Where is a PATH corrupted under the GNOME

[audriusb at homelan.lt]

I had to add new directory into the PATH variable. Opened /etc/profile file and
and append line to end:
export PATH=/usr/local/j2re1.4.2/bin:/usr/local/j2sdk1.4.2/bin:$PATH
Got surprise: character console shows correct PATH but GNOME terminal erases my
modifications!
I look for redefinition of PATH but found nothing.

I added lines
  PATH=/usr/local/j2re1.4.2/bin:/usr/local/j2sdk1.4.2/bin:"${PATH}"
  export PATH
to end of .bash_profile in my home directory but my PATH was redefined again!
Can anybody tell me what GNOME script makes such diverse and where I should
modify the PATH variable?
