JAX-WS Web Service with XFire Client

I wrote a simple web service and client using XFire. However the server now needs to be JAX-WS. I wrote a simple service using NetBeans but I can't seem to get it to work with XFire. JAX-WS doesn't seem to like the SOAP XFire is sending it and the parameters passed into the web method are nulls instead of the intended values.
Here is my web service:
package org.me.hi;
import javax.jws.WebMethod;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;

import javax.jws.soap.SOAPBinding.ParameterStyle;
@WebService(name="HelloWS", targetNamespace="http://hi.me.org")
@SOAPBinding(style=Style.DOCUMENT, use=Use.LITERAL, parameterStyle=ParameterStyle.WRAPPED)
public class HelloWS {
 @WebMethod(operationName="add", action="")
 @WebResult(name="return", targetNamespace="http://hi.me.org")
 public Integer add(Integer a, Integer b) {
 if (a == null)
 System.out.println("a is null");
 return null;
 if (b == null)
 System.out.println("b is null");
 return null;
 System.out.println("a: " + a + " b: " + b);
 return a + b;
}Here is the WSDL:

Consume a web service from JME that returns an image

Hi,
I have a web service that returns an image in base64binary format, but when i use the wscompile tool to generate the stub i get an error becuase seems that JME does not support base64binary -> byte[] convert. My question is: How can i return an image from web service to consume from JME?.
Thanks in advance.
Bruno

I tried this and works fine, but i see this like a workaround instead of a solution. Do you know why JME doesn't support this type of data? I think that is weird because i don't see a limitation on JME for use it.
Thanks for repsonse.

[ANN] XINS 2.1 open source Web Services framework release

XINS 2.1 Web Services Framework has been released.
XINS is an open source Web Services Framework based on simple specifications of the Web Service in XML and
generation of code and documentation from the specification.
The generation includes Client JAR with its Javadoc, Server side template with its Javadoc, documentation in OpenDocument Format,
documentation in HTML including the test forms, WSDL file, unit tests (JUnit) and stubs.
The Web Services accept several protocols including REST, SOAP, XML-RPC, XML, JSON Yahoo! and JSON-RPC.
What's new:
* Start the API with java -jar <api name>.war
* Improved generated specification in OpenDocument Format
* Include/exclude calling convention with ACLs
* New calling convention that maps SOAP request and response as the wsdl2api command mapping.
* Smaller generated build.xml
* Added possibility to include other runtime properties files
* The runtime property location can be a URL
* Swing Graphical User Interface
* New tools: emma, glean, webstart
* New target: javadoc-test-<api name>, javadoc-apis
* Bug fixes and small RFEs

I recommend you implement your web service with JAX-WS 2.0
Axis (both version) are good but why do you want to use something that is not included in JEE API, when Java provide same thing with better performance.
personally try to prevent non standard technologies despite they can be better than core java implementation sometimes.
I don't know Xfire.
the good:
-JAX-WS performance is better than axis,
- you can create your web service simply with annotation.(this means write class and then make it as a service easily)
- support every kind of service invocation(callback,Asynchronous,...)
- architecture is nice (you can operate on SOAP level)
the Bad:
- It is JEE 5 or JSE 6 dependent.
- there is seriously lack of documentation and examples for it, on java web sites and internet.

Process for adding a boolean option to the web service API

Hey guys,
Here's a little background:
I'm currently working on adding an optional "strict" mode to some of the unmarshalling functions in SchemaMarshaller that will throw exceptions when receiving bad data for certain fields, and also improving the date handling while I'm at it (I want null instead of mangled dates when receiving bad data when strict mode is off).
This is for my benefit at the moment as I'm tired of spending time debugging Flex code when XFire and Oracle are spitting out rubbish (like empty xsd:DateTime nodes, DateTimes in xsd:Date nodes, etc) - but I'm sure other people would like to use it too while we don't have a response validator, so I'd like to do it in a way that I can submit as a feature request (with patch) on Jira.
My questions are about the procedure for stuff like this- where should this option be made public in the API, and who would I talk to about it? Or would it be best for it to always be strict? - That's how I'd like it :) Perhaps it should just log errors when it encounters bad data?
This is the first thing I'd like to "add" to the SDK rather than a simple bug-fix, so I just want to do things in a kosher manner. Sorry if I come across like a total noob :)
Cheers,
-Josh

