小编Anu*_*nup的帖子

我正在使用maven来构建在tomcat服务器上部署的项目.构建过程成功完成但是当我尝试在tomcat 7上部署项目时抛出错误.我可以看到twelemonkey-servlet.jar存在于WEB-INF的lib文件夹中.

的pom.xml

      <repository>
        <id>project.local</id>
        <name>project</name>
        <url>file://${project.basedir}/repo</url>
    </repository>




 <dependency>
        <groupId>com.twelvemonkeys.imageio</groupId>
        <artifactId>imageio-metadata</artifactId>
        <version>3.06</version> 
    </dependency>

  <dependency>
        <groupId>com.twelvemonkeys</groupId>
        <artifactId>twelvemonkeys-servlet</artifactId>
        <version>3.08</version> 
    </dependency> 

构建成功但在部署时我遇到异常
