Edit Widget & Attachments

BarrettStanke — Fri, 15 Oct 2010 19:32:19 GMT

When I edit locations within viewer 2.1, all my edits save properly but clicking the link to the attachment opens another window but the file doesn't open and I get a dreaded HTTP 500 Internal Server Error. How do I go about correcting this?

Also, is there a limit to the size of file you can attach? Having trouble with anything over 5 MB.

When I edit locations within viewer 2.1, all my edits save properly but clicking the link to the attachment opens another window but the file doesn't open and I get a dreaded HTTP 500 Internal Server Error. How do I go about correcting this?

What is the URL that it is trying to open? It should probably be similar to something like:
http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/SanFrancisco/311Incidents/FeatureServer/0/1658885/attachments/30882 ...

Also, is there a limit to the size of file you can attach? Having trouble with anything over 5 MB.

Yes, both the web server and ArcGIS Services can limit the file size. Both are configurable.

.NET
The max allowed upload size is the smallest value defined by:
a. <MaxUploadSize>20480</MaxUploadSize> as defined in rest.config.
or
b. ASP .NET Max Request length as defined in web.config
<httpRuntime maxRequestLength=10240" />.
See http://support.esri.com/index.cfm?fa=knowledgebase.techarticles.articleShow&d=35971 for more info.

Java
The default max allowed upload size is 20 MB. This can be modified by setting "config.max-upload-size" property in rest-config.properties.

The URL seems to be correct:

http://emrgisviewer.emr-inc.com/ArcGIS/rest/services/CPR/CPR_Data/FeatureServer/2/818/attachments/801

The linked docs are in a sub folder of the wwwroot\cprr directory where the config.xml and widget files are. Do I need to move them or should they be somewhere else?

Got this part to work. Thanks.

There seem to be some authentication issue going on with your web server.

If I navigate to it via the REST Service Directory, I can see that it has one PDF attachment:
http://emrgisviewer.emr-inc.com/ArcGIS/rest/services/CPR/CPR_Data/FeatureServer/2/818/attachments

but when I click the PDF link:
http://emrgisviewer.emr-inc.com/ArcGIS/rest/services/CPR/CPR_Data/FeatureServer/2/818/attachments/801

I get an "Unauthorized" error:
Server Error - The remote server returned an error: (401) Unauthorized.
Code: 500

I just started working with attachments on our internal sites and i get the same issue of unauthorized when i attach a file. What base permissions are required to be able to access the attached files?

Thanks..

Did finally get this to work properly.

For future reference, part 1 of the problem was the virtual output directory was pointing to the wrong folder. Within our GIS server -> server properties -> all virtual directories were pointed to the improper viewer name. First stopping all map services prior, had to put in the proper viewer name for all 5 directories (Cache, Index, Input, Jobs, and Output). Then restarting the map services.

Part 2 of the problem was insufficient permissions to the arcgisserver folder for the internet guest account. Fixed by adding this user account (IUSR_) to the list of permissible user names under the folder properties -> security tab.

I am having essentially the same problem, however, mine is not an authorization issue. I get an error telling me that there is an Internal Server Error (500). I can go to the url for the attachments and see that they do exist for the feature service, but when I try to access them through a Flex project, I get the Internal Server Error message rather than getting the option to download or view the file. I cannot seem to figure out what I am missing that is causing this problem.....any suggestions?

I'm having a similar issue getting to the attachments from the Edit widget. I'm getting the error:

500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

The directory it is pointing to is:
http://www.fishcda.com/ArcGIS/rest/services/SampleEdit/FeatureServer/3/411/attachments/2

I can see the attachment being created in my arcgisoutput folder when I click to view the attachment, it is named some crazy long name, but when I open it up on the server is is the image I requested that was an attachment.

I have added the IIS_IUSRS account to have read access the arcgisoutput directory, and the som and soc already have permission.

Any Ideas?

I have created an editable layer and enabled attachement for the feature class in the SDE GDB.

Adding and editing features with the Edit widget works perfect, but no attachment button is displayed in the attribute dialog window. Will I have to enable attachment in the widget config file or something like that?

You first may want to check at the rest end point for the feature service and make sure that you see "Has Attachments: True" (this is found about 11 topics-bold text down on the rest end point).

You then should make sure the you can see popUps for the feature layer. You will need to configure a PopUp.xml file for it. This way you can make sure you can get to the attachments. Make sure you set <showattachments>true</showattachments> in your PopUp.xml.

If you get the above working then the edit attachments may have a higher chance of working. Feel free to chime back in if this has already been done and works.

Thanks for your response Frank,

I suppose I have misunderstood the function of attachments. I thought it would be possible for users to upload attachments to the features in the editable layer from the edit widget, which would be very useful for our users.

FrankRoberts — Fri, 05 Aug 2011 13:28:32 GMT

Ivan, you are correct that you can upload attachments via the editable layer using the edit widget. The think that is confusing, at least it was to me, that in order to make use of this function via the flexviewer editor (at least at V 2.3), you will need to use the function in ArcCatalog to make the attachments fields. The result of this is a related table that stores the attachments, as apposed to having fields directly in the feature table that would hold the attachments (ie with everything else you might have in your attribute table eg. objectid, shape, name, ......).

You might look at this:

Hope that helps,

I too found out that virtual directory was not created in IIS for my arcgisoutput directory. Soon as I made that virtual directory in IIS and made sure the permissions would allow for web access, and it worked!

One thing to note is that my virtual directory is called "arcgisoutput", is pathed to"c:\arcgisserver\arcgisoutput", and it appears as www.fishcda.com/arcgisoutput, however if you look at the actual link that is supplied by rest it looks like the links above (e.g. http://www.fishcda.com/ArcGIS/rest/services/SampleEdit/FeatureServer/3/411/attachments/2). This may lead some to believe that you need to have this crazy long path/nested virtual directories all set up (at least that is what I thought at first look). Apparently, through the magic of ArcGIS Server it translates all this and points the file back to the simple location such as www.fishcda.com\arcgisoutput.

Hope that helps someone,

Thanks Frank,

I followed the steps from http://blogs.esri.com/Dev/blogs/arcg...e-content.aspx
creating attachments to the feature class in the SDE and now I can upload and download attachments to my editable layer.

In my case the virtual directory look good and the IUSR has access, but I'm still getting the error. I was able to see the attachments at one point but now, i get the same error above.
