ClassCastException while accessing PCD objects

[ankur_garg5]

Hi,

I am trying to access iViews and System objects from the Portal PCD using the code given in the following wiki link:

http://wiki.sdn.sap.com/wiki/display/WDJava/Retrieving+all+iViews+from+PCD

I am getting ClassCastException on the following line of code:

IPcdSearchResult searchResult = (IPcdSearchResult) ne.nextElement();

The complete exception is:

java.lang.ClassCastException: class com.sapportals.portal.pcd.gl.PcdGlSearchResult:service:com.sap.tc.pcd.gl.srv@com.sap.engine.boot.loader.ResourceMultiParentClassLoader@1e071f47@alive incompatible with interface com.sapportals.portal.pcd.gl.IPcdSearchResult:sap.com/home~mdm_framework@com.sap.engine.boot.loader.ResourceMultiParentClassLoader@6dcec96a@alive

I am doing this in NW7.3 Portal. This very code works fine in NW7.0. Please help me to resolve this error.

Thanks & Regards,

Hi Ankur,

Have you tried this:

list = initialContext.list(root);

NameClassPair nameClass;

while(list.hasMore()) {

nameClass = (NameClassPair) list.next();

if(nameClass

.getClassName()

.equals("com.sapportals.portal.ivs.iviews.IPortalIview"))

{ //do something }

if(nameClass

.getClassName()

.equals("com.sapportals.iviewserver.systemlandscape.service.ISystemObject"))

{ //do something }

}

Hi Ankur,

So it looks like the API has changed from 7.0 to 7.3... can you instead cast to the actual correct type (e.g. PcdGISearchResult)... the code here shows how to do this:

https://cw.sdn.sap.com/cw/sources/1199?view=file-source&path=trunk%2Fcom.sap.MobileServices%2Fsrc.co...

I can't find any public Javadocs for PcdGlSearchResult I'm afraid.

Hope this helps,
Simon
