How to call java method in JSTL? [duplicate]

Question

This might be duplicate question.

I just want to call method which is not getter or setter method eg. makeCall(someObj,"stringvalue") of xyz class.

Java Class

Class XYZ{

    public String makeCall(Object objValue, String stringValue){

    //some logic here

    }
}

JSTL

<jsp:userBean id="xyz" class="com.XYZ"/>
${xyz.makeCall("hello","Friend")}

Answer 1

Simply create an object of the class using <jsp:useBean> and call the method using JavaServer Pages Standard Tag Library or Expression Language that is more easy to use and less error prone.

sample code:

<jsp:useBean id="test" class="com.x.y.z.XYZ"/>

${test.methodXYZ(object,"myString")}

Answer 2

Try with this:

<c:out value="${XYZbean.makeCall(someObjBean, 'value')}" />
