Problem in executing/invoking webservice

[Former Member]

<b>Hi All,

I'm trying to invoke a webservice through following code in component controller :</b>

public void getCategoryBapi( )

{

//@@begin getCategoryBapi()

try

{

logger.errorT("INSIDE getCategoryBapi() method...");

wdContext.currentRequest_Z_WS_CATEGORIES_GETLIST_zbapiCategoriesGetlistElement().modelObject().execute();

logger.errorT("WEB SERVICE INVOKED....");

wdContext.nodeResponse_category().invalidate();

wdContext.nodeResult_category().invalidate();

wdContext.nodeZcategDetails_category().invalidate();

IWDAttributeInfo category;

ISimpleTypeModifiable decision;

IModifiableSimpleValueSet valueSetDecision;

category = wdContext.nodeCatNode().getNodeInfo().getAttribute(IPrivateExternalView.ICatNodeElement.CAT_VALUE);

decision = category.getModifiableSimpleType();

valueSetDecision = decision.getSVServices().getModifiableSimpleValueSet();

// Access the proxy and get all available locations

// loop over the result list

for(int i=0;i<wdContext.nodeZcategDetails_category().size();i++)

{

logger.errorT("CATID: " + wdContext.nodeZcategDetails_category().getZcategDetails_categoryElementAt(i).getCatid());

logger.errorT("CAT DESC: " + wdContext.nodeZcategDetails_category().getZcategDetails_categoryElementAt(i).getCatname());

valueSetDecision.put(

wdContext.nodeZcategDetails_category().getZcategDetails_categoryElementAt(i).getCatid(),

wdContext.nodeZcategDetails_category().getZcategDetails_categoryElementAt(i).getCatname());

}

}

catch(Exception e)

{

logger.errorT(e.toString());

}

//@@end

Hi Ranjan,

First check weather the attribute exists in the webservice ot not.

2. Request_Z_WS_CATEGORIES_GETLIST_zbapiCategoriesGetlist input = new Request_Z_WS_CATEGORIES_GETLIST_zbapiCategoriesGetlist();

<B>input.setZcategDetails("XXX"); </B>

Hi Ranjan,

You need to set the value for the attribute "[ZcategDetails]".

Set the above property in your code and try.

Anilkumar,

Actually, I've already set that value in the wddoinit() as shown below. Could you explain further what you mean by "attribute [ZcategDetails]"? If you have any other suggestions, I would really appreciate it.

Thanks,

Ranjan

Request_Z_WS_CATEGORIES_GETLIST_zbapiCategoriesGetlist input = new Request_Z_WS_CATEGORIES_GETLIST_zbapiCategoriesGetlist(); wdContext.nodeRequest_Z_WS_CATEGORIES_GETLIST_zbapiCategoriesGetlist().bind(input); ComplexType_ZbapiCategoriesGetlist comCatgetList = new ComplexType_ZbapiCategoriesGetlist(); comCatgetList.setClassgroup("BAMS"); this.getCategoryBapi(); logger.errorT("CALLEDT");
