Re: Help Please: Starting Tomcat using channelUnix with mod_jk2

[Mark Eggers]

Pascal,

I've been trying the same thing with Redhat 9, and
getting a similar problem.  I even put
/home/apache/lib in /etc/ld.so.conf and ran
/sbin/ldconfig -v.  I verified that that shared
libraries are indeed loaded.

I also tried modifying /home/tomcat/bin/catalina.sh to
include a -Djava.library.path=[various things], but
that failed to work as well.

I'll think about it some more tomorrow.

One thing to note:  In the source code, there has been
a recent change from apr_MD5FINAL to apr_md5_final. 
I'm wondering if the propagation has made it all the
way through.

/mde/
just my two cents . . . .

Hmm... Mandrake ? Not sure if my write-up will help, but you can refer to :
http://www.cymulacrum.net/tomcat/tomcat_mod_jk2.html
Be careful ! I have not tested out the configurations inside with 
anything other than Red Hat 8, and remember to back up ALL your current 
configurations before changing anything : i.e. httpd2.conf, 
jk2.properties, workers2.properties, mod_jk2.conf. YMMV!

Re: Sun JVM vs. JRockit

[Bill Barker]

Yeah, well, I've got a lot of pages like:
   
  SomeName
   /some/path/somefile.jsp

And TC 4&5 don't look at the conf/web.xml settings in this case.

Hi,

You know, there is a flag in tomcat/conf/web.xml on the jasper config :


enablePooling
false
   

So you shouldn't need to disable tagpooling in tomcat source before
compiling it.

I've always had a problem with tagpooling and using the osCache
(www.opensymphony.com) library. For some reason it does not work correctly
with tomcat, so I have to disable tagpooling too.

Re: what's an MBean and why won't my AJP13 listenere work?

[Bill Barker]

To answer your original question:
1) An MBean is a JMX manageable object.
(http://java.sun.com/products/JavaManagement/)
2) As Tim has pointed out, the Ajp13Connector is deprecated in TC 4.1.x.  As
a result, it doesn't have an MBean defined for it, since the admin webapp
won't allow you to configure it.

Solutions:
1) Follow Tim's advice and use the CoyoteConnector (my recommendation also).
2) Remove (or comment out) the ServerLifecycleListener in server.xml (this
means that you can't use the admin webapp at all).

Repost: Jk2 - BAD packet signature

This is a repost as I am starting to pull my hair out. I've still not
resolved this problem. As mentioned below whenever I try localhost:8009 I am
getting a bad packet signature. One thing I didn't mention before, though,
was that I have embedded tomcat into JBoss 3.2.1 (not sure this makes a
difference though).

Desperately seeking help.

Any help would be greatly appreciated.

Getting JK2 to work with Apache 2.0.46

[Rick Salsa]

Hi all,
 
I'm trying to get mod_jk2.so working with Apache 2.0.46 on Mandrake
Linux. I'm using mod_jk.so-ap2.0.46-rh72 and jk_jnicb.so-rh72 that I
grabbed from
http://jakarta.apache.org/builds/jakarta-tomcat-connectors/jk/release/v1
.2.4/bin/linux/. Both of these are installed in apache's modules
directory. I've got the following in httpd.conf:
 
LoadModule jk2_module  modules/mod_jk2.so
 
When I run apachectl configtest, I get:
 
Syntax error on line 47 of /usr/local/apache/conf/httpd.conf:
Can't locate API module structure `jk2_module' in file
/usr/local/apache/modules/mod_jk2.so:
/usr/local/apache/lib/libapr-0.so.0: undefined symbol: jk2_module
 
If I change jk2_module to jk_module, it doesn't give an error, but when
I try to use a JkUriSet, I'll get an error there. Anyone have any ideas?
 
Thanks!

RE: Connectors mod_webapp vs mod_jk2

[Ronnie Tartar]

Is there any way of setting the appbase on the connectors for jk2?  I would
like to try and get away from mod_webapp, since development has ceased on
it, but I want to use virtual ssl hosts without having to add the webapp @
the end of the url?  I attempted mod_rewrite, but had some issues there and
some conflicting stories on weather it worked or not? 

I'm not really a programmer, I'm an operations guy who has to host a lot of
these and need an effective way of doing so.  I know that I can use multiple
tomcat instances but would rather not.  Any suggestion would be helpful.

Thanks in advance.

I successfully implented the mod_webapp connector, thanks especially for the
document on:

http://www.codesta.com/knowledge/technical/tomcat_warp_apache/page_01.jsp

But I could not successfully install the mod_jk2 connector with multiple ssl
vhosts (IP Based). I did get it working with the default install so the
compile and code is right, I think I may just be missing something in the
config, either apache or tomcat.

Is there a way to use the mod_jk2 connector with the following
configuration, especially the appbase parameter?  Also, is there a way to
map the connectors onto the vhosts in apache?

I've done symbolic links, set environment variables, and everything else I

Hi,

I think I would have heard about it before if it was, I used 4.1.12 for
production for many months on a loaded server, with out ever seeing that
problem.

My guess is that you do Thread.sleep() or something in that way in your
application, or every request takes a very long time to execute.

You can increase the amount of threads in tomcat by editing server.xml
(where you specify the connector you use).


Hope it helps

allowLinking and Warp Connector

[Thomas . Rimmele]

Hello everybody,

We are using Tomcat 4.1.24 and our Webapps are accessed via a symbolic link.


Thus I had to configure my Contexts with a the allowLinking option:




This worked well if I connected via Http to Tomcat.

But when I tried to connect via a warp connection, the web.xml was not
found. (the typical "allowLinking=false"-error)

I tried to define the warp connector within a separate service and defined
the contexts in there.

