[ome-devel] using blitz

Dear Josh!

It's getting (slightly) better now :-)

Well, I am going to update soon, but currently the build from source
seems to be ok. The tests comming with ice-cpp passed all.

> Do you mind telling us how you installed Ice 3.3?

Ice-cpp:
I've installed mcpp from the third party tools archive zeroc provides.
Then I've simple type make in Ice-3.3.0/cpp and make test and sudo
make install. My IceHome path is /opt/Ice-3.3.0

Ice-py:
I've went to Ice-3.3.0/py and type make and make install.

Ice-java (which I didn't know that I don't need it):
I've installed berkeley-db java bindings using apt
I've went to Ice-3/java and typed ant ice-jar and copied Ice.jar to
/usr/share/java/

That's what I get. I don't have other slice2* from ubuntu packages on
the system, I've removed the zeroc-ice 3.2.1 packages prior installing
3.3.0 from source.

I'm working from Beta3.1. Yes, and Parameters are in omero.sys. How do
I know where to look for the classes? What are the name space
conventions? Is there a standard way to deduce the python class from
java code, if I find ome.parameters.Parameters in the javadocs as a
second parameter to IQuery?

I was now able to do something like this:
2 : import omero
3 : cl = omero.client()
4 : ses = cl.createSession('omero','omero')
5 : q = ses.getQueryService()
6 : omero.sys.Parameters(map={'name': omero.RString('omero')})
7 : omero.sys.Parameters(map={'name': omero.RString('omero')})
8 : param = omero.sys.Parameters(map={'name': omero.RString('omero')})
9 : q.findByQuery('select p from Project p where p.details.owner.name
= :name', param)

What I now get is a java exception:

serverExceptionClass = ome.conditions.ApiUsageException
    message = could not resolve property: name of:
ome.model.meta.Experimenter [select p from
ome.model.containers.Project p where p.details.owner.name = :name];
nested exception is org.hibernate.QueryException: could not resolve
property: name of: ome.model.meta.Experimenter [select p from
ome.model.containers.Project p where p.details.owner.name = :name]

I don't have JBOSS running, but as far as I understood, this is not
necessary anymore for omero-blitz to work, right?

I'm pretty sure this is not the case, I get the same version output as
you write above.
Did you check the ant output I've send. For me it seems some classes
cannot be found, I see some ClassNotFoundExcpt. for hibernate classes.

Well, currently there's no need to compile Beta3.1.1 myself it was
just that I though that the binary dist was not complete.

Thanks again! Bernhard
