[opencms-dev] Bean exemple

That's very noble of you! This comes from someone who has had to 
maintain OpenCms-JSPs with no less than six different languages stuffed 
into one document: Java, SQL, JSP EL, Javascript, HTML and XML. Of 
course, database resources fetched from OpenCms' connection pool were 
not released after being used. Instead the pool was reconfigured to grow 
when it's exhausted, which put an end to the annoyances caused by these 
pesky exceptions...

But I digress: what exactly is your problem? Writing and using beans 
works the same way in OpenCms JSPs as with any JSP. All you need (most 
of the time) is an instance of class CmsObject. You get that by 
instantiating and initializing a CmsJspActionElement instance (either by 
'<jsp:useBean ... />' or scriptlets) and calling getCmsObject() on it. 
Just confer the docs.
