iso8583

问题 I have a jpos implementation that sends and receives iso messages. It first requires sign-on before anything else. As a client, i am able to send request (customized.xml packager) and also receive response successfully with no issue. However, when the other party sends request to me, the same packager (customized.xml packager) is unable to unpack the request received. To try to resolve issue with incoming request, i decided to create a new customized packager (customized2.xml) but i noticed

问题 I came across an issue, when the jpos channel header string has spaces. I configured that in the channel adaptor configuration as below, but when I start the Q2 server, it seems it trims the header value. As a result of that, I'm not getting any response from the jpos server for certain requests. <channel-adaptor class="org.jpos.q2.iso.ChannelAdaptor" logger="Q2" name="my-channel"> <channel class="CBCChannel" logger="Q2" packager="org.jpos.iso.packager.GenericPackager" header="ISOHEADER ">

问题 In ISO message, what's the use of stan and rrn fields ? Also who will generate the these values while sending ISO messages? 回答1: STAN - usually generated by your network interface to make it unique per online message request. RRN - is the transaction related reference and can be generated by POS system, Integrator environment or the generation can be done behind the authorisation interface by the acquired/issuer systems. Depending of RRN generation side the responsibility to make it unique

问题 I'm developing a Connector with some bank, and we're using the ISO8583 protocol, right now, i'm setting the STAN(field 11) with some random number generated with a random generator but sometimes I have some number collisions, the question is, could I safely use this generator or do I need to make the STAN a sequential number? Thanks in advance. 回答1: The System Trace Audit Number (STAN) ISO-8583 number has different values and is maintained basically between relationships within the

问题 I'm trying to write a main that packs and unpacks an ISOMessage using jpos framework . The problem is that my message contains some sub_fields like field 48 , and i keep getting it as null value.
