Q&A

Q1:

Where can I get a resource adapter to use with WebLogic Server?

A1:

You can obtain a simple RA for development use from the J2EE Connector Architecture home page at the http://java.sun.com/j2ee/connector/index.html.

These RAs, called the black box adapters, are simple wrappers over the JDBC API and can be used with any relational database. Depending on the transaction level supported by the relational database, you should use the relevant RA. The list of black box RAs for a specific transaction level is given in Table 21.1.

Table 21.1. Black box RAs

Resource adapter	Transaction level supported
blackbox-notx.rar	No transaction
blackbox-tx.rar	Local transactions
blackbox-xa.rar	JTA XA-based transactions
cciblackbox-tx.rar	Local transactions
cciblackbox-xa.rar	JTA XA-based transactions

Q2:

Which application server vendors and EIS vendors support the JCA specification?

A2:

The complete list of application server vendors and EIS vendors that conform to the JCA specification can be accessed at http://java.sun.com/j2ee/connector/products.html.
