Re: Help: Connecting Tomcat to CA-IDMS using JDBC Type 4 Drivers (JNDI / IDMSDataSource)
Filip, here is my configuration so far:
I have created a test application under the tomcat webapps folder with the
following structure:
IDMSTest/
IDMSTest/WEB-INF/
IDMSTest/WEB-INF/classes/
IDMSTest/WEB-INF/lib/
IDMSTest/WEB-INF/web.xml
IDMSTest/WEB-INF/test.jsp
Here is my IDMSTest/WEB-INF/web.xml file:
?xml version=1.0 encoding=UTF-8?
web-app xmlns=http://java.sun.com/xml/ns/j2ee;
xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance;

descriptionDB Connection/description
res-ref-namejdbc/TestIDMS/res-ref-name
res-typejavax.sql.DataSource/res-type
res-authContainer/res-auth
/resource-ref
/web-app
I also added the following to tomcat/conf/server.xml:
!-- Tomcat JDBC to IDMS Test Context --
Context path=/IDMSTest docBase=IDMSTest reloadable=true
crossContext=true
Resource name=jdbc/TestIDMS auth=Container
type=javax.sql.DataSource

username=MY_USER password=MY_PASS
driverClassName=ca.idms.jdbc.IdmsJdbcDriver
url=jdbc:idms://MY.IP.ADDRESS:MY.PORT/MY_DATABASE /
/Context
Then I have a test.jsp in the IDMSTest/ folder with the following code:
%@ taglib uri=http://java.sun.com/jsp/jstl/sql; prefix=sql %
%@ taglib uri=http://java.sun.com/jsp/jstl/core; prefix=c %
sql:query var=rs dataSource=jdbc/testIDMS
select text_message from messages
/sql:query
html
head
titleIDMS DB Test/title
/head
body
h2Results/h2
c:forEach var=i items=${rs.rows}
Text Message: c:out value=${i.text_message}/br
/c:forEach
/body
/html
However, I can't actually test anything yet, as the IDMS is not setup to
listen to JDBC requests. I just wanted to be clear that my configuration and
syntax on the Linux / Tomcat side are correct for when I do come to test a
connection. The SQL query and query handling code in the JSP file would
differ depending upon the database structure, obviously.but does
everything look like its setup OK? Where would the
javax.naming.spi.ObjectFactory implementation come into it?
There are some remaining issues I have about how to setup and use the
caidms.properties file and the caidms.cfg file. I've uploaded the 2 files as
they contain quite a lot of code:
http://www.nabble.com/file/p21451684/caidms.cfg caidms.cfg
http://www.nabble.com/file/p21451684/caidms.properties caidms.properties

If your JDBC driver has a DataSource, then check to see if it has a

specify in the factory=some.impl.DataSourceFactory attribute, for

Some drivers don't have factories, and then you simply use Tomcat's own
factory by omitting the factory attribute.
In this case, Tomcat will provide the DataSource that is a wrapper
around your driver.

Hi there,
I have a rather interesting / complex problem..creating a connection
to
CA-IDMS from Tomcat using JDBC type 4 drivers (CA provide the type 4
driver).
We have a zSeries 9 IBM mainframe running CA-IDMS r16.1, and I need to
connect to the IDMS from Tomcat (running on Linux) using the JDBC Type 4
drivers provided by CA.
At this stage I am struggling with the actual setup and configuration of
Tomcat’s server.xml and web.xml files. These are the files where the JDBC
configuration is set (I think). I have to setup the CA-IDMS part of the
configuration, but that is a different problem. Basically there is a
TCP/IP
listener on the IDMS, waiting for incoming connections from the JDBC type
4
driver.
I set up a Tomcat to MySQL connection using MySQL Connector / J, which is
a
similar kind of process to what I am trying to achieve with IDMS. MySQL
connector / J came with a jar file which is placed in Tomcat’s lib
folder,
and then the JDBC setup for the web application is created in Tomcat's
server.xml and web.xml files. You can then connect to the MySQL database
using JSP and the configured JDBC driver / connection. The CA-IDMS Server
comes with an idmsjdbc.jar file, which I think is the JDBC typr 4 driver.
I
think it needs to be placed in the Tomcat /lib folder, but I don’t know
how
to set up the configuration.
There is a JDBC DriverManager which allows JDBC drivers to connect to
CA-IDMS. The DriverManager recognises the following syntax:
jdbc:idms://hostname:port/database
This allows the JDBC driver running within Tomcat to connect to the IDMS
which is running on the IDM mainframe. CA IDMS r16 supports direct
connections from the Type 4 JDBC driver to the Central Version on IDMS.
hostname is the DNS name or IP address of the machine where the CV is
running, and port is

