Guestbook EE ear app please

Using Eclipse I have no problems running the Guestbook app as a web app on an EE 6 server. However, I would like to call the ejb from a remote client. I have tried various ways in creating different projects for ejb, web and client, with and without an ear, and bump into queer problems. Of course I have a remote (and local) interface, but I can't get anything to run unless I do EXACTLY one web project as in your tutorial. Can you please put together another tutorial illustrating remote client access along with web access. #1 2014-10-19 18:24 Using Eclipse I have no problems running the Guestbook app as a web app on an EE 6 server.

Embedded in JDO metadata not working in objectDB 2.x ?

Hi, I am using JDO access to the database with the persistence defined in package.jdo XML metadata files. In those metadata files I have few persistence-capable classes which had extents in ObjectDB 1 (with an OID for every instance) and all other classes were embedded (so without extent and own OID) in those few peristence-capable ones. Example of JDO metadata: #1 2014-07-04 16:48 Hi, I am using JDO access to the database with the persistence defined in package.jdo XML metadata files. ...

Queries are slow on a large database

Hi, I have a 12GB database with 787603 entries. It is much larger than usual and there are performances issues. I am doing small queries and they take much longer than I expect, i.e.: Get the total number of entries Get 25 consecutive entries (i.e. 0-25) Get one specific entry On average each query needs 4 to 5 minutes to return a result. I have been adviced to use indexes but they are already used through the JDO Metadata file. For instance I use this class: #1 2014-05-28 13:05 Hi, I have a 12GB database with 787603 entries.

Eclipse plugin problem (using ObjectDB as a separate bundle)

Hello support, I have seen multiple attempts to correct similar errors as in the title above - the latest in the 2.2.8.01 release of objectDb. However I still get this error.   Here is my scenario (Groovy 1.8 and Eclipse 3.6) used. I have a com.epimss.lab.data.toxicology.TherapeauticDrugScreenRqst. Nested in this class are the following two classes: com.epimss.lab.data.misc.OtherRqst and com.epimss.lab.data.misc.RequestDateAndNumber. #1 2011-07-11 15:49 Hello support, I have seen multiple attempts to correct similar errors as in the title above - the latest ...

Explorer in 2.3

First, the new Explorer in ObjectDB is fantastic! This is exactly what we've needed - an easy way to do ad-hoc JPQL queries and navigate through the results and even make small changes to primitive data and Strings. After playing with it for a while, here is a list of additional features I'd love to have: 1. Export of selected data: a. Simple - Select a range of cells or a column header and copy text to the clipboard or save to a file (csv, html, etc..). (There appear to be copy menu options, but I cannot get them to work.) #1 2011-10-04 20:50 First, the new Explorer in ObjectDB is fantastic!

Indexing a field results in internal Exception

I have an application that I have been converting from JPA/MySQL to JDO/ObjectDB and I have hit a problem with indexing. An index on a String field is required to give good performance but if I add the @Index annotation to the field I eventually end up with an ObjectDB internal exception.  This is reproducible, as is the program running to completion (slowly) if I remove the @Index annotation.  Is there anything I can look for that might result in this exception? #1 2013-04-21 20:40 I have an application that I have been converting from JPA/MySQL to JDO/ObjectDB and I have hit a problem with in ...

To open source, or not to open source

Hi, We are currently using db4o with a commercial licence, but finds it very frustrating after they have been taken over by Versant. The development of db4o is going very slow and major bugfixes are not been backported to stable releases, but only put into bleeding edge branches.   Therefore we do the bugfix backporting ourself. This would not have be possible if db4o was close source.  #1 2012-02-01 09:59 Hi, We are currently using db4o with a commercial licence, but finds it very frustrating after they have ...