And I tried to define the connector within the standard service that already
worked... No Way.

Was anybody able to enable allowLinking together with the Warp connector?


Greethings, Thomas

I am guessing that you do not have a mapping on the invoker servlet in
web.xml

Open the /tomcat_home/conf/web.xml  and
Unremark the block that mapps the invoker to /servlet/*

Hope it helps

isapi_redict

[Mauricio Hernandez]

Hi to all , I just started with java and got a problem about it, I'm running Tomcat 
4.1.24 under Win2k Adv Server. and  I need the following DLL isapi_redirect.dll , to 
make it work with another software, but I can find only this dll for v3.3 Tomcat,  As 
I was surfing the web I can create my own isapi_redirect but I need to have installed 
Visual C++ Ver.6.0, and don't want to install the whole package just to create it, my 
question is, If is there any light software to create it or can I use the dll for v 
3.3... whould be a problem with version 4.1.24 or is there any place where I can find 
this file for v 4.1.24 ..?

Thanks for all your help

Re: tomcat 5 won't compile my jsp

[Tim Funk]

Tomcat5 precompiles all of it's jsps during the build of tomcat5.

So if you change any jsp shipped with tomcat you will either need to
A) Rename your change to a new file
  -- or --
B) Remove the web.xml entries which map the jsps to a particualr class

I am having a problem with tomcat5/jwsdp-1.2.
Tomcat doesn't take into account changes made to jsp. If I delete the
generated java file and the class file compiled from it, Tomcat won't
translate(jsp->java) it and compile (java->class) it.
The specific file I am having a problem with is
jsp%jwsdp_home%\webapps\jsp-examples\jsp2\el\implicit-objects.jsp
Please help.

RE: Problem executing Servlets with Tomcat 4.1.24

[Reynir Hübner]

I am guessing that you do not have a mapping on the invoker servlet in web.xml

Open the /tomcat_home/conf/web.xml  and
Unremark the block that mapps the invoker to /servlet/*

Hope it helps

RE: Sun JVM vs. JRockit

[Reynir Hübner]

Hi, 

You know, there is a flag in tomcat/conf/web.xml on the jasper config :

 
enablePooling
false
   

So you shouldn't need to disable tagpooling in tomcat source before compiling it. 

I've always had a problem with tagpooling and using the osCache (www.opensymphony.com) 
library. For some reason it does not work correctly with tomcat, so I have to disable 
tagpooling too.

RE: All threads are busy, waiting

[Reynir Hübner]

Hi, 

I think I would have heard about it before if it was, I used 4.1.12 for production for 
many months on a loaded server, with out ever seeing that problem.

My guess is that you do Thread.sleep() or something in that way in your application, 
or every request takes a very long time to execute. 

You can increase the amount of threads in tomcat by editing server.xml (where you 
specify the connector you use).


Hope it helps

JK2 Documentation

[NormW]

Good evening All.
I have a few questions re the configuration and operation of mod_jk2 that I hope some 
better informed user may be able to answer.

1. The documentation describes setting parameters in the httpd.conf file using JkSet, 
and I have had success with worker parameters, but trying to set something like the 
config file keeps eluding me. The 'object' name usually comes from the section head 
[config], and since there is no local component name one expects the setting would be:
   JkSet  config.file conf/
However when I start apache2 the following error is generated depending on the form 
used:

[Fri Jun 06 20:08:31 2003] [notice] mod_jk2: Unrecognized option config:file 
conf/workers2.properties
[Fri Jun 06 20:17:55 2003] [notice] mod_jk2: Unrecognized option config.file 
conf/workers2.properties
[Fri Jun 06 20:43:03 2003] [notice] mod_jk2: Unrecognized option config:.file 
conf/workers2.properties
[Fri Jun 06 20:45:28 2003] [notice] mod_jk2: Unrecognized option config:file 
${serverRoot}/conf/workers2.properties

Can someone enlighten me please?

2. The documentation indicates all objects have three standard properties, namely 
'disabled', 'debug' and 'version', yet when 'version=0' is included in 
workers2.properties under, for example, ajp13, mod_jk2 reports it as an unrecognised 
option. Which is correct, the module or the documents?

3. The basic premise of load balancing is understandable but not the method by which 
mod_jk achieves it.  If two workers have the same lb_factor of 1, does that imply 
every second (unique, assuming sticky sessions) request goes to each Tomcat?  ... and 
if the lb_factor is raised to 5 each? 5 to one then 5 the other?
If one Tomcat has an lb_factor of 20 and the other 2, does one do ten times the 'work' 
and if so how is this 'measured'? ...over a period of time, by counters, by preference?

I've read mod_jk2 is still a work in progress but hope the questions might provide at 
least a few ideas for inclusions.
Thanks in advance for any reply,
Norm

Re: JDBC and MS Access DB connectivity.

At 09:26 PM 6/5/2003 +0100, you wrote:
I'm trying to use DataSource objects (eventually connection pooling) with MS

My question is, do we have to have an ODBC-JDBC Bridge driver in place in

to create connections to the database.
If so, where do I get this jar file for the driver?
JDBC-ODBC bridge comes AFAICT as part of the JDK.  HOWEVER, don't 
[emphasis] use it for production use.  And I even doubt if the default 
bridge implements javax.sql.DataSource  [Can't verify, but since it 
doesn't even do Metadata for tables, I'm dubious about it ]
If you MUST use production JDBC to ODBC  then perhaps try something like 
Easysoft's drivers. {Commercial}

[I haven't tried it myself... but they advertise a 'production quality' 
bridge, and I've at least used their InterBase ODBC driver with success]

You need to have libapr on your LD_LIBRARY_PATH when you start Tomcat.
