Reading xml in web services

I m sending an xml as string to the web service and i want to read the xml using JDOM but its not working. IS there any way of reading the xml in web service
thanks in advance

I'm trying to do the same thing in WASD 5.1 (which in theory conforms with JSR-109) and it is proving very difficult.
Why is letting the Web Service implementation do the "heavy" work ( checking the SOAP message against the WSDL, performing security checks) but then AVOIDING the default mapping process so difficult.
The next bit is to vent my frustation:
"The lack of documentation on this subject is unbelievable, lots of 'you can then implement a document-centric web service' but without a single, real world, worked through example.
For some reason parsing a bit of XML is seen as an extremely difficult task that should be avoided at all costs - oh come on!!! "
Ok, venting finished, now for the question:
Has ANYONE successfully imlemented a document-centric Web Service and can offer their experience/solution to the world?

OWSM 10.1.3.4 and Non-SOAP XML-based web service

Hi all,
According to the OWSM 10.1.3.4 Administrator's Guide, "all Web services registered with an Oracle WSM Gateway are virtualized as both a SOAP and non-SOAP Web service." To access the non-SOAP (XML-only) web service, the documentation states "The non-SOAP virtualized URL can be determined from the virtualized SOAP URL by replacing the services keyword in the URL with the xml keyword."
For example, if the SOAP virtualized endpoint is:
http://host:port/gateway/services/SID0003001
then, the non-SOAP XML service endpoint is:
http://host:port/gateway/xml/SID0003001
I have several web services registered with an OWSM gateway, running on SOA Suite 10.1.3.4, and can access those without any problem. However, when I attempt to access the "/gateway/xml" version of these services, I simply get an HTTP 200 response header with a null body.
Does anyone have any ideas what could be causing this or what the secret is to get the non-SOAP XML service feature of OWSM to work?
Thanks!

Sending document to oracle xml gateway web service and body is url encoded

Hello,
a question from a complete newbie to web services. I have some code that is sending a soap message to an oracle xml gateway web service. In the soap message the values in the soap body look like &lt ;CNTROLAREA&gt ;
when I would be expecting <CNTROLAREA>. What I have been told is that the content of the ReceiveDocument element has been url encoded which causes the &lt and to correct it I need to change the paramater type from object to xmlnode and to build the request as an xmldocument. The xmlnode and xmldocument comes from a .net guy so I've been trying to find the equivalent in java but am not having any luck. I have a lot of reading to do but was wondering if someone might be able to point me in the right direction on how to correct the problem. I captured the soap message being sent using tcpmon. Why does the body have the &lt instead of the < as I was expecting and is there an xmldocument type? The header part of the soap message looks as I expect. "><soapenv:Header><ns1:XMLGateway_Header xmlns:ns1="http://xmlns.oracle.com/apps/fnd/XMLGateway"><ns1:MESSAGE_TYPE>XML</ns1:MESSAGE_TYPE>. It is being sent as a com.oracle.xmlns.apps.fnd.XMLGateway.XMLGateway_Header type.
thanks
Thanks

The xmlnode and xmldocument comes from a .net guy so I've been trying to find the equivalent in java but am not having any luck. How do you get the data from .net guy? Which interface do you use? What processing do you do after receiving the data?

Using Native Oracle XML DB Web Services - REST POST web service possible?

My goal is to expose some pl/sql procedures as a REST web services.
The Database is 11gR2
The request method needs to be a POST (not GET as a request will perform insert/updates ) - the request body will contain a xml structure
Have setup XMLDB Database-native Web Services as per
11g documentation "Using Native Oracle XML DB Web Services"
It seems this setup support only SOAP requests!?
RESTful webservice with GET is (sort of) supported using
Embedded PL/SQL Gateway as describer here:
http://ora-00001.blogspot.com/2009/07/creating-rest-web-service-with-plsql.html
Although no support for POST
Obviously the post is from 2009 so just want to know if anything changed since.
Has anyone found a way to expose pl/sql procedures using XML DB or other approach as a REST POST web services?
(As the relative low number of calls/hour and also the aim to have the least amount of moving parts therefor looking for a DB centric solution)
Thanks
Pete

I think the post referred to was more an exercise of what could be achieved. The quickest way, nowadays, to get this done with not too much hassle is via APEX

JSON+XML RPC Web service

Hi,
i want to consume JSON/XML RPC webservice from Strobe media playback.
How i would achieve this.

A google search of XML-RPC turned up this:
http://mxblogspace.journurl.com/users/admin/?mode=article&entry=763
and this:
http://www.activsoftware.com/resources/support/messages.cfm/id/5484
I don't think you will be able to invoke an XML-RPC web
service using the standard <cfinvoke webservice="..."> due to
the fact that the URL for an XML-RPC webservice is not a WSDL file,
which is what coldfusion is expecting.

