JSP calls web service

Hi,
I have a problem calling my web services from my JSP. In the JSP (SimpleJSP) I have:
<% page import = "ServiceOneClient" %>
Webservice reply:
<% ServiceOneClient soc = new ServiceOneClient(); %>
<% =soc.requestService(); %>
Whenever I call my JSP I get the following error message:
Error 500: C:\WSDK\WebSphere\installedApps\wsdk.ear\ServiceOne.war\SimpleJSP.jsp(41,0) JSPG0059E: Unable to compile class for JSP JSPG0143E: An error occured between lines: 1 and 34 in the jsp file: C:/WSDK/WebSphere/installedApps/wsdk.ear/ServiceOne.war/SimpleJSP.jsp
JSPG0144E: Generated servlet error:
C:\WSDK\WebSphere\temp\localhost\Default_Server\WSDKdemos\ServiceOne.war\_SimpleJSP_jsp_16.java:77: Missing term. out.print(_jspx_html_data[0]);
^
1 error
I would be very happy if someone could tell me the solution.
Many thanks
Simone

Luke,
Thanks very much again and sorry to bother again. :-(
The class is now in the right path and I get an error message about static referencing.
Error 500: C:\WSDK\WebSphere\installedApps\wsdk.ear\ServiceOne.war\SimpleJSP.jsp(41,0) JSPG0059E: Unable to compile class for JSP JSPG0142E: An error occurred at line: 34 in the jsp file: C:/WSDK/WebSphere/installedApps/wsdk.ear/ServiceOne.war/SimpleJSP.jsp

out.print(ServiceOneClient.requestService() );
^
1 error
Do you know what I have to change in the Java code?
Many thanks
Simone

VO object error while calling Web Service.

Hi,
I created one page with 5 text field and one choice list with three buttons.
Functionality is :
1. As page loads I am calling Web Service to set the values in fields.
2. When user enters new values or changed the old values and click on "Save" button, again web service is called to store that values.
Problem is when changing message choice value. For message choice I created one VO for lookup_code and meaning.
When I click on "Save" Button it showing me error
Attribute set for LookupCode in view object EncryptionModeVO1 failed

Calling web service.

Hello,
I have designed a form in Livecycle designer in which I am calling web service of coldfusion using javascript, passing a xml file as parameter, so here is the code but not working. But I want to ask that is this the currect way of calling web service-
var cURL = "http://ad/web_service.cfc?wsdl";
SOAP.wireDump = false;
var service = SOAP.connect(cURL);
var result = service.addXml( sample.xml );
app.alert(result );
Is this the currect way to call a service by passing xml file as parameter?
Thanks,
Debadas Baral.

Hello,
Could you please be more specific about 'it stops responding'?
Are you sure that your stub is sending the request to the server? Do you have any stack trace? It may be a simple connection issue.
It is hard to answer without any more information. The behavior should be the same using your JSP or your swing application. Have you try to debug the application using Jdeveloper to see in which step the call fails ?
Also if you are running the JSP from JDevelpoper be sure you have the correct proxy settings.

Call web service using code.

we want to call a web service from ADF JSP form.
We used web service data control. But deployment failed.
we applied Patch 5878326 to JDeveloper 10.1.3.3.0 and OAS.
But problem is not solved.
So we need a new way to call web services.
is there any other way to call web services from Jdev.
any code sample will be appreciated.
Thanks.

Workaround for the Connection Failure
In JDeveloper, locate the .deploy file in the Resources folder of your web application project.
Double-click the file to open the WAR Deployment Profile Properties dialog.
Expand File Groups - WEB-INF/classes - Contributors.
In the Contributors panel, click Add and use the Browse dialog to locate the .adf folder in the root for your application (for example, /jdev/mywork//.adf path.)
Select the .adf folder and add it as a contributor to the deployment profile.
Note that the .adf folder does not become part of the deployable archive. This merely ensures that the contents of the META-INF get placed in an appropriate location in the archive that will permit the web container to find it when the application loads.
The failure to get the connection to Webservice is beacuse the "connections.xml" is not available in the deployed archive.
This has been release note'd as in
http://www.oracle.com/technology/products/jdev/htdocs/10.1.3.0.3/10.1.3_addendum.html under "Deployment issues"

