Hi,
after receiving a bug to switch biomaj-watcher to Tomcat8, I made the required updates, but my webapp has deployment error on Tomcat 8. I ask here for help to ease the switch to v8 (from v6).
I define a context xml with a docBase. I do not understand why it fails now.... any help would be appriciated to help package kept in Jessie.
My context XML is like:
<?xml version="1.0" encoding="UTF-8"?>
<Context path="/BmajWatcher" docBase="/usr/share/java/webapps/biomaj-watcher" reloadable="false" >
<Parameter name="ADMIN_LOGIN" value="admin" override="false"/>
...... (only other parameters)
Here is Catalina log:
