Scriplets in Liferay

Question

What can I do with this scriptlet

<%
    ResultRow row = (ResultRow) request.getAttribute(BookAndAuthor.SEARCH_CONTAINER_RESULT_ROW);

    Book book = (Book) row.getObject();
%>

If I want to use value="${book.BookId} in this code?

<liferay-ui:icon-menu>

     <portlet:actionURL name="deleteBook" var="deleteBookVar">
         <portlet:param name="bookId"     value="<%=String.valueOf(book.getBookId())%>" />
     </portlet:actionURL>

</liferay-ui:icon-menu>

@ParkashKumar I can't use scriplets in my project at all, it's task rule. I know that I can use JSTL and EL somehow, but I don't know how. :( — Al.Boldyrev, Sep 07 '16 at 12:38
You can first use JSTL to set these values using `c:set` then, use these with variable names using EL. — Parkash Kumar, Sep 07 '16 at 12:45

Sorry, it doesn't work. I know I should use c:set, but another way. :( — Al.Boldyrev, Sep 07 '16 at 14:16
I inserted you code instead of my scriplet and then use ${row.BookId} — Al.Boldyrev, Sep 07 '16 at 14:25

This is a little tricky but I thing it should work. Use a variable to hold the value of the constant SEARCH_CONTAINER‌_RESULT‌_ROW

<c:set var="resultRowConstant" value="<%=BookAndAuthor.SEARCH_CONTAINER‌_RESULT‌_ROW%>" /> than to read the attribute you you should be able to use bracket notation to access 'dynamic' properties: <c:set var="row" value="${[resultRowConstant]}"/> and that will hold the ResultRow object, than you access your book object through

${row.object}

No, it doesn't work. SEARCH_CONTAINER‌_RESULT‌_ROW is underlined and `Syntax error on tokens, delete these tokens` message. – Al.Boldyrev Sep 07 '16 at 17:12
So? I don't understand, sorry – Al.Boldyrev Sep 07 '16 at 17:30
You have to import the BookAndAuthor class to use it, like you do in java classes – KlajdPaja Sep 07 '16 at 17:34
Of course I have already imported my class. So this problem is somewhere else. – Al.Boldyrev Sep 07 '16 at 18:08
