More JDBCRealm Questions
I have set up a JDBCRealm and am using it with form-based login to secure/protect my webapp. However, I have a few questions which I hope somebody could help me with, 1. The JDBCRealm is set up with the following in server.xml. Realm className=org.apache.catalina.realm.JDBCRealm debug=99 driverName=org.gjt.mm.mysql.Driver connectionURL=jdbc:mysql://localhost/authentication userTable=users userNameCol=user_name userCredCol=user_pass userRoleTable=user_roles roleNameCol=role_name/ However, I have noticed that this requires the password (stored in the user_pass column) to be clear text, which I really don't like doing. Is there any way to have store the passwords as hashes (ie. using the password() function in MySQL) ? 2. I read that a call to j_security_check will be made by every attempt access your secured pages. Since I am protecting every page in my webapp, I'm wondering how efficient is j_security_check ? Does it simply look at the session, or does it make a database call on each and every request ? 3. How do you specify a page for authenticated users who do not have the correct permissions/roles ? At the moment, I have this in web.xml, login-config auth-methodFORM/auth-method form-login-config form-login-pagelogin.jsp/form-login-page form-error-pagelogin-error.jsp/form-error-page /form-login-config /login-config login.jsp is the form that shows when an authenticated user tries to access the site. login-error.jsp is displayed when an incorrect username/password is submitted. However, when a correct username/password is submitted but the user does not possess an adequate role, I see a default You are not authorized message. How can I customize the page that is shown in such circumstances ? 4. Is there a formal method to logging out, rather than calling invalidate() on the session ? 5. If your webapp's authentication works fine on Tomcat, would it then work on say BEAWeblogic or IBMWebsphere ? Sorry for so many questions but I can't find a comprehensive description of this anywhere. I've only found setup/configuration guides which deal with the simple issues.

Re: More flexible JDBCRealm implementation ? (for ASP-style webapp)
From: [EMAIL PROTECTED] (Will Hartung) I've setup a JDBCRealm for Tomcat using MySQL. It works OK but the database schema is not good for an ASP (application service provider) model. For example, I would like several companies to use the same webapp (each company should not know of the other's existence) and each should be able to create a user 'admin' and a user 'david' but in the way that JDBCRealm is currently configured only one instance of any user name is possible since it is the primary key in the users table. Is there a better way to do this ? I'm not familiar enough with MySQL, but I'll toss this out. Since you can configure your Realms on a Webapp basis, that may give you the flexibility you need. For example, if you were using, say, Oracle, or most any other database that has a concept of User ownership for its tables (most DBs do, MySQL may do this, I don't know), you could set up seperate Users or Schemas in the database for each Client Webapp. This way, each client would have access to their own versions of the tables. You would distinguish the realms by each having their own login to the client database with a client specific username/password for the database. Yes, but this adds complexity due to different table names for different clients. I like to keep things simple. So, I can do what you suggest except with different databases (running on the same MySQL instance) for different customers and webapps. That's my current setup. If you'd rather share the tables (for whatever reason), perhaps you could make views on a master table that's limited by the client id. I do prefer to share the tables. The reason is that you can easily set up new clients and customers without restarting Tomcat. Better yet, users can register and sign-up themselves, something that's not possible if I have to set up a different database for them, with its own JNDI resource configuration in server.xml These views would be placed in the appropriate client schemas and shadow the master table in a central schema. Something like CREATE VIEW CLIENT1.USERS(user_name, user_pass, user_goupid) AS SELECT user_name, user_pass, user-groupid FROM MASTER.USERS WHERE CLIENTID = 'CLIENT1'. I'll have to investigate this use of views. It's something I'd never considered before and looks very useful. Finally, if you look at $CATALINA_HOME/src/share/org/apache/cataline/realm/JDBCRealm.java, it looks pretty darn simple to tweak that to do whatever you want, or, better, to subclass and change the relevant methods (not many from the looks of it). The only fear here is that the TC team can change JDBCRealm behind your back in a later release. I'd much rather avoid something this drastic. It would be better for me to write a filter and use custom authentication I believe. Stick the pertinent webapp specific entries into ENV-ENTRY, and you can do all sorts of scary things I would think.

[EMAIL PROTECTED] === If you use MVC (I use Struts) you tend to do everything in beans and actions. So you can have a bean that goes against a db(and can get other user info) and keep in session the organization_id. Then on updates and retrieves append in action the organization_id.

Yes, I've done something like that too. But have therefore found that the Tomcat out-the-box JDBCRealm setup (using server.xml, web.xml as I described below) is not flexible in any way. So it looks like I too will have to use a manual authentication which I had hoped to avoid in the name of standardization. Oh well. I know how to manualy code (using getuserpricipal and a bean) but nothing automatic I can think of. Why use getUserPrincipal ? I thought we were supposed to use request.getRemoteUser() ? Also, may I ask by what you mean a bean for this ? I really like to design code (including Javabeans) so that they will run in standalone applications, as well as in the servlet container environment. Is it possible to design an authentication mechanism that is not dependent upon the servlet container (eg. Tomcat) ? Soefara. Vic Soefara Redzuan wrote: I've setup a JDBCRealm for Tomcat using MySQL.

Betreff: some questions about tomcat ..urgent!
1) Can there be 2 instances of TomCat webserver on the same machine?
Yes
b) Can the same webserver executable be run as separate process
instances?
Yes
c) Do the separate process instances of the webserver share the
same webserver configuration or different webserver
configuration file?
Each process instance has it's own configuration.
We have a structure like this:
/www/online/site
/conf
web.xml
server.xml
Files that contain the site specific setup for tomcat
...
/bin
start.sh
Script that calls the tomcat that we want to use for
this site with the environment for this site:
JAVA_HOME=/usr/local/java/jdk/sun1.3.1
CATALINA_HOME=/usr/local/java/tomcat-4.0.3
CATALINA_BASE=/www/online/site
export JAVA_HOME CATALINA_HOME CATALINA_BASE

/usr/local/java/jdk/sun1.3.1
/usr/local/java/jdk/sun1.4
/usr/local/java/tomcat-4.0.3
/usr/local/java/tomcat-4.0.4
This way we can have different versions of tomcat at the same time,
all sites that use the same tomcat version use the same 'executable'
and individual configuration. If we want to use an other version of
tomcat we just have to change CATALINA_HOME in start.sh (unless the
config files are incompatible between these versions)
d) Memory footprint of the executable?
That depends on several factors. In my environment a freshly started
tomcat has 217404KB (virtual size) and 28032 (resident size)

Hi Ralph
thanks for a quick reply, i understood the way its being run at ur end..but i didn't
mean running different versions at the same time
i'll try to elaborate the doubts
1. when i said 2 instances , i meant 2 instances at the same time e.g. for load
balancing
can u run them concurrently with only single tomcat installation.
2. will i need to do any changes in the configuration for the second process to run
e.g. port no etc
coz i'll have only single installation of tomcat

RE: How to compile Tomcat 4.0.3 with JBuilder?
Hi,
Compiling tomcat from scratch is explained in the manuals.
You can create a tomcat launcher to run TOMCAT in Jbuilder ,this will allow you to
debug servlets (include the sources you want to debug in your JBuilder project). It
even works with JBuilder personal.
Add the tomcat classes in a library and in your project. The activation.jar contains
the Tomcat Main() method in the class below. You also have to change the catalina.base
path to your tomcat directory.)
Here is the source for the launcher:
**
import org.apache.catalina.startup.Catalina;
public class launcher {
public static void main(String[] args) {
System.setProperty(org.xml.sax.parser,
org.apache.xerces.parsers.SAXParser);
System.setProperty(javax.xml.parsers.DocumentBuilderFactory,
org.apache.xerces.jaxp.DocumentBuilderFactoryImpl);
System.setProperty(catalina.base, c:\\jwsdp-1_0-ea2 );
String argC[] = { start };
Catalina.main( argC );
}
}
Now, compile the Launcher application only. Set breakpoints in the sources you want to
debug.
Bonus: Check the Catalina source to see which other options are accepted by the main
method.
If you decide to build a swing applican which allows you to start, stop and pause
tomcat, send me a copy ;-)
Cheers / Christophe

Integrating Apache 2.0.36 and Tomcat 4.0.4 on Win32
Hi all,
My name is Aleksandr Jones. Greetings to all Apache of the open source
community.
I am attempting to get Apache 2.0.36 and Tomcat 4.0.4 connected, so that
static
content is served by the former and dynamic by the latter. I am running
Windows
2000 SP2 on an Intel Machine. I mainly used the galatea.com flash guide for
integrating Apache 2.0.36 and Tomcat 4.04 as a guideline for this.
I have done the following steps:
I downloaded the JDK 1.4 installation file --
j2sdk-1_4_0_01-windows-i586.exe
My JDK 1.4 is installed in C:\j2sdk14
My environment variables are set as follows:
%JAVA_HOME% = C:\j2sdk14\
%PATH% = %PATH% -- append C:\j2sdk14\; C:\j2sdk14\bin
That's my Java stuff.
I downloaded and ran the windows installer (MSI) installation for Tomcat
4.0. I
ran the installation and put tomcat in C:\Tomcat4\
My environment variables are thusly set:
%Catalina_Home% = C:\Tomcat4\
%Tomcat_Home% = C:\Tomcat4\
Tomcat is installed as a service, so I start the sucker up and check it out:
http://localhost:8080/ -- and I immediately see the Tomcat page:
If you're seeing this page via a web browser,
it means you've setup Tomcat successfully. Congratulations!
There's my Tomcat stuff for now.
I downloaded the source code for Apache HTTP Server 2.0.36.
My environment variables are thusly set:
%Apache2_Home% = C:\Apache2\
%Apache_Home% = C:\Apache\
I built the INSTALLBIN configuration in my *ahem* Microsoft Visual Studio,
and it produced my Apache2 configuration.
I run Apache from the command line, and test http://localhost:80
For which it responds:
If you can see this, it means that the installation of the Apache web
server
software on this system was successful etc.
Next, I downloaded Apache Ant 1.5, and extract it to C:\JakartaAnt\bin;
My environment variables are thusly set:
%PATH% = %PATH% -- append C:\JakartaAnt\bin;
There goes Ant.
Next I downloaded jakarta-tomcat-connectors-4.0.2.01-src.zip. I extracted
to the directory C:\JKConnectors\
Here is a dump of the file C:\JKConnectors\jk\build.properties

Now, after repeatedly failing to use the
mod_jk.dll from http://www.acg-gmbh.de/mod_jk/, I went and compiled
the one in the C:\JKConnectors\JK\Native\Apache-2.0.
(Notice, these failures were marked by error messages and Apache
failing start; I excluded this data since I got past it with my
homegrown version)
So, *poof*, now I have mod_jk.dll. I copy mod_jk.dll into
C:\Apache2\Modules\ directory.
Now, I went to my Tomcat server.xml file and modified it thusly:
1.) The log file listener:
Server port=8005 shutdown=SHUTDOWN debug=0
Listener className=org.apache.ajp.tomcat4.config.ApacheConfig
modJk=c:/Apache2/modules/mod_jk.dll jkDebug=info
workersConfig=c:/Tomcat4/conf/jk/workers.properties
jkLog=c:/Tomcat4/logs/mod_jk.log/
2.) Get the AJP Connector listening on port 8009
Service name=Tomcat-Standalone
!-- Define an AJP 1.3 Connector on port 8009 --
Connector className=org.apache.ajp.tomcat4.Ajp13Connector

RE: context-param for a list/array of values ?
Howdy,
There are a couple of ways. My favorite is:
param-namejndi.resources/param-name
param-valuejndi/a,jndi/b,jndi/c/param-value
String jndiString =
getServletContext().getInitParameter(jndi.resources);
StringTokenizer st = new StringTokenizer(jndiString, ,);
ArrayList jndiResources = new ArrayList();
while(st.hasMoreTokens())
{
jndiResources.add(st.nextToken());
}
That's it, very simple. ;)

Subject: context-param for a list/array of values ?
In web.xml, variables can be defined like this,
context-param
param-namegui.bgcolor/param-name
param-value#00/param-value
/context-param
And then in your servlet or JSP,
String guiBgColor =
getServletContext().getInitParameter(gui.bgcolor);
But how can I assign a list or array of values to a variable
in web.xml ? For example, I wish to configure the available
JNDI datasources available to a webapp, so that the end user
can select one. Is it something like this ?
context-param
param-namejndi.resources/param-name
param-valuejdbc/users/param-value
param-valuejdbc/accounts/param-value
param-valuejdbc/finance/param-value
/context-param
But then how would I extract values in my JSP or servlet ?

RE: Best practice for virtual host configuration
if your context is under the appBase, then it will autoload it. If your context is not under the appBase(shared contexts), then you have to provide the path to it. I've never tried leaving docBase empty for a context, so I don't know what path it would look under. I guess webapps could be assumed as the default directory for defined contexts even if you change the appbase. so you changed your example to: Context path= docBase= debug=1 reloadable=true /Context This would take the ROOT context, which is fine if all your virtual hosts use ROOT as their root context. I have different contexts that are the default context for their virtual hosts, so I have to provide a docBase to distinguish between them. My configuration is similar to your original except that I have a dummy appBase(prevent autoloading) and specify a absolute path for docBase.

This looks long but it's actually straightforward.
I can't get the JNDIRealm config to work Netscape Directory Server 3.1.
I suspect the conf. of the JNDIRealm elment is wrong but don't know why.
I have a LDIF file exported from Netscape Directory Server 3.1 which
define(loosely speaking)
- an admin user that I use in JNDIRealm for initial connection
- a sales person
- a SalesGroup role which has sales person as a member
Other stuff removed for clarity.

roleSearch=(uniquemember={0})
roleSubtree=true
userPassword=userpassword
userPattern=uid={0},o=company.com

I have tried many combinations of patterns and attributes in the
above configuration but none worked.
The initial connection and authentication using admin seemed to work OK.
But I can't get it to authenticate the sales person/salesGroup.
I enter the salesID as the username and its password in the auth.

Re: Integrating Apache 2.0.36 and Tomcat 4.0.4 on Win32
I basically did the install like you did below and everything works
fine for me when I just use 'localhost' and try the stuff on the
particular machine where everything resides. However no matter what I
try I can not get apache2.0.39 to pick up any Tomcat applications when
typing in the url from another machine. I'm tyring to set up under a
different port 7000... and
http://afs.outback.com:7000/ brings up apache fine
http://afs.outback.com:8080/myApp/ brings up tomcat fine
http://afs.outback.com:7000/myApp/ no good doesn't serve up my tomcat
app
However running on the machine where the server is and use localhost
above and everything is fine.
Very frustrating that I can't find documentation on this.
If anyone has ideas let me know.
Aleksandr, double check your set up with this doc
http://mpcon.org/temp/how2install_apache_w_php_jsp_support.doc
It worked fine for mine under localhost but still having problems
above.

Re: localhost vs IP address in the URL
I'm not a networking guru, (and this is sort of OT for Tomcat) but I'm not convinced by M.Schwartz's response that this is due solely to DNS name resolution. I don't think that would account for such a big difference in time--once the name was resolved to the IP address, behavior should be the same, no? Saravanan, you say there's a 20x difference but what's the magnitude? Are we talking 10 ms vs. 200 ms. or 1 second vs 20 seconds? By IP address do you mean 127.0.0.1 or the IP address of the computer? My pet theory is that the TCP/IP stack is recognizing the IP address as being of the local box and is shortcutting packets from transmit queues to receive queues in memory, without actually getting the NIC involved or anything. Or maybe the NIC is doing this. Many years ago when I did hardware testing, we first ran into TCP/IP stacks that had this optimization. The other thought is that for some reason different maximum packet sizes are being used with these different connections? Of course, this is just a theory. Someone with a little more knowledge might be able to speak more authoritatively grin. dwh Saravanan Bellan wrote: Windows 2000 Tomcat 3.2.3 If I try to upload a file using the regular HTML/HTTP, there is a 20x difference in performance between using localhost vs the IP address in the Web Server URL.

[EMAIL PROTECTED] === I was just thinking of a design I did for ASP model: Create a dispatch web app with single sign on (over multiple apps) Say you have 4 clients, that is 4 virtual hosts, plus one dispatch host. When people login in, they go to distpach and login in via JDBC relms to the dispatch web, they login with their e-mail or something. Once autethicated, you create a bean that find out what web app they should go to based org_id. And then each action (retrieve or update) appends org_id to db tables. It worked. So JAAS up front, and a bean and action in the back. I could write up an implementation. one day. Vic Soefara Redzuan wrote: Thank you for the reply Vic. From: Vic C.

But have therefore found that the Tomcat out-the-box JDBCRealm setup (using server.xml, web.xml as I described below) is not flexible in any way. So it looks like I too will have to use a manual authentication which I had hoped to avoid in the name of standardization. Oh well. I know how to manualy code (using getuserpricipal and a bean) but nothing automatic I can think of. Why use getUserPrincipal ? I thought we were supposed to use request.getRemoteUser() ? Also, may I ask by what you mean a bean for this ? I really like to design code (including Javabeans) so that they will run in standalone applications, as well as in the servlet container environment. Is it possible to design an authentication mechanism that is not dependent upon the servlet container (eg. Tomcat) ? Soefara. Vic Soefara Redzuan wrote: I've setup a JDBCRealm for Tomcat using MySQL.

