Web Services - Simple Java Classes
Hi folks,
I'm new to using Netweaver and web services in general. I have some existing simple java classes already that I want to convert to a web service. I've decided to try and do a simple test first to make sure I understood how to do this correctly so I followed the steps outlined in this link: (I find I understand this better than the other help files)
<a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/60046fb9-ac5b-2910-08a6-b7b04b463c62">https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/60046fb9-ac5b-2910-08a6-b7b04b463c62</a>
In the end what I got was a class file that has been turned into webservices (the code has @WebService, etc). When I try to do a deployment, everything goes well but I'm not quite sure which link I should use to check out my WSDL or anything. I tried the link like in the article above (but used http://localhost:50000 instead) and wound up getting a 404 error. Is there something I'm doing wrong?
Also, as a quick follow up...since the link shows steps on building EJB's for web services, is it correct to assume that I can use the same steps when building simple java classes? (Create project --> Java Project, create my methods/classes, create new webserive and put slider to Test to check if everything works).
Any help with this will be greatly appreciated I've been trying to figure this out for days already.
Hi Bianca,
Welcome on SDN!
Have you tried to follow the steps exactly as described in the above document? That is, move the slider to "Develop service", then deploy your application, and request http://localhost:50000/HelloWorldBeanService/HelloWorldBean?wsdl - this worked fine for me.
> I find I understand this better than the other help files
Well, which help files you use depends on which version of the NetWeaver AS Java you're using. The link above is applicable to the Java EE 5 preview version; the help files you're probably referencing are the official documentation of the NetWeaver 04 and 04s releases.
Hope it helps!

Parse errors while creating a Web service from Java class!
Can anybody tell me please, is it possible to create a Web Service from java class where the input from user is required ?
I have the following program, which is successfully compiled, but when I'm trying to make a web service in JDeveloper, the following error occurs:
"Validation failed.
The implementation class primePackage.isPrime ofport type MyWebService contains parse errors."
import java.io.*;
import java.util.*;
class isPrime
public static void main (String args[])
Scanner reader = new Scanner(System.in);
int n;
System.out.println ("Enter a number you want to know is it prime or not");
n=reader.nextInt();
if (isPrime(n))
System.out.println ("True");
else
System.out.println ("False");
static boolean isPrime (int n)
int i=2;
while (i<=n-1)
if (n%i==0)
return false;
i++;
return true;
}Hi,
Can anybody tell me please, is it possible to create
a Web Service from java class where the input from
user is required ?Yes, the parameters of your method will be mapped in WSDL.
But i've some considerations about your code.
I suggest you change the name of isPrime do Prime, its a good code convention to put the name of class starting with Upper case. and isn't good the name of class equals to name of method.
I suggest you to change the "static boolean isPrime (int n)" to "public boolean isPrime(int n)" to publish a method as a WebService method it's must be public and not static. After this change try to generate your Web Service.

Web Service From Java class, serialization problem
Hi,
I want to create Web Service from Java class, I made java project, generated web service from it, create web service archive project and deployed it to WAS 6.40.
My class have 2 methods,
public int add(int a, int b);
public MyResponse doSomthing(MyRequest req);
I can succesfully call add method from Web Service Navigator, it works fine but when I call doSomthing methods I get the following error:
<b>
Deserializing fails. Nested message: XML Deserialization Error. Result class [com.mycomp.sap_tech.ws.MyRequest] does not have property [Amount] of type [java.lang.String]. It is required to load XML..
</b>
Any ideas how to resolve it?
P.S. MyRequest class is exposed throw VI, has default constractor and public getters and setters for all properties. It implements Serializable as well. Any guesses?
Thanks in advance,
Victor.Hi Bhavik, thanks for response.
as I already mentioned it implements Serializable, so it is not the problem.
Thanks Avi but it didn't helps iether

Create web service using java class
Hi,
I created the web service using java class then i deployed this web service in to the weblogic admin server.when i tested this process it is working fine.
when I tested The generated WSDL to this process in browser(IE). it is not working.
I need to to invoke this webservice from another BPEL but this WSDL is not working.Hi,
when i created the webservice in jdeveloper by default it is connected to integrated weblogic server and generates this wsdl.
http://localhost:7101/helloApplication-javaexcel-context-root/MyWebService1Soap12HttpPort?WSDL
then I deployed this webservice in to the Adminserver.it gives the following URL.
http://192.168.56.1:7001/extracExcelToCSV-extractExcelToCSV-context-root/ExtractExcelToCSVSoap12HttpPort?wsdl
This URL is not working but when i tested this process it is working fine.
It is giving below error when i try to invoke from jdeveloper
Error while reading wsdl file

Error while deploying web service from Java class
Hi,
I have a simple java class which I want to deploy as web service with some methods in the Java class as web service operations.
How to do this in Jdev 11g?
Is there any good detailed tutorial on this?
I just created an web service from the class and went for deployment in Weblogic.
This resulted in Illegal Annotation Exception as shown below.
Please help!!

Create web service from java class in Jdeveloper 11g
I have very simple java class which I want to expose as a web service. I am using the Jdeveloper's in-built wizard to "Creat Web Service" from a java class. While doing so when I am selecting a method to be exposed as a web service, I get a error pop-up which says "Failed to load system class."
I am not able to understand the reson for this error. I tried to do this with a very simple java code too but still no luck!!
Here is the code:
public class DownloadFileFromECMWrapper {
public DownloadFileFromECMWrapper() {}
public static void main(String args[]){
DownloadFileFromECMWrapper obj = new DownloadFileFromECMWrapper();
obj.callDownloadFileFromECM("C:\\shivam\\MyFile.txt");
public String callDownloadFileFromECM(String filePath){
System.out.println(filePath);
return filePath;
Can someone please help me on this.