XML and Web Service Data Source Missing in Crystal Reports for VS

I would like to use a Web Service as the data source for a Crystal Report that will be running outside of my Visual Studio application. So setting the data source to the web service in code is not possible. My understanding is Crystal Reports has a connection (in the Database Expert under New Connection) named XML and Web Service. Here you can select web service and enter the WSDL URL for the web service. However it does not appear in the list for Crystal Reports for Visual Studio. Does this connection type come with the Visual Studio version of Crystal Reports and if not is their a way to obtain it?
Thank you for your assistance.

None of the bundled versions of CR have the driver. Reason is that the driver responsible for these connections requires the Java framework and I suspect MS would not be too pleased if we installed the Java framework. The stand alone versions, since they are not part of any bundle can and do install the Java framework and the driver. Note that even the latest release of CR - CRVS2010 does not have the driver as it essentially becomes a bundle or a VS2010 plug-in.
So, the short of it is; you have to obtain a stand-alone version of CR. I'd recommend CR 2008 (12.x) as CRXI R2 will run out of support in June of this year.

Hi Ag,
To my knowledge, the only information on this topic is whatever you find in the

How to pass xml in Web Services

Hi,
Can some one suggest which is the best way to send xml in web services.
It can be sent as string (CDATA) or attachements.
Is there any other way, may be as some object??
I would appreciate if someone can help me on this.
Thanks & Regards,
Rana Biswas

Hi, Eric,
Thank you for your quick reply.
The web service I am trying to develop is basically a generic Data Access Component to bridge between SQL server and a desktop .Net application. The application will have about 3000 users from WAN, therefore we want to have a server side component to handle connection pooling etc. Because of limitation of current servers, we are asked to develop a Java Web Service, instead of MS WS.
To make the component more reusable, I am thinking to have methods like this in the service:
RunQueryReturnRS(String Sql, WebRowSet, rs)
RunQueryReturnInt(String Sql, int NumRecdImpacted)
RunStoredProcedureReturnRS(â¦.)
RunStoredProcedureReturnInt(â¦.)
â¦â¦
You see, I would like to get whole resultset back to client, including both metadata and data in a format of generic resultset. When I paged through the Sunâs document, finding WebRowSet is claimed to be seariable, and ready for Web Service. I thought if I can use WebRowSet that will save me time to write new classes to hold resultset info and pass back to client.
Could you please tell me if it is a feasible approach?
Thank you.

XML Header Web Services 8.6

I am developing an HTML application using LabVIEW Web Services in version 8.6. I configured a VI to output data as XML. I am using the jQuery framework for javacript at this time. I noticed that when I try to get the data from this VI as XML jQuery won't load load it (might be having the same issue with prototype). After running a packet capture this is what I found the data from LabVIEW to look like:
HTTP/1.1 200 OK
Date: Tue, 18 Aug 2009 13:55:03 GMT
Server: Mbedthis-Appweb/2.3.0
Cache-Control: no-cache
Content-type: text/xml
Content-length: 87
Connection: keep-alive
Keep-Alive: timeout=60000, max=98
<Response><Terminal><Name>read_buffer</Name><Value>13.509</Value></Terminal></Response>
So it seems that the <?xml version="1.0"> tag at the top of the document is not being sent out and I have to add this manually to my javascript code before it works. Is there anyway to force LabVIEW to send this out on the server side? My javascript code:
<script type="text/javascript" src="js/jquery.js"></script>
<script>
$(document).ready(function(){
  $.get("../LambdaWeb/lambda/read_volts", null, function(data){
   var xml = $('<?xml version="1.0" ?>' + data);
   alert("Data Loaded:" + xml);
  }, "xml");
</script>
Also on a side note. I know that JSON is now available in LabVIEW 2009; is there anyway to get JSON support for 8.6?

Is there any way so that one can send data (array 'DBL' & about 60,000 elements) after converting it to a string using 'Flatten to String' function and not using 'Flatten to XML'?
Reason behind using 'Flatten to string' is the size of flattened data is much lesser that it would be in later case.
I am not allergic to Kudos, in fact I love Kudos.

Problem parsing xml(J2ME Web Service spec) containing image in cldc/midp

Hi,
I have created a restful web service that generates xml file in app server. I have created xml file using JAXB2.1 spec. This xml file has many elements starting from char data to image (binary data). I could successfully create xml file and developed another test client to read the same file using JAXB. However, I am finding a problem while getting the image in the java me client (cldc1.1 and midp2.0).
I am using J2ME Web Services Specification, using javax.xml.parsers.SAXParser to parse the xml file. Parsing is successful and got the character data. But the image data is not accurate, so I am not getting the image. I suspect the problem is with encoding but not sure how to solve this. At the server end, I verified that xml file is encoded with "UTF-8" encoding, not sure how to decode at the client end.
I am totally confused as how to get the accurate image data, not sure if I use kxml parser would solve my problem.
I would really appreciate if somebody can get back to me as this is very very important.