Is there a better way to do this ? I followed instructions found on many websites for setting up a JDBCRealm. The table schema is create table user_groups ( group_id int not null auto_increment, group_name char(24), parent_id int not null default -1, primary key(group_id) ); create table users ( user_name varchar(32) not null, user_pass varchar(32) not null, user_groupid int not null default -1, primary key(user_name) ); create table user_roles ( user_name varchar(15) not null, role_name varchar(15) not null, primary key (user_name, role_name) ); And in Tomcat's server.xml I have this in the appropriate context, Realm className=org.apache.catalina.realm.JDBCRealm debug=99 driverName=org.gjt.mm.mysql.Driver connectionURL=jdbc:mysql://servername/databasename userTable=users userNameCol=user_name userCredCol=user_pass userRoleTable=user_roles roleNameCol=role_name/ And finally this in the webapp's web.xml, security-constraint web-resource-collection web-resource-nameProtectedApp/web-resource-name url-pattern/*/url-pattern http-methodPOST/http-method http-methodGET/http-method /web-resource-collection auth-constraint descriptionname the security roles that are allowed to access/description role-nameadministrator/role-name role-nameuser/role-name /auth-constraint /security-constraint The alternative is to set up a separate webapp for each company that wishes to use our service but that really isn't scalable and doesn't allow for users to self-register and be up-and-running without administrator intervention.

Re[2]: Apache Authentication
Hello Kevin, That's a question for the developers. I don't think it is possible, actually. I think if you set your BASIC auth up in the web.xml and in Apache, then you get the case where, when you go through Apache on port 80, you get prompted for username/password by Apache and then again by Tomcat. However, in this setup, if you went to port 8080, directly to Tomcat, then it would work fine. So, you kind of need to make a choice as to whether to disable the authentication set in web.xml and just use Apache or just let Apache forward the request without asking for authentication and let Tomcat deal with that. It sure seems like a better solution ought to be possible.

Re: Re[2]: Apache Authentication
Just a thought, might not be true (since I haven't checked this behaviour). When you go through Apache (and if Apache has BASIC authentication setup), the Apache authentication will take precedence. Once you have entered the userid/password in the authentication dialog box, the browser will from then on keep sending the Authentication header (Base64 encoded userid/pwd) to the webserver. So if Tomcat has a BASIC authentication setup too, then it will not send a 401 response code since the browser has sent the Authentication header (ofcourse the userid/pwd for both Apache and Tomcat should be the same. Else Tomcat will send a 401 response code).

It seems, if a servlet returns content (dynamically built HTML for instance) which exceeds 8192 in length, the content is truncated at 8192 and a blank page is rendered by Apache. Actually, Apache renders what was returned by Tomcat (8192 bytes of the dynamically generated HTML page).

The JDBCRealm is set up with the following in server.xml. Realm className=org.apache.catalina.realm.JDBCRealm debug=99 driverName=org.gjt.mm.mysql.Driver connectionURL=jdbc:mysql://localhost/authentication userTable=users userNameCol=user_name userCredCol=user_pass userRoleTable=user_roles roleNameCol=role_name/ However, I have noticed that this requires the password (stored in the user_pass column) to be clear text, which I really don't like doing. Is there any way to have store the passwords as hashes (ie. using the password() function in MySQL) ? The database password isn't the only sensitive piece of information in server.xml -- you should ensure that the server.xml file as a whole is not accessible to any OS user other than the one running Tomcat. In addition, you can use security manager protections to prevent webapps from being able to access it directly. 2. I read that a call to j_security_check will be made by every attempt access your secured pages. Since I am protecting every page in my webapp, I'm wondering how efficient is j_security_check ? Does it simply look at the session, or does it make a database call on each and every request ? If you are using sessions, the user identity is cached the first time, so the database will only get hit once. 3. How do you specify a page for authenticated users who do not have the correct permissions/roles ? At the moment, I have this in web.xml, login-config auth-methodFORM/auth-method form-login-config form-login-pagelogin.jsp/form-login-page form-error-pagelogin-error.jsp/form-error-page /form-login-config /login-config login.jsp is the form that shows when an authenticated user tries to access the site. login-error.jsp is displayed when an incorrect username/password is submitted. However, when a correct username/password is submitted but the user does not possess an adequate role, I see a default You are not authorized message. How can I customize the page that is shown in such circumstances ? You can use an error-page element in your web.xml for the 403 status. 4. Is there a formal method to logging out, rather than calling invalidate() on the session ? Not in Servlet 2.3. Such things are under consideration for 2.4. For now, invalidating the session is the right way to do it (if you're using form based login). 5. If your webapp's authentication works fine on Tomcat, would it then work on say BEAWeblogic or IBMWebsphere ? As long as you are not relying on wierd container-specific behaviors and using j_security_check the way it was intended to be used. Note that the user database itself, and how you set it up, will be specific for each app server (i.e. JDBCRealm is Tomcat specific). But the app won't have to change. Sorry for so many questions but I can't find a comprehensive description of this anywhere. I've only found setup/configuration guides which deal with the simple issues. Soefara.

With a 'real' database each web application can use the same table name. You just must configure the web application to use a different schema (catalog, database, ; the terms differ from vendor to vendor) I do prefer to share the tables. The reason is that you can easily set up new clients and customers without restarting Tomcat. Better yet, users can register and sign-up themselves, something that's not possible if I have to set up a different database for them, with its own JNDI resource configuration in server.xml snip/ I'll have to investigate this use of views. It's something I'd never considered before and looks very useful. With mysql you better forget it. Currently there are no views in mysql. (Altough chances have improve that there will be views in a future version.

