User defined Object transfer in java web service

Hi,
I want to return an object(serialized) from the server to client during a method call.
I tried to return the object as like String object given below.
@WebMethod
public ValueVO getValues() {
ValueVO vo = new ValueVO("arg1", "arg2");
return vo;
But in the client side I am getting an the following errors. The same I am getting for the generic return type Object also.
Compilation Warnings

How to use user-defined packages in JAX-RPC web service

I am trying to use Object of my class located in my package in jax-rpc webservice,the code is
package supercomputer;
import Hello.*;
public class SuperImpl implements SuperIF
public String sendParam(String data)
Temp ob=new Temp();
int i=ob.get1(10000);
return data+"returned by supercomputer";
Temp is located in Hello package,I have jar the Hello package as Hello.jar and has set its classpath in targets.xml of Ant tool.
The code compiles well and service is deployed successfully,but when i try to call the service from the client its gives me following error.
[echo] Running the supercomputer.SuperClient program....
[java] java.rmi.ServerException: Missing port information
[java] at com.sun.xml.rpc.client.StreamingSender._raiseFault(StreamingSender.java:357)

[java] at supercomputer.SuperIF_Stub.sendParam(SuperIF_Stub.java:60)
[java] at supercomputer.SuperClient.main(Unknown Source)
I dont know if it deploys why it gives error on client side.
Please tell how to use user-defined packages and class in jax-rpc service code ,i am not talking about passing user-defined parameters i am just talking about making objects of user defined classes in jax-rpc service.I think there is some problem in classpath.
Please guide me in doing that.
Thanks,
Farrukh

Farrukh,
I don't know if your error is about a missing class from your custom package, ... what track did you followed to say that?
To use your package in the implementation of you web service, you should only follow the rules of making a web application: put your package jar in your \lib directory inside WEB-INF/ or your package classes unjared in classes (also in WEB-INF/).
As I already said, I have doubts that your error should be originated from a missing class from your package, but:
-try to see the logs (errors?) when you deploy your web service that could give a hint about the problem.
-try to see if you can access your endpoint through your browser to see if there is a online status
-display your config/WSDL file, and the steps you did to build your web service.

Pedro Salazar.

Help need in Java Web Service method receiving object values as null

Below is my web method and Package is the object received from dotnet client as a consumer. I have also defined the Package object structure. Now when I receive the data from dotnet I get only identifier value, but I get ownerid and price as null, even both values are sent by Dotnet client. I want to know whether only primitive datatype in java web service works or I need to do some configuration changes in order to have build in Wrapper class datatypes? It would be a great help if somebody explains.
@WebMethod
@WebResult(name = "PackageId")
public long createNewPackage(@WebParam(name = "Package") com.db.radar.wl.data.Package data1,@WebParam(name = "PackageDetail") PackageDetail data2,@WebParam(name = "PackageTrade") PackageTrade data3);
public class Package {
Long ownerid;
Double price;
long identifier;

Using request object in java web service code

Hi,
I am working on a java web service and require the request object in my code.
This is because i want to get the name of the user who is using this web service.
I am getting error in the line
IPortalComponentRequest request = (IPortalComponentRequest) this.getRequest();
Please guide me how to use the request object.
Please also suggest if there is any other way to get the name of the user who is using the web service.

Simple answer: This is not possible due a web service doesn't has such request objects.
If you want to use the user information you have to pass it from the programm logic you are calling the web service. When you have e.g. a JSPDynPage you can read out the user information and supply this information for your web service.

Dispose a user-defined object in Java

Hello,
Suppose I have the following loop :
while ( some_condition) {
UserDefinedClass abc = new UserDefinedClass();
// do some work and exit loop.
Everytime, I enter this loop I instantiate a new object "abc". I am worrying that if I keep doing this, after a while, I will run out
of memory. Is there a way to dispose a user-defined object? Or is this scenario taken care of by Java garbage collection process?
Any advice is much appreciated.
Akino.

Hello,
Thank you for your reply.
I wonder if you could tell me how often Java does its garbage collection?That's pretty unpredictable.
I ran a test and observed that
my program's memory usage kept going up and up.If you gave it it 64M, and the most it ever needs at one time is 10M, it can still ramp up to the full 64M, even if it's doing frequent GC. Running GC does NOT mean that the JVM gives the memory back to the OS. It can do that, and I think it does under some circumstances, but there's no guarantee if, when, or how much it will give back. GC only means that the JVM has reclaimed space that is no longer in use by objects. Whether it holds onto that memory for future use or gives it back to the OS is up to it.

