Re: Apache+Tomcat
Yoo, If you need PHP than standalone tomcat is not an option you want, to my opinion! Greetings O.

Scenario 2 is easier to implement, there are fewer things that can break and less config files to maintain. Scenario 1 gives you a unified setting of your web space. You just simply know that you have one front-end, Apache. In that case Apache receives the initial HTTP request and can handle parts of it. The most interesting aspect of such a setup are authentication and redirection. While Tomcat has some rudimentary aliasing, Apache is superrior when it comes to URL rewriting, redirections and proxying. On the field of authentication, Tomcat supports HTTP-Basic, HTTP-Digest and SSL-based authentication. Apache can add to that SPNEGO (Kerberos5, read Microsoft Active Directory Service), plus several backend mechs for the Basic and Digest (LDAP, MySQL, PostgreSQL,...). Tomcat can only benefit from that. My advice to you, if you're learning or experimenting, use Tomcat StandAlone. If you're thinking production, gather your requrements and see what fits you best. It could again very well be TC standalone.

Re: Want to run servlets from other directory than webapps
Yoo, Do you use tomcat stand-alone? Or with Apache Putting a context in server.xml should work, but this is not the prevered way in tomcat 5! Greetings O.

What do I need to do to run servlets from my user directory (e.g. /home/user/myapp)? I've tried to use http://localhost:8080/admin to add an additional context, setting path and docbase to /home/user/myapp, but this doesn't work. I've also tried to change appbase to /home/user/myapp in conf/server.xml, but again no success. I've uncommented the 'invoker' lines in conf/web.xml - for the moment anyway: servlet servlet-nameinvoker/servlet-name servlet-class org.apache.catalina.servlets.InvokerServlet /servlet-class init-param param-namedebug/param-name param-value0/param-value /init-param load-on-startup2/load-on-startup /servlet servlet-mapping servlet-nameinvoker/servlet-name url-pattern/servlet/*/url-pattern /servlet-mapping How do you configure Tomcat? Do you use the admin tool or do you do it manually? The admin tool works strange e.g. after deleting some context it was still in the list. Thanks!

Re: Tomcat 5 slow, it's in production, please help!
Yoo, Yes switch to jk2 is faster! set parameters in OPT_CATALINA with -server Xmx=? and Xms=? Sorry values depend on your available memory on the server, parameters could be different with your version, check or google for correct parameters, should improve performance... Another option could be your code, have a good look at it and try to optimize... Greetings O. On 5/6/05, Jeffrey [EMAIL PROTECTED] wrote: I use just mod_jk, not jk2 I believe. I do have connectionTimeout=2 set to AJP connector in server.xml Is there any performance issues with jk? Should I switch to jk2? Thanks. --- e [EMAIL PROTECTED] wrote: What JK version do you use? To quote Mladen: You are probably using prefork mpm, so there is no way to control the number of connections to Tomcat in any way, trough mod_jk. You can limit it only by setting MaxClients in the httpd.conf to the maximum number desired. Because of pre-forking mechanism each child process will eventually establish a single connection to Tomcat, thus the number of connections will rise from StartServers to MaxClients. So there are two solutions for prefork. 1. Make maxThreads==MaxClients 2. Add connectionTimeout=2 to AJP connector.

Re: Tomcat 5 slow, it's in production, please help!
Yoo, Probably you already looked at it but : 1) Make sure not to use reloadable in context descriptions. 2) Start tomcat with optimal java parameters, concerning memory heap and stack 3) Make sure that connections to database are minimal, do requery if answer is always the same...
