HOW DOES TOMCAT JNDI CONNECTION POOLING WORKS
Hi all,
My questing is derived from the sample code given
at :
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-how
to.html#Database%20Connection%20Pool%20(DBCP)%20Configurations
If you can see the subsection 4(i.e. testcode) of section MySQL DBCP
Example,
to get a connection following code is used:
***
Context ctx = new InitialContext();
if(ctx == null )
throw new Exception(Boom - No Context);
DataSource ds =
(DataSource)ctx.lookup(
java:comp/env/jdbc/TestDB);
if (ds != null) {
Connection conn = ds.getConnection();
***
I guess by doing this a connection is obtained FROM THE POOL providing that
a connection is free in the pool.
I have got two questions regarding this-
Q 1. Does tomcat really looks into the pool to get me a connection? or it
just creates
a newone? I am asking this question because I am seeing(using eclipse
debugger)
two connection opened at the same time even after defining
maxActive=1 maxIdle=1 in my application'c context
Q 2. once your database operation is done you free the connection using
conn.close();
by doing this are we pushing the connection back into pool? if not then how
is
pool maintained?
Any help is appreciated

Re: HOW DOES TOMCAT JNDI CONNECTION POOLING WORKS
1. Does tomcat really look into the pool?
Yes. The pool code is really the commons DBCP project code refactored
slightly to avoid collisions with the real DBCP project code.
2. on conn.close(), are we really pushing the connection back into the pool?
Yes.
Sorry I can't help you on the Eclipse debugger question since I don't
use it. It may be an artifact of the debugger or maybe DBCP's code.
You might find the DBCP project documentation helpful in answering these
questions though.

RE: Tomcat JNDI Realm + Active Directory Server
Two things that I noticed. I don't know how correct they are, but it seems to
work in my environment.
1. In my Realm definition Realm I have connectionName and connectionPassword
attributes which specify the user that can login to AD and query and
authenticate others.
2. My Realm definition is in the context of my webapp and my web.xml
configuration looks something like the following:
security-constraint^M
web-resource-collection^M
web-resource-nameLogin Screen/web-resource-name^M
url-pattern/Login.jsp/url-pattern^M
/web-resource-collection^M
^M
auth-constraint ^M
role-nameMIS Distribution/role-name^M
/auth-constraint^M
/security-constraint^M
I never use the context name in my web.xml like you have setup with
moretests.
Hope this helps.

Embedded Tomcat JNDI/JDBC Configuration Questions
Hi!
I've successfully created a project that embeds Tomcat. Excellent! I can
see the sample page and the manager app, reporting Tomcat 5.5.9. Now I'm
working on deploying a .war file programatically:
public void registerWAR(String contextPath, String absolutePath) throws
Exception {
Context context = this.embedded.createContext(contextPath,
absolutePath);
context.setReloadable(false);
this.host.addChild(context);
}
I pass in the path and the location of the .war file. When I run the
application the .war file is found and exploded to the /ROOT directory
properly. Inside of the .war file is a context.xml file. The jdbc/db
resource is defined in context.xml, inside of the .war file with the
following:
Resource name=jdbc/db auth=Container type=javax.sql.DataSource/
ResourceParams name=jdbc/db
parameter
namefactory/name
valueorg.apache.commons.dbcp.BasicDataSourceFactory/value
/parameter
parameter
namemaxActive/name
value100/value

namedriverClassName/name
valuecom.mysql.jdbc.Driver/value
/parameter
parameter
nameurl/name
valuejdbc:mysql://localhost:3306/reger?autoReconnect=true/value
/parameter
/ResourceParams
When I make a call to my application the code inside the .war file attempts
to connect to the database like this:
private static final String jndiPrePend = java:comp/env/;
private static final String jndiDB = jdbc/db;
public static Connection getConnection(){
Connection conn=null;
try{
Context ctx = new InitialContext();
if(ctx != null){
DataSource ds = (DataSource)ctx.lookup(jndiPrePend + jndiDB);
if(ds != null){
conn = ds.getConnection();
return conn;
}
}
} catch (Exception e){
e.printStackTrace();
util.errorsave(e);
}
return null;
}
But I get the following error in the console window, repeatedly, each time
my app tries to connect to the db:
javax.naming.NamingException: Cannot create resource instance
at
org.apache.naming.factory.ResourceFactory.getObjectInstance(ResourceFactory.
java:132)

