Clarifications about jta.jar and jboss-j2ee.jar in the Reference Guide - Tutorial --------------------------------------------------------------------------------- Key: HIBERNATE-97 URL: https://issues.jboss.org/browse/HIBERNATE-97 Project: Hibernate Integration Issue Type: Bug Environment: Documentation Reporter: Juraci Paixão Kröhling Assignee: Bawany Satgunanathan In Hibernate_Reference_Guide.pdf , page 17, it lists all the required libraries to run Hibernate. It lists jta.jar file, which is not included in the package with this name. The lib jboss-j2ee.jar, which implements JTA, is included, but the user *may* find it difficult to link jta.jar with jboss-j2ee.jar, considering it is in the "tutorial" part . So, the suggestion is to put a note in the documentation about this, maybe like the note about log4j. Suggestion: Before: more or less libraries. See the README.txt file in the lib/ directory of the Hibernate distribution for more information about required and optional third-party libraries. (Actually, Log4j is not required but preferred by many developers.) After: more or less libraries. See the README.txt file in the lib/ directory of the Hibernate distribution for more information about required and optional third-party libraries. Note: The lib Log4j is not required but preferred by many developers. Note 2:Instead of jta.jar, use your preferred JTA implementation. In the Hibernate distribution, you can use jboss-j2ee.jar for this purpose.
