java - Eclipse Ubuntu Install Error -

i've installed jdk, , i'm installing eclipse, , error message comes :

jvm terminated. exit code=127 /usr/local/bin/java -xms256m -xmx1024m -jar /home/adrien/eclipseinst//plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar -os linux -ws gtk -arch x86_64 -showsplash -launcher /home/adrien/eclipseinst/eclipse-inst -name eclipse installer --launcher.library /home/adrien/eclipseinst//plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.300.v20150602-1417/eclipse_1612.so -startup /home/adrien/eclipseinst//plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar --launcher.appendvmargs -exitdata 50001a -data @none -vm /usr/local/bin/java -vmargs -xms256m -xmx1024m -jar /home/adrien/eclipseinst//plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar  

i don't know what's causing that.

if java in path eclipse should work directly after unzipping distribution downloaded. try again , not change anything.
