Update NW 7.3 to 7.5: JCO - data displaced, offset not working correctly?

[torsten_blank2]

Hello,

we update our server from 7.3 to 7.5 and migrate apps. Everything seems fine, until we test our data booking from ecc to nw. We use jco server connection, length and Offset are ok, but data are displaced and overwritten. It seems that the offset is used, but not correctly. It counts not from beginning, but from current cursor.

Example (only strings are used): first lengt is 6, second 30, third 8. the first 6 are ok (111111), the second is displaced, because he ignore the first 6 places (222222), and wrote the next 24 (222222222222222222222222) plus the 6 from the next (third) field (333333). So result is not the expected "111111" "222222222222222222222222222222" "33333333", instead "111111" "222222222222222222222222333333" "...". Hope you can understand my Problem. Any idea? Time is running out for me because of planned go live...

thx

We changed JCo2 to JCo3 and now data not displaced anymore. Another Problem we have now: deploy is not working an this time.
