Connecting java to sql plus editor

Question

I want to open oracle sql plus editor by giving user name and password from a java program and send queries from java program to the sql plus editor to execute.

Answer 1

I have the same sort of requirements, but I don't think that SQLPlus can be used that way. The requirements stem from having scripts written by Oracle developers that SQLPlus can parse, but are hard to parse into JDBC-executable statements with Java.
In my case I have several Oracle database developers who produce SQL scripts to e.g. create and change PL/SQL, change tables, add and remove data, etc. Generally all kinds of DDL and DML. They write one master script to execute the rest of the scripts for a particular change, using SQLPlus' @[filepath] notation.
I am somehow supposed to be responsible for releasing this stuff, which would normally mean executing each master script through SQLPlus.
I am trying to figure out a way to do this automatically.
SQLPlus would be good for this as it is written to parse the scripts that Oracle developers are used to writing.
The problem is that running SQLPlus from the command line only lets you run one (master) script, and doesn't let you set up named variables. So you can't run scripts generically; you have to know which variables turn up in which scripts, which makes it impossible to run in more than one environment/schema.
If I do things in JDBC, I have to either get the Oracle developers to write their scripts as Java strings - which would lead to a lot of errors - or try to parse the scripts in the same way that SQLPlus does - which would lead to a lot of errors.
I will look at getting the developers to delimit each statement with e.g. '----------------------' which I can use to break the scripts up into separately executable statements. I doubt this will make them happy.
I may also have to look at doing token replacement to set variables.
