java – JSPG0122E：无法解析Websphere 8中的EL函数

我正在将Web应用程序从Websphere 6.1移动到Websphere 8,我在其中一个JSP页面中遇到以下错误：

com.ibm.ws.jsp.translator.JspTranslationException: JSPG0227E: Exception caught while translating /jsp/myJsp.jsp: /jsp/myJsp.jsp(863,4) –> JSPG0122E: Unable to parse EL function ${not empty rowVo.operation.package}. at com.ibm.ws.jsp.translator.visitor.validator.ELValidator.validateElFunction(ELValidator.java:500) at com.ibm.ws.jsp.translator.visitor.validator.ELValidator.validateELExpression(ELValidator.java:122) at com.ibm.ws.jsp.translator.visitor.validator.ELValidator.validateELExpression(ELValidator.java:149) at com.ibm.ws.jsp.translator.visitor.validator.ValidateVisitor.validateCustomTagAttribute(ValidateVisitor.java:1757) at com.ibm.ws.jsp.translator.visitor.validator.ValidateVisitor.validateCustomTagAttributeValues(ValidateVisitor.java:1405) at com.ibm.ws.jsp.translator.visitor.validator.ValidateVisitor.visitCustomTagStart(ValidateVisitor.java:294) at com.ibm.ws.jsp.translator.visitor.JspVisitor.processJspElement(JspVisitor.java:366) at com.ibm.ws.jsp.translator.visitor.JspVisitor.processChildren(JspVisitor.java:419) at com.ibm.ws.jsp.translator.visitor.JspVisitor.processJspElement(JspVisitor.java:369) at com.ibm.ws.jsp.translator.visitor.JspVisitor.processChildren(JspVisitor.java:419) at com.ibm.ws.jsp.translator.visitor.JspVisitor.processJspElement(JspVisitor.java:369) at com.ibm.ws.jsp.translator.visitor.JspVisitor.processChildren(JspVisitor.java:419) at com.ibm.ws.jsp.translator.visitor.JspVisitor.processJspElement(JspVisitor.java:234) at com.ibm.ws.jsp.translator.visitor.JspVisitor.visit(JspVisitor.java:216) at com.ibm.ws.jsp.translator.JspTranslator.processVisitors(JspTranslator.java:127) at com.ibm.ws.jsp.translator.utils.JspTranslatorUtil.translateJsp(JspTranslatorUtil.java:254) at com.ibm.ws.jsp.translator.utils.JspTranslatorUtil.translateJspAndCompile(JspTranslatorUtil.java:121)

JSP文件中的违规部分如下所示：

<c:forEach var="rowVo"
  items="${searchResultContainer.searchResultRowsPage}"
  varStatus="opStatus">
    <c:if test="${not empty rowVo.operation.jobscopeDescription}">
        <td>${rowVo.operation.jobscopeDescription}</td>
    </c:if>
    <c:if test="${not empty rowVo.operation.package}">
        <td>${rowVo.operation.package}</td>
    </c:if>
</c:forEach>

让我感到困惑的是,当第二个EL表达式几乎相同时,从第三个EL表达式抛出异常.

操作是生成的类：

public class Operation {

    //Other properties omitted

    @XmlElement(name = "package")
    protected List<Package> _package;
    protected List<String> jobscopeDescription;
    public List<Package> getPackage() {
        if (_package == null) {
            _package = new ArrayList<Package>();
        }
        return this._package;
    }    
    public List<String> getJobscopeDescription() {
        if (jobscopeDescription == null) {
            jobscopeDescription = new ArrayList<String>();
        }
        return this.jobscopeDescription;
    }
}

这些文件在迁移期间没有更改,并且在WAS 6.1上运行良好.有没有人知道这里有什么问题？

解决方法:

在WebSphere Application Server v8.0及更高版本中,负责检查保留关键字作为EL变量标识符的使用的代码得到了增强,从而使检查更加严格.变量检查代码不仅检查保留的EL关键字,还检查Java保留关键字.
