Web services provide an excellent means for users to take advantage of algorithms and computing time on machines that are physically displaced from their location. We can construct tools that are essentially platform and language independent by using XML, specifically SOAP, as the communication language between client and server. This allows for a large set of utilities to be built for use by the entire astronomical community via simple client programs.
We present a case study in which we have deployed the popular source extraction code ``SExtractor" in a web service. ``SExtractor" takes an input FITS image and output a catalog of sources with associated parameters. Our web service provides the additional option of cross matching the resultant catalog with other previously published data sets (i.e. SDSS, 2MASS, FIRST, HDF, etc.) through the SkyPortal web service provided by OpenSkyQuery. This is an important step in the development of web services as we begin to use pre-existing web services to build increasing utility into the set of tools available.
