Hi,

Could the developers of mod_jk please add timestamp logging and if possible
request url to mod_jk.log ?

Thanks

Re : extracting jsp file name

[Shahed Ali]

Sorry for the confusion.

I have a MVC framework in which  all jsp pages post
data to a controller servlet.

In this servlet, I need to findout which jsp page invoked it.

Currently I am passing a hidden variable with value="/callingpage.jsp"

i.e in  calling.jsp I have the code fragment

form action="/servlet/controller"
input type="hidden name=referer" value ="calling.jsp"
/form

I want to replace this with some jsp token in each page so that i dont have
to
hardcode the jsp page name in every page.

At first I thought of using the HTTP referer header in the servlet, but that
only works
for the first time. The servlet does a servlet forward(), and so the next
time I look at
the HTTP Referer header, I get the name of the servlet and not the jsp page
which called the servlet.

The only way I could think of is getting the generated class name in jsp and
UnMangling it.

I could either do that or write my own Mangler class.

Now I looked at the Mangler code in CommandLineCompiler.java from jasper.
The interface file Mangler.java has a comment that says that I can *plug in*
my own mangler.

However, would that mean rewriting CommandLineCompiler since it implements
Mangler ?

Thanks
Shahed

REPOST : extracting jsp filename from generated class

[Shahed Ali]

Hi all,

Sorry for this repost.

From within a jsp page, I need to know the name of the jsp page.

If I do a %=this.getClass()%, I get a string which represents the class
name
of the generated servlet.

Is there some standard way in which I can extract the jsp page from that
name ?

Another Qs :- How does Tomcat know that a certain jsp page maps to
a certain class ?.
If I can access that data, then I can possibly lookup the pagename.

Any clues ?

Thanks
Shahed.

BIZZAR Caching Problem !!

[Shahed Ali]

Hi,

I am using Tomcat 3.2.1 w/Sun JDK 1.3 on Solaris 8 + Apache 1.3.14 + mod_jk

Now here is my problem.

I have a jsp page with an include to refer to file a.inc.
I change the include to refer to another file (b.inc)

I reload the page. I still see the content of a.inc.

I touch the jsp file. No change.
I go to the work directory and rm * (delete all generated class and java
files)
I reload the page. No change.

I look at the generated .java code for my jsp page. It sill includes the old
a.inc file.

FINALLY I restart tomcat.

Everything back to normal.

Can anyone tell me what was going on ? Does mod_jk somehow cache the jsp
file ?

Thanks
Shahed.

JSP generated .java Naming Convention

[Shahed Ali]

Hi,

I need to get the name of the current jsp page in a scriptlet.

The jsp page could be serverd up by a link or by a jsp:forward or a
redirect.

If I do

%=this.getClass()%, I get the following for a jsp page tmp/ST003.jsp

tmp._0002ftmp_0002fST_00030_00030_00033_0002ejspST003_jsp_1

Is there some standard way of extracting the jsp page name form this ?
Or is this naming convention subject to change ?

Or is there any other way ?

Thanks
Shahed.

Object Passivation in TC 3.2.x ?

[Shahed Ali]

Hi,

I am creating a connection pool in my jsp pages. 

This connection pool is a context wide static class that is 
referenced by 
each jsp page through a static class method.

If the website is inactive for about 2-3 hours, I get an error 
trying to get connections from the pool.

I suspect that this is due to that class being serialized. 


This does not seem to happen in tomcat 3.1 though. The same 
site / connection pool class works fine !!!

Is this my problem ? Is there any way to turn this 
off.

Thanks
Shahed.

Nightly Build Link broken ?

[Shahed Ali]

Hi,

I am trying to download Tomcat 3.2.1 B.

Is it the same as the release version of Tomcat 3.2.1 ?

In any case, the Nightly Build Link for downloading the source code 
of Tomcat seems to be broken.

Thanks
Shahed.

Reading SSL Client Cert in TC 3.2

[Shahed Ali]

Hi,

I am using Tomcat 3.2 with Apache Stronghold 
3.0.

I am aware that there are directives in TC 3.2 which allow SSL 
info to be passed back to Tomcat.

What I would like to know is whether there are any sample jsp 
/ servlet code or any website that 
shows me how I can retrieve SSL Client Certificate info and 
use it for authenticating the client.

