German Umlauts in Tomcat5

[Christian Traber]

Hi,

following example works with tomcat 4.1.30 but makes problems with tomcat 5.0.19 on SuSE9.1:

Client side:

	// vir.shortName = Gfüllner
	String username = URLEncoder.encode(vir.shortName,UTF-8); 
	 // == username = Gf%C3%BCllner

   HttpURLConnection huc = (HttpURLConnection) url.openConnection();

   huc.setUseCaches (false);
   huc.setDefaultUseCaches(false);
   huc.setRequestMethod(GET);
huc.setRequestProperty(Content-Type, text/plain;charset=utf-8);
...
Serlet side:

// request.getCharacterEncoding() = utf-8
String username = request.getParameter(username);
// username = GfÃ?llner
same problem with:
String username = new String(username.getBytes(),UTF-8);
// username = GfÃ?llner
Any Ideas?

Best Regards
Christian

mod_jk2 hangs?!

[Christian Traber]

Hi,

I use apache 2.0.46, mod_jk2, tomcat4.1.18 (the standard versions 
shipped with Suse 8.2).

Sometimes the apache-tomcat connection seems to hang. After restarting 
apache (or I think
waiting for a few minutes) everything works again.

There are a lot of such messages in my apache errorlog:
...
[Wed Oct 01 20:38:11 2003] [error] mod_jk child init 1 -2
[Wed Oct 01 20:38:11 2003] [error] jk2_init() Can't find child 14357 in 
scoreboard
[Wed Oct 01 20:38:11 2003] [notice] workerEnv.init() ok 
/srv/www/conf/workers2.properties
[Wed Oct 01 20:38:11 2003] [error] mod_jk child init 1 -2

[Wed Oct 01 20:38:29 2003] [notice] mod_jk2 Shutting down
[Wed Oct 01 20:38:30 2003] [notice] mod_jk2 Shutting down


Whar means [error] mod_jk child init 1 -2 ?

Please tell me if you need further information about my configuration.

Thanks,
Christian

You're missing the jk2.shm file. This file should be created using notepad or vi (depending on your OS)and placed in a folder. That folder can be determined by looking into jk2.properties in the {TOMCAT_HOME}/conf and workers2.properties in {APACHE_HOME}/conf. Or you can specify where it needs to go. Just make sure that both files point to the same place.

I have a shm file for mod_jk2 but didn't change the tomcat jk2.properties.
Does this mean I have to use the same shm file for tomcat and mod_jk2?
I thought they will just use socket for communication!?
However, I can't use the same file, because apache is in the DMZ and 
tomcat in another net segment and I can't share a disk...

Thanks,
Christian

Context Parameter not set after manager stop-start

[Christian Traber]

Hi,

I have a Context Parameter in my server.xml Context.
If I stop and start my Context with the manager-application the 
Parameter is no longer set!
Reload works.

I'm using tomcat-4.1.24.

Is this an error?

Chirstian

mod_jk2 and stickySession

[Christian Traber]

Hi!

I've configured jk2 with a loadbalancer and stickySession=1 and made
a simple Testservlet with a getSession().
I can see the JSESSION cookie in my browser but the loadbalancer
still uses all workers and not only the worker with my session.
What is going wrong?

Regards,
Christian

Good evening Christian.
Have you set the jvmRoute parameter in each Tomcat, and the TomcatID (aka
route) for each JK worker?
Norm
 

Thanks,

I set jvmRoute in server.xml Engine section and now it works.

Best regards,
Christian

I tried to debug my webapplication on my (local)tomcat with eclipse and JPDA. Both (JDK and Eclipse) seems to allow JPDA, but I always got an Failed to connect to remote VM. Connection refused error from eclipse.

 

Try the tomcat plugin for eclipse:

Re: Tomcat RMI and Eclipse

[Christian Traber]

Hi,

I had the same problem:-(
Group/Tomcat is part of the installation directory of tomcat (C:\Apache 
Group\Tomcat 4.1)
If you install tomcat in a directory without spaces is the 
directory-names, it should works!

I have this problem since tomcat4.0. Where and how can we report this 
problem?

Regards,
Christian
