[SOLVED] Unable to read and write Japanese folder structure in Tomcat 7, but it works for a Docker container

Unable to read and write Japanese folder structure in Tomcat 7, but it works for a Docker container

I get a FileNotFoundException while reading a Japanese folder structure from a Tomcat 7 web application in CentOS 7. However, it's working in a Docker container and direct Java console execution.

Both Docker and normal tomcat7 setups and configurations are the same.

We have done the following configurations:

Tomcat Server server.xml - In the Connector tag add URIEncoding attribute as:

<Connector port="8080"
           protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443"
           URIEncoding="UTF-8"/>

catalina.sh - added following:

export JAVA_OPTS="$JAVA_OPTS -server \
   -XX:-UseGCOverheadLimit \
   -Djava.awt.headless=true \
   -Djavax.servlet.request.encoding=UTF-8 \
   -Dfile.encoding=UTF-8"

export CATALINA_OPTS="$CATALINA_OPTS \
   -Dfile.encoding='UTF-8'"`

Executed the following command to change the server language:
```
export LC_ALL=en_US.UTF-8
```

Solution

Upgrade Tomcat7 to tomcat9 or Tomcat7.0.109. The support is not available in Tomcat7 Early versions
