Web service, servlet, HttpServletResponse, Locale

Hello guys!
I have two questions:
- Can a servlet be a web service?
- For the next one, I supposed that yes... I'm trying to build a web service from a servlet and I get a strange error.
I simplified the code to the maximum, and it became like this:
public class PriceListServlet extends HttpServlet implements PriceListIF{
    public void init() {
     public void doPost(HttpServletResponse resp) {
          }and the interface is:
public interface PriceListIF extends Remote {
     public void init() throws RemoteException;
     public void doPost(HttpServletResponse resp)throws RemoteException;
}Cannot be more simple, can it?
When I type ant build, I get the following error message:
erreur : La classe java.util.Locale n'a pas de constructeur vide accessible public
which means:
error: Class java.util.Locale doesn't have public empty constructor
I did a few tests, and if I put HttpServletRequest instead of HttpServletResponse, it works.
If the doPost method doesn't have any parameter, it works!
So there's a problem with HttpServletResponse...
Does anyone know what's Locale got to do with HttpServletResponse????
Thanks for your help

Soap Router versus Web Service Servlet

Hello:
I am trying to understand the fundamental difference between a SOAP Router versus
Web Service Servlet?. In websphere there is a concept called WSG(Web Service
Gateway) on which we can configure an handler to intercept the incoming soap requests.
But in weblogic I do not think we can configure any handler on Web Service Servlet.
So I think for this very purpose you have this soap router right ?. If this is
correct then does the soap router will forward the call to the Web Service Servlet
which implements the soap engine.
Please clarify,
Thanks,
Vijay

Hello,
Right, today there is not a global handler that can be configured;
however you can do servlet filter or check out an early access SOAP
Router[1] from Manoj.
Could you give us a snapshot of your use case?
Thanks,
Bruce

Ignoring Http basic authentication header in wls 7.0.sp2 web service servlet (weblogic.webservice.server.servlet.WebServiceServlet)

Hi!
We need to implement authentication using our own methods, and the authentication
information is provided to the web service implementation in a basic authentication
header. The problem is, that the servlet
weblogic.webservice.server.servlet.WebServiceServlet, which handles web services
in
wls 7.0.sp2, always attempts to perform authentication, if the header is present.
Is there any way to circumvent this, because we want to implement authentication
on our own?
I already know two workarounds:
The best would of course be to implement a custom security realm for our own
authentication system. This is not an option, implementing an own security
realm is overkill for this specific web service.
The other way would be to route the requests by way of a custom servlet, which
would
remove the basic authentication header, and put the authentication info in custom
headers, such as x-auth: <user:password>, or smthng similar, and after successful
authentication, make a call to bea's servlet weblogic.webservice.server.servlet.WebServiceServlet.
But still, I'd like to know if there is any way to tell bea's servlet to ignore
the basic
authentication header?
Oh yeah, by the way, this is URGENT, as always. (really!! ;)

Currently there is no option to turn off security check.
I think you can use a servlet filter mapped to the URL
of your service, instead of a proxy servlet?

Web service call - works locally but not on mobile?

Hi,
I have a web service call (the service is hosted on the cloud so it's an external, permamnent domain) which works fine when I'm testing it locally using the Flex Buritto built in emulator or directly using my browser.
But when trying from an android phone (tried a few of them - nexus one, nexus s and galaxy tab) the service is being called but never returns anything.
Is there a good way to trace to call / understand the problem?
Thanks,
Nir

Oh. well that would explain alot of it. its not a stupid question we are all learning. You have to put a crossdomain xml in server on the root directory. there are alot of different ways to implement it.
this should point you on the right direction.
http://www.adobe.com/devnet/articles/crossdomain_policy_file_spec.html
here is a very basic format basically allowing anyone to call my service.
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy
SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*" />

Client triggers Web Service servlet

Hi,
I'm new to java enterprise app. I have to develop a web service which listens to incoming soap info and triggers a servlet to be displayed on the screen where the web service is installed. And the servlet must show the message received from soap. The problem is that I don't know how to trigger the servlet. Can anyone help me please? Thanks in advance!.

Hi Martti,
I am looking for something similar , were you able to get this to work?
Also, how did you configure the identity assertion provider?
Any help would be appreciated

Web Services - Servlets vs EJBs

Hi,
Looking for any suggestions about the benefits of using either servlets or EJBs as web service endpoints. Very early in the design of any application, I wish to expose my business logic components as web services, is there any particular benefit to using a specific approach (i.e. using either EJBs or Servlets as the end points of the web services exposing the business logic)?
This is a totally new application so I have no considerations towards reusing old EJB code, etc. My initial thoughts favour using servlets, if only because it reduces the complexity / resources required for the application server (i.e only Web-container required, rather than Web & EJB container).
Any thoughts please?

Why do Servlets not scale as well? Surely they are
more "lightweight" than an EJB (which has all theRMI
overhead), and wouldn't it ultimately be down tothe
underlying app server anyway?Right, but servlets are just HTTP request listeners.
They aren't components, they aren't transactional,
they don't handle persistence, they don't have
naming services, they don't have queuing services.
The EJB container offers you a lot.
With that said, it's not just a choice between
servlets and EJBs. You can use POJOs and avoid EJBs
altogether if you do it right.
Or choose the best of both worlds and mix 'n match as needed.
Noone forces you to choose one over the other (at least not for any technical reasons, I'm not diving into corporate politics here).
My thought was that web services were a better wayto
expose business logic than EJBs, but if there some
solid reason why this isn't the case I like toknow.
Web services - lightweight? Maybe that's true of
REST, but certainly not SOAP. There's an argument
that says services are more heavyweight than EJBs,
because all the XML on the wire is an expensive
protocol.
SOAP is heavy on the network, but it's essentially a rather thin layer on top of other services (if properly architected).
For example we have a SOAP layer exposing a Spring application which proxies an EJB architecture.
Next to that SOAP layer sits a traditional web application (servlets) which itself has a Spring application sitting on top of it for demonstration and testing purposes.
And then there's an SDK allowing direct access to the Spring layer (and thus almost direct access to the EJB layer).
That's the beauty of a true open architecture, each component can be built on top of another and the component underneath can function just fine without it.
Look into Spring:
http://www.springframework.org
It's a lighter alternative to EJBs, and good plumbing
for any Java EE app.While Spring can serve as an alternative for EJB in places where EJB are overkill it's of course not in competition with it.
Spring is a service layer, making use of other technologies (like EJB, like AOP, like ORM) to provide data and other services (like Struts, like JSF, like JSP) to provide that data to requesters.

Force web service servlet to use http 1.1

is there anyway to force a web service deployed to oc4j standalone 9.0.3 to service many calls over one http connection? there doesn't seem to be any documentation to that end. Thanks, Ki

But, I want to know which Framework will provide
better performance?
better than what?
Also I want to develope the web service as a standard
one andeach has it's own quircks and implementation details. Each should be able to generate and accept the same SOAP messages though if you implement them properly.
It should be able to provide bulk data exchange.
That will depend in large part on your hardware.
Please suggest a web service framework
(Java-based) which will give better performance.again, better than what?
Better than messenger pidgeons?
Better than swallows (European or African)?
And if so, how heavy would the message capsule be? 2 swallows may be able to carry a coconut together, holding it on a piece of string.

Web Service - Cannot Deploy on Local OC4J

We get the following error when trying to deploy the following code as a web service to the local OC4J.
The parameter of domDoc of type oracle.xml.parser.v2.XMLDocument cannot be serialized into XML, and no custom serializer has been defined for it.
All we want to do with this service is connect to the database and return the results of the query in XML. We have tried a string, but it returns a string of XML and we need it to return the XML.
The code compiles, runs, and looks as though it is returning what it is suppose to if we write the return out, but the code will not deploy as a web service.
Thanx so much
Pam

