yes I read the wiki about PMs and there it says the *Fs PM is very fast with
Datastore so I chose it. Can you give some explanation why not to use it ?
Is it the point "If the JVM process is killed the repository might turn
inconsistent" ?
Now to my actual problem... relevant Code frames are :
_________________________________________________________________________
Source code within MDB :
public void createFile(){
try{
...create File here
FileInputStream fin = new FileInputStream(file);
EJB1.persistMeta(fin, nodeID, fileName);
} finally {
jobFinishedSource.fire(new JobFinishedEvent(nodeID,fileID));
}
___________________________________________________________________________
Source code within EJB1
public String persistFile(InputStream in, String nodeID, String
fileName) {
Session session = this.createSession(true);
try {
ValueFactory vf = session.getValueFactory();
Binary bfile = vf.createBinary(in);
Node datasetNode = session.getNode(nodeID);
Property metaProp = datasetNode.setProperty(fileName, bfile);
session.save();
} catch (RepositoryException ex) {
Logger.getLogger(RepositoryBean.class.getName()).log(Level.SEVERE, null,
ex);
} finally {
eventSource.fire(new UpdateEvent(session));
}
}
public Session createSession(boolean writeable) {
Session session = null;
try {
if (writeable) {
session = repository.login(new
SimpleCredentials(UUID.randomUUID().toString(), "".toCharArray()), null);
} else {
session = repository.login();
}
} catch (LoginException ex) {
Logger.getLogger(RepositoryBean.class.getName()).log(Level.SEVERE, null,
ex);
} catch (NoSuchWorkspaceException ex) {
Logger.getLogger(RepositoryBean.class.getName()).log(Level.SEVERE, null,
ex);
} catch (RepositoryException ex) {
Logger.getLogger(RepositoryBean.class.getName()).log(Level.SEVERE, null,
ex);
}
return session;
}
_______________________________________________________________________
Source code within EJB2 :
public void obtainFIle(@Observes JobFinishedEvent event) {
Session session = EJB1.createSession(false);
session.getProperty(nodeID + File.separator + "fileID")
...do some non-jcr stuff here...
session.logout();
}
________________________________________________________________________
One might think I forget to logout of the session in my EJB1.persistmeta but
I put the session into a cdi event. The event is observed by another EJB
(lets call it viewEJB) of which I didn't paste the code but it does nothing
more than update my view and then logout of the session. Normally I wouldn't
put the session into the event but let the viewEJB create its own session
but and thats the same problem I think, when I create my own session in the
viewEJB and try to obtain the changes made they are not visible...
