Method Detail

instantiate

public static Object instantiate(ClassLoader cls,
                                 String beanName)
                          throws IOException,
                                 ClassNotFoundException

Instantiate a JavaBean.

Parameters:

beanName - the name of the bean within the class-loader. For example "sun.beanbox.foobah"

Throws:

ClassNotFoundException - if the class of a serialized object could not be found.

IOException - if an I/O error occurs.

isDesignTime

public static boolean isDesignTime()

Test if we are in design-mode.

This method always returns false in Personal Profile.

Returns:

True if we are running in an application construction environment.

isGuiAvailable

public static boolean isGuiAvailable()

Determines whether beans can assume a GUI is available.

This method always returns true in Personal Profile.

Returns:

True if we are running in an environment where beans can assume that an interactive GUI is available, so they can pop up dialog boxes, etc. This will normally return true in a windowing environment, and will normally return false in a server environment or if an application is running as part of a batch job.
