Is it possible to use Hibernate with Annotation without any EJBs. That means, my application contains only Web Project. Where to place the persistence.xml file in the web project.

My constraint is I need to use Annotations. that means all the table-java object mappings should be configured with annotaions and not through configuration files. Only persistence.xml file should be present. In this case where to store the persistence.xml file. If I use EJBs I can place the same in META-INF folder.

Please help.

You put it in the same place as you would with an EJB3 application. The only difference is that rather than the container noticing your persistence.xml and bootstrapping the PU, you must do it yourself. You'll need EntityManager and Annotations. The former is required if you want persistence.xml compatibility. The latter does the binding using annotations. Read the manual:
