You need to convert all quote characters in the value to the corresponding
HTML character entities: single quotes to "'" and double quotes to """.
If you download my JSP book examples, you can use the included StringFormat
utility class to convert the string, like this:
<%@ page import="com.ora.jsp.util.StringFormat" %>
...
<input type=text name="txttest1"
value="<%= StringFormat.toHTMLString(test) %>">
All book examples are available here:
