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.

newbie problems
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.
Type: \copyright for distribution terms
\h for help with SQL commands
\? for help with psql commands
\g or terminate with semicolon to execute query
\q to quit
ojb=# \d

public | ojb_dset_entries | table | postgres
public | ojb_hl_seq| table | postgres
public | ojb_nrm | table | postgres
public | product | table | postgres
(9 rows)
2) ant build
$ ant build
Buildfile: build.xml
compile:

so I am encouraged , I proceed to the next step:
3) ant enhance-jdori
$ ant enhance-jdori