Anyone have any hard and fast rules, good links, general info, do and don't lists, or anything about these two? We moved from iPlanet 4.1 where we did all redirection with response.sendRedirect. That didn't work with tomcat so I started using the forward method of RequestDispatcher. Well, now I need to use a NON relative path to redirect the user off our site. While I think response.sendRedirect will work in this instance I cannot seem to formulate a theory why it works here and not in other parts of our site. Does anyone have any information on this I can read, or advice? Thanks! Jason -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Poolman with Tomcat
Hi I have Tomcat 4.0.4 / Apache 1.3 working with mod_jk. I am trying to integrate poolman 2.0 into the system. Here is what I think I should do, 1. Place poolman.xml in WEB-INF/classes directory of the application 2. Place poolman.jar in WEB-INF/lib directory , I believe Tomcat 4x comes with most of the other required libs. 3. Setup JNDI based Datasource 4. Write code to invoke JNDI Datasource i.e pool for each db request. The question is - does poolman make use of JNDI inside Tomcat automatically or do I have to configure one manually with Tomcat? Any best practises ? Unfortunately, tomcat pooling did not work for me . Any reason why Tomcat does not come with DB Pooling by default ? Why would anyone not use pooling ? Beats me.

Re[4]: Apache Authentication
Hello rsequeira, Good point. However, that means you have to keep your user authentication info in two different places...unless you are pulling the info a single source such as JNDI or JDBC for both Apache and Tomcat. Also, in that case, the structure of the JNDI and JDBC entries for both Apache and Tomcat have to be pretty close to identical. Notice the issues brought up by users unhappy with how SingleSignOn work with Tomcat and how the structure of the database forced by Tomcat's implementation doesn't quite meet their needs.

I don't want to get involved in a programming practice debate BUT.. Too late ... :-) The performance hit from exceptions occur because exceptions are thrown, not in how they are handled. You cannot programatically avoid exceptions with xhaustive checking that would itself hinder performance. Specifically potential SQL errors are punexceptionally/pun difficult to cater for. (dropped connections, network problems, constraint violations) .Exceptions are only thrown when something goes wrong. The point I was trying to make was that exceptions are not only a sign of system failure, but one of usage failure too. Because SQLException is a checked exception, you can't throw it directly from a servlet anyway, so your database accesses are already encapsulated in try/catch blocks. You've already paid all the cost of checking already -- you actually have to deliberately rethrow it (wrapped in a ServletException) to allow your filter to see it. Why go to all that extra work? Anyway, what I was trying to do was to implement a transaction logging filter that determined if a particular database write operation had worked. The code is simple and checks if a servlet/jsp has thrown an exception to check for success/failure. If the servlet/jsp completes without throwing an exception, I commit the transaction, otherwise I roll it back. This is not the way you should program database applications! It is very very dangerous to depend on external logic to commit or roll back transactions for you. If an exception happens, it should be logged and dealt with when it happens. Database access logic should always catch its own exceptions, and commit or roll back the transaction appropriately. In a web app, it is considered irresponsible programming for a servlet to leave an open database transaction after it returns from the service() method, for whatever reason that might happen. To say nothing of returning the connection to the connection pool you got it from. Is there some recognised way to pass servet/jsp error conditions to filters? This would prevent me relying on exceptions (altho' exceptions would have to be catered for too). I suppose I could use the request.getAttribte()? Are exceptions that are trapped in a filter 'seen' and handled by Tomcat? Your problem is that Tomcat sees the exception thrown by the servlet before it is passed back to the filter. That's where the logging is happening. And that's not going to change (in the standard Tomcat release -- you're perfectly free to modify your own copy), because handling exceptions is not what filters are for. TIA - Mark Craig I'll second what Craig has said and add that if your program normally throws lots of exceptions, then you should look at some of your design decisions. Exceptions are wonderful when used for Exceptional behavior, but not for normal runs. They are also REALLY slow. Exceptions can kill your performance, and if you are getting them regularly, you should catch the ones you can safely ignore as early as possible and toss them away as appropriate, or even better, not throw them at all.

Re: Apache 2.0.39 and Tomcat 4.1.8 Servlet issue
Hi, Dave. Did you check your log files for exceptions? I've seen behavior similar to what you're describing with Tomcat 4.0.x running Standalone. What I've seen is that it gets a full buffer's (defaults to 8K, like you're seeing, but can be set to different size) worth of content and displays it. Then, it runs into a NullPointerException (or probably some other exception, but, usually for me, it's a good ole NPE) while trying to generate the next buffer's worth of content. At this point, the browser doesn't show an error page but just stops with only the one buffer's worth of content displayed. Maybe Apache renders the page as blank, but I usually get the partially returned page, as far as it can be rendered. Besides the partial page, the only sign that something went wrong is in the log. I've been meaning to look into this to see if it's a reported bug, but haven't yet. Is this what you're running into? -Jeff Short, Dave dave.short@pTo: 'Tomcat Users List' [EMAIL PROTECTED] fizer.com cc: Subject: Apache 2.0.39 and Tomcat 4.1.8 Servlet issue 07/24/02 10:59 AM Please respond to Tomcat Users List There is an issue with Apache 2.0.39 and Tomcat 4.1.8 (actually this issue first appeared with Apache 2.0.36 and Tomcat 4.0.x).

RE: Survey question for any Tomcat or Apache users out there
Just for grins, have you tried it with Apache on port 80? I realize you probably have good reason to run it on port 7000, it just helps if you can say I did it the default way and it worked, but this other way it didn't. I took a quick look at the doc at the link you posted. One thing I can say from experience: if you have any pathnames anywhere in your apache+mod_jk+tomcat config, get rid of them. Don't use Program Files/Apache Group etc. Use Apache/Apache and C:\tomcat, etc. While the apache installer probably lets you specify paths with spaces, and probably even recommends them by default, and probably works with them, the Apache HTTP developers don't co-ordinate with anyone else. Likewise, the various connector and tomcat projects are not co-ordinated. There's no guarantee that just because the apache installer lets you use spaces that every other Jakarta project will be happy with them.

