I'm facing this situation. my company want me to make a iReport from portal, so i must using PHP/Java Bridge.
After 2 weeks learn from internet, i done with it. But to make it better, i install new version of Tomcat and it seem no problems occur.
but the next day, when i on my laptop and try to start Tomcat service, it say 'can't find tomcat.exe' and want me to run it as administrator. when i run as admin, i get a blank page when i go to http://localhost:8080/..
stuck with it, i decide to uninstall and install it back. the 'can't find tomcat.exe' problem solved and i can do my work BUT the next day (today), i have to face that problem again.
