never
connected other than being in the same workspace? If using the same
prefix is an issue and TBC is scanning the files to harvest prefixes,
is it possible to generate a warning when duplicate prefixes are found?
Thanks again for your assistance. Off to the next problem :)

The org.eclipse.jface message and stack trace is probably
unrelated and harmless.
The message “Not a registered SWP service class” indicates that
the class passed as _viewClass is not of type ui:NodeClass, taking
subclass inference into account. The type statement must be in the
UI graph, that is, in a graph whose graph URI ends in .ui, or in
the owl:import closure of such a graph.
This can be verified by asking this SPARQL query (written here
from memory):
ASK { GRAPH ui:graph { ?viewClass rdf:type/rdfs:subClassOf*
ui:NodeClass } }
Where ?viewClass needs to be replaced with the value passed as
_viewClass.
If _viewClass is a prefixed name, then a missing prefix
declaration, or clashing declarations in different graphs included
into the UI graph, could also cause this problem. This possibility
can be excluded by using the full URI as the value of _viewClass
(%-encoded if it contains # or &).

Hi,
I've been running (and working on) the same set of SWPs for weeks
now and this evening I'm getting the "Not a registered SWP..."
error message.
It's the same file, (*.ui.ttlx), same class, etc... I've had the
error before, usually when there is some sort of import problem
but no errors about that now. Typically refreshing the system
entries does the trick. No luck this time.
I restarted TBC into a new workspace and imported everything from
the previous one. The SWP is still unregistered. I did receive
a few instances of this error during the import:
*Problems occurred when invoking code from plug-in:
"org.eclipse.jface".*
The stack trace is below and seems to indicate something related
to TBCFileRegistry. Is there a way to see what SWPs are
registered? Can I trace this error further somehow?
Thanks,
Tim
