Deploying Web Appbuilder app

Mehretab — Tue, 13 Jun 2017 15:28:49 GMT

I have been developing an app from the developer edition of web appbuilder and deployed it in our Web server (Tomcat) it seems to work with out any problem from our organizations intranet and internet infrastracture. But when we tried it at home from our own machine it appears to hang forever with the blue sreen (loading screen). Here are the error report from the console of chrome and Firefox.

From Chrome (2 error report)

Failed to load resource: the server responded with a status of statisticsUtils.js 403 (Forbidden)

js.arcgis.com/3.20/init.js:3Error: scriptError at f (js.arcgis.com/3.20/init.js:10) at HTMLScriptElement.<anonymous> (js.arcgis.com/3.20/init.js:35)

from Firefox

Request URL: http://myDomain/MyApp/jimu.js/statisticsUtils.js

Status Code 403 Forbiden

It complains about the statisticsUtil.js file and this javascript file resides in the Jimu.js folder and it deals with query and filtering a layer (from my understanding), this file is the only file which can not be opened from the browser and it throws this error message (403 Forbidden: You don't have permission to access /...../..../jimu.js/statisticsUtils.js on this server). Any idea Robert Scheitlin, GISP and any body that have an idea what did I do wrong in the process of deploying the app.

Thanks in advance

Mehretab,

I am not very familiar with Tomcat but it sounds like a permissions issue. Are you adding the WAB app files to the webapps folder in your Tomcat deployment?

I hope by now you are awake and thanks for the reply. Yes my WAB app files are in the webapps folder. My services are publicly shared in portal and I have ofcourse an esri base map. My question is Is it necessary/must to set a proxy? The mystery for me is it works fine in my offices browsers but not if I want to access it at home form my machine. Are they extra steps in the deployment that deals with permission issues?

Mehretab,

No a Proxy is only necessary when using secured services or wanting to use services that require credits on AGOL or geometry service operations that need to use POST instead of PUT. There is no extra steps dealing with permissions that I am aware of.

Robert,

It would be interesting to try it on IIS server to see if the Tomcat deployment process is the problem. Do you know some free providers.

Mehretab,

If you are using MS Windows OS then you have free access to IIS.

Robert,

yes you are right but unfortunately our organisation disabled it.

So you just go to control panel > Programs and Features > Turn Windows features on or off > Internet Information Services and add it.

If their IT/administrators give them the ability to do that (our blocks it for us now).

Mehretab Tquabo Sium Is it a public web site that you can share? That way others can test browsers they have since it may be something that is blocked by your home browser.

Otherwise, I agree with Robert that is something that is being blocked by Tomcat, possibly external permission access to "/...../..../jimu.js/statisticsUtils.js" ?? My guess is you modified the path, but if not, maybe it doesn't recognize the path (just guessing here. I haven't used Tomcat for a long time either)

Mehretab...we deploy our apps from WAB Developer to IIS; however, we have to modify the env.js file for each app to call out the proper URL for the Esri JavaScript API once published to IIS. On line 61 of the file, I change the string...

FROM:

apiUrl = null,‍‍

TO:

apiUrl = '//js.arcgis.com/3.19',‍‍‍‍

Brian,

That is really strange and uncommon that you have to manually do that. I have never had to.

Re: Deploying Web Appbuilder app

BrianCollins — Wed, 14 Jun 2017 21:01:45 GMT

Not sure what to make of the root cause, but that's our workaround. I just tested and confirmed that it occurs in all our apps, including newly created ones after we upgraded to 2.4 and it does. At any rate, that's our fix and we'll stick to it. I suppose I could fix the root env.js file in the stemapp directory to save time modifying each new app in the future.

Thanks again Robert Scheitlin, GISP, Rebecca Strauch, GISP and Brian Collins sorry for not replaying on time, I was out of office. I tried as Brain suggested and it didn't workout for me and I also deployed an app created in WAB 2.2 to see if the isue is only in 2.4, but the issue seems identical. Here is the link to the web site so that you can have a firt hand impression to the Error messages. Thanks again.

Mehretab,

Try and copy the statisticsUtils.js from your WAB dev stem app folder and replace the one in your websites jimu.js folder with it and test again. It could be that the file got corrupted somehow.

Hello,

Im experiencing the same issue ,when I try to bring in a custom widget from web app builder 2.7 into Portal 10.5

and the error looks like this

 Error: scriptError
 at f (init.js:10)
 at HTMLScriptElement.<anonymous> (init.js:35)

This is the error message , Would anybody that may have faced this issue let me know a solution or work around.

We are using Windows IIS

BPriya,

Portal 10.5 is WAB Version 2.4 (I think) so you will have a problem using a 2.7 WAB custom widget that is using djits and components that might not have existed in WAB 2.4.

I was able to bring in the Public notification widget ,but unable to being in the screaming widget ,Any idea why or how It worked the first time

Also ,curious to know if there is way to update the version from 2.4 on portal 10.5.1

Re: Deploying Web Appbuilder app

RobertScheitlin__GISP — Wed, 25 Jul 2018 21:03:27 GMT

BPriya,

No it is not possible to update Portal to a different version of WAB. This would void all support by esri. The screening widget is just not compatible with your version of WAB. Portal 10.6.1 is out now in the US so you should upgrade as soon as possible.

Hello Robert,

Thanks for the quick reply ,As it turns out that 2.8 will not work for 10.5.1 ,we will have to wait until our organization decides to upgrade.
