java - Maven BasicDataSource Errors on Tomcat 8 -


we started converting large webapp maven, , seemed working great, no matter do, maven doesn't recognize tomcat-dbcp.jar file on tomcat server. in dependencies, have set following:

but following stacktrace:

i should point out never problem before maven, , haven't made server side changes should cause this.

i'm using odjbc7.jar driver, date , has been installed through maven, appears in repository in correct location, , included in app via system scope. identical driver file being used in non-maven build, error not appear.

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
