# Preverification Preference

Select the Java ME > Preverification category from the left pane of the preferences dialog to specify preferences that control the preverification operations performed by the plug-in.

There are two fundamental issues that one controls with this dialog:

1. Whether to preverify for CLDC 1.0 or CLDC 1.1.
2. Whether to use the external preverifier, the one available on a SDK or the Proguard preverifier.
