J2EEGetResult (Function)

In french: J2EEDonneRésultat

Returns the result of the last J2EE procedure that was successfully run.

Note: This procedure was run by J2EERun or J2EERunXML.

Example

// This example is based on the presence of Text2Image Webservice
// on the dwdemos.alphaworks.ibm.com site.
// If the module was no longer available on the site,
// the example would not operate anymore
// Interrogate the Webservice on the Web server
IF J2EERun(...
"http://dwdemos.alphaworks.ibm.com:8085/soap/servlet/rpcrouter", ...
"createImage", "urn:text2image", ...
"http://alphaworks.ibm.com/alphabeans/text2image/createImage/") THEN
// The result is an image, it will be changed into a temporary file
nFileID is int
nFileID = fOpen(fExeDir() + "\temp.gif", foCreate)
fWrite(nFileID, J2EEGetResult(J2EEResult))
fClose(nFileID)
// Display
IMG_GEN = ""
IMG_GEN = fExeDir() + "\temp.gif"
// Delete the temporary file
fDelete(IMG_GEN)
ELSE
// If the service returns no error (ex: Server not accessible)
IF J2EEError(J2EEErrMessage) ~= "" THEN
Error(ErrorInfo())
// If the service returned an error (service error)
ELSE
Error("J2EE error: " + J2EEError(J2EEErrMessage))
END
END

Syntax

<Result> = J2EEGetResult(<Type of Result> [, <Result Number>])

<Result>: Character string

Result of the last J2EE procedure successfully run.
If several results are returned by the server and if the J2EEResult constant is used:
result <Result Number>,
first result returned if <Result Number> is not specified.
An empty string ("") if:
no result was returned by the server,
no connection was established with the server.

<Type of Result>: Constant

Type of result to return:
J2EEResult Result of the last J2EE procedure run.
J2EEHTTPResult Result (in HTTP format) of the last J2EE procedure run.
J2EEXMLResult Result (in XML format) of the last J2EE procedure run.

<Result Number>: Optional integer

Number of the result to return. This parameter is used only if several results are returned by the server and if the J2EEResult constant is specified. Otherwise, this parameter is ignored.

Remarks

The different types of results

The same procedure run on a server can return three types of results.

Let's study the following example:
The "getTemp" procedure (used to find out the temperature of a city) has been run. The types of results returned by J2EEGetResult are as follows:

With the J2EEResult constant: 37
With the J2EEHTTPResult constant:
