I culdn't connect oracle datebase to java.when i compile the program it is ok. but when i clicked on sql it asked user ID and Password .so for ID i typed scott and password as tiger .but it has shown error in TNS .what exactly i did is that i have gone to control Panel>>Administrative Tools>>Data Sources in that i selected Oracle and then i clicked add button.Then Dialog box came indicating DNS and TNS names.I just typed DNS as Oracle and for TNS i clicked on the list of TNS. But it has only one name as EXPOR_CONTROL etc.and then i clicked on Testing box to verify that connection is correct or not. The testing has failed .so what could be TNS. Another important is that how to delete the Oracle version from the system.so that i can again upload oracle to the systm. Blockquote
