Implementation oF messageQ in java web services

Hi All,
Can any one tell me how one can implement MSMQ in java for handling web service request and response.
Thanks in Advance
Harshal

I am really thankful, for your response.
Ans
1) Web services are implementted in java using apache cxf 2.2.3 framework and It is running on weblogic werver 10.3 and 10.3.4.
2) No, I know your according to call back service concept but instead of this we are having WSDL URL where we need to send response back.
3) Yes, currently we are processing in thread based processing (i.e. for each request we are creating one thread which will process it completely), Which may causes database dead lock, so to remove this we are willing to process requests sequentially.(using MessageQ)
For my knowledge, I am having little confusion that Is MessageQ and JMS are same?
Thanks,
Harshal

Newbie question to java web services....

hi,
I used to be a .net programmer for a few years, and am have done web services in .net.... (using IIS, of course)
And i moved onto Java side recently - and am pretty new to tomcat / axis..etc..
I looked at the netbeans ide tutorial, and it covered on how to create a web services and a client using the IDE - with that is with the sun app server. Since I want to stick with Tomcat (which is a servlet container, i believe), the compilation complained that the HelloWSImpl.java is not a servlet, and will not let me run the web app. I have tried the WSDP 2.0 tutorial as well, but I first got the FastSetsource.jar not found? Then I got some other classes not found..etc... so, until now - i still am not able to create a web service, and a cliet to talk back and forth.
I have the following questions..
1. I am confused that how come tomcat itself is already a webserver, why would people use it on top of apache http server, which is another web server?
2. To create a web services, (I am thinking of the .net web services that i have done - that once you deploy it with IIS, and you browse to that service, if the function takes 2 parameter, there will be 2 textboxes waiting for you to put data to, then once you post - the xml response will come back...), does java allow front end interface automatically like that in .net? Or you have to code the JSP pages to include those textboxes yourself, and do a manual post to the web services address?
3. Are there any book out there, explains how to use tomcat for webservices? I have looked thru some of the java books that talks about web services, they mainly explain what webservices are, what is xml..etc... and of course, they did talk about the differenct type of messaging format available. (JAX-RPC..etc..)
4. In the java world - how do you use webservices? Is it the same way that i am familiar with? Like, that we have a front end gui, that it will call the web services, pass it a few param, and get the xml result back, and parse it and display / store.. it? Or that is not the correct way to consume the web services in java world?
5. In .net - as long as i have the .net framework sdk, and a IIS - i am good to go. In java - what do i need in order to deploy a web services?? I already have tomcat / jdk / wsdp / IDE - do i have enough to create a simple ws? if so, can you show me a basic tutorial??
based on some reading, i understand that the ws on the service side, needs an SEI implementing java.rmi.remote, and we need another class implementing this SEI. But I would really want to see more example, or downloads, where i can just download / view the whole thing all at once... I googled "java web service", "jax-rpc example"..etc.. most of the return links are from either java.sun.com, or ibm, or some other vendor's web site, explaining the architecture... I really want to look at the code, to get a better understand, what is the relationship between each of these softwares (tomcat, apache http server, axis...)
Any suggestions??
Thanks,
T

I think I can answer your Q1
Apache is very good at serving simple HTML pages
Tomcat is capable of serving active content
So the two complement each other
Or that's how I understand it.

Java Web Service Book Recommendation

Hello,
my company is converting our old HP database system to Oracle database/server. I am looking for some books that can help me get familiar with Java Web Services. I want to use the latest Java.
If anyone owns/knows a good book to recommend is very appreciated. Also, I would like to get a book regarding security in Java Web Service.
Thank you.

Three words: Amazon.com user reviews. They've never let me down yet.
Note that the online documentation is absolutely not bad at all and the internet is riddled with examples; I managed to figure it all out without the help of a book.
JAX-WS: https://metro.java.net/discover/
JAX-RS: https://jersey.java.net/nonav/documentation/latest/index.html
Of course these are only the reference implementations. Many people choose to use Apache Axis 2 in stead of Metro for example, which has its own (rich) documentation, user base and forums.

