How can I use java variable in jsp tag in .jsp file?

Question

I am trying to use the value of a java variable in a jsp tag. Currently, I am trying like this.

<%
String searchRowCount = request.getSession().getAttribute("rowCount").toString();
%>
<br/>
<fmt:message key="SEARCH_UPDATE.ITEM_FOUND_MESSAGE" var="ITEM_FOUND_MESSAGE">
<fmt:param value="<%=searchRowCount%>"/>
</fmt:message>

But It is not working.

Thanks for the help.

the best way is: not. you should keep business logic (java code) in the servlets — Stultuske, Apr 23 '19 at 11:09

You can use Expression Language or JSTL

Using expression language:

<%
  String searchRowCount = request.getSession().getAttribute("rowCount").toString();
%> 

<fmt:message key="SEARCH_UPDATE.ITEM_FOUND_MESSAGE" var="ITEM_FOUND_MESSAGE">
    <fmt:param value="${searchRowCount}"/>
</fmt:message>

You can use sessionScope object like this.

  <fmt:message key="SEARCH_UPDATE.ITEM_FOUND_MESSAGE" var="ITEM_FOUND_MESSAGE">
        <fmt:param value="${sessionScope.rowCount}"/>
    </fmt:message>
