David,
Thanks for the explination. I tried creating one AS400Text object with the
AS/400 early in the code. Once I did that, the table got loaded, and the
rest worked. This was much easier than trying to find and change them all.
I guess that I could complain that the Toolbox sure didn't make it clear
that was the problem, or what the solution was.

Subject: Re: Unexpected CCSID
The problem is browsers don't ship ebcdic <--> unicode conversion tables.
JDKs and most JREs ship them but browsers don't.
Toolbox does conversion by first asking the JVM to do it. Second it looks
for a table shipped with the Toolbox, and third it downloads the table from
the AS/400. If the JVM cannot convert the string and the Toolbox does not
ship the table (it contains mostly double byte EBCDIC tables that re not
practicle to download), the Toolbox can download the table from the AS/400
only if the AS400Text object is contains an AS400 object. The AS400 object
is the only 'path' to the AS/400 so if AS400Text is not given (c'tored)
with an AS400 object, it cannot download the table.
This is your case, the browser JVM does not contain conversion tables, the
Toolbox did not ship the one you want to use and there is no path to the
AS/400. AS400Text cannot convert and throws an unsupported encoding
exception. The fix is to change the AS400Text c'tors to include an AS400
object.

Subject: Unexpected CCSID
Help,
I am having a problem getting a JAVA applet to run in an IE4 brower.
I get "Unexpected CCSID returned from getBestAS400CCSID=37" when I try to
fill in an AS400Text object.
I tried to simplify the code as much as possible... here's the little
Applet:
package TestAS400;
import java.awt.*;
import java.awt.event.*;
import java.applet.*;
import com.ibm.as400.access.*;
public class SimpleAS400 extends Applet {
boolean isStandalone = false;
AS400 theAS400;
public String getParameter(String key, String def) {
return isStandalone ? System.getProperty(key, def) :
(getParameter(key) != null ? getParameter(key) : def);
}
public SimpleAS400() { }
public void init() {
this.setSize(400,300);
try {
Trace.setTraceDiagnosticOn(true);
Trace.setTraceInformationOn(true);
Trace.setTraceWarningOn(true);
Trace.setTraceErrorOn(true);
Trace.setTraceDatastreamOn(true);
Trace.setTraceOn(true);
theAS400 = new AS400("AMWUSACS");
AS400Text testingText = new AS400Text(10);
byte [] theconverted = testingText.toBytes("NickVrtis");
}
catch (Exception e) {
System.out.println(e.getMessage());
e.printStackTrace();
}
Trace.setTraceOn(false);
System.out.println("Version 1");
}
public void start() {}
public void stop() {}
public void destroy() {}
public String getAppletInfo() {
return "Applet Information";
}
public String[][] getParameterInfo() {
return null;
}
}
It works fine in the ILE.
It never even accesses the AS/400 (I do not even get the logon screen), but
that is to be expected.
When I run it from the following HTML page:
<HTML><HEAD>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=iso-8859-1">
<TITLE>Sample to test the AS/400 Text</TITLE>
</HEAD>
<BODY>
TestAS400.SimpleTest will appear below in a Java enabled browser.<BR>
<APPLET
CODEBASE = "."
CODE = "TestAS400.SimpleAS400.class"
NAME = "TestTheAS400"
WIDTH = 400
HEIGHT = 300
HSPACE = 0
VSPACE = 0
ALIGN = middle
ARCHIVE = "SimpleAS400.jar,jt400.jar"
>
</APPLET></BODY></HTML>
It does not work. I get the following from the Java Console log:

Some further debug info is that I put a few println's in to read the System
Properties.
The user.language and user.region are available within the ILE,
but I get a java security exception when I run it from the browser.
Any suggestions would be helpful... Nick
