Re: Unable to find a javac compiler error
Tomcat needs the tools.jar(For Sun JDK) in Tomcat classpath. Usually this is placed in the TOMCAT_HOME\common\lib directory. If it is not there then copy it to there from JAVA_HOME\lib directory. Restart Tomcat and try the JSP page. rgds Antony Paul On Mon, 18 Oct 2004 17:38:07 +0200, Andrea Mennini [EMAIL PROTECTED] wrote: Hi, I'm trying to run this silly hello.jsp, just to be sure tomcat 5.0.28 is running under win2k: === !DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.0 Transitional//EN !-- Simple HTML file to test server setup and configuration.

Well, did you start tomcat from a console (DOS command line) which was open already before the installation of Tomcat and or Java ? Then maybe the environment variables JAVA_HOME/CATALINA_HOME were not available (although already set/defined) when starting tomcat... BTW, you are sending mails to the mailing list with a request for reply (Return Receipt). This is somewhat annoying, because you have to click that dumb message away.

No. After the install I rebooted (under windoze it's the best way to ensure that all is set up) BTW, you are sending mails to the mailing list with a request for reply (Return Receipt). This is somewhat annoying, because you have to click that dumb message away. I at least wouldn't send such a reply to newgroup postings. Yes, you're right and my apologizes for this. Anyway, I didn't mind it too much (but I'll do in the future) because usually mailing lists are set up to filter reply requests. I set it on by mistake but, if I would get from this list some valid email address to spam, it could be a good way to do it.

Re: Unable to find a javac compiler error
Do you have a full j2sdk or just a jre? You will need a full j2sdk (unless you are using tc5.5+). If so, is your JAVA_HOME evironment variable pointing to it?
