Build errors on Solaris 2.8
When compiling Tomcat 3.2.1 on Solaris 2.8 using buid.sh, I get the
following errors. What am I doing wrong?
tomcat:

Session beans and multiple tomcat servers ?
Hi Everybody, I have a question about the architecture of tomcat and the sharing of beans (typically accessed by JSP page code) with a scope of "session". It seems to me that one major problem with JSP and session-scoped beans on tomcat (and possibly other servlet engines ? i'm not trying to bag tomcat specifically here !) is that I am restricted to a hardware architecture of a *single webserver* running tomcat. If I wish to run a 'load-balanced' (dns round robin most likely) server configuration with multiple instances of tomcat sitting behind the same URL, is there any known way in which to share session-scope java beans created by one tomcat server across the other servers ? The only way I can see to solve this problem is to push all session information to a backend database accessible by all the webservers, and to look up the session information from the database *each* time the user moves from page to page (and potentially across tomcat servers). This seems kludgy, and the database access requirements defeat both the simplicity of the session-bean approach, and add overhead to the very scalability and performance that you're trying to achieve by using multiple servers. Any guidance or relevent experiences much appreciated ... Thanks in advance. David Peterson - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