You could instead tell us exactly which 6.x you are using and on which OS. There's a couple of things that may be confusing the config below, which have some simple corrections. I usually place login.jsp and error.jsp in WEB-INF/login/, where they are protected from unwanted attention by default - this avoids the need to protect them with a security-contstraint. You are also protecting index.jsp - which will force a login when the apps homepage is accessed, is this what you intended? Are you logging out programmatically, using the servlet method request.getSession().invalidate(), or are you just clearing cookies? Your primary problem sounds like you have placed some CSS or script files somewhere in a protected directory and the browser is requesting them without providing the correct authentication credentials. Tomcat returns the *first* file you requested inside the secured area after authentication is completed. So for some reason your browser is requesting a script or CSS file before the JSP page. Are the script and CSS files in an unprotected directory? p Disclaimer and confidentiality note Everything in this e-mail and any attachments relates to the official business of Sender.

There's no simple answer. Depending on your webapp you can change response content type directly in JSP files.

JESESSIONID
Hi, was wondering if someone could clear this up for me. We have mod_jk in apache loadbalancing our JBOSS cluster with session affinity. We've noticed that once the JESSIONID has been created with the call to req.getSession() and the jvmroute encoded by the tomcat worker, that if the JBOSS instance that originally created the HttpSession is taken off line the next JBOSS instance that receives the request doesn't rewrite the cookie with the new JESSIONID for that app server? Is that the correct behaviour? I was under the impression that a call to req.getSession() would either return that users session or create a new one for that server and hence write that value to the cookie, providing the browser supports cookies? Should the value of the original JSESSIONID be overwritten with the new value? We're not using any Tomcat clustering or marking the app distributable in web.xml.

webapp in tomcat context cannot access a python proxy residing in apache
Hello all, not sure if this should be asked here or in the apache list so I will try here first. I have an application running completely inside of tomcat 6...lets call it webappTomcat which runs on port 8084. A coworker developed an application that runs mainly on apache(html and javascript) although he makes ajax requests to servlets. Lets call it webappApache. When he makes his ajax requests he does so through a pseudo proxy(to allow cross domain) that is written in python. This proxy resides in apache on port 80. We need to merge both applications. I want to merge webappApache *into*webappTomcat. Basically bring all of the html and javascript code from webappApache into webappTomcat and retain the use of the proxy on Apache for cross domain calls. When I do this, the calls to the apache python proxy fail. It seem like there is no *path* to the proxy from tomcat. example: http://localhost:8084/webappTomcat/index.jsp makes an ajax call through the proxy to http://localhost:8084/anotherTomcatWebApp/Servlet http://localhost:8084/webappTomcat/index.jsp --- http://localhost/webappApache/pythonProxy.py --- http://localhost:8084/anotherTomcatWebApp/Servlet so the request would look something like this: from webappTomcat an ajax request to http://localhost/webappApache/pythonProxy.py?url=http://localhost:8084/anotherTomcatWebAppServlet?parameterX=345parameterY=199 Is there some configuration needed on tomcat for this to work? Keep in mind that this is not a real proxy(ie, no cacheing or anything like that). We were thinking that perhaps a java proxy(residing in tomcat) that makes a call to the python proxy(residing in apache) would be what we need but it seems kind of hacky. Thanks in advance!

RE: Can Tomcat be used to host socket servers?
In other words instead of committing to single port request TC use a port range for connector?

Yeah thanks Filip, I read online about that being the problem.
I think I am now ready to setup the IDMS so that it will listen to JDBC

just to say one more thing: this only happens when cfusion war is deployed in tomcat. If i try to shutdown without cfusion.war deployed, everything works fine.

Re: Can Tomcat be used to host socket servers?
Well what I want is to have a dedicated port for a socket, I just want all the application infrastructure to be handled by Tomcat rather than a writing a custom solution. Not sure if dynamically rewriting server.xml is the way to go. My guess would by a Valve/Connector type thing, but I'm just not that familiar with Tomcat. I can't be only one who has had this issue. The situation is that we have some existing programs (written in C) that are socket servers. I want to redo them in Java, and having Tomcat host them would be great because I could focus solely on the parts of the program than do request processing and leave the housekeeping to Tomcat. In other words, I want to write servlets that are faux-sockets.

