Doc-style Web Services
Can a doc-style Web Service invoke an RPC-Style Web Service? I know that we cannot
mix RPC with Doc-style in the same Service, but I was wondering if RPC and Doc-style
can call each other.
Thanks,
John
Hi John,
Yes this is certainly possible. The role of client, server and service
gets blurred when dealing with multiple web services. For an example,
you can take a look at the work done by WS-I for the sample application
[1], where multiple types of web services communicate with each other.

Returning data with a doc style web service
How does one return information using a "Document" style Web Service? WLS 8.1 restricts
you to a single "in" parameter. Do I return information by using the "return"
value from the Web Service (assuming it's synchronous)? If so, what are the restrictions
on the return value. I've read the WLS 8.1 Programming Web Services document but
it's pretty lite in the area of Document style Web Services.
Thanks.WLS 8.1 supports two document styles:
#1 document literal
#2 document wrapped literal
In the case of #1 a web service method can only
take zero or one argument. There can be a return
type (or void). The (single) argument or return type
could be any supported type, or user defined complex
types (java beans). In #1 the dispatch is done based
on the incoming document and not based on the name
of the method. You can find an example for this at:
http://manojc.com/?sample13
In the case of #2 a web service method can have
any number of arguments. The WS container will
wrap the method in to a complexType. Here,
method name will be the name of the complexType
and arguments will be added as elements of the
complexType. In this case dispatch is done
based on the method name. An example here:
http://manojc.com/?sample14

Trouble Communicating with Document-Style Web Service
I have a flash app that currently communicates with a
RPC-style web service. I changed the web service to be
document-style, and the flash app no longer sends valid requests. I
was under the impression that one could simple swtich styles, and
flash would play along. Apparently, this is not the case. Does
anyone have an insight in this area?Clarified with Partick Calahan, who is maintaining this tool.
Currently, doc style is not handled by this tool. I guess it will be
supported in the future.
Thanks.

Retrieving client ip from RPC-style web service
Hi,
I've got an rpc-style web service and I would like to log the incoming client
ip address (i.e. I need to get at the HTTPRequest object). Can this be done by
passing some kind of SOAP context parameter in the argument list of my exposed
methods? If this is not doable, is implementing SOAP message handlers the way
to to go? I would rather not do the latter, as the web service is working well
and don't want to play with my code too much.
ThanksI tried this, following the example in http://e-docs.bea.com/wls/docs70/webapp/filters.html,
but I still can't get it to work. The init() method gets called, but doFilter(ServletRequest
req, ServletResponse resp, FilterChain fc) does not. The "filter" part of my
web.xml looks like:
<filter>
<filter-name>serviceFilter</filter-name>
<filter-class>webservices.ServiceFilterImpl</filter-class>
</filter>
<filter-mapping>
<filter-name>serviceFilter</filter-name>
<url-pattern>/myPattern/myWebService</url-pattern>
</filter-mapping>
The only thing I could thing of is that maybe my url-pattern is wrong, although
this seems unlikely as my web service is able to process requests sent using
http://myWLSMachine:7001/myPattern/myWebService.
In fact, in the the WLS access.log file, I have:
[07/Oct/2002:11:51:01 -0400] "POST /myPattern/myWebService HTTP/1.0" 200 3011.
Do you know if there's something in the JAX-RPC API that I could use to get at
the client ip address? I dug through the documentation and came across something
called "ServletEndpointContext", but I'm not sure if this will do the trick.
Thanks for your time,
Danielle

Hi Lenna,
You might take a look at the SOAPBuilders interop tests.
See: http://www.whitemesa.com/r3/interop3.html and notice the DocLit
tests.
Our endpoints are http://webservice.bea.com:7001 and the code for the
client and servers can be located here:
http://webservice.bea.com/index.html#qz40
The good folks with WS-I have spent many cycles on interop issues. You
might have a look at their work:

SwA with a doc/lit web service? 8.1sp3
For WL 8.1sp3, is it possible to do SwA using a doc/lit style web service? I'm not even sure if this makes sense, and it's not mentioned on any sites I've seen.
I'm trying to experiment how you can send binary data over XML with BEA WL 8.1sp3. It only supports SwA, which I believe can be used to send binary data at its raw size. However, I wanted to have a document-style web service.
The only examples for SwA use rpc style.If you want to send binary data (i.e. an image, a PDF file, a Word document, etc.) as opposed to an XML document, then you in essence want an RPC-style web service that has an operation that takes an javax.activation.DataHandler. You can build this web service using either the <servicegen> Ant task, or the WLW IDE (a .JWS).
Here's a link to the e-docs:
http://e-docs.bea.com/workshop/docs81/doc/en/workshop/guide/getstarted/conUsingSOAPAttachments.html
The one thing wrong (or missing) with that information, is that it doesn't tell you that you have to set the soap-style needs to be set to rpc. The default is document, which won't produce the the correct client proxy jar. Actually, you won't be able to produce the client proxy jar unless you set soap-style to rpc :-)

