J2EE web service client using WSDL

Hi,
We are required to develop client program in Java for the
web services developed in SAP XI 2.0.
We will be getting the WSDL files for corresponding web
services.
We have tried doing it with J2EE JAX-RPC...
We studied the sample program of HelloService...
While calling the service from command line..it takes .jar file..
But we have to make use of only WSDL....
Is there any alternative way?? or jax-rpc is the best one???
wat will be the best way to do so??

Hi,
thanx for your reply!
We have written web services in SAP XI 2.0....
we has generated corresponding WSDL..which is little
incomplete..but we can modify and update it according to
requirements...so we have complete WSDL....for corresponding web
services.
My colleagues have developed web dynpro application which
makes use of those services. Now for demostration purpsoe we need
to write java/jsp which will access those services...
can u help???

Hi,
The error message said
the Permission(java.lang.RuntimePermission getClassLoader) has not been granted to USF.
I'd follow the suggestion
The PL/SQL to grant this is dbms_java.grant_permission( 'USF','SYS:java.lang.RuntimePermission', 'getClassLoader', '' )
In case you have not done so, consult the Callout Users Guide @

How to retrieve the multiple rows data on PDF form in a web service method using WSDL DataConnection

How to retrieve the multiple rows data on PDF form in a web service method using WSDL DataConnection.
I have a multiple rows on PDF form. All rows have 4 textfields. I want to submit the multiple rows data to a method defiened in webservice.
Unable to retrieve the data in multiple rows within webservice method.

Hi Paul,
I'm now able to save the retrieved xml in a hidden text field and create dynamic table, and I'm able to fill this table from the XML, but the problem is that I could not find the correct way to loop on the xml, what I'm trying to say, the table will have number of rows with the data of the first row only, so can you tell me the right way to loop on the xml!
this is my code
TextField1.rawValue=xmlData.document.rawValue;
xfa.datasets.data.loadXML(TextField1.rawValue, true, false);
for(var i=0; i<count; i++)
xfa.form.resolveNode("form1.P1.Table1.Row1["+i+"].Num").rawValue = xfa.datasets.data.record.num.value;
xfa.form.resolveNode("form1.P1.Table1.Row1["+i+"].Name").rawValue = xfa.datasets.data.record.name.value;
Table1.Row1.instanceManager.addInstance(true);
Thanks

Issue with creating Web Service Client using Oracle JDeveloper

Hi All,
I am trying to create a Web Service Client using Oracle JDeveloper. I set the Project compiler property to JRE 1.4
When I run the web service client, it throws me bunch of errors saying:
'Error(32,2): annotations are not supported in -source 1.4'
I am wondering why JDeveloper is using annotations even after I set the compiler property to 1.4
I am following this link to create the webservice client:
http://www.oracle.com/technetwork/developer-tools/forms/webservices-forms-11g-094111.html
Any help in this regard would be greatly appreciated.
Thanks,
Scott.

Dear Shay,
Thanks for your prompt response.
You are right. JDeveloper 11g uses JDK 6 style annotations for the clients it creates. But you can change the JRE Version used at compile time by following these steps:
1. In the Applications Navigator, right-click the Project Nanem node and select Project Properties... from the context menu.
2. Select the Compiler node and check the Source Files and Generated Class Files dropdown lists. You may change these versions depending on the version of the JRE you are using with Forms to ensure that the compiled
classes from JDeveloper can be read by the JRE used by Form.
So I selected JDK version 1.4 there.
Sorry that I did not mention that we are using Oracle Forms 10g. That is the reason I selected JDK 1.4
Thank you.
Scott.

