In Tomcat5, the method of previous processing Tomcat4 cannot be applied to handle the request to be submitted directly through the URL. The Internet is found to find the most perfect solution. Don't be converted every place, and regardless of GET, and POST normal. Write a document, posted it, I hope that people who have the same problem are no longer like me :-)
Problem Description:
1 Form submitted data, using the string returned by Request.GetParameter ("xxx") is garbled or? ?
= = 10, if the GET request is garbled when the server is REQUEST. GetParameter ("name"); Press Tomcat4 to set Filter No use or use Request.SetCharacterencoding ("GBK");
Reason:
1 Tomcat's J2EE implementation processes the form of POST mode to process parameters to process the default ISO-8859-1.
2 Tomcat uses the request for Query-String in the Query-String process to process the POST method. (Different from Tomcat4, set the setcharacterenceeEncoding ("GBK").
Solution:
First all JSP files are plus:
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.)
1) Just copy the% Tomcat installation directory% / WebApps / servlets-example / web -incodingfilter.class file to copy 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) complete.
2 Get method solution
1) Open Tomcat's server.xml file, find blocks, join the following line: uriencoding = "GBK"
The complete should be as follows:
Enablelookups = "false" redirectport = "8443" acceptcount = "100" debug = "0" connectionTIMEOUT = "20000"
DisableUploadTimeout = "True"
Uriencoding = "gbk" />
2) Restart Tomcat, everything OK.
