Problem instatiating factory implementation when invoking a service in java

Hello,
I' have the following problem: When I invoke a service from java code (it is a customized policy step implementation of a server agent), I get the following exception (some part of the error message description is german because it's a german versin of the SOA Suite, my translations are in []):

Hello,
I had to add the information, which jar-file has to be used, into the build.xml that is used by the ant script.
Now the missing class problem is solved, but now there is another (similar) problem:

Maybe "extraneous" is an incorrect term. Apparantly, based upon the writeup within Wiki, the parser I am using does not interpret the """? How do I find which parser is being utilized and how to control it?

Java exception when invoking web service

I am using JDeveloper 10.1.3.04 to deploy a PL/SQL function as a web service to 10gIAS. I can deploy the service, but when invoking it from the endpoint my SOAP output looks like this:
<?xml version="1.0" encoding="UTF-8" ?>
- <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
- <SOAP-ENV:Body>
- <SOAP-ENV:Fault>
<faultcode>SOAP-ENV:Server.Exception:</faultcode>
<faultstring>java.lang.NullPointerException</faultstring>
<faultactor>/GetAmountContextRoot/MyWebService1</faultactor>
</SOAP-ENV:Fault>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Deploying what is essentially the same web service to the OC4J instance that comes with JDeveloper, my SOAP returns the expected value:
<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns0="http://devl29ieda/MyWebService2.wsdl/types/"><env:Body><ns0:returnAmountResponseElement><ns0:result>305249</ns0:result></ns0:returnAmountResponseElement></env:Body></env:Envelope>
I believe the problem is within the Java code created by the Web Service Wizard, but I do not know where.
Any help would be greatly appreciated.
Steven

Hi Steven,
You may want to look at the log on the server side to see if you have any hint that may help you track down where the NPE is comming from.
As you are using PL/SQL function, the other think you want to check is that the datasource information are properly defined in both environment.
Hope it helps,

Proxy Error When Invoking Web Service

Hi all,
i created a web service from a session bean,
when i invoke the web service from my web browser it works great,
but when i try to invoke it from a bpel process, i get the following error in the Invoke Activity:
when invoking endpointAddress 'http://10.0.1.159:8989/EJB-Application2-Model-context-root/updatePayloadServiceSoapHttpPort', (502)Proxy Error ( The ISA Server denied the specified Uniform Resource Locator (URL). )
any idea what to do to resolve this issue?
thanks

It seems that your proxy server refuses serve requests for your private network (10.0.x.x).
Try to turn off proxy server in your BPEL. In devel server turn off proxy (or add this address to exceptions) in <ORAHOME>\integration\orabpel\bin\obsetenv.bat
and if you are using full AS, go to EM a change parameters for these server properties:
-Dhttp.proxySet=true
-Dhttp.proxyHost=yourproxy
-Dhttp.proxyPort=proxyport
-Dhttp.nonProxyHosts=10.0.1.159|and rest of your exceptions

Passing Username and Password When Invoking Another Service

Suppose that I have Service A that calls Service B in its code.
I can set authentication , inbound/outbound integrity and confidentiality settings for this service.(Service A)
Can I define a mechanism-declaratively-that tell the service A to include this information (username and password) in its SOAP request message when calling another service? (service B, suppose that service B's authentication is enabled) for example in WS-Security part of the request to service B.
Best Regards,
Farbod

It appears the only way to parameterize the Applications username and password in Web forms is to use either
a cartridge implementation or javascript. I found the following document on Metalink describing the
javascript solution:

Connection Reset Error, When invoking Web Services

I'm trying to invoke a web service using 'Invoke Web Service' Operation. Its works for 8 out of 10 times. Sometime it stalled with "Conneciton Reset' error.
When retry this stalled action from AdminUI, its works fine.
Can someone advise on this issue?
I have attached the error log for reference.
Thanks,
Nith

If you attempt to retry the stalled component through adminui, it will work. Am i correct?
If so, you can test the following approach.
1. drag a blank component (e.g a decision point)
2. connect a line between the exception of the Web Service Invoke operation to the decision point.
3. Choose java.io.IOException from the eeception drop down.
4. again connect the decision point back to the web service invoke component. (i mean a looping)
This approach was working fine with me.
Please see the attached image shows my routing.
PS: After a couple of days, I tested without looping and it seems to be working. So I removed the loop now.
Thanks,
Nith

