Eclipse 没有为我的 jsp 显示任何错误。然而，当我尝试在 Tomcat 中访问它时，我得到了这个错误：

谁能推荐其他用于查找 JSP 编译错误的工具？

【问题讨论】：

  • 这是完整的堆栈跟踪吗？您正在部署什么版本？
  • Tomcat 6、Struts 1.2.7、Java 1.6、Eclipse Kepler
  • 你说得对，我还有更多要补充的。

标签： jsp struts-1 taglib


【解决方案1】：

在 Eclipse 中创建一个新的临时 Java 项目。在 Tomcat 的工作目录中查找存在编译问题的文件（看起来是 jvnFindingsContent_jsp.java）并将其添加到您的项目中。您还需要添加一些 Tomcat 库来解决一些未知的导入问题。我只想添加所有这些 - 它会更快。然后，您需要让 Eclipse 将该文件移动到正确的包中，此时您应该有一个 Eclipse 可以尝试编译的 java 文件。然后，您应该能够看到 Eclipse 在编译时遇到了什么问题，并希望这将映射回 JSP 中现在明显的错误。

根据 JSP 的结构，您可能需要将一些其他 java 文件添加到项目中，例如为标记文件生成的文件。

【讨论】：

  • 我怎么知道什么 eclipse 编译有问题？
  • Eclipse 会像任何其他 Java 文件一样用编译错误标记 Java 文件。
  • 显然，这是 JSP Eclipse 中的一个错误，没有拾取：T_ID%>');"id= vs T_ID%>');" id= 标签之间的空格是错误的。
  • 一位同事在使用 Tomcat 7 时收到此错误：“JSP 规范要求属性名称前有空格。”
【解决方案2】：

也许在 Eclipse 中启用 JSP 语法和内容验证器？

Eclipse->窗口->首选项->验证；验证是否检查了构建或可选手册。
