Hi Alexandre, could you send the java class ? wish version of the jdo enhancer do you use ?

Re: [JDO] Problem with byte-code enhancement
Hi Nicolas,
I use the enhancer provided by jdori (com.sun.jdori.enhancer) and
db-ojb-1.0.rc6.
I don't know, because I have a similar class without problem during
enhancement and running.
Here my class file :
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) {
this();
try {
contentFile = IOUtils.toString(fileStream);
} catch (IOException ex) {
ex.printStackTrace();
}
this.fileName = fileName;
this.contentType = contentType;
}
public long getId() {
return id;
}
protected String getContentType() {
return contentType;
}
public String getFileName() {
return fileName;
}
public InputStream getContentFile() {
return (InputStream) new
ByteArrayInputStream(contentFile.getBytes());
}
public String toString() {
return File : id= + id + ; fileName= + fileName + ;
contentType= + contentType;
}
}

Re: [JDO] Problem with byte-code enhancement
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
?xml version=1.0?

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
