Error when I try deploy application to tomcat7 server

Question

I am trying deploy a web application to tomcat7 via eclipse luna, but I am getting this error:

Uploading: http://localhost:8080/manager/text/deploy?path=%2Floja  [INFO] I/O exception (java.net.SocketException) caught when processing request: Connection reset [INFO] Retrying request Uploading: http://localhost:8080/manager/text/deploy?path=%2Floja  [INFO] I/O exception (java.net.SocketException) caught when processing request: Connection reset [INFO] Retrying request Uploading: http://localhost:8080/manager/text/deploy?path=%2Floja  [INFO] I/O exception (java.net.SocketException) caught when processing request: Connection reset [INFO] Retrying request Uploading: http://localhost:8080/manager/text/deploy?path=%2Floja  [INFO] ------------------------------------------------------------------------ [INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [INFO] Total time: 4.936 s [INFO] Finished at: 2014-08-15T22:10:04-03:00 [INFO] Final Memory: 13M/112M [INFO] ------------------------------------------------------------------------ [ERROR] Failed to execute goal org.apache.tomcat.maven:tomcat7-maven-plugin:2.2:deploy (default-cli) on project loja: Cannot invoke Tomcat manager: Connection reset -> [Help 1] [ERROR]  [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

[ERROR]  [ERROR] For more information about the errors and possible solutions, please read the following articles: [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException 

I also try deploy to tomcat8, but I get this same error.

In my pom.xml, I have this configuration related to this operation:

  <build>     <finalName>loja</finalName>     <plugins>         <plugin>            <groupId>org.apache.tomcat.maven</groupId>            <artifactId>tomcat7-maven-plugin</artifactId>            <version>2.2</version>            <configuration>                 <url>http://localhost:8080/manager/text</url>                 <server>TomcatServer</server>                 <path>/loja</path>                 <username>user001</username>                 <password>123</password>            </configuration>         </plugin>         <plugin>             <groupId>org.apache.maven.plugins</groupId>             <artifactId>maven-war-plugin</artifactId>             <configuration>                 <failOnMissingWebXml>false</failOnMissingWebXml>             </configuration>         </plugin>     </plugins> </build> 

Anyone knows what's happening here?

UPDATE

I try deploy the application with the command mvn:tomcat7 deploy -X and the output was that:

Answer 1

By default Tomcat has a max upload size of 50MB. (I.e max size of WAR file)

If you require larger file, try increasing max-file-size and max-request-size within the tomcat web.xml. Note: those values are both stored in bytes.

Edit .../webapps/manager/WEB-INF/web.xml. (Ensure the file sizes are larger than the war file your trying to upload). I.e if you require 80MB WAR,

  <max-file-size>82914560</max-file-size>   <max-request-size>82914560</max-request-size> 

Then restart apache tomcat.

Ok, I had the same issue with tomcat7.

[INFO] I/O exception (java.net.SocketException) caught when processing request: Connection reset [INFO] Retrying request Uploading: http://localhost:8080/manager/text/deploy?path=%2iplover  [INFO] I/O exception (java.net.SocketException) caught when processing request: Connection reset [INFO] Retrying request Uploading: http://localhost:8080/manager/text/deploy?path=%2iplover  [INFO] I/O exception (java.net.SocketException) caught when processing request:         Connection reset [INFO] Retrying request Uploading: http://localhost:8080/manager/text/deploy?path=%2iplover 

I could not get it to work with

mvn tomcat7:redeploy  

as mentioned here.

My WAR wasn't very large, just 4MB.

Here was the root problem and solution

It is important that your tomcat-users.xml has the correct roles setup. I ONLY had the role manager setup. Adding manager-script seems important and completely solved my problem.

<role rolename="manager"/> <role rolename="manager-script"/> <role rolename="manager-gui"/> <user username="admin" password="admin" roles="manager,manager-gui,manager-script"/>
