Hi, I have a couple of web services running on JBOSS 4.0.3SP1. I access these services using stand-alone clients (Java client using AXIS and Perl client using SOAP Lite). Both clients work fine; can invoke methods and get values returned to them including String Arrays. I deployed the same application in JBOSS 4.0.4GA. Now both clients are having issues - albeit different issues. Here they are: 1. Java client can invoke methods that return Simple Types, but not String Arrays or Complex Types. Here is the error I see on the client: org.xml.sax.SAXException: Deserializing parameter 'result': could not find deserializer for type {http://vcc.ws.eds.com/types/arrays/java/lang}StringArray at org.apache.axis.AxisFault.makeFault(AxisFault.java:101) at org.apache.axis.client.Call.invoke(Call.java:2470) 2. Perl client cannot invoke any method. Here is the error I see on the client side (the same error appears in JBOSS log as well): Error: Endpoint {http://vcc.ws.eds.com/}VCCSecurityQueryPort does not contain operation meta data for: {http://148.92.114.81:7070/vcc_security_ws}doesUserExist Any ideas? I know the web services stack changed from 4.0.3 to 4.0.4 and JBOSS moved away from AXIS. Are these the known issues? Thanks.
