Simple way to run sqlplus script from java

I've got sql file that contains sqlplus specific script: it includes / or ; as statement terminators, EXEC to execute stored procedures, etc.

I need to execute this script from java (jdbc) without the need for sqlplus.

sql ant task / maven sql plugin can't handle the different terminators or EXEC commands.

Do you know any good way to do so without running sqlplus ?

We've bumped into the same problem... In brief, there are no ready solutions for that: if you open Ant or Maven sources, you'll see they are using a simple regexp-based script splitter which is fine for simple scripts, but usually fails on e.g. stored procedures.

There are indeed ANTLR parsers for PL/SQL, such as Alexandre Porcelli's one—those are very close, but still not ready to be used as a drop-in solution.

We ended up writing yet another ad hoc splitter which is aware of some sqlplus commands like / and EXIT— it's still ugly, but works for most of our scripts.

I can think of two options. One you don't want - to Runtime.exec() it to sqlplus. The other is to read in the file removing end of line slashes and sending to JDBC when you hit a semicolon. Or adding to a batch when that happens to reduce trips to the database.
