Re: [TM4J-users] TM4Web/Velocity 0.2rc1 supports Hibernate backends?

[Kal A. <ka...@te...>]

Hi Mathias,

I've checked in some changes for the TM4Web/Velocity package which
provides a basic level of support for listing the topic maps in a
database. You need a configuration like this:

<provider name="hibernate" 
factory="org.tm4j.topicmap.hibernate.TopicMapProviderFactoryImpl">
    <provider-properties>
      <property name="hibernate.connection.url" 
value="jdbc:mysql://localhost/tm4mail"/>
      <property name="hibernate.connection.username" value="***"/>
      <property name="hibernate.connection.password" value="***"/>
      <property name="hibernate.dialect" 
value="net.sf.hibernate.dialect.MySQLDialect"/>
      <property name="hibernate.connection.driver_class" 
value="com.mysql.jdbc.Driver"/>
    </provider-properties>   
    <topicmaps template="topicmap.vm"/>
  </provider>

Note the extra <topicmaps/> element that is required. The template
attribute specifies the template to be used for the main topicmap page.
With this update, you are forced to always use topic.vm to render
topics, but I will work on adding support like you have in the normal
<topicmap> element to specify the template(s) to use to render topics.

In tmbrowse, all topic maps are listed on the index page with their
title as the full base URL of the topic map, so you end up with the URL
listed twice (because by default the index page shows the source URL as
well) - you may want to edit the listmaps.vm template to shorten this.

I hope this gets you the basic functionality you need right now - I'm
going to add a note to the feature tracker on sourceforge so that I
don't forget to finish off this support for the 0.3 release.

Cheers,

Kal
