Using the JNDI

[Lars Larsson]

Hello all!

I have a problem... I am successfully using the JNDI classes to access and read/write to an LDAP directory, everything seems to be fine except writing the jpegPhoto attribute!

The problem I have is that it refuses to write the LDAP attribute as a attribute of type binary, it's only store as a text value.

I managed to save binary attribute when using some class library from Novell, but I would like to stick to the core JDK so that I'm not depending on any external libraries.

I am attaching my class if its of any help...

Thank you in advance