return(0);
}

Hi Pam,
It is using Element as the method return that is causing the problem. As you've seen this means that the Data Control has no concrete schema types to associate with the fields so it fails.
I have a couple of possible workarounds.
1. Is it a requirement to write your SQL query in the method? Perhaps they are to be dynamic?
If not, have you considered using the database to do the query and publishing that as the service. This would work around the problem. You can use JDeveloper to do all of this if you 'wrap' the query in a PL/SQL package in the database. Then use the 'Web Service from PL/SQL Package' wizard to generate the web service including wrapper Java classes for the package and DB connection/mgmt classes.
Or you can publish the actual Query as a service - using the command line (unfortunately you can't use JDEV to do this)
2. You mentioned the XSD for the query - if you have that then you can use a custom serializer and map your XSD to the return type of your method - the org.w3c.dom.Element class:
a. if your web service is already generated - open properties (Web Services Editor)
b. go to Custom Mappings page
c. click Add
d. for Java Class type in org.w3c.dom.Element
e. for XML Qualified Name add your XSD
f. add your serializer class - here is one I made earlier!
package project3;
import java.util.Map;
import javax.xml.namespace.QName;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPException;
import oracle.webservices.SOAPUtil;
import oracle.webservices.databinding.SOAPElementSerializer;
import org.w3c.dom.Element;
public class DummyElementSerialiser implements SOAPElementSerializer
public void init(Map map)
public SOAPElement serialize(QName qName, Object object)
try
return SOAPUtil.toSOAPElement((Element) object);
catch (SOAPException ex)
return null;
if you're generating the service from scratch this same mapping page comes up as part of the wizard
Now you should be able to create your data control

XI and Web services

Hi guys,
I want to exposed XI message intefaces as a web service on a local uddi repository . Is it possible to expose Outbound intefaces from SE80->Enteprise Services , I am sure about Inbound intefaces but not out bound .
Any suggestions or help appreciated.
Regards,
Keith

Keith,
In your ID > tools> Define Webservice and you can expose your Outbound interfaces as webservices.

Problem Deploying Web Services

I have created a Web Service based on a pl/sql function in my database. I used the JDeveloper (10.1.3.2.0) wizard to created the web service. I used the J2EE 1.4 (JAX-RPC) Web Service wizard. The web service works fine when I access it using the OC4J container built into JDeveloper. When I deploy the Web Service to our Oracle Application Server 10.1.2.0.2 on Solaris I receive the following error when I try to access the Web Service:
Servlet error: Error instantiating servlet 'ticketwsSoapHttpPort' (servlet class not found, make sure it exists at /u01/app/oracle/midtier/j2ee/OC4J_APPS/applications/ticketws_jax/ticketws_jax/WEB-INF/classes/ticket/TicketwsUser.class, in a jar in /u01/app/oracle/midtier/j2ee/OC4J_APPS/applications/ticketws_jax/ticketws_jax/WEB-INF/lib/, in an orion-web.xml specified classpath or global server classpath)
I checked both paths mentioned in the error message on the server. All files seemed to be there.
Any insight into this issue would be much appreciated.

Hi user493481,
I have developed a PL/SQL Web Service using JDeveloper, it is working fine on local instance, time to deloy on Application Server (Apps 11.5.10.2),
could you post the deploying steps...
Thanks in advance,
Rao.

Hi,
maybe you should see the settings for the ServicesRegistrySiService too. Under nwa->SOA.
I am not sure, but the error seems like not able to use the ServicesRegistrySiPort, which is to be authenticated against.
It is then used for retrieval of web services and publishing to the registry... i suppose.
I am not sure though.

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 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,

Web Start client for two Web Services

Hello.
I wrote a client application that uses two different web services.
Both web services are created using Basic Authentication. They have different user_names and passwords, but must be deployed on the same application server. I must invoked methods of these web services one after another.The problem occures when I invokes mehods of second web service. No matter which of service would be first or second. The problem occurs on second calling. I got this exception:
EXCEPTION: java.rmi.RemoteException: HTTP Status-Code 403: Access to the requested resource has been denied; nested exception is:
     HTTP Status-Code 403: Access to the requested resource has been denied
     at com.softlets.insurelet.security.InsureletSecurityServiceSEI_Stub.login(InsureletSecurityServiceSEI_Stub.java:89)
     at com.softlets.insurelet.test.TestRefundPolicy.main(TestRefundPolicy.java:61)
     at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
     at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)
IMPORTANT: Everything worked fine until I started to install this application using Java Web Start.
MY ASSUMPTION: It's likely to me that web start executes my application in some environment where it caches the first web service's username and password and applies it to the second web service. Because, if I run both web services on my local machine and set ENDPOINT_ADDRESS_PROPERTY to different values (first - localhost:8080, second - 192.168.0.21:8080) everything works fine.
CODE FRAGMENT:
public static void main(String[] args) {
try {
String user = "test"; String pass ="test";
String host = "http://192.168.0.21:8080/insurelet-p/insurelet_p";
Stub stub = (Stub)(new Insurelet_policies_Impl().getInsureletPoliciesServiceSEIPort()); stub1._setProperty(javax.xml.rpc.Stub.ENDPOINT_ADDRESS_PROPERTY, host);
stub._setProperty(javax.xml.rpc.Stub.USERNAME_PROPERTY, user);
stub._setProperty(javax.xml.rpc.Stub.PASSWORD_PROPERTY, pass);
InsureletPoliciesServiceSEI ws = (InsureletPoliciesServiceSEI)stub;
String officeid = "test1"; String operatorid = "test2"; String mct = "1";
// FIRST WEB SERVICE CALLING
boolean result = ws.makeRefund(officeid, operatorid, mct);
String suser = "test"; String spass ="test";
String shost = "http://192.168.0.21:8080/insurelet-s/insurelet_s";
Stub stub1 = (Stub)(new Insurelet_security_Impl()).getInsureletSecurityServiceSEIPort();
stub1._setProperty(javax.xml.rpc.Stub.USERNAME_PROPERTY, suser);
stub1._setProperty(javax.xml.rpc.Stub.PASSWORD_PROPERTY, spass);
stub1._setProperty(javax.xml.rpc.Stub.ENDPOINT_ADDRESS_PROPERTY, shost);
InsureletSecurityServiceSEI ws1 = (InsureletSecurityServiceSEI)stub1;
// SECOND WEB SERVICE CALLING
OperatorTO to = ws1.login("softlets", "admin", "admin"); // EXCEPTION
ENVIRONMENT: Both web services are deployed in a single enterprise application on Sun Java System Application Server 8.1.
Java version: 1.5..0_02