Creating Web Service from Java Class-How to eliminate nillable="true"
Does anyone know how to eliminate the attribute, nillable="true", from the element tags which describe the parameters in the WSDL created when creating a web service from a Java Class? It does this only for the string types. Is there something I need to set when creating the web service or before creating the web service? Or the only way is to modify this WSDL then recreate the web service from the WSDL.
example part of wsdl:
this is in the <types> tag:
<complexType name="getData">
<sequence>
<element name="schema" type="string" nillable="true"/>
<element name="table_or_view_name" type="string" nillable="true"/>
</sequence>
</complexType>
<complexType name="getDataResponse">
<sequence>
<element name="result" type="string" nillable="true"/>
</sequence>
</complexType>I did do this and I got the following error when deploying to the Stand-alone OC4j:
Operation failed with error:
Error compiling

Impl class Method: getData declares exceptions not declared by the interface (java.lang.Exception)
I am quite sure what it is saying. It generated the code for the Interface: dbdatapackage.DVDataWS. Impl class. Why would it not do it right? What expection is it complaining about? java.lang.Exception? -

DanieleYou should try to post it there:

But if I look at the error, it looks like some files are Read-Only. Maybe you should check if they are or if you have the appropriate rights on the folder.

Hello,
I have list of java classes. I have one java class which calls only the required functions from the list of java classes. When I try to create a VI on that java class I see all the functions needed but all of them are grayed.
Can anybody please help?
Best regards,
DharmiHas anyone else solved this problem? We too are experiencing the same problem.
We are trying to build a .JWS file from within an ANT build script. The build script compiles the site into a single EAR file that should contain a deployable and usable JWS component, however it obviously does not.
If anyone has a solution, please let us know. We're facing a code freeze on this project by this Friday and really need some help. -
Securing Web Services based on simple Java Classes
Hi @all!
We`ve got the following problem.
There`s a .NET client calling our Web services deployed on Bea Weblogic 8.1 (without
SP).
The Web Services are generated by the ANT task servicegen. They are based on simple
Java classes containing the service methods as public members.
Is there a possibility to secure these methods without using the console menu
item "Define Security Policy" ?
We can`t use this menu because it has got a javascript bug with methods returning
an array.
Thanks in advance for help.
MichaelHi Michael,
Could you use transport level security, SSL [1]?
I'm not sure what limitation you are experiencing with the console? Is
there a traceback? Have you contacted customer support on this issue?
Thanks,
Bruce

String namespace = "http://tempuri.org/";
name = request.getParameter("txtName");
try
System.out.println("In Internet Service");
ServiceFactory factory = ServiceFactory.newInstance();
Service serv = factory.createService(new URL(url),new QName(namespace,"TempConvert"));
System.out.println("Got Service......");
Call obj = (Call)serv.createCall();
System.out.println("Got Call......");
obj.setProperty(Call.ENCODINGSTYLE_URI_PROPERTY,"");
obj.setProperty(Call.OPERATION_STYLE_PROPERTY,"wrapped");
obj.setTargetEndpointAddress(url);
obj.setPortTypeName(new QName(namespace,"TempConvertSoap"));
obj.setOperationName(new QName(namespace,"FahrenheitToCelsius"));
obj.addParameter("param1",XMLType.XSD_STRING,String.class,ParameterMode.IN);
obj.setReturnType(XMLType.XSD_STRING);
System.out.println("Parameters Set.....");
Object[] params = new Object[]{name};

Re: Using simple java class in an .war file.
Hi All,
I have a simple question,
Can I access an simple java class from a jsp file that I have written by putting it in the "classes" folder?? What entry should go in the web.xml file?
Here is my directory structure:
sample.war
|
----test.jsp <file>
|
----WEB-INF <folder>
| |
| ----classes<folder>
| | |
| | ----simpleJavaClass.class<file>
| |
| ----lib<folder>
| |
| ----web.xml
I want to access the simpleJavaClass.class from the jsp test.jsp.
Please suggest.
Thanks and regards
AyusmanIt is possible to access the class in u r classes folder from u r jsp file.
For example
<%@ page import="com.test.service.PricingSolution,
com.test.core.PhoneNumber
%>
<% PricingSolution solution = (PricingSolution)session.getAttribute("solution"); %>
This is a simple scriplet example. You do the same using jstl tags also.

How to consume the Abap web service in Java web-dynpro
Hi Everyone,
I want to consume ABAP web service in java web dynpro.
so when i tried to create model in java web-dynpro, it gave me an error message saying "Invalid WSDL or WSDL not found".
i think this error message is because, to access the WSDL of abap web-service, we need username and password, but the dialog box in java web-dynpro is not programmed to take username and password from us and send it to the server to get the WSDL.
i came to this conclusion because i was able to successfully test my abap web-service in java portal. the java portal asked me the username and password to open the WSDL.
So, please help me to consume the abap web service in java web-dynpro.
Thanks in advance
Regards
VikasHi Vikas ,
while creating a model in web-dynpro try to use the "import web service model" option and if you are using local server choose the local server option so that you can get the available web services which are in server, select one among them and continue you process.I think this is the some what easy way .
If you want use the URL for wsdl better to once test the available service in server and copy that WSDL URL and paste over WSDL textbox.
I think this is pretty help ful to you
Best Regards