at reger.db.RunSQL(db.java:124)
at reger.scheduler.MasterThread.setupThread(MasterThread.java:377)
at reger.scheduler.MasterThread.run(MasterThread.java:48)
It looks like the jndi/jdbc resource isn't configured correctly and/or isn't
available to the code from the .war file running inside of the embedded
tomcat.
Questions:
1) Is my jndiPrePend variable correct? It works for a standard deployment
on a non-embedded tomcat.
2) Is there anything special I need to do to get a jndi/jdbc resource
configured under the embedded tomcat?
3) Does the error message I'm seeing point to anything that I need to
change?
Thanks,
Joe
Tomcat, JNDI, Active Directory
Hi!
Is there anyone out there who would like to figure out what I am doing wrong
when trying to create a realm in Tomcat that is supposed to authenitcate
users over JNDI against an Active Directory server.
In my server.xml I have the following
Realm className=org.apache.catalina.realm.JNDIRealm
connectionURL=ldap://192.168.10.10:389;
alternateURL=ldap://192.168.10.10:389;
userBase=ou=Users,dc=alfa-moving,dc=se
userPattern=uid={0},ou=Users,dc=alfa-moving,dc=se
roleBase=ou=Users,dc=alfa-moving,dc=se
roleName=cn
debug=99 /
The log from tomcat says the following
004-10-14 16:04:04 JNDIRealm[Catalina]: Connecting to URL
ldap://192.168.10.10:389
2004-10-14 16:04:16 JNDIRealm[Catalina]: lookupUser(JKP_konf)
2004-10-14 16:04:16 JNDIRealm[Catalina]:

2004-10-14 16:04:16 JNDIRealm[Catalina]: validating credentials by binding
as the user
2004-10-14 16:04:16 JNDIRealm[Catalina]: binding as
uid=JKP_konf,ou=Users,dc=alfa-moving,dc=se
2004-10-14 16:04:16 JNDIRealm[Catalina]: bind attempt failed
2004-10-14 16:04:16 JNDIRealm[Catalina]: Username JKP_konf NOT successfully
authenticated
When I look in the gui of AD I se a tree like this
Active Directory Users and Computers
--+alfa-moving.se
+ Users
--+JKP_konf
So, what have I done wrong ... somehow it always seem to be me who does the
errors... .-)
Thanks in advance

Prasad, I DID. Did you miss it? Here it is again. First check you logs and see if any error messages are showing up. As a just for kicks try thing, move the username up in the configuration to before the password. Crazy thing but it caused mine to not see the password. I don't think you will get back any indications in the java trace that the password is bad but the logs will show trying to connect with the proper user but no reference to password. Note: It will not list the password in the log but will say password yes or something like that. Let us know what you find. Also give use you system info: Tomcat=5 OS=? JDK=?

Re: Known problem with tomcat, jndi datasourc - PLEASE HELP
First check you logs and see if any error messages are showing up. As a just for kicks try thing, move the username up in the configuration to before the password. Crazy thing but it caused mine to not see the password. I don't think you will get back any indications in the java trace that the password is bad but the logs will show trying to connect with the proper user but no reference to password. Note: It will not list the password in the log but will say password yes or something like that.

Tomcat JNDI
I have/had the two working together, but my only problem is this. When I blow away the webapp and its war and add a new war, my app does don't explode the war. I get a message in my tomcat log file that says: java.lang.IllegalArgumentException: Document base C:\Program Files\Apache Group\Tomcat 4.1\webapps\vp does not exist or is not a readable directory Well I know the folder is not there because it has not been exploded yet? How do I get it to explode the war before it checks or some other way? I would like to continue set my app up in a way where each time I do a load I can blow away the app folder and its war file, then add the new war file and start tomcat Anthony Smith GSP Technologies 901-263-8953 Having education and talent doesn't make you better than the world... it makes you responsible for it!
Re: Tomcat JNDI - mapping a String
I have developed a small web-based aplication. I use an ant build script to compile it and to generate a war. The application is used in several servers with different settings (it uses different databases, connects to different xml-rpc resources...) so it has to somehow read the configuration from the server environment.

