Re: [equinox-dev] "No SessionManager" error when trying to initialize JSP in an Equinox / embedded Jetty environment

Simon:

OK that explains a lot.  Thanks for getting this ball rolling.  Any sense for how long a fix may take?  Are there are any workarounds we could employ just to get things working in the interim?  We have some flexibility with our setup, though as always the less changes the better.

Thanks again,
Vijay

Hi Vijay,

It looks like you're using the Jetty 7 integration which appears to have a bug in it. I've open a bug on your behalf here.

[equinox-dev] "No SessionManager" error when trying to initialize JSP in an Equinox / embedded Jetty environment

Sent by:

Hi:

I am embedding Jetty in Equinox and am struggling to get JSPs to work.  Note, I am trying to implement this using the extension registry (e.g. plugin.xml).  I have read a handful of threads on this topic but have had no luck tracking down the specific issue I have:

The JSP engine is able to receive my HTTP request, parse the parameters, etc., but it breaks at the point where it tries to initialize session objects for the page.  The stack trace indicates there is no SessionManager, which obviously presents an issue.  Am I incorrectly configuring the JspServlet / Equinox environment somehow, or is this potentially a Jetty-level issue (in which case I can redirect this question)?

I have included the stack trace below and am happy to send over more context based on what would be helpful.  I am new to the OSGi/Equinox world and would appreciate any pointers to help me uncover any unknown unknowns I may be dealing with.

Thanks in advance,
Vijay