Try to send to your web service the byte array instead of string and then convert the byte array into an image
using a method like the following one in your service:
// C# code
public Image ByteArrayToImage(byte[] byteArrayIn)
     MemoryStream ms = new MemoryStream(byteArrayIn);
     Image returnImage = Image.FromStream(ms);
     return returnImage;
}There can be some problem between encoding in J2ME and .Net so try different encodings in gathering the image bytes in your j2ME application, but, instead of jpg which has more encodings, try png that is a more standardized image compression(open standard).

How and when to load cross-domain.xml for web services.

I'm accessing some 3rd party web services and so I need them to have a cross-domain.xml file, which they have done.
In order to access their web services, am I correct that I need to load the cross-domain.xml file they put on their web server, and if so, is my code to do so below correct, which I put in my creationComplete handler function?
Note, of course the IP address in my code is not 0.0.0.0.
Do I need all these lines, and am I doing this correctly?
Currently I am getting a SecurityErrorEvent.
Security.allowDomain("0.0.0.0");
Security.loadPolicyFile("http://0.0.0.0/crossdomain.xml");
var request:URLRequest = new URLRequest("http://0.0.0.0/crossdomain.xml");
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, policyLoaded);
loader.addEventListener(IOErrorEvent.IO_ERROR, policyIOError);
loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, policySecurityError);
loader.load(request);

Okay, I found that when I put the crossdomain.xml file at the root of my web site file area my hosting company provides, I do not specifically need to load the crossdomain.xml file.
But if I want finer control over who has access to what, and I put the crossdomain.xml file in the same directory as my Flex app SWF file, what lines of the following code (or additional lines I don't know about) should I put in my app creationComplete handler function to load the crossdomain.xml file?
Note, of course the IP address in my code is not 0.0.0.0.
Do I need all these lines, and am I doing this correctly?
Security.allowDomain("0.0.0.0");
Security.loadPolicyFile("http://0.0.0.0/myAppFolder/crossdomain.xml");
var request:URLRequest = new URLRequest("http://0.0.0.0/myAppFolder/crossdomain.xml");
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, policyLoaded);
loader.addEventListener(IOErrorEvent.IO_ERROR, policyIOError);
loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, policySecurityError);
loader.load(request);

NPE when working with connections.xml for Web Service client

Our ADF Web Service clients needs to read the WSDL and End point URL from connections.xml. But this is giving an Error.
Here are the details:
jdevloper 11.1.1.6.0
Weblogic 10.3.5
OWSM 11.1.1.6
From my ADF based Application I need to call out a web service.
For this I have built a Web Service Proxy and coded to call it from the application.
Since the app needs to run through the development testing deployment lifecycle and hence be deployed on different environments, we need the ability allow configuration of wsdl and end point URL for the web service call without the need to recompile the app.
We want to leverage the connections.xml for this purpose.

Hi Frank,
I got the following two lines of code just to check if WebServiceConnection was able to read the connections file alright.
            String urlString = wsc.getWsdlUrlStr();
            System.out.println("WSDL URL: "+urlString);
I am not using urlString for further processing.
The output is
WSDL URL: http://<host>/PSIGW/PeopleSoftServiceListeningConnector/MyService.1.wsdl
java.lang.NullPointerException
        at java.lang.Class.isAssignableFrom(Native Method)
        at oracle.j2ee.ws.common.jaxws.runtime.GenericJavaType.create(GenericJavaType.java:97)
        at oracle.j2ee.ws.common.jaxws.runtime.GenericJavaType.create(GenericJavaType.java:118)
The WSDL Url pointed to is the one that I configure in the connection while deploying the App.
Ran a test and WSDL Url is accessible by the app.

Web.xml and web service

In a web.xml file there is a section:
*<service-ref>*
<service-ref-name>xxxx</service-ref-name>
<service-interface>x</service-interface>
<wsdl-file>WEB-INF/x.wsdl</wsdl-file>
<jaxrpc-mapping-file>WEB-INF/x.xml</jaxrpc-mapping-file>
<port-component-ref>
<service-endpoint-interface>xxxxxxxx</service-endpoint-interface>
</port-component-ref>
*</service-ref>*
I have two questions:
1)To use web service, is this section mandatory or optional?
2)If optional, what is this section used for?
Thanks
Scott

With JAX-WS this is not required.
