chinese characters and bean tags
I have problem to show chinese characters stored in MySQL database with
use of struts bean tag. Data is read out using Hibernate. When I call
myHibernateObject.getMyProperty() method - everything works fine. But
using <bean:write name="myHibernateObject" property="myProperty"/> does
show text in this notation: &#xxxx &#xxxx. Same problem occurres when I
use this bean in struts form with <html:text name="myHibernateObject"
property="myProperty"/>
Encoding of database is set up properly to gb2312. JSP page uses UTF-8
encoding. How can I set character encoding for struts bean tag ? Or where
is the problem ?
Thanks a lot for your help.

Hi Frank,
I did look at JWP but got intimidated by the Javadocs. I thought I would get documentation about
the Tags I can use, but instead I found Java classes, and with no signpost for where to begin.
You have suggested to look at the sample application, which I'll do.
Thanks,
Anupam.

I suggest AjaxTags from Java Web Parts:
http://javawebparts.sourceforge.net
Hit the javadocs link, then jump to the taglib package, the documentation
for the package should give you a good idea what its all about, then you
can grab the JWP distro and try out the sample app for some working
examples of what is possible. This is, I believe, the easiest way to add
AJAX to any Java-based webapp app, be it Struts or otherswise, especially
for those that don't want to touch Javascript at all. Yes, I wrote it :)
If you want to get a feel for doing naked AJAX (i.e., just plain
Javascript) within a Struts app specifically, I suggest:
http://struts.sourceforge.net
Check out the AjaxChat application (yes I wrote that too!). You already
said you don't want to write all the Javascript though, so that migth be
of less interest than AjaxTags may be.
I also wrote an introductory article to AJAX:
http://www.omnytex.com/articles
It deals with Struts as well, but to a lesser extent. Again though, you
would do the coding yourself, so might not be what you want anyway.
Feel free to fire any questions at me if you decided to use AJAX, in
whatever way.

Hi,
I did spend much time on OpenLazlo but gave it up because of lack of appropriate constructs for
dynamic GUI design and lack of proper support.
I would love to use Ajax since it is a light-weight solution. But don't want to deal with all
the Javascript coding. I wonder what people are using these days to do Ajax development in a
struts environment?
I'm trying to find an integrated environment that works within Struts. Although using Struts is
also not a requirement.
I will look at SiteMesh.
Thanks,
Anupam.

Struts Menu Vs Struts Layout
Posted by Agnisys <ag...@yahoo.com>.
Hi,
I need to create an application with lots of Dynamic GUI features (like dynamic number of
Panes). Which one is more suitable for the job: Struts Menu or Struts Layout?
Or is there a more appropriate 3rd option?
Thanks for any pointers.
Anupam.

Hello Jose,
exactly! This solves my problem. Fortunately I do not have so many chinese
fields in my allplication. So it should not be complicated to close all
possible security holes.
Thanks a lot,

Have you tried using <bean:write name="chinatext" property="text"
filter="false"/>?
filter="false" means the tag will not "escape" HTML characteres... the
default value is true IIRC. Maybe during that filtering it is also escaping
non-ASCII characters? (wild guess here, since the last Struts version I used
was 1.1)
The problem with filter="false" is that is opens your app to all sorts of
cross-site scripting security holes... so you would have to guarantee the
user cannot enter some javascript code that will end up being printed by
this tag later on... =(

Do you have the JSP page directive set as suggested above? The HTML
<META> tags are best considered to be "hints".

So, here the most important part of my JSP code:
<head>
<html:base/>
<title>test</title>
<META http-equiv="Content-Type" content="text/html;charset=UTF-8">
</head>
<%
/*
* +++ TEST CASE 1 +++
*/
// business logic for obtaining all hibernated objects
BOGeneric bo = new BOGeneric();
List l = bo.find("ChinaText", new Criterion[] {}, new Order[] {});
pageContext.setAttribute("names", l);
// runs it throung and prints out all the texts
for (Iterator i=l.iterator(); i.hasNext();) {
out.println(((ChinaText)i.next()).getText() + " : ");
}
%>
<!--
+++ TEST CASE 2 +++
now the same using struts
-->
<logic:iterate id="chinatext" collection="<%=l%>">
<bean:write name="chinatext" property="text"/> -
</logic:iterate>
In the first test case I get correct encoded chinese texts. In the second
one I get only &#xxxx strings.

In that case I'm not sure what's going on... Can you post a short JSP

I have verified it with <%=myObject.getProperty()%> in the JSP. In this
case I got chinese string with right encoding. But using <bean:write
name="myObject" property="property"/> produces string in this wrong
encoding format: &#xxxx. Charset of the JSP page is set to UTF-8.

How are you verifying that what you get back from the database is
correct? If anywhere in the data retrieval pipeline is using the wrong
encoding, you'll get corrupted data. Try hard-coding an output value to
see if you are able to display that correctly.
If that fails, it must be something in the way you've written your JSP;
make sure that you have the UFT-8 charsett declared in the content type
of the response -- e.g. with <%@ page contentType="text/html;
charset=UTF-8"%> and/or HTML META-tags.
