Hi Cameron,
i see you understand the problematic of my issue. I have an existing
Java/JSP application and want mapbuilder to collaborate with my app.
Maybe i have to expand the scope a bit:
Mapbuilder works very fine as a simple mapviewer. You have an OGC
WMC-document as model which contains all of the information a map
needs to rendered - that's really good! But after all that's a static
approach. For my problem i need more dynamic one: I want to add the
WMS-Layers of a CS-W catalogue-search to the Map. therefore i need to
1. Bridge Metadata and Geodata
2. construct session-dependent WMC-Files for each user
3. reconfigure the WMC on the file system
For these heavy duties i need a more mighty tool than JS.
But you're right there are problems in bridging data between
client-side scripting and server-side scripting. O.K. there are
interfaces like rhino from mozilla, but they are very
platform-dependent.
Like i use mapbulder (as a visualization backend) i never had to
exchange data until now, because the only "interface" was the WMC
'til now. But for a trimming-functionality of the WMC-layers i had to
gather information of the checked layers from the legend widget. I
tried to reach it with a JS-function, but got the problems like told
above. Now i got a hint from Darren Graham how to get the
attribute-information of the Layer-checkboxes. I think i can use them
with JSP now too.
Best regards
Albrecht
