how to use @@ ?

[Alberto Ivo]

hello guys...

I just subscribe the list.. this is my very first post here..

I have a situation here... I would like to know how to substitute some line
code via ant. let me explain better:

In my hibernate.cfg.xml I have the lines:

        <!-- Tomcat -->
        <property
name="connection.datasource">java:/comp/env/jdbc/pmpcDS</property>

        <!-- Weblogic -->
        <property name="connection.datasource">jdbc/pmpcDS</property>

When I'm developing, I use the tomcat datasource and comment the weblogic
datasource, when I generate the WAR to send to the server, I comment the
tomcat line and take the comment ooff the weblogic line..

I would like to know how to automatize this with ant.. I saw that I could
substitute the lines with @@linecode@@ but I didn't find anyplace to learn..


could anyone indicates a good tutorial for that.. or send me a example of
code??


thanks in advance...

If you're doing XML stuff, you could use XMLTask.

Specifically for what you want to do, XMLTask can perform a remove and
uncomment.

Hi Brian,

that seems to be exactly what I want.. But I'm really new to this and didn't
understand how to do it.. for me, that's very complicated. Let me explain my
situation:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

    <session-factory>

        <!-- Configuração Tomcat -->
        <property
name="connection.datasource">java:/comp/env/jdbc/pmpcDS</property>

        <!-- Configuração Weblogic -->
        <!-- <property name="connection.datasource">jdbc/pmpcDS</property>
-->

        ( . . . )

    </session-factory>

</hibernate-configuration>


I didn't understand how i will uncomment the weblogic line and coment the
tomcat line when I generate the WAR. Could you explain me?

Thanks.

So (obviously) you'll need to download the xmltask.jar and reference it thus:

ant -lib xmltask.jar build.xml

(or put it in your Ant lib directory or somewhere on your classpath. The
Ant manual will advise you appropriately).

To do the below, a suitable XMLTask invocation would be:

<xmlcatalog id="dtds">
  <dtd publicId="-//Hibernate/Hibernate Configuration DTD 3.0//EN"
location="A LOCAL COPY OF YOUR DTD"/>
</xmlcatalog>

<target name="uncommentStuff">
 <xmltask source="tomcat.xml" dest="new-tomcat.xml">
  <xmlcatalog refid="dtds"/>
  <remove path="/hibernate-configuration/session-factory/property[1]"/>
  <uncomment path="/hibernate-configuration/session-factory/comment()[3]"/>
 </xmltask>
</target>

Briefly -

The <xmlcatalog> specifies a local copy of your DTD. Otherwise XMLTask
will go across the network to resolve it, and you may not be able to do
that (firewalls etc.)

The <remove> removes the Tomcat property section.

The <uncomment> uncomments the Weblogic section.

It's a bit of a baptism of fire if you're new to Ant. Sorry - hadn't fully
appreciated that when I replied initially...
