Invalid URL on otherwise valid eXist queries

I could simplify parts of my application, hopefully improve performance a bit if I
could use the same URL's as an instance src attribute as I do on a browser address.

For example, enter the following in the browser and I get the

http://db.nees.ucsb.edu/exist/rest?_query=doc('/pub/sitechan.xml')//sitechan[sta='GVDA'][matches(chan,'^H')]

and I get the particular subset I need. The browser translates the url to this:

http://db.nees.ucsb.edu/exist/rest?_query=doc%28%27/pub/sitechan.xml%27%29//sitechan[sta=%27GVDA%27][matches%28chan,%27^H%27%29]

However, the same url, translated or not, cannot be used as an instance src attribute:

<xforms:instance id="gvda-sitechans"
src="http://db.nees.ucsb.edu/exist/rest?_query=doc%28%27/pub/sitechan.xml%27%29//sitechan[sta=%27GVDA%27][matches%28chan,%27i^H%27%29]"
xxforms:readonly="true"/>

java.lang.IllegalArgumentException Exception Class java.lang.IllegalArgumentException Message Invalid uri 'http://db.nees.ucsb.edu/exist/rest?_query=doc('/pub/sitechan.xml')//sitechan[sta='GVDA']': Invalid query Servlet Stack Trace
(119 method calls)
Class Name Method Name File Name Line Number
org.apache.commons.httpclient.HttpMethodBase <init> HttpMethodBase.java 222
org.apache.commons.httpclient.methods.GetMethod <init> GetMethod.java 89
org.orbeon.oxf.resources.handler.HTTPURLConnection setRequestMethod HTTPURLConnection.java 78

Is there a way to avoid url checking? Looks like it's part of the apache commons, but
it seems to me this behavior is recent, within the last year.

Thanks,
Hank

Hank,

I am wondering if you get this exception HttpClient exception because
it wants more characters (such as the brackets) to be encoded. I use
the _query =... trick a lot, and often use it with encode-for-uri().
E.g.:

<xforms:submission method="get" action="...?_query={encode-for-uri
(...)}"/>

You can't use an AVT in <xforms:instance src="...">, but you can run a
submission on xforms-model-construct-done and put the oxfords:readonly
on that submission.

Indeed that is the issue. Unfortunately for XPath, square brackets are part of the
IP 6 URL specification, but UTF-8 encoding works around this (for now).

Thanks. It seems a bit counter-intuitive to initialize an instance on the
xforms-model-construct-done, but if that works...

Wind back in the sails, thanks,

Re: Invalid URL on otherwise valid eXist queries

In reply to this post by Alessandro Vernet

I am using square brackets as a predicate in an eXist xquery which works bu fails in submission from xForms because of the square bracket. I found this post but maybe I do not understand something because using encode-for-uri does not do anything. Here is my submission:

<xforms:submission id="psiSearch" method="get"
action="http://localhost:8600/exist/rest/db/?_query=declare namespace xmldb='http://exist-db.org/xquery/xmldb';
let $resources := for $x in xmldb:get-child-resources('/db/CJPSIS/completedPSI')[contains(., '000000029098')]
return <file>{{$x}}</file>
return <files>{{$resources}}</files>"
replace="instance" instance="searchResults" xxforms:username="XXXX" xxforms:password="XXXXXX!" validate="false">

<xforms:message ev:event="xforms-submit-error" level="modal">exist call failed</xforms:message>

</xforms:submission>

How do I escape the square brackets above for the predicate? Thank you.

Re: Invalid URL on otherwise valid eXist queries

I used a different query to (where clause) instead if the predicate. The predicate is more efficient so I would still like to know the solution, but it is no longer an urgent matter. He is the new xquery:

<xforms:submission id="psiSearch" method="get"
action="http://localhost:8600/exist/rest/db/?_query=declare namespace xmldb='http://exist-db.org/xquery/xmldb'; declare namespace fe='http://york.com/forms/probation/xform'; let $resources := for $x in xmldb:get-child-resources('CJPSIS/completedPSI') where starts-with($x, '{instance('search')/fe:offenderID}') return <file>{{$x}}</file> return <files>{{$resources}}</files>"
replace="instance" instance="searchResults" xxforms:username="XXXX" xxforms:password="XXXXX!" validate="false">
<xforms:message ev:event="xforms-submit-error" level="modal">exist call failed</xforms:message>
</xforms:submission>

I cannot confirm that url-encode will encode square brackets. I was using
the query on an instance src= attribute. Manually encoding the brackets
corrected the problem.
