urgent - data-source and container managed datasource
Hi There, I'm getting ready to ship off my application and I'm trying to use the application server (standalone oc4j) to hold the data source information instead of having it in struts-config.xml. Is this possible? When jDeveloper deploys to the server it builds me a data-sources.xml file which I presume is correct. When I test the connection, its fine. In web.xml I entered: resource-ref res-ref-namejdbc/bartCoreDS/res-ref-name res-typejavax.sql.DataSource/res-type res-authContainer/res-auth /resource-ref Where jdbc/bartCoreDS matches the location entry of the data-source in data-sources.xml. Then I took out the data-sources from struts-config.xml. I'm not terribly surprised that now my application can't find the database. The problem is I don't know where to look for instructions on how to do this or if its even possible. Is there a way to put a data-source configuration in struts-config.xml that tells it to look at the container, so that the username and password aren't in it?? If I can provide more information, I will. Time is running a bit short, so I'd really, really appreciate a quick response.

Re: urgent - data-source and container managed datasource
Hello,
I have configured my data source on OC4J standalone
version. Given below are snippets from the relevant
files:
In my data-sources.xml , I have
data-source
class=com.evermind.sql.DriverManagerDataSource
name=TestDS
location=jdbc/OracleCoreDS
xa-location=jdbc/xa/OracleXADS
ejb-location=jdbc/TestDS
connection-driver=oracle.jdbc.driver.OracleDriver
url=jdbc:oracle:thin:@servername:1521:test
username=username
password=password
min-connections=5
max-connections=20
inactivity-timeout=30
/
I lookup this data source in a DatabaseServlet,
which is loaded on server startup, and intialize a
static variable in my DBConnection class, which
manages database connections.
I use the code below:
snip
InitialContext ic = new InitialContext();
DataSource ds =
(DataSource)ic.lookup(jdbc/TestDS);
..
DBConnection.dataSource=ds; //initializeDataSource in
the DBConnection class
snip
In my DBConnection class, I have methods like
openConnection(), closeConnection() et al to handle
connections from the data source.
snip
public Connection openConnection()
{
Connection con=null;
try
{
con = dataSource.getConnection();
}
catch(Exception e)
{
System.out.println(Error: Unable to get
connection + e.getMessage());
}
return con;
}
snip
In order to load the DatabaseServlet on starup, I have
the following in the web.xml file:
servlet
servlet-namedatabase/servlet-name
servlet-classobs.application.DatabaseServlet/servlet-class
load-on-startup1/load-on-startup
/servlet
HTH,
Shyam

DataSource help
Hi All,
I have a problem regarding the DB connection. In my application i want to log the
session time for each session. For that I am using the Session Listner in web.xml
somthing like:
listenerlistener-classactions.SessionListenerAction/listener-class/listener
My problem is:
In my struts-config.xml file I have data-sourceset-property defined for my
database.
what I am thinking is to call Insert query in
public void sessionCreated(HttpSessionEvent event) { }
and update query public void sessionDestroyed(HttpSessionEvent event) {} function
But my problem is how to get and pass the DataSource that refers to my DB defined in
datasource tag of struts-conf file to my DAO file.
WHAT I TRIED IS:
String name = event.getName();
HttpSession session = event.getSession();
ServletContext sc = session.getServletContext();
try{
DataSource dataSource =(DataSource)sc.getAttribute(Action.DATA_SOURCE_KEY);
UpdateSessionListenerDAO dao= new UpdateSessionListenerDAO(dataSource);
dao.insertSessionLogging(session.getId().toString());
}catch(Exception e){
System.out.println(ERROR + e.getMessage());
}
But this is not working I was not able to figure out the reason.
Pls help..

RE: DataSource help
put a trigger on the data table you are selecting from, that inserts a timestamp in to
a timestamplog table, when a select is done on your data table. Or create a view and
put a trigger on that, to preserve the functionality of the data table (ie not have a
trigger fire when you are just doing dev etc.)

Accessing Struts Datasource from another action servlet
Hi Guys, I have a web application written in Stuts and am writing a scheduler which is a seperate action servlet which is configured in the web.xml file to start at startup. All of my other action classes are session based so they can get the default datasource (From the struts-config.xml) from the session using; DataSource ds = getDataSource(request); I also store this datasource in the session so that I can access it from jsp's or pass it to other standalone servlets for background database processing and this approach seems to work well. I can't use this approach for the scheduler though as I can't guarantee that anyone will start a session so I can pass the datasource. My question is, how do I use the struts datasource in my scheduled servlet? Thanks for any help!

Re: Accessing Struts Datasource from another action servlet
have you not seen the threads regarding the struts datasource? the party line seems to frown upon it as it encourages breaking with MVC, unless you pass the connection up to the model tier. that said, in your shoes I'd configure a datasource in the second webapp (albeit with the same config values) rather than trying to pass from one to the other. I'd also suggest that storing datasources in the session isn't ideal but thats just my opinion.

Matthias, Thanks very much for responding! It seems there's a misunderstanding on my side. I guess I'll have to rethink it. From what you say, there isn't any reason to include a data-sources element in struts-config since the persistence layer should be invisible to Struts. Am I understanding you correctly?

