Java instance client Web Service
Hi All
I am a beginner in Java.
I am working on a web service project client/server to which i have created a webservice server in VB.NET and have parsed the WSDL through the Apache server in Eclipse which generates the JAVA code but the project in Eclipse requires that i call an instance of this Web Service, to which i must pass the parameters.
Please could you HELP
Hi All
I am a beginner in Java.
I am working on a web service project.
Which is to be client/server.
The client sends a request to the server and the server responds.
I have created a server based Web Service in VS.NET which is called LoanCalcService and the files that are present are LoanInfo.asmx and Service.vb.
When i run the server in VS.NET it creates a Web Service document called a WSDL.
I have parsed the WSDL document through Apache Server in Eclipse platform using the Web Service Client.
But i understand that i must write about 4 or 5 lines of JAVA code to Call an Instance of the WSDL document to be able to run this in Eclipse to create the Loan Calculator that i have created in VS.NET. I am enquiring to see if anyone can point me in the right direction.
PS. Sry about the quick entry earlier

Problem in writing a client web service from WSDL document
Hi,
I wrote a web service using .Net and a WSDL document. I tried after that to generate a client web service using Jdeveloper. but, the methode generated by Jdeveloper (in the stub) does not represente the original methode.
<?xml version = '1.0' encoding = 'windows-1252'?>
<!--Generated by the Oracle9i JDeveloper Web Services WSDL Generator-->

Here The methode Validate consume two parameters : string and long
the generated stub look like :
public Vector Validate(Element requestElem) throws Exception
There is some one who have a solution ?
---------------------------------------My guess is that it is because .NET defaults to generating a document style interface whereas JDeveloper defaults to generating an RPC style interface. The end result is that JDeveloper wraps the document interface in something that looks document like - thus your client. To see how to handle this right now, check out this sample - you have to parse the XML:
http://otn.oracle.com/tech/webservices/htdocs/series/net/content.html
In the preview of JDeveloper 9.0.3 which is due quite soon - next few weeks roughly (crossing my fingers) - JDeveloper will wrap .NET document based Web services in a much more elegant wrapper - giving you exactly what you are looking for - a method called Validate rather than a vector of Elements.
What I don't understand in your sample, however, is that you have WSDL generated from JDeveloper versus WSDL generated from .NET. Did you also do an implementation of the validate method in Java too?

What the mechanism of the Java Proxy for Web Services in WLS 8.1
Hi, all;
I try to find out how the java proxy of web service in weblogic server 8.1
works. Suppose I use the java Proxy of a WebSerice in a client application whatever
whithin or outside the application of the web service, does the proxy actually:
1. translate my java arguments objects in XML to create SOAP msg,
2. then send the msg across the network, and web service also response SOAP msg,
3. then proxy translate it into return value of the method call ?
If that is true , the Java Proxy seems very inefficient, right?
Can any body tell me how the proxy works ?
regards,
shannonHi Shannon,
The type of proxy I'm familiar with is at the http connection level and
associated with the networking properties in the JDK, See:
http://java.sun.com/j2se/1.4.2/docs/guide/net/properties.html
Your question may be related to JWS proxies, See:
http://edocs.bea.com/workshop/docs81/doc/en/workshop/guide/howdoi/howUseTheJavaProxyForAWebService.html
You may want to ask this question in the workshop newsgroup.
Hope this helps,

Returning java bean from web service
hello i just want to know if it is still platform independent if i make an array of java bean object as a return value from a webservice?
if the return value of a webservice is a java bean, is it required for the client to have a copy of the java bean class? what will happen if the client of the java webservice is in PHP or other language besides java? will it still be compatible?
thanks in advance guys..Yes, you should be able to return a Java bean from a Web service. What will happen is your web service framework, such as JAX-WS (http://jax-ws.dev.java.net) will generate WSDL and Schema that describes the operation and its use of Java bean. Then the client web service framework used will take the WSDL and Schema description and generate something that can marshal/unmarshal the contents of the bean.

