Web services - JAX-RPC/Axis/OC4J

Hi,
We are planning to expose some of J2EE applications as web service. It is based on JAX-RPC 1.0. I have checked it with Apache-Axis without changing any code and it worked. Will it work in OC4J without any code changes?
1. Does OC4J or Oracle SOAP server supports(or implements) JAX-RPC?
2. Do we need to change any code?

Right now we have a JAX-RPC 1.1 with JSR 109 support preview here on OTN at - this came out at OracleWorld:
http://otn.oracle.com/tech/java/oc4j/1003/content_preview.html
The target production date is summer 2004. There are also plans to do another drop of this preview with updated support later this year and possibly again before the production release.
We have quite a lot of functionality that we are targetting to flesh out our Web services support in the areas of reliability, orchestration, transactions and security.

PL/SQL Web Services - JAX-RPC returning in JSON format

Hello all,
I have been searching on the web, inclusively on this forum, for a way of returning data in a JSON format from a PL/SQL web service.
The threads that I have found about this issue are still unanswered.
Does anyone know if it is possible to create a JAX-RPC web service which returns in JSON format ?
Regards,
Pedro

Hi,
JAX-RPX services are SOAP services and thus return XML. You want to use REST instead

Web Service JAX-RPC/SOAP with JAXB

Hello,
During my research on JAX-RPC/SOAP as web service technology. I found only simple "helloworld" sample type what using simple String as aurgment. For my task, I required a more complex aurgment such as a complete contact info. I then did some sample code for JAXB and found it to be very useful as a XML/JAVA binding tool. It seems logical to use JAXB to parse and bind the complex aurgment. Though I have not seen any reference to this using it with JAX-RPC. Does JAX-RPC have the tool set to accomplish the same thing? JAX-RPC may have such thing, but using this JAXB seem logical, thus would I still "conform" to the JAX-RPC if I go this route. Any info would be much appreciative.
Thanks in Advance,
Mike

The two JAX-RPC tools that I have used, the reference implementation and Apache Axis both have tools for mappiing XML to classes and vice-versa. Having used JAXB also, I have to say that both of these tools are much easier to use than JAXB.
As far as whether it will conform, you can make a valid SOAP message using any tool you like.

Connect to SharePoint web service using the XML / Web Service connector

Hi experts,
I am currently trying to display my SharePoint list in Crystal Report. Therefore my plan is to use a SharePoint web service to get the data and paste them to the Crystal Report.
Is it possible to use the "XML and Web services" connector of the Crystal Reports database expert?
When I enter the web service URL, for instance:
https://[url]/_vti_bin/lists.asmx?wsdl
and click next... I have to enter the web service credentials.
On the next page I have to enter Service, Port and Method.
Do I have to enter the service URL again here?
What If, there is no port? Can I leave that field empty?
I know the methods, but where can I add the mandatory parameters?
Thanks for any helps and comments!
Sebastian

Hi Ananth,
thank you, but this document does not help at all.
We are using Crystal Reports 2008 SP2.
We want to use the Web Service Connector.
What I need is more informationen about the Web service connect. For example - the connection in Microsoft InfoPath is much easier - there I don't have to enter a port and can choose the methods from a list.
Is it possible to use the Crystal web service connector for MS SharePoint Webservices?
Or must I use the Crystal SDK to carry out a connection?
Best regards,
Sebastian

Failed to connect to VMware web service: Invalid keystore

Hi,
We have a CPO 2.3.1 that refuses to connect to vCenter (see log extract at the end of the post).
We recently changed our vCenter server (part of an update to 5.1).
We tried following workarounds:
remove and add all platform elements from the portal using SE services
re import automation packs (the 4 from the Starter Edition v2.3.1.38)
re set the keystore password
No change at all...
Would you have a clue on how to correct that?
Thank you.
Regards,
Pierre

You have an invalid keystore file because the HTTPS certification has changed. You need to delete the old keystore file and restart the CPO server and then reconnect/run something against vCenter.
There is also a possibility for Adatper Host Framework/java issues that I have seen commonly.
If you need more help, you'll need to open a TAC case with your services contract please. We normally try to not troubleshoot logs on the forums.

