Pokud po instalaci nestartuje tomcat a do logu si zapise:

[2009-08-12 11:37:06] [994  prunsrv.c] [error] Failed creating java C:Program FilesJavajre6binclientjvm.dll
[2009-08-12 11:37:06] [1269 prunsrv.c] [error] ServiceStart returned 1

tak bud nemate aktualni verzi JVM a nebo vam v C:windowssystem chybi soubor msvcr71.dll (Microsoft Visual C Runtime library version 7.1 engine) Soubor si stahnete treba odsud: http://www.dll-files.com/dllindex/dll-files.shtml?msvcr71 a nakopirujte ho do  C:windowssystem

enjoy!
