Working with shared hosting on 5.5 - logging options?

2009-03-18 Thread Josh McDonald

Hey guys,

I'm working for the first time with a client that requires I deliver a .war,
and it gets deployed into a shared environment where I have no control and
can't get access to the logs. What can I do from within my .war file to get
a local copy of logs related to my application only redirected to a file
that I do have access to? I'd like to be able to get startup / shutdown logs
specific to my app as well as application logs if possible.

Any thoughts? I find documentation for logging very hard to find online if
you want to do anything remotely out of the ordinary.

Any pointers much appreciated!

-Josh

Issue in sending Request/response http headers containing Japanese charateres

2009-03-18 Thread Rajat Gupta05

Hi All,

I have a configuration where Apache(2.2) --Mod_jk--Tomcat(5.0) for my program.
Now whenever I receive request or response having httpheaders with Japanese 
charaters, those are either replaced by ??? or they are replaced by some junk 
charateres.
Please see the Japanese headers are encoded with SHIFT_JIS encoding. Is there 
are a way where we can provide this encoding inside Apcahe/mod_jk/Tomcat.

Any help would be really appreciated.

Thanks
Rajat

Re: Userdirs on an NFS share

2009-03-18 Thread Anthony PAUL


Caldarale, Charles R a écrit :


type Status report
message /~paul/test.jsp
description The requested resource (/~paul/test.jsp) 
is not available.


Does the userid Tomcat is running under have access to the file in question?  
If not, you'll always get the 404.


Hello and thank you for your reply.
By now, I'm running it with the root user (I'm testing), but the NFS 
share is mounted with the no_root_squash option.
However, from / till the public_html, all the directories have rx access 
for everybody (and the .jsp as well), so I guess the files should be 
readable. (Actually, if I remove the :8080 in the URL, the source code 
is displayed, even Apache is running under www user)



If I change the homedirectory to a local directory, 
it works fine.


What do you mean by the homedirectory?  Tomcat's?  The user's?  Your own?


I meant users home directories.
Actually, for this test, I unmounted the NFS share, then copied my own 
home directory on the local filesystem (with the same rights).


Usually, I mount the NFS share on /NFS, but for this test I did:
umount /NFS
mkdir -p /NFS/homes/paul/public_html
vi /NFS/homes/paul/public_html/test.jsp
chmod -R 755 /NFS

Then on http://server:8080/~paul/test.jsp the jsp is executed.



But this doesn't work:
Listener className=org.apache.catalina.startup.UserConfig
 directoryName=public_html
 homeBase=/NFS/homes/
 userClass=org.apache.catalina.startup.HomesUserDatabase/


Where is the above Listener located?  What does doesn't work mean?  Be 
specific.


What I meant by doesn't work is the symptom I described above: the 
Tomcat 404 error:

type Status report
message /~paul/test.jsp
description The requested resource (/~paul/test.jsp) is not available.

The Listener is in the server.xml, inside the Host. Below, the whole file:

== server.xml ==

?xml version='1.0' encoding='utf-8'?
Server port=8005 shutdown=SHUTDOWN

Re: Userdirs on an NFS share

2009-03-18 Thread Anthony PAUL


Anthony J. Biacco a écrit :

Remember that over nfs, the client's access to the server will be as
user nobody or nfsnobody, depending on your system, so that user will
have to have access to all those directories/files, unless of course you
use the anonuid/anongid directives in your exports file.

Yes, but the whole directories in my NFS share are rwxr-xr-x, so I think 
it should be ok...


/NFS (755)
/NFS/homes (755)
/NFS/homes/user (711) (but for the test, I changed it to 755)

Tomcat hangs due to socket reads?

2009-03-18 Thread Diego Manilla Suárez

Hi everyone. I'm running Tomcat 5.0.30 + Apache 2.2.3 on a SuSE EL 10. 
After a few days running, the CPU load increases, until Tomcat is eating 
99% of it, and I need to restart. The last time this happened, I 
executed jstack on the Tomcat VM, and I saw most of threads stacks are 
like this:


##
Thread 26701: (state = IN_NATIVE)
- java.net.SocketInputStream.socketRead0(java.io.FileDescriptor, 
byte[], int, int, int) @bci=0 (Compiled frame; information may be imprecise)

@bci=167, line=684 (Interpreted frame)

- java.lang.Thread.run() @bci=11, line=595 (Interpreted frame)
##

This makes me think there is some issues with Apache - Tomcat connection 
or maybe some SO configuration, because the number of requests is not 
that high.


This is the configuration of the AJP connector on server.xml:

##
Connector port=8080
  maxThreads=10 minSpareThreads=1 maxSpareThreads=1
  enableLookups=false acceptCount=100
  debug=0
  disableUploadTimeout=true /
##

And the forwarding in Apache is done through mod_proxy_ajp, like this:

##
ProxyPass /frontdipuleon ajp://localhost:8009/myapp
ProxyPassReverse  /frontdipuleon ajp://localhost:8009/myapp
##

Any idea on what can be wrong? The only thing I tried now is setting a 
connectionTimeout on the AJP connector, but I think this wouldn't tell 
me the real cause of these problems. What else should I check?


Thanks in advance.

Re: tracing port to port

2009-03-18 Thread Gregor Schneider

André,

two questions:

what type of conenction is the servlet using? Is it RMI, Socket, something else?

If you're not happy with Wireshark, there might be an approach which
takes a bit more effort but might work in case the Java-classes are
not obfuscated:

Talking RMI:

- try to decompile the Java-classes from the war (nice software to do
that might be http://java.decompiler.free.fr or simply try JAD)

- find the RMI-interfaces

- write an RMI-proxy which dumps the information using either
console-output or log4j or whatever you like

- after that, forward the RMI-information from the proxy to the Java-Demon

Cheers

Gregor

Hi.
No idea about your problem, but in the information you provide, you are 
showing the Apache connecting to port 8009 of Tomcat, but for Tomcat you 
are showing the Connector that listens on port 8080.

That's probably not very helpful.

Hi André. That was just an error when copying and pasting, I picked up 
the wrong connector. This is the right one:


##
Connector port=8009
   minProcessors=5 maxProcessors=150
   enableLookups=false redirectPort=443 debug=0
   protocol=AJP/1.3 /
##

Thanks for pointing that out.

Re: Support for JSF 2.0

2009-03-18 Thread Martin Dubuc

I can't find the JSP 2.2 specification, but if you look at JSR-316, you will
see that the basis for Java EE 6 is servlet 3.0, JSP 2.2 and JSF 2.0. I am
not sure it makes much sense to align JSP 2.1 with servlet 3.0.

RE: Issue in sending Request/response http headers containing Japanese charateres

2009-03-18 Thread Rajat Gupta05

Hey Mark,

Thanks for your response... I have tried to isolate the issue if it is being 
caused by Apache/Mod_jk/Tomcat. Firstly I tried a request to standlone apache 
with customize d header having Japanese characters. The requested page displays 
the headers in the request. To my surprise Apache is not dealing with Japanese 
characters correctly and replacing them with some junk value. For example I 
addedミが完たソ税一使饅漢社氏ｿ圧user1 in the request header and wht I received was 
~ª®½\Åêgé\¿Ð¿³user1.

Also to add the same thing works when make request to apache configured to 
reverse proxy. Can any one provide explanation to that?

Thanks
