I need help with an error that I'm seeing when trying to launch a web site.
I had a PC that was running Apache Tomcat v5.x. The web site that was hosted there was working fine but unfortunately, the PC had to be replaced. The new PC is running Windows Server 2012, whereas the old was running Windows Server 2003. I installed apache tomcat 8.0.24 (server). I also installed the latest Java JRE and JDK (1.8.0_60). The old PC was running JDK 1.4.2_04. I should tell you that I don't know much about tomcat nor Java. As far as the website, I just copied the folder from the old webapps directory into the same folder in the new tomcat installation. I don't know if this was the right way to do it.
I start tomcat (C:\apache...\bin\startup.bat) and all appears to start ok. I open a browser window and try to access the website. I get the error in the browser window: HTTP 500 Internal Server Error. In the command prompt where tomcat is running I see the error:
log4j:ERROR No appenders could be found for category (...[classname???]...)
log4j:ERROR Please initialize the log4j system properly.
I'm not sure what the errors mean. This was a website that was working ok on a different PC. It could be that running the new versions of tocat and java is causing them or maybe I didn't copy the website to the new PC correctly.
Does anyone have an idea?
Thanks in advance for you help.