Java Web Services Security with 10.1.2.1

I have developed a Java Web Service with J Developer 10.1.2.1 which was deployed onto Oracle 10.1.2.1 application server. Now I have to implement Security for this Web Service (similar to ws-security etc.,), how I can achieve Security with 10.1.2.1?
J Developer 10.1.3.1 seems to have the feature to implement Web Service Security, but a Java Web Service developed using J Developer 10 .1.3.1 with security enabled cannot be deployed onto Oracle 10.1.2.1 application server.
Please help as how I can implement Java Web Service Security with 10.1.2.1?
Email: [email protected]
Thanks for the help in advance.

You can use Oracle Web Services Manager to virtualize the end point and still implement WS-Security.
Thanks

Java web services basic question

Hi all,
I'm new to web services programming, and I'm having trouble getting my head around a few conceptual ideas about web services. I'm in a graduate class right now where our project needs to use web services to create a distributed system. We're using Axis2 and jUDDI for development.
In terms of distributed systems, I am a CORBA programmer, and so when I'm given a problem, my mind immediately goes to how I would implement it in CORBA. Web services seem similar (the WSDL is like an IDL, an jUDDI is like the CORBA naming service, etc) but I'm having difficulty figuring out how to instantiate two (or more) web services that implement the same interface.
From the simple 'hello, world' web services I've done, I have created a java class, compiled it, packaged it into a .aar, and deployed tye aar using Axis2 on Tomcat, my application server (which somehow creates the WSDL file - I'm not exactly sure how that happens either). From there, it's simple to write a client to connect to the web service, which seems to always be running in the application server.
Now, for the system I'm working on, we need to have multiple 'instances' of a service. For example (note this isn't the actual project assignment), say there is a 'GPS_Service' web service with a simple interface with two methods: getLocation(), and setLocation(point p). In my 'application', I want to deploy 15 'instances' of GPS_Service, and set and view their location independently.
Here's where my lack of knowledge hurts. From my point of view, I would need 15 different java classes (i.e. GPS_Service0, GPS_Service1, etc) and 15 different .aar files. Each .aar file would go into the application server, and I would access each service at a different web address.
In CORBA, this is much easier. Classes implement a CORBA interface, and your 'main' method can instantiate as many 'GPS_Service' objects as it wants. This seems to be because CORBA doesn't have an 'application' server where the object is always running.
Does anyone have any suggestions for me, or does anyone have an example of what I'm trying to do?
Thanks,
Eric

I forgot to answer your question.
You have to consume the webservice :
http://gerardnico.com/wiki/ide/eclipse/eclipse_how_to_consume_a_webservice_with_wtp
It will create for you the package
com.siebel.analytics.web.soap.v5
See my example. I think it's enough complete.

Java web services tutorial.

Hi i have seen and tried the Java web services JAX-RPC tutorial.
And i have a question here.
If i want to invoke lets say a web service on a .NET platform, can i still use JAX-RPC to invoke it?
Must the server implement JAX-RPC if i want to use it on the client side?
sorry i still not clear about it.

once you are done creating .war files having WSDL and all, deploy it on Tomcat or any other web container.
create .vb (or which ever language) stub for the JAX-RPC service using WSDL.exe for the .NET enviornment.
In your .NET enviornment, import this stub in your project. In your code, you can define a local varible as a "JavaService" object and assign the instance of your jax-rpc service and use the local variable methods as any other object method calls.

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.

