Hi Phil,
To answer your question directly; no, in 5 you don't need (and
shouldn't have) a context entry in the server.xml for a war file (or
any webapp for that matter). Assuming the war contains a context.xml
file in META-INF, then tomcat will use that one (it will copy it to
{TomcatHome}\conf\Catalina\hostname\WarFilename.xml and use it from
there).
Hope that clears things up.
Cheers,
Patrick

Hi,
I'm new to tomcat 5.0 and the use of context seems to have changed since
4.0. I have a war that expands outside ROOT when I place it in the
webapps directory. If I place it in the ROOT directory it doesn't. I
also noticed that 5.0 doesn't use a context entry for ROOT. So my
questions are:
1. do I need a context entry in server.xml for my war in the webapps
directory?
2. if yes, is there an example?

Frank W. Zammetti wrote: Dennis Payne wrote: Frank, I'm using threads and didn't know I was vulnerable. I'm not sure vulnerable is really the right word, but I'll go with it :) Here's how I've done it. I created a class that implements runnable and call its initialize method from a servlet init method at application startup. The initialize method creates a thread and sets a low priority for it. Roughly what I do too, except that my class extends Thread and I kick it off from a Struts plug-in. Same effect though. The run method sleeps the thread and wakes it every two minutes. A processing class contains the methods that queries the database (postgres). Same here. I think I wake my threads every minute though. 1. Is this what you call a daemon thread? Nope. If you take a peak at the javadocs for the Thread class, you'll see a method setDaemon(boolean). This marks a thread as a daemon thread. The difference, if I remember correctly, is that the JVM won't shut down until all remaining threads are daemon threads. Threfore, if you spawn a normal thread, you can hold up the JVM from shutting down properly. This is in fact the situation I had... My Tomcat instance could never be properly shut down because the threads I had spawned where not daemon threads. Marking them as such solved that problem. To the best of my knowledge, being a daemon thread doesn't implicitly say anything about a threads priority. I think you could have a daemon thread set at high priority if you wanted. I suspect most daemon threads are bumped to a lower priority though, as I do. 2. Is this better done using cron? if so how do I ensure that it runs with a lower priority than my application code? Phil This is a matter of opinion, and there are some reasonable arguments for both points of view. My personal opinion is that if you have some periodic process that is going to need portions of your system, whether it's resources available in the container or shared code, as you do, then a low-priority daemon thread spawned at application startup is a good approach, assuming you write it carefully and solidly. For instance, in my case, my daemon threads do some record aging in the database, so to me it makes sense to share the same connection pool as the application itself. I also use a number of classes and functions that are part of the webapp itself, and I don't like the idea of duplicating the code for a cron job to use (sure, could just be a matter of setting up a classpath to those classes, but it's an extra dependency, and that doesn't thrill me). But, if these tasks were volatile in any way, or they had to run independently of the app itself no matter what, the cron job approach would probably be preferable. As for ensuring it runs at a lower priority than your application code, when running via cron, that's an answer I can't give you. I'm frankly a Unix newbie, more or less, so someone else out there would be better suited to answer that. I think you'd have to have it run at a lower priority than your app server, and I'm sure there's switches to set priority of jobs, but I don't know them. Frank, I also am doing record aging. I want to move records older than two minutes to a centralized server for processing. Think of it as multiple data collection servers and a centralized data processing server. I'm thinking that the daemon to schedule queries against the data collection servers should execute on the centralized server. I'm wonder if this form of light weight replication is a good practice.

Please, humour me: put load-on-startup after init-param. I believe
that's the order per the servlet spec.
Humour me, part 2: verify the method signature of your servlet's init().
A small typo makes the difference between overload and override...
Other than that, some details would be nice: Tomcat version, log
messages, what have you...
On an unrelated note: is there any reason you're using load-on-startup
instead of lifecycle listeners?

QM/Liem
thanks for your response. I place load-on-startup entry after
init-param entry but still doesn't fire init() method of my servlet at
startup.
I'm using Tomcat 4.0.6, and don't know anything about listeners. Below
is my init() method and my Tomcat startup log:
public void init(ServletConfig cf) throws ServletException {
try { System.out.println(begin PgConnectionPoolServlet init());
pool = new PgConnectionPool(org.postgresql.Driver,
jdbc:postgresql://localhost/hardwoodthunder, pcampaigne,
, 4);
} catch (Exception e)
{
throw new UnavailableException(Couldn't create connection pool);
}System.out.println(pool created);
}
}

Either override init() instead of init(ServletConfig), or call
super.init(cf) as your first line.
As the others suggested, a ServletContextListener is not a bad place to
put this time of code either.

