If you do not have permission to create RMI client, like setting RMISecurityManager, instead of throwing SecurityException, RmiProxyFactoryBean of spring will just return NULL to client... - http://java.sun.com/docs/books/tutorial/rmi/client.html

And there is an issue before spring 2.0rc4, The toString() method of bean will be called after bean created (finished constructor call) and before setting properties (call setter to press beans to properties). If any methods of those properties called at the toString() method, you will get NullPointerException - http://forum.springframework.org/showthread.php?p=78557#post78557

How to get instance fo nsIDownloader using javaxpcom?



It's not too difficult. The JavaScript code you pointed to has this line:

var nsIDownloader = Components.classes["@ mozilla.org/network/downloader;1"].createInstance();



The "Components" object is a helper object in Mozilla JavaScript, so we need to do things differently in JavaXPCOM.



We need to use the nsIComponentManager interface ( http://mxr.mozilla.org[..]com/components/nsIComponentManager.idl), which has a createInstance() method. So something like this:



nsIComponentManager compMgr = Mozilla.getInstance().getComponentManager();

nsIDownloader createInstance = (nsIDownloader) compMgr

.createInstance( "@ mozilla.org/network/downloader;1", null,

nsIDownloader.NS_IDOWNLOADER_IID );

cvs

If you have problem of connecting to CVS through ssh and non-standard port, please refer to http://michi.knallgrau.at/blog/month?date=200511

cvs -d :ext:michi@cvs.some.server.com:12345/opt/cvs co MyProject
But this results in the following error:
CVSROOT port specification is only valid for gserver, kserver, and pserver connection methods.
According to this posting
-> http://lists.gnu.org/archive/html/info-cvs/2004-10/msg00291.html
it seems, that it is necessary to define an ssh-Alias by adding the following lines to ~/.ssh/config:
Host SomeCvsServer
HostKeyAlias cvs.some.server.com
Hostname cvs.some.server.com
Port 12345
Then the following command will be rewarded with success:
cvs -d :ext:michi@SomeCvsServer:/opt/cvs co MyProject
