RPC style web service client

hi,
i am new to web service technology. i want to create dynamic web service client for a "rpc" style web service in Netbeans.
please, can anybody guide me for this?
thanks in advance.

Hi,
To avoid creating new topic I will put my question here.
I try to create new web service (rpc-style) client in netbeans. I have rpc plugin installed. In ejb module node I right click > new > web service client >
I fill all filds, chose rpc-style and > after clicking finish - error occur:java.lang.LinkageError: com/sun/xml/rpc/processor/generator/Names

I use netbeans 6.5. In my project I choose java ee 5 as in 1.4 there is no web service client option
Any ideas?
I found some rpc tutorils for netbeans 4.0 but I wonder why it couldn't be done in netbean 6.5

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.
Thanks

I 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

RPC Style Web Service and SSL

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! Rob

Alright!
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 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.

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.

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).

Can XI handle RPC based web services ?

Is it possible with XI 3.0 to work with RPC based webservices rather than Document based services.
If it can, can some one send me sample configuration for SOAP Receiver and SOAP Sender.
I have successfully configured an SOAP Receiver to access external web service on internet which is a document based but I am having difficulty in accessing rpc based webservice on intranet.
We are on XI 3.0 SP 14. Appreciate your comments on this topic.
Thanks

I have opened an OSS message regarding this topic and I was told that RPC-style Web Services are not supported within the XI SOAP adapter. Our current workaround which adds the missing Web Service operation using an additional XSLT mapping is not sufficient. Instead we have to change our WSDL from RPC-style into document-literal style.

DII client for accessing a document style web service

Hi All,
I try to access a document style web service using DII JAX-RPC client and used the wscompile tool to produce wrapper classes .
The following code I used for my work:

XML Parser Error while creating Web service Client using JAX RPC

hello evryone,
Im facing XML Parser Error while creating web service client using JAX RPC. Im using Net Beans IDE for development purpose. I have wrote configuration file for client. Now i want to create Client stub. However i dont know how to do this in Net Beans. So i tried to do it from Command promt using command :
wscompile -gen:client -d build -classpath build config-wsdl.xml
here im getting Error:
error parsing configuration file: XML parsing error: com.sun.xml.rpc.sp.ParseException:10: XML declaration may only begin entities
Please help me out.
Many thanks in advance,
Kacee

Can i use the client generated using jdeveloper 11g to import into the oracle forms 10g, i.e., form builder 10g. Currently this is the version we have in our office.

Using message-style web service by a Microsoft client

Does anyone have a sample Microsoft client using message-style web service? BEA
does not provide one. I found MS client does not receive messages published between
2 calls to method "receive", while the sample Java client ConsumerClient.java
does.
ConsumerClient.java is like:
while(true){
Object result = method.invoke(null);
sleep(20000); // not in sample, added for my test
System.out.println(result);
My VBScript code is like:
Set SC = CreateObject("MSSOAP.SoapClient")
SC.mssoapinit "http://localhost:7001/msg/Receiver/Receiver.wsdl", "", "", ""
While TRUE
Res = SC.receive
WScript.echo "Res = " & Res
Res = ""
' do something that takes 20 seconds
Wend
I added 20 seconds between calls so I can publish a message between 2 calls. I
found the Java client receives the message but the VBScript client doesn't. Has
anyone else observed this?

Hi Kevin,
Thanks for your feedback.
Header support is planed for the next major release.

Hi Manoj,
Can you use SOAP header to pass session id accross instead of HTTP header? MS
SOAP toolkit 2.0 support access to SOAP header.
My app needs to use topic instead of queue. But as I said earlier, I can use MS
XML toolkit to access HTTP header. So I have a work around.
Thanks for all your responses with regard to this question!

Hum! i thought you were not able to receive message at all. now
i understood the problem. yes we are using http header to pass
session id accross, in the case of web service client who wants
to subscribe to JMS topics. I cant think of any other way to do
this. if you have any suggestions, i very much like to hear it.
for your application is it possible to use queues instead of topics?
we do not use http session information in the case of JMS queues.

