Invoke a method dynamically

Question

Hi,
I want to invoke a method dynamically. I have the class name and method name in a variable and the list of import and export parameter for this method in an internal table. Now I need to invoke this method dynamically i.e. without having it to call in code like this classname->methodname(.....). I want something like reflection in java, where we can call the method using invoke method of method class ex:
try {
Method method = cls.getMethod( "setColor",
new Class[] {Color.class} );
method.invoke( obj, new Object[] );
It would be helpful if you can provide a simple example on how it can be implemented in ABAP.
Thanks,

Hi,
     You can perform calls in that way as follows.
You need to pass the parameters usingthe following table of type ABAP_PARAMBIND_TAB.
DATA: ptab type ABAP_PARAMBIND_TAB,
           ptab_line like line of ptab.
DATA: clas_name type stirng VALUE 'CLASS_NAME',
           method_name type string VALUE 'METHOD_NAME'.
DATA: obj  type ref to OBJECT.
create object obj type class_name.
ptab_line-name = 'PARAM_NAME'.
ptab_line-kind = CL_ABAP_OBJECTDESCR=>EXPORTING.
Then you can use
CALL METHOD  obj->(method_name) PARAMETER-TABLE ptab.
