Could not locate metadata (orm.xml)
Hi,
Can anyone point me to a working standalone example there a a orm.xml file
is used instead of Annotations?
I'm able to build a small example with annotations but if I try the same
with orm.xml I receive the following error:
Exception in thread "main" <openjpa-1.0.2-r420667:627158 fatal user error>
org.apache.openjpa.persistence.ArgumentException: Could not locate metadata
for the class using alias "MYAPPLICATION.PEOPLETABLE". This could mean that
the OpenJPA enhancer or load-time weaver was not run on the type whose alias
is "MYAPPLICATION.PEOPLETABLE". Registered alias mappings: "{
MYAPPLICATION.PEOPLETABLE=null, Person=[class datamodel.Person]}"
I have the following orm.xml
<entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/ormorm_1_0.xsd"
version="1.0">
<entity class="datamodel.Person">
<table name="MYAPPLICATION.PEOPLETABLE"/>
<attributes>
<id name="id" />
<basic name="firstName" />
<basic name="lastName" />
<transient name="nonsenseField" />
</attributes>
</entity>
</entity-mappings>
I have the following persistence.xml
<?xml version="1.0" encoding="UTF-8"?>

Hi Fay,
yes both are in the same directory. I tried with and without mapping entry
in persistence. For reference I attached the content of my source directory.
It is a very tiny example
If someone wants to test this, please run Main.java.
Best regards, Lars

Re: Could not locate metadata (orm.xml)
Posted by Lars Vogel <la...@googlemail.com>.
Hi Adam,
thank you. If I remove the <mapping-file> I still get the same error. I
change the header to your header but still no difference. I paste the new
version of my files below.
Both orm.xml and persistence.xml are in the same directory META-INF.
Any further advice?

Re: Could not locate metadata (orm.xml)
Posted by Adam Hardy <ad...@cyberspaceroad.org>.
Hi Lars,
that is a weird error that I haven't seen before - it looks like OpenJPA is
confusing the table name with the class name.
In case it helps, you don't need to reference the orm.xml in the
persistence.xml. Not sure if it's a problem when you do, try without.
orm.xml looks like it's in the same directory as persistence.xml from your
email. perhaps you should double-check.
my orm.xml header is slightly different:
<?xml version="1.0" encoding="UTF-8"?>
<entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm
http://java.sun.com/xml/ns/persistence/orm_1_0.xsd"
version="1.0">
I do not run the OpenJPA enhancer and you shouldn't need to, but I am using the
OpenJPA v1.1.0 snapshot, not 1.0.x.

Hello,
thank you all for your very quick and constructive feedback. I'll clean my
example up and post it later to this group so that others can use it also as
a starting point (if desired).
Thank you again, Lars
Re: Could not locate metadata (orm.xml)
Posted by Lars Vogel <la...@googlemail.com>.
Hello,
cool script. I modified it a little bit so that it runs for me....
Thanks to your script I'm now able to create a working example. I believe I
confused @Table(name="MYAPPLICATION.PEOPLETABLE") with @Entity(name="
MYAPPLICATION.PEOPLETABLE") in my annotation example and this let me to
incorrect orm.xml coding.
Thank you very much.

Re: Could not locate metadata (orm.xml)
Posted by os_developer <os...@yahoo.com>.
Lars,
In your ant build script, I don't see where you are
specifying against which database the reverse mapping
tool should run. You need to provide your username and
password as well.
In my setup, I have an initial database already up and
running. In my build directory, I have a build.xml
file and then a META-INF/persistence.xml file.
When I run "ant reversemap" of my build.xml file, it
generates an orm.xml file and all of my java source.
You will have to update my files with your database
info but here they are in case they might be of help.
I did have to modify the orm.xml file a bit after it
was created so it was exactly how I wanted, but it did
work as-is without my changes.
Here's my persistence.xml file (and below is my
build.xml file):

Re: Could not locate metadata (orm.xml)
Posted by Lars Vogel <la...@googlemail.com>.
Hi Andreas,
thank you for your response.
I tried this. If I run the Ant task example from the OpenJPA manual for
creating a schema (Schema Tool Ant Task) then the system tells me:
[schematool] The options supplied to the SchemaToolTask are not valid.
Please check your ant build file.
If I try to run the mapping tool against the database I receive the
following:
[reversemappingtool] <openjpa-1.0.2-r420667:627158 fatal user error>
org.apache.openjpa.util.UserException: A JDBC Driver or DataSource class
name must be specified in the ConnectionDriverName property.
Below is my ant task:
Any idea what is wrong?
Thank you, Lars

Re: Could not locate metadata (orm.xml)
Posted by os_developer <os...@yahoo.com>.
I'm not sure if your orm.xml file is invalid or not
but one of the ways I've found to get a start on a
valid orm.xml file when I wasn't sure if mine was
correct was to use the Reverse Mapping tool in openjpa
(see the manual for more info).
If you already have a working example using
annotations, you can use the ant task to create your
orm.xml file for you, based on what you already have
in the database from your previous working example.
I do know that my orm.xml files look very different
from yours but I don't know where exactly the problem
might be.