Create Web Service System using WSDL URL

Hi,
Please help me create a Web Service System.
Following is the test result when I perform Connection Test after creating a system
Test Connection with Connector
Test Details:
The test consists of the following steps:
1. Retrieve the default alias of the system
2. Check the connection to the backend application using the connector defined in this system object
Results
Retrieval of default alias successful
Connection failed. Make sure that Single Sign-On is configured correctly
Thanks,
Atul

Let me reiterate my problem.
I created the System as following
Creating System's Object:
1) Go to System Administration
2) Go to System Configuration
3) Go to Portal Content on Object Based Navigation Area (Right Side Panel)
Note: For avoiding confusion it is recommended to create a folder in which we are creating System Object.
4) Right Click on Portal Content, select New -> System (from Template)
5) This action will display a new view on right side, now choose Web Service System using WSDL URL radio button from the existing templates. Click Next
6) Give the System Name i.e. System_WS and System Id (which are mandatory fields) incase you want to give any brief notes about the system then give it in Description field. Click Finish.
8) Choose Open the object for editing Click OK.
9) Now to create a Web Service System, we need WSDL URL.
10) There are lots of freely available WSDL files on internet, search for any such WSDL file.
11) In the Properties area of system give the appropriate WSDL URL
12) Choose System alias, from display menu and give alias as System_WS.
This alias name will be the name of Web Service System.
I used the following url
http://soap.amazon.com/schemas2/AmazonWebServices.wsdl
After the system is created,
1) Right click on the created system> open > object
2) Drop down for Display options is changed to Connection Tests from what it shows as object
3) Check the check box for the test name Connection Test for Connectors
4) Result shows that the connection failed. The error message was posted in my first question.
Thanks,
Atul

Web Service Project using WSDL file

Hi All,
I want to create web service project using WSDL file(I already have a wsdl file), which needs axis2 run time to generate correct project structure, I did this in eclipse but now I want to do it through JDeveloper(11.1.2.0.0), so please suggest me any ways on how can I configure axis2 runtime in Jdeveloper, and is it possible do it in Jdevloper?
Thank You,

Have you installed the 64-bit Access driver on your machine? See
Data Source Names and 64-Bit Operating Systems for the differences in odbcad32. Call %SystemRoot%\system32\odbcad32.exe to check the drivers.
How do you host your service? Stand-alone or IIS or embedded to another application? Keep in mind that IIS7 runs it in its application pool which is defaullt 64bit. Thus the bad image exception, when compiling your service as 32bit.
When you need the Access database for your service to store informtation, then I would switch to SQL Server (Express) or XML files depending on your actual needs.
Also check whether your account under which your service is run has the necessary NTFS file permissions on the access file and the folder. This is getting even more complex when it's a remote folder.

Creating web service client with WSDL in NetBeans

NetBeans: 5.5
Java: 1.6
WSDL: http://jira.atlassian.com/rpc/soap/jirasoapservice-v2?wsdl
Using netbeans, I can't seem to successfully generate the stubs for a client based on the WSDL file above.
SoapUI ( www.soapui.org ) has no problems receiving and creating the client stubs using the same WSDL file.
The error I'm getting in the dialog is "Illegal attempt to exit early".
Further details from the output window reads as follows:
-=-
warning: src-resolve: Cannot resolve the name 'impl:ArrayOf_tns2_RemoteEntity' to a(n) 'type definition' component.

And on and on...
What is going on? Why can't I generate my web service client? Any help is greatly appreciated!

There is a bug in the processLauncher for deploytool. The workaround is to edit the processLauncher.xml located under <AS_INSTALL>/lib/processLauncher.xml and add
add xalan.jar and mail.jar to the classpath includes of the s1as-deploytool process:
includes="appserv-assemblytool.jar,activation.jar,appserv-admin.jar,appserv-cmp.jar,appserv-rt.jar,j2ee.jar,jaxrpc-impl.jar,appserv-ext.jar,deployhelp.jar,admin-cli.jar,dom.jar,xercesImpl.jar, xalan.jar, mail.jar"
The web service wizard should now work.

