HXTT ACCESS
mobile platforms and HXTT Access

Sirs,

I have your trial version of the MS Access JDBC driver and am implementing it in a mobile Java environment (i.e. Creme Java VM from NSICOM - Java 1.3.1).

I have successfully implemented the driver and it is working in a desktop environment (i.e. Sun Java VM version 1.6). When I run the application and JDBC driver implementation on the mobile environment I get an out of memory exception.

Have you experienced this memory problem and if so, have a solution?
Do you have a less memory intensive version of the MS Access JDBC driver?

Thank you for your time,

Tim Valentine

Try maxCacheSize=16 and delayedClose=0 connection property. If you still failed, please send your mdb sample and sql sample.

I tried the above properties, also maxCacheSize=8 and maxCacheSize=4 but still got an out of memory exception (same memory size values as before). This is happening on the creation of a connection (i.e. DriverManager.getConnection(url, props)

How do I send the Access database?

Please download the latest package, you can use J2ME=true connection property. Passed test with 1536kb memory limitation.

the new package download and property setting for J2ME=true worked. I now have the MSaccess JDBC driver working in a Creme VM (JDK 1.3.1) Personal Profile environment fully accessing an MS Access database.

Where are these connection properties documented? I could not find a mention in your documentation.

Thanks.

It's at here. J2ME is the new connection property, which hasn't been added.
