I am trying to get a simple example of the Diagram working in Silverlight. My problem is that I cannot seem to get the shapleListBox to display. Are there any examples I can download and use?

Here is the code I am using:

    <div style="border: 2px solid Green;">
       <ndiag:DiagramView ID="DiagramView1" runat="server" Behavior="DrawLinks"
           ClientSideMode="Silverlight" Height="256px"
           Width="256px">
       </ndiag:DiagramView>
    <br />
    </div>

   
    <div style="border: 2px solid Red;">
       <ndiag:ShapeListBox ID="ShapeListBox1" runat="server"
           style="background-color: white" ClientSideMode="Silverlight">
       </ndiag:ShapeListBox>
    <br />
    </div>

Actually, I was trying to get the Java version working but with no luck. I keep getting that 'magic value incompatible' error.

I was trying to sort that out when I found the error did not occur on the Silverlight version.

I think I will try the Java version again, and try to fix the problems with it. I have tried to extract the .jar in the directory, but still getting errors.

Yes, this usually happens because of Forms Authentication, but it could be caused by other problems as well. It seems that any HTTP reply that the Java plugin cannot recognize is handled as a binary stream from which the plugin tries to load the compiled Java classes. Then you get this message if there's no Java bytecode code in the stream but some unknown error response.

If you are using authentication, you can work around this by moving the applet to unprotected area of your site. If not, enable IIS logging and check what response is logged for the "GET JDiagram.jar" request.

If you have problems with shape libraries, make sure the file extension you are using is in the IIS Mime Types list. E.g. use "xml" extensions or add whatever extension you are using as text/xml type.

I don't know if we can host the file ourselves; we don't have any idea how many end-users our clients' applications will have in total and what kind of traffic that will generate

Hi Stoyo,

Does the jarLocation support full web addresses?

My company website is https://portal.aaa.com. But I am trying to host the JDiagram file at http://www.aaa.com/JDiagram

So I am using the asp:Diagram at https://portal.aaa.com/test.aspx, with the jarlocation set at http://www.aaa.com/JDiagram

Using fiddler, it looks like it is trying to get to https://portal.aaa.com/www.aaa.com/JDiagram !!

Hi Stoyo,

I have tried to access the JDiagram from my public site with no success. I have managed to get the Java console open, and I have pasted the results below. I have editted the location out, but I will sent the location to you via personnal message so that you can test it if you like.

The output below shows that java doesnt go to the public site to get the JDiagram file. (see the first http line)

Another issue I have found is that the aspx page that you put the control on must also be in a public folder. This is a little dangerous, but I can get around this.

Ah, of course you need the http:// part
