[SOLVED] Webform - Webscript Dynamic Include

[parrym]

I am trying to include a webscript in my webform as suggested here: http://wiki.alfresco.com/wiki/Forms_Authoring_Guide#Using_dynamic_types_in_schemas

But keep getting this error. I have deduced that the web form is finding my web script as it gives a different error if I change to an incorrect path in the include but have no idea what this is supposed to mean:

org.alfresco.web.forms.FormProcessor$ProcessingException: org.alfresco.web.forms.xforms.FormBuilderException: errors parsing schema: at line 23 column 10: A DOCTYPE is not allowed in content. at line -1 column -1: A DOCTYPE is not allowed in content.‍

   <description>My First Webscript - Test to say hello user where user is provided</description>

Help, if any, is much appreciated. Even a working example of including a webscript in a webform would be nice.

Not sure if this will help but here is the server log for a similar example as shown above:

Still can't get it working. I followed the steps here: https://issues.alfresco.com/jira/browse/ETWOTWO-926, namely:

1. We add new property (<prop key="xsd">text/xml</prop>) into "web-scripts-application-context.xml" file
2. Restart Alfresco Server
3. Took files from "WebFormImportingWebScriptTestCase_v2.zip" archive, add all three web script's file into Company Home>Data Dictionary>Web Scripts>org>alfresco>sample space
4. Reload web scripts
5. Create web form based on xsd from archive.
6. Create web project and include created web form into it.

However when I try and use the web form I get this error:

org.alfresco.web.forms.FormProcessor$ProcessingException: org.alfresco.web.forms.xforms.FormBuilderException: errors parsing schema: at line 23 column 10: A DOCTYPE is not allowed in content. at line -1 column -1: A DOCTYPE is not allowed in content.

As usual I have no idea what the error means and am therefore left with nowhere to start.

I may try using an older version of alfresco (Alfresco 2.2 sp4 if i can find it) and let everyone know what I find.

Until then if anyone can tell me why I get this error it would be much appreciated.

Tried the same as above with the files from ETWOTWO-926 and this time Alfresco v 3.0.0 (Stable 1526) schema 1002 and got the following error:

org.alfresco.web.forms.FormProcessor$ProcessingException: org.alfresco.web.forms.xforms.FormBuilderException: errors parsing schema: at line -1 column -1: A DOCTYPE is not allowed in content. at line 19 column 10: A DOCTYPE is not allowed in content.

Update: I still haven't been able to include my own webscript but thanks to Peter Monks Blog Article http://blogs.alfresco.com/wp/pmonks/2009/07/07/including-a-static-xsd-in-a-web-form/ I have managed to include a static xsd file using the alfresco built in webscript /api/path/content{property}/{store_type}/{store_id}/{path}?a={attach?} so I feel I am getting closer.

[parrym]

I'm not sure what the error was but after re-working my files based on pmonks blog entry and removing the javascript file from the webscript and changing storeid={storeid} to ticket={ticket} the dynamic include of a webscript worked!!

[pmonks]

Glad to hear you got it working!

The likely reason it didn't work before is that without the ticket={ticket} parameter the Web Script will be executed without any user credentials.  Due to the bug described at https://issues.alfresco.com/jira/browse/ETHREEOH-1945 this will result in the Web Script failing, and therefore the include will also fail.

Unfortunately the XML Schema specification doesn't treat failed includes / imports as a fatal error, so the Web Form's XSD file will continue being processed until it hits an element defined in the included file, at which point it will fail.  This results in exceedingly unclear error messages, since the reported error is for an element that is typically quite some distance away from the root cause (the failed include / import statement).

The upshot is that as documented at http://wiki.alfresco.com/wiki/Forms_Authoring_Guide#Using_dynamic_types_in_schemas, it is highly recommended that the ticket={ticket} parameter always be included in the URI for a Web Script include.

Cheers,
Peter
