Hi, Jeeper752; welcome to our community!
First, please make sure you have the most current version of Norton, by visiting the Norton Update Center:
http://updatecenter.norton.com/
Once you're sure your software is current (and have rebooted following your upgrade, if it was not), try the following steps:
- Open your Norton 360 main screen
- Click Settings
- Click Firewall
- Click the Traffic Rules tab
- Click Add
- Leave Allow selected, and click Next
- Select Connections from other computers and click Next
- Select Any computer in the local subnet and click Next
- From the drop-down list, select the protocol(s) you need to use; if you don't know, try TCP and UDP
- On this same screen, select for the rule to apply only if it matches all of the ports listed below; click Add; select Individually specified ports; type 1527 in the box; click OK; click Next
- If you'd like to track when these connections are made, check the top box, to Create a Security History log entry; click Next
- Give your new rule a descriptive name, e.g., "Apache-Derby Server Rule"; click Next
- Review the settings you have chosen, and if you're satisfied, click Finish
Note that I have made a few assumptions as I composed these steps--starting with assuming, based on your description of this as a Java application, that there isn't a Windows program (.exe) for you to attach this rule to; if there is an Apache server executable in a folder somewhere on your machine, then I'd suggest you try to set this up as a Program Rule specific to it, rather than a general Traffic Rule as specified above, for security reasons. However, since it soulds like you're only using this for client machines on your local subnet--maybe even on the same machine--this shouldn't make much difference.
Let me know if this works for you; if not, there are a few more places where I made an assumprion that may or may not hold for you, and we'll try tweaking those.
V/R,
