Hi! I deleted the thread but hope to say something useful Today I download data mining extension for SqlDeveloper and get the same kind of warnings as mentioned earlier Solution is: 1. install extension 2. extract from SQLDEV_HOME/jdev/extensions/oracle.dmt.dm4j.extension.codegenerator.10.1.3.jar#meta-inf/extension.xml 3. change classpaths in classpaths tag to correct syntax ("/" instead of "\") 4. copy changed file to SQLDEV_HOME/jdev/extensions/oracle.dmt.dm4j.extension.codegenerator.10.1.3.jar#meta-inf/ 5. run SqlDeveloper with DataMining extension Best regards Remigiusz I hope it doesn't violate any property rights ;-) -- --------------------------------------- Remigiusz Sokolowski <rems@xxxxxxxx> WP/PTI/DIP/ZAB (+04858) 52 15 770 MySQL v. 4.x Oracle v. 10.x --------------------------------------- -- //www.freelists.org/webpage/oracle-l
