Hi,
Oks I got it. Ant is already running my program. It was specified in
build.xml. But still from where it is finding Persistence.java. It is
not in my Java distribution. So, is it included in the jars of Openjpa
?
thanks

Hi Ashish,
The first thing I will check is your classpath.
Looks like you are trying to run "java hellojpa.Main " but this is
already
part of "ant" that you run and the output from ant command
"run:
[java] 4782 hellojpa TRACE [main] openjpa.jdbc.SQL - <t 16322634,
conn 2
7041558> executing prepstmnt 26426059 INSERT INTO Message (id, created,
message)
....
"
is part of running hellojpa.Main from with in ant.
Regards,
Ravi.

Hi,
Thanks guys, I got my build succesful with ant but now I am stuck with
another (silly) problem. After build succesful when I am trying to run
the program it is not able to find the Persistence class file. Is
there some specific way in which I got to run the file. The error that
I received is as follows:
E:\apache-openjpa-1.2.1\examples>cd hellojpa

Hi Ashish,
It looks like the Apache parent pom is corrupted. Could you try
removing
the
C:\Documents and Settings\ashish\.m2\reposi
tory\org\apache\apache\4\ directory and re-running your maven build?
Here's what I'm keying off of :
Caused by: org.apache.maven.project.
InvalidProjectModelException: Not a v4.0.0 POM. for project
org.apache:apache at C:\Documents and
Settings\ashish\.m2\repository\org\apache\apache\4\apache-4.pom
I've never used conf.xml though, have you tried running the build
without
it?
Just my two cents. Paul's suggestion of running the samples will also
help
to determine the root cause.

Can you get it to work without Maven and without Eclipse first? You
should
be able to (1) download OpenJPA 1.2.1, (2) cd to examples/hellojpa,
(3)
type
"ant"
That should be all you have to do. If that does not end in "BUILD
SUCCESSFUL" please send the output to this list.
Once you have that much working you can have "fun" with Maven and
Eclipse
;-)

Hi,
Do I need to make any changes in my conf.xml file for maven. I have
already specified the proxy settings there. I am stuck with this
problem for a while now and not able to figure what is the problem.
Can anyone please suggest what is the problem or any changes that I
need to make in either Pom.xml or conf.xml to build my project.
thanks

Hi,
I downloaded the source code from the site and was trying to build
it.
While giving the command mvn install, my build fails because it says
that "might not be this projects POM". Do I need to change the
POM.xml
file or run mvn install from somewhere else first.
My stack trace is attached here with.

Hello,
I am new GSOC guy and I will be working on the Slice module. I was
trying to set up my development environment and downloaded the
1.2.1
release for the same. I was trying to compile the hellojpa program
given in example folder but it is not able to find
javax.persistence
package. Actually there is no persistence package in my standard
java
distribution.
Can someone please tell me how to sort out this problem. Also is
there
some eclipse plugin to work with OpenJPA.
Being new to this type of work environment, I might be asking lot
of
stupid questions at first, so please bear with me.
thanks and regards