The quickie answer is to add a line echo catalina.sh : JAVA_OPTS = $JAVA_OPTS /var/log/tomcat_debug_file.log to the beginning of your catalina.sh, and see what comes out. The better answer : To start Tomcat, you must use a command like /etc/init.d/tomcatxx start yes ? If so, then look first at that script, and follow the chain of scripts that itself calls. Depending on the system you are using, there may be other files that are read in during startup and which define options such as JAVA_OPTS. Under Linux e.g., look in the /etc/default dir. The thing is, there are so many different platform flavors and setups and ways to start these things, that there is no easy answer. You will have to piece the puzzle together yourself. On my Linux Debian systems, the chain is roughly as follows : /etc/init.d/tomcat5.5 does some stuff, then reads /etc/default/tomcat5.5, then does some more stuff, then calls up /usr/share/tomcat5.5/bin/startup.sh, which itself calls /usr/share/tomcat5.5/bin/catalina.sh, which itself runs /usr/share/tomcat5.5/bin/setenv.sh.

Yes Are you logging out programmatically, using the servlet method request.getSession().invalidate(), or are you just clearing cookies? I invalid the session programmatically... correct. Your primary problem sounds like you have placed some CSS or script files somewhere in a protected directory and the browser is requesting them without providing the correct authentication credentials. Tomcat returns the *first* file you requested inside the secured area after authentication is completed. So for some reason your browser is requesting a script or CSS file before the JSP page. Are the script and CSS files in an unprotected directory? youa re absolutly correct, basically the senario is like this: basically the page is including link rel=stylesheet type=text/css href=/app1/resources-folder/style.css / So the browser should apply the style to the page, but instead it outputs the actual file to the broweser. So it should the style.css from the jsp file.

Re: Can Tomcat be used to host socket servers?
Thanks for cogent reply, Chuck :) By socket servers, I mean the existing programs are bound to a particular port number and just sit there waiting for requests. The port numbers are arbitrary, and I'm not knowledgeable enough of networking to know whether they use HTTP or not. I'll probably just write stand alone Java sockets servers and simply bounce incoming requests over to a servlet I'll develop to do the heavy liffting. The reason I would have liked Tomcat to handle the whole shebang is that now I'll have to adjust each system that hosts these sockets to automatically invoke them when they restart. Kinda tedious.

Do you mean they simply do a listen/accept on a server socket, waiting for connection requests from some client? If so, what protocol is being used? If it's not HTTP (or AJP), Tomcat won't help you.

By socket servers, I mean the existing programs are bound to a particular port number and just sit there waiting for requests. The port numbers are arbitrary How do they get assigned? When you say the program is listening for a request, does it have a socket_read or socket_accept up? (The first is looking for data, the second for a connection request.) I'm not knowledgeable enough of networking to know whether they use HTTP or not. That's a rather critical factor to determine whether or not you can simply pass on the request to a servlet. The reason I would have liked Tomcat to handle the whole shebang is that now I'll have to adjust each system that hosts these sockets to automatically invoke them when they restart. Kinda tedious. You won't be able to use a stock Tomcat to listen/read on those ports, but you could still package your socket servers inside a webapp. A ServletContextListener inside the webapp would likely have to create a thread for each port of interest, and those threads could connect with the standar Tomcat port to pass on HTTP-formatted requests. Your clients would have to expect HTTP as a response, or your server threads would have to convert the response to whatever protocol the clients do expect. You could also write your own Tomcat connector to do the above, rather than a webapp, but you would then be pretty much tied to a specific level of Tomcat. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Might I recommend that you use a regular class instead of one with
static members and methods? I think you'll find it more flexible (for
instance, you will be able to extend the class and replace the object in
memory with the extended class, or you could wrap one object in another,
etc., neither of which are possible with static methods).
You could just create a new instance of this class (BeanBag) at app
startup and toss it into the application scope.
In the Servlet code, I just obtain a bean like this:
AppleBean appleBean = BeanBag.getAppleBean();
It would be a bit more complicated, but your new code would be:
BeanBag bb = (BeanBag)application.getAttribute(my.package.beanBag);
AppleBean appleBean = bb.getAppleBean();
If you're feeling sassy, you could implement a getAppleBean() method in
a superclass from which all of your servlets extend, and clean up your
code a little bit more. Tres' objectique!
My question is: where (or if) should I implement the synchronization?
Synchronize the methods of your BeanBag class (whether static or not).
But wouldn't making the methods in BeanBag synchronized be a better
approach?
In the example, the bean in question was an application-scoped bean,
which requires synchronization in the generated Java code itself
(because there is a null check for the reference and the possibility of
creating a new object and inserting it into the application scope). Your
solution will have a single object in the application scope (or will be
a static singleton) and therefore the synchronization can be handled
locally (in the class).
Hope that helps,

