Change Tomcat's Charset.defaultCharset in windows

Question

I'm using tomcat 6.0.32 in windows 7. Inside a very simple servlet, inside the init method, I'm printing:

System.out.println(Charset.defaultCharset());

The output is:

windows-1253

As far as I understand this is how tomcat start's in the JVM since I'm printing the same in standalone java class and I get "UTF8" as a response.

So, how can I change this to UTF-8?

thanks

did you try `request.getCharacterEncoding();` ? See what it prints, Anyway you can change the character encoding.. but it varies depends on the requirement. Have look at this wiki page http://wiki.apache.org/tomcat/FAQ/CharacterEncoding#Q1 — RP-, Jul 05 '12 at 11:21
I cant access request since I'm working inside the init method. In any case this is not a request-repsonse issue since I need to have UTF8 encoding in order to read files and not to send response in UTF8 encoding. — nonouco, Jul 05 '12 at 11:31

Just create a setenv.bat file inside the TOMCAT/bin directory with the following contents:

set "JAVA_OPTS=%JAVA_OPTS% -Dfile.encoding=UTF8"

Is the correct configuration -Dfile.encoding=UTF-8 or -Dfile.encoding=UTF8? I think that it should be UTF-8 – Marco Altieri Sep 24 '15 at 15:42
The correct is as described in the answer, i.e. UTF8 - check these two: 1) http://stackoverflow.com/questions/6031877/jvm-property-dfile-encoding-utf8-or-utf-8 2)http://docs.oracle.com/javase/6/docs/technotes/guides/intl/encoding.doc.html – nonouco Sep 25 '15 at 15:18

You may also add this setting in the Tomcat 7.0 windows service manager.

This setting works for me.I have one more question is this setting requires only in windows os or we need to define this in linux also? – Yogesh Bombe Feb 26 '19 at 11:55

For Tomcat running as a Windows service neither %JAVA_OPTS% and neither setenv.bat answers works in my case.

I set the option "-Dfile.encoding=UTF8" in registry:

"HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software Foundation\Procrun 2.0\tomcatstackTomcat\Parameters\Java --> Options*

Then it works.

Try setting the (Windows) environment variable JAVA_TOOL_OPTIONS to -Dfile.encoding=UTF-8 and start the Tomcat Server.

Unfortunately this is not working. Setting -Dfile.encoding=UTF-8 is the correct approach but I don't thin that tomcat is appending JAVA_TOOL_OPTIONS to JAVA_OPTS. In any case I found the solution. Check below. – nonouco Jul 05 '12 at 11:38