Hi Manoj,
Your sample code is basically same as mine. It would also lose messagespublished
between calls to "receive" method.
I figured out what's going on. Undocumented by BEA, the web servicesends JMS
session ID in HTTP header along with first message. When client makessubsequent
calls to "receive", this ID must be sent back. I found this by usinga SOAP trace
tool.
Unfortunately, MS SOAP toolkit doesn't support access to HTTP header.So one has
to use MS XML toolkit to use message-style web service, when writingMS clients.

I have not tryed message style web services with MS soap toolkit.
I think the problem is because the WSDL for the message style
web service use xsd:anyType as the return type and MS soap is
not able to understand it. can you pls modify the xsd:anyType to
xsd:string (or someother base type) in the WSDL.
SC.mssoapinit can load wsdl stored as a local file. so it should
be easy to make this change.

'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.

How to prevent downloading wsdl in weblogic web service client

Hi,
I get a problem regarding weblogic web service client. My working environment:
weblogic server 8.1
Windows XP SP2
JDK 1.4
I use the weblogic tool to generate the client jar file from the wsdl file.
 <target name="generate-client">
 <clientgen wsdl="ACCESS.wsdl"
 packageName="xxxxxx.client"
 clientJar="${client}/${AccessClient_jar_file}"
 keepGenerated="true"
 saveWSDL="true"
 />
 <javac srcdir="${source}"
 destdir="${client}"
 includes="**/AccessClient.java">
 <classpath>
 <pathelement path="${client}/${AccessClient_jar_file}"/>
 </classpath>
 </javac>
 </target>
After that, I create a client java file to invoke the service deploy in the server.
public static void main(String[] argv)
throws Exception
 int transactionId = 100;
 int id = 1000;
// Setup the global JAXM message factory
System.setProperty("javax.xml.soap.MessageFactory", "weblogic.webservice.core.soap.MessageFactoryImpl");
// Setup the global JAX-RPC service factory
System.setProperty( "javax.xml.rpc.ServiceFactory", "weblogic.webservice.core.rpc.ServiceFactoryImpl");
AccessServicePorts ws = new AccessServicePorts_Impl(argv[0]);
AccessService port = ws.getAccessService();
// Resource - create
Resource resource = new Resource();
resource.setRES_CD("Create ResCo");
resource.setCODE_CODE("code_cod");
resource.setRES_TYPE("Resource typ");
resource.setCOMMON_FIELD(common);
AccessDefaultResult resultItems = port.createResource(resource);
System.out.println("createResource : " + resultItems);
I find that this web service client always issue 2 http requests to invoke an web service method deployed in server.
1st http reqeust:
GET /AccessEpol/EpolServiceSoap?WSDL HTTP/1.1
User-Agent: Java/1.4.2_08
Host: 127.0.0.1:8001
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive
the return result is the wsdl downloaded from the server.
2nd http request is the real web service request.
The question is how could I eliminate the 1st http request because it's really unnecessary. I use other web service client like Axis 1.x, Axis client never has the http request to download the wsdl from the server.
I read through weblogic web service document. It do mentions that put saveWSDL="true" in the clientgen ant task. the default value for saveWSDL is true already. I did try saveWSDL="false" also. None of them can eliminate the 1st http request.
appreciate for any answer my question?

Hi David,
thanks for the reply.
More or less I agree some points you mentioned above.
I did use Axis 1.x to test the inter-operability. The web service was developed in Weblogic 8.1 and is a part of an existing web application. It will be merged to existing application deployed in weblogic 8.1.
I also program the web service client to test the web service.
The implementation of the server and client will be handed over the project team and training for supporting or continuous development have to be conducted by me. So I don't like to use two types of technologies which will make thing complex.
I found this issue when I tried to protected the web service endpoint, eg http://localhost:7001/epol/service, using the web application Basic mechanism. The wsdl URL http://localhost:7001/epol/service?WSDL is also protected in this case. Unfortunately the username/password pair is not sent to the server when the weblogic client download the WSDL from the server. In this case, the client failed and throw exception.
