Re: Smooth applications migration in a J2EE cluster [mod_jk]

[Anthony Vromant]

Hi all,

I would like to know if you had time to look at the demonstration of our 
prototype.


We are very interested to get your feelings about that.

Do you have ideas about our problem of testing the validity of a user 
session within mod_jk ?
We're thinking about a mechanism relying on the JMX-Adaptor of Tomcat 
that mod_jk can

invoke through the AJP interface. What's your opinion ?

Thanks.
Regards

Hi Rainer,

First of all, thank you for these informations.

Here is the HTTP link for the Flash demonstration of our prototype :
https://wiki.objectweb.org/jonas/Wiki.jsp?page=JOnASClusteringSmoothUpdateWebCluster 



I am looking at the new features provided by mod_jk 1.2.20, the 
dynamic configuration reloading is quite interesting.

We are going to bring our prototype to this new version.

In our prototype, when a new request is coming with a JSESSIONID 
cookie, a request is sent to the worker (tomcat) for checking the 
validity (we need to know whether the session is still alive).
Currently, the HTTP protocol is used for invoking tomcat rather than 
AJP. The control at the tomcat side is done through an internal 
servlet which accesses the MBean manager for getting the current 
sessions list.


Do you have any suggestion for improving that ?

Regards,
Anthony

I think I want it more than you do (who knows, though ;) ). It's still 
going to be a lot of work to have a cleanly integrated SIP impl inside 
Tomcat (+ having it be small and efficient).

   Summary: 400 Bad Request response during auto re-deployment
   Product: Tomcat 5
   Version: 5.5.20
  Platform: PC
OS/Version: Linux
Status: NEW
  Severity: enhancement
  Priority: P5
 Component: Catalina
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: [EMAIL PROTECTED]


When you re-deploy the root war file using autoDeploy="true", Tomcat sends a
response with status code 400 (Bad Request: No host matches ...).

This makes it impossible to serve a custom error document with Apache + mod_jk
since the request processing is immediately halted to guard against security
problems caused by bad requests. (See:
http://httpd.apache.org/docs/2.0/mod/core.html#errordocument)

RFC 2616 (section 10.4.1) says about status code 400: "The request could not be
understood by the server due to malformed syntax. The client SHOULD NOT repeat
the request without modifications"

The thing is, that there's nothing wrong with the client's request. It's not a
syntactical issue and indeed the client SHOULD repeat the request.

I wonder whether a 404, 500 or 503 wouldn't be more appropriate here, at least
this would allow one to serve a custom error document during re-deployments.

hi:
I have resolve this bug by edit org.apache.jasper.compiler.Parser, in 
function parseOptionalBody,after 'reader.matches(">")' , may have a blank 
character before , so must skip those blank charactor.
I saw this bug has appearance in Tomcat5.0.* , but I find this bug in 
tomcat5.5.9 ,5.5.12. The next is Parser.java source that I have edit and test 
it in Application Server automatic test collections:

private void parseOptionalBody( Node parent, String tag, String bodyType ) 
throws JasperException 
{
if (reader.matches("/>")) {
// EmptyBody
return;
}

if (!reader.matches(">")) {
err.jspError(reader.mark(), "jsp.error.unterminated",
 "<" + tag );
}

//edit by [EMAIL PROTECTED] 20061215: beacause next may be a blank 
character.
reader.skipSpaces();

if( reader.matchesETag( tag ) ) {
// EmptyBody
return;
}

if( !parseJspAttributeAndBody( parent, tag, bodyType ) ) {
// Must be ( '>' # Body ETag )
parseBody(parent, tag, bodyType );
}
}

   Summary: Jasper ignores JspServlet's 'classpath' init param
   Product: Tomcat 5
   Version: 5.5.20
  Platform: Other
OS/Version: All
Status: NEW
  Severity: normal
  Priority: P2
 Component: Jasper
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: [EMAIL PROTECTED]


JspServlet describes and reads a servlet init parameter 'classpath'.
Documentation says: 

"classpath - What class path should I use while compiling generated servlets? By
default the classpath is created dynamically based on the current web 
application."

Current behaviour is that the configured classpath is only considered if no
classpath is configured as servlet context attribute. 

---JspRuntimeContext:335
String cp = (String) context.getAttribute(Constants.SERVLET_CLASSPATH);
if (cp == null || cp.equals("")) {
  cp = options.getClassPath();
}

It seems that when running within tomcat the context attribute is usually
present and therefore the classpath from the servlet init parameter is not
considered.
