Hi all,
I use Jonas 2.2.7 on win2000 and I implemented several
entity bean with bean managed persistence.
I call a Collection findSomething() method from a
servlet runing in Tomcat 3.2, then iterate the
Collection and call
get... methods on the ejbobjects:
...
result =
home.findByEverything(cod,denumire,unitate_ref,sortcolumn,sortord);
...
for(Iterator i=result.iterator();i.hasNext();)
{
v=(Valute)i.next();
cods.addElement(((ValutePK)v.getPrimaryKey()).cod);
//
names.addElement(v.getDenumire());
units.addElement(new Double(v.getUnitateRef()));
//
}
When I call the servlet for exactly 44 times, I get
a: twrown by one of the get... method
