Re: Multiple war files for a single webapp or context
Would the nested context approach allow access to session data from one war file to the other?

If any of the files change (either the jsp, css, js or java files) i have to always rebuild the whole war file. This means i deploy every single file on every release. I am wondering if there is a way to deploy specific areas of the application. I am particularly interested if it is possible to separate the application into multiple war files. i.e. myapp.war, articles.war and forum.war. I would like to still access the application via the same context i.e. http://0.0.0.0/myapp even though multiple war files are used. Using this approach, i will be able to deliver just the module that was affected by the change. Is this at all possible? I dont mind having to restart the container after each war file is deployed. You are not saying what Tomcat version you are using. It is possible to create wars for nested context. E.g. to separate scripts into myapp#js.war - the root of this web application will be /myapp/js/ Note that all web applications are independent of each other, so you need to have separate web.xml for each of them, and you cannot access to code that belongs to another web application.

Ok, so how does your client provide a username and password to the server's

locally on the same machine or remotely from a different machine?
I believe that in this context, remote just means via a TCP/IP
connection.
It does not matter if your client is on the same host or not. If it
accesses the server via TCP/IP, then it counts as remote.
There is another way to connect, limited to local processes running on the
same host, but I forget how it is called or how it works.
You can see the distinction pretty clearly by using the jconsole
application, which is included in the JDK.
Note : for the remote kind of access, there is another (second) TCP
connection used, separate from the port which you indicate with the
jmxremote.port parameter.
If you are on the same host, it does not matter, but if you really need to
connect from another host through a firewall or so, it may.

you let this JVM know which remote user-id's can connect, and what password

Now, from the client side, when you connect, you have to provide such a
valid user-id and password, to login to the server.
If you try the jconsole utility as a client, you will see this on the
connection box.
I have no idea how you supply these credentials programmatically from
/your/ client, but that is what you have to find out.

Given that Jconsole can connect to the Tomcat JMX without any user

Tomcat monitoring using JMX
Hi, I am using JMX to connect to a Tomcat instance and looking at attributes for a jdbc datasource as shown below. MBeanServerConnection conn = jmxc.getMBeanServerConnection(); ObjectName on = new ObjectName(Catalina:type=DataSource,path=/appdb,host=localhost,class=javax.sql.DataSource,name=\jdbc/appdb\); mbsc.getAttribute(on, numIdle) Is there an Mbean provided by Tomcat that can provide me the following information - Whether Tomcat is running - Whether a specific web app running under a specific context is runnin - The health of the environment in general (tomcat, OS etc) - Whether a JNDI datasource is available and if possible how many active database connections there are and how many free. I have been google'ing around but the majority of the examples talk about writing your own Mbean and including it as part of the application. I am trying to write an external client utility that will monitor the application away from Tomcat. Thanks
Accessing context information remotely - Context.getAvailable() etc.
I was looking at the code for the Tomcat Manager application to try and find
out how it is determining whether a webapp/context is running and how many
sesions are active. Looking at the code i think it uses these two methods
Context.getAvailalbe() //check if available
Context.getManager().findSessions().length // Number of sessions.
Here is the relevant function
protected void list(PrintWriter writer) {
if (debug = 1)
log(list: Listing contexts for virtual host ' +
host.getName() + ');
writer.println(sm.getString(managerServlet.listed,
host.getName()));
Container[] contexts = host.findChildren();
for (int i = 0; i contexts.length; i++) {
Context context = (Context) contexts[i];
String displayPath = context.getPath();
if( displayPath.equals() )
displayPath = /;
if (context != null ) {
if (context.getAvailable()) {
writer.println(sm.getString(managerServlet.listitem,
displayPath,
running,
+
context.getManager().findSessions().length,
context.getDocBase()));
} else {
writer.println(sm.getString(managerServlet.listitem,
displayPath,
stopped,
0,
context.getDocBase()));
}
}
}
}
I was looking at the above for the above information as i am working on a
client tool that tries to find out this exact information. The tool i am
using connects to Tomcat via JMX but i am not sure if i can get the same
information via JMX. Can i access the Context class? or is there any other

Re: Accessing context information remotely - Context.getAvailable() etc.
Hi,
Thanks for your response. I am aware of the activeSessions attribute under
Catalina:type=Manager,path=/testapp,host=localhost. I am actually doing
this programmatically and would like to know of an Mbean that would tell me
if the application is available. The activeSessions attribute can sometimes
report 0 even when the application is available so it is not reliable.

Connect to a Tomcat instance using JConsole and look for the 'Manager'

There's an attribute 'activeSessions'.

Re: Accessing context information remotely - Context.getAvailable() etc.
Well it is a little complicated but the main reasons are - The majority of the tools i have looked at require that the tool run inside Tomcat which is where my application will also be running. This is a problem because if Tomcat itself is not available then i cant monitor anything - It will be quicker for me to produce something quicker myself than it will be to convince my boss to authorise an open source tool for a project that is not supposed to be accessed by external users.

setenv.sh in an individual tomcat catalina base
Hi guys, At the moment i have several catalina bases configured with the following directories, conf logs server webapps work The bin, lib and common directories are all still in $CATALINA_HOME. I now need to add a setenv.sh file in the bin directory but i dont want it to be used by all the catalina bases. I only want 2 out of the 4 catalina bases to use the setenv.sh file. To do this i am thinking of adding a bin directory on the catalina_base/bin that i want to pick up the setenv.sh file. The bin directory will only contain the setenv.sh file and nothing else. Everything else will still be in $CATALINA_HOME/bin/ (ie. startup.sh catalina.sh shutdown.sh etc). This means that some catalina bases will have /bin directories and some wont. Are there any side effects to doing this? Can tomcat use both $CATALINA_BASE/bin/ and $CATALINA_HOME/bin during startup?
Re: setenv.sh in an individual tomcat catalina base

It is possible to run multiple instances of Tomcat. When you run it within Netbeans, the instance you are running is not the instance in your $CATALINA_HOME.

Multiple war files for the same application context.
Hi guys, Is it possible to deploy multiple war files for the same application? for example if i have an application that is accessed via http:/// www.test.com/myapp, i would usually have a single war file called myapp.war and deploy everthing in that one file. is it possible to deploy myapp1ArticleManager.war, myapp1Forum.war etc and have them all be as part of the one myapp application? Any links or tutorials on how to do this would be very helpfull. And what is the term used for this kind of deployment? Thanks
Re: Multiple war files for the same application context.
Hi Hassan, I was recently looking at a CMS portal and found that the portal allowed plugins/application to be deployed as war files.

I see what you mean Hassan.

Sure, the whole point of a portal is to integrate non-related apps and data sources. So you access the portal context which basically proxies in the output of those plugins.

Re: Regarding 1 Webserver Multiple Web App project
What is wrong with two domains? i.e. www.domain1.com points to webapp1 www.domain2.com points to webapp2 Both domains need to be pointing at the same IP address i.e. the IP address of where the webapps are hosted. Then just use virtual hosting using Apache or Tomcat to redirect. If you are using tomcat on its own then i think you will need to configure virtual hosting.

Read all the responses; you do *not* need the shutdown port in Windows.

You should have the links target your own script that determines whether or not Tomcat is running and starts it only when needed. Next import point we are not shutdown server because user don’t want to see the tomcat console so we are just leaving server when user will restart machine then will system will remove instance from memory. That would be a guaranteed reason for me *not* to buy your application. My question is there any way to set up time to stop the server like after two or 3 hours? Configure a lifecycle listener for each webapp; if there's no activity for any of them over the desired time period, send the shutdown signal. It's probably easiest for you to leave the shutdown port configured, but use a different password. Since the user has complete control of the machine, the user can kill the Tomcat process any time he or she chooses, so the presence of the shutdown port listener is not really a concern. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: Tomcat common/lib
The problem i had with the Oracle specific functions is that they only work
if the connection object is of a oracle.jdbc.driver.OracleConnection type.
I am using Oracle Specific Types which i found are just a pain to use with
Java because they cause lots of issues one of them being interfacing with
Java programs.
This is an issue because when i get the connection object from a DataSource
object that I lookup via JNDI, the connection is not a real OracleConnection
object, but an object that wraps the real OracleConnection. The object that
you get is an instance of class org.apache.commons.dbcp.BasicDataSource.
When you call getConnection on this object, you get an instance of class
org.apache.commons.dbcp.PoolingDataSource$PoolGuardConnectionWrapper (which
obviously implements java.sql.Connection, and wraps the OracleConnection
object).
Because of this i couldnt really use the connection object provided via
JNDI. I did initially just bypass jndi and created a new conneciton via
java.sql.Connection. This worked fine for a couple of months but then i
decided to change it as it became a pain to have to maintain the database
properties in two places. I.e. on the jndi properties and the properties
file for the direct connection.
The other problem i had is that when i had two connection types, i was
getting lots of problems with the way the driver was being loaded. I think
this was because Tomcat was already loading the jdbc driver via common/lib
and i had the driver in WEB-INF/lib it was not happy about it. Anyway now i
only have the driver in common/lib and use just jndi using the underlying
connection delegate.
I had a look around and found that i could get the underlying connection
from the
org.apache.commons.dbcp.PoolingDataSource$PoolGuardConnectionWrapper object
which is what i did. Now i dont have to maintain the database properties in
two places.
How about java.sql.Array instead? I guess it depends on what you're
doing with it...
Does this map to an Oracle Type?
I will play around with it to try some of your suggestions and see what
happens. Thanks for the help.
Thanks

Aah, if you need to get the underlying connection, then you'll need to
cast to Tomcat's implementation. Note that you can use reflection to
avoid static typecasting and maybe free yourself from needing to have
the Tomcat classes around for compilation.
Why do you need to access the underlying connection? Probably do to some
Oracle-specific stuff:

[javac] symbol : class ArrayDescriptor
[javac] location: class data.accessors.ConsignmentDAO
[javac] ArrayDescriptor rectabDescriptor
=
ArrayDescriptor.createDescriptor(LIST_TYPE,underlyingConnection);
I believe you can use native Java arrays for some if this stuff, as long
as you have properly configured your driver. You may have to toy with
the type mapper on the Connection object, though.
I know that dealing with SQL ARRAY types is usually pretty hacky. Have
you tried simple things like just doing:
int[] ints = ...;
callableStatement.setObject(n, ints);
... and see what happens?

Multiple tomcat instances
Hi, I have set up multiple Tomcat instances using the multiple CATALINA_BASE approach. Everything works fine but i have two issues that i need clarification on. I am currently using Tomcat 5.5 1. When i have created the new folders that $CATALINA_BASE will point to, which files do i need to copy to the 'conf' folder. I have tested this and found that it works fine if i just move the web.xml and server.xml file. My question is do i need to copy the other files as well (i.e. catalina.policy, catalina.properties, context.xml, logging.properties, server-minimal.xml). What is the best thing to do, should i copy all the files from $TOMCAT_HOME/conf to CATALINA_BASE/conf?. I guess it would be usefull if i can find out exactly what each of these files are for. is there a file that i definately need to copy other than the web.xml and server.xml? 2. I had a second question but my mind just went completely blind! Ill update the email when i remember it. Madness i know :)

Deploying and building a war file
Hi all, I've got a query on the way web applications are deployed. I have an application that has several jsp files and serlvets that are in WEB-INF/classes. When i deploy the application all i do is do a checkout on CVS, make the changes, rebuild the war using ANT and redeploy manually. This works fine but now i am having some doubts on this approach. Basicaly if i even change one file i have to rebuild the war file meaning i have to recompile everything. I think this is unecessary. i would like to be able to just recompile the one file and redeploy the one file without having to rebuild the whole war file. 1. How do you deploy your application?

Re: Deploying and building a war file
Hi Ken, I do use eclipse but only for development. I cant really deploy from eclipse for several reasons. One of them being that the deployment server is a different machine from where i do the development. Thanks On Mon, Nov 9, 2009 at 7:12 PM, Ken Bowen kbo...@als.com wrote: If you use Eclipse (www.eclipse.org/ free; runs on Wins/Mac/Linux) with the web plugins, it records your deploy target, and allows you to deploy with either a war file, or in exploded form. In the latter case, you can usually leave your web server running, make a code change, save the file, and it is automatically re-compiled re-deployed to the running server. At worst, you only need to hit a refresh button.

