about jstl in tomcat!

this is my some cod in my project:
<jsp:useBean id="idCommunity" class="com.beltino.communitymedical.community.Community" scope="page" />

<c:set var="id" value="${param.id}"/>
<c:set var="action" value="${param.action}"/>
<c:set var="retList"/>
<c:if test="${empty id}">
<c:set var="action" value="new"/>
</c:if>
<c:if test="${!empty id}">
<c:set var="action" value="edit"/>
<c:set var="idCommunity" value="${idCommunity.getCommunityInformation(id)}"/> //有问题
<c:set var="retList" value="${idCommunity.getCommunityChildByPId(id)}"/>
</c:if>
........
now <c:set var="idCommunity" value="${idCommunity.getCommunityInformation(id)}"/> is error,and the error message is:
org.apache.jasper.JasperException: /webapp/community/editCommunity.jsp(24,3) The function getCommunityInformation must be used with a prefix when a default namespace is not specified

but when i use this page in resin3.0.8 ,it can work well ,but when in tomcat5.0.28,it can not work!

I don't think you can call methods with parameters in JSTL. Tomcat is confusing the method call with the JSP 2.0 feature of functions. You need to call using the following syntax:
${prefix:methodName(param1, param2, ...)}
and also include the TLD

<function>
<name>methodName</name>
<function-class>className</function-class>
<function-signature>
returnType methodName(param1Type, param2Type, ...)
</function-signature>
</function>

See this tutorial:

Tomcat is closer to the standard so my guess is that you are using a feature that is specific to resin. If you use the JSTL functions they should work in Resin.
