[Paraview] 回复： 回复： Open remote file Error via Paraviewweb (Paraview3.98.0)

[Ewin]

Thank you very much, Seb.
Following your instructions, I resolved it!






------------------



You can not do anything before connecting.As when you connect, the created proxy will be deleted.
The creating of the view need to happen after your Connect() call.

 Hi Seb,
    I found the point which cause the "OpenDataFile" error: when I executed < paraview.Connect("172.168.0.47", 11111); >, the view died. 
 But I still don't know How to fix it.


    Here is all my code:
----------------------------------------------------
 <script type="text/javascript" language="javascript" src="/PWService/js/ParaViewWeb.js"></script>
<div id='container_id'></div>
<script>
 	serverUrl = "<%=request.getScheme()%>://<%=request.getServerName()%>:<%=request.getServerPort()%>/PWService"; 
	paraview = new Paraview(serverUrl);
 	paraview.createSession("Session", "vispurpose", "default");
	myview = paraview.CreateIfNeededRenderView();
 	var reader;


 	paraview.Connect("172.168.0.47‍", 11111); // !!! delete this line, the code will be work!
 	
	val ="/home/tiandong/bluntfin.vts";
	reader = paraview.OpenDataFile(val);
 			
	dp = paraview.Show();
        paraview.Render();
 

	renderers_java = new HttpAppletRenderer("javaRenderer", serverUrl);
	renderers_java.init(paraview.sessionId, myview.__selfid__);
 	renderers_java.setSize(600 , 600);
  	renderers_java.bindToElementId('container_id');
	renderers_java.start();
 </script> ‍

----------------------------------------------------‍


   the pvserver is connected, server shows:
 ----------------------------------------------------
$ ./pvserver 
Waiting for client...

 Re: [Paraview] Open remote file Error via Paraviewweb (Paraview3.98.0)


 




Hi Ewin,

this version of ParaViewWeb is so old, that I don't remember it on top of my head.


I will guess that the view was not properly created. (myview) hence the NoneType.
 Moreover, you will have an issue with "wirefire" which should be "Wireframe" I believe.

 Hi all,
     I want to show paraview result on webpage,  and I setup the paraviewweb envi (version 3.98.0). 
      Method "paraview.loadData" can get a normal source object and show well, but it can only open native file. So, I use "paraview.OpenDataFile" to read the remote file, but I got an Error:
  
      'NoneType' object has no attribute 'Representations'‍
     
     My Code:
             paraview = new Paraview(serverUrl);‍
            ......
           var reader = paraview.OpenDataFile(val);‍
            paraview.SetDisplayProperties( {
		'proxy' : reader ‍,
 		 'view'  : myview,
		Representation : 'wirefire‍'
 	    } );‍


Any help will be appreciated！
Thanks all！