Can a JNDI resource be in a webapp's lib folder
I am trying to set up a JNDI resource of an Oracle database connection. I have set the connection details in my application's context file in $CATALINA_BASE/webapps/myapp/META-INF/context.xml I put the jdbc driver in $CATALINA_BASE/common/lib and everything works fine. The problem is i dont want to put the jdbc driver in that directory. I would like to put it in $CATALINA_BASE/webapps/myapp/WEB-INF/lib I have read about this a bit and i think that all JNDI resources must be in $CATALINA_HOME/common/lib which explains why If i put the driver in the application's lib folder it cant access it because the common class loader wouldnt konw of the libraries in the applicatoins lib folders.. The tomcat installation only runs this one application. I would like to be able to move the application's war file (which will include all libraries in the WEB-INF/lib folder) around to other tomcat instances if i need to without having to worry about moving libraries as well. Its a bit weird that i configure the JNDI resource in the application's context file but the library that the context file is refering to is to be kept outside of the application. is there a way i can use the JNDI resource but have the jdbc driver in the application's WEB-INF/lib directory? Thanks in advance.

jar file loading priority
Hi all, Could someone please clarify this for me as i have always wondered about it but couldnt find any usefull information. Given the following directories $JAVA_HOME/jdk/lib/ $JAVA_HOME/jdk/jre/lib/ $JAVA_HOME/jdk/jre/lib/ext $TOMCAT_HOME/common/lib $CATALINA_BASE/common/lib $CATALINA_BASE/myapp/WEB-INF/lib I know that even though it is not recommended i can practically place my jar files in any of the above directories and my application which is in $CATALINA_BASE/myapp should pick it up. The reason i am curios about this is i had the activation.jar in $CATALINA_BASE/myapp/WEB-INF/lib and recently found out that JDK1.6 also comes with activation.jar which it places in /usr/share/lib under Solaris. Now what i am wondering is what is the order in which the jar files will be loaded? For example, what will happen if i have ojdbc14.jar in all the above directories? Which one will be picked up first? And also is there a way to find out if there are duplicate jar files which one was used? Please note that i do know that it is not recommended to place jar files in non app lib folders. I just want to know the order in which the jar files will be loaded to satisfy my curiosity :). Thanks

I know if I want to initialize things on startup I include the load-on-startup1/load-on-startup in the web.xml for the app; which will load the servlet and execute what's in the init method.

Otherwise, I don't see how it will create those connections and load the pool on startup.

Re: How to install an updated third party SSL certificate for B2B transactions
On 9/8/09, Peter Crowther peter.crowt...@melandra.com wrote: 2009/9/8 David Uctaa duc...@gmail.com I have inherited a Tomcat 5.5 installation running on Windows XP. There are processes on this box which do server-to-server connections with a third party via HTTPS over SSL. We have installed the third party's SSL certificate on our server, and they have done likewise with ours. We use their certificate for recognizing messages that they have signed and encrypted, etc. OK. So the first step is to work out what piece of code uses their certificate. It's unlikely to be Tomcat, which probably uses your certificate to identify itself to them - but it's possible. It's more likely to be one or more B2B web applications (webapps) running inside Tomcat, which probably check returns from them to make sure the correct cert has been seen from their server. They have now updated their certificate and sent it to us. But I do not know how or where to update this on our system. Do I need to do something with the keystore? Are there resources online which will give me the how-tos on this? I've googled around and only managed to confuse myself further. I think it'll stay confusing until you answer the above question. You'll have to find / create / mind-read the documentation about which part of the system needs to know about which certificates. I suspect finding that out, or simply finding the architecture diagram that shows what apps are hosted in what containers and how they communicate, would be very useful to you! Once you've got more information, you can then ask far more targeted questions. They might be of the Tomcat users if that's relevant, or they might be of some other group that knows about the technology in your B2B webapps. Hope that helps.

