How to make new RuntimeExecutableContentTransformer visible?

Hi,I've created a new -context.xml file that registers a new RuntimeExecutableContentTransformer for mimetype application/acp -> application/zip. However, the wiki is very fuzzy regarding how to make this visible to the end user on the web client. Does anyone have experience or insight that the

I think as long as you've registered the transformer bean you're good. Here's an example from the Alfresco Developer Guide that registers a Microsoft Project to Plain Text transformer:

<bean id="transformer.Project"
         class="com.someco.transformer.ProjectToPlainText"
         parent="baseContentTransformer" />‍‍‍

The transformer should be invoked properly when you run one of the "transform content" actions against a document that matches the mime type for which the transformer is registered.

You don't invoke a transformer directly–you tell Alfresco, "Here is a PNG file. I want this as a PDF," and Alfresco figures out which transformer can do that, then runs it.

Hey Jeff,

Thanks for your reply. I've actually read a good portion of your guide, and I tried to refer to that section for my purposes, but I don't think it applies directly. I'm using the org.alfresco.repo.content.transform.RuntimeExecutableContentTransformer class to call a script on the server to run the transformation, and I've written a *-context.xml file that configures a bean "transformer.dita.PDF". I turned on debugging so I can see Alfresco registering my transformation as it loads. However, when I go to Run Action -> Transform and Copy Content to a Specific Space -> Set Values, there is no option to transform to a Zip file.

So, do you (or anyone else) know of a way to set the mime types that show up in that list or am I going about it from the wrong direction? I think I might need to create a new Action to run the transformation. If anyone has a better thought there, I'm open to suggestions.

Thanks

Rich,

There's a list of transformers in web-client-config.xml:

 
     <!– The list of transformers to show in the transform actions –>
     <transformers>
         <transformer name="application/vnd.oasis.opendocument.text"/>
         <transformer name="application/vnd.oasis.opendocument.presentation"/>
         <transformer name="application/vnd.oasis.opendocument.spreadsheet"/>
         <transformer name="application/rtf"/>
         <transformer name="text/html"/>
         <transformer name="application/pdf"/>
         <transformer name="text/plain"/>
         <transformer name="text/xml"/>
         <transformer name="application/x-shockwave-flash"/>
         <transformer name="image/gif"/>
         <transformer name="image/jpeg"/>
         <transformer name="application/msword"/>
         <transformer name="application/vnd.excel"/>
         <transformer name="application/vnd.powerpoint"/>
      </transformers>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Have you tried extending this list?

No, I hadn't, but that was exactly what I was looking for. I'm having to rethink the problem now though because my solution didn't work out the way I thought it would. Anyway, thanks for your help, Jeff – I have a better understanding of Alfresco after working on this problem.

Also, good work on the DoCASU interface. It's very simple and fast, which is what I think most users would prefer.

Sorry, but can you write your *-context.xml where you've extended your X -> application/zip transformer ?

I' ve some, but unfortunately it won't work. Alfresco cannot find my transformer, it replaces by it's default one.
source mimetype: text/plain
target mimetype: application/zip
transformers: []
