Linking two webdynpro application

Hi ED,

a little bit more low level call of another WD url is done by the following code snippet:

//@@begin onActionRedirect(ServerEvent)

// Application is in the deployable object of the caller component in this case.

IWDDeployableObject componentDPO =

wdComponentAPI.getDeployableObjectPart().getDeployableObject();

String appName = "RedirApp";

WDDeployableObjectPart[] applicationParts =

componentDPO.getParts(WDDeployableObjectPartType.APPLICATION);

if (applicationParts == null || applicationParts.length == 0) {

throw new WDRuntimeException(

"Redirect error: No application parts available in: " + componentDPO.getName());

}

WDDeployableObjectPart appPart = null;

for (int idx = 0; idx < applicationParts.length; idx++) {

appPart = applicationParts[idx];

if (appPart.getShortName().equals(appName)) {

break;

}

appPart = null;

}

if (appPart == null) {

throw new WDRuntimeException(

"Redirect error: The application: "

+ appName

+ " is not a part of: "

+ componentDPO.getName());

}

Map urlParameters = new HashMap();

urlParameters.put(ClientConstants.APPLICATION_PREFIX + "Param1", "Parameter sent by caller.");

try {

String url = WDURLGenerator.getApplicationURL(appPart, urlParameters);

if (!Task

.getCurrentTask()

.getClient()

.sendRedirect(url, ClientConstants.SESSION_EXPIRED_REDIRECT_TYPE)) {

throw new WDRuntimeException(

"Redirect to application: "

+ appName

+ " in dpo: "

+ componentDPO.getName()

+ " failed.");

}

} catch (WDURLException e) {

throw new WDRuntimeException(e);

} catch (IOException e) {

throw new WDRuntimeException(e);

}

//@@end

Then, somewhere in the called app, you can receive the parameter of the sample by:

String param1 =

Task.getCurrentTask().getWebContextAdapter().getRequestParameter(

ClientConstants.APPLICATION_PREFIX + "Param1");

But beware! I'm not really sure, if this is really a "legal" way of calling another application.

Hope that helps.

Regards

Stefan
