Problem Description: 1 The data submitted by the form is garbled with the string returned by Request.GetParameter ("XXX") or? ? 2 Directly via URL such as http: ///localhost/a.jsp? Name = China, such GET requests are garbled when using Request. GetParameter ("name"); Press Tomcat4 to set Filter Or use Request.setCharacterencoding ("GBK"); no matter how this: 1 Tomcat's J2EE implementation, the process parameters submitted to the form of the POST mode prompt to process the request for the 2 Tomcat to the GET method. When the Query-String is handled, the POST method is different. (Different from Tomcat4, set the setcharacterenceeEncoding ("GBK"). Workaround: 1 Implement a filter. Set the processing character set to GBK. (There is a complete example in Tomcat's WebApps / Servlet-Examples directory. Please refer to Web.xml and setcharacterencodingfilter configuration.) 1) Just install the% Tomcat installation directory% / WebApps / servlets-example / web-inf / class / filters The /SetCharacterencodingFilter.class file is copied to your webapp directory / filters, if there is no Filters directory, create one.
2) Join the following lines in your web.xml: set character encoding filters.setcharacterencodingfilter Encoding gbk set character encoding / * 3) Finish .2 GET method solution 1) Open Tomcat's server.xml file, find the following block, join the following line : URIEncoding = "GBK" complete shall be as follows: 2) Restart Tomcat, everything OK.
Perform the following JSP page page test is successful
<% @ Page ContentType = "text / html; charset = GB2312"%>
<% @ Page Import = "java.util. *"%>
<%
String Q = Request.getParameter ("Q");
Q = Q == NULL? "No value": q;
%>

<p><body></p>
<p>You are submitted:</p>
<p><% = q%></p>

<p><form action = "tcnchar.jsp" Method = "post"></p>
<p>Enter Chinese: <input type = "text" Name = "q"> <input type = "submit" value = "OK"> <br></p>
<p><a href="tcnchar.jsp?q= 中国"> By GET method submit </A></p>

<p>Test Results If you enter a text box or a hyperlink will display: You submit "China", explain success !!!!!</p>