Hey Josh, I'm swamped at the moment but appreciate your interest and your contributions to Flex and WebServices thus far. I'll try and get some time to look into your specific request and what you're hoping to do at the code level, but to answer your question about test cases, you should consider the NIST testsuite for XML Schema datatypes. BlazeDS has historically maintained the WebService implementation, so it appears their test case for NIST based schema tests starts out here (and refers to many data type test cases in the /nist subdirectory). http://opensource.adobe.com/svn/opensource/blazeds/branches/3.0.x/qa/app s/qa-regress/testsuites/flexunit/src/tests/flexunit/xml/NISTXMLSchemaTes t.as Pete ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of Josh McDonald Sent: Tuesday, July 08, 2008 8:21 PM To: [email protected] Subject: Re: Process for adding a boolean option to the web service API A new message was posted by Josh McDonald in Developers -- Process for adding a boolean option to the web service API Yeah I knew it'd have to be somewhere outside of SchemaMarshaller, as it's [ExcludeClass] anyway so end users don't see it, nor is it documented in the api docs.

Didn't think about having it settable on operation as well though, so thanks for that :) Anybody know a good source of valid values for various XSI types (date and DateTime mainly) for testing purposes?

I'd then also add an option to the WebService class itself, and basically in the Operation it should see if it has its own value set and if not check the value on the WebService. We do this for a couple of other flags too I think. End users in general wouldn't look at any classes other than the WebService and maybe the Operation classes, so asking them to set options on the schema classes themselves probably wouldn't work.

Are the WLS 9.1 Web Service Ant Tasks ready for prime time?

