Thank you for your help!
I'm seeing that the code you posted is very similar to the buffer code,
however I'm really new to MapGuide, so I hope you can help me understanding
how to make it work.
I created a Layout, using MapGuide Studio, on which I added a new custom
command for the Task panel, named "Route tracing". Therefore I created the
route_tracing.jsp file, on which I'm trying to use your code (translating it
from PHP to JSP) or the buffer.jsp code (which is already in JSP).
On both your code and buffer.jsp there is this code:
mapName = GetParameter(request, "MAPNAME");
sessionId = GetParameter(request, "SESSION");
- The question is: how can I pass the MAPNAME and SESSION values to the web
page?
The final result should be a web page, which opens when its Action Task item
is clicked, on which I can select and digit some options. After clicking a
button the page should get these values, and display the map with the
calculated additional layer on it.
I hope you can help me about that
Cheers
Carmelo
