[opencms-dev] OCms6: webuser self-registration

[Chris Stephens]

Hi folks,

Forgive the newbie question but I am setting up a JSP where webusers  
can self-register.

It's all working fine except that if the username already exists I  
get an OpenCms error as below:

org.opencms.db.CmsDbEntryAlreadyExistsException: Error adding web  
user "elucid".
	at org.opencms.db.CmsDbEntryAlreadyExistsException.createException 
(CmsDbEntryAlreadyExistsException.java:72)
	at org.opencms.db.CmsDbContext.throwException(CmsDbContext.java:213)

	at org.apache.jasper.servlet.JspServlet.serviceJspFile 
(JspServlet.java:314)
	at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264)			

How can I catch this exception?

I've tried but my understanding of the OpenCms 6 API and Java are not  
quite there...

Thanks in advance and happy new year!
