Unable to determine root cause for com.tridion.util.TCMURI ClassNotFoundException

Question

I have already included Tridion.ContentDelivery.dll in the bin folder with a Reference in Web.config

<add tagPrefix="tridion" namespace="Tridion.ContentDelivery.Web.UI"
     assembly="Tridion.ContentDelivery"/>

Even with this reference, when rendering a Component Link in my .NET Application I get a ClassNotFoundException. Can anybody help me to determine root cause for this?

com.tridion.util.TCMURI

Answer 1

It looks like you're missing a JAVA class, not a .NET class.

I'd recommend finding your Tridion installation files, search for [Install]\Content Delivery\roles\preview\web\dotNet\webapp folder, then compare your web application to either the x86.zip or x86_64.zip pre-built webapps.

Chances are you're missing a couple of jars.