Need help with DOC type web service
hi,
I am trying to write a simple message style ( doc type ) web service but no success so far. I have tried to search for examples but no use. I already implemented some simple RPC style web services like calculator etc and able to use them. I am more interested in the DOC type ( which sends SOAP message and receives SOAP message back). Can Anybody give me an example for implementing this type of service ( very-simple say HellowWorld ) or point me to some website . I am not able to generate the response envelope. I can write the client program which will send a SOAP Envelope to this services with one parameter NAME and the services should return Hello Name but in a SOAP envelope form. I can create a SOAP message in this Client using SOAPConnection and MessageFactory etc. Your help will be really appreciated. There is very little stuff about webservices on the internet as well on this forum.
Thanks
VinodHello kwilding2,
Thanks for the quick response and pointing to some useful websites. I downloaded the code from web service essentials BUT all the examples are using SOAP RPC calls. They create a call object and call one of the service methods and a response is returned. I am little confused about this stuff. I am looking for something which returns the response in a SOAP envelope for which i think i need to use JAXM API which I already have downloaded. I have created a client which composes a SOAP envelope using SOAPConnection and other MessageFactory classes etc and can send this SOAP envelope to a web service. In return I want the web service to give the SOAP envelope.
I have gone thru xmethods.net and picked the following stock quote request and response:
Sample Request envelope:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance" xmlns:xsd="http://www.w3.org/1999/XMLSchema">
<SOAP-ENV:Body>
<ns1:getQuote xmlns:ns1="urn:xmethods-delayed-quotes" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<symbol xsi:type="xsd:string">IBM</symbol>
</ns1:getQuote>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Sample Response Envelope:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance" xmlns:xsd="http://www.w3.org/1999/XMLSchema">
<SOAP-ENV:Body>
<ns1:getQuoteResponse xmlns:ns1="urn:xmethods-delayed-quotes" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<return xsi:type="xsd:float">133.625</return>
</ns1:getQuoteResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
I also want the things in this order. This webservice at xmethods just returns the price for a stock, so how they say it returns this Response Envelope. Is this Envelope something implied. I am getting more confused.
any help will be appreciated.
Thanks

'Payload not Serializable' with custom WSDL data types in message-style web service
I'm implementing a message-style web service which publishes to a JMS Queue.
I had the web service built and deployed, but noticed that the "sendRequest" message's
part was of type "xsd:anyType." This is not specific enough for our interface,
since it is externally facing and needs to describe the object we're expecting
on the back end.
So I replaced xsd:anyType with mynamespace:MyType, which is defined as a complex
type in the same WSDL document.
My problem is that when I test the web service with the new WSDL (using the client.jar),
I get a server-side exception from the DestinationSendAdapter.doPost() method.
The exception reads:
javax.servlet.ServletException: Payload not Serializable
at weblogic.soap.server.servlet.DestinationSendAdapter.doPost(DestinationSendAdapter.java:129)
The domain object ('classic' JavaBean) that it should map to on the server side
extends a class that implements Serializable, so it should inherit the trait.
So my questions are:
1) Did I properly go about trying to restrict the object type that gets sent to
my Destination?
2) If no, what is the correct way? If yes, why am I receiving the Payload not
Serializable error if the domain object implements Serializable?
Thanks in advance.Resolved:
Apparently this is the right approach, as it boiled down to a classpath issue
on the client-side. Thanks anyway. -

Hi,
Has anyone tried (and maybe succeeded) in accessing an
RPC-style Web Service deployed on WebLogic Server 6.1 using
SSL? I have a Web Service deployed and am able to access it using JNDI and the
weblogic.soap.http.SoapInitialContextFactory
INITIAL_CONTEXT_FACTORY. However, when I try to set the
Context.SECURITY_PROTOCOL to "ssl" and access the secure port,
I get a "java.net.SocketException: Unexpected end of file from
the server" error message.
Does the weblogic.soap.http.SoapInitialContextFactory not
support SSL? Do I need to do the SOAP/XML messaging myself,
without being able to make use of the WebLogic convenience
classes? Thanks! RobAlright!
Glad you got it working ;-)
Actually, the problem with the protocol being hardcoded to http in the wsdl.jsp,
is a bit strange. It's unusual that the BEA engineers that coded the wsgen component
and support classes, didn't use something like the following:
<soap:address location="<%= request.getScheme() + "://" + request.getServerName()
+ ":" + request.getServerPort() %>/security/examples/webservices/security/PhoneBookService"/>
I don't use wsgen too much, because I need to have more control over the J2EE
packaging. It (wsgen) is great for spitting out stuff, but not really setup for
doing Web service packaging that use classes (i.e. helper files, frameworks, etc.)
that it doesn't generate. I think they (BEA) might be looking into integrating
the Web Services assembly process with other tools like WebGain, Forte, etc. to
alleviate these types of issues.
Anyway, glad you got it working, so now you can help somebody else (time permitting,
of course) with this topic in the future!

