Web service security with mutiple certificates

Question

Is it possible to secure a web service on OC4J such that multiple clients can securely access the same web service. I have been trying to send messages to the same web service end point using multiple signature keys. The problem that I am getting is that if I do not use the signature key specified within OC4J to sign the message I am receiving the following error "javax.xml.rpc.soap.SOAPFaultException: Chain does not terminate with a trusted CA". Note all the certificates are present in the configure OC4J keystore.
Can anyone point me in the direction of some documentation on how to configure a web service to be securely accessed by multiple clients (certificates)
Cheers

Here is an example where we have two keystores, Bob and Alice.
Bob's Keystore:
Entry Alias: alice (Trusted Certificate) >>> No password
Entry Alias: bob (Key Pair + CA Certs) >>> password welcome1
Alice's Keystore:
Entry Alias: bob (Trusted Certificate) >>> No password
Entry Alias: Alice (Key Pair + CA Certs) >>> password welcome1
In our scheme each party on the end of the message exchange have two key-pairs one for signature and one of encryption:
In the Oracle Web Service.xml you should see something to the effect:
<key-store name="mykeystore" store-pass="welcome1"
path="META-INF/bob.jks"/>
<signature-key key-pass="welcome1" alias="bob"/>
<encryption-key key-pass="welcome1" alias="bob"/>
Later in this XML, you would see the encrypt element, here we let it know to use alice for XML Encryption:
<encrypt>
<recipient-key alias="alice"/>
<encryption-method>AES-128</encryption-method>
<tbe-elements>
<tbe-element local-part="Body"
name-space="http://schemas.xmlsoap.org/soap/envelope/"/>
</tbe-elements>
</encrypt>
The default behavior is to only work with one client. If you need to work with multiple, then we have a means here:
