Re: Best Logging practices
Without an intent to offend anyone, I'd say majority of the posts were centered around what tools to use, rather than the best practices itself (apart from the posts of Jacob and Peter Lin). So, from what I understand: 1. Web applications written using tomcat should have the logging path configurable (via the parameters in the web.xml, for example) - since the webapp can be run directly from the .war archive. And Steve had a remark about not being able to have configurable files inside the jar. 2. While logging to a directory inside the webapp structure, its a good practice to check context.getRealPath(/) returns non-null first. 3. Keep an alternative - so when logging to your file fails, use ServletContext.log(string) to send the message string to application log. What about, like Peter mentioned (but did not quite elaborate) log rotation? report generation based on logs? log backups? Also guidelines for the developers to separate the log messages that are errors, and log messages that are produced by the application as indications of the outcome of some task?

Re: Best Logging practices
I agree. When I posted that, it was a summation of the posts that I had seen till that time. What I've been looking for is a standard way to configure my .war archives, such that we can call it a true deployable - without any interference from the users. Like someone else pointed out, the intent is to make have configuration free archive. I've had several instances in the past, where despite the best efforts, we ended up having to provide instructions to the end-user for deployment (and the worst is one you ask the end-user to open up the web.xml or some application-specific properties file that the applications reads from). Further, there are instances where certain servers do not explode the .war archive, so the end-user never gets to see those properties files themselves.

Re: Best Logging practices
Hi Peter, Thanks a lot for the response. here are some other considerations. For some of the projects I've worked on in the past, there were established directories for logs. Therefore I used log4j to write my logs asynchronisly. Could you elaborate on established directories? I assume these directories were within your webapp context. If yes, then what if the application is deployed onto a server that does not explore your .war file? Secondly, there are instances where, thought the application is deployed correctly, there are no write permissions to that directory - how did you resolve such a situation? Finally, at times there are log files that are generated as a result of certain user action, not necessarily errors, but these have to be made available to the user as information. Would you store them into the same directory as other log files? Then there are other issues of such log files increasing in size and number continuously, and log rotation as well as backup. Any ideas about that? logging isn't as simple as write stuff to file. You have to take into consideration other things like how are the logs backed up, when are reports generated, and other system administration processes. Oh, I agree to that. Since the advent of Log4J, I've seen the logging process to be more standardized, and the though there might be one-off incidents of literally anything being logged, there is some level of sanity. Though yes, log backup, report etc still are prevalent issues. I typically stick configuration information in web.xml, if the application is meant to be a deployable web app in .war format. one thing to keep in mind is what happens if your log fails, you will want to direct the exceptions to the application log by passing it to ServletContext.log(string). In some situations, system administrators at the customer's facility insist they should know what directories your application shall write to, and that this directory can be changed, if required for them (say, you develop the application and its deployed on a cluster, and they might want to change this path). You might stick this path in web.xml but then again, there is no guarantee the web app will be exploded.

Tomcat security configuration guide
Hi, I have begun to work on a tomcat security configuration guide as a one-stop guide for helping system administrators, security professionals and programmers to configure system user accounts and groups, file permissions, tomcat security realms, java security manager, etc in the optimal way thereby ensuring their system is not vulnerable to common security exploits. 1. Has this already been done? If yes, can someone share the document/URL where I can find more information? 2. Will there be professionals/enthusiasts out there to contribute/critique? 3.

Re: WAR Problem - No Go
Hi Eric, I'm not sure what has happened. I see two things in error.log that you posted: 1. tomcat tries to remove the child while shutting down, and gets an error that the context /apress has not been started yet. 2. while starting up, tomcat again tries to bring up the context /apress but encounters an error while trying to configure resources, and does not load the context. Also, you mentioned you have that context mentioned in the server.xml - i don't think you need to do that. maybe, while starting up, tomcat sees that context in server.xml and tries to load it and finds nothing and fails. when it next finds the apress.war maybe it doesn't load it since it assumes that a context with the same name had to failed to start. could you try cleaning up your work folders, removing the entry from the server.xml about the context apress and try again? ~manav. - Original Message - From: eric [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Sunday, January 19, 2003 1:45 AM Subject: Re: WAR Problem - No Go Mark, Tried that and it still didn't work.

