Hello,
LOL. Seriously the Jsr301StateManagerImpl is the wrong answer. 99.99999% of the code is shared and only a private inner class contains the change. I'll figure something out.
actually, I was just kidding but nevertheless noone said that the Jsr301StateManagerImpl isn't allowed to inherit from the "plain" StateManagerImpl.
That said, I'm not sure it's the import necessarily. But I'll trace though it to see what I've got. I know that the ExternalContextUtils has the imports on the portlet classes and it loads fine in a servlet only environment. I may have to get at the class using reflection or something to prevent it from preloading.
Although I'm quite sure that the import statement causes this behaviour, you're right, that it's not necessarily true. However, the class definition somehow depends on PortletNamingUIViewRoot _directly_. As I've already mentioned, you just have to introduce an additional indirection to prevent preloading (for example by introducing a Jsr301StateManagerUtils class - just don't use a nested class).

In order to overcome this issue Scott could introduce an additional indirection so that the class Portlet..UIViewRoot will only be loaded if Trinidad is running in the appropriate environment (for example by introducing a Jsr301StateManagerImpl ;-)).regards, Bernhard On 02/20/2008 +0100, "Matthias Wessendorf" <[EMAIL PROTECTED]> wrote:Hi Scott, On Feb 20, 2008 5:26 PM, Scott O'Bryan <[EMAIL PROTECTED]> wrote:The Apache MVN website says this about providing a "compile only" library:"The scope you should use for this is |provided|.
