I really like the cleanness of the JDO model but I am wondering if it would be overkill for what I am designing (e.g. standalone application, no app server, etc).

Sorry I cannot give you an answer, cause I have the same problem... I will add another question: can anybody compare this JDO technology with Apache Torque (Apache DB-project)? Or does anybody know of another open-source solution, that is even better than both of them? In my case most important criteria would be: - is it tested, is it bugfree and can it be considered reliable, for production systems? - how fast is it? feel free to add important criteria to the list...

Hi, I have used with satisfaction the JDO for an embedded web start application and was very satisfied with the results. Eliminates the need for helper code ( perl, JDBC driver, XML - though some configuration requires XML, it is not part of the final application ). Learning curve is a little steep and I would suggest a good book on the subject as there are some undocumented ( by SUN ) tricks, but it is a great tool to have under your belt.

At the other end, for whoever looks for an lightweight solution with small learning curve, no need for extra books etc., torque from apache looks good. JDO is probably somewhere inbetween. I made my personal decision for hibernate, because of the complex transaction management features, scalability and performance I need.

Sure, you may work with multiple handles to the JDX subsystem and have things going on in parallel through them. Each handle would be working with its own ResultSet and the associated JDBC connection. JDX also supports the notion of object-streaming whereby you can go through your ResultSet in a piecemeal fashion (few objects at a time) instead of waiting for a long time and getting overwhelmed with all the (million) objects coming back together. If you are asking for something else, please let me know. -- Damodar http://www.softwaretree.com Quote: On 19 Apr 2004 19:03:23 -0700, [email]dperiwal (AT) softwaretree (DOT) com[/email] (Damodar Periwal) appears to have written: Dave, If you are looking for a simple, flexible, and non-intrusive O/R Mapping product, you may want to check out JDX. With minimal configuration and without the hassles of dealing with multiple XML files, you can get going very quickly. There is no need for an app server to use JDX. It comes with nice GUI tools to simplify configuration and reverse-engineering.

I did not shop around, however, so I don't know how it compares to others.

Dave, I'll admit to being biased, but it sounds like you should take a look at our Berkeley DB Java Edition ([url]http://www.sleepycat.com/products/je.shtml)[/url]. It isn't JDO, it is a transactional database in Java designed to be run from within your application. I think you will find it a perfect fit. -greg _____________________________________________________________________ Gregory Burd Product Manager [email]gburd (AT) sleepycat (DOT) com[/email] Sleepycat Software, Inc. http://www.sleepycat.com/ Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         AppletTalk.com Forum Index -> Java and Databases All times are GMT Page 1 of 1   Jump to: Select a forum Java Newsgroups----------------Java DiscussionsWeb-based java games comp.lang.java 3D Graphics API's for Java Java: Support and criticism Java System Announcements comp.lang.java.api JavaBeans Java and CORBA Java and Databases comp.lang.java.developer Java GUI Toolkits Java Help comp.lang.java.javascript JVM, native methods and hardware comp.lang.java.misc Java Language Programming Security and Java comp.lang.java.setup Java Software Tools comp.lang.java.tech ibm.software.java.linux  Non-English Java Newsgroups----------------Java Language (German)Language Java (Français)Java (Italian)  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