Java implementation of web service concept
I am so confused. What exactly is the Java implementation of web service concept? SOAP, J2EE, JSP+Servlets+beans or what?
For an excellent description of webservices in Java read the following article
http://www.theserverside.com/resources/article.jsp?l=WebServices-Dev-Guide
It should clear most of your doubts.
Web services means a client server program which exhanges data in XML over HTTP.
Soap is one way of implementing web services. A java soap implementation is freely available at
http://xml.apache.org/soap/index.html
Also, you can read about ebXML (which is another model for making web services).
http://www.xml.org/feature_articles/2000_1107_miller.shtml
http://java.sun.com/features/2001/09/ebxmlrev.html
hope this helps.

XI 3.0 and external Java client/web service
Hello,
I'm desperately tryin' to get an external system to work together with XI 3.0.
The setup is quite simple:
The external system is nothing but a simple Java program sending SOAP-based requests to a webservice. It is based on AXIS and is running satisfyingly when connecting directly to an appropriate Tomcat/AXIS-based web service, see the following communication.
-- local request

I made sure the business service in the integration directory is named SOAPRequest and is using SOAP as the communication channel. As the adapter engine I chose the integration server, since it is the only option, although the SOAP adapter framework is installed (according to the SLD) and deactivated any options like header and attachment.
Upon facing the above response I also tried any kind of derivative with inserting the described tag/attribute/element versionMajor, but to no avail.
My questions are:
What do I have to do additionally to get the whole thing running, i.e. configure my external systems in the SLD, providing proxy settings?
Do I have to create web services within the Web AS (which provide some kind of facade to the XI engine using the proxy generation) and connect to these instead of directly addressing the integration engine (I'm using the URL http://<host>:<port>/sap/xi/engine?type=entry, but I also tried http://<host>:<port>/XISOAPAdapter/MessageServlet?channel=:SOAPRequest:SOAPIn, this led to a 404 not found error)?
What settings do I have to provide to see the messages the client is sending, when looking into the runtime workbench it seems as if there are no messages at all - at least from my client?
Hopefully somebody might help me out or least provide some information to get me going.
Thanks in advance.
Best regards,
T.HrastnikHello Oliver,
all information I gathered so far derives from the online help for XI 3.0, to be found under http://help.sap.com/saphelp_nw04/helpdata/en/14/80243b4a66ae0ce10000000a11402f/frameset.htm. There You'll find - in the last quarter of the navigation bar on the left side - sections describing the adapter engine alonside the SOAP adapter.
Additionally I went through almost all postings in this forum.
This alonside the mandatory trial-and-error approach (I did a lot of it up to date) led me to my current status, i.e. so far I haven't found any kind of (simple) tutorial or demo saying "If You want to establish a web service based connection via SOAP between external applications and XI first do this, then that ...", sadly enough :-(.
Hope that helps, any questions are always welcome, I'll try my best to answer them ;-).
Best regards,

JAVA as the Client/Web Service consume XML
Working on a project at present and require to use JAVA as the client to consume XML from the Server to which i have coded in VB.NET. I have never used JAVA before and i am asking if anyone can point me in the right direction for this or give me an example of Client code in JAVA that consumes XML from the Server VB.net.
This is cross platform web service that i am working on which must include the following Client/Server one in say for instance JAVA client and VB.NET server which must consume the same text for instance XML, and then display the XML.
Thank You Beforehand
I am a Beginner. But i am willing to learn. There will be a chocolate bar in it for anyone who can point me in the correct direction. Got 3 days to complete, HELPAny particular flavor of XML? (e.g., SOAP)

Java Client Web Service In Platform Eclipse
Hi All
I have created a server Web Service called LoanCalcService in VS.NET 2005, the folder contains LoanInfo.asmx that when run creates the Web Service, WSDL. Which works good.
Now i need to send a request to the Web Service server and get a response from the LoanCalcService that it provides. To do this i must create a client in another language. I am doing this in JAVA in the Eclipse platform.
I have tested the WSDL with the web service explorer that comes with eclipse and the program works good. But when i run the Java code in Eclipse i get this
Error
HTTP Status 404 - /WebServiceProject/WEB-INF/classes/localhost/LoanCalcService/LoanInfo_asmx/LoanInfoLocator.java

Can anyone tell me please what i am missing please.

