Lev,
My bad. Actually it is the Stripes filter w/ appropriate arguments in
the web.xml that indirectly initializes the Stripersist module.
Your exception is occurring b/c Stripersist has not been initialized
(yes - I know - this is the understatement of the week ;-)
Unfortunately I didn't notice that my tests had code that created a
MockServletContext that setup Stripes and included in the
Extension.Packages the argument "org.stripesstuff.stripersist" that
initializes Stripersist.
I had code strewn across a heirarchy of classes to provide different
types of test frameworks... hopefully this snippet helps:
Map<String, String> filterParams = new HashMap<String, String>();
filterParams.put("Extension.Packages",
"org.stripesstuff.stripersist");
MockServletContext servletContext = new
MockServletContext("WebTest");
servletContext.addFilter(StripesFilter.class, "StripesFilter",
filterParams);
servletContext.setServlet(DispatcherServlet.class,
"StripesDispatcher", null);
Stripersist.requestInit();
BTW after the save you will explicitly need to call:
userDao.commit(userObject);
As Stripersist automatically begins a transaction for you but doesn't
automatically commit it for you (for obvious reasons... e.g. rollback).
