Getting JspCoreException while using EL

[Aarav Thomas]

Hi,

I'm trying to get the JSP file name in my custom tag. So, i'm using the following code to achieve it.

<common:printFileName fileName="<c:out value="${pageContext.request.requestURI}"/>"/>

But i'm getting the following error:

[Servlet Error]-[/WEB-INF/pages/auth/Signon.jsp]: com.ibm.ws.jsp.JspCoreException: /WEB-INF/pages/auth/Signon.jsp(29,83) JSPG0055E: Unable to create an xml attribute from name [${pageContext.request.requestURI}] value [/>]

But when i try to print the file name as follows, then it prints the file name correctly:

<tr><td><c:out value="${pageContext.request.requestURI}"/> </td></tr>

Can some please explain what is wrong in the below code? Any help in this regard would be much appreciated.

<common:printFileName fileName="<c:out value="${pageContext.request.requestURI}"/>"/>

(There seems to be no issues with my custom tag, because when i put some random literal string in place of

<c:out value="${pageContext.request.requestURI}"/> 

then my tag works fine.)

Also please note in the custom tag; "pageContext.getRequest()" gives me an instance of ServletRequest; so i can not use "pageContext.getRequest().getRequestURI()" in my custom tag.

You can't use a custom tag as the attribute value of a custom tag. Why are you using <c:out> at all? Just use the EL expression.
