I’m looking for an embedded SQL database for Java, with a small footprint. Something like SQLite, but it should be pure Java. So far I’ve seen HSQLDB, H2 and Apache Derby, but they’re not what could be called small footprint. Ideally, the database I’m looking for would be embeddable in a J2ME application.

Is there something like this?

    You may try http://www.jepstone.net/tinySQL/.

    Pros:

    • It is small (93k!)
    • It is embeddable
    • It uses DBF or text files files to store data, so they are easy to read.

    Cons:

    • It is an old unmaintained project
    • It is not designed to work in j2me, but since it can work in JDK 1.1.8 it won’t be hard to make it work in j2me. Of course you will have to change some code from using RandomAccessFile to FileConnection and stuff like that, but at least you wont need to mess with generics related code.
    • It is not very fast, because it does not use indexes, so you need to try and see if it is fits yuor needs
    • It is not feature complete, just gives you a small subset of SQL
