You should not share HttpSession; but you can share other objects. For example, you can register an object via JNDI and access the same object in all your apps (databases use this to pool connections).
First of all, it is not possible for foo.com to set a cookie that can be read by bar.com. Host-only only protects example.com cookies from being read by bar.example.com. From RFC 6265 regarding setting a cookie and its Domain attribute: If the domain-attribute is non-empty: If the canonicalized request-host does not domain-match the domain-attribute: Ignore … Read more
I can add my 2 cents from my own experiences (although its more of a compilation of development best practises, you might find it useful to keep them in mind while designing your application): There is no one-size-fits-all design Try to keep application as light weight as possible. Use Maven/Gradle to manage dependencies Don’t rely … Read more
The crucial point IMHO is not the one of features. In that regard, Spring will always be ahead of JavaEE as it’s natural for OpenSource VS. a Standard. So one fact is, that you get the new features much earlier with Spring that with JavaEE (e.g. container integration testing is a new feature in JavaEE … Read more

@ManyToMany to self is rather confusing because the way you’d normally model this differs from the “Hibernate” way. Your problem is you’re missing another collection. Think of it this way – if you’re mapping “author”https://stackoverflow.com/”book” as many-to-many, you need “authors” collection on Book and “books” collection on Author. In this case, your “User” entity represents … Read more
I do not think one can push the user credentials from the browser to the database (and does it makes sense ? I think not) But if you want to use the credentials of the user running Tomcat to connect to SQL Server then you can use Microsoft’s JDBC Driver. Just build your JDBC URL … Read more