Error invoking Web Service from Java client

Hi
I have created an ALSB Proxy service and exposed it as a web service. I have created a Java Client the code for which is pasted below:
     String ENCODING_STYLE_PROPERTY = "javax.xml.rpc.encodingstyle.namespace.uri";
     String URI_ENCODING = "http://schemas.xmlsoap.org/soap/encoding/";
     String url = "http://localhost:7001/Dummy_ALSB_Project/proxy/Dummy_Proxy_Service?WSDL";
     String TARGET_NAMESPACE = "http://www.bea.com/servers/wls810/samples/examples/webservices/handler/log";
     QName xsdString = new QName("http://www.w3.org/2001/XMLSchema", "string");
     ServiceFactory factory = ServiceFactory.newInstance();
     QName serviceName = new QName(TARGET_NAMESPACE, "LogHandler");
     QName portName = new QName(TARGET_NAMESPACE, "ProcessSoap");
     QName operationName = new QName("writeCustNameToFile");
     Service service = factory.createService(serviceName);
     Call call = service.createCall();
     call.setPortTypeName(portName);
     call.setOperationName(operationName);
     call.addParameter("param0", xsdString, ParameterMode.IN);
     call.setProperty(ENCODING_STYLE_PROPERTY,URI_ENCODING);
     call.setProperty(Call.SOAPACTION_USE_PROPERTY, new Boolean(true));
     call.setProperty(Call.SOAPACTION_URI_PROPERTY,"");
     //set end point address
     call.setTargetEndpointAddress(url);
     call.invoke(new Object[]{ "The Joshua Tree" });
When I run the service, I get the following error:
java.rmi.RemoteException: BEA-380001: Internal Server Error

     at TC.methodB(TC.java:67)

Any clues about what is going wrong?? Thanks in advance.

It's recommended to use the same verison of client and service.

Problem when invoke Web Service.

Hi all.
I have an interface that receive an IDoc and map it against a Web Services. In SXMB_MONI there is only one record and segment occurrence in XML is 0...1
In Receiver system's log figure that the web services was invoked too many times by XI.
Any Idea about it?
Thanks & Regards.
RP

Hi,
May be it is because of the ReTry attempt from the integration engine to deliver the messages,,
Check out the RWB>Message Monitoring>Message Display tool to do the analysis..
How many messages are there in the SXMB_MONI ? I don't think so, it is because of occurence of the data.. check the message mapping...

Return NULL when invoke Web Service via UTL_DBWS

Hi all,
right now, i'm using UTL_DBWS to acces Web Service via database.. but when i'm trying to get data from WEB SERVICE, using utl_dbws.invoke , i got NULL value.
It happened if The result more than Varchar2 / 32767 byte.
i'have tried to change code by :
result := sys.utl_dbws.invoke(l_call, l_input_params);
P_clob := sys.anydata.accessCLOB(result);
The Output IS NULL value even if the data was less than Varchar2 or 32767 byte..
this is my script looks like ::
declare
service sys.utl_dbws.SERVICE;
l_call sys.utl_dbws.CALL;
result ANYDATA;
wsdl_url VARCHAR2(1024);
service_name VARCHAR2(200);
operation_name VARCHAR2(200);
input_params sys.utl_dbws.ANYDATA_LIST;
p_out VARCHAR2(32767);
p_xml XMLTYPE;
p_clob CLOB;
begin
wsdl_url := 'http://127.0.0.1/Exercise/WSDL2.php?wsdl';
service_name :='{urn:hellowsdl}hellwsdl';
operation_name := 'getData';
service := sys.UTL_DBWS.create_service (
wsdl_document_location => URIFACTORY.getURI(wsdl_url),
service_name => service_name);
l_call := sys.utl_dbws.create_call(
service_handle => service,
port_name => null,
operation_name => operation_name
input_params(1) := ANYDATA.ConvertVarchar2('DOCCODE');
result := sys.utl_dbws.invoke(l_call, l_input_params);
p_out := sys.anydata.accessVarchar2(result);
sys.UTL_DBWS.release_call (call_handle => l_call);
sys.UTL_DBWS.release_service (service_handle => service);
end;
Thanx for Any Help

The basics are simple:
- format a valid SOAP envelope
- use UTL_HTTP to make the call
- process the response (typically XML output)

Java.sql.SQLException: Closed Connection error when invoking web service

Hi
I've assembled a simple web service for an Oracle PL/SQL package and deployed it on a Standalone OC4J, when I come to invoke it on the Oracle Enterprise Manager screen I'm getting the following returned within the envelope body:
<env:Body>
<env:Fault>
<faultcode>env:Server</faultcode>
<faultstring>Internal Server Error (serialization error: java.sql.SQLException: java.sql.SQLException: Closed Connection)</faultstring>
</env:Fault>
</env:Body>
The function that is called within the database returns a user defined object that consists of a RAW value and an XMLTYPE. The function takes a string as a parameter, when I enter a string that I know will not return an object there is no error in the envelope body, only when there is an object to return does the error appear.
Anyone have any suggestion as to why this is?

