If you have a problem with GET parameters in URL. Edit Tomcat's conf/server.xml file and add the following attribute to the correct Connector element: URIEncoding="UTF-8".


   8080" maxHttpHeaderSize="8192"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" redirectPort="8443" acceptCount="100"
               connectionTimeout="20000" disableUploadTimeout="true"
               URIEncoding="UTF-8"
   />
