I have centos 5.3 with Mozilla Firefox 3.5.5 and installed java jre-1.6.0_14 but when i open any web page which include java mozilla ask me that required package is missing. I have also enabled java in mozilla. What else i can check to fix this.
I opened http://www.java.com/en/download/help/testvm.xml to test my java and i got a popup window for missing plugins. The only missing plugin it show is java runtime environment.
Look at this Using the Java plugin with Firefox.
