使用Maven，Tomcat 7和Websocket构建可执行的War / Jar

Question

I'm trying to build an executable WAR/JAR using Maven and Tomcat 7. The Project contains Websocket and REST API.

In order to do that, I added the following plugin to the pom.xml file:

    <groupId>org.apache.tomcat.maven</groupId>
            <artifactId>tomcat7-maven-plugin</artifactId>
            <version>2.1</version>
            <executions>
                <execution>
                    <id>tomcat-run</id>
                    <goals>
                        <goal>exec-war-only</goal>
                    </goals>
                    <phase>package</phase>
                    <configuration>
                        <path>/TransSafeGWService</path>
                        <enableNaming>false</enableNaming>
                        <finalName>standalone.jar</finalName>
                        <charset>utf-8</charset>
                    </configuration>
                </execution>
            </executions>

After that, since REST Service was working but Websocket Service was not, I added other dependencies to the plugin:

        <plugin>
            <groupId>org.apache.tomcat.maven</groupId>
            <artifactId>tomcat7-maven-plugin</artifactId>
            <version>2.1</version>
            <executions>
                <execution>
                    <id>tomcat-run</id>
                    <goals>
                        <goal>exec-war-only</goal>
                    </goals>
                    <phase>package</phase>
                    <configuration>
                        <path>/TransSafeGWService</path>
                        <enableNaming>false</enableNaming>
                        <finalName>standalone.jar</finalName>
                        <charset>utf-8</charset>
                    </configuration>
                </execution>
            </executions>
            <dependencies>

                <dependency>
                    <groupId>org.apache.tomcat</groupId>
                    <artifactId>tomcat7-websocket</artifactId>
                    <version>7.0.67</version>
                </dependency>

                <dependency>
                    <groupId>org.apache.tomcat</groupId>
                    <artifactId>tomcat-util</artifactId>
                    <version>7.0.67</version>
                </dependency>

                <dependency>
                    <groupId>org.apache.tomcat</groupId>
                    <artifactId>tomcat-coyote</artifactId>
                    <version>7.0.67</version>
                </dependency>

            </dependencies>
        </plugin>

Using that dependencies, I get this kind of error:

java.lang.NoSuchMethodError: org.apache.catalina.connector.RequestFacade.upgrade(Ljava/lang/Class;)Lorg/apache/coyote/http11/upgrade/servlet31/HttpUpgradeHandler;

In this case what could be the problem?

Answer 1

I think your issue is probably with the wrong version of servlet api. Tomcat 7 supports 3.0 and below but it seems that you are using servlet version 3.1.

Your exception shows this method not found and this is only part of servlet 3.1 or above.

Since: 
 Servlet 3.1

Even though you have not included the web.xml in the question, the stacktrace leads to this resolution

Please see your web.xml has this declaration.

  <web-app version="3.0"
  xmlns="http://java.sun.com/xml/ns/javaee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="
    http://java.sun.com/xml/ns/javaee
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

Update:

You are using version 2.1 for tomcat7-maven-plugin which uses tomcat version 7.0.37. And then in the dependencies you are trying to use tomcat jars with a different version 7.0.67. You must use the same version for both.

You have two possibilities:

1. Either set the version of all jars to 7.0.37

2. You can use the latest version 2.2 of tomcat7-maven-plugin and use the property for setting the tomcat version . I would prefer this one. May be you can set this property with 2.1 also. You can try it.
