Introduce smartGWT to an existing GWT project

Hello,

I have created a new GWT project using the maven mojo Archetype. This comes with a default simple GWT project which has a textbox and it does an RPC call with the textbox data.

Added smartGWT to the project, and added the following in the *.gwt.xml

<inherits name="com.smartgwt.SmartGwt"/>
<inherits name="com.smartgwt.tools.SmartGwtTools"/>

Had to add this

<set-configuration-property name='xsiframe.failIfScriptTag' value='FALSE'/>

As the project would not compile.

Deployed the war on tomcat and now the textbox (GWT text box) is not visible anymore.
It looks like smartgwt was not introduced properly to the project. what hav i missed?

Can someone please tell me how i can introduce smartGWT to this simple GWT project?

Will appreciate any help.
GWT version=2.7.0
smartGT=5.0p

Thank you.
