Hi, I need to modify the layout of the AFP, so i download the file com.sap.portal.navigation.afp.layout, but when i import the proyect in the nwds 7.3, i have many errors with imports, many of whom could solve importing the respective jars but the are 3 that i could't solve:

com.sap.portal.navigation.jjs.JJSArray

com.sapportals.portal.pb.layout.taglib.variabledef.RunMode

prt:taglib:com.sap.portal.reserved.layout.TagLibLayout

Could someone tell me in whichs jars are?
