Hi,
I don’t need any of this if you set the certificate in the Web Service Endpoint alias and call the WSD connector using that alias (or have the WSD binder ‘Port alias’ set).
On the other hand, if the other party’s CA isn’t present in the default truststore of the JVM, the call will be rejected on your side.
You might be mislead by the name “DEFAULT_IS_TRUSTSTORE”; just because it says so, it doesn’t mean it is.
Try setting the Global truststore to one with the needed CAs (Security->Certificates->Trustore).
Best regards,
