[jboss-user] [EJB 3.0] - Problems setting timer to entity bean
Hi, Im getting the below error while setting timer over an entity bean using 'timerService.createTimer(date, entitybean);'.

I added em.flush() just under em.persist() and it's solved the above problem. Hope this helps someone in the future.

[jboss-user] [JBossWS] - SimpleDeserializer error on returning complex type
Hi, I have exposed a stateless ejb3 bean as a WS and it has a method returning a complex type. Signature: @WebMethod | public MapBean getMap(String test) The class MapBean just has 2 string members along with their getters/setters. I'm using an axis WS client for it (using the Call interface) but invoking the Web service gives me the below error: Caused by: org.xml.sax.SAXException: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize. | at org.apache.axis.encoding.ser.SimpleDeserializer.onStartChild(SimpleDeserializer.java:145) | at org.apache.axis.encoding.DeserializationContext.startElement(DeserializationContext.java:1035) | at org.apache.axis.message.SAX2EventRecorder.replay(SAX2EventRecorder.java:165) | at org.apache.axis.message.MessageElement.publishToHandler(MessageElement.java:1141) | at org.apache.axis.message.RPCElement.deserialize(RPCElement.java:236) | at org.apache.axis.message.RPCElement.getParams(RPCElement.java:384) | at org.apache.axis.client.Call.invoke(Call.java:2448) | ... 3 more What's wierd is, it works without the error if I change the binding from document/wrapped to document/BARE but in that case the input arguements take the form 'arg0 xsi:type='xsd:string' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema'nabble/arg0' even inside the webmethod!

[jboss-user] [EJB 3.0] - Re: best way to expose ejb3 as web service?
Hi again,
Is it not possible to return a map/hashmap from the ejb web service? I'm using
an axis client for that as below Call call= (Call) service.createCall();
|call.setTargetEndpointAddress( new
java.net.URL(endpoint) );
|call.setOperationName(new
QName(http://session.um.com/;, getAuc) );
|
|
|call.addParameter(arg0,
| org.apache.axis.Constants.XSD_INT,
| javax.xml.rpc.ParameterMode.IN);
|
|
|call.setReturnClass(HashMap.class);
|HashMap ret = (HashMap) call.invoke( new Object[] {1}
Thought it throws no error, the returned Map never has any contents in them.
Also, if instead of setReturnClass I try to use
setReturnType(org.apache.axis.Constants.XSD_ANY) it gives me the below error:
could not find deserializer for type {http://www.w3.org/2001/XMLSchema}any

I posted the wrong code in the 2nd code section in the above post. Below is the
correct one:
@WebMethod
| public String checkLogin(String id, String pass)
| {
| User u = new UserManagerBean().check(id,pass);
|
| if(u==null)
| {
| return Invalid Username / Password;
| }
| else
| {
| return Success;
| }
| return u;
| }

[jboss-user] [EJB 3.0] - Re: best way to expose ejb3 as web service?
Thanks, that worked! But I have got another problem now. To avoid changing the existing stateless beans, for each, I have created a wrapper sort of stateless bean having the web service annotations and calling the methods in the existing beans. (This had to be done since the client app can't recognize many of the objects taken as parameters by methods of the existing beans.) But calling a method from the wrapper bean having a createQuery statement throws a NullPointerException. Any idea on why this might be?

[jboss-user] [EJB 3.0] - best way to expose ejb3 as web service?
I have an ejb3 component with a number of stateless and entity beans. What's the best and easiest way to expose the stateless beans as web services? Which method will require the least changes to be made to the beans themselves?
