    ORA-30625: method dispatch on NULL SELF argument is disallowed

    930817
      Im trying to send data through web service using xml.
      While doing so im getting an error

      ORA-30625: method dispatch on NULL SELF argument is disallowed

      This seems to be because of special html characters being sent as xml.
      Need help on how to invoke web service and send special characters like <,>,& etc using xml.

      Im using Oracle 9i.

          It's difficult to help without seeing what you're actually doing.

          That error occurs when you invoke an object method but the object is NULL.

          Since you're working with XML, maybe somewhere in your code, you're trying to use something like .extract('<xpath expr>') on a NULL XMLType instance.
          But that's only a wild guess so far.

          Show us some code to be sure.
