Added: modules/core/src/java/org/openejb/entity/cmp
CMPEntityInterceptorBuilder.java
InTxCacheInterceptor.java
Log:
GERONIMO-429: Foreign key constraints are not enforced for CMP 2.x EntityBean.
o add a new element to openejb-jar.xml, namely
enforce-foreign-key-constraints,
indicating if DML operations related to CMP EJB need to be sorted in order to
enforce foreign key constraints; and
o add a new Interceptor in charge of defining the InTxCache bound to a
TransactionContext, if require.
