Class java.sql.DriverManager was not found

[aghasemi]

Hi,

I know it may be too far-fetched, but does anyone have an example of using an embedded, pure Java SQL engine with TeaVM. I tried SqlJet and HSQL: One failed in optimising by TeaVM, and the other becase DriverManager class does not exist. Is there a working example somewhere?

Thanks

Sure, DriverManager is not supported by TeaVM. What do you mean by "failed in optimising by TeaVM"?

trying to run a more complete example,

var db = SqlJetDb.open(SqlJetDb.IN_MEMORY, true);
        db.getOptions().setAutovacuum(true);
        db.beginTransaction(SqlJetTransactionMode.WRITE);
        try {
            db.getOptions().setUserVersion(1);
        } finally {
            db.commit();
        }

yields:

The first error is expeted - as I already explained, TeaVM does not cover entire Java class library, and the library you are trying to compile uses these methods. The second one is a bug that causes TeaVM to crash.

Anyway, you don't have any quick solutions. Here are your options:

1. You somehow convince me to prioritize implementation of missing classes/methods (donations are also ok, but here it would be really big one)
2. You get any available JS library which implements SQL and write bindings to it - I think it's a better option, becase it will rely on IndexedDB, which already implement some significant part of a DB engine.

Certainly getting something like DuckDB-WASM to work is a better option. Thanks!