Re: WAR Problem - That was it
Well, AFAIK, each directory in the webapps folder is treated as a context, and tomcat searches for web.xml inside the WEB-INF folder (if not found it uses the default web.xml - i'd like the experts to interject, if i am mistaken). so, the assumption of your program running without a context is not valid - there is indeed a context created for your application. You need to create a context specifically in server.xml if you want some default initializations to happen - configuration of datasources for example, prior to the context loading. most applications, while being deployed, do not need an explicit context (again, i suggest you also read up the opinion of other experts on the list - i'm not that good at tomcat, yet). ~manav. - Original Message - From: eric [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Sunday, January 19, 2003 6:49 AM Subject: Re: WAR Problem - That was it Manav, Your suggestion did the trick.

Re: Tomcat Won't start on NT
This problem of running tomcat 4.1 and above, with JDK 1.4 and above has
been documented (and quite well too) at
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/class-loader-howto.html
(scroll down to the section XML Parsers and JDK 1.4).
In essence, the conflict is caused by the built-in JAXP parser supplied with
JDK1.4 and the one you are trying to use for your application. You can still
use JDK 1.4 or above, but you'd need to set the parameter
java.endorsed.dirs, while installing the application.Read
http://java.sun.com/j2se/1.4/docs/guide/standards/index.html for more
information.

I think you can still use JDK 1.3 but I'd reccommend using 1.4.
How you get this to work on JDK 1.3, I'm not sure... you can start by
trying
to get an XML parser implementation (like Xerces) and either put that
somewhere in your classpath or (better yet since I hate the global
classpath)
put it in your {TOMCAT_HOME}/lib directory.
I don't know if it's enough to just put it there but at least it's a
starting
point. You may need to configure some things but I don't know more about
that. I seem to recall reading that you need to remove the jaxp.jar and
parser.jar files when you put xerces.jar instead so the classloader
doesn't
get confused.
Go ahead and try that and let us know how it works out.
Regards, Stefan.
p.s. don't completely delete the jaxp.jar and parser.jar files... just
move
them somewhere temporarily since I only vaguely remember reading this...
this
might not even be neccessary at all.

Common problems faced with tomcat configuration
Hi, In the past several months that I have been in the list, I have seen the following problems faced commonly by the users (new or old): 1. Configuring DataSource with tomcat 2. Configuring tomcat to run with apache (using AJP or JK2) I would like to know if there is anything being done to make it easier for the new users to get around these bottlenecks. Also, I am sure there are a number of experienced users on this list who have successfully done the two things above, and I would request them to post the steps for a successful configuration. We can then collaborate and post a better documentation to configure these. Finally, I would also like other users to contribute to this (small) list above, the problems they think have been faced commonly and repititively by tomcat users, so that we can strengthen the documentation for those too.

tomcat in production mode
Hi, What are the steps/precautions that should be taken to run tomcat 4.1.x in production on windows (apart from running it as a service, and turning auto-compilation of JSP pages off)? Is there a checklist of standard practices out there? Regards, Manav. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: learning filters
I wrote a simple filter for authentication:
public void doFilter(ServletRequest request,
ServletResponse response, FilterChain next)
throws java.io.IOException, javax.servlet.ServletException {
// HTTP request and response that we work with.
HttpServletRequest httpRequest = (HttpServletRequest) request;
HttpServletResponse httpResonse = (HttpServletResponse) response;
HttpSession theSession = httpRequest.getSession();
if ( (userid != null password != null)
(selectedURL.equals(login.do)) ) {
next.doFilter(request, response);
} else if ( (theSession.getAttribute(firstname) == null) ) {
LoginJSPData loginJSPData = new
LoginJSPData(MessageKey.BAD_SESSION);
ServletContext context = this.filterConfig.getServletContext();
context.getRequestDispatcher(/badlogin.jsp).forward(request,
response);
} else
next.doFilter(request, response);
} // end doFilter
1. Is it a good idea to do so?
2. The filter mapping tag in the web.xml now looks like:
a. filter-mapping/*/filter-mapping
b. Would this not slow down the application, since in a standalone scenario,
all request for images will also go through the filter?
Regards
Manav.

Subject: learning filters
I have been learning about servlet programming from Core
Servlets. I like
this book. But, since subscribing to this list, I have seen mention of
filters. In a message from Yoav Shapira I was recommended to use
filters to validate form data before passing it to a servlet.
This seems
to me a cleaner means of doing it, as opposed to putting form-validation
code in the servlet. However, Core Servlets does not describe
how to use
filters (that I know of). Is there a reference for this technique
somewhere, or is it a generic term for a servlet that intercepts, acts
upon, and passes along data ? If it is the latter then I can
figure it out
from using getDispatcher().forward() etc but if it is a specific technique
then where can I learn more?
My Tomcat container is v. 4.0.6.

Greetings,
I find a way of put it to work (tested on 4.0.4, 4.1.2).
I put the Resource inside a *DefaultContext*. I couldn't put it to
work inside a specific context or even through a resourceLink to a
global resource.
Now, I don't know why is that happens! I'm deploying in war file, and
apparently my context element I put in server.xml isn't mapping
resources right:
context docBase=ngincare.war debug=0
reloadable=true
path=ngincare
{Resource+ResourceParam|ResourceLink}
/context
If you could explain this, it would be just fine! For now I'll use the
DefaultContext...

Hi,
Can somebody point out my mistake for me - I'm starting to bang my
head..
I am trying to get connection pooling working on my AS/400 using the
Commons-DBCP.
I have placed this JAR in TOMCAT_HOME/common/lib along with the
JT400.JAR
I have added the context entries to my server.xml file - thus:-

Thanks for the reply. How do i make it a global resource? Just declare the
resource in the global section?

I've not done it myself in tomcat, only in EJB containers, but as a starting
point, I would suggest trying to get it to work by setting the connection
pool as a global resource instead of a resource specific to your context.
Then try and get your context-specific connection pool working.
I too am surprised by the number of people facing this problem.

RE: Connection Pooling Help
No, i am not using apache - its a standalone version of tomcat.
To be honest, I find it rather awkward to be worried about the mod_jk
versions, or whether i have a paricular module installed or using a
particular connector, etc. With a tool being into such a wide use, I'm sure
there are people who have done this before, but somehow, either I am missing
something significant, or maybe others went through the same ordeal and have
been unable to reproduce what they did, or maybe its just dumb hard luck!

The main problem if you are using apache or not, is the connector. I
don't
know if you are using apache but if you are using apache with tomcat DON'T
USE
the WebApp connector, is not maintained anymore and does not work correctly
with
apache 1.*, 2.*. USE mod_jk2 it works fine with the pool connection. I had
the
same problem a few days ago and I resolve the problem changing connectors.
I hope this help.

Greetings,
Eric, I'm getting a javax.naming.NameNotFoundException: Name jdbc is
not bound in this Context exception!
I have a resource link inside my context (no resource here or
resource-ref in web.xml):
resourceLink name=jdbc/ngincaredb
global=jdbc/ngincaredb_global
type=javax.sql.DataSource /
and I'm doing a lookup in my code for jdbc/ngincaredb:
Context initCtx = new InitialContext();
Context envCtx = (Context)initCtx.lookup(java:comp/env);
this.ds = (DataSource)envCtx.lookup(/jdbc/ngincaredb);
So, what's wrong here?
thanks,
Pedro Salazar.

Pedro,
You need javax.sql - that is the package containing DataSource.
Your Resource type should be: type=javax.sql.DataSource
You need these parameters in addition to url, username and password:
parameter
namedriverClassName/name
valueoracle.jdbc.driver.OracleDriver/value
/parameter
parameter
namefactory/name
valueorg.apache.commons.dbcp.BasicDataSourceFactory/value
/parameter
In the Context the ResourceLink type should be:
type=javax.sql.DataSource
You do not need any resource-ref in your web.xml - just use your
ResourceLink name as follows:
Context ctx = new InitialContext();
Context envCtx = (Context) ctx.lookup(java:/comp/env/);
DataSource ds = (DataSource) envCtx.lookup(/{name_of_resource_link});
if (ds != null) {
DbCon = ds.getConnection();
}
Hope this helps.

RE: Tomcat 4.1, DBCP and Oracle
Oracle has changed the driver class for version 1.1x to 1.2. In 1.1x it was oracle.jdbc.driver.OracleDriver while in 1.2 is oracle.jdbc.OracleDriver - so use the driver depending upon the version you are using (you can unjar/unzip and you'd find what class you really have).

newbie: Realm
Hi, Like all web applications, I need to provide some kind of session maintenance. Would the concept of a Realm help in this? 1. Is this the correct application/use of a realm? 2. Is a realm akin to a SSO/LDAP server, where the user's roles and mapping to actions is stored? 3. How extensible is a realm? Can someone provide a step-by-step example of how to setup and use a realm? Manav. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Re: Problems running Tomcat from command line
Hi, All your problems stem from the lack of environment space. If you run this on '95/98 you'd get the same error. While running tomcat, do you really need to have such a long path (as specified)? You could write a small batch file to keep the path to the bare minimum - this way you'd have more space for initialization of tomcat. this is a temporary solution - since most of the jar files you'd come across force you to include them in the classpath.

Subject: Oracle thin client DataSource configuration with tomcat
Hi,
I'm sure the gurus have discussed this issue a number of times and
probably
found a solution too, but after reading all the documents i found, i
came
to
a naught.
Its the same problem: server.xml and web.xml seem to have been
configured
properly, yet when i try to obtain a datasource i get nothing.
Here's the scenario:
setup: tomcat 4.0.3 LE, jdk1.4, RHL 7.3

String foo = Not Connected;
String bar = ;
javax.naming.Context ctx = new javax.naming.InitialContext();
javax.naming.Context envCtx = (javax.naming.Context)
ctx.lookup(java:comp/env);
if(ctx == null )
throw new Exception(Boom - No Context);
javax.sql.DataSource ds =
(javax.sql.DataSource)envCtx.lookup(jdbc/RtiDB);
if (ds != null) {
java.sql.Connection conn = ds.getConnection();
out.println(got a connection);
}
out.println(no luck yet);
%
And I never get the message got a connection. Any clues?
Btw, I have not touched the Realm - I don't understand what that is
meant
for. Not yet.
TIA,

Subject: Oracle thin client DataSource configuration with tomcat
Hi,
I'm sure the gurus have discussed this issue a number of times and
probably
found a solution too, but after reading all the documents i found, i
came
to
a naught.
Its the same problem: server.xml and web.xml seem to have been
configured
properly, yet when i try to obtain a datasource i get nothing.
Here's the scenario:
setup: tomcat 4.0.3 LE, jdk1.4, RHL 7.3
server.xml
!-- RTI Billing Context --
Context path=/rti docBase=rti debug=0
reloadable=true crossContext=true
Logger

String foo = Not Connected;
String bar = ;
javax.naming.Context ctx = new javax.naming.InitialContext();
javax.naming.Context envCtx = (javax.naming.Context)
ctx.lookup(java:comp/env);
if(ctx == null )
throw new Exception(Boom - No Context);
javax.sql.DataSource ds =
(javax.sql.DataSource)envCtx.lookup(jdbc/RtiDB);
if (ds != null) {
java.sql.Connection conn = ds.getConnection();
out.println(got a connection);
}
out.println(no luck yet);
%
And I never get the message got a connection. Any clues?
Btw, I have not touched the Realm - I don't understand what that is
meant
for. Not yet.
TIA,
Manav.

Fw: Oracle thin client DataSource configuration with tomcat
Hey Gurus,
any ideas what could be the problem? following are the settings (revised):
server.xml:
Context path=/rti docBase=rti debug=4 reloadable=true
Logger className=org.apache.catalina.logger.FileLogger
prefix=rti_log. suffix=.txt timestamp=true /
Resource name=jdbc/rtidb auth=CONTAINER type=javax.sql.DataSource
/
ResourceParams name=jdbc/rtidb
parameter nameuser/name valuerti/value /parameter
parameternamepassword/namevaluerti/value /parameter
parameter namedriverClassName/name
valueoracle.jdbc.driver.OracleDriver/value /parameter
parameternamedriverName/name
valuejdbc:oracle:thin:@rti:1521:rti/value/parameter
/ResourceParams
/Context
web.xml:
web-app
resource-ref
res-ref-namejdbc/rtidb/res-ref-name
res-typejavax.sql.DataSource/res-type
res-authContainer/res-auth
/resource-ref
/web-app
test.java
Context ctx = new InitialContext();
if(ctx == null )
throw new Exception(Boom - No Context);
Context envCtx = (Context) ctx.lookup(java:comp/env);
DataSource ds = (DataSource)envCtx.lookup(jdbc/rtidb);
System.out.println(DataSource: + ds);
if (ds != null) {
Connection conn = ds.getConnection();
}
- DataSource is always null.
(excerpt) thread dump of catalina:
XmlMapper: org.apache.catalina.deploy.ContextResource.setName( jdbc/rtidb)
XmlMapper: org.apache.catalina.deploy.ContextResource.setType(
javax.sql.DataSource)
XmlMapper: org.apache.catalina.deploy.ContextResource.setAuth( Container)
XmlMapper: Calling org.apache.catalina.core.StandardContext.addResource

scope=Shareable]
XmlMapper: pop resource-ref org.apache.catalina.deploy.ContextResource:
ContextResource[name=jdbc/rtidb, type=javax.sql.DataSource, auth=Container,
scope=Shareable]
Any clues?
TIA,

Re: Oracle thin client DataSource configuration with tomcat
I always get the line no luck yet (as printed in the JSP page). The
dataSource is never created.

What happens when you attempt to refrence the JSP from a browser ? The
connection pool with Oracle is not established until a JSP which uses the
pool is requested.
