problem with <c:out> and fn:trim
Hi all
I have a problem using jstl functions
I have a tag file with following code
<%@ taglib uri="/WEB-INF/tlds/c-1_0-rt.tld" prefix="c_rt" %>
<%@ taglib uri="/WEB-INF/tlds/fn.tld" prefix="fn" %>
<%@ attribute name="path" required="true" %>
<%@ attribute name="base" required="false" %>
<c_rt:url value="/${path}" var="realPath" />
<c_rt:out value="${fn:trim(realPath)}" />
when I am using this tag file the output is ${fn.trim(realPath)} with no error or exception, it seems that c:url and c:out dont work !!!
but when I change the tld from c-1_0-rt.tld to c-1_0.tld the c:url and c:out work fine but I can't use fn:trim() because they dont accept expression values
what is wrong with my code?
both tld files are existing under the WEB-INF/tlds directory
in second state the following exception will be thrown:
org.apache.jasper.JasperException: <h3>Validation error messages from TagLibraryValidatorfor c</h3>
8: tag ='out' / attribute ='value': An error occurredwhile parsing custom action attribute"value" with value"${fn:trim(realPath)}": org.apache.taglibs.standard.lang.jstl.parser.ParseException: EL functions are not supported.
any help would be appreciated
