<small> Im using liferay 436 .i downloaded quickstart-126.96.36.199(with source) and i have copied this into my ext-tomcat folder . after that from /bede/ext/quickstart-188.8.131.52
Well you are integrating bedework 3.4 to liferay 4.3.
liferay 4.3 is the portal platform.
which uses Servlets , jst168 portlets , struts , hibernate,spring
bedework calendar uses struts as the web ,hibernate as ORM and xslt based view.
You need to learn atleast xslt and portlets to integrate .
you can create a war file which can be deployed on liferay tomcat using the guild line present here
all you need to do is RTFM(google for desc).
and changing the poperties in quickstart sources.
>> <small>Its very urgent for me to integrate bedework with liferay,my client needs it</small>
your can realy go for the built in calendar in the liferay.
Or outsouce your work.