Mike,
Thank you very much for your response! The next to
last sentence did it for me (when you mentioned checking
that the location attribute of the soap:address element
was set properly)! I noticed that when I viewed the WSDL
file via the browser (by clicking on the link in the
index.html page), I saw http://host:<unsecure_port> when
I requested it over the unsecure port, but I saw
http://host:<secure_port> when I requested the WSDL over
the secure port. Notice it did not say https!
So, I unjarred the EAR file that was generated by my
wsgen task, and then unjarred the generated WAR file
contained therein. When I looked at wsdl.jsp, I noticed
that "http" was hard-coded in the location attribute, but
that the host name and port number were dynamically
generated. So I added a scriplet to dynamically place an
"s" after "http" (if request.isSecure()) and rejarred up
the WAR and EAR files.
Now when I deployed the EAR file, I see "https" when
I request the WSDL over the secure port, and my client
(actually your client;) works! Awesome! I really appreciate
your help! Now my only issue is why did the wsdl.jsp have
"http" hard-coded, not accounting for secure requests.
These files were generated by the WSGEN task in ANT.
I figure it's either: I have a configuration problem,
I have a problem with my ANT build script, my version of
WebLogic Server (6.1 w/SP1 built 9/18/2001) has a bug, or
maybe you just have to manually go in and modify the wsdl.jsp
file if you want to use https :(. Please let me know if
you have any insight on this, and I will also follow up
with WebLogic support. Thanks again! Rob

Hi Rob,
I am absolutely sure the code I posted works, so we need to approach
this from
a different angle ;-)
First, I know why the Context.SECURITY_PROTOCOL approach doesn't works.
It's because
the namespace in the Web Services code examples is not the same oneas
the one
used for RMI objects, EJBs, JDBC Data Sources, etc. For those objects,
the Context.PROVIDER_URL
is something like "t3://localhost:7001", and the INITIAL_CONTEXT_FACTORY
is "weblogic.jndi.WLInitialContextFactory".
The one being used with WebLogic Web Services, is mainly just functioning
as a
mechanism for manufacturing WebServiceProxy objects, because it is a
non-instanciable!
It does this by using a subclass of javax.naming.Context called SOAPContext,
which
is completely hidden from you, but also doesn't do much except implement
the lookup()
method. The implementation of this method ignores the Context.SECURITY_URL
property,
but it does pay attention to the "java.naming.security.principal" and
"java.naming.security.credentials"
properties. You don't need these properties for SSL, just Basic Authentication.
Enough about that, though. The service end-point is a servlet right?
So this means
it has a URL that begins with http or https, which in turn means the
WebLogic
servlet engine gets the SOAP request and sends it to the StatelessSessionAdapter
servlet. To WLS, this is just like any other HTTP/HTTPS request sent
to it ;-)
There is no special "SOAP-related" HTTP/HTTPS handler in WLS, but the
SSL challenge
dance still happens. So my first question is, are you sure you havethe
HTTPS
attributes set properly in the WebLogic console. SSL/HTTPS should be
enabled and
the "Hostname Verification Ignored" checkbox should be checked. Next,
are you
sure the URL assigned to the location attribute of the <service> element
in the
WSDL is correct (i.e. https://localhost:7002)? Are you using the "dynamic
client"
approach?

Mike,
Thanks for your response. I downloaded the code example that
you
posted
last week, as well as the code example that you posted in October for
a similar
request (BEA Support pointed me towards that). Unfortunately, I still
can't get
the Web Service to respond to the client request when the client uses
the HTTPS
port for the WebLogic Server.
I tried two different client approaches. The first uses the client
code
that you posted in October, the WebServiceProxy approach. The second
approach
is based on the example in the WebLogic documentation, which uses the
weblogic.soap.SoapInitialContextFactory
class with the javax.naming.Context object to perform a lookup on the
service
(which closely resembles rmi without the narrowing).
Both client classes fail to invoke the the service itself viaHTTPS
(although
they both work when making HTTP requests to the unsecure port). However,
when
I run the client based on the client class that you posted in October
and make
an HTTPS request, I can see in the output where it is able to download
the WSDL
file and use it (via the WebServiceProxy) to describe the availablemethods
for
the associated Web Service. It is only when the actual invoke() method
is called
on the SoapMethod object (which in turn sends the XML request to the
Web Service
Servlet), that the server doesn't respond, and the client fails with
an UnexpectedEndOfFileException
(i.e. no response).
So, do you know why the servlet that the RPC-style Web Serviceuses
to handle
requests would not respond to HTTPS requests, when it processes HTTP
requests
without a problem (using the same client code that fails with the HTTPS
request)?
I am using WebLogic Server 6.1 w/SP1 on a Solaris 8 platform. Thanks
for any
advice you can give me! Rob

