RE: FW: FW: [xmlblaster] session object erased????



Hi Michele,

 	Thanks for replying me so quickly.
      I've been looking at the code and for XmlBlasterAccessRaw.java and  AppletServlet.java the flag is xmlBlaster/invalidate and for the BlasterHttpProxyServlet.java the flag is xmlBlaster.invalidate. But the main question for me is how can I pass to the applet this parameter? I already tried configuring the 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> 


I tried to pass as parameter to the applet like the following lines

<param name="deliveredParamKeys" 				      				VALUE="protocol,xmlBlaster/logLevels,xmlBlaster/invalidate" />
<param name="protocol" 				VALUE="SOCKET" />
<param name="xmlBlaster/logLevels" 		VALUE="ERROR,WARN,INFO" />     <param name="xmlBlaster/invalidate"         	VALUE="false" />

But nothing worked.
Can you explain me how to do it?

Thanks in advanced,
Best regards,
Eduardo


PS: Did you take a look about the DB drivers question?

Hi Eduardo,
the flag is handled in the following lines: (current svn code):

XmlBlasterAccessRaw.java:86
XmlBlasterAccessRaw.java:87
./org/xmlBlaster/protocol/http/BlasterHttpProxyServlet.java:151
./org/xmlBlaster/protocol/http/BlasterHttpProxyServlet.java:152
./org/xmlBlaster/protocol/http/BlasterHttpProxyServlet.java:154
./org/xmlBlaster/protocol/http/appletproxy/AppletServlet.java:224
./org/xmlBlaster/protocol/http/appletproxy/AppletServlet.java:225

Regards
Michele