Problem creating web service client using WSM Policies

Hello everyone,
I'm trying to make a simple java client to a Web Service secured using a WSM 11gR1 policy (from Soa Suite 11.1.1.2.0). The policy on the server side is oracle/wss11_x509_token_with_message_protection_service_policy which I attached via the Weblogic Admin Console. To implement the client I'm trying to follow the instructions from this documentation: http://download.oracle.com/docs/cd/E15523_01/web.1111/e13713/owsm_appendix.htm#WSSOV386 section "Policy Configuration Overrides for the Web Service Client" and also I'm using OEPE 11.1.1.3.0 (Eclipse 3.5.0) to develop the client. The only weblogic jar I've added to the build path is the weblogic.jar . Unfortunately, the oracle.wsm.security.util.SecurityConstants.ClientConstants interface (used in the example A-6) is not included in this jar and I have no idea what other libraries should I include in order to follow the example. I tried manualy adding other jars but without success. In fact I found one jar which includes this interface, the wsm-secpol.jar but it does not have the properties described in the documentation, so I guess it's not the right jar, and also I don't think this is the right procedure since there might be another dependent jars. So I would like to know what libraries exactly I should add to the build path (or some other procedure if you noticed I'm doing anything wrong)
Thank you !

Hi
I am having the same problem almost where i wrote a client to comsume a JWS server in https. Where the server is setup to require a certificate to connect to.
My code:
public static void main(String[] args) {
try {
DataBaseSyncServerImpl port = new DataBaseSyncServerImplService().getDataBaseSyncServerImplPort();
int number1 = 20;
int number2 = 10;
System.out.printf("Invoking divide method(%d, %d)\n", number1, number2);
double result = port.divide(number1, number2);
System.out.printf("The result of dividing %d and %d is %f.\n\n", number1, number2, result);
when run this code throw
run:
[java] Invoking divide method(20, 10)
[java] Exception in thread "main" javax.xml.ws.WebServiceException: HTTP transport error: javax.net.ssl.SSLHandshak
eException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCert
PathBuilderException: unable to find valid certification path to requested target
Does any one know how can I solve this problem or how can I make the client be able to use self signed certificates. Any help is greatly apprecited. Thanks

JDeveloper 10.1.2 only understands a subset of all of the complexTypes that can be defined in a WSDL document. For example, if the following appear in the "types" section of the WSDL, any use of those types will cause JDeveloper to generate a reference to UnknownType in a stub or skeleton:
•     Restrictions of simpleTypes
•     complexTypes which define attributes Does that mean that the jdeveloper will not support complex types?Could anybody tell me how to resolve the above said issue? Is there any patch that i can run to resolve the issue?

Can i use the client generated using jdeveloper 11g to import into the oracle forms 10g, i.e., form builder 10g. Currently this is the version we have in our office.

Web Service Client using computer name instead of IP

Hi,
I've built a small EJB web service with a JAVA application deployed via JAVA Web Start for the client.
I testing the application on our LAN and it worked perfectly on one machine. I tested it on another machine and I get an erro along the lines of:
HTTP Transport Error java.net.UnknownHostException: Ian
"ian" being the computer name of the server machine hosting the EJB we service. I presume the program worked on the first machine as it new which computer on the LAN was "ian", whereas the second machine didnt'.
The applications were built in NetBeans and the only place i can see the "ian" address being used is in the client WSDL file:
<service name="VOQAOnline">
    <port binding="tns:VOQAOnlineSEIBinding" name="VOQAOnlineSEIPort">
      <soap:address location="http://ian:8080/VOQAOnline-EJBModule/VOQAOnline"/>
    </port>
</service>Netbeans seems determined to keep this address using the computer name, even if i delete the web service refernce add it again using the server ip address. I've also tried editing the WSDL file in the client JAR post compile, however the error still occurs, so maybe the problem is somewhere else?
The App server I am using is JBoss 4.0.3. Maybe there is a configuration on the server i need to do?
Eventually I plan to deploy the client app over the Internet, so using the computer name is clearly insufficient and it needs to use the IP. It's really annoying how it works on some machines on the network but not others. Any ideas on how to solve this?

You can associate a Virtual Host to the loopback IP address 127.0.0.1 read about Virtual Hosts here: http://tomcat.apache.org/tomcat-6.0-doc/virtual-hosting-howto.html
But with the above configuration alone you can access your app via http://somedomainname.com only on your local machine, no one else on the internet will see it.

