Title: problem with beans

Hi.

 

obj is not initialised in testBean. Try something like:

 

private xyz.xyzBean obj = new xyz.xyzBean();

gnujsp/Ann,

my beans:

package test;
class testBean
{
        private xyz.xyzBean obj;
        public String methodA
        {
              return "hello";
        }

        public String methodB
        {
              String b=obj.methodX();
              return b;
        }
             
        public String methodC
        {
              String c=obj.methodY();
              return c;
        }

}

package xyz
class .xyzBean
{

        public String methodX
        {
              return "hello from xyzBean";
        }

        public String methodY
        {
              //String value returned is retrieved from the database all within this method.

        }

}

above beans are complied from  mybean directorey

repositories settings :
repositories=E:\gnujsp-1.0.1\mybean

-classpath settings:
servlet.gnujsp.initArgs=compiler=builtin-javac -classpath "%classpath%;%scratchdir%;E:\gnujsp-1.0.1\lib\gnujsp10.jar;E:\gnujsp-1.0.1\mybean" -d "%scratchdir%" -deprecation "%source%"

my jsp:

<jsp:useBean id="obj" class="test.testBean"/>
<%

String str=obj.methodA();
out.println(str);
//working
//but
String str=obj.methodB();
out.println(str);
//Does not work

//Null Pointer Exception raised

//also
String str=obj.methodC();
out.println(str);
//Does not work
//Null Pointer Exception raised
%>

an early replay will be appreciated
