[Hibernate-JIRA] Created: (HHH-2998) ZoneAlarm DNS warning when AbstractUUIDGenerator is initialized on Windows Vista

by Moritz Gmelin (JIRA)

ZoneAlarm DNS warning when AbstractUUIDGenerator is initialized on Windows Vista -------------------------------------------------------------------------------- Key: HHH-2998 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2998 Project: Hibernate3 Issue Type: Improvement Components: core Affects Versions: 3.2.5 Environment: Windows Vista with ZoneAlarm Firewall installed, Hibernate 3.2.5 and Java 1.6 Reporter: Moritz Gmelin Priority: Minor When Hibernate initializes the AbstractUUIDGenerator, a call to InetAddress.getLocalHost() is made to get the host's IP address. If the host running the application is a windows vista host with a Zone Alarm firewall installed, the user gets a popup window that the application is trying to a DNS lookup (the DNS lookup is not even executed). This is not a hibernate bug. It is a vista & zone alarm bug. But it would be nice if the call in AbstractUUIDGenerator could be eliminated (the address is just used to generate some unique, random number). From looking at the code, I would guess that repacing the call by calling Math.random() would be just fine.

I had tested to using <key-property> and <many-to-one insert="false" update="false"> instread of <key-many-to-one>, and get no problem for that, so is it the bug on key many to one? The schema and test case is attached. Steps of reproduce the problem with the attached project: ========= 1. Execute the schema.ddl in to mysql db. 2. Execute java application "InsertTestData" 3. Record the last inserted id from the database and modify the "ListTestData" so that the expression value is correct. 4.

[Hibernate-JIRA] Created: (HHH-2522) Cache Provider implementation for IBM WebSphere's dynamic cache

by Joris Kuipers (JIRA)

Cache Provider implementation for IBM WebSphere's dynamic cache --------------------------------------------------------------- Key: HHH-2522 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2522 Project: Hibernate3 Issue Type: New Feature Components: core Affects Versions: 3.2.3 Environment: Hibernate 3.2, IBM WebSphere Application Server version 5.x and 6.x Reporter: Joris Kuipers Priority: Minor Attachments: WebSphereCache.java, WebSphereCacheProvider.java 2nd level cache implementation that uses WebSphere's dynamic cache feature as its backing implementation. Using such an implementation is suggested by IBM in articles like http://www-128.ibm.com/developerworks/websphere/techjournal/0609_alcott/0..., but I couldn't find an existing implementation. Therefore, I wrote my own. I briefly documented the usage in the JavaDoc of the Provider implementation.
