Piwik not tracking visit in same network

Hi, i’m trying to use piwik, i install piwik using wampserver to track my local web application created in java. When i’m the one using the web application (where the piwik and web app is running) the piwik tracks everything i do but if i use different computer in the same network i can access the web app but piwik does not track the activity. Hope someone helps me. Thanks in advance
