I have windows 8 and Java 7 and office 4.0.6.2. In Tools, Options, Advanced the Oracle Corporation JRE showed up but I guess I did not realize I had to click on it in the list box. I started base and it created a database file but could not access it because LibreOffice did not know about the JRE of the Java. I went to internet explorer and enabled Java and tested it and it worked. So, I knew Java was there and worked. I have a 64 bit system, but Oracle seems to provide the 32 bit JRE with a 64 bit JRE because some browsers use that. I noticed the path in internet explorer pointed to the “bin” folder. I tried using the Add key in Options, Advanced to point to my bin folder (C:\Program Files (x86)\Java\jre7\bin) but the path shown below the list box remained unchanged as “C:\Program Files (x86)\Java\jre7”. I closed and restarted LibreOffice and went to Base and it worked properly. It allowed me to create fields and enter data. Now I am thinking the most important part was to click on the line in the list box that indicated I had the Oracle Corporation JRE, and then saving the change using the OK button, and then getting out of LibreOffice and then launching it again. On my Windows 2000 computer I have 2 older Java JRE packages and LibreOffice listed both in Tools, Options, Advanced. I selected one, restarted LibreOffice, and was able to create a database properly.
