<logic:present name="lastName" scope="request">
<logic:equal name="submitForm" property="age" value="a">
<logic:equal name="submitForm" property="age" value="c">
<bean:write name="lastName" scope="request"/>

i was doing some jsp tutorials found online but they produced errors, so when i looked up the answers they were the as the codes question is

why is <logic:equal...> used and what does it mean? whats the difference between <logic:present...> and <logic:equal...> ?

lastly, wat does
<bean:write name="lastName" scope="request"/> do?

As you are aware, the tags you mentioned are all struts tags.
The tag <logic:present ..> is similar to the normal 'if' loop of java.

if property named lastname exists then enter the loop and do the rest.

similarly <logic:equal ...> ,meaning if the value of the property named 'age' is equal to value 'a' then do this or else do the rest.

and the struts tag <bean:write..> is used to display the output of the
form property value on the screen.

For more clear understanding ,better you go thru the struts HTML,LOGIC,BEAN tags and its libraries.

We have a forum devoted to Struts.
This is the best place to ask this question.
Moving this thread to the Struts forum.
