[opencms-dev] Réf. : Opencms with Spring

[jacek grzebyta (RRes-Roth)]

Hi again,

So nothing useful in Apache doc however I found that:
http://www.fwd.at/tomcat/sharing-session-data-howto.html

In example “How to put shared data into a Context” I found a method which have an argument ServletContext. I’d test:

class MainTemplate extends CmsJspActionElement {

public MainTemplate(ServletContext mainContext, PageContext pcontext, HttpServletRequest req, HttpServletResponse resp)  {
...
}

....
}


And further controller like

Public String getlogin(ServletContext maincontext, ....)

I’ve never tested if Cms & Spring use the same HttpSession I suppose they don’t cos thee is no general reason to do that but I don’t know ☺. Buth otherwise if I run spring stuff inside cms jsp:

 <c:choose>
                <c:when test="${jsp.springView == 'true'}">
                                <c:import url="${jsp.uri.path}"/>
                </c:when>
                <c:otherwise>
                                <p>This is no spring</p>
                </c:otherwise>
</c:choose>

?? I don’t know. And where put <% page session=”true” ... %>? In the main jsp or spring stuff loader?

Regards,
Jacek

Hi,

I am diving in Tomcat docs now but I have some idea. In the web.xml we shows to tomcat what spring beans should be loaded so maybe we can put a kind of tunnel as a bean to create. Than it could be shared among servlets. Also cms and spring are in the same context (I guess) so it must be some easy way to join them together.

Hi,
We are currently starting to use SpringMVC && OpenCms on one of our project.
We forsake to transfer data using the HTTPSession, did you already try that ?
Another Way is to consider that once Spring did is job you just send the request (sendRedirect) to opencms (and actually you had attached all your info to the request).

I am very interresting to be involve in this discussion since there no real info about that on the Internet.

I hope it helps

Hi guys,

I have problem with simple passing CmsUser to Springs` controllers. In my projects database (not cms database) I store information about curators. Since before any change inside, the curator must login through cms so the best way is just passing CmsUser from cms level to the spring. I considered:

1. using spring inside cms not as usually the parallel servlet but it makes difficulties with generating html code from views. And in that way I'll lose a lot of functionalities.
2. The most obvious way is doing as usually (parallel servlet) but it makes difficulties with passing Cms* classes to spring.
3. I found something like servlet-servlet communication but some people says it's more risky or too difficult to do it.
4. Another way is just simple serialisation. But than it must be a way to inform spring that there is some "parcel" for it.

What do you think about? What is your opinion about that? Is any other way to consider?
Thank you for help,

Best wishes,
Jacek Grzebyta
