JBoss 4.0.1 : config and properties files not found anymore

thunder Jan 10, 2005 4:53 AM

We are planning to upgrade our current JBoss 3.2.3 servers to JBoss 4.0.1 but if we deploy JBoss 3.2.3 ear files, the applications cannot find their properties and config files any more that are just sitting on the root of the application.

Example structure :

-com
---abc
------def.class
...
-a.properties
-cache.ccf
-config.xml

What are we doing wrong and how can we resolve this? The ear file works like a charm in JBoss 3.2.3 version but not in the version 4.0.1

Where do we put the config files if the root of the app is not reached any more ? Are there any best practices in JBoss?

TIA

The ear should not contain plain resources. Just put them into a jar.

Hi Frito,

First thanks for your time to reply.

Perhaps my entry wasn't clear on it, but we construct our ear files like they are supposed (?) to be.
myear.ear - myjar.jar (ejb) - mywar.war (webapp) - application.xml mywar.war - ourwebsources - WEB-INF ---- lib ---- classes -------- abc (package) ----------- def.class ----------- ghi.class -------- afile.properties -------- config.xml -------- cache.ccf

The problem is that the ghi.class f.e. needs to read the file cache.ccf to setup the cache structure ... but it cannot find it anymore in JBoss 4 like it does automatically in JBoss 3.2.3

Any ideas ? TIA

Try putting your properties/config file at the same level as the class files are (I mean try placing the xml/props file inside abc package).

Also copy paste the code that reads the config files. Then we can understand as to what you are doing and what may be wrong.

When I say copy/paste the code, please don't paste the whole Java source code. Just the snippet where you deal with the config/properties files.

Copied cache.ccf to dir of caller SecundaryCache.class : no effect still nullpointer exception.

So, here goes :

According to the the http://jakarta.apache.org/turbine/jcs/LocalCacheConfig.html the file should be placed at the root of the classpath, since it is discovered automatically, and in JBoss 3.2.3 we experience no problems finding it automatically.
