Subject Re: manager webapp + ant == missing files (was: Apps Deploying to wrong dir?)
Date Wed, 30 Apr 2003 22:39:48 GMT
Hi Mike,

There is not just one possible location for your WAR files (i.e. the 
/webapps directory), but there are more of them.
Maybe this is causing the misunderstanding - the identifier "appbase 
directory" relates to how you can access the application, not where it is 
actually stored.

/webapps/ would usually contain the application if you deploy it there 
manually using FTP or if you push up a WAR file which gets extracted then.
However, every application is stored by Tomcat internally as well, inside 
the /work directory. 

To create applications which are be truly portable, you have to access any 
files inside the WAR file (e.g. properties files) using myclass
.getResourceAsStream(), not using FileInputStream etc. 

If you upload a file using the manager application it stores the WAR 
beneath the manager app work directory path. Tomcat is notified of this 
"unusual" location using the docbase attribute of the Context tag:
<Context .. 
docBase="F:\tomcat-4.1.24\work\Standalone\localhost\manager\myapp.war" 
...>

I hope this helps,
Johannes

Re: manager webapp + ant == missing files (was: Apps Deploying to wrong 
dir?)






So what is telling the application to deploy it someplace else other than 
the appbase directory?  The manager documentation says it should deploy 
into the appbase directory, so I assumed that it would work as documented. 
 I'm not following why this isn't the case.

Maybe this is just due to my limited understanding of java/servlets.  ANy 
help you can give would be great, thanks.
