That is surprising to me. How does your code load the properties file? I'll bet you aren't even using the ClassLoader (and you *should* be). Actually i read the documentation but no where its been written that by adding resource files to $CATALINA_BASE/bin , tomcat will make them available in its CLASSPATH I don't believe it's true, so it shouldn't be in the documentation. This is weird for me to understand, if you have any thoughts on this behavior then please share else we can close this email thread Nobody should be using CATALINA_BASE/bin for anything: it's for Tomcat's bootstrap classes only. I'm fairly sure that simply dropping a file in there won't do anything at all, unless you have modified Tomcat from its original configuration. If you want something to be globally available, use CATALINA_BASE/lib or configure a shared.loader in catalina.properties. Oh, and write your code properly to load from the class path. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with undefined - http://www.enigmail.net/ iEYEAREIAAYFAlDF9qwACgkQ9CaO5/Lv0PDwQwCeKVZkWejHUXb7R2uQX92IsSi7 MyQAnjG0iuGjhZcRjDULuDKt94d+cuXr =0hHZ -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I think in Eclipse you'll have to make a subdirectory under WEB-INF/classes and copy the files there. That's unpleasant. Eclipse will include that in the build of the WAR file when you do an export. Then, just do the following in your code to reference the resource. InputStream in = this.getClass().getClassLoader().getResourceAsStream(configfile); Where configfile is the complete classpath to your resource. This is nice. It works in exploded WARs, it works in WAR files, it works in JARs. No mucking about with CLASSPATH. No polluting other applications or Tomcat with spurious application - specific resources.

If the resources are application - specific, you don't need to do this at all. Just add the files to your local application. In Maven, there's a special directory for that: src/main/resources In NetBeans, I normally create a separate package for all of my configuration files. I think in Eclipse you'll have to make a subdirectory under WEB-INF/classes and copy the files there. That's unpleasant. Eclipse will include that in the build of the WAR file when you do an export. Then, just do the following in your code to reference the resource. InputStream in = this.getClass().getClassLoader().getResourceAsStream(configfile); Where configfile is the complete classpath to your resource. This is nice. It works in exploded WARs, it works in WAR files, it works in JARs. No mucking about with CLASSPATH. No polluting other applications or Tomcat with spurious application - specific resources. This enables you to run several copies of the same web application in the same container, all with different configurations. Just search for getResourceAsStream() for more explanation.

Re: Tomcat 6.0 CLASSPATH query
Thanks Mark for your valuable suggestions. But in my project i have a requirement to share one resource/properties file across 10 applications deployed on single tomcat instance We cannot afford to add the same properties file to all archives as its contents keep changing. Another restriction which i have is that i cannot place any file under $CATALINA_HOME directories , these are read only for us. Based on afore said concerns, do you have any better way out ..please suggest.

Property files change frequently 5. $CATALINA_HOME and $CATALINA_BASE are read-only 6
Re: Tomcat 6.0 CLASSPATH query
Thanks Mark Sorry for the confusion i created related to my requirements. 5 Out of 6 requirements you stated below are correct. The last point i.e $CATALINA_BASE is writable. I can manipulate/write files to this location. So now do you have anything more to add to your proposed solution as you suggested below Thanks, Vicky On Dec 9, 2012, at 2:09 AM, Mark Eggers its_toas...@yahoo.com wrote: See at the end for a truly spectacularly bad potential solution.

2012/12/7 vicky vicky007aggar...@yahoo.co.in: Hi Guys, I have a requirement in which i need to add couple of properties files to tomcat CLASSPATH as these are needed for my application deployed in Tomcat 6.0. One strange thing is that, i need to add the all my properties files to CATALINA_BASE/bin directory else these all wont get added to Tomcat classpath. I just want to confirm that is it by design that if i want to add any properties file to Tomcat CLASSPATH then adding files to CATALINA_BASE/bin directory is the solution we have or something else we can also do ??? Please suggest Why cant we add files to CATALINA_BASE/conf directory so that it get added to tomcat CLASSPATH 1. Have you studied the docs? There is a chapter on class loaders and class paths. 2. Blindly adding the conf directory to the classpath will break logging. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: Tomcat 6.0 CLASSPATH query
Application is deployed under tomcat webapps directory . It tries to refer to application specific properties file from tomcat classpath, for that we copied it under tomcat bin directory.
