Hi Jim

thanks for your reply ;

I'll assume you already checked to see that the same versions of Java were
loaded and the Java group and all the PTFS are at the same level?
I will also if the customer Ibm run 7.2 and my Ibm i run 7.1 ..
in our V7.R1 we have SF99572 PTF Group installed 27; i have check this in the Ibm i customer ? true ??
do you which is the lasta cumulative for V7R2 ?

You've checked to be sure you are invoking the correct Java version?
(Classpath?)
I will do

IBM i has a packet filter (not really a firewall) but I will assume it's not
being used because outside of myself and a dozen other folks, I don't know
anyone who would set it up. You might check (use Navigator for that) to see
if there are any directives in there but it's highly doubtful.
for this i mean firewall like razlee (https://www.razlee.com/) or similare that add exit point for avoid dangerous connection
Thanks

I will inform about PTF

Oggetto: Error running Java program


Hi all

i'm new in this forum and i new in Java; i have installed a program in our Ibm i and it works fine. I have installed the same program in another Ibm i (customer Ibm i) and when i run it i receive this error:


com.ibm.as400.access.ConnectionDroppedException: Connection was dropped unexpectedly.

at com.ibm.as400.access.DDMDataStream.construct(DDMDaraStream.java:92)

at com.ibm.as400.access.ClassDecoupler.constructDDMDataStream(ClassDecoupler.java:281)

at com.ibm.as400.access.AS400ThreadServer.run(AS400ThreadServer.java:361)

at java.lang.Thread.run(Thread.java:785)


can some one help me understand whic could be the problem


it seem that when the Java program try to open/read a Ibm i file (PF-DTA) go on error ...


possible caused from authorization or some Ibm i Firewall ??
