REST BASED WEBSERVICES

Hi,
We Have a Legacy System based on REST BASED WEBSERVICES, that legacy system can understand only HTTP format(it does n't support SOAP ) our scenario is HTTP TO RFC SYNCHRONOUS.
And we have to connect PI with REST BASED WEBSERVICES ?
1---->How can we connect PI with REST BASED WEBSERVICES ?
2---->and how to test those REST BASED WEBSERVICES ?any tool for that?
Thanks,
Nagaraju.

Hi Nagaraju,
you can sent message from PI via [http receiver adapter|http://help.sap.com/saphelp_nw2004s/helpdata/en/43/64dbb0af9f30b4e10000000a11466f/content.htm].
For message from legacy to PI use a simple address, what is explained in [SAP help http sender adapter|http://help.sap.com/saphelp_nw2004s/helpdata/en/43/64db4daf9f30b4e10000000a11466f/content.htm]
You can test http messages with Microsoft's tool [Wfetch|http://www.microsoft.com/download/en/details.aspx?id=21625] (in the net are hundreds of free ware http test tool available).

Udo

Securing REST based Webservices using OSB

Can anyone please lead me to any pointers on securing the REST based webservices.
Thanks,
KC

REST is more or less, a pure HTTP service so it is as secure as that. From my perspective transport security (basic authentication, SSL) is the basic security requirement for a REST based web-service. As far as message security is concerned, you may use custom HTTP headers to pass the tokens/digest but again it requires transmission over SSL to become an effective solution.
If you really have tight requirement from message security perspective, then I would suggest going to SOAP rather than using REST.

Consume a third party REST Based Webservice from PeopleSoft

We are in tools 8.49.33
Using 'Consume Web Service' component we can only consume a WSDL based webservice I guess. But we have a requirement to consume to a third party webservice, for which we just have to invoke a URL with query string via HTTP GET and receive an XML response. Has anyone done this before?

Three things to check:
#1: Check your errorLog.html file in the PSIGW web app of your PeopleSoft server
#2: Does your app server have to go through a proxy to connect to the internet? If so, did you configure integrationGateway.properties to use a proxy server? You can test this by trying to use ConnectorRequestURL for a plain old HTTP web site. If you get the same error, then it is likely a proxy issue.
#3: If #2 passed, then it might have to do with certificates and you will need to review PeopleBooks for importing certificates for integration broker. I haven't had to do this before, but am pointing it out in case.

SOURCING10: Passing parameters to a Query Based webservice using JAVA

Hi Experts,
I have been working on consuming a Query based webservice published in Souricng10 in a simple JAVA class. The query has a filter parameter which is not mandatory. I am able to consume the webservice using the GET method and display the content of the webservice. But when i try to POST a value to the filter parameter of the query i am getting the following error:

Hi Gael,
your URL is made up of :
[ProcedureName]?[parameter1]=[value1]&[parameter2]=[value2]
creating URLs like this can have problems especially with spaces and punctuation.
the answer is a FORM
the following will create a hidden form :
FORM ACTION="[ProcedureName]" METHOD="POST" name="F1"
INPUT type="HIDDEN" name="[parameter1]" value="[value1]"
INPUT type="HIDDEN" name="[parameter2]" value="[value2]"
/FORM
you can set the values in the form using:
document.F1.[parameter1].value="abc123%%&&$$!";
document.F1.submit();
will submit the form and the PL/SQL procedure should receive the text as it was contained in the form.
the only characters that can now cause problems are :
" as it delimits the field.
' as it may cause problems in PL/SQL.
\ as it is a special character.

Developing SOAP based Webservice using Axis 2 Eclipse plugin

Hi,
I want to develop a SOAP based Webservice which connects to the PostgreSQL DB , by fetching the data for the employeeId entered and display the results in the browser. I'm using using JDK 1.6, Tomcat 6.0, Axis 2.0 , with Axis 2 Eclipse Plugin. Please send me a sample code of how to build it, i am able find some examples on the internet, but none of them are related to connecting to the DB and fetching the data. It will be great if you guys can provide the sample application which does have the same functionality as mine. Please do respond as this is urgent. Thanks in advance..
Thanks,

Thanks Adhir Mehtaji, This is what i have come up with, developing a webservices based on SAAJ and deploying that in Tomcat server, here is the Webservice and the other related files:-
public class EmployeeService {
     * This method returns the Employee Name
     * @param empId String
     public void getEmployeeName(SOAPEnvelope req, SOAPEnvelope resp) throws javax.xml.soap.SOAPException {
          System.out.println("Inside the getEmployeeName in Employee Service");
          IEmployeeDAO employeeDAO= null;
          employeeDAO = new EmployeeDAOImpl();
          SOAPBody body = resp.getBody();
          String empId = null;
          NodeList empIdNodeList = req.getBody().getElementsByTagName("empId");
          for( int i=0; i < empIdNodeList.getLength(); i++ ) {
               Element empIdElementElement = (Element) empIdNodeList.item(i);
               Node empIdNode = empIdElementElement.getChildNodes().item(0);
               empId = empIdNode.getNodeValue();
               System.out.println("the empId in the employee service is:::"+empId);
          addNode(body,"empName",employeeDAO.getEmployeeName(empId));
          //addNode(body,"segmentName1",custSegmentDAO.getSegmentName(ZipCode));
     private static void addNode(SOAPBody body,String nodeName,String nodeValue) throws SOAPException{
          body.addChildElement(nodeName).addTextNode(nodeValue);
     This Service is exposed as a Webservice which connects to the DAO and get the response for the EmpId.
     This is the client file:-
     public class GetEmployeeNameClient {
          public static void main(String[] args) throws Exception {
               // Invoking the Webservice endpoint which is hosted (deployed) in Tomcat by passing the SOAP Message request