I'm no further forward with this: has anyone assembled, deployed and invoked a web service that returns a XMLTYPE?? I know this should be possible but I think there's maybe some manual intervention required with the classes created with webservicesassembler: I'd really appreciate it if anyone with any experience of this kind of thing could help me think this through.

Transaction Output when invoked Web Service

Hi all,
I have developed a transaction which has an output parameter of type list, derived from the classic ERP BAPI Flight Get List
When I invoke the transaction as web service from a SOAP test tool I get a SOAP response like:
<MyTestOutput>
[[string:FRA], [string:TYO], [string:FCO], [string:KIX]]
</MyTestOutput>
So the output xml element is just one, containing the whole list.
I don't like this because the web service consumer must parse that element to get all the result items.
What I would like is a more xml-like output structure, such as:
<MyTestOutput>[string:FRA]</MyTestOutput>
<MyTestOutput>[string:TYO]</MyTestOutput>
<MyTestOutput>[string:FCO]</MyTestOutput>
<MyTestOutput>[string:KIX]</MyTestOutput>
Is there a simple way to achieve that?
In the help/guides I have studied there's no hint about how to do so.
Thanks, regards
Vincenzo

Hi Vincenzo,
I reopened your thread.
Instead of making your output parameter type of List, create an output parameter of type xml. If you look at most of the transactions available as downloads, you will see numerous examples of the types of structures the xml will accomodate. And you will not have to convert the outputs back to xml for further processing.
If you use a repeater to build your xml, you can accomplish the structure you desire. Alternatively, you can build an MII Document and the format will be
<Rowsets>
<Rowset>
<Row>
<your Fieldname>
data1
</your Fieldname>
</Row>
<Row>
<your Fieldname>
data2
</your Fieldname>
</Row>
<Row>
<your Fieldname>
data3
</your Fieldname>
</Row>
<Row>
<your Fieldname>
data4
</your Fieldname>
</Row>
</Rowset>
</Rowsets>
Regards,
Mike

Problem with special characters when calling web services via ISG

Hi all,
I have a problem when trying to send or retrieve strings containing some special characters via Integrated SOA Gateway.
For example, when I call a PL/SQL function via ISG that returns a string containing curling single and double quote characters, these are not represented by valid XML character entity references. So when trying to open the response XML (returned by ISG) in a browser, I get a parser error...
Has anybody had a similar experience with ISG? How can I resolve that - is it an ISG bug?
Thanks

Error when invoking Rule Engine using Java API

Hi,
I have implemented a Java class which calls the Rule Engine to execute the rules. If I test by setting the value of the input inside a main method and get the output, it is working fine. The ruleset is also invoked and there is no problem. However, when I expose this java class as a web service and invoke the web service, I get the below error. I dont get the error if the .rules file is not present in the loaction mentioned. I get the error when the .rules file is present in the location. Not sure if this is an issue with the java call outs or loading the dictionary.
Error:_

The Java class looks like:
public PersonType Query (PersonType p)
try {
//FileReader reader = new FileReader("/home/orasoa/223345/STRS1.rules");
//FileReader reader = new FileReader("D:\\Arun\\NGCE_WS\\POC1\\UHG\\QueryStudentCriteria\\oracle\\rules\\querystudentcriteria\\STRS1.rules");
InputStream stream=ImplementRules.class.getResourceAsStream("/STRS1.rules");
Reader reader=new InputStreamReader(stream);
RuleDictionary dict = RuleDictionary.readDictionary(reader, new DecisionPointDictionaryFinder(null));
List<SDKWarning> warnings = new ArrayList<SDKWarning>();
dict.update(warnings);
DecisionPoint decisionPoint = new DecisionPointBuilder().with("STRS1_DecisionService_1").with(dict).build();
DecisionPointInstance point = decisionPoint.getInstance();
ArrayList input=new ArrayList();
input.add(p);
point.setInputs(input);
List<Object> output=point.invoke();
catch (Exception e) {}
return p;

Hi, I am getting a similar error when I deploy my application on the weblogic server.
Could you detail how this was resolved?
Thanks,
