The Enterprise JavaBeans (EJB) 3.0 specification includes an additional persistence specification called the Java Persistence API (JPA). It is an API for creating, removing and querying across lightweight Java objects and can be used both within a compliant EJB 3.0 Container and a standard Java SE 5 environment.

Yes, TopLink Essentials through the pluggable persistence capabilities will function as the persistence provider in an compliant EJB 3.0 container. See similar questions...

Yes, TopLink Essentials offers support for deployment within an EJB 3.0 container or outside the container. This includes using the persistence API in Web Containers, other non-EJB 3.0 Java EE containers, or in Java SE. This allows the persistence API to be used anywhere Java is used.

There is an example on OTN that demonstrates how to call one EJB from another EJB. This example is one session bean calling another session bean but the principles apply globally. In your META-INF directory, add the EJB reference in the application-client.xml file that specifies the EJB you want to refer to. In release 1.0.2.2 we support pessimistic locking and an implicit read-only mode (only changed fields are written. See similar questions...

ejbCreate() is called before the state of the bean is written to the persistence storage (database). After this method is completed, a new record (based on the persistence fields) is created and written. If the Entity EJB is BMP, then this method must contain the code for writing the new record to the persistence storage. ejbPostCreate() is called after the bean has been written to the database and the bean data has been assigned to an EJB object, so when the bean is available.

Monitoring of some environmental indicators take places regularly (for air quality, waste, water and so on). Yes.

There are many differences, all of them should give different type of advantages among the previous 1.1 version. New CMP Model. It is based on a new contract called the abstract persistence schema, that will allow to the container to handle the persistence automatically at runtime. EJB Query Language. It is a sql-based language that will allow the new persistence schema to implement and execute finder methods. Local interfaces. See similar questions...

This issue is a little more complex than it first appears. There are really two categories of class that require deterministic destruction - the first category manipulate unmanaged types directly, whereas the second category manipulate managed types that require deterministic destruction. An example of the first category is a class with an IntPtr member representing an OS file handle. An example of the second category is a class with a System.IO.FileStream member.

The ANX 3.0 tests are two independent clinical tests (or studies) designed to determine the ability of both branches of the autonomic nervous system (ANS) to respond to and relax from a challenge. The two branches that make up the ANS are the sympathetic and parasympathetic (SNS and PSNS, respectively). The challenges are: See similar questions...

CDC is interested in any bugs that users find in CoCASA, and is always working to update and improve the program. These are the known bugs in CoCASA 3.0 and 3.1: When running the "Missing Immunizations" report and looking at PCV7, some children who are complete with 3 doses are being listed as needing a 4th dose.

F@h3.0 is just the new Folding@home client. It is not a whole new project, like the jump from 1.0 to 2.0. The Folding@home website, stats, servers, etc. will not change. The main difference for the Genome@home research effort is that the F@h3.0 client will be able run a new "scientific core" which contains the Genome@home protein design algorithm.