Problems connecting to php web service

Hello
I am pretty raw when it comes to using web services. I am facing a bit of a problem.
I have been given a url to a web service. http://41.208.61.35/legacyfallback/ws/legacyLifeWS.php?wsdl
I am trying to connect using cfinvoke:
<cfinvoke webservice="http://41.208.61.35/legacyfallback/ws/legacyLifeWS.php?wsdl" method="test" returnVariable="result"> </cfinvoke>
<cfoutput>#result.test#</cfoutput>
I keep getting the following error:
Cannot generate stub objects for web service invocation.
Name: http://41.208.61.35/legacyfallback/ws/legacyLifeWS.php?wsdl. WSDL: http://41.208.61.35/legacyfallback/ws/legacyLifeWS.php?wsdl. java.io.IOException: Type {http://www.w3.org/2001/XMLSchema}char is referenced but not defined. It is recommended that you use a web browser to retrieve and examine the requested WSDL document to ensure it is correct. If the requested WSDL document cannot be retrieved or is dynamically generated, it is likely that the target web service has programming errors.
Please can someone assist me in getting around this.
Have a look at the service url if you need to.
Ive been at it all day and im ready to pull my hair out!
Thanks in advance

Hi
Ok now i am using the following code:
<cfinvoke webservice="http://41.208.61.35/legacyfallback/ws/legacyLifeWS.php?wsdl" method="register" returnvariable="registerRequest">
    <cfinvokeargument name="wsUserName" value="delon">
    <cfinvokeargument name="wsUserPass" value="cheketri">
    <cfinvokeargument name="mobileNumber" value="0834064488">
    <cfinvokeargument name="name" value="delon">
    <cfinvokeargument name="gender" value="M">
    <cfinvokeargument name="birthDate" value="01-01-2010">
    <cfinvokeargument name="merchantid" value="0">
    <cfinvokeargument name="email" value="[email protected]">
</cfinvoke>
and getting the follosing error:
Web service operation register with parameters {mobileNumber={0831727737},name={hansie},wsUserPass={smit},birthDate={01-01-2010},gender= {M},email={[email protected]},wsUserName={delon},merchantid={0}} cannot be found.
WHy would that be?
I checked with the provider and the var names are correct.

An error occurred while trying to connect to a Web service, when InfoPath web enabled form loads.

Hi Everyone,
I am getting an error message: An error occurred while trying to connect to a web service, when my InfoPath form tries to load. The last few days, it only spits this error message in the morning and around 12pm-1pm it resolves itself and the form loads
fine the rest of the day, oddly enough.
A few things about my form:
1). It is web enabled
2). The form submits to a form library on the SP server
3). I use the UserProfileService data connection in the form to auto-populate a few fields
4). I use a udcx file with correct language stored in the root of the site collection in the data connection library
5). The form has been working fine until a few days ago
I noticed while in Central Administration, that the User Profile Service Synchronization is Stopped. Not sure if this is causing some or all of the problem. If I need to start it I will need to contact my farm administrator to do this, since I do not
have the service account information.
Also, I looked thru the log files on the SharePoint server and found the following by searching for the Correlation ID shown when the error comes up, I won't put in everything just the important messages.
Schema file was already loaded: BuiltInActiveXControls.xsd
FormServer Partial Trust - Proxy operation invoked in the SHIM process.
FormServer Partial Trust - Invoking proxy operation for Web service adapter failed with exception Operation is not valid due to the current state of the object. for Url=https://<SP URL>/_vti_bin/UserProfileService.asmx
Data adapter failed during OnLoad: The custom code in the form cannot be run. This functionality may be deactivated on the server. For more information, contact the server farm administrator.
The following query failed: GetUserProfileByName (User: , Form Name: Expense Report, IP: , Connection Target: <SP URL>/Data Connections/GetUserProfileByName.udcx, Request: , Form ID: urn:schemas-microsoft-com:office:infopath:Expense-Report:-myXSD-2014-04-11T21-06-32
Type: DataAdapterException, Exception Message: The custom code in the form cannot be run. This functionality may be deactivated on the server.

Hi B.,
You are on the right track. I recommend that you first get the User Profile Synchronization Service started because that itself could be the root cause of the issue.
If that doesn't fix it then focus your attention on the GetUserprofileByName data connection. I always use my secure store ID for this connection. I add the ID by editing the udcx file and then publishing it again.
Hope this helps.

