EJB Considerations
These EJB considerations apply to both zSeries and i5series platforms.
- Transaction Attribute for session EJBs:
- The transaction(TX) attribute must be specified for all the session EJB methods. In some environments you can specify TX attributes for only some Session EJB methods, however, the zSeries environment does not support some methods being mapped and others not. In virtual member manager, all unspecified methods are supported by default.
- JNDI lookup for EJB and locating DataSource:
- java:comp/env/ must be prefixed while performing a JNDI lookup for an EJB or a DataSource.