I am trying to create a Proof of Concept (POC) for Enterprise and B2B Services at Wendy's Int'l, Inc.
As part of this POC, I created a WSDL for an in-house service and then used the wsdlc and jwsc Ant Tasks to translate this WSDL to Java classes and ultimately (I hoped) a deployable services.
In this document, I describe the issues I encountered setting up what I consider to be a simple POC.
I'll try to attach my WSDL file and build.xml so you can follow along.
I'll also try to attach my CSS file so you can compare how the generated WSDL appears in the Browser to the way I want it to appear.
If attachments are not allowed on these forums, then I will wait and see if there is interest in those documents before I paste them under this topic.
Some preliminary information about my environment.
Environment:
 Windows XP Pro SP2
 WebLogic 9.1
 Java 1.5.0_04
Service Name:
 AppRelease
Note: If I modify my WSDL (perhaps to add a new Operation or to change the definition of an element) and run wsdlc again, the AppReleaseSOAPPortImpl.java file is overwritten For this reason, I implemented my service logic in a class called AppReleaseServiceImple.java.
Now, for the issues.
1. Bug:
In the WSDL generated by wsdlc, the wsdl:part child of the wsdl:message tag is erroneously prefixed with a colon.
This occurs whether or not I specify a prefix for the http://schemas.xmlsoap.org/wsdl/ namespace.
Work around: Extract the wsdl from the jar file, fix it and add it back into the jar.
2. Bug:
In the WSDL generated by wsdlc, the wsdl:input and wsdl:output children of the wsdl:operation child of wsdl:portType tag are erroneously prefixed with a colon. Like 1 above, this occurs whether or not I specify a prefix for the http://schemas.xmlsoap.org/wsdl/ namespace.
Work around: Extract the wsdl from the jar file, fix it and add it back into the jar.
The error message generated by Bugs 1 and 2 is not helpful in diagnosing the problem:
[jwsc] Error at line:46 col:7 ':' expected [?! -- [CDATA[ ]
3. Bug:
In the WSDL generated by wsdlc, the documentation elements have all of my html elements stripped out, as well as my xhtml and wsdl namespace references. This completely negates one of the best features of the documentation tag, being able to present the WSDL in a browser as a nicely formatted, human friendly document which is also the underlying WSDL that can be viewed when the person views the source document.
I label this as a bug because it greatly reduces the functionality of the resulting WSDL.
4. Annoyance:
The WSDL generated by wsdlc has all of my comments stripped out, except the comments in the xsd:schema section of the wsdl:types element. I would prefer that all my comments be left in the WSDL, but if comments must be stripped out then I think all of the comments should be stripped out.
5. Annoyance:
The WSDL generated by wsdlc has my CSS specification stripped.
Work around: I donâ€™t know if adding the CSS back will do any good because I have not yet created a deployable service (see the last issue below).
6. Annoyance:
The WSDL generated by wsdlc has different namespace prefixes than the ones I specified for my application's namespace and for the http://schemas.xmlsoap.org/wsdl/soap/ namespace.
Work around: Perform a find/replace on namespace prefixes "s0" and "s1" to return them to my prefered values.
Another thing I can do at this point is simply replace the generated WSDL in the jar file with my original WSDL. This would address issues 1 thru 6 above.
7. Annoyance:
The java source files created by wsdlc are put into a jar file. This makes it annoying when working within a traditional IDE like Eclipse because there is no way to reference the source files within the jar as working source.
Work around: Extract the source files from the jar and identify the resulting directory structure as part of the source structure of the project.
8. Bug:
The jwsc task complains if the same parameter name is used in multiple operations. I received the following Errors from jwsc:
[jwsc] C:\IDE\workspace\Acre-WL9.1\AppReleaseSOAPPort.java 0:0
[jwsc] [ERROR] - Parameter element "{http://acre.services.wendys.com/AppRelease/}garRequest" is not unique across document/literal bare WebService.
Since the operation names are unique, I see no reason to also require uniqueness in the parameter names used by those operations.
Work around: Use unique element names for the input parameters of the services operations.
9. Bug:
Once items 1, 2 and 8 above are taken care of, jwsc fails with the following error:
java.lang.AssertionError: java.lang.ClassNotFoundException: weblogic.j2ee.descriptor.ApplicationBeanImpl
This seems to be due to the weblogic.jar file not being in the System Classpath.
However, I should note that when I set verbose="on" and debug="on" in the jwsc ant task, there was a message from the task which stated "[jwsc] [search path for class files: [big freakinâ€™ jar list]". In the big freakinâ€™ jar list, I did find weblogic.jar and weblogic.jar has the required ApplicationBeanImpl. This indicates to me that the jwsc task does not fully honor either its classpathref attribute, nor an embedded classpath element.
Work around: Make sure the weblogic.jar is in the System Classpath.
10. Bug:
I fixed bug #9 by running a setDomainEnv script and then ran my ant task. This time I received the following output:
ant build-serviceBuildfile: build.xml
build-service:
[jwsc] 1 JWS files will be processed.
[jwsc] Processing JWS: C:\IDE\workspace\Acre-WL9.1\src\com\wendys\services\acre\AppReleaseServiceImpl.java
[jwsc] JWS: C:\IDE\workspace\Acre-WL9.1\src\com\wendys\services\acre\AppReleaseServiceImpl.java Validated.
[AntUtil.deleteDir] Deleting directory <some temporary directory>
BUILD FAILED
java.lang.ExceptionInInitializerError
At this point, I am completely stymied about how to proceed.
I wonder what new issues await once this 10th issue is addressed.
Really, is this tool set ready for prime time?

Sorry to hear you are having so many issues with using the WLS 9.1 web service Ant tasks, inside of Eclipse.
I generally create a User Library for the couple weblogic jars needed, and use it (the User Library) in my Eclipse projects that I create JWSes in. 
I also have a separate WebLogic Library in Eclipse (actually 2 libraries since I work with WL 8.1 and now WL 9.1). As you may know, one of the long-standing issues with the Ant integration within Eclipse is the fact that Ant, being an External Tool, does not receive the Project-specific Paths/Libraries. However, since most Java-relevant Ant tasks can take classpath and classpathref attributes, this is usually not an issue. In the case of the BEA-supplied wsdlc Ant task, it is apparent from the verbose/debug console output that wsdlc can see the jars in its classpathref, but it ignores those references when resolving class references and instead only uses the system classpath.

