Slawomir, All;

I have encountered another unique error situation with the MDM hLS. My guess is that this happens when everything installed successfully, but eXist is not functioning properly. The service is still live, and is located here:

http://211.73.95.8:8080/geant2-java-xml-ls/services/LookupService

Send a raw query message:

<nmwg:message type="LSQueryRequest" id="msg1" xmlns:nmwg="http://ggf.org/ns/nmwg/base/2.0/"; xmlns:xquery="http://ggf.org/ns/nmwg/tools/org/perfsonar/service/lookup/xquery/1.0/";>

<nmwg:metadata id="meta1">
<xquery:subject id="sub1">
declare namespace nmwg="http://ggf.org/ns/nmwg/base/2.0/";;
/nmwg:store
</xquery:subject>

<nmwg:eventType>http://ggf.org/ns/nmwg/tools/org/perfsonar/service/lookup/xquery/1.0</nmwg:eventType>

</nmwg:metadata>
<nmwg:data metadataIdRef="meta1" id="d1"/>
</nmwg:message>

Get a very strange response (and very long), see the end of this message. I am not sure why the query invokes this response, this may even be an eXist bug, but I do not think that the return message should be sending a 'success.ls.query' status. I am going to handle this at the API level, but I there should be some error checking on the service side to prevent this from leaking into the response.

Thanks;

-jason

<a name="overview"></a>Overview</h1>

<p>eXist-db is an open source database management system entirely built on XML
technology. It stores XML data according to the XML data model and features
efficient, <a href="http://www.w3.org/TR/xquery/">index-based XQuery</a> processing.</p>

<p>eXist-db supports many (<a href="http://en.wikipedia.org/wiki/Web_2">web</a>)
technology standards making it an excellent application platform: <blockquote>
<ul>

<li>
<a href="http://www.w3.org/TR/xquery/">XQuery 1.0</a> / <a href="http://www.w3.org/TR/xpath20/">XPath 2.0</a>
</li>

<li>
<a href="http://www.w3.org/TR/xslt">XSLT 1.0</a> (using Apache Xalan) or <a href="http://www.w3.org/TR/xslt20">XSLT 2.0</a> (optional using <a href="http://saxon.sourceforge.net/">Saxon</a>)</li>

<li>HTTP interfaces: <a href="http://en.wikipedia.org/wiki/Representational_State_Transfer">REST</a>, <a href="http://www.webdav.org/">WebDAV</a>, <a href="http://www.w3.org/TR/soap/">SOAP</a>, <a href="http://en.wikipedia.org/wiki/XML-RPC">XMLRPC</a>, <a href="http://en.wikipedia.org/wiki/Atom_(standard)">Atom Publishing
Protocol</a>
</li>

<li>XML database specific: XMLDB, XQJ/<a href="http://jcp.org/en/jsr/detail?id=225">JSR-225</a> (under
development), <a href="http://xmldb-org.sourceforge.net/xupdate/">XUpdate</a>,
XQuery <a href="update_ext.xml">update extensions</a> (to be aligned with the new
<a href="http://www.w3.org/TR/xquery-update-10/">XQuery Update Facility 1.0</a>

</li>

</ul>
</blockquote>

</p>

<p>eXist-db is highly compliant with the <a href="http://www.w3.org/TR/xquery/">XQuery</a> standard (current <a href="http://www.w3.org/XML/Query/test-suite/">XQTS</a> score is <a href="http://www.w3.org/XML/Query/test-suite/XQTSReportSimple.html">99.4%</a>).
The query engine is highly extensible and features a large collection of XQuery
Function Modules.</p>

<p>eXist-db provides a powerful environment for the development of web applications
based on XQuery and related standards. Entire web applications can be written in
XQuery, using XSLT, XHTML, CSS and Javascript (for AJAX functionality). XQuery
server pages can be executed from the filesystem or stored in the database.</p>
