How does Web Start version of WIRED access data?
The web start version of WIRED can be started from the WIRED page on the data portal:
http://glast-ground.slac.stanford.edu/DataPortalWired/?tab=Wired
or from the "Browse Events with WIRED" link on some data catalog pages, e.g.:
http://glast-ground.slac.stanford.edu/DataCatalog/
In all cases a data catalog folder is passed to WIRED at start up, and this folder is subsequently used to search for run/events. The ability of a particular data catalog folder to be used as a source of events for WIRED is flagged by the existence of a eventComponents meta-data item on the folder. The value of this meta-data tells WIRED which groups hold the different event components, for example:
Name |
Value |
Type |
|---|---|---|
eventComponents |
digi=digi,reco=recon,mc=mc |
STRING |
When WIRED is started it is via a link of the form:
http://glast-ground.slac.stanford.edu/DataPortalWired/wired4.jnlp?folder=11628535
Node that the folder's primary key is explicitly passed as part of the URL. This URL is routed to the wired4.jsp file in the DataPortalWired web application, which dynamically creates the JNLP file to be used to start WIRED. For example the JNLP file created for the above link is:
<jnlp spec="1.0" codebase="http://glast-ground.slac.stanford.edu/DataPortalWired/" version="0.8.3.2">

Note in particular several properties are passed to WIRED:
Property |
Value |
Comment |
|---|---|---|
freehep.app.hep.wired.glast.gleam.defaultRunEventServer |
http://glast-ground.slac.stanford.edu/DataPortalWired//EventFinder |
Tells WIRED what web service to use to look for events |
freehep.app.hep.wired.glast.gleam.defaultDatasetFinderServer |
http://glast-ground.slac.stanford.edu/DataPortalWired//DatasetFinder |
Tells WIRED what web service to use to look for datasets |
freehep.app.hep.wired.glast.gleam.runEventServer.folder |
11628535 |
The primary key of the data catalog folder |
Web Services
DatasetFinderServlet
This servlet is used by WIRED to find which datasets to open. Given a folder it queries the eventComponents meta-data and returns the available event components. Example:
http://glast-ground.slac.stanford.edu/DataPortalWired//DatasetFinder+
returns a list of all folders which contain browseable events with 3 components per line:
- Folder primary key
- Folder path in data catalog
- Value of eventComponents meta-data
An example return line:
11655378 /MC-Tasks/ServiceChallenge/GRBgrid-GR-v13r9p20/runs digi=digi,reco=recon,mc=mc
