问题
When I am trying to display Chinese characters in my JSP page, then it will display junk characters.
What did I do wrong?
I have included the below line to my JSP on the top, and even now, the issue is not getting fixed:
<%@page contentType="text/html;charset=UTF-8" pageEncoding="UTF-8"%>
<%@ page import="java.util.*"%>

Here's my web.xml file:
<?xml version = '1.0' encoding = 'GBK'?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns /javaee/web-app_2_5.xsd"
version="2.5" xmlns="http://java.sun.com/xml/ns/javaee">
</web-app>
Servlet:
public class OrganizationLoadServlet extends HttpServlet {
private static Logger log = Logger.getLogger(OrganizationLoadServlet.class);
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
HttpSession session = request.getSession();
Organization[] orgs = (Organization[])session.getAttribute(WorklistappConstants.SESS_ATTR_PREFS_ORGANIZATIONS);
if (orgs == null) {
orgs = getFilteredOrgs(request);
session.setAttribute(WorklistappConstants.SESS_ATTR_PREFS_ORGANIZATIONS, orgs);
}
log.info("Before: " + response.getCharacterEncoding());//Here I am getting "iso-8859-1"
StringBuffer sb = new StringBuffer();
String dislayName = null;
for (int i = 0; i < orgs.length; i++) {
Organization org = orgs[i];
dislayName = org.getOrgDisplayName();
sb.append("<ITEMS>");
sb.append("<LABEL><![CDATA[" + dislayName + "]]></LABEL>");
sb.append("<VALUE><![CDATA[" + org.getOrgId() + "]]></VALUE>");
sb.append("</ITEMS>");
}
response.setContentType("text/xml");
response.setHeader("Cache-Control", "no-cache");
response.getWriter().write("<?xml version=\"1.0\" encoding=\"iso-8859-1\"?><ITEM>" + sb.toString() + "</ITEM>");
log.info("After: " + response.getCharacterEncoding());//Here I am getting "iso-8859-1"
}
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
this.doGet(request, response);
}
private Organization[] getFilteredOrgs(HttpServletRequest request) {
//code
return orgs;
}
private Organization[] filterOrganizationsByUserOrgs(Organization[] orgs, List<Long> userOrgIdList) {
//code
return filteredOrgs;
}
private List<Long> getUserOrgIdList(String userId) throws Exception {
//code
return userOrgIdList;
}
private String getUserID(HttpServletRequest request) throws IOException {
//code
return wfCtx.getUser();
}
}
Please see the comments in the Servlet class. If I change iso-8859-1 to utf-8, then I am not able to access the application.
Why is this issue occurring?
回答1:
Try this
- After adding your Chinese Character Save your JSP under UTF-8 encoding rather saving it in ISO-8859-1
- Try adding this line
<%@ page contentType="text/html; charset=UTF-8" %>at your JSP Header
Hope it helps.
回答2:
Have you ever tried to use lang attribute for your page?
Something like this:
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xml:lang="zh">
回答3:
The JSP Header that you are using is correct.
But, I think problem might be in the project's encoding setting.
UTF-8 is not default content type in jsp. So you have to change
project's text file encoding to utf-8.
I have no Idea in JDeveloper.... But In Eclipse You can change this way.
Right Click In Project --> Properties --> Under Resource(Text File Encoding should be selected in "Inherited from Container(UTF-8)"
回答4:
Here, the problem is with CDATA. In Servlet, we used iso-8859-1 for sending xml response in xml format. When we tried with UTF-8, the response in xml format not being generated. So instead of sending xml response from servlet to jsp, we used to send that response as html format and displayed as html response on jsp page. This helps in fixed my issue.
In Servlet we modified
sb.append("<option value="+org.getOrgId()+">"+dislayName+"</option>");
response.setContentType("text/html;charset=UTF-8");
response.setHeader("Cache-Control", "no-cache");
response.getWriter().write(sb.toString());
JSP
$('#orgId').html("<option value=\'-1\'>------------ Select Organization ------------</option>"+xmlResponse);