"java Web Service from WSDL" just hands me a SOAPElement, no java mappings

Another beginner question. I've used jdev and built a WSDL starting from a somewhat complex xsd. I've used the wizard "Java Web Service From WSDL" taking defaults. It seems to correctly generate class files for all my xsd types. It produces a fancy looking java-wsdl-mapping.xml But the generated stub service implementation just gets handed a SOAPElement object. Why generate all that mapping stuff and then make me parse the incoming data myself with SOAPElement methods? How am I supposed to make use of the mapping work that the wizard seems to have done for me?
Thanks,
Steve

Dear Tugdual,
Thanks for your intrest in my issue. I narrowed it down to the following type in my xsd
<complexType name="PersonInfoType">
<sequence >
<element name="FamilyName" type="string"/>
<element name="IndividualName" type="string"/>
<element name="SpouseName" type="string"/>
<element name="BirthDate" type="dateTime"/>
</sequence>
</complexType>
This works fine - the "WebSerice From WSDL" wizard "knows" how to generate a class for PersonInfoType (with geters and seters) as well as useful stub implementation:
public class PersonInfoImpl {
public PersonInfoType processPersonInfo(String entityCode) {
return null;
However, if I make my type multiple occuring (to represnt e.g. rows from a db)
<complexType name="PersonInfoType">
<sequence maxOccurs="unbounded" >
<element name="FamilyName" type="string"/>
<element name="IndividualName" type="string"/>
<element name="SpouseName" type="string"/>
<element name="BirthDate" type="dateTime"/>
</sequence>
</complexType>
Now the Web Service generator runs, but just doesn't generate any PersonInfoType class at all. For a stub implementation it genertes the following:
public class PersonInfoImpl {
public SOAPElement processPersonInfo(String entityCode) {
return null;
Now I'm stuck with the container just expecting from me a Soap Object and I have to build all the pieces myself with no java mappings to my xsd at all. Not very useful.
Is there another xml structure I can use to represent data rows that is better supported by the wizard?
Thanks,
Steve

From your post it is not clear what kind of Java web service client (JAX-WS, JAX-RPC, Axis) you are using. The problem being faced is also not clear in the post. Some more elaboration may help others in providing inputs.

Unable to create java web service

morning all
Being new to ejbs I created a simple ejb project comprising one entity bean and one session bean. The session bean exposes two methods one to retrieve individual employee data (return object EmployeeData class which implements java.o.Serializable) and a second retrieving all employee data (return object java.util.Collection).
When I attempt to create a Java Web Service and select the session bean to expose as a web service the method are grayed out, clicking 'Why Not?' displays a message box showing the message
'The following parameter types do not have an XML Schema Mapping and\or serializer specified'
What does this mean and how do I solve it?

Hi,
The java.io.Serializable marker is not consulted when determining whether a Java object can be transmitted in a web service invocation. Instead, each parameter and return value of a web service method must conform to one of the 3 rules below:
1. It is a Java primitive (int, long, byte etc.), Java primitive wrapper (java.lang.Integer etc.), or a java.lang.String.
2. It is a Java bean with a zero-argument constructor, and a pair of "get" and "set" methods for each property to be exposed. Each property must itself conform to one of these 3 rules.
3. It is an array of a type that meets either rule 1 or rule 2.
In the first case, I'd hazard a guess that your EmployeeData class doesn't have the form of a Java bean. Make sure it's got the zero-argument constructor, and that all of the "get" and "set" methods use types which are themselves publishable.
In the second case, java.util.Collection doesn't conform to any of the 3 rules above. However, once you've fixed your EmployeeData class, you can convert the method that returns the Collection into a method that returns a EmployeeData[], which you will be able to publish in your web service.
Hope that helps,
Alan.