In case anyone's search leads them here, I've posted the solution at:
*[http://www.pby.com/general.nsf/webarticles/dominowebservice01]*
It is an exhaustive article (not "Hello World"!) that goes through several versions of the web service and client - hopefully explaining all* pieces of the puzzle:
~ web service code,
~ WSDLs
~ schema
~ thoroughly-documented clients that do and do not use JAXB
~ ... that use generated artifacts
~ ... that customize existing POJOs
~ the SOAP messages generated in each direction
~ the necessary JAXB annotations
~ explanations of how the code works
~ explanations of how namespaces affect the code
~ on and on and on...
My constant goal was to write an uncomplicated solution that uses as few artifacts (two) and annotations as possible. The end result is a small, fast JAX-WS 2.0 client that uses JAXB to invoke and consume a secured Domino 7 (1.4.2 JVM + AXIS) web service, using RPC/literal SOAP messages.

9.0.3 two web services questions

OK, I'm trying to get web services to work and having two problems.
The (hopefully) simple one: I want to install a web service on the local OC4J, and I can't seem to get the connection to work. Getting connection refused. Not sure why. Didn't see any problems like this with 9.0.2, but we mostly installed them on 9iAS.
The more complex one: I started working with a PLSQL web service. While I can't execute it yet (see above), I can create one with a simple return type. For example, something like f_seq_to_name (i_seq in number) return varchar2. And the stub is pretty easy.
But if I want to return a rowtype, for example
f_seq_to_row (i_seq in number) return facility_table%rowtype,
the routine is grayed out because JDev decides there is an out parameter of type "null". I could explicitly include each individual parameter, but that seems like a waste of developer effort. And this happens for both rowtypes and ref cursors, so it will be pretty hard to move any significant amount of data. So am I missing something, or is this a bug? If it's a bug, will it be fixed in 9.0.3 production?
Of course, I can go over to BC4J and try this there with view objects. But I'm looking to see which of the tools are usable.

Here is some pointers that might help:
1. A PL/SQL Web Services Tutorial using Oracle9i JDeveloper 9.0.3 including the setup necessary to configure OC4J. As you will see you don't have to actually create a SOAP connection in JDev; for PL/SQL you simply need to have an app server connection as per the writeup. See:
http://otn.oracle.com/tech/webservices/htdocs/series/plsql/content.html
2. To see what data types are supported for PL/SQL take a look at:
http://otn.oracle.com/docs/products/ias/doc_library/90200doc_otn/web.902/a95453/plsqlservices.htm#1030045
ROWTYPE and REFCURSOR are not supported. This does not appear to change between 9.0.3 preview and 9.0.3 production. There are some other approaches to consider, though your milage may vary. For example, VARRAYS and abstract datatypes are supported - you can see the ADT support in the above tutorial and try VARRAYs by tweaking it to return an array of employees rather than a single employee.
Hope this gets you going.
Mike.
