iAS 9i r1 (1.0.2.2.) + Oracle Portal 3.0.9.8.0 Solaris 8 Oracle Database Server 8.1.7.4 Custom JSP suddenly stops working and in the custom application log we see some "strange" characters. 1. Before the problem occurred: QuerySubmissionEngine.doQuery(): results = UPPER(USER_NAME) CUSTOMER_ID 2. After: QuerySubmissionEngine.doQuery(): results = ÿþUPPER(PARTY_NAME) PARTY_ID Output from cat -vt: 1. Before the problem occurred: COADM1921^I22656^I COADM1922^I22657^I 2. After: ^@C^@O^@A^@D^@M^@8^@2^@0^@8^@^I^@2^@7^@3^@1^@2^@8^@^I^@ ^@C^@O^@A^@D^@M^@8^@2^@0^@9^@^I^@2^@7^@3^@1^@3^@1^@^I^@ The same JSP still works in developement. I've already checked iAS components environment (Apache, JVM), unix shell accounts. DB and listener - the listener on the production server is started with NLS_LANG set (in development without). I've tried to start the listener on the dev machine with NLS_LANG set and the JSP works anyway. Any help would be highly appreciated! Thanks Dimitre
