Upgrade from mod_jk to mod_proxy_ajp

[Gmail User]

I am having a problem with file uploads after upgrading from httpd-2.0.5x  
to httpd-2.2.6 and from mod_jk to mod_proxy_ajp. The Tomcat version is  
5.15--for what it is worth--but that is one thing that has NOT changed. I  
am getting this error:



"Processing of multipart/form-data request failed. Stream ended  
unexpectedly"



I searched the mailing archives, but nothing seems to help.

Before I used to be able to upload megabyte-sized files; now, the only  
test that worked was 4KB (40KB file failed). I am guessing, the problem  
has more to do with change to mod_proxy_ajp than with httpd upgrade, but I  
may be wrong (a ProxyPass that worked correctly in 2.0.5x, no longer works  
under 2.2.6). Anyone has any ideas of what I have missed in change-over?  
Does this have anything to do with 8KB mod_proxy buffer?



My httpd config is trivial (?):


	ProxyPass	/	balancer://cluster/	stickysession=JSESSIONID|jsessionid  
nofailover=On


BalancerMember ajp://localhost:8009



I also tried adding:

SetEnv  proxy-sendcl1
SetEnv  proxy-sendchunked   1

then:

SetEnv  force-proxy-request-1.0 1
SetEnv  proxy-nokeepalive 1

but neither the first two nor all four settings do anything different.


Any ideas would be appreciated.


TIA,

Ed

Tomcat always sends a 302 redirect when response.sendRedirect(newURL); is 
called.  However, a lot of user-agents wrongly follow the redirect with a 
GET when the initial request was a POST.  I'm guessing that your vendor has 
some special code that is attempting to work around this.

<% out.close(); %>

The problem is that your page is writing to the JspWriter implicit object 
"out", which on the page below is buffering the first 8Kb (the default 
value) of the page before sending it to the request.getWriter().  So when 
you close request.getWriter(), you prevent the JspWriter from sending it's 
buffered output.  Also note, that you have to make certain that there are no 
characters in the file (not even a newline) after the expression <% 
out.close() %>, or you will start filling up your logs with IOExceptions.

This will tell Tomcat to tell the browser that this is all the output it 
will receive.  Unless you are doing fancy Response wrapping, your Filters 
will find out that you are done in the usual way when you fall off the end 
of the page.

That's not true either.  All you need to run Tomcat 5.5 on a 1.4 JVM is
the small compatibility kit available on the Tomcat download page.
Tomcat 5.5 works perfectly well on JRE 1.4.

Just to clarify, you can run Java programs compiled in 1.4, but the JVM
installed on the machine running the app should be 1.5 or greater.  I'm
doing that now with a commercial app we purchased (Apache Tomcat 5.5.23,
JVM 1.5.0_12-b04 but the application itself is compiled under Java 1.4
and runs just fine.

Hi Danny,

you shouldn't run tomcat 5.5.x with JAva 1.4.
It's designed to work with Java 5 and up.

Re: jsp done processing!

[Lucas Galfaso]

Hi,
  Never do a
response.getWriter().close();
  A good design would not ask you to close something that you did not
open, and this is one of those cases.
  The full response is sent when your page "releases the thread" that
is working on this request. This is, if you want to do some processing
and you want to send the response to the browser at the same time, you
have to create a new thread.

 -lg

Re: speed up the server

[Tony Anecito]

Just I need more info about where it was deployed
before it was deployed. You can not run a web app
without the container so the question might be the
differences in the previous environment and the the
one you "deployed" into.
Same questions as below but for "both" environments.
The one where it was performing better and the one
where the performance is poor or not meeting
expectations.

Tomcat and Redirects

[Dwebb]

Hi All,

I have a question about how Tomcat handles redirects.  We have a vendor
who wrote an application for us and they tell us that they always use
the same method of issuing redirects in their code.  

