run ant build from web client action

davidheijl

Hey all

how can I realise this user experience:
- working in a space, view a specific file's details.
- i pick an action "publish to …<format>"
- this action runs an ant build target (i have the whole ant side set up and working)

so i guess my question is: how can i run the ant command (do i need to this with java or can i use a javascript with new web scripts)? i know how to add the action to the ui in the webclient, but as from there… any pointers would be welcome!

You will have to use Java to accomplish this.

You have 2 methods of calling Ant, either using the native Ant Java object or calling the Ant script via Runtime.exec(), both of which will need to be done via Java.

I would question why you're using Ant though, it would be preferable to try and do whatever the Ant script is doing in Java as there is going to be a lot of overhead in calling out to Ant.

If you need to however, I'd suggest taking a look at the Ant documentation to see how the Ant process is invoked: http://ant.apache.org/manual/running.html#viajava

hi gavin,

thanks for the reply. I kind of figured this was going to need Java. I spotted an example of someone doing a Runtime.exec() approach elsewhere on the forum, but I'm not entirely sure what the different steps would be.

As for why I want to do this: I'd like to publish DITA xml documents in an Alfresco space using the DITA open toolkit, which is essentially an ant-managed chain of xslt transformations. To rebuild this chain of transformations in Java would be quite a daunting challenge, I fear.

Let's say that I do want to go with the Runtime.exec() approach, what elements would I need to create? could you give me some step by step pointers?

thanks

david

ok, now this is purely because i'm not entirely sure how the whole jsf and beans framework works, but i'm not getting something 😞

let's say i have a bean defined as follows:

<bean id="transformer.dita-xml.eclipse"
class="org.alfresco.repo.content.transform.RuntimeExecutableContentTransformer"
parent="baseContentTransformer">
<property name="transformCommand">
<bean class="org.alfresco.util.exec.RuntimeExec">
<property name="commandMap">
<map>
<entry key="Windows.*">
<value>D:\DITA-OT1.3.1\ant -f build_custom.xml mycompany.mydocument.eclipse</value>
</entry>
</map>
</property>
<property name="errorCodes">
<value>2</value>
</property>
</bean>
</property>
<property name="explicitTransformations">
<list>
<bean class="org.alfresco.repo.content.transform.ContentTransformerRegistry$TransformationKey" >
<constructor-arg><value>text/xml</value></constructor-arg>
<constructor-arg><value>text/xml</value></constructor-arg>
</bean>
</list>
</property>
</bean>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

in which file do i store this code? what else do i need to do to be able to call on this transformation from an action link in the web client?
i have the following custom action set up but obviously there's something wrong with my action-listener code.

<actions>
      <!– Run the DITA OT –>
      <action id="run_DITA_transform">
        <label>Publish DITA to Eclipse</label>
        <image>/images/icons/create_webapp.gif</image>
        <action-listener>#{transformer.dita-xml.eclipse}</action-listener>
      </action>
      
      <action-group id="doc_details_actions">
        <action idref="run_DITA_transform" />
      </action-group>
    </actions>‍‍‍‍‍‍‍‍‍‍‍‍

help!

You actually need to create a custom action not a transformation, see this wiki page on creating a custom action: http://wiki.alfresco.com/wiki/Custom_Actions

The bottom of that page also has a link to http://wiki.alfresco.com/wiki/Custom_Action_UI which will tell you how to add the action to the UI.

thanks gavin! i'll certainly try that - as soon as I get back from my holidays 🙂
