Hello John,
You can use reflection to invoke methods. Take a look at this class:
java.lang.reflect.Method. There are plenty of tutorials on how to use this
class to dynamically invoke methods.
Regards,
Ted

Subject: [cinjug-users] Access of anonomuos bean paramters inside JSTL or Cust.
Tag
Ladies and Gentlemen;
I have a requirement to develope a custom tag that will have passed to it a
collection of
beans, object type unknown, and render the bean fields as a header in an html
table and the
bean parameters in the rest of the table. This tag would have many
oppertunities for use
throughout the application, hence the desire to write the code in a reuseable
class.
Of coarse , this is trivial in JSTL if I know the bean object type in the
collection that is
passed, but not knowing the object type certainly makes it more challenging.
Clearly, reflection would be involved to get the parameters and the field
names, but, If I
can't cast the object being retrieved from the collection, I don't think using
reflection on a
generic Object instance is going to help me.
Any ideas are appreciated.
Thank You;
John Olmstead