Calling web services

Hi,
How can I call web services from Oracle BI?
My web service has a method (GetEventList) which take some parameters and returns a list.
Can I call this web service method from a dashboard and then show it in there?
Thanks&Regards

Hi,
it`s a pity, that OBIEE does not offer a solution to directly send requests to external webservices and show their results within an answer. Before i tried OBI 11g, i hoped that there would be some improvements regarding that functionality in contrast to OBI 10g.
Workarounds:
1.) In Oracle BI Publisher you can directly call a webservice and get back its results within a report. You could then put that report onto a dashboard. (I do not know whether this is already possible in Oracle BI Publisher 10g
2.) OBI 11g Action Framework. You could put a link onto your dashboard, which calls a webservice. After the webservice sent a response, an information dialog is shown, which can be used to present some general info regarding the webservices' return values.
3.) Create an ASP.NET/JSP-File which calls your Webservice and presents its results in HTML. You could then embed this ASP/JSP-File via an IFrame into your dashboard.
4.) PL/SQL-Wrapper as mentioned before
Conclusion: Oracle should improve this functionality by allowing people to directly call Webservices from Answers.

Calling web service request from PL/SQL

I am trying to create Apex page with stock quote ticker - like what Yahoo has on their page. I have the right web service and have put together a page which works when you submit (created by the wizard). Instead of clicking submit to refresh the page I want to use Ajax to do this but for this purpose I need to know how to call web service from PL/SQL so I can do this in my on demand process. Any ideas?

George,
The documented way to call a web service using PL/SQL is to use UTL_DBWS package.
Here are a couple of links that may be useful:
http://www.oracle-base.com/articles/10g/utl_dbws10g.php
http://www.oracle.com/technology/sample_code/tech/java/jsp/callout_users_guide.htm
There is also an APEX package wwv_flow_web_services, but I couldn't find any documentation on it.

Calling web service from oracle forms 10g

Problem Description:
I'm following the steps as per the doc:
http://www.oracle.com/technology/products/forms/htdocs/10gr2/howto/webservicefromforms/ws_10_1_3_from_forms.html
to create a java stub to call external web service and then use java importer in oracle forms to call this web service from oracle forms.
WSDL for external web service used is http://gend:83/DesignService.svc?wsdl
The service was developed by us.
Calling the web service using JDeveloper works fine but when I complie in Oracle Forms it returns wrong number of types of arguments in call SENDHELLO.
The code from oracle form to call web service is as below:
DECLARE
jo ora_java.jobject;
xo ora_java.jobject;
rv varchar2(2000);
ex ora_java.jobject;
str varchar2(100);
BEGIN
jo := GendServiceClient.new;
rv := GendServiceClient.sendHello('Nora');
EXCEPTION
WHEN ORA_JAVA.JAVA_ERROR then
message('Unable to call out to Java, ' ||ORA_JAVA.LAST_ERROR);
WHEN ORA_JAVA.EXCEPTION_THROWN then
ex := ORA_JAVA.LAST_EXCEPTION;
message(Exception_.toString(ex));
END;
Any help/ideas on this is greatly appreciated. Thanks.

My primary skill is PL/SQL but the only information I found on Oracle's site to call a web service from a 10g Form was creating a jar file and importing the java class. Since I don't want to ask our corporate IT to make changes on the UNIX box for the jar files I went a different route.
I use UTL_HTTP.BEGIN_REQUEST to call a URL then load I load the data to a table as a CLOB since we have more than 4000 characters. Now I need to parse the XML and load it into a form. I have never done this so if there is a helpful site please let me know. I have looked at several sites but none do what I want.
Thanks

Calling web service from oracle forms fails with ORA_JAVA.JAVA_ERROR

Problem Description:
I'm following the steps as per the doc:

to create a java stub to call external web service and then use java importer in oracle forms to call this web service from oracle forms.
WSDL for external web service used is http://www.webservicex.net/CurrencyConverter.asmx?wsdl
Calling the web service using JDeveloper works fine but from Oracle Forms returns ORA_JAVA.JAVA_ERROR; Unable to call out to Java, Invalid object type for argument 1
The code from oracle form to call web service is as below:

Yes, it is the message line - so basically this call fails => rv:= CurrencyConvertorStub.ConversionRate(jo,'CAD','USD'); and control goes in the exception block
WHEN ORA_JAVA.JAVA_ERROR then
message('Unable to call out to Java, ' ||ORA_JAVA.LAST_ERROR);
Below is the code from java stub that was generated using JDeveloper by using web services stub/skeleton and associating the WSDL

requestData.add(new Object[] {"FromCurrency", FromCurrency});
requestData.add(new Object[] {"ToCurrency", ToCurrency});
requestBodyEntries.addElement(toElement(wrappingName, targetNamespace, requestData));
requestBody.setBodyEntries(requestBodyEntries);
requestEnv.setBody(requestBody);
Message msg = new Message();
msg.setSOAPTransport(m_httpConnection);

How to make a PDF form call Web service and return a static pdf for user to print?

Hi all,
Can anyone help me regarding the feasibility of using PDF forms for my following case?
I would like to create a Dynamic pdf form. User only have the Acrobat reader. they can enter some information. Then have a submit button. when user click the submit button, it can call the web service with data. then Web service returns a Static PDF document based on data and the user can print it out. (and maybe save as separate pdf file)
1. Is that possible to implement? Because I know PDF can call web service, but dont know how it handle when the webservice returns another static PDF document. could it able to handle the responds and open up in another acrobat reader?
2. As I understand I need to have Live Cycle Designer to create a pdf and make it Reader Enabled. So user can user reader to call webservice? am I correct?
3. What minimum reader that user need to have? PDF reader 7 or above?
4. I have a webservice serve the same purpose for web. But if I want the same web services can serve both web and PDF form. So, whatever client (PDF or Web)make the web service call, server returns the PDF document to client. Is that possible ? Do I need to make any changes on web service?
5. Do I need to get any other Adobe server product? (other than Live Cycle Designer )
Thanks a lot

We have done a similar approach in the past and yes, it can be doable.
1. Is that possible to implement? Because I know PDF can call web service, but dont know how it handle when the webservice returns another static PDF document. could it able to handle the responds and open up in another acrobat reader?
Srini: We have developed a Servlet to talk to Webservice. Based on the Webservice response, the Servlet, prepares the Byte stream and sends it to Webbrowser to display as a PDF. The PDF data was submitted to Servlet in XML format.
But if you do not want to use the above approach, then you have to use the Workbench Process.
Submit the PDF data to a Workbench process and the inside process, execute Webservice Service with the data. Once the response is received, prepare the data XML and render a PDF with it.
To do this, you need LiveCycle Server and Reader Extensions server component.
2. As I understand I need to have Live Cycle Designer to create a pdf and make it Reader Enabled. So user can user reader to call webservice? am I correct?
Srini: If you want to use the Servlet, you can Reader extend the PDF with Acrobat.. But if you want to submit the data directly to Webservice, then you need Reader Extensions server component.
3. What minimum reader that user need to have? PDF reader 7 or above?
Srini: Not sure but Reader 8 and above should work.
4. I have a webservice serve the same purpose for web. But if I want the same web services can serve both web and PDF form. So, whatever client (PDF or Web)make the web service call, server returns the PDF document to client. Is that possible ? Do I need to make any changes on web service?
Srini: If you use the Servlet approach, then you can re-use the same webservice. But if you want to submit directly to the same webservice, you may need to change it to suit your data XML.
5. Do I need to get any other Adobe server product? (other than Live Cycle Designer )
Srini: If you use the Servlet approach, you do not need any server component but other approach, you need Livecycle Server and Reader Extensions server component.
Thanks
Srini

How to call Web Services (with javascript) in a view load event ?

Hello to the expert community,
I'm looking for a piece of javascript code allowing to call Web Services in a view load event ?
Any ideas will be really appreciated.
Regards.
Have a nice week.

