   Brought to you by the same folks that brought you UDDI, is the Web Services Definition
Language. WSDL is an XML schema that defines documents, in XML format, that describe SOAP
services. There is an IBM alphaWorks toolkit that generates Java service client libraries
and service handler skeletons from a WSDL document. See the WSDL specification (<A HREF="http://www-106.ibm.com/developerworks/library/w-wsdl.html">http://www-106.ibm.com/developerworks/library/w-wsdl.html</a>),

the Apache SOAP administration client?</A></STRONG><BR>
   There are a number of possible solutions (none of which are perfect):<BR>- Modify
your servlet container's security settings so that only certain IP addresses can access the
admin page. If you are running Tomcat with its security manager, you can add an entry for
the soap webapp in the .policy file located in the conf directory, and then you can control
which IP addresses the webapp will accept connections from.<BR>- Modify the code - see
<A HREF="http://soap.manilasites.com/stories/storyReader$13">http://soap.manilasites.com/stories/storyReader$13</a>
<BR>- Modify your firewall configuration. Some firewalls can filter on URLs, and you
could use this to prevent accesses to the admin page (although this wouldn't prevent someone
from running the ServiceManagerClient directly).<p>
  +2.38&nbsp;&nbsp;<STRONG><A NAME="Q2_38">How can I get the IP address
of a client that is using my SOAP Service?</A></STRONG><BR>
  +If you add a SOAPContext Object as first Parameter in the signature of your SOAP-service
java-method, a 'SOAPContext' Object is passed to your class, e.g.:    <BR>    .mymethod(SOAPContext
inContext, String inString)<BR><BR>This SOAPContext object gives you access to
the HttpSession, HttpRequest, HttpResponse (see java doc for details).<BR>So, your SOAP
service method can get the servlet request out of the context object, and then call the getRemoteAddr()
method on the service request object: <BR><BR>import javax.servlet.http.*; <BR>....
<BR>HttpServletRequest req = <BR>(HttpServletRequest)soapCtx.getProperty(org.apache.soap.Constants.BAG_HTTPSERVLETREQUEST);
<BR>String remoteIPAddress = req.getRemoteAddr();<BR><BR>NOTE: this will

See here: <A HREF="http://www.pocketsoap.com/wsdl/">http://www.pocketsoap.com/wsdl/</a>.
Note that the current version only checks the relationships between the various parts of the
WSDL, it doesn't really check anything in the schema sections yet. A couple of folks on the
schematron mailing list are working on some XSD checking code, and it will be added to the
validator when its done.<p>
