I think you summed it up quite well in your own answer.

In the process of UTF-8-ing(?) from end to end you might also want to make sure java itself is using UTF-8. Use -Dfile.encoding=utf-8 as parameter to the JVM (can be configured in catalina.bat).

To add to kosoant's answer, if you are using Spring, rather than writing your own Servlet filter, you can use the class org.springframework.web.filter.CharacterEncodingFilter they provide, configuring it like the following in your web.xml:

 <filter>
    <filter-name>encoding-filter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
       <param-name>encoding</param-name>
       <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
       <param-name>forceEncoding</param-name>
       <param-value>FALSE</param-value>
    </init-param>
 </filter>

    <filter-name>encoding-filter</filter-name>
    <url-pattern>/*</url-pattern>

Character Encoding - Apache Tomcat, In a Grails project we had the case that html links didn't work. The url wasn't encoded as UTF-8, so the browser (Mozilla Firefox 3.5) couldn't handle the url correctly. To fix the problem in Tomcat 6, you have to edit the file server.xml. Change HTTP/2 - concepts and status quo for Java EE developers23. utf 8 filter spring (9) .

This is for Greek Encoding in MySql tables when we want to access them using Java:

Use the following connection setup in your JBoss connection pool (mysql-ds.xml)

<connection-url>jdbc:mysql://192.168.10.123:3308/mydatabase</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<user-name>nts</user-name>
<password>xaxaxa!</password>
<connection-property name="useUnicode">true</connection-property>
<connection-property name="characterEncoding">greek</connection-property>

If you don't want to put this in a JNDI connection pool, you can configure it as a JDBC-url like the next line illustrates:

jdbc:mysql://192.168.10.123:3308/mydatabase?characterEncoding=greek

For me and Nick, so we never forget it and waste time anymore.....

Choosing & applying a character encoding, varies with the technical specification employed, specifying no encoding at all will In other words, Java is said to have the possibility to absorb all the differences of Conforming to RFC3280, WebLogic Server supports UTF-8 encoding with Therefore when webapp.encoding.default is changed, the JSP files of the� The result of this is that it's quite impossible for the webapp to correly handle the request parameters from GET requests as some characters are encoded in latin1 and others in UTF-8. Notice: POST requests do work as browsers encode all request parameters from forms completely in UTF-8 if the page is defined as being UTF-8. Stuff to read

Solving Tomcat Encoding Problems in UTF-8 Webapps, Solucionando problema Encoding UTF-8 en Java Webapp sobre Tomcat .com/ questions/138948/how-to-get-utf-8-working-in-java-webapps Remove characters not-suitable for UTF-8 encoding from String. UTF-8 is not a character set, it's a character encoding, just like UTF-16.. UTF-8 is capable to encode any unicode character and any unicode text to a sequence of bytes, so there is no such thing as characters not suitable for UTF-8.

Internationalization in WebLogic Server, GitHub is home to over 50 million developers working together to host and . com/questions/138948/how-to-get-utf-8-working-in-java-webapps� Java successfully handles it, as it support UTF-16 but my mySql table support UTF-8 and thus insertion fails. I was trying to implement some way in business logic itself, to remove any characters which is not suitable for UTF-8 encoding. Currently I am using this code: new String(java.nio.charset.Charset.forName("UTF-8").encode(myString).array());

  • See also stackoverflow.com/questions/153527/…
  • These steps also work with Struts/tiles and a postgres database.
  • Two comments: 1) in HMTL-meta tags you included a xml declaration. Remove it, it would only trigger browsers in quirks mode, you don't want to have that. Also, the HTML meta tags are in fact already implicitly done by JSP pageEncoding, so you could even leave it away. 2) in MySQL database and tables you used utf8_swedish_si, this should have been utf8_unicode_ci. You could even leave the collation away, just CHARACTER SET utf8 is enough.
  • Neither of the documents I consulted regarding HTML meta tags and quirks mode (e.g. ericmeyeroncss.com/bonus/render-mode.html, en.wikipedia.org/wiki/Quirks_mode) indicate that the presence of <meta http-equiv='Content-Type' has any impact on the rendering mode.
  • As an interesting side note you may also want to be aware that if you have a listener that accesses a request parameter, you will need to add a listener that sets the charset instead of a filter because the listeners are executed before the filters. I followed all the steps and it still didn't work because of this. Just thought I would pass along this info, in case anyone else has a similar problem.
  • ## Tomcat with Apache ## One more thing If you are using Apache + Tomcat + mod_JK connector then you also need to do following changes: 1. Add URIEncoding="UTF-8" into tomcat server.xml file for 8009 connector, it is used by mod_JK connector. <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" URIEncoding="UTF-8"/> 2. Goto your apache folder i.e. /etc/httpd/conf and add AddDefaultCharset utf-8 in 'httpd.conf' file. Note: first check that it is exist or not. If exist you may update it with this line. You can add this line at bottom also.
  • This helped me, I did everything mentioned but JVM encoding was windows-1250 as soon as I changed to UTF-8 it worked flawlessly.
  • Where do you add that in the Catalina.bat file, please?
  • This filter must be the first filter in web.xml
  • I would still prefer UTF-8 above Greek (and convert your current Greek data to UTF-8) so that your application is ready for world domination.