Error in creating Web service reference using WSDL

Hi Experts,
I'm using apex 4.1, Oracle 11g
ERROR MESSAGE: The WSDL document was unretrievable because either the URL you supplied was invalid, your environment requires a valid proxy server address for HTTP requests and you have not defined one for this application, or a wallet needs to be configured for this instance of Application Express for HTTPS requests
I know this is a famous issue apex devs faced. I'm having the same problem now. I went through many forums and websites and came to a conclusion that this is something to do with
ACL.
This is wat i'm trying.
1) I have Apex and my web service running on the same server. (We don't use proxy server to connect to W'service)
2) This is the path of the WDSL document i gave - 127.0.0.1/EPRWS/DashboardService.asmx?WSDL
3) I created a default Oracle Wallet by giving no other information other than user name password.
4) i gave the default wallet's user name, password in apex app.
5) The only data that I inserted into ACL table as follows,
BEGIN
DBMS_NETWORK_ACL_ADMIN.CREATE_ACL('power_users.xml',
'ACL that lets power users to connect to everywhere',
'FLOWS_030000', TRUE, 'connect');
DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL('power_users.xml','*');
END;
begin
dbms_network_acl_admin.add_privilege (
acl => 'power_users.xml',
principal => 'FLOWS_030000',
is_grant => TRUE,
privilege => 'connect'
END;
I guess the data inserted into ACL tables as given above to give user privilege is not accurate. Could someone explain me how to properly populate the ACL tables and what exactly needs to be inserted into both ACL tables ? And Should we give anyother information when we create a wallet to fix the able issue ?
Thanks in advance
Kurubaran.

Thanks Role for your reply. As you said i used "APEX_040100". Following script did the magic and now i can call the service. :)
BEGIN
DBMS_NETWORK_ACL_ADMIN.create_acl (
acl => 'power_users.xml',
DESCRIPTION => 'A test of the ACL functionality',
principal => 'APEX_040100',
is_grant => TRUE,
privilege => 'connect',
start_date => SYSTIMESTAMP,
end_date => NULL);
DBMS_NETWORK_ACL_ADMIN.assign_acl (
ACL => 'power_users.xml',
HOST => '*',
LOWER_PORT => NULL,
upper_port => NULL);
DBMS_NETWORK_ACL_ADMIN.add_privilege (
acl => 'power_users.xml',
PRINCIPAL => 'APEX_040100',
is_grant => TRUE,
privilege => 'connect',
position => NULL,
start_date => NULL,
END_DATE => NULL);

Problem when generating web service client using eclipse JavaEE

Hi,
I have created a subservience in SAP .. and the WSDL endpoint is :http://10.130.105.8:8000/sap/bc/srt/wsdl/flv_10002A111AD1/srvc_url/sap/bc/srt/rfc/sap/ztm_ws_get_emp_holidays/520/offici…
But there is problem when I set the service definition. Can you help me, in how to generate the Java classes for SAP web service ?

Hi,
Hello again .
Have you tried your service using soapui ?
You can use your WSDL as input .
In order to eliminate eclipse problem try this service:(I just did)
http://www.oorsprong.org/websamples.countryinfo/CountryInfoService.wso?WSDL
Regards.
package main;
import java.io.FileInputStream;
import java.rmi.RemoteException;
import java.util.Properties;

import org.oorsprong.www.websamples_countryinfo.CountryInfoServiceSoapTypeProxy;
import org.oorsprong.www.websamples_countryinfo.TCountryCodeAndName;
public class Main {
public static void main(String[] args) {
try {
   final Properties properties = new Properties();
   properties.load(new FileInputStream("properties.ini"));
   System.getProperties().putAll(properties);
} catch (final Exception exception) {
   exception.printStackTrace();
new Main();
public Main() {
try {
   final CountryInfoServiceSoapType infoServiceSoapType = new CountryInfoServiceSoapTypeProxy();
   final TCountryCodeAndName[] tCountryCodeAndNames = infoServiceSoapType.listOfCountryNamesByName();
   for (final TCountryCodeAndName tCountryCodeAndName : tCountryCodeAndNames) {
    System.out.println(tCountryCodeAndName.getSName());
} catch (final RemoteException exception) {
   exception.printStackTrace();
