Axis works very well and I like it a lot. I am using Axis 1.1 final in WSAD 5 and it runs fine normally.
The only thing is that when I am running and make any change at all to my implementation class, then WSAD/Websphere reloads the servlet to pick up the change (so far so good), and right away I get exceptions (see below) that force me to manually restart the application. This occurs reproducibly every time.
I have attached the source but cannot figure out exactly what is happening. Maybe someone else can see. Somehow it is getting a class cast exception running deployTypeMapping, called from initTMR.
BeanSerializerFactory is getting the ClassCastException at the line marked <======= below.
Variables are as follows:
constructor has
clazz= java.lang.Class (org.apache.axis.encoding.ser.BeanSerializerFactory) (id=281)
modifiers= 1
parameterTypes= java.lang.Class[2] (id=290)
[0]= java.lang.Class (java.lang.Class) (id=282)
[1]= java.lang.Class (javax.xml.namespace.QName) (id=285)
factory is
factory= java.lang.Class (org.apache.axis.encoding.ser.BeanSerializerFactory) (id=281)
xmlType is
xmlType= javax.xml.namespace.QName (id=284)
localPart= "SearchControlParameters"
namespaceURI= "http://t.ncfbins.com/tranzax/";javaType is
javaType= java.lang.Class (com.ncfbins.hostaccess.generated.SearchControlParameters) (id=283)
Again, all of this works on normal load. It is only when the servlet is *re-loaded" that the problem occurs.
Any suggestions would be appreciated.
Thanks!
