How do I call a java method in JSTL?

Question

This may be a recurring question.

I just want to call a method that is not a getter or setter for example. makeCall (someObj, "stringvalue") of the xyz class.

Java class

Class XYZ{

    public String makeCall("someValue1","stringValue2"){

    //some logic here

    }
}

JSTL

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

Just create an object of the class with <jsp:useBean>

and call the method using the JavaServer Pages Standard Tag Library or Expression Language , which is easier to use and less error prone.

example code:

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

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

Try the following:

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

For this we need to create our own tag. (in .tld file)

and need to write one java class for this tag.

After that, you can call a method inside that native class and set the result to pageCotext to retrieve it to jsp.
