Difficulty with the BIRT plugin

Hi, am trying to get the BIRT plugin to work. Firstly: connecting to an odb server doesn't seem to work (incompatible versions) - but there isn't any way to find out what version the BIRT plugin is using. Next: connecting directly to a file datasource seems to work, in the sense that I can ping the database, however, there doesn't appear to be any way to create a new Data Set from the Data Explorer, as suggested in the online manual: #1 2011-07-19 22:23 Hi, am trying to get the BIRT plugin to work.

JPA and handling large data sets

This is not a rellay ObjectDB problem, rather a JPA problem. Our web-based DB supports Hibernate or JPA (ElicpseLink/ObjectDB). We implemented a export/import class to export the whole database or single datasets (domains) in a persistence layer/database independent format. This class works fine - DB exports form a Hibernate/MySQL base via the independent formt to ObjectDB is possible. But exporting large binary data sets is very slow. To avoid memory problems the binary data type is read step by step during the export with the  query/setFirstResult() & setMaxResults().... and using setMaxResults may be fine. If not check if you can retrieve ranges of objects by setting both lower and upper ...

Updating existing persistence entries

I have stored some instances of MyObject via em.persist(myObjectInstance); I can fetch them and bind them to a kind of property editor in my app (it simply calls the setters to reflect gui editing actions). When I try to persist a object later on, I get an error like com.objectdb.o.UserException: Attempt to reuse an existing primary key value which makes sense to me but I'm missing a em.update() method. #1 2012-12-07 19:29 I have stored some instances of MyObject via em.persist(myObjectInstance); I can fetch them and bind them ...

Connecting to a remote objectdb server

I am trying to configure my application in a client-server objectdb setup via tcp/ip. So I first made sure that the remote objectdb server is running using telnet from my local.  $ telnet db.mydomain.com 6136 (worked fine, is able to connect...) My db was configured below: <server>   <connection port="6136" max="100" />   <data path="objectdb://db.mydomain.com/db" /> </server> ... has no permission to create files at that path. Please check also the ObjectDB log file on the server side for errors. ...
