Hi,
I included the xsp-request namespace in my XSP and then put in the code: <xsp:logic> String productId = <xsp-request:get-parameter name="productid"/>; </xsp:logic> This code is right above my root document element. I get this error when I try running it by going to http://localhost:8080/cocoon/test?productid=12345678: org.apache.cocoon.ProcessingException: Language Exception: org.apache.cocoon.components.language.LanguageException: Error while instantiating org/apache/cocoon/www/products_xsp: java.lang.NullPointerException The product with productid 12345678 exists in my backend database and the code works fine when I hardcode the value into my XSP, rather than trying to get it as a parameter. Any idea what I'm doing wrong?