Laserjet Pro 400 MFP M425DN Can not connect to HP Web Services

I have a Laserjet Pro 400 MFP M425DN printer on a network running windows 7 and we Can not connect to HP Web Services. When we use the display on the menu it comes back with error "Internal Processing error, try again or check firmware update" We installed the new firmware but still get the same message. IF type in our printers IP address into our browser we get the info on our printer but if we go to the HP web services tap and click enable it trys but come back with a "connection error"
Any ideas?
Thanks
Paul

I just updated my Firmware on this printer today to the latest version dated May 3 2013 and Web Services
worked. Had the same type of problem you had for months and had worked with HP but could never get
Web Services to work at my location with my Modem/Router.
Had tried at other locations and it would work with the old Firmware. But for some reason it did not at my
location with the Modem/Router I was using.
Again the latest Firmware fixed it. I tried all the other solutions that I had found on the internet and non of them worked.

Is it possible to call an external web service using ABAP?

Hi~~
I wonder that is possible to use an external web service in SAPGUI using ABAP without PI ( Process Integraion ).
The external web service means the service that is developed by web-language like ASP.NET.
Thank you.

hi,
i'm trying to study on how to use the oracle bi publisher using another client application aside from oracle. the client application is custom and uses a .Net framework. unfortunately, i am not familiar with how .Net sends requests to oracle bi publisher so i was thinking that may be i can just create oracle pl/sql stored procedures that can send this requests over to bi publisher.
p.s. when you said concurrent manager, i'm not sure if you are referring to oracle apps concurrent manager but if you are, unfortunately i won't be using oracle apps with bi publisher.
thanks

Cannot submit sharepoint form due to error. An error occurred while trying to connect to a Web service. Please Help!

An error occurred while trying to connect to a Web service.
An entry has been added to the Windows event log of the server.
Log ID:5567
Correlation ID:4db21044-cbc4-4f2f-8653-d73e5496b891

check the log file first to get detailed information, go to ULS log file, find the related Correlation ID, you will get the error message, the information you provided is less helpful to know this issue.

Hi Jithendar,
If you can send the ULS log entries which has that Correlation ID, it would be more helpful.
The text you send is only the ID of the entries and dont give any clue to us about your problem.

*σ* Use [javax.xml.soap|http://java.sun.com/javaee/5/docs/api/javax/xml/soap/package-summary.html] package for invoking web services using Simple Object Access Protocol (SOAP). Using SOAPConnection you can connect and communicate to a webservice via SOAPMessage . [More about SOAP Connection|http://java.sun.com/javaee/5/docs/tutorial/doc/bnbhg.html#bnbhq].
*σ* Use [java.net|http://java.sun.com/javase/6/docs/api/java/net/package-summary.html] package for invoking web services using Hypertext Transfer Protocol (HTTP). Using HttpURLConnection you can connect and communicate to a webservice.

How to connect to a web service??

I am banging my head on how to produce the appropriate code
to connect to a
web service I created locally.
I have a local web service:
http://localhost:8500/cfc/getprojects.cfc?wsdl
I am trying to figure out how to write a correct
<mx:WebService> to connect
to it so I can go on and bang my head on how to then bind the
results to
Labels.
I am attempting to follow the manual on this topic but it
goes all over the
place and my newbie mind can't wrap my head around it.
I tried this:
<mx:WebService id="get_projects"
wsdl="
http://localhost:8500/cfc/getprojects.cfc?wsdl"
useProxy="false"/>
</mx:WebService>
But I keep getting: The prefix "mx" for element
"mx:WebService" is not
bound.
I tried to find out more about it and thought I had to add:
<mx
peration name="getProjects">
<mx:request>
<projecttitle>????</projecttitle>
</mx:request>
</mx
peration>
But I have no idea on what to put in the request section per
each title
(<projecttitle>
And anyone show me how to write a correct
<mx:WebService> statement to be
able to connect to my web service?!
And if anyone is really bored:
The query results in 5 fields of data (project_title,
p_height, p_width,
p_type, live)
How do I then bind the project_title results to a label?

Do you have a namespace declaration for mx in the root tag of
the file
that contains the WebService tag? For example, if you're in
the main
application file, your root tag should look something like:
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"

Failure to connect to a web service.

hi guys,
I am trying to connect to a web service but i keep getting the following errors:
<faultcode>soap:Server</faultcode>
<faultstring>Server was unable to process request. --> Value cannot be
null.
Parameter name: s</faultstring>
My guess is that it is to do with converting java unicode to utf-8..
Please help.

Can you access that web site via other browser like IE ?
