directory structure in Tomcat
hi !!
(1) i read somewhere that, if the directory structure within C:\tomcat\webapps is the correct format, then , u don't need to use ANT to deploy the appliaction, u just copy the .java files in the correct location, and when u start tomcat, it will compile the code, etc. can someone show me the proper directory structure for this ?
(2) also, the webapp uses some java libraries that need to be in the classpath. is there any way to have that path added to the classpath automatically? i don';t want to tell the client that he has to set the classpath manually.
(3) one last Q, .. i want to use a .properties file from my webapp .. where should i physically place the file? i tried placing it in the same folder as the .class files, but it didn't work .. it only worked when i placed it in c:\tomcat\bin\ but i don't want to do that, becoz, what i'm trying to do is, give the client a folder, and all that is required is to place it in c:\tomcat\webapps, i don't want to tell him to manually copy a file into c:\tomcat\bin
thanks :)

But be warned, it could cause problems if you (for example) have a webapp that uses a different version of xerces or something...

hi !!
thanks for replying :)
one thing though .. i need to load the properties from a static constructor of a class .. but the this.getClass() requires an object .. how do i get around that ?
i tried something like
properties.load(new FileInputStream("../global
(the ../ is because the java file that loads the properties is within a package .. its physical location is web-inf\package\file)
but it din't work :(
thanks :)

what's a static constructor?

e.g.
--------------
// Hullo.java
public class Hullo
{
static
{
System.out.println("Hello World without main!!!!");
}
}
--------------
if u compile and then run, then, it will complain that there is no main method. but, before that, it will print "Hullo world", becoz the class was loaded into memory

// Hullo.java
public class Hullo

}
}

So, for my example, I would do:
public class SomeClass
{
static Properties properties ;
static
{
properties.load( SomeClass.class.getResourc
}
}
public class SomeClass
{
static Properties properties ;
static
{
properties.load( SomeClass.class.getResourc
}
}

The "/" at the front of "/global.properties" tells it to look in the root of the classpath, so you don't need the ".." with getResourceAsStream()
