如何在j2me中处理大型数据库

I want to made one application that use a database of 400Mb in sqlite3. I looking for sqlite support in j2me but nothing there is a implementation of sqlite sqljet plataform independent but use the java.io.File that not exist in j2me. I think that RMS can't handle this capacity.

我想在sqlite3中创建一个使用400Mb数据库的应用程序。我在j2me中寻找sqlite支持,但没有任何sqlite sqljet plataform独立的实现,但使用j2me中不存在的java.io.File。我认为RMS无法处理这种能力。

The db is big but is only one table.

数据库很大,但只有一个表。

I looking for other format to convert the sqlite db.Database is readonly and can be a resource.

我正在寻找其他格式来转换sqlite db.Database是readonly并且可以是一个资源。

Any ideas?

You can see list of Database in J2ME in this thread at JavaRanch forum. Or you can use Perst Lite(a Java ME embedded database).

您可以在JavaRanch论坛的此主题中查看J2ME中的Database列表。或者您可以使用Perst Lite(Java ME嵌入式数据库)。

I found above links in these questions:
J2ME With Sqlite
Is there any option for local database like Sqlite for j2me - CLDC devices?

我在上面的链接中找到了这些问题:J2ME With Sqlite是否有任何本地数据库选项,如Sqlite for j2me - CLDC设备?
