我试图使用pagestep函数，在单个JSP页面中使用多个函数。为实现这一目标，我使用的是JSTL。这是代码：
<c:if test="${pageStep.equals('init') || pageStep.equals('search') || pageStep.equals('createSubmit') || pageStep.equals('delete') || pageStep.equals('editSubmit')}">
在这段代码中，我收到了一个错误。堆栈如下：
com.ibm.ws.jsp.translator.JspTranslationException: JSPG0227E: Exception caught while translating /secure/systemparameters/UploadTransData/uploadTransData.jsp:
/secure/systemparameters/UploadTransData/uploadTransData.jsp(38,2) --> JSPG0122E: Unable to parse EL function ${pageStep.equals('init') || pageStep.equals('search') || pageStep.equals('createSubmit') || pageStep.equals('delete') || pageStep.equals('editSubmit')}.

我不允许升级到Websphere 8.我必须坚持使用Websphere 7.此代码在Tomcat和Weblogic中运行时没有任何问题。
我似乎无法对此问题进行排序。帮助将不胜感激。

Java EE 6（WAS v8）支持使用EL中的参数调用方法。在WAS v7中，您需要以下语法：
<c:if test="${pageStep eq 'init' || pageStep eq 'search'
|| pageStep eq 'createSubmit' || pageStep eq 'delete'
|| pageStep eq 'editSubmit'}">
