Integrate WebDynpro with XI using SOAP

[Former Member]

Hi,

I am one of the SDN members. I am trying to integrate WebDynpro with XI using SOAP. There is an object in XI, which I am trying to access through WebDynpro using SOAP.

However I am facing some problems on this. When I am trying to access the XI object through my WebDynpro application I am getting a "401 error" which means that object is not found. But when I try to access the object through the browser (using the link from the wsdl file) it first asks for a username and password and then I am able to access the object.

I have no clue why this is happening. I have tried a lot of thing but nothing seems to be working.

Is it because I am not passing the username and password in my code I am not able to access the object or is the way I am establishing the connection is incorrect ? Anyone please advice. I am enclosing a copy of my code (the action method which does all this). Let me know your thoughts on the code.

Eagerly awaiting your reply.

The code is as follows:

public void onActionSendSOAPMessage(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )

{

//@@begin onActionSendSOAPMessage(ServerEvent)

String SOAPXML = "<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">"

+ "<soap:Body>"

+ "<getProductDetails xmlns=\"http://warehouse.example.com/ws\">"

+ "<productID>827635122</productID>"

+ "</getProductDetails>"

+ "</soap:Body>"

+ "</soap:Envelope>";

try{

String StringURL = "This is where I placed the link";

URL url= new URL(StringURL);

// Create HTTP Connection

HttpURLConnection connection = (HttpURLConnection)url.openConnection();

connection.setDoInput(true);

connection.setDoOutput(true);

connection.setUseCaches(true);

connection.setRequestMethod("POST");

connection.connect();

// Done Creating HTTP Connection

// Write to XI

OutputStreamWriter out = new OutputStreamWriter (connection.getOutputStream());

out.write(SOAPXML);

out.flush();

out.close();

// Done Writing to XI

// Read Response from XI

BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));

String XIResponse = "";

String XMLfromXI = "";//This is the string for storing the concatenated response from XI

while((XIResponse = in.readLine()) != null )

{

XMLfromXI += XIResponse;

}

//

IWDConfirmationDialog dialog4 = wdComponentAPI.getWindowManager().createConfirmationWindow

(XMLfromXI,wdControllerAPI.getControllerInfo().findInEventHandlers("OnEventNO"),"OK");

dialog4.open();

}catch (Exception e){

e.getLocalizedMessage();

IWDConfirmationDialog dialog33 = wdComponentAPI.getWindowManager().createConfirmationWindow

("Connection Error : "

+e.getLocalizedMessage(),wdControllerAPI.getControllerInfo().findInEventHandlers("OnEventNO"),"OK");

dialog33.open();

}

//@@end

}

Hi ,

Try appending the userid and password in the StringURL which you already have which could avoid authorization failure.

Hi!!!

Sending user name and password as parameters in an url is not a good idea.

Could you try this:

(...)

// Create HTTP Connection

HttpURLConnection connection = (HttpURLConnection)url.openConnection();

// new code

String userName = "officeboy";

String password = "secret";

String userPasswd = userName + ":" + password;

String encoding = new sun.misc.BASE64Encoder().encode(userPasswd.getBytes());

connection.setRequestProperty("Authorization", "Basic " + encoding);

// end of new code

connection.setDoInput(true);

connection.setDoOutput(true);

(...)

Of course, change values for userName and password variables.

Regards,

Andrzej

Hi,

>>>a "401 error" which means that object is not found.
