Subject Beta rc - Unpacked WAR and axis.attachments.Directory param
Date Mon, 11 Mar 2002 10:29:24 GMT
Im now working with the beta rc and have ported my app from alpha3 without
too much difficulty.

However, since I am deploying to weblogic6.1, I encountered a slight problem
with configuration initialisation.

If I don’t define the axis.attachments.Directory init param in web.xml for
the AxisServlet, an exception is thrown in DefaultAxisServerFactory:

java.lang.NullPointerException
	at java.io.File.<init>(File.java:180)
	at
org.apache.axis.server.DefaultAxisServerFactory.getServer(DefaultAxisServerF
actory.java:112)

	at weblogic.kernel.ExecuteThread.run(ExecuteThread.java:120)

This is due to the fact that if the init param is not set, getServer()
attempts to use environment.get("servlet.realpath")
to specify a directory in which to place large attachments. Since my WAR is
unpacked, the real path is null. I assume this would apply to other J2EE
containers that don’t unpack WAR's too. Maybe no fix is required for this,
but a note to include something like:

	<!-- If this is not present the attachments directory is specified
    using the Real Path - which will be null in an unpacked WAR -->
    
    <init-param>
	      	<param-name>axis.attachments.Directory</param-name>
	      	<param-value>/tmp/attachments</param-value>
	      	<description>Mail attachments directory</description>
    </init-param>

may help.

Cheers

Adam
