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

[Mathias R. <mat...@we...>]

Hello,

I'm stuck with setting up TM4Web/Velocity 0.2rc1 with a hibernate
backend.
Configuration is
  <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>   
  </provider>

I don't get any errors but I don't get any TopicMaps from by backend 
either. In stdout.log it says
"topicmaps element ignored for provider 'hibernate' which is not in-memory."

Do I miss something or is Hibernate support currently not available with 
TM4Web/Velocity?

Thanks,
Mathias

Hi Mathias,

TM4Web/Velocity does support the Hibernate backend, but the <topicmaps>
element is only provided for loading topic maps from a file-system
directory (so its only used with the in-memory backend). You have to
configure each topic map you want displayed separately. It would
probably be nice if there was an option to list either all of the topic
maps in the database or some subset (e.g. by matching the baseLocator
against a regular expression). I'll look into adding something like that
for 0.3.

Cheers,

Kal

Hi Mathias,

I tracked down the error in the TM4Web/Velocity source. I've checked a
fix for this into CVS - so it will be part of the 0.2 release.

If you are happy to grab the file from CVS and build it yourself thats
cool. If you would like a compiled version of the JAR file, email me
privately and I'll send it to you.

Cheers and thanks for the bug report!

Hi Mathias,

I'm afraid that I don't have a release plan at the moment - I'm trying 
to get TMAPI 1.0 and TM4J 1.0 finished over the next week or so. If I 
can get a bit of time (and I might have some time this weekend), I'll 
take a look at implementing this - I just can't promise anything right 
now. I'll keep your need in mind though!

Cheers,

Kal

[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
