Can you re-install Tomcat (without your webapp) and verify that it starts and stops without any problems? Then, re-add your webapp and see what happens. Which version of Solr are you running? A fairly stock Solr 4.2.1 does not give any such warnings when I deploy it onto Tomcat 7.0.40. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJRpNuDAAoJEBzwKT+lPKRYD8gP/0EfatV4frxZiUBW+kgD1q/U /rABJRSQmRJr4GTzXOmx+s3cA7YUOgPmkSPG6+5VGPC8zXx98+nY4LW5wFh3bUIX iWijF6xtItwZgZBU1oz4FbyOdLMwkGfnpn19DXYCkvVXiz+q/TUFWMiBbGa8nCYV zqUdONm89fvivGBzshyc2Lgg79gGk7dHiE9KIQL0xP7nU+Xm9KIDqTsla+l9uFUf Pltz0vY4w8GZJhoUrnLpG3zh2Skfc3shkLIdXw9qdIE19JjiHV6PzU8lBgC07PC+ PR+5+v9RWnm+XvgcNQXdJ0mYBAEHVSPWwRuOlE6s8ze8bYzeTmEJY3H6h1lyoXUe sFQF+wdM0Eezt+uMSYdA4tEBvsVV/eCVU8vDWUo+dF59JAPTy6iQ2TZhnaFiextp SS0/pTQAXLUdvgoJxepE5axR3yQ/XyHVz6vm2QTDZ52e9M9GOSuAQeN/lMjDIc+H r6/gWSx1vSB8J1OwE3mrDfMEGff3lLHiI7N0XqPzLYy/y+2iIarktrUmQ6BMd12c GTn4WIvkDSFAL7X0IYx5r6UMJNUT7pG5195YEMy7ZR9EEmFKXGkuk9mAGFFlAOdX hB9oWEAtn833VJlXfE7ptBc3S+uhH3GK+c08qAkRtCxyiPvPtR15ZDAy3BoLCxJY eet9M1NGijrPJFC2ObWc =vRK2 -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
