Access Remote Orbeon server

[Sanjana Vanjinathan]

Alex,

I would like to connect Orbeon server which is running on different tomcat , (remote server)

From my local application to connect remote server I am getting 404 error.

Regards,

Vanji

Hi Vanji,

Could you describe your setup in more detail and provide more information about the error you are encountering, including a screenshot of the error and attaching your `orbeon.log`?

Hi Vanji,

The servlet utilizes a `RequestDispatcher` for communication with Orbeon Forms, which necessitates both your application and Orbeon Forms to be hosted on the same instance of Tomcat. This requirement explains the error message you encountered:

    Can't find Orbeon Forms context called '/orbeon'. Check the 'oxf.xforms.renderer.context' filter initialization parameter and the <Context crossContext='true'/> attribute.

Unlike the above setup, the Form Runner embedding API does not share this limitation. It enables the embedding of a form, created with Form Builder, into a Java web application running on a different server (i.e., a different JVM or host). However, to utilize this API, the form definition must reside on the Orbeon Forms side. This means your application cannot generate the form definition and then pass it to Orbeon Forms. Please confirm if this explanation is clear.