Hi;
I used Fiddler to monitor the process, and it showed the request sent thru web service worked and returned a value, but in my .Net application the return captured as NULL. Could you please look into the code above and the result from Filddler and see if
you can help.
thank you.

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.

Java Web Services wrapper and connection management.

We are currently evaluating the use of the SES Java web-services for a custom front end. I've downloaded the sample code and have read through the documentation but I'm confused on a few points.
We will be OSSO protecting the app, so the flow I think I need to use is (on the OracleSearchService object):
*setSoapURL
*proxyLogin
*setSearchUser
*doOracleSearch
(do whatever with results)
From what I can tell each one of these does a separate call into the actual web service. Does this keep a connection open between these calls and if so how do we need to manage our connections in this case. Is there an explicit close method we should be calling? I see that we can get an OracleSoapHTTPConnection from the undocumented getConnection method on OracleSearchService but I'm unsure if we are supposed to interact with it directly.
In a related vein how should we managing our OracleSearchService objects? Should we save an instance for each user in our httpSession, or just create a new instance on each call?
Any insights appreciated,
Jason

No Problem at all
Nomally the Web Service is big different between Web application. or you can build your Web service structure like web application structure. It depends on the web server:
If the Web Server of hosting company has WEB Service framework, you just need know how to deploy your Web service to Web Service framework and How to deploy to Web Server. In this case, you need deploy it two time, one is for Web Server framework and one is for Web Service framework
If the Web Server of hosting company doesn't has WEB Service framework, you need build your own Web Service framework into a web application, then you just need know how to deploy your web application with Web service into Web Server framework

Java web service with php SOAP client

Hi!
I have a Java web service with a procedure, which connects to a database:
public boolean connectDB(String driver,String host, String user, String password)
try {
Class.forName(driver);
connection =
DriverManager.getConnection
host
, user
, password
return true;
} catch (Exception v_exception) {
System.out.println("connectDB(): " + v_exception);
return false;
If I call it from a PHP client, it doesn't work but doesn't throw any exceptions on the server side.
The way I call it:
$client = new SoapClient
(<path>);
try
$conn=$client->connectDB();
catch (SoapFault $exception)
echo "\nexception: " .$exception;
On the client side, I have an exception, but it's not very detailed:
exception: Object id #2
I had a simple function, too, which returns a string:
public String getTestString()
return "test";
and if I call it from PHP, it's working...
What may be the problem?

Neither the simple "setter" methods work.. :(
The php client side:
$string="aladar";
$client->setSample($string);
$return = $client->getSample();
The server side:
public String sample;
public String getSample() {
return sample;
public void setSample(String a_sample) {
sample = a_sample;
Any ideas?

Calling a java web service from R/3 6.0

hi experts,
can anyone please tell me how to call a java web service from R/3 6.0?
i found some answers to this question but all those were for 6.4 or 6.2 but not for 6.0.
i want to generate a outbound flow from ERP system. so please tell me something about web service in that context.
Thanks in advance,
Sagar.

Hi!!!
I would do this scenario as a synchronous one:
[SAP R/3][ABAP proxy objects] <-> [XI]<->[SOAP Adapter]<--->[external java app]
In your ABAP transaction you will have to execute ABAP proxy method to send a message to XI. If it's not your transaction, you can use user-exit.
BTW, I have an experience with XI 2.0, not with 3.0, so I used a XI 2.0 terminology.

How can i send user defined Object as a argument to the MBean methods in authentication provider to create user?

I developed our own Authentication, Identity Assertion & Authorization providers
for weblogic 8.1 SP1. In the authenticator MBean i have one method which takes
user defined object as a argument and returns a user defined object. i am able
to call all the methods which takes java objects(for example: String, int, ArrayList,
HashMap, Etc...) as a argument and returns also a java object but when i user
any user defined object then it gives exception. if in the argument i used user
defined object then it is not able to call that method telling NoSuchMethodException.
Is there any way to use user defined object as an argument to MBean method?
can anyone please help us as we r in the final stage of the project?
Thanks
Lakshmi

I seem to remember that jmx only supports scalar datatypes. Ask in the

Manual document number in User-Defined Object

Hi Experts,
I have a user-defined object of document type. I am trying to post a document using the General Service. However, I cannot assign manual document number. There is no handwritten property available. Is it possible to assign manual document number in user-defined objects using the DI API?
Thanks.

