APEX Web Services Proxy Settings

So I have been experimenting with Web Services and I see to have a problem whenever I go through a Proxy Server; I keep getting the error below for the same request that works when I am not using a Proxy Server.
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at "APEX_040000.WWV_FLOW_WEB_SERVICES", line 959
ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00202: could not open "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" (error 101) Error at line 1I am thinking that perhaps its because the Proxy Server I am using requires authentication; however, I cannot seem to find a provision for username/password when editing the definition.

Hi Phiri,
the web services call will be made by the database server, so authentication isn't just an issue for APEX, but you would give the host running the database server access.
APEX itself only supports the simple proxy case just to provide the basic functionality.
Depending on which web server you use to host APEX, you might be able to let that host pass your proxy attributes with the request (e.g. when using OHS, you could put the values into PlsqlCGIEnvironmentList), though I'm not sure whether they are forwarded for web service requests automatically or if you have to build your own process to extract the value from the CGI environment and add it to the web service call.
Another option could be to start building the process in your own process right away. The database has the API-package UTL_HTTP which can be used to perform the proxy authentication (utl_http.set_authentication with for_proxy => true)
Have a look on these pages:
- example for a request including proxy and authentication (with the little change to be "for proxy") http://www.oracle.com/technology/sample_code/tech/pl_sql/htdocs/x/Utl_Http_Package_Enhancements/Cr_Using_Utl_Http.htm
- a nice overview on the package methods: http://psoug.org/reference/utl_http.html

WEB SERVICE PROXY GENERATED USING 11.1.1.5.0 WSDL FAILS WITH 11.1.1.6.0

I have created a Web Service Proxy project in Jdev using BI Publisher 11.1.1.5.0 WSDL (ReportService). Generated ReportService_Service method uses following QName to get the port:
namespaceURI = "http://xmlns.oracle.com/oxp/service/v2"
localPart = "*v2/ReportService*"
Reports are generated successfully via Web Services when using BI Publisher 11.1.1.5.0 but when I use BI Publisher 11.1.1.6.x, it fails with this exception:
+'javax.el.ELException: javax.xml.ws.WebServiceException: {http://xmlns.oracle.com/oxp/service/v2}v2/ReportService is not a valid port. Valid ports are: {http://xmlns.oracle.com/oxp/service/v2}ReportService'+
I noticed that if the Web Service Proxy project is created using BI Publisher 1.1.1.1.6.0 WSDL (ReportService), the generated ReportService_Service method uses following QName to get the port:
namespaceURI = "http://xmlns.oracle.com/oxp/service/v2"
localPart = "*ReportService*"
We are supporting both 11.1.1.5.0 and 11.1.1.6.x, so is there a way to make it work with both.
FYI, I have tried removing v2 but then it only works with 11.1.1.6.0 and fails with 11.1.1.5.0.
+Caused By: javax.xml.ws.WebServiceException: {http://xmlns.oracle.com/oxp/service/v2}ReportService is not a valid port. Valid ports are: {http://xmlns.oracle.com/oxp/service/*v2}v2/*ReportService+

Dear,
found the solution (after trying last 1-2 days ...).
I was already using java 1.7 update 7.
I had to start java settings and to deselect Java 1.7.0_07.
Instead I selected latest Java version from Apple: 1.6.0_35-b10-428.
With these settings the installer finishes without crash.
Kind regards

Help needed creating Web Service Proxy with SSL

Hi All, I really need your help. I need to create a Web Service proxy for a web service which is SSL enabled and developed in Netbeans. I have been given keystore as well as certificates files and I have copied "keystore.jks" in my c:\Documents and Settings\<user> and the certifcates to <JAVA_HOME>\jre\lib\security\cacerts. Now when I run the Proxy creation wizard and give the location of the WSDL file, JDeveloper gives an error "Error importing schemas: Default SSL Context init failed: Invalid keystore format". Can anyone please guide me what I am doing wrong here. I will appreciate your help.
Thanks in advance.
John

I am using JDeveloper 10.1.3.3.0. Thanks Heaps

URGENT - Deployable Web Service Proxy gets an unauthorized message

Hello Guys!
I had developed a <i>deployable web service proxy</i> that is called from a servlet. The web service is secured by a basic authentication. My servlet instantiates the proxy and I set the stub like the code bellow:
Maintenance myMaintenance = (Maintenance)ctx.lookup("java:comp/env/MaintenanceWSProxy");
MaintenanceViDocument port = (MaintenanceViDocument)myMaintenance.getLogicalPort("MaintenancePort_Document", MaintenanceViDocument.class);
port._setProperty("javax.xml.rpc.security.auth.username", "user");
port._setProperty("javax.xml.rpc.security.auth.password", "password");
But when I call the servlet, an exception is thrown:
407 - Unauthorized
Somebody knows what is happened?
Thanks a lot!
Best regards,
Marcelo

