1: yes, by reading the documentation and doing it
2: yes, by either creating your own webapp or changing the jbpm login page/mechanism (it is just j2ee based)
thank u for ur reply.
can u please send me an example project in which you have integrated ur application with jbpm.
and also a document which helps me in that.
please read the existing documentation first (including the wiki), look at the examples and testcases... if you are into java this will give you more than enough information to get started.
