Help me pls to resolve the problem: WebService client SOAP exception: SAXException: Could not instantiate bean ...

Question

Hi all,
I use Weblogic 6.1 SOAP
If any body know what does this mean and how this may be resolved please
help me
I try to send JavaBean class "A" which includes an array of JavaBean class
"B" which includes an array of string objects
from server side to the client.
class A {
B[] aBeans
setABeans(B[] aBeans) {}
getABeans() {}
class B {
String[] props;
setProps(String[] props) {}
getProps() {}
And only half of the method invocation is ok - data is transmitted by soap
and is displayed
at the client side in "verbose=true" mode and i see that data is received
completely but the client side JavaBean class "A"
was not initialized because the exception was thrown when soap trying to
instantiate JavaBean class "B":
SAXException: Could not instantiate bean: B
I looked at jdk API and the InstantiationException is thrown only if class
is an interface or an abstract class,
but class "B" is not abstract or interface, it is simple JavaBean class.
What is the trouble?
Help me pls

Hi!
I think I know the problem.
Does your JavaBean has a default constructor (a parameterlessconstructor).

Try it!
