UTF-8 Configuration in WebSphere, WebLogic, Tomcat, TC Server, JBoss

Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

UTF-8 has become dominant character encoding for the web applications.

In this article, I will talk about how to configure UTF-8 in IBM WAS, Oracle Weblogic, Tomcat, TC Server & JBoss.

WebSphere Application Server

Login into WebSphere Administrative Console
Expand Servers >> Application Servers
Click on Application Server (JVM) you want to enable UTF-8
Expand Java and Process Management under Server Infrastructure
Click on Process Definition
Click on Java Virtual Machine
Add the following parameter in Generic Java Arguments

-Dclient.encoding.override=UTF-8

Click Ok, Sync the node if applicable
Restart Application Server (JVM) for changes to take effect.

Oracle WebLogic Server

Go to Weblogic Domain path
Go to bin folder
Add following parameter in setDomainEnv.sh under JAVA_OPTS variable.

-Dfile.encoding=utf8

Restart Weblogic server for changes to take effect.

Tomcat

Go to tomcat home (installation) folder
Go to conf folder
Add the following parameter in server.xml under Connector port.

URIEncoding="UTF-8"

Note: if you have multiple Connector ports, you must add them under all.

Go to tomcat home (installation folder)
Go to bin folder
Add the following parameter in catalina.sh under JAVA_OPTS variable.

-Djavax.servlet.request.encoding=UTF-8 -Dfile.encoding=UTF-8

Ex:

JAVA_OPTS=”-Djavax.servlet.request.encoding=UTF-8 -Dfile.encoding=UTF-8”

Restart Tomcat Server for changes to take effect.

TC Server

Go to TC Server instance folder
Go to conf folder
Add the following parameter in server.xml under Connector port.

URIEncoding="UTF-8"

Go to TC Server instance folder
Go to bin folder
Add following in setenv.sh under CATALINA_OPTS variable

-Djavax.servlet.request.encoding=UTF-8 -Dfile.encoding=UTF-8

Ex:

CATALINA_OPTS="-Djavax.servlet.request.encoding=UTF-8 -Dfile.encoding=UTF-8"

Restart TC Server for changes to take effect.

JBoss Application Server

Go to JBoss installation path
Go to bin folder
Add the following parameter in standalone.conf under JAVA_OPTS

-Dfile.encoding=UTF-8

Restart JBoss Server for changes to take effect.

UTF-8 Validation Tools

You can use following online tool to validate if your web application is UTF-8 supported

I hope above instructions help you in configuring UTF-8 in multiple application servers.