Can we deploy a java web service on OC4J within EBS 12.1.3

Hi,
I needed some instructions if this is possible to deploy a java web service on OC4J in EBS 12.1.3.
We don't have SOA gateway integration. The web service is simple SOAP web service.
Is there any document that can be referred for this ?
Thanks

I would try a number of things:
1) Try generating the web service artifacts by using the web service assembler tool that comes with oc4j 10.1.3 dp3. You can use either the command line or ant assembly tasks that are available with the download. There are some fairly detailed examples of using the ant tasks for web service generation at http://www.oracle.com/technology/tech/java/oc4j/1013/howtos/index.html (under the "web services" heading).
2) Try deploying the generated ear file using the admin console. I believe that should work.
3) If for some reason that doesn't work you can try to use the deployment ant tasks (also detailed in the how to examples).
I believe the reason you did not deploy successfully is that even though the core service implementation class, SEI, and JAX-RPC descriptor are portable the artifacts generated in order to deploy the service to a particular application server are unique. JWSDP is tailored to the sun platform.
Hope that helps.

Serialization error while invoking a Java web service

Hi,
I've a requirement where I need to create a Java web service, which returns a collection (a set of records).
The way I've created a web service is by having a Java Class, which internally calls a Pl/sql package returning Ref cursors and a bean Class, which wraps the method of the Java Class, to return the collection. I could create the web service successfully and could invoke the end point. The end point looks like this: http://localhost:8988/MyJavaWebService-New_JWS-context-root/MyWebService_finalSoapHttpPort
The method exposed for the web service in my Java class is of type ArrayList, to fetch the collection element.
After giving the input at the end point, while I say invoke, for the web service, I get the following error:
<env:Envelope
xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ns0="http://mypkg/types/"
xmlns:ns1="http://www.oracle.com/webservices/internal/literal">
<env:Body>
<env:Fault>
<faultcode>env:Server</faultcode>
<faultstring>Internal Server Error (serialization error: no serializer is registered for (class mypkg.EmpBean, null))</faultstring>
</env:Fault>
</env:Body>
</env:Envelope>
I've tried making my exposed method of type Vector as well and re-generated the web service. But still I face the same issue at invocation.
Can anybody help me out and hint me on how I should proceed? I'm not sure if my approach is correct and so please correct me if I'm wrong.
Thanks in Advance,
Gayathri

How to test a Java Web Service locally?

I developed simple java web services.
Now I want to test them locally.
I want to expose my web service through my Web Server(Tomcat).
How can I expose that webservice?
After that I want to access my web service through a Internet Browser.
Is it possible to test that web service locally (localhost)?
My computer is not connected to a network or internet.
My OS is Windows XP Professional.

I just set up TCPMON. Considering it is free and the fact that it has more than just a basic UI, I am quite impressed. I also use SOAPscope, which is another great tool, but I am looking for a free option.
My issue: I set up TCPMON to sniff messages sent over HTTPS through port 8080. But I am getting encrypted messages upon sending the SOAP request as follows:
�b�b�b�bvC�Ym�)f��OvC�Ym�)f��W�O�k�v�W��dQ�$�{� �4��F���vO��XEC

Any clue why?

Problem in fetching values from Java Web Service returning ArrayList

Hi all,
I am calling an External Java web Service from BPEL. That Java Web Service is returning an Arraylist.
I am not able to assign the values returned by the Java web service to local String Variables of BPEL.
Kindly help me...

Hi,
My problem has been resolved..
I have used
bpws:getVariableData('Invoke_1_useSSH_OutputVariable','parameters',concat('/ns7:useSSHResponseElement/ns7:result/ns8:item\[',bpws:getVariableData('count'),']'))
where count is the local int variable which contains the index value of the arraylist i.e. which index element we want to retrieve from arraylist.
Thanks....

hi,
I created a java web service and deployed it on my Application server. When i open the enterprise manager i find my webservice there. I click on test web service and it gives me two options one with a 4443 port and other with a 7777 port. It picks up a 0.0.0.0 hostname though i deplyoed it on to a different machine.
I choose to use the 7777 port and test the web service whrn i click invoke it give me the error
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
and when using the 4443 port it gives me the error as
"SSL Error: unable to find valid certification path to requested target"
please suggest how i can test a simple java webservice.
Thanks
