Error executing print task

philippschnetzer — Wed, 15 Aug 2012 10:57:32 GMT

Using the server 10.1 and flexviewer 3.0

I am getting the following error after creating my own printing service (so that I can create custom layouts):

Error executing print task: [RPC Fault faultString="Unexpected < encountered at location 5" faultCode="null" faultDetail="null"]

I followed the instructions here: http://resources.arcgis.com/en/help/main/10.1/index.html#/Publishing_additional_services_for_printing/00570000009s000000/

I registered my folder containing the mxds with the server manager and when i load my web app i can see all of my mxds available as options in the "Layout templates" dropdown box using the out-of-the-box print widget.

As soon as I switch the <taskurl> in the printwidget.xml to use esri's service my print widget works fine...

Any thoughts?

Can you see what the response from the server is using a tool like HttpFox?

I installed httpfox...not exaclty sure what I am looking for..but, under POST Data it says "(This request contained no POST data)".

Here's the line that appeared when the error appeared:

Time 100.346 Sent 2167 Received 974 GET Result 200 Type text/html

Also, here is what was under Query String:

Web_Map_as_JSON {"layoutOptions":{"authorText":"dfgsdfg","titleText":"sdfgsdfg","copyrightText":"sdfgsdfg","legendOptions":{"operationalLayers":[{"id":"LAYERS"},{"id":"ACTIVE MUN.

The response should be shown in the Content tab.

Here's what was in the Content tab:

Doesn't look like this is of any help...but like I said before I'm not sure what I'm looking for...

Thanks again!

The fault "Unexpected < encountered at location 5" is because this is HTML coming back from the server instead of JSON so the JSON parser fails.

The HTML seems to be coming from the ArcGIS Web Adaptor saying "The operation has timed out".

I'd suggest contacting Esri Tech Support at http://support.esri.com/

I got it working, after I enabled the JSON mime type on the server (Windows Server 2008R2, IIS 7) it works fine. Here were my steps:

Open IIS Manager

Display properties for the IIS Server

Click MIME Types and then add the JSON extension:

File name extension: .json

MIME type: application/x-javascript

Go back to the properties for IIS Server

Click on Handler Mappings

Add a script map

Request path: *.json

Executable: C:\WINDOWS\system32\inetsrv\asp.dll

Name: JSON

By the way, being able to send a map to our own layouts is pretty great...kudos

im gonna post here again in case someone else needs to know...

turns out I was only temporarily right, adding the json mime type worked for about 5 or 6 exports and then the same error (as above) returned...

back to the drawing board...
