Does anyone know a good open-source project where I could have a look on the persistence layer (for good programming practices and transaction management) where Hibernate 3 and JPA 1 is used?
I couldn't tell you of any open source projects you can check out, but if you want to learn hibernate I can recommend a great book from Apress. It is called Hibernate Recipes and it pretty much explains everything.
PS: no kind of advertising intended, just trying to help OP.
Try to search Bitbucket or GitHub repositories for "Hibernate", you will find a lot of sample projects you can learn best practices from.

I am working on a web project using velocity template and servlets. The code is a bit old and we are trying to refactor it before adding new functionalities. I am thinking of introducing dependency injection framework. Searching on net, I found spring DI, pico, guice as some of the options. But, not sure which is the right option. Ideally, I am looking for something easy to start with and lightweight.
Considering it is "a web project using velocity template and servlets", I suggest springframework. It is well documented, vastly used/tested, active community and will help with more then DI.

i need to use an ERD tool in eclipse, to make ERD diagrams for my database tables
and can generate hibernate classes, please suggest me a good eclipse plugin if there's any.
One of the well known and used ones is http://eclipse-erd.sourceforge.net/
Another good one is http://dbva-for-eclipse-for-windows.visual-paradigm-international-ltd.crystal-product.com/
Note that most of such plugins are NOT free.
What I do is to create object class diagram with hibernate annotations.
You can either type the annotation manually in the code and get them immediately updated in your diagram or you can add hibernate stereotypes and got them in the code. It works in both directions.
This is a good alternative to traditional ERD and a lot more powerful approach.

How you do design composite webservices. Are there any frameworks available to let the developer simply concentrate on bussiness logic and to implement composite frameworks with some simple configuration.
I have read about SCA. But seems there is very less implementations of it.
Can some one suggest are there any frameworks which support ease of developing the composite webservices
An ESB caters this aspect to some extent. Please have a look at the open source WSO2 ESB built on top of Apache Synapse.
The WSO2 ESB comes with a large number of samples and please have a look at this sample too....
Thanks...

I know the question is subjective, but since the OpenID libraries page lists a number of libraries, I thought some attempts might be made to nominate one or two that are best, in terms of:
project activity
quality (few bugs, easy API, properly implementing the protocol)
documentation
I'd appreciate an answer from anyone having used any OpenID Java library
My choice was openid4java, because:
it is in a public maven repository
it's been actively developed (see the activity indicator on google code)
it worked fine, with the documentation provided
it's easy to use

Please suggest some tutorial/cheatsheet for learning pointcut expression.
The AspectJ programmers guide has plenty examples, looks straightforward.
AspectJ in Action is also a great source of information on AOP and AspectJ.
Spring.Net has excellent documentation which can be downloaded from here: http://www.springframework.net/documentation.html
It has a very good general introduction to AOP and examples and sample AOP programs to get you started. Not knowing much about AOP, but knowing a bit about Spring.Net, I found this enough to get an AOP-based logging system up and running.