Re: Re[4]: Apache Authentication
Yeah, it'd would be a good idea to store the authentication information - userid/pwd - in one place. And then use LDAP or JNDI. If you store the info in the database, only Tomcat would be able to access it (unless you use LDAP - maybe Apache has a LDAP module). Also I'd suggest either Tomcat or Apache handle the authetication, not both.

Apache 2.0.39, Tomcat 4.1.8 (mod_jk2) on W2K
The following steps, and attached files, were first posted by Mladen Turk. I modified those steps slightly. Actually, they didn't work completely until I tried it with Tomcat 4.1.8. I'm using JDK 1.3.1. 0. Install Java 1.3 1. Download jakarta-tomcat-4.1.8.exe from http://jakarta.apache.org/builds/jakarta-tomcat-4.0/test/v4.1.8/bin/ and install into c:\tomcat. 2. Set the TOMCAT_HOME (c:\tomcat) as system environment variable and reboot. 3. Install Apache 2.0.39 into c:\apache2. 4. Download mod_jk2.dll from http://jakarta.apache.org/builds/jakarta-tomcat-connectors/jk2/nightly/win32 / 5. Copy mod_jk2.dll to c:\apache2\modules. 6. Add the following line to the c:\apache2\conf\httpd.conf file: LoadModule jk2_module modules/mod_jk2.dll 7. Copy the attached workers2.proterties to c:\apache2\conf (change the paths accordingly). 8. Copy the attached jk2.properties and to c:\tomcat\conf (change the paths accordingly). 9. Run Apache (It will start the tomcat inprocess) 10.

Did you check your log files for exceptions? I've seen behavior similar to what you're describing with Tomcat 4.0.x running Standalone.

At this point, the browser doesn't show an error page but just stops with only the one buffer's worth of content displayed.

Subject: Re: More flexible JDBCRealm implementation ? (for ASP-style webapp)
Yes, but this adds complexity due to different table names for different
clients. I like to keep things simple. So, I can do what you suggest
except
with different databases (running on the same MySQL instance) for
different customers and webapps. That's my current setup.
Yeah, that's basically what I was talking about.
If you'd rather share the tables (for whatever reason), perhaps you could
make views on a master table that's limited by the client id.
I do prefer to share the tables. The reason is that you can easily set
up new clients and customers without restarting Tomcat. Better yet, users
can register and sign-up themselves, something that's not possible if I
have to set up a different database for them, with its own JNDI resource
configuration in server.xml
These views would be placed in the appropriate client schemas and shadow
the
master table in a central schema. Something like CREATE VIEW
CLIENT1.USERS(user_name, user_pass, user_goupid) AS SELECT user_name,
user_pass, user-groupid FROM MASTER.USERS WHERE CLIENTID = 'CLIENT1'.
I'll have to investigate this use of views. It's something I'd never
considered before and looks very useful.
Many DBMS (again, I don't know about MySQL) will allow you to not only read
using these kinds of views, but also update the data through the view.
Finally, if you look at
$CATALINA_HOME/src/share/org/apache/cataline/realm/JDBCRealm.java, it
looks
pretty darn simple to tweak that to do whatever you want, or, better, to
subclass and change the relevant methods (not many from the looks of it).
The only fear here is that the TC team can change JDBCRealm behind your
back
in a later release.
I'd much rather avoid something this drastic. It would be better for me
to write a filter and use custom authentication I believe.
Stick the pertinent webapp specific entries into ENV-ENTRY, and you can
do
all sorts of scary things I would think.
I'd really reconsider. If you look at the code for a JDBCRealm, it's APPEARS
really trivial.
Here you go. Inspired by the JDBCRealm class, it allows you to specify the
actual SQL you wish to use in the Database. Credential will return the
password, and roles will return the roles for the user. The single argument
for both SQLs will be the username.

Re: Is there any way to stop exceptions getting logged to log file?
You're right. It is too late! I don't want to get involved in a programming practice debate BUT.. Too late ... :-) The performance hit from exceptions occur because exceptions are thrown, not in how they are handled. You cannot programatically avoid exceptions with xhaustive checking that would itself hinder performance. Specifically potential SQL errors are punexceptionally/pun difficult to cater for. (dropped connections, network problems, constraint violations) .Exceptions are only thrown when something goes wrong. The point I was trying to make was that exceptions are not only a sign of system failure, but one of usage failure too. Because SQLException is a checked exception, you can't throw it directly from a servlet anyway, so your database accesses are already encapsulated in try/catch blocks. You've already paid all the cost of checking already -- you actually have to deliberately rethrow it (wrapped in a ServletException) to allow your filter to see it. Why go to all that extra work? Anyway, what I was trying to do was to implement a transaction logging filter that determined if a particular database write operation had worked. The code is simple and checks if a servlet/jsp has thrown an exception to check for success/failure. If the servlet/jsp completes without throwing an exception, I commit the transaction, otherwise I roll it back. This is not the way you should program database applications! It is very very dangerous to depend on external logic to commit or roll back transactions for you. If an exception happens, it should be logged and dealt with when it happens. Disagree. That is just micro managing exceptions. Transactions are the example of where a wrapper try/catch block around a series of SQL statements is a much better way to do it than try/catching each one. Also subsequent non database actions can cause a rollback. Database access logic should always catch its own exceptions, and commit or roll back the transaction appropriately. In a web app, it is considered irresponsible programming for a servlet to leave an open database transaction after it returns from the service() method, for whatever reason that might happen. To say nothing of returning the connection to the connection pool you got it from. That is exactly what the filter will do for you. The transaction wrapup in the filter will ALWAYS be called = less scope for errors. Is there some recognised way to pass servet/jsp error conditions to filters? This would prevent me relying on exceptions (altho' exceptions would have to be catered for too). I suppose I could use the request.getAttribte()? Are exceptions that are trapped in a filter 'seen' and handled by Tomcat? Your problem is that Tomcat sees the exception thrown by the servlet before it is passed back to the filter. That's where the logging is happening. And that's not going to change (in the standard Tomcat release -- you're perfectly free to modify your own copy), because handling exceptions is not what filters are for. Oh no it doesn't. Otherwise filters could not work. If you put doChain() in a try catch block, you catch the exception that the jsp/servlet threw. TIA - Mark Craig I'll second what Craig has said and add that if your program normally throws lots of exceptions, then you should look at some of your design decisions. Exceptions are wonderful when used for Exceptional behavior, but not for normal runs. They are also REALLY slow. Exceptions can kill your performance, and if you are getting them regularly, you should catch the ones you can safely ignore as early as possible and toss them away as appropriate, or even better, not throw them at all.

