Yap, that's it. I was thinking of storing my binaries directly on MG server - as in WebServerExtensions, just without that Web part :-) That would speed the thing up as much as possible, getting to the repository as close as it gets. Linking to (copied) MG binaries is not a problem, did it before. Then I should go atfer some Silverlight-enabled visualizations of underlying vector data. We'll see what comes out... :-) Regards, Maksim Sestic

But it does require the "serverconfig.ini" file, and the correct version of the MgApi binaries. You can use the IServerConnection interface, and then change the connection depending on your access needs: ServerConnectionI con; if (servername == "localhost") //Perhaps check for LAN? con = new LocalNativeConnection(...); else con = new HttpServerConnection(...); LayerDefinition layer = con.GetLayerDefinition(...); Regards, Kenneth Skovhede, GEOGRAF A/S Maksim Sestic skrev: Hi Kenneth, Thanks for the clarification, I didn't get the concept of Maesto API LocalNativeConnection in first place. The assumption is - if I develop a managed server-side component relying on Meastro API LocalNativeConnection, then it would use the headerless loopback connection to MG repository (aside from managed object (de)serialization)?

If you create a MgResourceService object, you are talking to the repository. And MaestroAPI uses this (with a LocalNativeConnection) to talk to the MapGuide server. I have not followed it all the way, but I think that the MgResourceService is about as close as it gets, to the repository content. Alternatively, you can use DBXml and read the database directly, but that is a recipie for trouble. Regards, Kenneth Skovhede, GEOGRAF A/S Maksim Sestic skrev: I agree, the thing is that there's no MG managed wrappers we can leverage to talk to the repository manager directly. If we had one, we could start from that point on. Could we use Meastro API for repository objects serialization/deserialization in managed fashion then?

I think the server is (partly) divided, with one part being a repository manager. You can already retrieve resources with calls, and coordinate data with another. The MgApi interacts directly with the server, it is still serialized, but binary. The MgApi uses the loopback connection, but does not use a webserver, and has no http headers. So you can still do it, but I agree that it would make sense to divide the different parts more rigidly. Regards, Kenneth Skovhede, GEOGRAF A/S Maksim Sestic skrev: Hi Kenneth, I guess that someone :-) needs to build a tier-neutral repository viewer first, then leverage it's API via Silverlight/Moonlight. Presumably using .NET. Currently, the engine is called MapGuide Server :-) but it's kernel is server-tier oriented and any external communication with it goes via Http on mandatory base. It would be perfect if we had respository manager as a separate API - representing the actual core. Then, a web-tier API (another component) leverages repository API to talk over Http with thin clients. So developers might pick if they want to use either web-tier approach (i.e. JavaScript) or want to talk via SOAP/linking to the repository manager directly. Don't know actually... just a couple of thoughts from my side.

I would prefer Silverlight over Java because it intergrates better with the html DOM (IMO). As for codebase, the current viewers are based on Javascript, and they are limited to manipulating pre-rendered images. The DWF viewer is some of it, but it is still ActiveX based. I suppose one could make plugins for all browsers, but it still difficult to persuade regular web users to install it. Since Silverlight/Moonlight is more likely to be installed already, and backed by Microsoft, it will probably be easier. Flash is another option, but it is terribly hard to work with (IMO). Regards, Kenneth Skovhede, GEOGRAF A/S Carl Jokl skrev: I think that there could potentially be a number of alternatives to using an Active X based viewer. I could see potential also for both Flash or Java to create a viewer too. One problem with the Active X viewer in relation to the clients of the company I work for is the security / administrative problem for our clients. Organisations internet security policies could interfere with deployment of an Active X control. I would think though that the same issue would apply to a Java based viewer too. Silverlight might work better in this regard. One of the reasons I find the Java option interesting is the availability of JOGL essentially allowing a Applet or Web Start application to be able to take advantage of Hardware accelerated graphics. I don't know if any alternative viewers have been worked on. If much of MapGuide is open source would that include the viewer? If so it might be possible to start from the existing viewer source code and port it to another platform.

Such a viewer should be able to achieve performance that is comparable to the MapGuide 6.5 viewer, without the need for an ActiveX plugin. -- Regards, Kenneth Skovhede, GEOGRAF A/S _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users __________ NOD32 3219 (20080625) Information __________ This message was checked by NOD32 antivirus system. http://www.eset.com _____ _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users __________ NOD32 3219 (20080625) Information __________ This message was checked by NOD32 antivirus system. http://www.eset.com _____ _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users __________ NOD32 3219 (20080625) Information __________ This message was checked by NOD32 antivirus system. http://www.eset.com _____ _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users __________ NOD32 3219 (20080625) Information __________ This message was checked by NOD32 antivirus system. http://www.eset.com