What we have seen is on certain requests from a WAP handset the
application will issue a redirect and Tomcat will issue it as an HTTP
302 redirect.  On other handsets for some reason these same redirects
are issued as an HTTP 200 with an embedded link that the user has to
click on to redirect.  

We believe this may be to the POST headers that the handset is sending
but haven't managed to narrow it down to which.

We would like all of these redirects to be done with the automatic 302
redirect.  

Is there any way to force these redirects to be done with the HTTP 302?

We are running Tomcat 5.5.11, Java 1.4.2_04-b05 on Linux 2.6.9-34.ELsmp

Cheers,

Danny

I assumed that files under $(catalina_home)/common do have all permissions 
granted due to 
grant codeBase "file:${catalina.home}/common/-" {
permission java.security.AllPermission;
};

But this doesn't work and also it doesn't work when I enable the permission 
explicitly for my webApp.
permission java.io.FilePermission 
"$(catalina_home)\common\lib\servlet-api.jar","read";
TC then does "Marking this application unavailable due to previous error(s)".

PS: $(catalina_home) is an absolute path on my windows machine to that 
tc-directory.

jsp done processing!

[renen]

Hi Folks,

I want to tell the browser / Tomcat that I'm done processing my JSP page
(ie, the little spinning icon in Firefox should stop spinning!). 

However, I still want to log a couple of things (duration, browser info
etc). But, the users' browser doesn't need to be tied up while this happens.

One way to do that would seem to be to call response.flush(). However,
Tomcat seems to have issues with this (google: response.flush tomcat).
Indeed, it doesn't seem to do anything at all.

The one way I did manage to communicate that I was done was to call:

response.getWriter().flush();
response.getWriter().close();

But, on certain (tiny) pages, it seems to kill all the content. Which is a
bit unfortunate!

Is there a way that I can signal to Tomcat / the browser / the servlet
filters, that my JSP page is done?


The page that doesn't render when those two lines of code are included is as
follows:

<%@ page language="java" import="za.co.oneTwoOne.web.*"
pageEncoding="ISO-8859-1"%>
<%
Session myPage = new Session(request, response);
pageContext.setAttribute("myPage", myPage);
%>


  
ProcessID <%=myPage.getParameter("ProcessID") %> took
<%=myPage.getInt("exec ProcessGetExecutionTime ?", "ProcessID*") %> ms to
serve.
  


<%
myPage.terminate();
%>


I really appreciate your input!

Renen.

Re: speed up the server

[David kerber]

The first place I'd look is the database...

tbt wrote:

Hi,

The OS is windows XP
tomcat version 6
java version 1.5

it was working very fast before being deployed. About 30 people login
simultaneously to this application. Once this happens the application is
very slow.

Your going to need to provide much more information. Like OS and
versions of tomcat, java, database etc and maybe some metrics on how
long it takes to process the requests.

Also you will want to use a profiler to figure out what part of the
app is 'taking' so long.

With out knowing such things all we can really say is...

Buy a faster machine.
Code you app so it works faster.

As I've wrote I already did it like Apache says. It works somehow but it 
collides with the virtual hosts in the mod_jk.conf.

Hi,

Try to do as Apache says and define it like this:

NameVirtualHost *:443

  ServerName devsecure.bla.com
[...]



ServerName tstsecure.bla.com
[...]


Hope it helps.

Subject: How to configure ssl vhosts in server.xml?

Hi!

I have a Apache Tomcat configuration with vhosts in Tomcats server.xml. Those 
vhost entries will be generated in the mod_jk.conf during Tomcat start.

So far so good, it works pretty good.