The point I was trying to make was that exceptions are not only a sign of system failure, but one of usage failure too. Yes, which means that if you can trivially check your parameters before calling a routine that will throw an exception because of those parameters, it is cheaper than letting the routine throw the exception and then catch it. Anyway, what I was trying to do was to implement a transaction logging filter that determined if a particular database write operation had worked. The code is simple and checks if a servlet/jsp has thrown an exception to check for success/failure. If the servlet/jsp completes without throwing an exception, I commit the transaction, otherwise I roll it back. To be really blunt, this is exactly the behavior tha the J2EE servers gives you. The EJBs can be transaction ignorant and the overall transaction will be committed/rolledback as appropriate. The key here, though, is most of these exceptions shouldn't be logical exceptions (particularly if there are a lot of them), but rather physical exceptions (database full, integrity check error). Exceptions for circumstances that are basically out of your control. As a simple example, we have found, at least with a J2EE environment, that it would be cheaper to, say, check that a user didn't exist in a DB with simple SQL rather than insert a row dependant on that user and throw the foreign key exception back.

[Answer to]: JSPs in Tomcat 4.0.x: NoSuchMethodException in TldLocationsCache
Hi all, After struggling a bit with Tomcat 4.0.x (It took enough time to try w/ 4.0.1, 4.0.3 and 4.0.4), I think I've got the ANSWER to the infamous NoSuchMethodException thrown in TldLocationsCache when you try to run jsps in Tomcat 4. I'd like to apologize if this is old news, but browsing the forums (even there are postings in the Bugzilla list) I think people are still clueless (either that or they find out and then shut up). The problem has nothing to do with the SDK version or the Tomcat installation or version. (These seem to be the most popular hypothesis I've seen). The problem is the version of the servlet.jar library. If we take a look at the code for the method processJars () at class TldLocationsCache (the apparent culprit of the exception) we'll see the line: Set libSet = ctxt.getResourcePaths(/WEB-INF/lib); Where ctxt is a reference to an object implementing javax.servlet.ServletContext. (The rest of lines in the method are innocent enough to cause trouble) The method Set getResourcePaths (String path) is new in the servlet 2.3 spec and therefore is missing from previous releases. This is the key!! If you download the current servlet spec jar (or zip file as Sun has it at java.sun.com) and place it on your classpath BEFORE (or even better replacing) any reference to olders servlet.jar files, that should do the trick (At least it did it for me :) Now, I think I've got it running nicely.

I'm trying to execute a unix command from within the jsp page, smth like

dat.foo});
.. And it doesn't work, I mean nothing happens , no error messages,

Well, if the ls -l happens to not find the file foo.dat, then it's proper
result would be to, essentially, do nothing. So, perhaps it actually is
working, and the file you're running 'ls' on isn't there?
P.S. just an FYI, but you do realize that the java.io.File object does
pretty much what 'ls' will do for you, right? Plus, it's portable...

You can accomplish this for a particular servlet by throwing an exception from the init() method, but there is no portable mechanism to do this for an entire webapp. Conceptually, throwing an exception from a configured listener class (like a ServletContextListener.contextStarted() method) would make sense. More formal definition of the semantics of this is under discussion for Servlet 2.4. This servlet would be flagged as load-on-startup such that it was the first one to execute. I'm trying to achive something similar to JBoss 2.x where if the verifier fails for an EAR, it does not deploy it at all. I want the similar concept but for my Web Application, such that critical initialization errors make the the whole application unavailable. I can't find anythingin in the Java Servlet Spec to indicate that this is possible, or anything in the tomcat documenation. In Tomcat 4.0.x and 4.1.x, throwing an exception from contextStarted() will indeed abort the deployment of that webapp, but this is Tomcat specific. Thoughts?

RE: How to abort the webapp load/deployment
You could uild a MVC app where there are no page accesses that don't pass through the controller (i.e. index.form and form is mapped to a servlet which does a requestDispatcher to index.html or index.jsp). Have the controller only pass people through if the validation has occured successfully.

