tuckey-urlrewrite not working with maven

My project was on ant and working fine. Thought of moving it to maven even including tomcat as dependency so that I do not have to install tomcat separately.

When I execute mvn tomcat:run ; it is able to build the application and getting following error when tomcat starts

My pom.xml has following dependencies:

<dependency>
    <groupId>org.apache.tomcat</groupId>
    <artifactId>servlet-api</artifactId>
    <version>6.0.35</version>
</dependency>
<dependency>
    <groupId>org.tuckey</groupId>
    <artifactId>urlrewritefilter</artifactId>
    <version>4.0.4</version>
</dependency>

I even tried changing versions of tuckey.

open you .m2 and locate the urlrewritefilter-3.1.0.pom. just copy the java servlet dependancy and add it to you pom. by example if you are using version 3.0.1, you must add this

<dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>servlet-api</artifactId>
            <version>2.3</version>
            <scope>provided</scope>
        </dependency>

hope this help.

You've definitely got a dependency conflict on your hands. My suggestions would be to:

  1. Depend on the standard servlet-api artifact, and not Tomcat's
  2. Use the provided scope so that the servlet-api jar doesn't get bundled into your webapp. Tomcat doesn't want you to include it and will issue a warning if you do.

Then your POM should have this snippet:

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>org.tuckey</groupId>
    <artifactId>urlrewritefilter</artifactId>
    <version>4.0.4</version>
</dependency>
