[Hibernate-JIRA] Created: (EJB-252) Persistence.xml <class> entity does not allow package name to be specified (documentation says it does)

by Kenneth Roe (JIRA)

Persistence.xml <class> entity does not allow package name to be specified (documentation says it does) ------------------------------------------------------------------------------------------------------- Key: EJB-252 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-252 Project: Hibernate Entity Manager Type: Bug Components: EntityManager Versions: 3.2.0.ga Environment: 3.2.0, Oracle 9i r2 Reporter: Kenneth Roe The EntityManager reference documentation indicates that you can specify a package name in the <class> element of persistence.xml. This does not appear to be the case. Section of the documentation that says package names will work: "The class element specifies a fully qualified class name that you will map. By default all properly annotated classes and all hbm.xml files found inside the archive are added to the persistence unit configuration. You can add some external entity through the class element though. As an extension to the specification, you can add a package name in the <class> element (eg <class>org.hibernate.eg</class>)." -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-2290) Using a composite-element in a set creates invalid SQL on Oracle if composite-element has a CLOB field

by Frank Durden (JIRA)

Using a composite-element in a set creates invalid SQL on Oracle if composite-element has a CLOB field ------------------------------------------------------------------------------------------------------ Key: HHH-2290 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2290 Project: Hibernate3 Type: Bug Versions: 3.2.1 Environment: Oracle, version: Oracle9i Enterprise Edition Release 9.2.0.7.0 Reporter: Frank Durden Attachments: test-case.jar Hi, With a mapping like the one below I get an "ORA-00932: inconsistent datatypes: expected - got CLOB" if I remove or modify a ChildElement: When Hibernate tries to remove the ChildElement it generates SQL like "delete from TEST_CHILDREN where PARENT_ID=? and NAME=? and VALUE=?". It is not possible in Oracle to use the equal sign with CLOB fields. Test case attached. A workaround is to use a stored procedure to delete the ChildElement using a "<sql-update callable="true">", but this works only as long as the CLOB field is <32k. With values bigger than 32k you get an "ORA-01460: unimplemented or unreasonable conversion requested", at least with an OCI driver. Anyway, it is quite inefficient to pass huge CLOB fields as arguments on delete operations. The ultimate solution in my mind would be to have a property tag specifying that the property should not be used in delete operations. <hibernate-mapping> <class name="com.test.Parent" table="TEST_PARENT"> <id name="identifier" type="long" unsaved-value="0" column="ID" > <generator class="sequence"> <param name="sequence">test_seq</param> </generator> </id> <version name="version" type="long" unsaved-value="negative" column="VERSION"/> <property name="name" column="NAME" type="string"/> <set name="children" lazy="true" table="TEST_CHILDREN" cascade="all,delete-orphan"> <key column="PARENT_ID" not-null="true"/> <composite-element class="com.test.ChildElement"> <property name="name" column="NAME" type="string"/> <property name="value" column="VALUE" type="text"/> </composite-element> </set> </class> </hibernate-mapping> -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Resolved: (ANN-395) @Embedded can not map interface

by Emmanuel Bernard (JIRA)

The problem seems to be in AbstractStatementExecutor. It seems to assume that if a DDL statement, in general, results in a commit that this will also happen for a temporary table. In the case of MySQL, at least, this is not the case. The code in AbstractStatementExecutor goes and creates the temporary table in a new connection, which, in the case of MySQL, will not be visible in the current transaction. http://fisheye.jboss.com/browse/Hibernate/branches/Branch_3_2/Hibernate3/... -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