RE: How to have multiple loggers with shared code also using the logger?
Because of the classloading hierarchy. Once the logger is
initialized with the common classloader, everybody uses that
one.
Thanks. I studied the Apache logger code.
When we call org.apache.log4j.Logger.getLogger(), it calls functions of
LogManager. The static initializer block of LogManager gets log4j.properties
using the thread's class loader, so if the first webapp I run is mywebservice,
then it will get log4j.properties from mywebservice, such as
mywebservice/WEB-INF/classes/log4j.properties. The root logger will be
initialized using this log4j.properties file, and all new loggers will inherit
this configuration, which does not seem very useful.
And since the log4j.jar resides in the ${catalina.home}/lib folder, this root
logger is used by all web apps.
So what I did is
(1) Create a log4j.properties in ${catalina.home}/lib/log4j.properties or in a
jar file here.
(2) This properties file should contain the configuration shared by all app
loggers. For me, the file is one line:
log4j.rootLogger=warn
(3) Rename log4j.properties in each webapp and swingapp and JUnit test app to
log4j_app.properties.
(4) Modify MyLog.getLogger(), which is a function in a jar file that is shared
by all apps (ie. a function in ${catalina.home}/lib) so that when a logger is
created, initialize the logger from the appropriate log4j_app.properties.
import org.apache.log4j.PropertyConfigurator;
/**
* This function attempts to locate log4j_app.properties using the
* thread's classloader, and returns a logger using the location of
* log4j_app.properties as the logger name.
* The logger will be initialized with the configuration in
log4j_app.properties.
* This allows each application within the web server will use its own
logger.
* This function is thread-safe, and callers don't need to synchronized on
MyLog.
* @return
* @throws NullPointerException if log4j_app.properties does not exist
*/
public static Logger getLogger()
{
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
URL log4j_properties = classLoader.getResource(log4j_app.properties);
String loggerName = log4j_properties.toString();
synchronized (MyLog.class)
{
Logger logger =
Logger.getRootLogger().getLoggerRepository().exists(loggerName);
if (logger == null)
{
logger = Logger.getLogger(loggerName);
PropertyConfigurator.configure(log4j_properties);
System.out.println(Created logger: loggerName= + loggerName);
}
return logger;
}
}
Don't do that. Keep just one copy of the source
somewhere, just have your packaging script put the .class
file in the webapp package. No need to have an abstract
class or subclasses.
Not sure if that would work as the log4j.jar is in ${catalina.home}/lib, so the
root logger is shared by all apps.
(1) Pass a logger from the webapp to the common code
-- ie.
to add a Logger argument to all the functions in the
common
code, but this sounds tedious.
That's the cost of keeping things isolated, which is a
worthwhile goal.
(2) In each webapp have a filter that sets a thread
local
variable like ThreadLocalLogger threadLogger.
Just make sure you clear the ThreadLocal on *every*
possible exit path out of your request processing. If you
don't, you will have memory leaks in PermGen causing it
to fill up as webapps are redeployed.

And since the log4j.jar resides in the ${catalina.home}/lib

The log4j.jar is only there because you put it there. It does not come with
the Tomcat distribution, and it's normally placed in the WEB-INF/lib directory
of each webapp that needs it.
By having such a jar in a common location, you've pretty much guaranteed that
you'll have to take Tomcat down to redeploy a single webapp - the old webapp
won't go away because log4j will be hanging onto references to it. (A common
cause of PermGen filling up after redeployments.)
The servlet spec (and experience) strongly suggest that webapps be kept as
isolated as possible for this kind of reason.
