Internationalization/Unicode output from Servlets...

[att1.html]

After some help from others on this board, I was able to accomplish my
          goal of outputting Korean and Japanese characters to an IE5 browser from
          within a WLS v4.5.1-Service-pack-1 servlet.
          I have been able to output and properly display both Korean and
          Japanese characters from within a servlet running on WLS4.5.1 using the
          8-bit Unicode character set (UTF-8).
          Summary: Both straight text output, FreeMarker, and WebMacro were able
          to handle this simple example. I don't know what will happen if you
          try to use WebMacro's more advanced reflection capabilites, but I will
          try to test that also.
          First, you'll have to install the 'Japanese Language Support' and
          'Korean Language Support' for IE5 (obtained from the Windows Update
          site). This should only take a few minutes.
          Now try the following servlet. It should output Japanese characters:
          public void service(HttpServletRequest req, HttpServletResponse res)
          throws ServletException, IOException {
          res.setContentType("text/html; charset=UTF-8");
          PrintWriter out = new PrintWriter(new OutputStreamWriter(res.getOutputStream(), "UTF8"),true );
          String test = new String("<HTML><BODY>\u72ac\u72ac</BODY></HTML>");
          out.println (test);
          out.close();

Robocopy unicode output jibberish log file

When I use the unicode option for a log file or even redirect unicode output from robocopy then try to open the resuting file in notepad.exe or whatever, it just looks like jibberish. How can I make this work or when will Microsoft fix it? Since Microsoft put that option in there, one supposes that it works with something. What is the expected usage for this option?
Yes, I have file names with non-ASCII characters and I want to be able to view them correctly. Without unicode support robocopy just converts such characters into a '?'. It does, however, actually copy the file over correctly, thankfully. I have tried running robocopy from PowerShell and from cmd /u. Neither makes any difference. Also, one odd thing is that if I use the /unicode switch, the output to screen does properly show the non-ASCII characters, except that it doesn't show all of them, such as the oe ligature used in French 'œ'. That was just converted into an 'o' (not even an oe as is usually the case). Again, it does properly make a copy of the file. This just makes it not quite possible to search log results.
Let's see if this post has those non-ASCII characters transmuted when this gets posted even though everything looks fine as I type it. âéèïöùœ☺♥♪

Export unicode data to Excel from Servlet

Hi,
In my application we are export some unicode data to Microsoft Excel 2003 from servlet .
For that i am using the following code.
response.setHeader( "Content-Disposition", "attachment; filename=results.xls" );
response.setContentType( "text/xls" );
theHeader.append("\u30ec\u30dd\u30fc\u30c8 \u30bf\u30a4\u30c8\u30eb");
The above unicode data (japanese character) not displaying properly in Excel (display as "?"). other non unicode things are display properly.
can anyone advise me.

I was having problems writing a unicode (utf-8 or utf-16) csv excel file, found a solution in the end ill post it here in case anyone else is looking.
You need to use the funky encoding x-UTF-16LE-BOM
an example of how to do this is
Writer writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outputFile, true), "x-UTF-16LE-BOM"));
then instead of using commas (,) use tabs (\t)
then in my web.xml i have
<mime-mapping>
<extension>csv</extension>
<mime-type>application/msexcel</mime-type>
</mime-mapping>
this site is a good reference

WML Output From JSP/Servlets

I need some assistance with WML output from someone who knows...
I am writing a small subset of applications for mobile access. When testing them through the OpenWave Emulator (the UP browser) everything works just fine. However..the output varies greatly to where on some machines the login cannot be performed. My only problems tend to occur with forms and the lack of an <input type="submit"/> component.
Here's the WML output of the login screen:
<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.2//EN"
"http://www.wapforum.org/DTD/wml12.dtd">
<wml>
<card id="login" title="Login Form">
<p>Please login.<br/>
<table>
<tr><td>Username:</td></tr>
<tr><td><input name="username" type="text" title="username"/></td></tr>
<tr><td>Password:</td></tr>
<tr><td><input name="password" type="password" title="password"/></td></tr>
</table>
</p>
<do type="accept" label="Login">
<go href="/portal/mobile/vendor/" method="POST">
<postfield name="username" value="$(username)"/>
<postfield name="password" value="$(password)"/>
</go>
</do>
</card>
</wml>Again, in OpenWave's UP browser, I can enter the username and password, then click options --> Login and things work great.
However on the WinWap browser, I only get the labels, no input fields or login option.
Does this WML look properly formed? Any help would be appreciated.

I can't really tell you the fix, as I really can't remember, but I know I had a similar problem once... OpenWave was fine, but the Nokia emulator didn't like it.
I think I ended up having a different DOCTYPE and having the username and password inputs on separate pages.
Does WML support tables?

Multiple Input and Output from a 6534

Hello
I am after some advice regarding my PCI 6543 digital I/O card and the best way to achieve my desired results. I am programming in Visual C++ with Ni-DAQ 7.
I want to generate a pattern output from one of the ports, Port A, following a software command. This pattern consists of a 10uS pulse on DIOA0, that repeats 200 times with a period of 100uS. I want this DIOA0 output line to initiate an input on ports C and D, possibly through the REQ pin. Consequently the input should acquire 200 times for each call to the pattern output.
I want this to repeat, so the pattern output goes again (as in a FOR loop), and the input occurs again for an as yet undetermined number of times.
I have managed to get something worki
ng for 1 iteration, and I can generate multiple pattern outputs, but the inputs only seem to acquire for the 1st iteration. However, if I step through the code in debug mode I can get the input to work correctly.
Any ideas would be gratefully appreciated.
I am still trying to get some earlier problems with this application solved.
Kind Regards
Jamie

Hi Jamie,
There are a couple different ways you can loop from a buffer. You can either use the onboard memory of the 6534 and loop from there or you can specify as a software configuration that the board loop through the PC memory buffer.
For the onboard looping you need to specify the following:
iStatus = Set_DAQ_Device_Info (1, ND_PATTERN_GENERATION_LOOP_ENABLE, ND_ON);
For software, PC memory looping, the following function specifies this:
iStatus = DIG_DB_Config (iDevice, iGroup, 1, 0, 1);
I attached a couple programs that might be of use. Check this post:

Hope that helps. Have a good day.

How to call any .tmpl file from servlet by sending some parameters ?

Hi,
I am new to Java Servlet and HTML template language ( anyfile.tmpl).
I have created simple login authentication with user registration for new user.
If user already exists, after successful login, he should be navigated to INBOX page (that inbox page is some inbox.tmpl file) from SERVLET itself using following BOLD statements given in code below. But its not working.. :-( Please do the needful.
Thank you.
if (session == null) {
     try {
          userName = request.getParameter("login");
          pwd = request.getParameter("password");
          if (!userName.equals("") && !pwd.equals("")) {
          try {
//Database connection, data fetching, query execution etc.
// code will go here
               while (rs.next()) {
               if (userName.equals(rs.getString("username")) & pwd.equals(rs.getString("pwd"))) {
                    String u_name = userName;
                    String ph_no = (new Integer(rs.getInt("ph_no"))).toString();
                    String address = rs.getString("address");
                    session = request.getSession();
                    session.setAttribute("user", userName);
                    String inbox = context.getInitParameter(INBOX);
                    Template inboxTmpl = new Template(inbox);
*                    inboxTmpl.setParam("userName", u_name);*
*                    inboxTmpl.setParam("ph_no", ph_no);*
*                    inboxTmpl.setParam("address", address);*
*                    out.println(inboxTmpl.output());*
                    System.out.println("Login successful..");
                    break;
               rs.close();
     pstmt.close();
con.close();
(P.S - I am forced to use HTML.TEMPLATE(i.e. .tmpl file) instead of JSP)}

Where does Template come from?
But its not working.The other day I called the car repair shop. I told them my car did not work and I wanted them to fix it. They asked what was wrong, whether it did not start, whether suspicious sounds were heard, whether the car did not want to brake any longer, whether it gave a smoke from the exhaustion, whether the wind shield was broken, whether the oil was leaking etc. But I insisted just telling them "it doesn't work".

How to call JSp from Servlet??

Hello,
I want to call JSP page from servlet.I am using Visual Age For java 3.4. What is wrong in my code??
if (userExists) {
f.setErrors("userName","Duplicate User: Try a different username");
getServletConfig().getServletContext().
getRequestDispatcher("/jsp/forms/retry.jsp").
forward(request, response);
I am not able to get the o/p. Pls help.

I can't see anything obvious, but did you take any steps towards doing output before this code (like openning an output stream)?
Not clear what f.setErrors does - presumably stuffs the error message in an attribute of the request.

