Unpacking issue while receiving iso response

Hi 

Please find below an issue we have faced using jpos 1.4.0. FYI:
Upgradation to 1.6 is currently not an option.

Question:We are facing an issue while unpacking an iso response:

This approach uses, Creating an iso object,packing it to get the
bitmap, convert the bitmap to a hex string, open a socket and send it
out. Upon receiving the response from the same socket read the bitmap
and unpack into an iso object.

We are able to send the message to the server and the server is able
to read our request. However, the response from the server cannot be
unpacked by us.

Also this approach is not scalable, since we are using only the
packaging functionality of jpos and not the channels. Please let me
know if the same hex string (bitmap) can be sent to the receiving
server over a channel e.g. NACChannel so that jpos handles the
conversion to hexstring, packing and unpacking headaches?

Find below the code which was used to send bitmap (hex converted) over
a TCP socket.

// Creating the ISO object
ISOPackager packager = new BASE24Packager();
ISOMsg iso = new ISOMsg();
iso.setPackager(packager);
iso.setMTI("0210");

SimpleConfiguration and system properties

Hello,

I have a suggestion which I think could improve the current
jPOS-EE/QBean configuration scheme.

When I deploy a jPOS-EE application it usually goes through three
different environments: development, staging and production. With
the current configuration scheme this means that I have to modify
the QBean XML configuration files for each environment. I would
like to avoid this, and would prefer to have a single unix-style
configuration file on each environment instead. 

I recently came across the Jetty webserver and noticed how system
properties is used in jetty configuration files.

Snip from http://jetty.mortbay.org/jetty5/tut/Server.html

  <New class="org.mortbay.http.SocketListener">
    <Set name="Port">
      <SystemProperty name="jetty.port" default="8080"/>
    </Set>
  </New>

Using system properties this way I would be able to modify the
service wrapper to pass settings from a unix-style configuration
file to the java environment using java -Dsetting=value.

What do you think about this? I believe it would require only
minor changes to org.jpos.core.SimpleConfiguration.

implementing Space based on JDBC

Hi

I want to implement store and forward module. Our Architecture is a
SAF  module that it closely work with Oracle Database.So I decided to
search the group and I have been informed about  a class in JPOS-EE
(org.jpos.saf.SAF() ), but this class uses JDBMSpace as a persistence
layer. So my Questions:
1- Is there any space implementation based on JDBC?
2- If not What Can I do? Can I convert JDBMSpace to JDBCSpace.

Best Regards.

How To configure QSP for Several different messages

Hi All,

I am new to JPos. I am building an application which interacts with an
ISO8583 based server. 

I read how to use QSP to configure a project and I found it very
useful. I created a dummy QSP configuration for testing. Just
providing you the channel tag which I configured there

	<channel name="xmlchannel" class="org.jpos.iso.channel.LoopbackChannel"
		packager="org.jpos.iso.packager.ISO87APackager" type="client"
		connect="no" logger="mylogger" realm="channel">
		<property name="host" value="127.0.0.1" />
		<property name="port" value="8001" />
		<filter class="org.jpos.iso.filter.MacroFilter"
			direction="outgoing">
			<property name="sequencer" value="sequencer" />
			<property name="srcid" value="123456" />
			<property name="valid" value="0 3 7 11 32 41" />
			<property name="unset" value="42" />
		</filter><!--
		<filter class="org.jpos.iso.filter.XSLTFilter"
			direction="incoming">
			<property name="xsltfile" value="incoming-filter.xsl" />
			<property name="reread" value="no" />
		</filter>
	--></channel>

Now my question is this configuration seems to be valid for one type
of message. But I may have several messages to be exchanged.

Key Variant Problem

Hi All,

I received a set of test ZMKs and encrypted ZPK from a third party
processor. I was able to generate the same check digits for the ZMK
but the ZPK is the main headache. The test components are:

Component 1:    E38F D6D9 EF85 A892 F2FB FDD0 83A4 07AE
Component 2:    D008 5DBF FB37 23B9 26CB 7980 B9EA 6268
Component 3:    2029 5EBC 0B80 BF5E F7F7 8C91 2568 6D3B

Check Digits: 2D617C

ZPK: 61BA 6165 60CA E607  AE48 319D F390 533E
Check Digits: 1426

When computing check digits for the ZPK, I get a different check
value. I've used many variant values and methods but still can not get
the same check digits. Any suggestions would be highly appreciated.

Angel.

Problem with RAM memory in Windows 2003 64 bits

Hi Jpos friends: 

I am developing a server with JPOS framework and I see the following 
behavior in the server process: 

I compile a simple server ( like the JPOS Users Manual). This server 
only respondes with RSP CODE 00. That´s all what it does. I create a 
jar file and run it in windows XP 32 bits, it works fine and the RAM 
memory of the process works very well. 

I run the same process in a Windows 2003 Server 64 bits, with jdk-
6u6- 
windows-x64, but I see that the process doesn´t works very well with 
the RAM memory. For instance, I see that for every connection i send 
to this process, the RAM memory increase exponentially and doesn´t 
free the used memory. 

For example, the process in 64 bits starts with 25.000 KB and for 
every connection i send to it, the RAM memory of the process 
increments in 50 or 60 KB, but never get to stabilize, it always 
increments!!! 

1) 25.000 KB - Process Starts 
2) 25.050 KB - 1 Connection attended 
3) 25.100 KB - 1 Connection attended 
etc... 

My question is what can i do to get my jpos process working fine in 
windows 64 bits. Why the used memory of every connection isn´t 
freed?

Fwd: Needing help in representing composite data element

Dear All,

I want to ask about the representation of composite data elements in generic
packager XML file .
I know that, with JPOS there are a representations of some composite data
elements for versions 1987 & 1993 .but
I don't have the specification documents(protocol documents) for these
versions , i have only the specification document (ISO 8583:2003) and most
of these composite data
elements changed in version 2003 .
From the above , can you help me to know how i can represent the following
field in generic packager XML as an example :

Field # 34 :  Electronic commerce data , its specification in 2003 protocol
document  as follows :

*See the attached image for the specification*

NewLine character problem

Hi,
I am faced with a strange situation.
The ISO field 31 - TRN supports new line characters. In Windows, new
line is taken as two characters - CR & LF where as in Unix it is taken
as LF only. So, TRN needs to be represented with 2 extra fields in
Windows for new line characters where as for Unix processing, 1 extra
field count is needed.
My question is how to make this field OS independent so that the value
04ACRLFB be parsed correctly in Windows and Unix?
Thanks in advance.

Regards,
Suvodip
