Re: JTDS help
I do not think, jsp compilation is the problem - well, the first request
will last long, but after the jsp is compiled, subsequent calls will not
be remarkable slower than executing pure compiled servlet code.
(Charles, I hope you did not measure the time for the first request only
- which indeed includes compilation time, but for subsequent calls too).
So to me opening the connection is the major problem. Because the code
itself contains html-output, I think using jsp is quite ok.
The code would be much cleaner, if Charles used the JSTL tag-library:
<%@ page language="java"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"; %>
<%@ taglib prefix="sql" uri="http://java.sun.com/jstl/sql"; %>
Best regards,
Tex

Ok. You're doing this in a jsp. That means Tomcat is:
1) Compiling your jsp to a servlet class.
2) Building a connection from scratch as opposed to picking up a
pooled connection
3) Running the query.
Of these, the first one is the most expensive operation followed by
two. If you want fast, try
doing this with a pooled connection and from compiled servlet code.

There's no real reason relating to Tomcat or jTDS that this would run

I think the main time is spent on opening the database connection!
So you better use connection pooling - then this expensive operation is
just execute once (or at least not so often)
Have a look at the Tomcat documentation (Section on JNDI-DataSources)

Re: [SOLVED] Form Auth + xml users database
Hi! I'm happy you could solve your problem now! Seems the reason was the missing Realm-definition in your context.xml. To Question 1) Tomcat offers a separate JNDI-namespace for each web application (so if you have 4 web applications you will have 4 namespaces). These namespaces are configured in the -elements of the corresponsing web-applications. To define resources, you have to nest a -element in your -element (which should be in context.xml). A resource that is defined in the namespace of a web application cannot be seen by other web applications (because the namespaces are separated from each other). Sometimes, a resource may be required by more than one web application. To avoid configuring this resource several times - once per context - tomcat offers another namespace that is global and exists only once per tomcat instance. If you define a resource there, you can use it in each web application, that is allowed to use it. So how can you allow a web application to use a global resource? Simply "link" the global resource into the local JNDI-namespace of the web-application! This can be done by nesting a element in the element of the web-application that should be allowed to use the resource. When defining a -element, you must specify, which global resource you want to link into the namespace (attribut "global"), which type the resource is that you want to link (attribut "type"), and which name it should have in the local namespace (attribut "name") - this name can be equal to the global name. So the server.xml and context.xml hierarchy could look like the following (sorry for the "text-art" - use a fixed width font for "best results"): +- Server | +- GlobalNamingResources | +- Resource GlobResA | +- Resource GlobResB | +- Service +- Engine +- Realm X +- Host www.A.org | +- Context /A1 (defined in context.xml) | | +- ResourceLink to GlobResA, name: LocResA | | | +- Context /A2 (defined in context.xml) | | +- ResourceLink to GlobResA, name: LocResA | | +- ResourceLink to GlobResB, name: LocResB | | | +- Context /A3 (defined in context.xml) | +- Resource, name LocalResA | +- Host www.B.org +- Context /B1 | +- ResourceLink to GlobResA, name: LocResA | +- Context /B2 +- ResourceLink to GlobResB, name: LocResB Question 2) If you do not want to change server.xml (e.g. because you want to deploy your application to a foreign server and you cannot modify server.xml there), you could define a local JNDI-Resource in the -element of your web-application instead of the GlobalNamingResource (simply move the resource-definition from into your -element). If you do this, of course you do not need the any more! So you do not have to touch server.xml because all configurations can be done inside context.xml which is in the meta-inf directory of your web application. I hope, my explanations where understandable!

You are right! I'm sorry for any confusion!
I thought is just for environment variables (similiar

Nevertheless, I think this resource reference is not required for

Re: tutorial for fast settings of Tomcat
Hi!
Adding a context.xml is a nice thing and every good web-application
should have one, but it is not required if you just want to have a
simple working web-application - you even do not need a web.xml!. All
you need is a WEB-INF directory inside your context-directory. As soon
as tomcat's auto-deploy-mechanism detects a WEB-INF directory, the
manager-application displays the web-app ("available"-flag is "true").
Best regards,
Tex

Hi!
If you are already familiar with programming JSPs
and you just want to
know what you must do to set up a web-application
that can handle JSPs -
you're glad, because that is almost done.
Have a look at the tomcat-docu at
http://localhost/tomcat-docs/appdev/index.html
In short:
1) create a directory below %TOMCAT_HOME%/webapps
The directory you've created is the root-directory
of your
web-application's context.
(For the next steps, I assume the name of the
directory is "test".)
2) create a directory "WEB-INF" below
%TOMCAT_HOME%/webapps/test
This is the directory that contains all the settings
of your
web-application.
That's it! Now you can put your jsp-files inside
your web-application's
context directory (%TOMCAT_HOME%/webapps/test) or
any subdirectories
except "WEB-INF". (This is the only directory, that
is never accessible
from outside).
You do not need to restart Tomcat if auto-deploy is
enabled (which is
the default setting).
You can access your files using a web browser via
the url
"http://:/test"
(if you are sitting in front of the computer, tomcat
is installed on and
you use default installation without overriding the
port:
http://localhost:8080/test)
3) [optional] If your JSPs need any classes or
libraries that are not
part of the JDK or Tomcat/commons (e.g. self-written
classes etc.), do
the following:
+ put classes inside WEB-INF/classes/
+ put libraries (.jar-files) inside WEB-INF/lib
The WEB-INF/classes directory and every jar-file
inside WEB-INF/lib will
be in the scope of your web application's
classloader.
4) [optional] If you want to have more control over
your
web-application, write a deployment descriptor:
Create a file "web.xml" in
%TOMCAT_HOME%/webapps/test/WEB-INF. (your
deployment descriptor)
http://java.sun.com/xml/ns/j2ee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";

Re: tutorial for fast settings of Tomcat
Hi! If you are already familiar with programming JSPs and you just want to know what you must do to set up a web-application that can handle JSPs - you're glad, because that is almost done. Have a look at the tomcat-docu at http://localhost/tomcat-docs/appdev/index.html In short: 1) create a directory below %TOMCAT_HOME%/webapps The directory you've created is the root-directory of your web-application's context. (For the next steps, I assume the name of the directory is "test".) 2) create a directory "WEB-INF" below %TOMCAT_HOME%/webapps/test This is the directory that contains all the settings of your web-application. That's it! Now you can put your jsp-files inside your web-application's context directory (%TOMCAT_HOME%/webapps/test) or any subdirectories except "WEB-INF". (This is the only directory, that is never accessible from outside). You do not need to restart Tomcat if auto-deploy is enabled (which is the default setting). You can access your files using a web browser via the url "http://:/test" (if you are sitting in front of the computer, tomcat is installed on and you use default installation without overriding the port: http://localhost:8080/test) 3) [optional] If your JSPs need any classes or libraries that are not part of the JDK or Tomcat/commons (e.g. self-written classes etc.), do the following: + put classes inside WEB-INF/classes/ + put libraries (.jar-files) inside WEB-INF/lib The WEB-INF/classes directory and every jar-file inside WEB-INF/lib will be in the scope of your web application's classloader. 4) [optional] If you want to have more control over your web-application, write a deployment descriptor: Create a file "web.xml" in %TOMCAT_HOME%/webapps/test/WEB-INF. (your deployment descriptor) http://java.sun.com/xml/ns/j2ee"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"; version="2.4"> Test application Test application Best regards, Tex P.M schrieb: Hi, I'm new to tomcat server for JSP and i'm reading for now a very huge book for knowing how to configure tomcat 5.x to make WEB JSP application works correctly.

Re: order of creation of JNDI datasource from context.xml and Filter.init() using it
Hi Jeroen! Two weeks ago I (almost) exactly did what you want to do - make hibernate use a JNDI-DataSource defined as a GlobalNamingResource! The differences: My database is Oracle and I didn't configure hibernate directly because I use the spring-framework in between. I experienced problems similar than yours, but after cleaning out some "old" stuff it worked! Unfortunately, I do not know, what exactly the problem was, but I can give you some hints that may help you! Assuming you use Tomcat 5.5, do the following 1) Skip the "factory"-attribute in your Resource-definition! It is not required because tomcat has a built-in connection pool and automatically uses it for JNDI-DataSources. 2) Define your JNDI-DataSource in the GlobalNamingContext 3) The -element in meta-inf/context.xml must specify the name of the global resource (attribute "global") AND the name, the resource should have when linked into the lokal JNDI-context (attribute "name"). This (internal) name must match the name specified in your hibernate config! I guess that's what you got wrong! Your code: (You specified "My Database" as internal JNDI-name, but jdbc/mydb in hibernate.cfg.xml!!!) Better: (That matches the name you used in your hibernate.cfg.xml: "java:env/jdbc/mydb") 4) Remove the context-definition file in conf//. At deployment time, tomcat copies the context.xml file from the meta-inf-directory of your web-application into the conf//-directory (and renames it to avoid conflicts). 5) The PostgreSQL-driver must be in common/lib. Make sure it is NOT in WEB-INF/lib too! As I've said in top 3, I think the chief cause of your problem is the resourcelink-element! (Apart from that: I've seen you wrote your own HibernateSessionFilter. I also did that first, but then I decided to use the OpenSessionInViewFilter from the spring-framework instead. It works great! I'm sure your filter-implementation is not the cause of your problems, but maybe the spring-framework is interesting to you!)

Re: Tomcat 5.5.4/Windows 2000 server - Failed to register in JMX: BasicDataSourceFactory
Hi Greg, hi David!
Sure, there is anoter factory you could use: The tomcat-built-in
datasource factory. Unfortunately I do not know the classname of this
factory, but I think it is somewhere in the library
naming-factory-dbcp.jar which is located in common/lib.
(The Tomcat-guys didn't want to add the complete jakarta-commons-pool
and jakarta-commons-dbcp libraries because most of the classes inside
these libraries are not needed by tomcat. So they extracted the required
classes only and repacked them thogether with some other classes into
naming-factory-dbcp.jar. To avoid confusions and errors, they also
modified the package names - thats why you get a ClassNotFoundException
when you configure the JNDI-context to use the
"org.apache.commons.dbcp.BasicDataSourceFactory").
But I'm not sure if it is a good idea to extend one of those
tomcat-internal datasource factories! This would REALLY tie your code
close to tomcat!
Apart from that: If you implement/extend an existing DataSource factory,
you have to put your implementation inside the common/classes directory
- otherwise tomcat won't find it when it initializes the JNDI-context!
So why not put the commons-pool and commons-dbcp jars into common/lib too?
So my suggestion: Extend BasicDataSourceFactory from commons-dbcp and
put the two jars mentioned above into common/lib.
Best regards,
Tex
Greg Guerin schrieb:
Hi David, Mario,
We actually specify the factory parameter because we extend the
BasicDataSourceFactory so we can encrypt passwords in the resource

factory I'm unaware of? It works fine, but we have to include the jars that
Mario mentioned and it'd be nice to not have to tie our code that close to
the container.

Hi David!
I think, you do not need to explicitely define a bean factory because Tomcat
5 automatically uses dbcp for JNDI-DataSources (I think tomcat looks at the
type of resource - in your case a javax.sql.DataSource - and uses the
tomcat-internal dbcp-factory). In my project, I've configured a
JNDI-DataSource using the Oracle thin driver and it works perfectly without
specifying a bean factory and without adding any special libraries to my
tomcat installation (apart from the oracle database driver which is in
commons/lib).
So try the following configuration:
type="javax.sql.DataSource"
maxActive="20" maxIdle="10" maxWait="-1"
removeAbandoned="true"
removeAbandonedTimeout="60"
logAbandoned="true"
driverClassName="com.ibm.as400.access.AS400JDBCDriver"
url="jdbc:as400://a53pb3;naming=system;libraries=,pgmdbt,caelib;errors=full"

Hi!
How did you define your JDBC DataSource?
As far as I know, the original jakarta-commons-dbcp and
jakarta-commons-pool-libraries are not included with Tomcat. Instead,
just a subset of the required classes with modified package names
(starting with 'org.apache.tomcat.dbcp') are packed in
'naming-factory-dbcp.jar' that can be found in commons/lib.
But if you configure your JDBC DataSource correctly, this should not
bother. Please post you
Re: Problem in war deployment
Hi Doug!
I think eilnet.xml IS the context.xml file you mentioned!
To Manoj: As Dough said, try the following:
1) Remove eilnet.xml from .../conf/{engine}/manoj.eilnet.effectsoft.local
2) Rename eilnet.xml to context.xml
3) Put it into your war-file (into the manifest directory)
Make sure context.xml is configured correctly and that your context is
not configured twice (e.g. in server.xml)!
Best regards,

Parsons Technical Services wrote:
Is there a reason you are using an external eilnet.xml with a war file?
Do you have a context.xml in the war file?
Are you sure the app is not running?
If you find it is then Tomcat is trying to deploy it twice. There are
some notes in the docs on this.
Post the eilnet.xml and the context.xml(if exists). Also post the
server.xml.
Sounds like Tomcat is trying to deploy the app from the war file but
the path info in the context element is wrong. Off the wall guess.
Need to see the files.

Re: Accessing static variable from different webapps
For more information on tomcat's classloading concept have a look at: http://jakarta.apache.org/tomcat/tomcat-5.5-doc/class-loader-howto.html As you can see there, Tomcat instantiates a classloader for each web application. So if you put a class - let's say "Global" - inside the "WEB-INF/classes" directory of each of two of your web applications, it will be loaded twice. As a fact, a static variable of the "Global" class - let's say Global.myVar - will exist twice too! But if you put your "Global" class into the %TOMCAT_HOME%/shared/classes directory ONLY (important: you must remove all occurences of your "Global" class from the webapps-classes directories to make this work!), it will be loaded by the "shared"-classloader. Because of the fact that the shared classloader is the parent classloader of all webapp-classloaders, every web-application can access the classes loaded by the shared classloader. But holding resources in static variables inside the shared/classes directory there is not recommmended! Better add a JNDI-resource to your Tomcat's JNDI-context! This is done in server.xml inside the -element* *(see http://jakarta.apache.org/tomcat/tomcat-5.5-doc/config/globalresources.html). Best regards, Tex Thanks for your reply. I think JVM rules said that there should be 1 reference per JVM for a static variable. Tomcat class loader creates separate instance of a static variable for each webapps.

Re: Hiding resources
Thanks David, I think, your second suggestion will not work, because it is not possible to map a servlet or filter to "*/CVS/*". According to the servlet-specs, only filters of the form "anything/*" or "*.extension" are supported (and I really do not want to add a servlet-mapping for every single CVS directory). I've already thought on a filter using regular expressions for filtering out certain requests. But I'm not sure if this is secure enough. Just think of "modified" request-urls using hex numbers for escaping ascii characters (e.g. ".../%43VS/..." instead of ".../CVS/..."). Are those urls normalized by tomcat, i.e. does request.getRequestURL() return ".../CVS/..." in both cases? Tex Just a thought or two -- 1) Setup a request filter that detects when the URL contains the pattern CVS/ and redirects to a default or error page. -or- 2) Setup a servlet mapping for any of the potential CVS URLs and have them map to a servlet that responds with an error or redirect. --David Mario Winterer wrote: Thanks for your and Nix' advice - I know that what I do is not the clean and nice approach.

Re: AW: Login filter
Hi Ben!
You cannot hook in the login validation process without touching tomcat
code.
But usually, this is not necessary. Just write a filter and map it to
"/" - every request will be directed to your filter - except requests to
"j_security_check". But this should not bother you, because your filter
will be invoked right after a successful login process.
Inside your filter code, check if a certain session-attribute is set. If
not, it is the first time after session creation that your filter is
called. If this is the case, do whatever you intend to do and set the
session-attribute to ensure that your code is only run once.
In pseudo-code (inside your filter's doFilter()-method):
if (request.getRemoteUser() == null) {
// user is not logged in: clear session attribute if set
session.removeAttribute("login");
} else if (session.getAttribute("login") == null) {
// user is logged in but this filter has not been called since
// set the session attribute to avoid that the "special code" above
is called twice:
session.setAttribute("login", "true");
}
Best regards,
Tex
Hi Tim,
Apologies for hassling you again with this.
Any idea without getting inside of the TC source, how I can
write some code just b4 and after the user login validation into the webapp
with using the TC Realm
and j_security_check ?? or must I go inside of the source :-(
regards
Ben
p.s. I got this idea from a ibm websphere help doc, where it is possible !

We are using the tomcat Realm security model, with an Oracle database.
So therefoer I am trying to implement a filter in Tomcat 4.1.27, which
checks for all requests on the url /j_security_check
I know my filter is initialised because I do a out.println
to a logfile. But for some reason when I do a successful login
it doesnt perform the doFilter() method, so I suspect its something
to with the mapping below.
Any hints?

Hiding resources
Hi! I'm running a web application that is under CVS, which means my web application contains a lot of CVS-related directories (for the CVS-metadata). Is there a possibility to tell Tomcat to hide or protect all those "CVS" directories? More general, what I need is a way to hide/protect all files or directories with the name pattern "*/CVS/*". As far as I know, neither a servlet/filter-mapping nor a security constraint support this type of pattern (with two wildcards). So I think, the only way to protect my resources is to implement a custom filter that is mapped against "/" and checks every incoming request. Is there a better approach?

Re: Tomcat 5.5.4/Windows 2000 server - Failed to register in JMX: BasicDataSourceFactory
Hi! How did you define your JDBC DataSource? As far as I know, the original jakarta-commons-dbcp and jakarta-commons-pool-libraries are not included with Tomcat. Instead, just a subset of the required classes with modified package names (starting with 'org.apache.tomcat.dbcp') are packed in 'naming-factory-dbcp.jar' that can be found in commons/lib. But if you configure your JDBC DataSource correctly, this should not bother. Please post your resource-configuration! Best regards, Tex I'm running Tomcat 5.5.4 on Windows 2000 Server and encountered the below error on Tomcat startup: Feb 2, 2005 10:50:49 AM org.apache.catalina.core.NamingContextListener addResource WARNING: Failed to register in JMX: javax.naming.NamingException: Could not create resource factory, ClassNotFoundException:org.apache.commons.dbcp.BasicDataSourceFactory My webapp uses JDBC DataSource's and the BasicDataSourceFactory for pooling so this problem of "ClassNotFoundException" is causing my webapp to not work properly. I have Tomcat 5.5.4 also installed on my local maching which has Windows XP on it, and there is absolutely no problem on startup and and my webapp. Does anyone no what's happening here?

Re: Cross-context
In Tomcat 5.x, you can define the default settings for application contexts in %TOMCAT_HOME%/conf/context.xml. (I'm not sure if Tomcat versions prior to 5.x support this.) Best regards, Tex Tomcat Users - We are distributing a servlet application that relies on the application's element's 'cross-context' attribute to be set to 'true'. Is it possible to set the 'cross-context' in the application's web.xml? This would simplify the configuring of this application for clients as the value could come already configured.

Re: idle connections
Hi! the parameter "maxIdle" is the maximum number of idle connections that can retain in the pool. That means it is ok for the pool to have 50 connections waiting for usage - you told him to do so! So what different behaviour did you expect? Best regards, Tex Hey, wondering if someone could help me out on this. I'm using: Tomcat 5 RedHat Oracle 9i I'm using jdbc and dbcp connection pooling and am trying to tune my app for more scalability. I have my maxActive set to 0 (infinite) and my maxIdle set to 50. When I load test and then look at oracle statistics I find out that there are exactly 50 connections just sitting there inactive. After waiting 2 days they don't go away. I have the removeAbandonded params set to true and 60 seconds but its not "reclaiming" (which I take to mean eliminating) those "inactive" connections.

Re: isUserInRole question

I'm not sure, but I think your code is OK. The question is: How did you

authenticated against the web server.)

Hello,
I am trying to use isUserInRole in an app within
Tomcat. The problem is that I consistently get false

and any help would be great:

out.println( req.getRemoteUser() + "
successfully logged in" );
out.println(req.isUserInRole("admin"));
out.println("-");
out.println(req.isUserInRole("Administrators"));
out.println( "Please submit some form data

Re: sharing session across s
Hi! Do you want to share some kind of global variables or session information? Global variables should exist only once while session information is stored for each user (to be more correct: for each user-session). I think you want to share session-information, but using a class-variable from a class that is loaded by the shared-classloader is nothing else but sharing a global variable. So if you really want to do that: Your solution might work, but it is not recommended. I think using a directory service is the better way! Tomcat has a built-in JNDI context where you can put such global things. (For more information have a look at http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jndi-resources-howto.html). But as I said: All you do is sharing global information that exists only once! Best regards, Tex So... If I create some class, SessionHolder.java, compile it (SessionHolder.class) and put it in shared/lib, I could then set variables and then retrieve them from this class? Charlie Caldarale, Charles R said the following on 2/2/2005 5:00 PM: From: Mark Winslow [mailto:[EMAIL PROTECTED] Subject: Re: sharing session across s I imagine creating a static variable would be global to the JVM. Not quite. It's global to the classloader, not the JVM. Since each web app has its own classloader, you would have to put such a class in a location serviced by a more global loader, such as shared/lib.

Re: compiling and deployment in tomcat
Hi, it is not possible to make Tomcat automatically compile and deploy your servlets. Usually this is not necessary. If you use a good IDE, it is no great effort to compile your servlets. Deployment could be done by using an Ant script - just copy the servlet-binaries in the correct directory and reload your web application (if auto-reloading is disabled). The required Ant-tasks are included in the tomcat binaries. The entry in web.xml must be done by hand, but you have to do that just once. So the cases where auto-compile and -deploy are required are really rare! Best regards, Tex Hi, I've just installed Tomcat 5.5 and I have two main doubts and I hope someone may help me. 1. Do I really have to compile a servlet manually using javac (or using another tool) or may I save it in a specific folder so Tomcat compiles it to me? 2. Do I really have to register my servlets in web.xml file or this process can be done automatically by Tomcat? When I did the test with jsp pages, it was not necessary compile or register the file (Tomcat did everything to me) so I expect the same with servlets.
