javaws not work on JDK1.5 ?

[Huang wen hui]

hi,
I install jdk1.5.0-p2 from ports using jdk1.5.0-p1 as boostrap.
I got this error msg when run javaws:

#/usr/local/jdk1.5.0/bin/javaws
Java Web Start splash screen process exiting ...
Bad installation. No JRE found in configuration file: Illegal byte sequence