Re: 100% usage and hanging on startup of Spring/Hibernate app in Tomcat 5.5 on Ubuntu 7
I noticed that you mention that you are using the community version of the Java runtime environment which i think is what you get when you do an apt-get. I have never honestly been able to use this version of the JVM successfully. I had a similar problem recently where i was running an application (That uses Hibernate) using this version of the JDK and was always getting memory exceptions. What i did was to download sun's version of the JDK and that seem to have solved the problem. Did you try to use the SUN's version of the JDK from the SUN website? It might be usefull to try the SUN's version just to rule out that the JDK version/release is not the problem.

dbcp error with java.lang.ClassCastException: org.apache.tomcat.dbcp.dbcp.PoolingDataSource
Hi All,
I am using jdbc to connect to an oracle database but having a bit of a
problem. Here is some details
Jdbc driver - Type 4
App server - Tomcat 5.5
Oracle Version - 10g
I have placed the jdbc driver on both the following directories
[code]
$TOMCAT_HOME/common/lib/
$APPLICATION_ROOT_DIR/WEB-INF/lib/
[/code]
Here is the stack trace of the error i am getting.

Re: javax.naming.NamingException: Cannot create resource instance
Hi,
The tomcat version on my Desktop is 5.5.27 and the Tomcat version on the
Unix environment is 5.5.23. Could the above minor version difference cause
it?
One thing i have noticed is that if i take the /META-INF/Context.xml file
and copy it into $CATALINA_HOME/conf/Catalina/localhost/testapp.xml it does
work.
i.e. why does it require the context file in that directory and why does it
have to be renamed to my applications context. On the Windows environment i
dont have to rename and copy the context file to
$CATALINA_HOME/conf/Catalina/localhost
Thanks

Re: javax.naming.NamingException: Cannot create resource instance
A bit more info which i think might be relevant.
When i run it on my desktop i ran it directly from within Netbeans but when
i run it on the Unix server i export the project as a war file (within
netbeans) and copy it into the webapps directory on the Unix environment.
Is it possible that netbeans is including some libraries that are not
available on the Unix environment when i run it on the desktop?

Yes it looks like that fact it is named with uppercase C was the problem. I
renamed it to context.xml and it finally worked.
Thank you all for your help.

The Windows file system is one of the few (the only one I can think of)
that's not case sensitive. Unix, linux, bsd, macos, etc. , ... are all case
sensitive. You should change the file name 'Context.xml' to 'context.xml'
and check to be sure it stays that way as you build your .war file. After
that you won't need to have testapp.xml in conf/Catalina/localhost. Also
you might want to check all the places in your webapp that references a file
and be sure the names match in case to what's on disk.

I check all the libraries and everything under common/lib is the same for both environments. Thanks Edited by: ziggy on Oct 1, 2008 3:48 PM Edited by: ziggy on Oct 1, 2008 3:50 PM
Re: javax.naming.NamingException: Cannot create resource instance

environment.
Thanks.

Hi,
I am trying to connect to an oracle database but cant seem to get the jdbc
connection to work. I am developing the application on a Windows desktop and
transferring it onto a Unix box.
When i test it on the Windows environmnet it does manage to connect but if
i test it on unix then i get an error. My gut feeling is that the
installation on the unix environment is missing a library but i cant figure
out what it is.
Here is how i am trying to get the jndi connection.
[code]
String fullname;
if (jndiPrefix != null jndiPrefix.length() 0)
fullname = jndiPrefix + datasource;
else
fullname = datasource;
// JNDI
Context ctx = null;
DataSource ds = null;
Connection conn = null;
try
{
ctx = new InitialContext();
Context envContext = (Context)ctx.lookup(java:/comp/env);
if (ctx != null)
{
ds = (DataSource)envContext.lookup(fullname);
if (ds != null)
{
conn = ds.getConnection();
}
}
}

And here is the Configuration.

Re: jdbc driver fails with tomcat
Hi, When i debug the code, it doesnt get to the point where i am initialising the OracleCallableStatement object. It failed just after the initialisation of the ArrayDescriptor object.