Calling ABAP BAPIs from a JAVA client - Web Services vs. JCo
Hi All,
When calling BAPIs from a JAVA client, what are the pros/cons for making the call employing JCo vs web service technologies. I understand that using SOAP would play better into the SOA theme and that there are nice tools to generate a WSDL document from a BAPI. Aside from the obvious, are there any performance considerations and/or other major pros/cons to each
Thanks,
MarkHi Mark,
Have you got any information on this. If you have any information on this pls forward to me at <b>[email protected]</b> I am also having this confusion. My question is a bit deviating from your point. If we use XI when developing WDJs with WS, will it help in improving performance and maintenance.will it give any advantage if I use XI with BAPIs to connecto backend from WDJ apps. I got this confusion, becasue of a requirement to develop WDJ apps that will be accessed by 50,000 users. Somebody told client that use of XI willimprove performance.
Any help is greatful

even i have iterated from getPorts() method and used to invoke the service.But handler was not calling when i invoke.
Please guide me here how i specify correct portname which can call Handler class also.

Web service handler could not registered/called in client web service
Hi Expert,
I have two web service ServiceA & ServiceB and both implemented in weblogic.
The ServiceA is SSL enable and protocol is https which is not published by me.
The ServieB is my web service(wls8.1) and act as client for ServiceA.
My problem is when i hit my service, its not able set the handler when it call ServiceA but it is invoking the service and giving application exception like authentication error.

Java app with web service and servlets
Hi. I intend to make a java application which exposes some methods as a web service and as jsp/servlets. It's core functionality is not really web centric, but its more a java app with a web tier. I am not sure about how the architecture of such a system would look like using the java platform. I currently see three options:
1. Run everything in a servlet container like tomcat. I hesitate to do this because i would be putting a lot of functionality which isn't about the web into a servlet container. Also, I have a lot of application scope data that is maintained and shared by all servlets/web services. However, it would be really easy just to put everything into tomcat and use ServletContext to maintain some global objects.
2. Use a Java EE to seperate application/business logic and data access into session beans and entity beans. I hesitate to this because it seem a bit overkill because the system isn't very big or complex right now. It also means that I would have to learn to use EJB's instead of just using some POJOs.
3. Run the web tier in a servlet container and the main app in a separate JVM, and then connect the tier by sending serialized objects over TCP sockets. I don't like writing network code but at least there is some separation of the tiers.
What would you do? Maybe I have overlooked a much better solution to the problem?
Let me just say that the system is the product of a student project spanning one semester, so it's important to choose the RIGHT solution (architectural-wise) instead of the something quick and dirty that is hard to defend.jschell wrote:

Let me just say that the system is the product of a student project spanning one semester, so it's important to choose the RIGHT solution (architectural-wise) That pretty much makes it impossible then.
1. A "Right" solution is generally only proven by time.
2. It requires a great deal of knowledge about the business domain.Yeah, you are right. Let be try to rephrase it. What solution (pattern) would be considered the most common or appropriate when you have a Java App and want to expose a few methods as a website and web service?
I hesitate to do this because i would be putting a lot of functionality which isn't about the web into a servlet container. Also, I have a lot of application scope data that is maintained and shared by all servlets/web servicesHuh? Do you already have an exposed web service? If you already have a server which other clients communicate then where does this functionality that you don't want to be tomcat running now? Or where do you think that you want to run it? And if you are or do run it somewhere else then tomcat could access it the same way any other client accesses that server.Sorry, that sentence was written badly. I don't have anything right now. What I meant to write was that I will have a lot of application scope data, objects that are kept in memory as long as the server is running, shared by multiple servlet instances.