Stop me, when I become wrong: 1) Enteries in GlobalNamingResources are accesible for the whole server including all deployed applications. 2) When I include Environment element into GlobalNamingResources a new Environment variable should be accessible in all applications.

Re: howto federate tomcat JNDI to another JNDI context ?
Hi mark,
I solved my JNDI federation problem and maybe you are interested to know how ?
JustToRememberMyProblem
I want to get JMS ressources from JNDI. They're stored in a FileSystem JNDI
and I need to federate it to Tomcat JNDI.
/JustToRememberMyProblem
I added a custom factory to tomcat (in commons/classes):
import java.util.Enumeration;
import java.util.Hashtable;
import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.Name;
import javax.naming.NameClassPair;
import javax.naming.NamingEnumeration;
import javax.naming.NamingException;
import javax.naming.RefAddr;
import javax.naming.Reference;
import javax.naming.spi.ObjectFactory;
public class JndiFederationFactory implements ObjectFactory {
public Object getObjectInstance(
Object obj,
Name name,
Context nameCtx,
Hashtable environment)
throws NamingException {
Reference ref = (Reference) obj;
Enumeration addrs = ref.getAll();
String lookup = null;
Properties props = new Properties();
while (addrs.hasMoreElements()) {
RefAddr addr = (RefAddr) addrs.nextElement();
String type = addr.getType();
String value = (String) addr.getContent();
if (type.equals(lookup)) {
lookup = value;
} else {
props.put(type, value);
}
}
InitialContext ctx = new InitialContext(props);
if (lookup == null) {
throw new NamingException(la propriété lookup doit être définie);
}
return ctx.lookup(lookup);
}
}
I added IBM MQSeries/JMS client classes to commons/lib
I added this conf in server.xml :
Resource name=jms/QueueConnexionFactory auth=Container
type=javax.jms.QueueConnexionFactory/
ResourceParams name=jms/QueueConnexionFactory
parameter
namefactory/name
valuecom.cgey.JndiFederationFactory/value
/parameter
parameter
namelookup/name
valueurlQmgrLocal/value
/parameter

namejava.naming.factory.initial/name
valuecom.sun.jndi.fscontext.RefFSContextFactory/value

parameter
namejava.naming.security.authentication/name
valuenone/value
/parameter
parameter
namejava.naming.provider.url/name
valuefile:///c:/MQSeries/jndi/value
/parameter
/ResourceParams
Using this, I can lookup in local JNDI from my webapp for jms/QueueConnexionFactory
and get the MQSeries
QueueConnexionFactory defined in a FileSystem JNDI Context. This is a pseudo JNDI
Federation, but it works fine.

Re: howto federate tomcat JNDI to another JNDI context ?
Hello Nico,
Yes I've been attempting to do the same thing with suns LDAP Context.
Unfortunately (even for myself as an Apache Jakarta Developer, neither
the tomcat user or developer lists have gotten any responses to my emails).
I've done several attempts to start a discussion on this, maybe you will
find my mistake path helpful:
Tomcat User:
http://www.mail-archive.com/[EMAIL PROTECTED]/msg114976.html
http://www.mail-archive.com/[EMAIL PROTECTED]/msg114923.html
Tomcat Dev:
http://www.mail-archive.com/[EMAIL PROTECTED]/msg51159.html
The nearest I can figure out is that you may have to write your own
object factory to instantiate the objects even if one is provided by
Sun. Otherwise your really going to be troubled with what ResourceParams
are actually getting configured into the federated Context. I actually
had to decompile the ldap factory com.sun.jndi.ldap.LdapCtxFactory to
identify the fact that it sets none of these
ReferenceAddrs/ResourceParams properly into the environment of the new
context.
If your studying all the JNDI Tutorial stuff and documentation its
important to note that whats really getting set when you create Resource
Params like this are Reference/ReferenceAddrs in JNDI.
Resource type=com.sun.jndi.ldap.LdapCtxFactory auth=Container
name=ldap/
ResourceParams name=ldap
parameter
namejava.naming.factory.initial/name
valuecom.sun.jndi.ldap.LdapCtxFactory/value
/parameter
/ResourceParams
equates to:
Hashtable env = new Hashtable();
Reference ref = (Reference) obj;
Enumeration addrs = ref.getAll();
while (addrs.hasMoreElements()) {
RefAddr addr = (RefAddr) addrs.nextElement();
if(!addr.getType().equals(factory))
env.put(addr.getType(), addr.getContent().toString());
}
return this.getInitialContext(env);
in the factory (which all kinda sucks for anyone trying to use an
existing factory that may not actually do this consistently.
Unfortunately the JNDI tutorial is rather weak in substance when it
comes to actually federating two namespaces.

Referencing Tomcat JNDI datasource
Hello, I am using Tomcat 4.1.18 and have setup a JNDI datasource for database connection pooling. I would like to reference this datasource from another application that is not running under Tomcat. In searching the mailing list archive and other forums I found dated information that indicated that this was not possible that I would have to use another database connection pooling utility such as DbConnectionBroker from Javaexchange.com. Is this still the case with the latest versions of Tomcat? Has anyone used DbConnectionBroker to provide database connection pooling with Tomcat and in a stand alone application? Any suggestions on other ways to use a database connection pool with Tomcat and from a stand alone application?

help needed regarding tomcat jndi database connection pooling
Hi All, I have integrated tomcat 4.0.4 with apach 1.3.x. I have configured one of my tomcat contexts for database connection pooling and written a small jsp program to test the connection pooling by making use of jndi lookup.. The problem is when i access the context through port 8080 then I am able to make the jndi lookup and connection pooling is properly working. But when i try to call the same context through apache's port 80 I am unable to connect to the database. I am making use of mysql database..

RES: Is there a problem with tomcat JNDI resources (I don't think so)

ENC: Is there a problem with tomcat JNDI resources (I don't think so)
I got my answer in this thread: Make sure you have the ResouceLink Tag inside each context that needs to use this datasource. Also, in using Global Resources, there is no need for a resource-ref tag in your web.xml config file anymore. iran -Mensagem original- De: Iran Marcius [mailto:[EMAIL PROTECTED]] Enviada em: sexta-feira, 20 de dezembro de 2002 13:52 Para: 'Tomcat Users List' Assunto: RES: Is there a problem with tomcat JNDI resources (I don't think so) If I'm not mistaken, I read somewhere that using GlobalNamingResource with ResourceLink (inside Context) make unnecessary to put resource-ref in web.xml.

could not cast dbcp objects created using tomcat JNDI
I retrieved an object of DataSource using Tomcat's JNDI simulation. It is an instance of BasicDataSource. I tried to cast it to BasicDataSource and got a ClassCastException. Context ctx = new InitialContext() ; Context envCtx = (Context) ctx.lookup(java:comp/env) ; DataSource ds = (DataSource) envCtx.lookup(jdbc/myoracle) ; BasicDataSource basic = (BasicDataSource) ds ; Actually, I cannot cast any DBCP objects, e.g. PoolableConnection.
tomcat + jndi
Hi, I posted earlier but unfortunately got no response. I´ve also had a look at various mailing lists but found no answer. If I have tomcat installed on a seperate box and have some classes which I want to reach via JNDI, how would my tomcat specific jndi.properties look like? Any help would be _really_ appreciated.

Re: Tomcat + JNDI
Have you defined the resource itself in server.xml? You'll need to set up
the appropriate Resource and ResourceParams elements there in order to
define how Tomcat is actually supposed to create the object factory for
this resource. See the jndi-resources-howto.html for more information on
creating object factories for your own beans.

Re: Tomcat + JNDI
thanks Craig,
that´s what I thought I read I was hoping that maybe there is an easier
way then wrinting my own factory to retreive objects via JNDI. What I need
is a factory which can return any JDO objects. I noticed in the particular
example provided by tomcat that you have to initialize the object in the
factory. So that would mean that every time I create a new JDO object, I
have to add it to the factory. Or have I missed something here? Any
suggestions?
Thanks very much,
Michael

tomcat / jndi
Hi all, i have some questions on jndi of tomcat : 1) if i put a class in tomcat jndi, and will the class constructor be exectued ? if it will, when will it be ? Once tomcat start up ? or first client get resources ? or will not execute constructor at all ? Since I go to tomcat doc and find that most of the classes don't have constructor. So I am not clear in this. 2) If multiple client request for the same resource, is it only one copy of the class will be shared between the clients?

