Re: [JDO] JDO and application server.
Thanks Pedro,
Yes, Currently, I use a single persistance manager for each user. I
create it in the constructor and close it after the session is done.
I will try to create a PM for each job.

users, multiple instances are created and then, it seems that persistent

I think you shouldn't keep an instance of persistence manager for each
user. If you want you may keep a persistence manager factory instead.
I usually create persistence managers, do the job I want with them and
then close them in the end (try - catch - finally {if (pm!= null)
pm.close();}).

Re: Problem setting up OJB using ojb-blank
Hi,
Did you explicitly put in the classpath:
- the directory where find the properties files (repository*,
OJB.properties ...)
- possibly, the directory where you build your classes.
Often, it's a solution to resolve much problems.
Regards,
Alexandre

Re: [JDO] Problem with byte-code enhancement
Ok, I continue to search any solutions.
Which tool you use to enhance byte-code ? (other that JDORI).
I have a case of update that running good with 1..n relation. But I
didn't look further these tests.
Thanks,
Alexandre
Nicolas Arni-Bloch wrote:
I try your class and it work for me.
Just to now. Be careful if you want to use the OJB plugging for JDORI
because it doesn't work very well (or I don't now how to use it).
The 1..n and n..m relation have problem with the persistence by
reachability. When you get object with a query, reachable objects are
load in Transient state (I think) so when you make the commit JDO
make a insert in place of a update.
Here the class (the contentType field those not exit so I change the
code)
public final class CFile {
private long id; // primary-key, autoincrement
private String fileName;
private String contentFile;
protected CFile() {
}
protected CFile(final String fileName, final String contentType,
final InputStream fileStream) {
}
public long getId() {
return id;
}
public String getFileName() {
return fileName;
}
public InputStream getContentFile() {
return (InputStream) new
ByteArrayInputStream(contentFile.getBytes());
}
}
And the CFile.jdo
http://java.sun.com/dtd/jdo_1_0.dtd";>
I make :
java com.sun.jdori.enhancer.Main test/jdo/model/CFile.class
test/jdo/model/CFile.jdo
