(java.net.SocketException) caught when processing request: Connection reset by peer: socket write error

Question

I had a I/O exception (java.net.SocketException) caught when processing request: Connection reset by peer: socket write error problem When using maven plugin to deploy tomcat This problem has haunted me for days. I couldn't use tomcat7:deploy to upload my war file via maven plugin, due to connection reset by peers error. Here's part of my pom.xml

<build>
        <finalName>Project</finalName>
    <pluginManagement>
        <plugins>
            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>2.3.2</version>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                </configuration>
            </plugin>
             <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                 <version>2.2</version>
                <configuration>
                    <server>tomcat</server>
                    <url>http://myserver/manager/text</url>
                    <username>admin</username>
                    <password>admin</password>
                    <path>/plainart</path>
                </configuration>
            </plugin>
        </plugins>

    </pluginManagement>

and here's the console log

and the remote tomcat-user.xml is configured.

I don't know how to fix this problem. If there's any infomation useful to troubleshooting that I could offer, please let me know.

Thanks in advance

Answer 1

Try these ,

1. use redeploy instead of deploy

2. Default war size in tomcat is 50 MB, try to increase that if your war is bigger than 50 MB

3. Lots of users listed cause to me missing roles in tomcat-users.xml. Try adding manager-script role if missing , Question Link

4. Tomcat7 plugin might be picking server details from the maven conf settings.xml instead of .m2\\settings.xml .Adding server information in that file might resolve issue.

Answer 2

In addition to @Sabir Khan's answer. You need to check if the value of server in the plugin configuration is the same as the server id in the settings.xml

So in the pom.xml you are having :

<plugin>
     ...
     <configuration>
          ...
           <server>MyTomcatServer</server>
          ...
     </configuration>
     ...
</plugin>

be sure in the settings.xml of maven you have :

<servers>
    ...
    <server>
        <id>MyTomcatServer</id>
        <username>username_here</username>
        <password>password_here</password>
    </server>
    ...
</servers>

Otherwise, tomcat will try to use admin account (if it is not configured, the server will refuse the auth)
