Reading Non Plain Ascii From Html Forms Into Java Servlet Applications

Java Programming Tricks

Reading non plain ASCII from HTML forms into Java Servlet Applications:

When you want to read extended values (e.g. ISO-8859-1) from a HTML Form into a Java Servlet, make sure you set the correct Characterset, before reading the values, or you will get only 7-Bit characters.

 // Get HTML-Form Parameters
 
 import java.util.*;
 import oracle.html.*;
 import oracle.owas.wrb.services.http.HTTP;
 
 public class GetFormParm {
 
   protected HTTP http = null;
 
   // Constructor
   public GetFormParm() {
     this.http = HTTP.getRequest();
   }
 
   // Get URL Parameter for strKey
   public static String getURLParm(HTTP http, String strKey) {
     String strValue;
 
     // Set URL character set (default ISO-8859-1)
     http.setURLCharacterSet("ISO-8859-1");
     strValue = http.getURLParameter(strKey);
     if (strValue == null) { strValue = ""; }
     if (strValue.compareTo("") == 0) { strValue = ""; }
 
     return strValue;
   }
 }