     This client will send a SOAPMessage with EmpId (100) as a request and get the response from the Webservice as SOAPMessage , which
     contains the empname for the respective empid which is passed.
I tested this service in the browser, it is up and running through the URL : http://localhost:8080/axis/services
But when i try to access the webservice to get the response from my client program, i am getting the following SOAP Fault string:-

Similary the in the d:/tomcat/webapps/axis/WEB-INF/lib,contains the same as that in client path.
I am using Tomcat 6.0 , JDK 1.6, I have googled and found that the expection is due to "Xerces.jar" not in Tomcat/webapps/axis/WEB-INF/lib.
I have copied xerces.jar in the said path, still the error persists. Please do provide a solution to this. Where i have gone wrong.
I have one more query, If i have to rest a "list" as a response from the server (webservice), how i can add the list into the SOAPMessage? Whether i need to parse it and add the values one by one in the SOAPMessage? like
<empname> xxxx</empname> <empage>25</empage>
<empname> yyyy</empname> <empage>26</empage>
Please answer these queries.
Thanks,

How to configure proxy services in OSB for Rest based services?

how to configure proxy services in OSB for Rest based services implemented using Jersey (Rest).
The Client need to contact OSB proxy servies by posting application/xml using jersey client and OSB proxy service will call the OSB business service.
i would like to know how to get this request in OSB proxy service and send it to the business service and get the response back.

I would suggest you refer to the below links:

Is there a way to consume REST based pdf web service in PeopleSoft

We have a requirement to consume an pdf REST based web service in PeopleSoft and display the pdf file on browser. I have configured the Service & Service Operation in PeopleSoft.
I have also confirmed the request is making to target server. Also when using curl, confirm the target web service is working and response seems to be binary bytes representing pdf file.
How can I consume this response from PeopleSoft message object. Tried using contentstring() and trying to do %response.write
   &getrpt_RESP = %IntBroker.SyncRequest(&MSG);
   &strresponse = &getrpt_RESP.GetContentString();
   %response.write(strresponse );
/* Open a file.pdf* - to do/
/* Write the response from message to file - to do */
/*Use view attachment to open the file on browser - to do*/
But this returns nothing on browser.
If I had to copy pdf file, I normally would use something like
   Local JavaObject &in = CreateJavaObject("java.io.FileInputStream", &SrcFullPath);
   Local JavaObject &out = CreateJavaObject("java.io.FileOutputStream", &filepath);
   Local JavaObject &buf = CreateJavaArray("byte[]", 1024);
   Local number &byteCount = &in.read(&buf);
   While &byteCount > 0
      &out.write(&buf, 0, &byteCount);
      &byteCount = &in.read(&buf);
   End-While;
But I am failing to find a way to copy the bytes from message to a file?
Any help is appreciated!

Integration Broker supports MTOM. You can find an example here: Sending and Receiving Binary Data.
The alternative is to use Java to make the HTTP request. You can use HttpClient, as Sasank mentioned, if you don't mind managing jar dependencies. The alternative is to use HttpUrlConnection directly. Not easy in PeopleCode, but possible. If you are on PeopleTools 8.53, then you can script it in JavaScript and run it on the server through the Rhino JavaScript script engine manager included with Java 7 and part of PeopleTools 8.53+. I find this MUCH easier because you don't have to deal with reflection.
Once you get the binary file, the next task is sending it to the client in binary format. %Response.WriteBinary works great, but requires you to start with binary data. I am only aware of one way to read binary data in PeopleCode that is suitable for %Response.WriteBinary and that is to select the binary data out of the database and into an Any variable. I have not figured out how to convert Java binary data into something suitable for PeopleCode's %Response.WriteBinary.

SOAP Based Webservices in Apex

Can you please let me if we can create a SOAP Based Webservices in Apex. Apex will be the provider of the webservice and my other 3rd party application will be consumer.

Thanks for the reply.
Now I am slightly understanding about web services. For example, If I place an order for an digital camera from a shopping site, can I route the order information from shopping site to APEX and from APEX can I process it further by integrating with paypal for online payments and get acknowledge from paypal that payment has been made and provide an acknowledgment to shopping site from APEX that order has been shipped to your shipping address. Is this possible? Please let me know regarding this..
Thanks and Regards,

Can I create JDE BSSV (Business Services) for REST based services?

Can I create JDE BSSV (Business Services) for REST based services? If yes, then how? In what way it will be different from SOAP based?

Hi
Within Oracle SOA Suite, Oracle Service Bus would handle the REST side of things, which in turn would call the JCA adapter to talk to your JDE backend, or vice versa.
Checkout the JDE adapter docs - http://www.oracle.com/technetwork/middleware/soasuite/documentation/jdewardsweb-1954164.pdf
and the OSB Docs - HTTP and Poller Transports - 11g Release 1 (11.1.1.7)
OSB 11.1.1.7 introduced additional REST support, so I'd recommend using that version onwards.
Cheers

How to inject EntityManager in non-EJB based WebService?

Hi,
I want to know how we can inject EntityManager in non-EJB based WebService?

I think the way to go would be to actually do use an EJB for the persistence stuff and use that EJB in your webservice. Use the right tool for the job and all that.

WSDL Parser [Is anyone else testing WCF-based webservices?]

I'm encountering the following message when attempting to force the use of the .NET parser when interrogating the WSDL of a new webservice:
Parsing specified wsdl...
Connecting to https://BLAH-BLAH/MobileTerminated.svc?wsdl
Validating https://BLAH-BLAH/MobileTerminated.svc?wsdl
.NET Parser could not parse https://BLAH-BLAH/MobileTerminated.svc?wsdl
Warning:Selected .NET Parser is invalid.
Must installed the .net sdk Framework.
Failed to parse https://BLAH-BLAH/MobileTerminated.svc?wsdl
Am I correct in interpreting this as "you need the .NET SDK installed in order to use the .NET Parser within OATS"?
I already have .NET framework 3.5(SP1) but not the SDK.
[UPDATE] It is probably significant that the webservice I need to test is WCF-based.

Edited by: IHodgetts on Jun 21, 2010 12:07 PM

I know I'm answering my own post here, but a lot of work has gone into this and someone else may as well benefit from my findings...
It would appear that OATSv9.10 does NOT support WCF-based webservices. The problem is apparently down to OpenScript not supporting WS-Addressing (part of Windows Communication Foundation) and this isn't currently scheduled for inclusion in v9.20 (much to my disappointment).
However, I have in the meantime found a workaround. Basically IGNORE what OpenScript populates the request with!
1) Use the OpenScript parser (the .NET parser will not work) to parse the WSDL.
2) Add the method(s) you require to the script.
3) The script will at this stage have two problems but can be used as a starting point.
Problem #1 - The content-type will need to be manually changed from "text/xml;charset=UTF-8" to "application/soap+xml; charset=utf-8". Edit this by right-clicking on the request and selecting "Headers" then "Content-Type".
Problem #2 - The contents of the request will not include the WS-Addressing information. One workaround is to obtain a working packet to replace this e.g. from a test harness for your WCF-webservice. Edit this by right-clicking on the request and selecting "Post Data". Replace the WHOLE string with a valid packet from your test harness.
Hopefully this will assist anyone else trying to get this working :-)

How to develop Asynchronous Document Based WebServices?

Hi gurus,
The scenario is, We are developing an architecture where Asynchronous Document Based WebServices are desired.
As per my knowledge, This architecture includes some
work at JMS side.
Meaning,
Client -
> Calling [WebService] -
> Deletgate --
>JMQ (Java Message Queue)
Would appreciate ur thoughts here...
Regards,
Arvind Kugasia [[email protected]]

Hi Arvind,
this "pattern" - sending JMS message and performing some long asynchronous tasks in MDB is a standard J2EE way.
That should be supported by any j2ee server that at least covers J2EE 1.3 (where MDB-s are introduced). That includes the SAP Web AS as well and its JSM and EJB implementation as well.
The message can be sent from a servlet, web service, etc.
In fact the classic petstore application released from sun as a model for developing J2EE applications uses MDB-s for that purposes :
http://java.sun.com/blueprints/guidelines/designing_enterprise_applications_2e/sample-app/sample-app1.3.1.html
Once you buy the parrot from the petstore, you will see the response page while the MDB will perform asynchonously the sending of the mail, charging of the account, etc.
It doesn't matter if the front end is a web service or a HTTP UI.
In addition you can google for any J2EE tutorial and MDB explanation.
However please note that I am speaking how your application will gather the parameters from the web service call, put them in a JMS message and send the message via several lines of java code.
Perhaps some other frameworks (Apache-Axis, etc.) are doing this automatically for you or are generating the code that sends the message via some wizard.
That up to my knowledge is not supported for SAP WebAS, but that is only a 10 lines of code inside the web service body, that can be easily created.

when i use the same url from the restClient (Firefox extension it works)
I have checked some blogs which talk about consuming rest srevices. most of them have a pre requisite to importing the security certificate of the service provider using the "strust" transaction.
Since i dont have authorization for that transaction, i was wondering if it is possible to call a rest service without importing the certificate.
Kidly suggest ways in which i can overcome this
Thanks and regards,
Saurav

It is not possible to make an HTTPS request without importing the certificate.
It works fine with HTTP request but for HTTPS we need to import the certificate and pass the SSL id.
