Hi there!

I'm trying to use openlaszlo in Liferay bundled tomcat (LR 4.4.0 and  
Tomcat 5.5.25)...

When i deploy the openlaszlo servclet to tomcat and go to http:// 
localhost:8080/openlaszlo-4.0.8-servlet/my-apps/copy-of-hello.lzx

i get the following error:

Error: org.iso_relax.verifier.VerifierConfigurationException: no  
validation engine available for: http://relaxng.org/ns/structure/ 
1.0org.openlaszlo.utils.ChainedException:  
org.iso_relax.verifier.VerifierConfigurationException: no validation  
engine available for: http://relaxng.org/ns/structure/1.0
	at org.openlaszlo.compiler.Parser.validate(Parser.java:732)

I think it is due to some jar incompatibilites...

Is there any way to work around this issue?

Liferay supposedly supports laszlo based portlets, but when i deploy  
the sample portlet, nothing displays... If I try to access the lzx  
file in the portlet, i get the same error as stated above...

thanks a lot for your help!
