Querying multiple/all layers in multiple in multiple mapservers?

[psingh]

Hi,

Is it possible to query multiple layers in multiple mapservers?

If someone can help or guide me towards a way to achieve this, I'll greatly appreciate it.

Thanks

Not in one call.  You can only query against one layer at a time, but you could send multiple requests to achieve your multiple layer query functionality.

You might also want to look at FindTask and IdentifyTask.  They both work with a mapservice (as opposed to a layer within a mapservice like Query).  Depending on what/how you want to query, they might be helpful.

Hi,

Thanks a lot for response.  FindTasks does exactly what I was looking for.

I have one issue though - I have multiple findtasks define in the application and the second one doesn't run at all.  The executeComplete method is not returning anything.

If someone can help, I'll greatly appreciate that.

I just added a "fault" statement in the call and it is indeed failing.

This is the error:


TypeError: Error #1010: A term is undefined and has no properties.