JBoss_Tomcat: No Context configured to process this request
Version: jboss-3.0.0_tomcat-4.0.3 OS: Redhat 7.2, 2.4.7-10 I'm moving my existing Apache-based web server over to a Jboss/Tomcat combination. I need to set it up to vhost 3 domains. The JBoss/Tomcat installation is an out-of-the-box binary. I added three entries to the catalina/conf/server.xml (as I have done in the past for vhosting on a Tomcat-only server) like this: Host name=domain1 Context path= docBase=webapps/domain1//Host But this is inside the Tomcat-standalone Service tag. Do I need to configure a different Service tag for a JBoss/Tomcat setup? After the install, I ran $JBOSS_HOME/bin/run.sh and it seemed to invoke all of the JBoss and Tomcat stuff fine. I can hit the server remotely but I get HTTP Status 500 - No Context configured to process this request. I deployed a test servlet using ant to $JBOSS_HOME/server/default/deploy and JBoss picked it up and hot deployed it, no problem. I have static content for two of the domains to-be-hosted that I would like the default servlet to handle as it would in a typical Tomcat install. So, (1) How can I setup Jboss/Tomcat to vhost the three domains? (2) How can I get rid of the No Context messages? (3) How can I setup static content (HTML files) to be delivered in a JBoss/Tomcat scenario?

Hi Shanmugampl. Thanks for your answer. I've had some progress since my last mail. I can now compile the part of the mod_jk connector that ANT is responsible for, i.e. the jar files. The problem was that servlet.jar was missing in the CLASSPATH. But now I have a new problem, according to the documentation I've found, after building the jar files with ant, I should run ant install. The problem is that ant then complains Target 'install' does not exist in this projekt. Any idea why this is the case?

Inquiry on JSP Loading
** High Priority ** Hi, I'm from an audit department working for a local bank in Singapore. I am currently researching on the benefits of using JSP for developing my department website but encounters several problems. I've been following very closely on every documentations in regards to the setting up of Tomcat server as well as JSDK and JRE. I've managed to get the Apache Tomcat server up and running at the localhost port 8080 after modifying catalina.sh. However, when I try to connect my sample JSP page to mySQL database to retrieve data, there is always a connection timeout error. I thought that it might be some class loading error and I downloaded mm.mysql driver and unjar it to /usr/local/jsdk1.4.4/lib and declare the class path in setclasspath.sh under the Catalina home directory. Are you able to advise me on how to properly configure the class path and advise on the timeout error ? Thanks a million !!

Multiple HttpServletRequest objects
Is it possible to have more than one HttpServletRequest object per
session? I am trying to store a request from one form as a session
object, process an intermediary form, and then pass the original request
to a servlet. I have a couple clunky ways of doing this (having the
servlet write a hidden form from the request object and passing this
along). I tried to create a session object like...
protected void doPost(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, java.io.IOException {
HttpSession session = request.getSession();
session.setAttribute(form_data, request);
...and test the original value with...
protected void doGet(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, java.io.IOException {
HttpSession session = request.getSession();
HttpServletRequest old_form =
(HttpServletRequest)session.getAttribute(form_data);
String a_field = old_form.getParameter(textfield);
to see if I get the original field value for the form field called
textfield, but I get a null value. Does anyone have any clever ways
of storing a request object and then submitting later in the session?
Best regards to all!

Re: Replacement of IIS
Few things you need to keep in mind if you do decide to migrate from IIS to Tomcat. 1) With Tomcat, you will not be able to serve .asp pages. You will need to convert them to jsps. 2) Frontpage cannot connect to Tomcat as IIS does. But you will be able to use the editing capabilities of FrontPage. You could still edit HTML pages. 3) Although Tomcat could be used standalone, it would be a good idea to use Apache as a webserver to serve static pages (using mod_jk), and let Tomcat handle the dynamic (jsp) pages. mod_jk has load-balancing capabilities as well. 4) Or you could still use IIS as the webserver (this way you don't loose the asp functionality). And let Tomcat handle the jsps (and servlet). You could an ISAPI dll to connect IIS and Tomcat.

mod_jk target problem.
In our mod_jk.conf we've only got a couple of paths used for JkMount, but mod_jk still seems to be handing off everything from / to tomcat. We're using Tomcat 3.2.3 and mod_jk 3.2.3. We'll be upgrading, but that's not for a little bit yet, unless this can be fixed by upgrading. We use Apache 1.3.24 on Linux. Any help on this problem is appreciated.

Re: Tomcat 4.1.7 admin appliaction problem
Hi James, You have to have a security realm set up to use the manager. Just a shot in the dark but that may be your problem.

RE: mod_jk target problem.
If you are mapping: JkMount /myapp/* ajp13 Then it will forward all requests for http://mysite.com/myapp/... to Tomcat. To avoid this map: JkMount /myapp/*.jsp ajp13 Or: JkMount /*.jsp ajp13 This way only requests for jsp files will be forwarded to Tomcat and everything not specified will be picked up by Apache.

RE: Multiple HttpServletRequest objects
The answer about HttpServletRequest objects is probably no, but
it sounds like you need a java bean. Use the bean to store your
form data (one bean per form might be the cleanest). Then once
you've validated all the input from all the forms you can do
whatever it is you're attempting to do.

Subject: Multiple HttpServletRequest objects
Is it possible to have more than one HttpServletRequest object per
session? I am trying to store a request from one form as a session
object, process an intermediary form, and then pass the original request
to a servlet. I have a couple clunky ways of doing this (having the
servlet write a hidden form from the request object and passing this
along). I tried to create a session object like...
protected void doPost(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, java.io.IOException {
HttpSession session = request.getSession();
session.setAttribute(form_data, request);
...and test the original value with...
protected void doGet(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, java.io.IOException {
HttpSession session = request.getSession();
HttpServletRequest old_form =
(HttpServletRequest)session.getAttribute(form_data);
String a_field = old_form.getParameter(textfield);
to see if I get the original field value for the form field called
textfield, but I get a null value. Does anyone have any clever ways
of storing a request object and then submitting later in the session?
Best regards to all!
Aaron

Prblm: ant install fails after building mod_jk jars for tomcat-4.0.4 connectors.
Dear subscribers. I have a problem regarding the ant install part after I've built the jk (AJP13) connector for jakarta-tomcat-connectors-4.0.4. When I run ant install I get an error message Target 'install' does not exist in this project. Any idea why this is the case? The preceding build process seems to work fine.
