Cannot retrieve back just saved objects without committing transaction

Hi, all I have a problem when I try to insert an object in a data base table and then try to retrieve all records from that table. I use the same persistence broker for the above two operations. I found that if I don't commit the transaction after save, the retrieved records won't include the new

ODMG Lock Not Granted Exception

Hi, Have you try to use TIMESTAMP for your jdbc-type, you can try like this : field-descriptor id=18 name=d8cleh column=D8CLEH jdbc-type=TIMESTAMP conversion=org.apache.ojb.broker.accesslayer.conversions.JavaDate2SqlTimest ampFieldConversion / The class for the

RE: TimeStamp Error Codes

First of all did you understand what my mail is for? If I don't know what OJB is for I might not have even tried to test that one and not wasted your valuable time. There are four points in my mail and all are valid ones. If you don't know what I meant don't even try to answer. Thanks

Re: TimeStamp Error Codes

Keep cool. When working with a community, is normal to get some messages of all kind. AFAIK, I've not worked with IBM DB2, but all databases has a TIMESTAMP like data type, and some has no capabilities for millisecond (as example, some databases like MS SQL Server store with 1000/3 milliseconds

thread-safe

Hi, just a question about thread-safty. i use OJB to store business-objects in a webapp. in my struts-actions i use my own class called OJBDelegate. Its methods are not! delcared with synchronized. now my question: is ojb threadsafe? if two or more struts-actions call the same method of my

Starting applicatio via ant

Hi, I have a quite strange problem: I am trying to start an ojb-based application via ant and the commons-laucher tool. I have struggled some time with setting the classpath correctly and it works now fine - except for one ugly thing: I had to pass an ABSOLUTE path in the OJB.properties -file

Re: Proxy prefetching limit in Collection and Reference descriptors.

hi Jakob, Thanks for answer. But I think there is other logic. In ojb.properties I have SqlInLimit set to 200, but when prefetching of proxy collection is performed I found that field _limit in class PBCollectionProxyListener (inner of class QueryReferenceBroker) field m_ProxyPrefetchingLimit

Re: AW: AW: AW: Two 1:N mappings to one table

Ah hah! You are allowing DB2 to add the ID via a trigger, aren't you? OJB doesn't play super nicely with the database doing that for it behind the scenes, unfortunately. If you are allowed, try using one of the OJB auto increment modules. I suggest the one that pulls from a db sequence if that

AW: AW: AW: AW: Two 1:N mappings to one table

hm. our db2 database tables are configured with an autoincrement for the primary keys by default. (for exampl: activityId INTEGER NOT NULL GENERATED BY DEFAULT AS IDENTITY (STARTS WITH 1, INCREMENT BY 1, NO CACHE, PRIMARY KEY). this is my first time using ojb. Meanwhile I get aware of what ojb

Re: AW: AW: AW: AW: Two 1:N mappings to one table

No! You misunderstood me. Declare the PK's, FK's etc in the database. Do not abandon good database practices for OJB -- particularly as never know what programs will access the DB directly in the future. The DB managed auto-increment is the thing that is causing OJB to hiccup on you, I

Re: AW: AW: AW: AW: Two 1:N mappings to one table

Hi Dirk, if you use Identity columns from database you can't use the default SequenceManager (SequenceManagerHighLowImpl). Have a look in http://db.apache.org/ojb/sequencemanager.html#nativeSequenceManager can all do for me. In the repository-user.xml I set every pk column with
