a coredump file corrupt stack, no usefull info. how can find call stack? stack shows : #0 0x04229c7a in ?? () #1 0x00921fa7 in ?? () #2 0xbfc17e04 in ??

i doing lotus notes workflow needs connect erp system, as400 search , extract data workflow. idea can possibly that? thanks!! you can use decs on domino connect as400 using scripted activity (or configure sync). therefor need db2- driver installed on domino server. other possibility use lei (that costs bunch of money, can lot more). third possibility use lsxcon- classes , write agent data. a java- agent jdbc might possible (if as400 supports access using jdbc , have appropriate driver). all solutions either need code or money buy licences... if "one time" or "manual" task db2 driver can installed on client agent run manually or in local schedule (only working if client running).