Hi,
This issue has been resolved. For the benefit of those who will be encountering this error, it was resolved by manually assigning the Handwrtten field to 'Y'. Here is the code fragment:
shipmentHeader.SetProperty("Handwrtten", 'Y')';

The Best Java Web Services Technology for Developing Web Services

Hi,
I am new to Web services world.
I read the java web services page . there are more than 6 technologies.
JAX-WS,
JAX-RPC,
JAXB,
SAAJ,
JAXP,
WSIT,
XWS-Security
I went through several documents on web services.
I could not get a clear idea of which technolgy to use.
Which Java web service technology will be the best to develop web services independant of language, platform.
or is there any 3rd party implemetations available ? for rapid development of web services.
Could anyone help me !.
Thanks in advance.

Which Java web service technology will be the best
to develop web services independant of language,
platform.
Java by nature is a cross-platform language, so if your focus is on the need for portability, the choisce of WS should not be a problem. However, each WS is best suited for paricular uses.
SAAJ, a low-level level API, offers much simplicity, but is not the first choice for programmers, as SOAP (Simple Object Access Protocol)messages need to be constructed piece by piece, making it a quite arduous code to program.
If you are not familiar with XML, your best bet would be to use JAX-RPC (Java API for XML-Remote Procedure Calls), as it hides the underlying detail from the programmer, in terms of SOAP and XML. The shortcoming with RPC-based WS is that it is "restricted to the local programming experience". Another failing is that assumes there is a network path- a reliability concern.
If your program will be contacting other services during downtimes, unlike JAX-RPC, JAXM is quite useful. However, your listing did not mention it, so I wont cover it.
JAXR is a client-side only API that acts as an interface between registries (not referring to JAXP)
I am not famiiar with JAXB, JAXP, WSIT or XWS-Security..
or is there any 3rd party implemetations available ?It depends on what platform you are used to. Assuming you are familiarized with the J2EE platform (now changed to Java EE SDK), the NetBeans IDE (either 5.5, 5.5.1 or the latest editiion) is quite useful. I am using 5.5.1, but have found that it is quite buggy, especially when adding WS operations, a core requirement of a WS. if you will be using to devlop a service for an immediate need, you may find the learning curve to be a bit high, in terms of getting to grips with how to use it. (Download link:
http://www.netbeans.info/downloads/index.php)
The IBM Autonomic IDE (or AIDE), based on the WSDM standard, includes 3 sub-tools, icluding the IBM Manageability Endpoint Builder which, according to their website, allows individuals to build endpoints to allow manageability interface exposure; Manageable Resource Browser and the IBM Manageability Endpoint Simulator. However, I'm not familiar with this IDE. (Download link: http://www.alphaworks.ibm.com/tech/aide/download)
The .NET Framework uses the Visual Studio IDE. For an unbiased comparison of J2EE and the .NET Framework in terms of WS, see http://www.webservicesarchitect.com/content/articles/hanson01.asp.
Apache Axis2, Geronimo and JiBX allows fast development of WS, or so the creators profess.
The PHP environment- you could try NuSPHERE PHPed. According to one website, with it you can develop a web service in under an hour.
I hope this was useful to you.

Handling Java Web Service Exception in ABAP

Hi
I have created a web service in Java using NWDS.
Which has a businessMethod which throws a Exception based on certain business logic.
I have consumed this Web Service Method using .NET Client.
i am able to catch the Exception and get the Exceltion Message.
But when i try to consume the same web service Method in ABAP,
i am not getting the Exception Message .
The Method call works fine.
What am i missing here ?
regards
Rajendra

Hi,
Upon further investigation and comparison of the custom exception object (generated during consumer proxy creation for a CUSTOM web service) with a standard exception object(generated during consumer proxy creation for a STANDARD web service) I found that the sub-elements of the exception structure errorPart are not available in the custom exception object (and one of these sub-elements is the message text).
Call Stack,ExceptionName and MessageText Elements are missing in the errorPart node of Exception
Node. as seen in the ABAP Exception structure generated.
Queries:
1. Are there any standards which need to be followed when coding exceptions in the Java web service for consumption in ABAP such that all sub-elements of the exception object are also created in ABAP during the proxy creation?
2. Can we get the Java code for a standard web service available in SAP Netweaver? Asking the same as the exception object created for the standard web service RoomABAPWS contains the sub-elements. Getting the Java code of the same will be very helpful in resolving the issue.
Regards
Rajendra