Hello Marcelo,
i've got an impression that the return error code is related to servlet itself.
Was the servlet deployed as a portal application or as pure j2ee (via SDM or via portal support page)?
Are you accesing it through portal framework or by a direct link to j2ee application?
If it is an portal application - you need to set security policy for iView or for the application (depends on the way you use it. Via iView or via direct link)
If it is an pure j2ee application, then you can define your security roles within the project. First of all, check those settings. Second step is done in VisualAdmin, where you map objects from UME to your security role defined in project.
hope it helps.
regards
mz

OWSM custom step & web service proxy

Hello!
I'm writing custom step, in which I want to call methods from another web services. So I generated in JDev (i'm using 10g) Web Service Proxy, I have all needed classes generated,
and I want to use it in my custom step (i.e. invoke some method). But when I try to build .jar I get errors like this:
[javac] C:\Documents and Settings\admin\Pulpit\My Dropbox\my_apps\Laboratoria\PEP\src\pep\proxy\runtime\PDPConnectorPortBinding_Stub.java:61: cannot find symbol

[javac] location: class javax.xml.soap.SOAPMessage
[javac] _state.getMessageContext().getMessage().setProperty("DimeEncode",_getProperty(ClientConstants.DIME_ENCODE_MESSAGES_WITH_ATTACHMENTS));
what is the problem? some classes incompatiblity? I tried to use jdk 1.5 and 1.6...

Hi,
Are you accessing teh WSDl from a deployed service ? If yes, when providing the Web Service URL, did you extend the URL with ?WSDL ?

11G - XDB Native Web Services - how to create a web service proxy

Hi,
I am working on XDB Native web Services (http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28369/xdb_web_services.htm#CHDDBCHB). I want to create a proxy web service for orawsv service (http://server:port/orawsv?wsdl), which is protected by an user/password
In Jdeveloper 10133:
+ copy orawsv wsdl (http://server:port/orawsv?wsdl) in local file
+ create a proxy web service form the local wsdl (from the wizard)
+ implement the client (http://www.oracle.com/technology/obe/11gr1_db/datamgmt/xmldb2_b/xmldb2_b.htm)
==> OK
In Jdeveloper 11g
+ copy orawsv wsdl (http://server:port/orawsv?wsdl) in local file
+ create a proxy web service form the local wsdl (from the wizard)
+ how to implement the client : there is no method to set a password
any ideas?
Thanks for your help,

I'm working on getting a proxy web service working in 11g and the contents of this thread is close to answering my question.
The web service proxy is accessing a service that requires a SOAP Security header.
In looking at the previous post, I thought that by using the BindingProvider API I could add the security settings. But when I invoke the proxy I consistently get the following error response from the (PeopleSoft) web service: "com.sun.xml.ws.client.ClientTransportException: request requires HTTP authentication: Unauthorized'
In contrast to that error, when I use JDeveloper's HTTP Analyzer, I get a successful response from the web service. Below is what the raw HTTP looks like:
POST https://isiswebdev.services.wisc.edu:7002/PSIGW/PeopleSoftServiceListeningConnector HTTP/1.1
Content-Type: text/xml; charset=UTF-8
Host: isiswebdev.services.wisc.edu:7002
SOAPAction: "CI_U_FA_CSA_STDTA_CI_G.V2"
Content-Length: 548
X-HTTPAnalyzer-Rules: 1
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:ns2="http://xmlns.oracle.com/Enterprise/Tools/schemas/M183895.V1">
<env:Header>
<ns1:Security>
<ns1:UsernameToken>

<ns2:EMPLID>012345678912</ns2:EMPLID>
</ns2:Get__CompIntfc__U_FA_CSA_STDTA_CI>
</env:Body>
</env:Envelope>
Here's the Java code that I'm using to try to make the same call:
public void callIWebservice(String emplId){
cSA_STDNT_DATA = new CSA_STDNT_DATA();
CI_U_FA_CSA_STDTA_CI_PortType port = cSA_STDNT_DATA.getCI_U_FA_CSA_STDTA_CI_Port();
Map<String, Object> requestContext = ((BindingProvider)port).getRequestContext();
requestContext.put(BindingProvider.USERNAME_PROPERTY, "UserName");
requestContext.put(BindingProvider.PASSWORD_PROPERTY,"XXXXXXX");
GetCompIntfcUFACSASTDTACITypeShape CiType = new GetCompIntfcUFACSASTDTACITypeShape();
EMPLIDTypeShape emplIDType = new EMPLIDTypeShape();
emplIDType.setValue(emplId);
CiType.setEMPLID(emplIDType);
try {
GetCompIntfcUFACSASTDTACIResponseTypeShape response = port.getDATA(CiType);
System.out.println(response.getCUMGPA());
} catch (M464939V1 e) {
System.out.println(e.getFaultInfo());
But, alas, I just get the ClientTransportException.
Is the Bindingprovider interface the correct way to add the soap security headers? Or am I following the wrong path?
Any help will be greatly appreciated.

