How to set the transformation output file path? [message #47554]

Hello everyone,

I would like my JET transformation output file name to be based on some
variables values.

The current JET code is:

<ws:file template="templates/flow_template.jet"
path="{$org.eclipse.jet.resource.project.name}/flow.xml"/>

I have changed it to:

<ws:file template="templates/flow_template.jet"
path="{$org.eclipse.jet.resource.project.name}/"/><c:get
select="/Flow/@flowName"/>"."<c:get select="/Flow/@flowCategory"/>".xml"/>

where Flow is an Ecore element with flowName and flowCategory attributes.

I would like the output file name to be
<flowName_value>.<flowCategory_value>.xml

When I run my transformation, I get the following error message:
org.eclipse.jet.taglib.JET2TagException: Path must include project and
resource name: /FlowEditor/

Could you please help me to fix this?

Thanks a lot in advance for your time,

Georges

Try:

<ws:file template="templates/flow_template.jet"
path=" {$org.eclipse.jet.resource.project.name}/{/Flow/@flowName}.{ /Flow/@flowCategory}.xml "/>

In general, any JET tag's attribute value can be composed of multiple
'dynamic XPath' expressions between { and }. So, the above ws:file tag has
three expressions in the path attribute:
* $org.eclipse.jet.resource.project.name gives name of the project of the
input model
* /Flow/@flowName and /Flow/@flowCategory give components of the file
name.