Applet in jsp from servlet, but error: ClassNotFoundExcep

The problem that I'm having is already mentioned a couple of times in this forum, but unfortunately I haven't found a solution, in thread http://forum.java.sun.com/thread.jspa?forumID=33&threadID=239405 is proposed solution but it's not working for me.
I'm developing a project in IBM's Websphere Developer Studio 5.1.1. and JRE that I'm using for this project is 1.4.2. I have created servlet "CompanyDocument.java" and applet "SimpleApplet.java". Applet was created as single project and then imported into this one, that means that it's contained in current project as "SimpleAppletPackage.jar". I have placed jar in folder "Applets", Websphere automatically creates folder "simpleAppletPackage" and in it's root complied "SimpleApplet.class".
When I put following code in the jsp page applet works correctly when application is runed.
<APPLET code="simpleAppletPackage/SimpleApplet.class" codebase="Applets" archive="SimpleAppletPackage.jar" width="250" height="250"></APPLET>
But I wanted to create jsp from servlet. So I used this code within servlet:
out.print("<APPLET code=\"simpleAppletPackage/SimpleApplet.class\" codebase=\"Applets\"");
out.print("archive=\"SimpleAppletPackage.jar\" width=\"250\" height=\"250\"></APPLET>");
But I get an error (when running, no error when compiling). The error is copied from Java console:
load: class simpleAppletPackage/SimpleApplet.class not found.

In the same time I'm creating some more code from servlet and it works with no errors and is shown in browser properly (it consists of connection to Oracle, formatting table, and presenting data within that table).
Any idea? I'm totally stuck.

In your browser, look at the HTML code that gets sent to the browser and see if there is something wrong with it.
Specifically, I would look at the code near the <APPLET ..></APPLET> tags, both before and after and look for stray quotes, brackets, or what not.
Finally, I would look inside the <APPLET ...> tag. It appears to me that the output will probably be:
<APPLET code="simpleAppletPackage/SimpleApplet.class" codebase="Applets"archive="SimpleAppletPackage.jar" width="250" height="250"></APPLET>See, you may be missing a space between the "Applets" and the archive=. Try making the second out.print look like this:
out.print(" archive=\"SimpleAppletPackage.jar\" width=\"250\" height=\"250\"></APPLET>"); See the extra space at the start of the output?

How to execute package from Servlet

Is the raw output from JSP and XSQLServlet the same?

Hi
Is there is difference between the raw output from XSQLServlet and JSP? For example, assuming the same content is being generated, is there some additional header information emitted by XSQLServlet that is not done by JSP?
I am using software that successfully consumes generated content from a JSP OK, but the same content (using the same XML/XSL) generated from XSQLServlet is being rejected. I am puzzled by this. Maybe this is due to some differences in servlet output or an encoding issue? The content is not HTML but XML-like with an "application" contentType, like Steve's SVG example.
It seems that XSQLServlet is showing some data prior to emitting the actual content, i.e. HTTP version, responding server version, content type and date, e.g.
HTTP/1.0 200 OK^M
Server: Resin/2.0.5^M
Content-type: application/x-sky; charset=UTF-8^M
Date: Thu, 28 Mar 2002 06:45:34 GMT^M
^M
(then the generated content)
Is this preamble usually generated by a JSP also?
If not, can this information be turned off, or put another way, can XSQLServlet's raw output be set to be exactly like JSP? If not, is there a workaround?
I have tried setting the following XSQLConfig.xml
<suppress-mime-charset> for the mime-type &
<character-set-conversion>
<none/>
</character-set-conversion>
also, but to no avail.
Please help! I really want to use XSQLServlet!
Thanks.
Michael.

Yes, just less fine control over the process but the same engine.

1) Read the bytes from the servlet output stream and count them.
2) Determine the content to be sent in the response and count the bytes.

Printing to java console from servlets

Hi
i would like to use the java console on the browser to display some debugging output from my servlets.
using "System.out.println" would output to the server logs.
is there any way to do this??
-Eli-

I know that there is a Jakarta TLD that does this, it's one of the Tomcat4.0.1 examples.
<%@ taglib uri="http://java.apache.org/tomcat/examples-taglib" prefix="eg" %>
<eg:log>
Did you see me on the stderr window?
</eg:log>
<eg:log toBrowser="true">
Did you see me on the browser window as well?
</eg:log>Any visitor hitting the web site will not see the <eg:log> tags, however with the toBrowser="true" they will as well as you should see them on the console. Double check the TLDs on jakarta.apache.org to see what you can find. If you are using another Java Servlet container it's probably just a matter of changing a class file for the same functionality.