Yoav,
I tried overriding init() and super.init(SerlvetConfig cf) as 1st line
of init(ServletConfig cf) but neither worked.
I was thinnking that I should use the init() method appraoch becasue it
is a connectionpool and I want to initially build the pool before the
application starts to use connections. In this case is ServletContext
Listener appropriate?
thanks,
Phil

Yeah, a ServletContextListener is better because: - It will be initialized before any servlets - It will be destroyed after any servlets (so you won't close the pool while something is processing) - It's not subject to recycling by the container - You don't need to rely on servlet startup order Yoav Shapira A minor additional point for those interested in porability of webapps. What Yoav cites is guaranteed in the Servlet 2.4 specifications, which applies to Tomcat 5. It is also true for Tomcat 4, but due to ambiquities in the Servlet 2.3 specifications, it isn't behavior guaranteed by the spec. A servlet container that calls ServletContextListeners after servlet initialization isn't in technical voilation of the Servlet 2.3 spec.

Unless you are load testing the code in the IDE then what advantage is there to using a pool? My current setup uses a direct connection in the IDE via DriverManager and uses the pool when deployed to TC. For me a simple if statement chooses where to get the connection.

Does anyone know what I am doing wrong? thanks, Phil CLASSPATH=:.:/usr/java/mysql-connector-java-2.0.14-bin.jar:/usr/java/jdbc7.2dev-1.2.jar:/home/catalina/jakarta-tomcat/common/lib/servlet.jar:/home/hardwoodthunder/jakarta-tomcat/common/lib/servlet.jar:/usr/java/mm.mysql-2.0.11/mm.mysql-2.0.11-bin.jar 2004-0 2-03 18:58:51 StandardContext[/ReportingSystem]: Servlet /ReportingSystem threw load() exception javax.servlet.ServletException: Error instantiating servlet class javax.servlet.http.HttpServlet at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:911) at org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:821) at org.apache.catalina.core.StandardContext.loadOnStartup(StandardContext.java:3420) at org.apache.catalina.core.StandardContext.start(StandardContext.java:3608) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:821) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:807) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:579) at org.apache.catalina.core.StandardHostDeployer.install(StandardHostDeployer.java:257) at org.apache.catalina.core.StandardHost.install(StandardHost.java:772) at org.apache.catalina.startup.HostConfig.deployWARs(HostConfig.java:502) at org.apache.catalina.startup.HostConfig.deployApps(HostConfig.java:410) at org.apache.catalina.startup.HostConfig.start(HostConfig.java:879) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:368) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:166) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1196) at org.apache.catalina.core.StandardHost.start(StandardHost.java:738) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1188) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:347) at org.apache.catalina.core.StandardService.start(StandardService.java:497) at org.apache.catalina.core.StandardServer.start(StandardServer.java:2189) at org.apache.catalina.startup.Catalina.start(Catalina.java:512) at org.apache.catalina.startup.Catalina.execute(Catalina.java:400) at org.apache.catalina.startup.Catalina.process(Catalina.java:180) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:203) - Root Cause - java.lang.InstantiationException at sun.reflect.InstantiationExceptionConstructorAccessorImpl.newInstance(InstantiationExceptionConstructorAccessorImpl.java:30) at java.lang.reflect.Constructor.newInstance(Constructor.java:274) at java.lang.Class.newInstance0(Class.java:306) at java.lang.Class.newInstance(Class.java:259) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:902) at org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:821) at org.apache.catalina.core.StandardContext.loadOnStartup(StandardContext.java:3420) at org.apache.catalina.core.StandardContext.start(StandardContext.java:3608) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:821) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:807) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:579) at org.apache.catalina.core.StandardHostDeployer.install(StandardHostDeployer.java:257) at org.apache.catalina.core.StandardHost.install(StandardHost.java:772) at org.apache.catalina.startup.HostConfig.deployWARs(HostConfig.java:502) at org.apache.catalina.startup.HostConfig.deployApps(HostConfig.java:410) at org.apache.catalina.startup.HostConfig.start(HostConfig.java:879) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:368) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:166) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1196) at org.apache.catalina.core.StandardHost.start(StandardHost.java:738) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1188) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:347) at
OFF TOPIC-incremental development
I am developing a java/tomcat/postgresql application using ant and junit. I want to deploy tested builds along with matching tables with test data in them. What is the best way to version tables and data in the database to match a war file version? thanks, Phil - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
