What makes a Java Bean invaild for a model import?

Question

I'm busy prototyping some functionality that will expose some MDM 5.5 data through a WebDynpro application.  I'm having a problem creating a java bean that will sit in front of an EJB, in that the Bean importer will refuse to import a bean if a certain line of code in a method is visible.  Here's the offending code from the method:
try {
     A2iResultSet rs = cat.GetRecordsByValue(ary, rsd, Schema.MyTable.NAME);
     setEventLocation(rs.GetValueAt(0, Schema.MyTable.EVENT_LOCATION).GetStringValue());
} catch (StringException e) {
     setEventLocation("failed to find record");
Note that I have a class instance variable called 'eventLocation', which has get/set methods defined for it, thereby satisfying the Javabean requirement.
The first two lines of the 'try' block are the problem.  If I comment them out and assemble the DC, I can import the Bean into a model with no issues.  If I uncomment them, I cannot import the bean - I get a message that says 'Invalid Jar - no beans to import'.
Can someone explain why this is happening?  Does it have something to do with the StringException?  As far as I can tell from the Java bean model import documentation, I think I'm doing everything correctly, but something must be amiss.
Suggestions?

Pablo,
Now I understand your question in comments to my blog better
You have to add "ejb20" classes to your WebDynpro project as well, and import model afterwards.
In WebDynpro DC expand path (<project> -> DC MetData -> DC Definition -> Used DC) and invoke "Add Used DC..." in contextual menu. In dialog select "<dev. config> -> SAP-J2EE -> ejb20 -> DC MetaData -> Public Parts -> default". Set dependencies Built-time (probably Design-time as well). Click OK. Try to import model. If fails, restart IDE and try to import again.
