JSP Precompilation and Servlet 3.0
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 All, Tim has just given his talk at ApacheCon NA about Servlet 3.0 / Tomcat 7.0. It was really my first taste of the 3.0 spec and I had a thought about the new features available for webapp configuration /other/ than web.xml: - - web.xml fragments - - class annotations The current method for JSP precompilation (which I've never used, mind you, so forgive my ignorance if I'm incorrect) is cumbersome: - - run the compiler - - copy the new .class files somewhere - - drop a huge load of junk into web.xml It occurred to me that that these new servlet 3.0 features could help JSP precompilation. Let's see what Tomcat 7.0's JSP precompiler could do (roughly): $ jsp-precompile /path/to/jsps my-jsps.jar $ cp my-jsps.jar /path/to/webapps/mywebapp/WEB-INF/lib (done) The precompiler could translate and compile all of the classes and package them into a .jar file for you. Great. What about servlet mappings? Well, we have two options: 1. Use annotations in the translated .java files 2. Generate a web.xml fragment and stuff it into my-jsps.jar/WEB-INF/web-fragment.xml Does anyone have any preferences? I suppose it could be an option to the precompiler, or we could even do both (do duplicate mappings conflict?). Hopefully, this will make JSP precompilation less onerous for users.

There are situations where Tomcat might be considered down and yet the JVM is completely healthy: these scenarios are not detectable by jsvc, so you'll need an additional check as well.

You're right - we should update the docs. Mark I'll give it a try tomorrow and see what it gives. By the way, my last calculation about connection_pool_size was wrong. I forgot to include the second Apache server. The math would look like this then: Apache1 - 10 server processes x 15 x 4 (tomcats) = 600 Apache2 - 10 server processes x 15 x 4 (tomcats) = 600, which makes 1200 in total Each Tomcat would receive a maximum of 300 connections, which would leave 100 free connections per Tomcat. This would solve the problem that Tomcat runs out of connections. The thing is...not all of my available Apache connections can be used: Apache has 60 threads per server process (10) - 600 connections. connection_pool_size per server process: 15. This would mean only 15 of 60 possible connections per server process can actually establish a connection to Tomcat.

I want hostname:80/tomcat-host/manager to end up at (tomcat-host) /manager for four different tomcat hosts. The forward stuff works fine, but the URLs coming back all drop the tomcat-host part. I guess reading some more documentation is in order. Some things are collected at http://tomcat.apache.org/connectors-doc/generic_howto/proxy.html#URL%20Rewriting Don't overlook the pointers for mod_proxy_html, mod_substitute and mod_sed. Most of the steps are simplified by mod_proxy using ProxyPass, ProxyPassReverse and ProxyPassReverseCookiePath, all documented at http://httpd.apache.org/docs/2.2/mod/mod_proxy.html If the response content contains URLs to fix and you can't get them fixed on the webapp side, then mod_substitue, mod_proxy_html or mod_sed can help changing the content on the fly. Of course this can get tedious if the links in the content are hard to find (and also needs some CPU resources).

Re: Any tools to detect tomcat services failure, and start it again automatically?

My env is: Solaris 10 with Apache-tomcat 6.0.29 or Jakarta-tomcat 6.0.18 Doesn't the Solaris 10 Service Management Framework provide that feature? You'd have to create an appropriate service script for tomcat though. Unforunately I only heard about the SMF from advertising, never used it myself. +1, if you primarily want to detect crashes, SMF is the way to go, at least if you like using what your platform provides. If you are looking for a more platform independent way jsvc is often used.

Re: JSP Precompilation and Servlet 3.0

I don't think the current mechanism is particularly onerous, since Tomcat supplies an ant script to do all the dirty work, including the update of web.xml. My understanding is that the ant script needs some help to get started: you can't simply run the JSP precompiler against an existing webapp without seeding web.xml, at least a bit. I suggested generating annotated java a little while back and didn't get an overly enthusiastic reception, but I like the general idea of the JSPs being in their own jar. I think it would be good if Tomcat 7.0 featured and used Servlet 3.0 functions, the source is available and it'll help users get to know the spec. p 0x62590808.asc Description: application/pgp-keys signature.asc Description: OpenPGP digital signature
Re: JSP Precompilation and Servlet 3.0
While I like the idea of using web-fragment.xml for precompiled jsp's - it would require the meta-data complete flag to be set to false which may as a side effect allow other artifacts to be loaded too. Hopefully jsp-precompile is part of the webapp build/deploy process so a developer can ignore it during development. But an admin (or release manager) can ensure that all jsps do compile before release is deployed. Setting up jsp-precompilation is a PITA the first time or 2 but once you get the hang of it, the precompilation step can be part of a standard snippet which can be pulled in via ant import.

It was really my first taste of the 3.0 spec and I had a thought about the new features available for webapp configuration /other/ than web.xml: - - web.xml fragments - - class annotations The current method for JSP precompilation (which I've never used, mind you, so forgive my ignorance if I'm incorrect) is cumbersome: - - run the compiler - - copy the new .class files somewhere - - drop a huge load of junk into web.xml It occurred to me that that these new servlet 3.0 features could help JSP precompilation. Let's see what Tomcat 7.0's JSP precompiler could do (roughly): $ jsp-precompile /path/to/jsps my-jsps.jar $ cp my-jsps.jar /path/to/webapps/mywebapp/WEB-INF/lib (done) The precompiler could translate and compile all of the classes and package them into a .jar file for you. Great. What about servlet mappings? Well, we have two options: 1. Use annotations in the translated .java files 2. Generate a web.xml fragment and stuff it into my-jsps.jar/WEB-INF/web-fragment.xml Does anyone have any preferences? I suppose it could be an option to the precompiler, or we could even do both (do duplicate mappings conflict?). Hopefully, this will make JSP precompilation less onerous for users.

Re: Connector Setting Problem in tomcat 6.0.29
Hi, Now my server.xml file is like this.As you told i added executor=tomcatThreradPool as follows Executor name=tomcatThreadPool namePrefix=catalina-exec- maxThreads=1000 minSpareThreads=150/ Connector port=8080 protocol=HTTP/1.1 connectionTimeout=2 executor=tomcatThreadPool maxThreads=1000 enableLookups=false disableUploadTimeout=true redirectPort=8443 / Still the minSpareThreads is not taken into account.
