Examples with Forms

The following examples assume you have JRE 1.6.0_11, JRE 1.5.0_12 and JRE 1.5.0_17 on your PC.

1. Modify the ORACLE_HOME/forms/server/basejpi.htm to include the new "java_version" parameter. For example add the following to the basejpi.htm:

2. Add the following to the ORACLE_HOME/forms/server/formsweb.cfg

With the two java_version parameters commented out as above, JRE 1.5.0_12 will be used since it is specified. 
If you wished to use the latest 1.5.0_X version on the PC (in this case 1.5.0_17) you could comment out all the java_version tags except for "java_version=1.5*" 

If you wished to use the latest JRE on the PC - in this case, 1.6.0_11 - then you would comment out all java_version tags except for "java_version=1.6+" 

For the Mozilla family of browsers such as Firefox, you can specify to use the latest version of 1.6.0_X on your machine with the jpi_mimetype parameter as specified above.  This feature in Firefox does not work as of 3.5.5.  A firefox bug has been created.