Now I have to configure ssl. At my first try I did that in the ssl_vhost.conf 
of the Apache:


ServerName devsecure.bla.com
DocumentRoot "/usr/local/vipsysteme/vip8/website/devwww.bla.com"
ErrorLog /var/log/apache2/error_log
TransferLog /var/log/apache2/access_log

SSLCertificateKeyFile /etc/apache2/ssl.key/devwww.bla.com_server.key
CustomLog /var/log/apache2/ssl_request_log  ssl_combined


This works too - somehow... However there is a conflict with the vhost 
definitions in my mod_jk.conf. A warning is displayed when Apache starts:

[warn] VirtualHost devsecure.bla.com:443 overlaps with VirtualHost 
devwww.bla.com:0, the first has precedence, perhaps you need a NameVirtualHost 
directive

I guess it would be helpful to implement the ssl vhosts in my server.xml. This 
should generate another vhost entry in the mod_jk.conf including the needed ssl 
properties.

The problem is, I don't know how (parameters, attributes, syntax). Please help! 
Maybe there is an example or something.

How many concurrent users do you test with, before you deploy?  30?  Or one 
developer checking the functionality using a web browser?

What happens if you use a tool like JMeter to generate a load on your test 
server that's similar to the load on your real server?  Is the test server fast 
or slow?  If the test server's fast, the issue is probably to do with the 
configuration of the production server.  If the test server's slow... my guess 
is that the issue is to do with your application :-).

Have you tried:

- Profiling your application to see whether any parts are particularly slow;

- Checking the load on the mysql database to see whether you're saturating the 
database with queries, or whether concurrency issues are limiting the 
throughput on the database;

- Running the Performance Monitor from Administrative Tools and seeing whether 
you're short of CPU (sustained CPU load over 80%), RAM (Pages/sec consistently 
high or Memory/Available Bytes consistently below 10% of system RAM) or disk 
I/O (physical disk queue length often greater than 2 per spindle in your disk 
subsystem)?  This will give you a much better clue as to where to start looking 
for the problem.

How to configure ssl vhosts in server.xml?

[Mike Schmelzer]

Hi!

I have a Apache Tomcat configuration with vhosts in Tomcats server.xml. Those 
vhost entries will be generated in the mod_jk.conf during Tomcat start.

So far so good, it works pretty good.

Now I have to configure ssl. At my first try I did that in the ssl_vhost.conf 
of the Apache:


ServerName devsecure.bla.com
DocumentRoot "/usr/local/vipsysteme/vip8/website/devwww.bla.com"
ErrorLog /var/log/apache2/error_log
TransferLog /var/log/apache2/access_log
SSLEngine on
SSLCertificateFile /etc/apache2/ssl.crt/devwww.bla.com_server.crt
SSLCertificateKeyFile /etc/apache2/ssl.key/devwww.bla.com_server.key
CustomLog /var/log/apache2/ssl_request_log  ssl_combined


This works too - somehow... However there is a conflict with the vhost 
definitions in my mod_jk.conf. A warning is displayed when Apache starts:

[warn] VirtualHost devsecure.bla.com:443 overlaps with VirtualHost 
devwww.bla.com:0, the first has precedence, perhaps you need a NameVirtualHost 
directive

I guess it would be helpful to implement the ssl vhosts in my server.xml. This 
should generate another vhost entry in the mod_jk.conf including the needed ssl 
properties.

The problem is, I don't know how (parameters, attributes, syntax). Please help! 
Maybe there is an example or something.

Cheers,
Mike

Easiest way to prevent direct access of the login page is to put it
somewhere inaccessible, like "WEB-INF/login/form.jsp".  Tomcat
authentication valves will still forward to the page, but it won't be
available to request.


It still won't prevent attempts to access the submission URL
(j_security_check) directly, which causes the 'invalid direct reference
to login form' error that has been referred to, earlier in the thread.

This is usually the result of requesting a protected page, then not
submitting the form until session timeout has occurred, after which the
original saved request may have been purged.


There's another variation, where "/protected/resource/j_security_check"
is accessed as by GET and is assigned as the url of the saved request
which on restore, produces a 404.  I've seen this in our logs, but am
not sure how it occurs.

or, put a single ROOT.war in the host you assign as the defaultHost and
have the war parse the domain name to determine the user/blogname.
