Jython java call throws exception asking for 2 args when only one arg is coded

I have an Java method I want to call within my Jython servlet running on tomcat5. It looks like this:

@SuppressWarnings("unchecked")
    public School loadByName(String name) {
        List<School> school;
        school = getHibernateTemplate().find("from " + getPersistentClass().getName() + " where name = ?", name);

        return uniqueResult(school);
    }

I call it in Jython using:

foobar = SchoolDAOHibernate.loadByName('University')

It throws an error that says loadByName() expects 2 args; got 1. What other argument could it be looking for?

If i try to create an instance first such as:

foo = com.dc.sports.dao.hibernate.SchoolDaoHibernate()
foo.loadByName('University')

The first call throws an exception saying:

No visible constructors for class (com.dc.sports.dao.hibernate.SchoolDaoHibernate)

I'm assuming this is because it is a private-package:

package com.dc.sports.dao.hibernate;

...

@SuppressWarnings("unchecked")
class SchoolDaoHibernate extends Ab开发者_如何学PythonstractDaoHibernate<School> implements SchoolDao {

So how can I get at the method?

loadByName is not static. You need a instance to call it.

sdh = SchoolDAOHibernate(...) # ... any args for construction ??
sdh.loadByName('Univeristy') # 2 args :-) self (sdh) and 'University'

clearer ?

Because the loadByName method isn't static, Jython might be expecting the first argument to be an instance of SchoolDAOHibernate. If it makes sense for your design, make that method static.
