:docid Problem

X-Application Version: 4.1.1
Tamino Version : 4.1.1
Platform : Win2k
WebContainer : Tomcat 4.1.1
JDK Version : 1.4.1



Hi,

with Tamino X-Application 3.1.1, it was possible to access a document via a URL providing a Tamino Query via the :docid parameter (e.g. …/modify.jsp?:action=modify&:docid=/Doctype[Node%3D’Value’]). -->> Trying this with 4.1.1 leads to an error “PreconditionViolation”.

The error message is : format must be ‘[…]’, but was ‘/Doctype[Node=‘Value’]’

Is it no longer possible to issue queries against Tamino using the :docid parameter containing the query string ?

Calling modify.jsp within the X-Application (out of the view.jsp page), there is indeed a format used with (at least in my case) 6 parameters inside of the brackets.

Kind regards,

Hello,

With the support of Tamino 4.1.x the docid was not longer sufficient to get access to a document because documents can by a sub-tree of document identified by a node id. Therefore, the internal parameter “:docid” becomes more complex, it is a vector of doctype, inoid, nodeid and collection.

I propose not to use internal parameters to get access to an X-Application. Instead, I would use a JSP page that handles this access. For example:

If you have an XQuery to load a document and you want to edit this document via a generated “modify” page of X-Application, use the following approach.


Build a JSP page modifyMyDopcument.jsp. Use a tag xapp:directcommand to load the document and set the modify state.

<xapp:module>
  <directcommand type="read" document="...Document" schema="myDocSchema" collection="myCollection" arg="${myQuery$}" />
  <directcommand type="modify" document="...Document" />
</xapp:module>
<%
  pageContext.forward("modify.jsp");
%>
</pre><BR><BR>The attribute 'document' depends on the attribute 'document' of your 'modify.jsp' page. Use the same value as the attribute 'document' of xapp:form tag has.<BR><BR>The values of the attributes 'schema' and 'collection' depend your application. Have a look into the generated page 'search.jsp' which values are used for 'schema' and 'collection' within the tag 'xapp:action type='xquery'.<BR><BR>The invocation of your page could look as follows:<BR><BR><pre class="ip-ubbcode-code-pre">
http://localhost:8080/myApplication/modifyMyDocument.jsp?myQuery=for $x in ... return $x
