Re: newbie problems
Hi Dmitry,
I don't know what's going wrong when running the tutorial (seems that
Product.class was correctly enhanced by the JDO enhancer).
But I wouldn't recommend OJB's JDO 1.0-api implementation for production
environments.
The PB-api and ODMG-api are stable and ready for production use
http://db.apache.org/ojb/status.html
If you want to use JDO, please have a look at JPOX or Speedo (or other
projects)
http://www.jpox.org/index.jsp

regards,
Armin

Hi,
I am developing a java application and I am considering OJB technology to
store objects' states seamlessly in the PostgreSQL database.
In short I am failing to get tutorial5 up and running. I followed
instructions on this link:
http://db.apache.org/ojb/docu/tutorials/jdo-tutorial.html
My actions:
1) downloaded ojb-blank.jar
2) downloaded tutorial5-src.jar
3) downloaded db-ojb-1.0.4.jar
4) downloaded jdo.jar,jdori-enhancer.jar,jdori.jar (jdo 1.0.1 RI)
5) downloaded PostgreSQL drivers pg74.216.jdbc3.jar postgresql-8.1-405.jdbc3.jar
my top directory is ojb-blank
I put *jar files into lib (ojb-blank/lib)
I put tutorial5 sources to (ojb_blank/src/java/org/apache/ojb/tutorial5)
I modified buid.properties, so it looks like this:
jcdAlias=default
databaseName=ojb
databaseUser=postgres
databasePassword=
dbmsName=PostgreSQL
jdbcLevel=3.0
jdbcRuntimeDriver=org.postgresql.Driver
urlProtocol=jdbc
urlSubprotocol=postgresql
urlDbalias=//localhost/${databaseName}
torque.database=postgresql
torque.database.createUrl=${urlProtocol}:${urlSubprotocol}:${urlDbalias}
jar.name=my-project.jar
source.dir=src
source.java.dir=${source.dir}/java
source.resource.dir=${source.dir}/resources
source.test.dir=${source.dir}/test
source.schema.dir=${source.dir}/schema
build.dir=build
lib.dir=lib
target.dir=target
I do not recall changing build.xml.
1) DB setup
ant build setup-db
runs w/ errors, but it creates *.sql files which I run byu hand and next
time around
ant build setup-db
runs w/o errors. So I consider it is a success:
$ psql ojb
Welcome to psql 8.0.3, the PostgreSQL interactive terminal.

2) ant build

Re: newbie problems
Thank you Armin, Please educate me a bit, cause I am a bit perplexed by your mail. You say OJB does not work well w/ JDO, use ODMG or PB OK, I understand that. then you say: If you want to use JDO, please have a look at JPOX or Speedo (or other JPOX is a implementation of JDO, isn't it? So can I use OJB w/ JPOX then? Or should I just use JPOX ? (this indicates my confusion at what exactly OJB does on the top of JDO). Please help me out.

OJB is a O/R-mapper with different supported API's (PB-api, ODMG-api, prototype JDO1.0), JPOX only supports the JDO-api. HTH regards, Armin Please help me out.

Basically, the JDO support in OJB works only with Sun JDO 1.0.1 [1]. If you want to stay in Apache home, you should try Apache JDO wich is working on a final release of a JDO 2 version.

Brokers leak
Hi all, I experienced brokers leaks. I checked all the open / close broker methods and the leaks still remains. ODMG transaction have been checked too. Those leaks result in PersistentBroker I/O Exception, freezing application. I would be very happy to known which methods take my brokers without give them back. Is there a simple way to known from where they are lost? Can P6Spy help ? What are the main reasons to have a broker leak ? I suspect unfinished Query iterations : what is the clean way to end an iteration before the end of the query iteration ? persistentBroker.close() does ? I suspect checkpoint() : but if i well guess, it's only a tx.commit() and a re-tx.begin() , so ... I suspect brokers can't be closed in some case, even when the close() is in finally code. Is that possible ?! e.g. when returning a value ? I suspect jsp iteration. We tried to iterate only java collections in the jsp, but it still remains query iteration inside. May be those iterations can take brokers automatically, but can't close them? So, is there a setting of brokers pool to avoid this? Documentation is short. Is there a chance to have the 1.0.5 in current month ? Thanks for all your ideas. Using OJB 1.0.4, oracle 10g, QueriesByCriteria, ReportQueries and ODMG transactions.
