FW: FW: [xmlblaster] session object erased????
Hi Marcel,
I've been reading the code for XmlBlasterAccessRawBase and XmlBlasterAccessRaw and I didn't see any place where the "xmlBlaster/invalidate" is initialized so even if I pass this parameter during the applet initialization this parameter is not passed to the session.
Can you take a look?
Best regards,
Eduardo Catarino

Hi Marcel,
I added the parameter in the web.xml of my application but the results are the same. I still get my object session erased and replaced by a new one.
Any other idea?
Happy new year,
Best regards,
Eduardo Catarino

I think you can set this already in
xmlBlaster/demo/http/WEB-INF/web.xml:
<servlet>
<servlet-name>AppletServlet</servlet-name>
<description>Persistent HTTP connection demo servlet</description>
<servlet-class>org.xmlBlaster.protocol.http.appletproxy.AppletServlet</servlet-class>
<init-param>
<param-name>xmlBlaster/invalidate </param-name>
<param-value>false</param-value>
</init-param>
...

If you send a patch with xmlBlaster extensions we usually add it (if it
makes sense :-)
but in this case i don't think its necessary?