Passing a Tomcat JNDI context to a jCrontab task
Apologies if this is too off topic. I am looking at using the jCrontab servlet to do some task scheduling most of which has to do with mailing reports generated from data in the application's database. Although I could do this using the Class.forName() paradigm I would like to use the same Datasource pool I have already running. In order to obtain a reference though, I need the InitialContext. There seems to be three ways to approach this problem but I am not sure which are possible much less which may be best. The first seems to be to have jCrontab make a call to a class which somehow obtains the InitialContext reference. My problem is knowing how to access the Tomcat Context from an application which does not have a implied reference to the Tomcat context such as a Bean or Servlet would have. The second seems to be to pass a reference of the Context to the application but I am not sure it is possible for jCrontab to do that? The third would be for jCrontab to somehow invoke a servlet or Bean within the Tomcat context but after studying the Tests suite and reading through the documentation I am at a loss of how to invoke a class which does not have main method. If anyone has a suggestion or even where I might find one I'd appreciate the hint.

tomcat, JNDI naming, and OracleDataSource
I don't know if my original message made it to the list yet. I received the
following error when I tried to send a question to tomcat-user list:
- The following addresses had permanent fatal errors -
[EMAIL PROTECTED]
(reason: 550 User unknown)
I'm not sure why it redirected to namezero.com. Hope this one makes it!
I'm trying to get a JNDI example of my own working - the one in the example
context works fine. I originally wrote because I couldn't even get an
IntialContext instantiation to work. I solved that by making sure the
naming.jar file was in my application-context classpath. Actually, I hope the

Anyway, here's the problem. In my code, I instantiate an InitialContext
and then do a lookup for a DataSource (connection factory). The lookup
fails with the following exception:

I'm at home right now so I don't have the code in fron of me but it is
basically as follows (with the naming exceptions caught and turned into
ServletExceptions):
import javax.naming.*;
import javax.sql.*;
public void init( ServletConfig config ) throws ServletException
{
super.init(config);
InitialContext ic = new InitialContext();
DataSource ds =
(DataSource)ic.lookup(java:comp/env/jdbc/NamingDataSource);
}
and here is my web.xml file:

So the exception says:

but isn't it enough to declare/define it in my web.xml file.
I'm going to look through the ejb specification tomorrow in case it sheds
any light (since the servlet spec says naming and resource references are

As an aside, what I'm actually trying to do is get an

I thought I'd start with a simpler case. I'm also waiting to see if

When you see messages like this, it means that the list tried to send email
to that person (in your case [EMAIL PROTECTED]) and that email
address was no good. This does NOT mean that the rest of the list didn't
get your email. There is no need to post a second time. I just delete all
the bounce/redirect messages that I get after sending to this list.

I'm at home right now so I don't have the code in fron of me but it is
basically as follows (with the naming exceptions caught and turned into
ServletExceptions):
import javax.naming.*;
import javax.sql.*;
public void init( ServletConfig config ) throws ServletException
{
super.init(config);
InitialContext ic = new InitialContext();
DataSource ds =
(DataSource)ic.lookup(java:comp/env/jdbc/NamingDataSource);
}
and here is my web.xml file:
?xml version=1.0 encoding=ISO-8859-1?

Tomcat JNDI
I am trying to tie Tomcat with JNDI to use J2EE pattern to obtain resources:
Context context = new InitialContext();
dataSource = (DataSource)context.lookup("java:comp/env/jdbc/myDataSource");
(I know Tomcat team is planning to have it for Tomcat 4 eventually)
I have my own little in memory JNDI implementation with support for
java:comp URLs
and it works fine but provides one global JNDI for all contexts defined in
server.xml while it should be context specific. Basically the problem is how
to make InitialContext() tomcat context aware (to be precise to make my
java:comp namespace to start from different roots depending on where
InitialContext was created).
If AdaptiveClassLoader had some context info in it I could get it from there
while creating InitialContext.
Any ideas are greatly appreciated

Interesting timing ... the code to do this (in Tomcat 4) was added just in the
last couple of days (after milestone 4).

If I recall correctly, it's actually sort of tricky to get this right. You
might want to check the source for the Tomcat 4 implementation for ideas -- I
believe it depends on the servlet container calling
Thread.setContextClassLoader() once you know which webapp you're running in.
This only works in a Java2 environment, though.
Any ideas are greatly appreciated
