Hi,
I was trying to test simple SOAP Service example.(a bit updated src)
The client creates a large number of threads and each thread builds its own call
object and sends two numbers to the server to add.
The results which I got were the following
o Exception occurred in the readConfigFile() method in the ServiceManager.java
Error processing configuration file
Error processing configuration file
Error was: org.xml.sax.SAXException: FWK005 parse may not be called while parsing.
Error was: org.xml.sax.SAXException: FWK005 parse may not be called while parsing.
o Exception occurred in the BaseConfigManager.java
java.lang.NullPointerException

I think that the BaseConfigManager Object is sharing by threads.
But, BaseConfigManager's instance variable(protected Hashtable dds = new
Hashtable()) is not thread-safe.
I wonder that is apache-soap lib thread-safe?