Hi Rob,
Check out the attached zip for "insights" into how to do this. It
contains
the
code for two Web service "consumers" (that the new fangled word fora
"client")
and the web.xml and weblogic.xml for the RPC-style Web Service, that
they consume.
Hope this helps,

Calling a document style web service using a pl/sql wrapper method
Just wanted to find out if anybody has a working example of invoking a document style web service from Oracle 10g database on a Unix environment.
We have java test class that invokes the web service, and we are trying to use a pl/sql wrapper to invoke a Java Web Service client. So far, we are encountering an End of File Communication error from Oracle which essentially terminates the session with the database.
On the Oracle application server side we are able to see a successful HTTP request made to the application server via server log, which is hosting the web service, since we are registering HTTP 200 success codes. However, we do not see any other errors from the application in the server logs. Most likely since the client side fails, before actually getting a chance to invoke the web service. This has been verified by commenting the client code leaving the print statements. The first call to the Service Factory method (XFire) to look up the service is where the PL/SQL procedure fails with an End of File communication error.Remove the when others section and see the actual error and post that.

Has anyone seen this before? Am I missing something?
Thanks,
TimHi Tim,
I think the problem is that you are assuming that the data type, of the message
argument to the onMessage(Message message) method in your MDB, is of type TextMessage.
I agree that this seems logical, especially since you passed "a string" to the
Message-style Web Service. However, this is not the case, because the WSDL uses
the "xsd:anyType" as the data type for any argument you pass to the send() method
;-) This maps to a java.lang.Object in the WebLogic Web Services implementation,
which is why you get the casting error. Try this instead:
public void onMessage(Message msg)
try
String msgText;
ObjectMessage objMessage = (ObjectMessage)msg;
msgText = (String)objMessage.getObject();
System.out.println("[PostDefaultPayment.onMessage(Message)] msgText=" + msgText);
System.out.println("[PostDefaultPayment.onMessage(Message)] msg.getJMSType()="
+ msg.getJMSType());
System.out.println("[PostDefaultPayment.onMessage(Message)] msg.getJMSCorrelationID()="
+ msg.getJMSCorrelationID());
System.out.println("[PostDefaultPayment.onMessage(Message)] msg.getJMSMessageID()="
+ msg.getJMSMessageID());

e.printStackTrace();

Hi there.
I'm student and have a little project in university.
So now i'm facing one problem: can't find any tutorial on rest style web services.
As looking or articles in google there are some papers, but they are about some frameworks.
As for me i don't need any of framework. So if you know any good site or have any examples on rest style web service programing let me know...
Thanks in advance.
SauliusThe default for HTTPService is resultFormat="object" This
causes Flex to convert your xml into a tree of dynamic objects.
This is rarely what you want. Among other things, it tries to do
type conversions.
Instead, set resultFormat="e4x". This will give you your xml
un changed. It also gives you access to the e4x API which is very
powerful. It includes traversal, search and fileter functionality.
Additionally, for anything but a trivial or demo app, do not
bind directly to lastResult. Instead, use a result handler
function. Here is an example, untested:
<mx:HTTPService id="myService"... result="onResult(event)"
(in script)
import mx.rpc.ResultEvent;
[Bindable]private var _xmlResult:XML; //instance var to hold
the data
private function onResult(event:ResultEvent):void {
_xmlResult = XML(event.result);
trace(_xmlResult.toXMLString()); //to see exactly what you
have
Note, your xml example is not valid, so I can't show an
example of an e4x expression.

Document style Web Service the standard?
Hi,
A colleague of mine just told me that we should not be building RPC style web services since document style are the standard now. Is this true? I couldn't find any such phrase in WS-I BP 1.0.
If this is not true then is it even a possiblity that in future Document style will be the standard?
Thanks, Sid.In this context I think your friend is using 'standard' to mean 'reasonably common and quite trendy at the moment'.
RPC based WS was a bad idea in because it destroys some of the loose coupling you gain using WS rather than say, CORBA, which is the number three reason for using WS. (number one being your boss spent lots of money on the tools and would look silly if you don't use them, and number two being WS tunnelling through firewalls).
