Hi Marcel,
After looking again I tried the following change in the getParameter
method of AppletServlet.java:
public static final String getParameter(HttpServletRequest req, String name,
String defaultVal) {
if (name == null) {
return defaultVal;
}
//////////Old line////////////////////////////////////////
// Object obj = req.getParameter(name);
/////////////////////////////////////////////////
////New line
Object obj = req.getSession(false).getAttribute(name);
if (obj != null) {
return (String)obj;
}
return defaultVal;
}
In this way I can in runtime add an attribute to the session object
session.setAttribute("xmlBlaster/invalidate","false");
and solve the problem in a clear way.
Is there any other way to do it?
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 not will, the code, be changed in a future version?
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?

Marcel
Best regards,

Hi Marcel,
After looking into the code of XmlBlasterAccessRaw.java I tried to add
the following line to the applet parameters:
<param name="xmlBlaster/invalidate" VALUE="false"
/>
But the problem remains. Any tips?
Best regards,
Eduardo

I Marcel,
I take a look into the AppletServlet.java and added the following lines
just to see what was happening:
boolean invalidate = getParameter(req, "xmlBlaster/invalidate", false);
log.info(ME,"GET PARAMETER -> " +
req.getParameter("xmlBlaster/invalidate"));
log.info(ME,"GET URI -> " + req.getRequestURI());
log.info(ME,"GET PARAMETER -> " +
(String)req.getParameter("xmlBlaster/invalidate"));
log.info(ME,"GET RESULT INV -> " + invalidate);
if (invalidate == true) {
log.info(ME, "Entering servlet
doGet("+I_XmlBlasterAccessRaw.CONNECT_NAME+"), forcing a new sessionId");
session.invalidate(); // force a new sessionId
}
session = req.getSession(true);
}
And the feedback was:
[21/Dez/2005 14:35:22 INFO http-8080-Processor24
org.xmlBlaster.protocol.http.appletproxy.AppletServlet-127.0.0.1-#1req3-dummyToCreateASessionId]

org.xmlBlaster.protocol.http.appletproxy.AppletServlet-127.0.0.1-#1req3-dummyToCreateASessionId]
GET RESULT INV -> false
The page that where I use the xmlblaster applet is called like this:
<frame name="alerts"
src="../XMLBlaster/operationalAlertScreen.jsp?ActionType=login&xmlBlaster/loginName=operationalAlert&xmlBlaster.passwd=operationalAlert&xmlBlaster/invalidate=false"
scrolling="no" target="_self">
Additionally I checked in the beginning of the page the contents of the
xmlBlaster/invalidate and saw that was false.
So I'm thinking that I'm passing this parameter in the wrong way. But how can I
initialize the AppletServelet in a proper way?
Best regards,
Eduardo

Hi Marcel,
I changed the '.' to '/' but the results are the same. The data previously saved is erased.
Hi again,
please us a debugger and debug into
xmlBlaster/src/java/org/xmlBlaster/protocol/http/appletproxy/AppletServlet.java
the important parts to watch are
req.getSession(true);
...
session.invalidate(); // force a new sessionId
this code forces under some circumstances a new session,
you should see immediately what is going on,
regards
Marcel
I launch the applets page like this:
----------------------Start-------------------------------
<%
session.putValue("xmlBlaster/invalidate", "false");
session.putValue("xmlBlaster/loginName", "eduardo");
session.putValue("xmlBlaster/passwd", "secret");
%>

<title>LIAISON</title>

<frame name="main" src="" scrolling="no" target="_self">
</frameset>
<noframes>
<body topmargin="0" leftmargin="0" rightmargin="0" bottommargin="0">
<p>Esta página utiliza frames, mas o seu browser não as suporta.</p>
</body>
</noframes>
</frameset>
</html>
Am I doing something wrong? After the servelet is initialized the
others variables, for example I have a variable that stores the application
language, are changed to null.
Thanks in advanced,
And best regards to all,
Eduardo

Hi Marcel and to all XmlBlaster Team,
Thanks again for answering me so quickly. However I think I didn't put
well my question. The problem is that when starting the applet a new
object session (Browser) is created and all the data application is
lost. I think is the xmlblater servelet that changes the session
object. I read in the requirements that the xmlbaster servelet should
be called before any other servelet to prevent this kind of problems.
My question is, what should I do in order to xmlblaster applet do not
change the session object when it is initialized?
We use in AppletServlet.java this code:
boolean invalidate = getParameter(req, "xmlBlaster/invalidate", false);
Try to replace the '.' with a '/', this should help,
regards
Marcel

Hello to all,
I've developed an applet using the xmlblaster lib for applets I'm now
facing a problem. When the applet is integrated in the real
environment that uses the session object to store application data the
applet seems to create a new session object and erases all the data
that was previously stored. I have been searching in the requirements
and tried to use the following code:
session.putValue("xmlBlaster.invalidate", "false");
session.putValue("xmlBlaster.loginName", "eduardo");
session.putValue("xmlBlaster.passwd", "secret");
in order to prevent this from happening. However this didn't solve the
problem.
Can someone give me a tip how to solve this?
Merry Christmas and a Happy new year for all the xmlblaster team.
