Hi Rüdiger,
long time ago you answered my request "Sorting of elements with
cms:contentload".
But not until today we tried to realize your proposal. And we encountered
some problems:
We wrote our own ResourceCollector by using
org.opencms.file.collectors.CmsDefaultResourceCollector as template for
our own,
we added an additional parameter "companySort" to this collector,
indicating the column we like to sort.
and we copied the class into the class directory of the module:
/system/modules/org.vug.templates/classes/org/vug/templates/
We added a line in the collectors-node of the opencms-vfs.xml.
<collectors>
<collector class="org.vug.templates.CmsVaterResourceCollector"
order="90"/>
<collector
class="org.opencms.file.collectors.CmsPriorityResourceCollector"
order="100"/>
<collector
class="org.opencms.file.collectors.CmsDefaultResourceCollector"
order="110"/>
<collector class="org.opencms.file.collectors.CmsDateResourceCollector"
order="120"/>
<collector
class="org.opencms.file.collectors.CmsTimeFrameCategoryCollector"
order="130"/>
<collector
class="org.opencms.file.collectors.CmsCategoryResourceCollector"
order="140"/>
</collectors>
We added the collector "companySort" in the jsp, that creates the list:
<cms:contentload collector="companySort"
param="/inside/telefonliste/mitarbeiter/*.html|maentry"
editable="false">
We wanted to test the result but somehow the jsp cannot find the new
class, we received an error-message:
javax.servlet.jsp.JspException: org.opencms.main.CmsException: Collector
"companySort" was not found.
Der Grund: Collector "companySort" wurde nicht gefunden.
Do you have an idea which step is missing in order for the
contentload-command to trigger the new collector-class?
It seems that it does not even enter the new class; how is the new
"companySort"-collector linked to the new collector-class. Is there
another xsd or xml, that needs to be amended?
Thank you in advance for your kind support.

Frank,
it is possible to write your own ResourceCollector by extending the
abstract class A_CmsResourceCollector. You can use the class
org.opencms.file.collectors.CmsDefaultResourceCollector as template for
your individual collector. add an additional parameter to this collector
which indicates the column you want to search for.
Don't forget to add the new Collector into the <collectors> node of the
file opencms-vfs.xml.
For Implementation you need a comparator which compares the content of
your XML Content. For performance reasons I would recommend you to map
the Company name and the Location on a property because unmarshaling of
XML contents is an expensive Task and very complicated.
good luck ...