I've only needed the weblogic.jar and xbean.jar, not all the ones you mentioned in an earlier thread of this post. 
I have not tried to winnow down exactly which jars are required. I simply included all the jars that exist and were added to the system classpath by the setDomainEnv.bat file created by WebLogic 9.1.

Afterwards, I create an Ant Builder to build the JWS Web Service EAR, as opposed to fiddlin' with Eclipse. 
I too use Ant to build my deployable archives. Eclipse is simply my IDE of choice. I validated that all the issues I listed occurred when running Ant from the command line.

If you are interested in how I do it, send me an e-mail (to [email protected]), and I'll send you a zip of one of these JWS projects. The build.xml script for the project, takes care of a lot of the "annoyances" you mentioned, one of which I think is not accurate. I have never had a situation where the wsdlc Ant task "overwrote" my XXXImpl.java file.. 
Since I'm doing a POC to determine how we want to proceed with developing Web Services and an SOA in general, I tried to perform the same tasks using Axis 2 1.0, the WebLogic 9.1 tools, and XFire 1.1. Overwriting the Impl class is a common failing in the tools which take a WSDL and create Java source files for all three frameworks.

Try my scenario. Add another operation to an existing WSDL, and run the wsdlc Ant Task. The old IMPL class will be over-written.

Because of this, I have a separate Impl class and I make sure that all its methods and annotations match the methods and annotations in the Skeleton Impl class created by wsdlc.

Maybe that's because I use the <exec> Ant task with jar.exe (the xvf options) in my build.xml, to only get what I need out of the .jar/.zip the wsdlc generates. I'm typically only interest in the interface class that my XXXImpl.java file needs to implements, because I use XMLBeans for the input args (and return values) of my web service operations. 
Perhaps. I am not using XMLBeans in any of the three frameworks because the resulting service seems to be lighter-weight in all three frameworks if XMLBeans is not used. I'm sure there will be scenarios where XMLBeans is preferred, but I have not encountered that case in this POC.

Mike Wooten

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.

Problem with web service that returns an object with a String that have som

Hi everybody:
I have a problem with a web service I am doing, I have made a web service that returns a collection of objects, the objects have a set of properties, there is one property that is a String,this property consists in a text fragment that could have some characters that are considered special in XML like &, <, >, " and that's why when I execute the service from a client an exception is thrown:
{code}

I know that this is happening because special characters are sent by the soap message but I don't know how to solve this problem.
How could I avoid this exception ?
I hope you can help me.

Hi,
BPEL and BPEL PM do not have a good support for SOAPENC-Array: it would be very difficult to create such an array in BPEL or to receive it and manipulate it.
The (unfortunately very intrusive) work around is to change the WSDL of the service to use a XML type defined using XML schema. This is all the more painful that JDev 9.0.4 does not have strong support for complex types.
In general though, I would highly recommend this best practice:
1) Start by define the WSDL contract first
2) Then generate the server side skeleton to implement it
3) Use BPEL as the client to this contract.
By starting with the contract first, you make sure that 1) your interfaces are clean and coarse grained.
2) things like java objects, sessions, etc to not leak through the interface (which would be the worst thing that could happen because it would closely link the client and the server.
Sorry for not being more helpful. This will get radically cleaner in Oracle AS 10.1.3.

HTTPS web service connection errors

We have a Java web application that accesses a Web Service using https. Last week the hosts of the web service installed a new signed SSL certificate. As soon as they installed the new certificate, our Java web app stopped working. When we try and access the web service via the web app we get the following error:
2008-05-16 20:20:07,226 ERROR [org.codehaus.xfire.transport.http.HttpChannel] - javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
2008-05-16 20:20:07,237 ERROR [grantee.GranteeServlet] - Could not invoke service.. Nested exception is org.codehaus.xfire.fault.XFireFault: Couldn't send message.
The Operating System is Solaris, The Web application server is Tomcat 5.5, and the JDK java version is "1.5.0_05".
The confusing part is that we can test the web service using SOAP UI. We can access the webservice that way. So the web service seems to be working correctly, but our Web Application can't seem to connect to it.
Any ideas?
Thanks in advance, and let me know if you have any more questions.