Thank you for your answer, dongmei.
It seems that the MethodResultTableDataProvider does not return the response of the web service as a value field if the WSDL contains only one result element.
E.g. from WSDL of the USWeather Web Service which returns theGetWeatherReportResult string:
<?xml version="1.0" encoding="utf-8"?>
<wsdl:definitions xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:s="http://www.w3.org/2001/XMLSchema" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:tns="http://www.webserviceX.NET" xmlns:tm="http://microsoft.com/wsdl/mime/textMatching/" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" targetNamespace="http://www.webserviceX.NET" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/">
<wsdl:types>
 <s:schema elementFormDefault="qualified" targetNamespace="http://www.webserviceX.NET">
 <s:element name="GetWeatherReport">
 <s:complexType>
 <s:sequence>
 <s:element minOccurs="0" maxOccurs="1" name="ZipCode" type="s:string" />
 </s:sequence>
 </s:complexType>
 </s:element>
 <s:element name="GetWeatherReportResponse">
 <s:complexType>
 <s:sequence>
 <s:element minOccurs="0" maxOccurs="1" name="GetWeatherReportResult" type="s:string" />
 </s:sequence>
 </s:complexType>
 </s:element>
 <s:element name="string" nillable="true" type="s:string" />
 </s:schema>If I drag the web service method on the page and I should be able to select the response value in the Bind to Data dialog box. But there is no value field. Value fields only occur if the web service returns more than one value.
The question is how can I get the response GetWeatherReportResult from the service.

Is there a way to call web service from 2 servers??

Hi,
I need to know if its possible to call web service from 2 different servers without having load balancer??? I mean, if one of the server has heavy work on, then it should call web service from the other server.
Thanks in advance.
Best Regards.

Hi,
WebLogic Cluster has this feature ( Load Balancing & Failover ). If you will deploy your WebService to a WebLogic Cluster and then If you will put a Proxy in front of it like (Apache)...Then it is Possible.
<h3>What All You Need To Do ? ...... as following</h3>
Step1). Create a WebLogic Cluster (minimum two ManagedServers)
http://weblogic-wonders.com/weblogic/2010/04/28/weblogic-clustering-in-remote-boxes/
Step2). Install a Proxy like Apache in frot of them like following:
http://weblogic-wonders.com/weblogic/2010/05/13/apache-proxy-as-static-content-repository/
Or
http://weblogic-wonders.com/weblogic/2010/08/01/weblogic-httpclusterservlet-proxyserver/
Step3). Now Configure a FrontEnd Host for your Cluster by providing the ProxyServer Host name as the FrontEnd of your Cluster. This step is required to Generate the Dynamic WSDL with the Address of the Frontend.(Not of a perticular WebLogic Server)
http://weblogic-wonders.com/weblogic/2010/06/21/configuring-frontend-host-and-port/
Step4). Deploy your WebService on the Cluster
Step5). Now Hit the WebService using the Proxy URL:
Example:
http://ProxyHostname:proxyPort/ServiceContextRoot/ServiceURI?WSDL

Getting error while calling Web service in PB 12.5

Hi All,
I am trying to call web service through my PB 12.5 but getting error like "Window sdk for .net framework 4.0 was not installed. please install befor use this feature." though I had installed window sdk . net framework 4.0.
one more thing do we required .wsdl file to call web service or only path is ok?
please help me out here.
Thanks,
Pralhad

Hi Pralhad,
From the Application Techniques manual, Building a Web Services Client, it states the following:
The WSDL file for you specify in the wizard or painter must have:
Services/Binding entries
The Targetnamespace
attribute defined in its Schema element
No circular references (an example of a “circular reference” is a structure
that includes itself as a child class member)
If PowerBuilder encounters a problem parsing the WSDL file, it reports the
error in an error message box.
Thank you.

