I have a code in JSP as follows
<td class=odd
style="text-align: center"
height=30><c:if
test="${mMap['GENERAL'].errorFac != 0 and not empty mMap['GENERAL'].errorFac}">
<c:choose>
<c:when test="${mMap['GENERAL'].errorFlag == true}">
<A style="font-size:9pt" href="javascript:openWindow('${m.eTax}','${m.eDate}','GENERAL')" >
<fmt:formatNumber
value="${mMap['GENERAL'].errorFac}"
type="number" pattern="#,##0.0000" /></A>
</c:when>
<c:otherwise>
<fmt:formatNumber
value="${mMap['GENERAL'].errorFac}"
type="number" pattern="#,##0.0000" />
</c:otherwise>
</c:choose>
</c:if>
</td>
When the jsp is called I am getting foll. error in console:
[5/3/17 10:13:14:025 EDT] 00000253 SystemErr R Caused by: javax.el.ELException: Cannot convert 2.34 of type class java.lang.String to class java.lang.Long

Value 2.34 is the value of errorFac which come as a path variable and is a String. I am assuming the c:if is causing the issue. Any inputs please.
Based on this post
you need compare String to String and zero is an Integer, so:
<c:if test="${mMap['GENERAL'].errorFac != '0' and not empty mMap['GENERAL'].errorFac}">