Web service proxy and data control are not working properly

Hi,
I am working on jDeveloper 11.1.1.6
I have a SOA web service which requires 3 inputs and return with a set of data.
When I tried testing that web service in soapUI it is working perfect. But when I have created a web service proxy in my application and trying to test it from class (*******_ptClient) main method everytime it is replying with the output null
Also When I am requesting from the main method SOA is getting proper input (which I am providing in the main method) and SOA is returning proper output I have checked the SOA instance in em. So there is no problem in SOA side.
After that I have created web service data control and tested in that case also it is not showing any result.
What could be the problem ?
Please help.
Thanks
--NavinK

Hi Shay Shmeltzer,
Thanks for the reply.
I tried in HTTP Analyzer in JDeveloper and there also it is not working. My concern is :-
There are many other web services deployed on the same SOA server in same partition and they are working fine in HTTP analyzer and I am able to create and use the web service proxy as well. So as per my understanding there is nothing like network issues between SOA server and jDeveloper.
1 more thing When I am creating the proxy for this web service and requesting from the proxy's main method SOA is getting proper input (which I am providing in the main method) and SOA is returning proper output I have checked the SOA instance in em. So there is no problem in SOA side. The problem is jDeveloper is not able to get back that response which SOA is returning.
Please Help.

Validation error while creating Web Service Proxy.

Hi,
I'm trying to create Web Service Proxy. But I'm stuck with a Validation error
model error: type
+"{http://xmlns.oracle.com/2001/XMLSchema/DOM}+
+org.w3c.dom.Document" not found.+
I'm using "Create Web Service Proxy" wizard. There are 6 steps in creating proxy through JDev. wizard.
First step itself displaying the above validation error when I click on "Next" button.
Few points
We have created web service using "oracle.j2ee.ws.StatelessJavaRpcWebService" servlet
Thanks in advance.

Hi,
It might be that the .net service which you have is not WS-I compliant. Can you first run WS-I Analyzer on the wsdl to see it the test passes.

Error creating web service proxy for bpel process in jdev 10.1.3

Hi,
I am trying to create a web service proxy in Jdeveloper 10.1.3, and get the following error:
Element type "fault" is missing required attribute "name"
I have created a fault on one of the operations, and in the .wsdl file there is a name attribute:
<operation name="process">
<fault name="TestError" message="client:TestErrorMessage"/>
</operation>
The fault definition in the .wsdl obtained from the process when you access it over http is somewhat different:
<fault>
<soap:fault name="TestError" use="literal" encodingStyle="" />
</fault>
Any ideas how to workaround this problem?

Web service proxy take ~4 minutes to detect connection problem in AIX!

Dear All,
i am developing a client application that consume web service , by jdeveloper 10.1.3.1.
i found a problem, in AIX, that the web service proxy generated by jdeveloper take long time
to detect connection problem to the server (e.g. server is down, network down, invalid
ip address or port supplied).
in ms window, if the proxy can't reach the server, it throw exception within seconds.
but in ibm AIX, it take about 4 minutes !!! the time is too long until the exception is thrown.
could anybody help me?
is there something i can set to greatly shorten the hanging time when connection
problem?
thank you.

nobody experience this problem?

Test web service proxy using EJB session bean client...

Hello!
I am following this blog /people/abdelmorhit.elrhazi/blog/2009/10/30/how-to-consume-an-inbound-backend-web-service-in-nwdsjboss-environment to create a EJB session bean client to access the web service proxy...
The blog is not very clear. Where should I be deploying the web service proxy and the EJB session bean (web service client) ? on the PI 7.1 ?
How to find out the URL for the wsdl ?
Thanks

> The blog is not very clear. Where should I be deploying the web service proxy and the EJB session bean (web service client) ? on the PI 7.1 ?
"To deploy your web service proxy and session bean, right click on your JBoss server in the Servers view, and click on Add Remove Projects, add you ear file and click finish."
You need a JBoss server.

Web Service Proxy with Dynamic IP and Port

hi,
I am currently looking at the Web Service Proxy generation in JDev 11g. I can generate proxies fine, but the proxies are generated with static host and port. I want to substitute the host and port during runtime if required, for instance read the values from a database. I need to do this to avoid compiling the application for every deployment we make dev, test and production. Is there an easy way to set the generated proxy host and port? Are there any examples?
Thanks in advance!
Stephen

Hi,
Maybe you should have a look on XML Catalogs feature, but I am not sure if JDeveloper support it and how to support it.

Web service proxy receiving single element in array

I've generated a web service proxy over a web service and expect to get multiple elements returned from the web service. However when I excute the proxy I receive only the first element. Testing the web service with the same parameters on the application server shows that I should be receiving 3 elements in total. Not sure where the disconnect is in generating the response message within the proxy. Any suggestions is appreciated.

Are you looking for SOAP ENC Array feature? Which version are you using 10134 or 11g?
