HACL for Java and Unsupported Converter
Paul Ballard
start a 5250 session. I get a message in the log that says "Unsuppored
Converter: 037" but it doesn't throw any exceptions. Just can't get a
connection and PS. Any ideas here?

applet and application using HACL through a TN3270 running on a
Communication Server 6.0. I'm trying to get the example that comes with the
documentation to work, but get the message:
"Unsupported Converter : 037"
I'm trying to connect to the Comm. Server over the TCP/IP network. The
applet/application is not residing on the same machine that the Comm.
Server is installed on.
If anyone knows how to get those HACL examples to work with Comm. Server or
Host on Demand, pls help me.

This looks like more of a security problem. Are you writing an applet
or application? What archives from HOD are you using? If you are
writing an applet, have you taken the appropriate measures to sign the
archive from HOD? The message you are seeing is basically harmless and
I would guess it is not the cause of your problem.

preferred using Visual Cafe to write a standalone .exe but needed object
libraries or source code that I couldn't find on the web. If that exists, I
would appreciate getting it.
I am using the ECL101.JAR archive. I'm not aware of any security issues for
connecting to our AS/400. I also have no idea what your a saying about
"signing the archive". I don't have any docs, just a problem and deadline!!
Welcome to modern development I guess...

Please cut and paste your ENTIRE Java Console output to this forum. Since
your're running from the command line, you may need to expand the number of
lines in your DOS window or pipe the output to a file.
Thanks,

We are curious -- are you trying to get an emulator window? If so, this is
not possible with HACL. HACL is just a way to get communications with a
host and send/receive data with that host. You have to write your own GUI
interface (emulator window).
If you are trying to get an emulator window, Host On-Demand version 3.0 has
a terminal java been that will allow you to easily create a terminal in a
frame. See the samples in the HOD 3.0 toolkit for more info.
Also, the Netscape HOD code is version 1.0 and does not have HACL
capabilities.

I have been trying to talk to our network amins about the setup of the
communication software. I was wondering. Does the IBM Host On Demand client
that is shipped as part of Netscape use the same technology as the HACL? I can
get an emulator window with the Netscape client, but can't get anything with
the HACL. Also, is there source code for that client I could look at to see if
I'm doing something wrong?

Basically screen scraping. I was able to connect, but only using VT
emulation. The Netscape version uses 3270. Is there any newer docs? I am
trying to use the WaitForScreen method of the ECLPS class and it apparently
doesn't exist or doesn't have the correct parameter list. I've found a few
errors in the docs like that.

OOOOLD jar file (relatively speaking, in web years of course). The screen
recognition calls came along in HOD 3.0. I think the ECL101.jar is an early
HOD 2.0 jar file released to the CommServer group, and thus shipped with
CommServer. There should be javadoc documentation that came with
CommServer, but I'm not sure.
Your best bet is to use a newer version of the HACL jar file (post HOD 2.0)
or even the bean jar files such as hod30beans.jar or hod30beansNLV.jar
shipped with HOD 3.0. In the meantime, can you give me the time/date of the
ECL101.jar? Also, open the jar file and tell me the date of ECLPS.class.

First - running under NS 4.5, the 5250 applet will occasionally come up
with ????? in place of the text. Here's the console after a good run, i.e.
real text:

Naturally, I can't get it to fail just now to give you that sample.
(Grrrr!) As soon as it does, I will send you one.
Second, running as an application under JDK1.1.7B, the following dump is
from my class:

... etc. ( this is an unrelated problem, I think)
Message String - KEY_NEXT_PAD: Not Found
Starting communications to myhost...
Unsupported Converter : 037
Converter3252.fakeConstructor : no matched Converter!!
-------------------
This produces a window with an emulator in it, but in place of all the
text. The code was lifted from HOD itself and modified:
-----------------
Properties p = new Properties();
p.put(ECLSession.SESSION_HOST, host );
p.put(ECLSession.SESSION_HOST_PORT, "023" );
p.put(Session.SESSION_TYPE, ECLSession.SESSION_TYPE_5250_STR);
p.put(Session.CODE_PAGE, ECLSession.SESSION_CODE_PAGE_DEFAULT);
p.put(KeyPad.SHAPE, KeyPad.S2X11);
setBackground(Color.gray);
myTerm = new Terminal(p); // Build a Terminal bean
myPad = new KeyPad(p); // Build a KeyPad bean
myPad.addSendKeyListener(myTerm);
myTerm.addPropertyChangeListener(myPad);
add("Center", myTerm);
add("South", myPad);
System.out.println("Starting communications to myhost...");
myTerm.setHost(host);
myTerm.startCommunication();
validate();
show( );
--------------
I have a similar problem when running HostLaunchPad from the HACL samples:
-----------------------
E:\HOD\lib\toolkit\hacl\samples\launchpad>java HostLaunchPad
Properties: {SESSION_HOST=209.104.143.142, SESSION_HOST_PORT=23}

Unsupported Converter : 037
Converter3252.fakeConstructor : no matched Converter!!
^C
E:\HOD\lib\toolkit\hacl\samples\launchpad>
----------------------------
In this case, the window does not come up, I think because the code has not
been converted properly from 3270 to 5250. In any event, you can see the
error. Contrary to what you have said in other replies, I don't believe
that this is benign. I think it can't always find it's codepage converter
and sometimes substitutes ?????????. What do you think?
Here is my class path:
E:\JAVA\HACL>set classpath
CLASSPATH=.\;d:\sqllib\java\db2java.zip;d:\jdk1.1.7b\lib\;d:\jdk1.1.7b\commapi\comm.jar;e:\hod\lib\hod30dbg.jar;e:\DriverAgent\JavaAgent\;

I made two changes that fixed this problem. The first was, in my code, I added some imports. I foolishly thought that, since I didn't use
these classes, I didn't need to import them. ................ wrong!
import com.ibm.eNetwork.ECL.*;
import com.ibm.eNetwork.Hod.*;
import com.ibm.eNetwork.*;
The second change was complementary -- added e:\hod\lib\ to the CLASSPATH so the compiler would find the imports just specified. Now things
work. HOD finds all its messages and it's converters and suchlike.
Why HOD, when run as an applet occasionally doesn't find it's converters is another problem, although the CLASSPATH might fix that too. I
will provide documentation on that when and if I can replicate it.

file? I don't know where the software that came with our server is, and would
be old and gray before finding it.
Regarding my files:
ECL101.JAR 11/17/97 376KB
ECLPS.CLASS 11/17/97 37KB
That is prety old. As usual, a quick reply would be appreciated.
Thanks,

package that includes these files. If you want to stick with the ECL101.jar
file, (and you bought comm server) you should contact IBM support and open
an problem record with them to get it fixed.
If you want to upgrade to HOD 3.0, I should be able to get you in touch with
the right people to make it happen.

P.S. Sorry for the delay, I've been out sick.

especially screen-scraping capabilities with 100% Java API. Also, NVT terminal
windows under JFC/Swing would be nice.
I tried to contact sales but they only think in per-cpu product licenses. Can I
just get the HACL product as a library/jar file to integrate into my
application? I don't need a gateway and a per-machine fee is cost prohibitive.
Also, I notice that support seems rather vague on this newsgroup; are the ibm
people on the newsgroup volunteers/users or do they have dirct access to the
real developers of HOD?
Can anyone please advise or refer me to the appropriate resource?
