IWebContextAdapter usage yields NoClassDefFoundError on NW2004s

[Former Member]

Hello,

Can anyone indicate me replacement solution for NW2004S on the following code:

((com.sap.tc.webdynpro.services.sal.adapter.core.IWebContextAdapter) WDWebContextAdapter.getWebContextAdapter()).getHttpServletResponse()

As of 2004S, this yields:

java.lang.NoClassDefFoundError: com/sap/tc/webdynpro/services/sal/adapter/core/IWebContextAdapter

Hi All,

Has anyone been able to resolve this? I am facing teh saem problme where we used taskbinder to access cookies in ep6 but now in 2004s cannot find a way around this. I also wish to link in with mss team viewer. I can of course subscribe to the event but it will not take the initial value this is why I was acessing the databag.

Any help appreciated.

The only way I've found to get around this is to place a "helper" iview on the same page as my custom application. This helper iview is a KM iview that contains javascript that reads the cookie from the teamviewer and launches an event to the web dynpro application using EPCF.

You were warned: <a href="/people/bertram.ganz/blog/2005/02/02/never-ever-hijack-internal-web-dynpro-classes-and-interfaces">Never Ever Hijack Internal Web Dynpro Classes and Interfaces</a>

Why you need HttpServletRequest in this case? Prbably same can be done with "legal" IWDProtocolAdapter class...

Valery,

Can you give me a hint where to find any information about IWDProtocolAdapter ? I couldn't find that by myself anywhere.

Thanks,

keerthi,

What's for you need HttpServletRequest?

There are some properties of this object that are returned by public WD classes (like request parameters), so probably you can solve your task without request object that is no longer available in WD applications.

Hi valery

I am using HttpServlet request and Httpservelt response, to read and write values stored in cookies. So I am wondering is there any alternative way to avoid using cookies to store my application parameter values.

Keertthi,

There is no way to read cookies in WD application. Period. Also there is no official way to write cookies, you may use deprecated IFrame control, dynamically write HTML source to it (kind of), and set cookies via JavaScript in this generated source.

The next question is why you need to read/save cookies and what type of applications involved. If this is NW04s and both applications are WD, you may share data using WDScopeUtils. Note, however, that these data is transient and do not survive server restarts (unlike cookies that is saved on client). If you must pass information between WD and non-WD applications, then it is only possible to use technique described by <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.sdn.businesscard.sdnbusinesscard?u=pyouhggpqqi%3d">maksim Rashchynski</a>, see <a href="/people/maksim.rashchynski/blog/2006/08/07/intercomponent-parameters-exchange">Intercomponent parameters exchange</a>

Hi Valery

I need to intergrate my WebDynpro app. with the MSS Team Viewer.

To do this correctly I need to read a cookie to fetch the currently selected employee.

Do you know how to do this if I can't read cookies?