Hi Aaron,
You may want to try formatting the cell of "ModifiedOn" to a TEXT format instead of date to get yyyy/mm/dd formatting to appear.
It seems that Xcelsius automatically converts any type of date-specific formatting (as specified from Excel) to a date serial, which is what you are seeing here.
Hope that works.

Call web service using Java code

Hi all,
Sorry if this question sounds stupid. I am new to web services.
I am having a web service written in oracle, using soap-api. I want to call this web service in Java application, parse the result and save it in the database.
Can anyone please guide me on this or give me some related link. I tried searching on google, tried to implement some of the solutions I got in search results, but it was not that helpful.
Waiting for your help. Please guide me through this.
Waiting for your replies. Thanks in advance.

Hi all,
From my java code, I tried giving
String testStr = service.search("and formatted_address like '%Test House%'");
This service method is defined on my SearchPortType.java file. This and the searchClient.java, as I mentioned earlier are auto generated files by myeclipse IDE. I gave WSDL URL, which generated these two files.
This helped me invoking the service, but it gives me an exception as below:
Exception in thread "main" org.codehaus.xfire.XFireRuntimeException: Could not invoke service.. Nested exception is org.codehaus.xfire.fault.XFireFault: Couldn't send message.

Enabling web services in OIA throws error

We have OIA 11gR1 installed in our environment and we are enabling web service in OIA.
As per Oracle Docs, we have downloaded and installed wsdl4j-1.6.1.jar and placed in OIA_LIB.
I have modified the web.xml to enable the config related to web services.
Post deployment of OIA application and OIA server restart, we are encountering the below error:

Which is the BEST Java Web Service Framework to use?

Hi all,
I'm a beginner to Web Services.
I am planning to implement java web services to make the communication between java(Tomcat Server) and C# client.
I found list of web service frameworks like,
1. Apache Axis,(POJO,Axiom)
2. JSON-RPC,
3. Java Web Services Development Pack ,
4. Web Services Invocation Framework,
5. Xfire,
6. XML Interface for Network Services. ...
Please do reply me that which web service framework will be efficient to use.

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.

Which is best web service framework for developing web services in Java?

Hi Friends,
I want to develop web services using Java 1.5.
But I am in confusion with different frameworks provides to develop WS.
Like
1) Apache axis
2) Java Web Service dev. Pack
3) JSON-RPC-Java
4) Web Ser. Invocation Pack
5) XFire
Can some one guide which framework should I use?
OR where will i get useful comparison between this frameworks?

Hi,
Personally I have used:
1. XFire
2. Apache Axis
3. Java Web Service Pack
My personal opinion / .02 cents?
1. XFire is awesome and very easy to set up and get running. They also have a great community / mailing lists. We use it in some production systems and it runs great.
2. Apache AXIS 1/2 made me want to dive out the window and go splat just short of the double yellow line on the road. Pain in the butt to set up and get running. Way too complex. Really bad docs / tutorials / support.
3. Java Web Service Pack - I really prefer NetBeans 5.5 and the JWSP. Easy to build services, cohesive enviroment. You can get the job done.
That's my two cents.

Netbeans Web Service GUI

Hi everyone,
I'd really appreciate any help on this matter. I'm trying to build a GUI for a web service. I want the GUI to accept input from the user which is converted to a soap request which is then sent to a server to be processed, and a response is sent back. I want to format the response so that it is readable by the end user. So basically, the server does all the processing; all I have to do is produce the soap request, send it by soap over http and then parse the response from the server.
I've made a project in Netbeans with WDSL, BPEL mapper etc. I don't really know how to contact the server to send the soap request.
Could someone please give me some guidelines on how to do this? I'm completely new to Java but I have a basic understanding of WSDL, XML schema etc.
Again, any help much appreciated,
Ruth

hey sabatier,
I haven't done webservices with netbeans, but I have done it with Eclipse (using xfire), and here is what I can tell you.
Let's say you create a webservice that takes an string input. On the client side, after the user puts in whatever string this is, you build the call to the webservice by using the webservice stubs. It will then wrap the user input to the soap message and send it. It should be as simply as that. With all the tech out today, you shouldn't have to write your own soap messages.
Whatever your webservice returns, if it is a string result, again, it should be returned to you only as a string. All the work of extracting the return from the soap message should happen under the hood.