I know that there is some class in the javax.security package 
that deals with X.509 certificates etc etc,
but what I am looking out for is sample code as I am very new 
to SSL and Client certificates (and good authentication methods) 
in general.

Thanks 
Shahed.

Client Certificate Auth

[Shahed Ali]

(Sorry if this is a bit off topic)

I am using Tomcat 3.1 with Apache - Stronghold.

I am new to SSL / Digital certificates, and was wondering if any one can
point me to
any example code / url or even a book title which has an example of how to
read a client digital certificate and grant access to users based on that.

Firstly is this supported in Tomcat 3.1 with Apache as the web server ?

Also is there any way that I can dispense certificates off my web server
rather than
ask the users to get a certificate from a CA.

Thanks
Shahed.

Cannot compile mod_jk under Solaris 8 Intel

[Shahed Ali]

Hi,

I am having a problem compiling mod_jk on 
Solaris 8 (Intel) for Tomcat 3.2.

I have tried with both jdk1.2.1 and jdk1.2.2 for 
the include files since I know that Tomcat 3.1 had a problem with 
1.2.2

Anyway, if I dont give the -lposix4 flag, I get 
the fdatasync symbol not found error.

If I do give the -lposix4 flag, I get a message 
saying that cannot start server.

BTW, I am using StrongHold (Apache 1.3.14) and 
the apxs etc are from stronghold.

Thanks
Shahed

Tomcat 3.2 on Solaris 8 with Sun JDK 1.1.2

[Shahed Ali]

I have faced this problem earlier with Tomcat 
3.1.

It just does not seem to work with JDK 1.2.2.

When I access a jsp, the .java file under the work 
directory get stuck at 


out.write(html\r\n!--\r\n Copyright 
(c) 1999 The Apache Software Foundation. All rights \r\n 
reserved.\r\n--\r\n\r\n);

It works fine if I set JAVA_HOME to jdk1.2.1

Is this bug fixed in later versions ?

Thanks
Shahed

Fw: Virtual Hosts and Context Path Question

[Shahed Ali]

[EMAIL PROTECTED]Cc:

[EMAIL PROTECTED]Date: 
Friday, December 01, 2000 11:33 AMSubject: Virtual Hosts and 
Context Path Question
I am running Apache Stronghold with Virtual 
Hosts and Tomcat 3.1

I am using Named Hosts and have www.a.com and www.b.com both pointing to the same IP 
address.


Now when I go to http://www.a.com I want my DoucmentRoot to point to 
/usr/local/jakarta-tomcat/webapps/A_APP/index.jsp
But I also have to modify the Context Path = 
 in server.xml to point to webapps/MYAPP

Now suppose I want http://www.b.com to point to 
/usr/local/jakarta-tomcat/webapps/B_APP/index.jsp, I would need
to also set the Context path =  
?

How can I go about doing this ?

 

 
OR


Or If I have virtual hosts using the same Tomcat 
Server, then do I need to keep all my jsp stuff in different contexts and 

Set up an alias in each virtual host = Context 
Path ?

So when I want to serve up jsp pages for site A I say http://www.a.com/siteAjsp/myapp.jsp

And when I want to serve up jsp pages for site B I say http://www.b.com/siteBjsp/myapp.jsp

Where siteAjsp , siteBjsp etc all have to be unique 
aliases/context-paths combinations.

Eg

NameVirtualHost 192.168.5.100

Virtual Host 192.168.5.100
ServerName www.a.com
DocumentRoot /home/a
Alias /siteAjsp 
/usr/local/jakarta/tomcat/webapps/siteAjsp
ApJServMount /siteAjsp/servlet /siteAjsp
Location /siteAjsp/WEB-INF
.
/Location
/Virtual 
Host 
 For this Host in server.xml 
Context path=/siteAjsp docbase = 
webapps/siteAjsp


Virtual Host 192.168.5.100
ServerName www.b.com
DocumentRoot /home/a
Alias /siteBjsp 
/usr/local/jakarta/tomcat/webapps/siteBjsp
ApJServMount /siteBjsp/servlet /siteBjsp
Location /siteAjsp/WEB-INF
.
/Location
/Virtual 
Host 
 For this Host in server.xml 
Context path=/siteBjsp docbase = 
webapps/siteBjsp

Thanks
