J2EEGetResult (Function)

In french: J2EEDonneRésultat

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

Note This procedure was carried out by function J2EERun or J2EERunXML.

Example

// Cet exemple est basé sur la présence du module Text2Image Webservice
// sur le site dwdemos.alphaworks.ibm.com. 
// Si le module n'était plus disponible sur le site, 
// l'exemple ne fonctionnerait plus
// Interrogation du Webservice sur le serveur Web
IF J2EERun(...
	"http://dwdemos.alphaworks.ibm.com:8085/soap/servlet/rpcrouter", ...
	"createImage", "urn:text2image", ...
	"http://alphaworks.ibm.com/alphabeans/text2image/createImage/") THEN
	// Le résultat est une image, on en fait un fichier temporaire
	nIDFic is int
	nIDFic = fOpen(fExeDir() + "\temp.gif", foCreate)
	fWrite(nIDFic, J2EEGetResult(J2EEResult))
	fClose(nIDFic)
	// Affichage
	IMG_GEN = ""
	IMG_GEN = fExeDir() + "\temp.gif"
	// Suppression du fichier temporaire
	fDelete(IMG_GEN)
ELSE
	// Si le service ne retourne pas d'erreur (ex : Serveur inaccessible)
	IF J2EEError(J2EEErrMessage) ~= "" THEN
		Error(ErrorInfo()) 
		// Si le service a retourné une erreur (erreur du service)
	ELSE
		Error("Erreur J2EE : " + 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:
J2EEHTTPResult Result (in HTTP format) of the last J2EE procedure run.
J2EEResult Result 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.

Consider 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 constant J2EERresult: 37
With the J2EEHTTPResult constant:
