Cannot cast java.io.serialiazable to int Error

Question

Dear Members,
I have procedure in AM which is as follows:
public int countRecs(String headerID)
int count=0;
count= integer value assigned from SQL Query*
return count;
I am calling this procedure from the CO of the page as follows:
String headerID="123"
int     count=0;
*Serialiazable para[]={headerID};*
count=(int)am.invokeMethod("countRecs",headerID);
When I am compiling my CO I am getting the below error:
Cannot cast java.io.serialiazable to int
Kindly please help me in resolving this error.
Many thanks in advance.

Answer 1

the signature of the method you are invoking is
public Serializable invokeMethod(String methodName,
Serializable[] methodParams)
so the return type is also serializable. so you should change your method signature accordingly
public int countRecs(String headerID)
int count=0;
count= integer value assigned from SQL Query*
return count;
public String countRecs(String headerID)
//just change last statement
return ""+count;}
your CO call should be
count=(int)am.invokeMethod("countRecs",headerID);count = Integer.parseInt(am.invokeMethod("countRecs",para));
so finally your count variable will hold an integer
you may need to keep the above statement in try catch block