Calling Web Service from PL/SQL in 9.2.0.4

We're having some problems getting the "Calling Web Services Sample from PL/SQL" sample working with our 9.2.0.4 database. After downloading the sample from http://www.oracle.com/technology/tech/webservices/htdocs/samples/dbwebservice/DBWebServices_PLSQL.html, we try to run the sample but get the following error stack:

Has anyone encountered a similar problem? Any help is much appreciated.
Todd.

the message looks very much like the one posted at http://asktom.oracle.com/pls/ask/f?p=4950:8:5812357525663697256::NO::F4950_P8_DISPLAYID,F4950_P8_CRITERIA:16568950771220
b.t.w. i don't think that any packages are missing. it seems that the XML is invalid. Did you use dbms_output commands to show the generated XML?

Calling Web service from Java Concurrent Program

Hi,
I created a Java concurrent program and created executable. Here is my code.
 public void runProgram(CpContext ctx) {
 String value = "Java Concurrent Program Testing";
 Hello hell = new Hello();
 String returnValue = hell.testURL(value);
 if(returnValue.equalsIgnoreCase("TRUE")){
 ctx.getLogFile().writeln("-- Java Concurrent Program Testing --", 0);
 ctx.getOutFile().writeln("-- Java Concurrent Program Testing --");
 ctx.getReqCompletion().setCompletion(ReqCompletion.NORMAL, "");
 else{
 ctx.getLogFile().writeln("-- Hello World! --", 0);
 ctx.getOutFile().writeln("-- Hello World! --");
 ctx.getReqCompletion().setCompletion(ReqCompletion.NORMAL, "");
 }testURL() call the web service and get the response. but when I am selecting View Output option I am always geting out put as
-- Hello World! --I tested the logic of calling web service. It giving me out put "true". Here is my Web service calling code
 public String testURL(String Value){
 HttpURLConnection httpConn = null;
 ByteArrayOutputStream bout = null;
 String setWebServiceURLResponse = "";
 String responseString="";
 String outputString = "";
 try{
 httpConn = getHttpConnection();
 bout = new ByteArrayOutputStream();
 String xmlInput = soapBodyStart +
 "<ns1:getTestURL>\n" +
 " <ns1:URL>"+Value+"</ns1:URL>\n" +
 " </ns1:getTestURL>"+
 soapBodyEnd;
 byte[] buffer = new byte[xmlInput.length()];
 buffer = xmlInput.getBytes();
 bout.write(buffer);
 byte[] b = bout.toByteArray();
 httpConn = setHttpConnectionRequest(b,httpConn);
 //Read the response.
 InputStreamReader isr = new InputStreamReader(httpConn.getInputStream());
 BufferedReader in = new BufferedReader(isr);
 //Write the SOAP message response to a String.
 while ((responseString = in.readLine()) != null) {
 outputString = outputString + responseString;
 //Parse the String output to a org.w3c.dom.Document and be able to reach every node with the org.w3c.dom API.
 Document document = parseXmlFile(outputString);
 String formattedSOAPResponse = formatXML(outputString);
 System.out.println("Formatted response = \n" +formattedSOAPResponse);
 //NodeList nodes = document.getElementsByTagName("setWebServiceURLResponse");
 //NodeList nodes = document.getElementsByTagName("getTestURLResponse");
 NodeList nodes = document.getElementsByTagName("ns0:getTestURLResponse");
 int len = nodes.getLength();
 System.out.println("Inside testURL Node Lenght = "+ len);
 for(int s=0; s<nodes.getLength() ; s++){
 Node authenticateResultNode = nodes.item(s);
 if(authenticateResultNode.getNodeType() == Node.ELEMENT_NODE){

 //System.out.println("Authenticate Response in getAuthenticate method : " + authenticateresponse);
 }//end of if clause
 }//end of for loop with s var
 System.out.println("Inside setWebServcieURLToFile response = " + setWebServiceURLResponse);
 catch(Exception e){
 e.printStackTrace();
 return setWebServiceURLResponse;
 }Where I am going wrong ?

Ajay Sharma

sample code:
static string url = "http://my.webservice.url"; ---------------> The actual web service URL
Call = new Call(url); --------------------------------------------------> The call object used by JAX-RPC
Object[] params = new Object[]{param1, param2};---------> build the call parameters
Boolean/Integer/Whatever result = call.invoke("method name", params);------>call the invoke method to get the result
