an array?
cheers

Hi all,
on the *client* side, the following exception is thrown:
Exception in thread "main" _java.lang.NullPointerException_
at herbieclient.test.holeBenutzer(_test.java:73_)
at herbieclient.test.main(_test.java:28_)
Line 73: System.out.println(buddies1.getName());
On the server side no exception is thrown.
Now, in order to understand the problem I have added the following
code in the server class right after the server code described in my
first mail:
//Setting the OMElement in the UserDesktopBean
bean.setBuddies(omElementBUD);
*new:*
HerbieObjectDesktopBean[] budtest = (HerbieObjectDesktopBean[])
BeanUtil.deserialize(omElementBUD, new
Object[]{HerbieObjectDesktopBean.class},new
AxisService().getObjectSupplier());
System.out.println(budtest.length);
Now, the following exception is thrown on the *server* side:
java.lang.ClassCastException:

*Subject:* [Axis2] Converting an OMElement into an Array of Objects
Hi All,
I am quite new to Axis2 and I am trying to develop a webservice for an
existing webapplication.
So far I managed to set up a basic webservice that transfers JavaBeans
(e.g. “UserDesktopBean”) and it possible to access all of the simple
data types from the client application. Unfortunately, even after
reading multiple AXIOM tutorials, I don’t know how to correctly work
with the JavaBeans nested inside the “UserDesktopBeans” that need to
be transferred as via AXIOM OMElement-wrapping.
At this time I use the following code to return an array of Objects as
an OMElement:
SERVER:
###########
//Converting an ArrayList to Array
Object[] budlist = buddies.toArray();
QName budQName = new
QName("http://desktop.core.herbie.buddies","buddies";);
OMElement omElementBUD = BeanUtil.getOMElement(budQName, budlist,
null, false, null);
//Setting the OMElement in the UserDesktopBean
bean.setBuddies(omElementBUD);
CLIENT:
############
//here I am trying to transform the array back
OMElement _buddies = benutzer.getBuddies();
ObjectSupplier os = new AxisService().getObjectSupplier();
Object[] budlist=new Object[]{HerbieWSStub.HerbieObjectDesktopBean.class};
Object[] buddies = BeanUtil.deserialize(_buddies,budlist,os);
//here I am trying to access the first array element
HerbieWSStub.HerbieObjectDesktopBean buddies1 =
(HerbieWSStub.HerbieObjectDesktopBean) buddies[0];
System.out.println(buddies1.getName());
Trying to access the array leads to an Exception at this time.
I would really appreciate, if you could help me with this problem.
For a better understanding of the underlying webservice, I’ve attached
the UserDesktopBean, the WSDL-File and the services.xml
Best Regards,
Sven
