我的耳朵应用程序在本地窗口PC上的Tomcat 6上运行良好，但它无法在同一台PC上的Weblogic服务器10.3.6上运行。

Caused By: java.lang.VerifyError: (class: org/springframework/web/servlet/FrameworkServlet, method: processRequest signature: (Ljavax/servlet/http/HttpServletRequest;Ljavax/servlet/http/HttpServletResponse;)V) Incompatible argument to function

以下是我可能与问题相关的pom.xml的一部分。

<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>

<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.1</version>
<scope>compile</scope>
</dependency>

Answer 1

从您的webapp的/WEB-INF/lib文件夹中删除所有特定于Tomcat的库，例如el-ri.jar, el-api.jar。它会使您的webapp与不同品牌/版本的容器不兼容，从而导致此类错误。

可能的原因1：

当您针对不同的库编译时，

java.lang.VerifyError可能是您在运行时使用的结果。

特别阅读本段

You should above all never manually copy/download/move/include the individual servletcontainer-specific libraries like servlet-api.jar, jsp-api.jar, el-api.jar, j2ee.jar, javaee.jar, etc. It would only lead to future portability, compatibility, classpath and maintainability troubles, because your webapp would not work when it's deployed to a servletcontainer of a different make/version than where those libraries are originally obtained from.
