Where to obtain mod_jk

[Michael Timpe]

Hi,

I need a mod_jk binary for a SuSE Linux 7.3.

All the folders in the download area of the jakarta project are empty 
(release, nightly, ...)

Where can I download a stable version of mod_jk for use with Apache2.

Internal Server Error

[Michael Timpe]

Hi,

I get an "Internal Server Error" very often after an idle time of some 
minutes. What can I do?

Platform:

- Win NT / Win 2000
- Apache 1.3.26
- mod_jk
- Tomcat 4.0.3

(P.S.: on a linux system it is stable and we have no problems! This 
error occurs only on Windows machines).

Greetings

Michael

Re: Is CLASSPATH ignored ?

[Michael Timpe]

There is a way to use the classpath. In the script 
catalina.bat/catalina.sh the variable CLASSPATH is overwritten and all 
previous content is skipped. You can fix this by including the content 
of the CLASSPATH variable. There is also a script called 
setclasspath.sh/setclasspath.bat. You can change this also. I did not 
find a solution if you're using the Tomcat service under Win NT/2000/XP. 
If you need JARS outside the Tomcat installation you have to go this way 
and to start Tomcat using the scripts instead of using the service.

Change the line

set CLASSPATH=...

to (according to your plattform)

set CLASSPATH=%CLASSPATH%;... or
set CLASSPATH=${CLASSPATH};...

Greetings

Michael

All,

Does the UNIX Tomcat implementation ignore the CLASSPATH environment
variable ?

   


Yes.

 

For example, in order to make DBCP pooling work, I placed the Oracle JAR
file in $CATALINA_HOME/common/lib  Does this mean that all application JAR
files must be installed in ../common/lib ?

Thanks

Caching-Problem Tomcat 4.0.x (Tomcat 3.3.1 works)

[Michael Timpe]

Hi,

I have the following problem:

I have a servlet that creates as a result a (plain) html file on the server and saves 
it on the server. The browser than requests the html page to display it.

The html page created by the servlet is updated very fast (each second). To indicate 
this, the html page contains a time stamp to track the correct update of the page.

It seems that Tomcat4.0.x does not recognize that the html file has been changed and 
delivers the old version of the html page. Only if the browser is waiting about 5s 
until it requests the new created html page, it works.

With Tomcat 3.3.1 the servlet can update the html file as often as needed. Tomcat 
3.3.1 always delivers the newest version.

(In the html file there are the needed meta tags to avoid caching the page on the 
client side and to avoid caching in a proxy!)

So, my question is:

1) Does Tomcat 4.0.x have a problem that a static html page to be delivered has been 
updated within the last second?

2) Does Tomcat 4.0.x have any internal caching mechanisms (to avoid loading the html 
file from the disk for each request)? 

3) If so: Is there any possibility to configure this caching?

Greetings

Michael

Re: mod_jk with Apache 2.0.36/TC 4.0.4-b3 on NT

[Michael Timpe]

Hi,

I have a problem in the same area:

1) I put mod_jk2.dll to the modules dir of apache.

2) I added LoadModule jk2_module modules/mod_jk2.dll to my httpd.conf file

3) I added the directive JkMount /*.jsp ajp13 to my httpd.conf file

Testing the conf file using apache.exe -t httpd.conf, the following report
will be written:

"Invalid command 'JkMount', perhaps mis-spelled or defined by a module not
included in the server configuration"

I did not found any installation instructions for mod_jk2. The old
documentation for mod_jk seems not to be valid (JkMount definitely worked
with mod_jk).

Any ideas?

Greetings

Michael

Re: mod_jk with Apache 2.0.36/TC 4.0.4-b3 on NT

[Michael Timpe]

I gave up. I am using Apache 1.3.x with mod_jk and TC4.0.3 and it works
really fine. I will wait a little bit until the new versions are more
stable.

Greetings

Michael

Problems Apache 1.3 <-> Tomcat 4.0 and Security Constraints

[Michael Timpe]

Hi,

I have the following problem:

I wrote a web application using a security constraint with auth-method set to 'FORM'. 
Everything works fine.

I now will use Tomcat as the JSP container under Apache. If I access the application 
through Apache, the FORM-based
auth-method of tomcat seems not to work. ("not found error").

Does Apache supports Form-based login in a manner like Tomcat does?

Any ideas?

Greetings

Michael

Mime Mapping Problem

[Michael Timpe]

Hi,

I am working with Tomcat 4.x on a windows machine. In the wepapp-defaults a mime type 
mapping für jnlp file ist set correctly. But tomcat alwasy sends text/html as content 
type not application/x-java-jnlp-file. I tried always defining the mime type in the 
web xml file. But it didn't work.

What went wrong?

Caching of JSPs within Tomcat

[Michael Timpe]

Hi,

I have some trouble with the reload of JSPs.

Basic data is

- Win XP, Apache 1.3.xx, Tomcat 4.01, IE 6.0 (IE6 with the option to reload the page 
at each access)

Suppose You have an JSP page "prj_.jsp" that includes another JSP page by using a 
tag like this: <%@ include file="prj_0007.inc" %>

If I have changed the file prj_0007.inc and I press "Reload" in the browser. The 
changes will have no effect (are not loaded into the browser). I have to change
also the file "prj_.jsp" (by adding a blank line to the file to change the files 
modification date). 

How can I disable the "caching" of the JSPs within tomcat so that changes in included 
files have their effect?

Greetings and thank you for your help