RE: REPOST: newbie datasource config problems
jim, in 1.2 there is no GenericDataSource. (because legacy.jar will be removed) you can still use a DataSource with BasicDataSource. after 2.0 it will also be moved away (see the faq) with the datasource, you write JDBC in an action-class. do you really want it ? :-) in my case i use (allways) a delegate-class, which handles OJB (for storeing und getting objects from a database) or EJB. but action only speaks with interface of my delegate see also http://java.sun.com/blueprints/corej2eepatterns/Patterns/index.html for delegate and other patterns inclusive of DAO. cheers, -Original Message- From: Jim Anderson [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 28, 2004 7:29 PM To: Struts Users Mailing List Subject: Re: REPOST: newbie datasource config problems Matthias, Thanks very much for responding!

LDAP + DataSource

Re: LDAP + DataSource
LDAP, as the name implies, is a Directory Access Protocol. As such, you cannot use JDBC to establish connections.

Struts-config.xml contains the following lines: data-sources data-source key=test type=javax.sql.DataSource set-property property=autoCommit value=true/ set-property property=driverClass value=com.mysql.jdbc.Driver/ set-property property=maxCount value=6/ set-property property=minCount value=2/ set-property property=user value=username/ set-property property=password value=pasword/ set-property property=url value=jdbc:mysql://localhost:3306/test/ /data-source /data-sources At the end of web.xml, I have added the following lines: resource-ref res-ref-namejdbc/test/res-ref-name res-typejavax.sql.DataSource/res-type res-authContainer/res-auth /resource-ref When I reload the application, tomcat\logs\stderr.log contains the following lines: java.lang.InstantiationException: javax.sql.DataSource at java.lang.Class.newInstance0(Class.java:293) at java.lang.Class.newInstance(Class.java:261) at org.apache.struts.util.RequestUtils.applicationInstance(RequestUtils.java:23 1) .. and when I try to run the application, the browser displays this message: The requested service (Servlet action is currently unavailable) is not currently available. When I remove the datasource, there are no problems. How can I check why instantiating of the DataSource fails and where do I make a mistake?

RE: Datasource problem
Thanks Mathias, just after I sent the email I got it working using the key as you suggested. I tried using the key earlier today and it didn't work, probably I had some other problem which I accidentally fixed and now I've confused myself. Shouldn't it work without the key since I only have the one datasource and all the docs I've seen don't require the key. My understanding is that the key is only required when there is more than one datasource. No? Thanks for your help.

RE: Datasource problem
Hi Matthias, Thanks for all the info. As you said that only one can be defined without a key hence if I use getDataSource(req); then it should use the default datasource without me having to specify the Globals.DATA_SOURCE_KEY as the second parameter. So looking at my struts-config.xml there is only one datasource hence my reading is that the second parameter is redundant. Also Globals.DATA_SOURCE_KEY is showing as deprecated so I was avoiding using it. Looking at it further I see that part of my problem was that I am using JBuilder X which adds a key by default, once that key is added DATA_SOURCE_KEY doesn't work, so obviously the key is the problem. Once I remove the key I can use the single parameter. Thanks for your help!

Re: Oracle DataSource configuration
The exception you see is an indication that the factory doesn't see the ResourceParams you have specified. Try to print out the url and driverClassName properties of BasicDataSource, you will see they are null. You have an extra /ResourceParams tag there in your definition of the server.xml file. Is that just a copy/paster error? Maybe you can post the whole context You should also try without a resource-ref in web.xml.

Quoting e-denton Java Programmer [EMAIL PROTECTED]: Merry Christmas, Wow, I finally connected to my data source! Now, I want to put the code somewhere it will be executed only once, and save the DataSource object where Actions, beans, etc. can get at it. That way, I don't have to perform the lookup all the time. That turns out not to be the recommended pattern, for at least two reasons: * If your app server supports the ability to dynamically reconfigure DataSource objects while your app is running, the object retrieved via JNDI might change each time. * If you retrieve it once and then put it someplace (such as in a servlet context attribute) then any code that wants to retrieve it will need a reference to the ServletContext object (and therefore be dependent on the servlet API). Any suggestions on where to put the one time setup code, and where to save the DataSource object reference (in the application?). Consider setting up a utility class with a public static method called getDataSource() that actually does the lookup every time. Then you can call it like: DataSource ds = MyUtils.getDataSource(jdbc/TestDB); or, even go a step farther and have it return a connection for you ... that way you're hiding how the connection pooling is being done as well, and just operating at the SQL level.

Re: How find DataSource?
Wow, my personal saga of discovery continues... Apparently I have been trying to set up connection pooling *both* in server.xml context *and* in web.xml unnecessarily. Well, the server.xml works, but then I have the problem of where to store the DataStore object and how my Data Access Objects will access it. Has anyone set up a connection pool using web.xml? Steps? Examples? Tips? I can't even seem to change the driver without problems. And, web.xml doesn't use JNDI, does it? Has anyone used server.xml instead? Where did you keep the DataSource Object? I looked into keeping it in the session, but then I have to pass session to my DAOs--ick. (I am writing my own DAOs.) Vic, I might have two problems with keeping it in a static block. 1. My container can be passivated, so everything must be serializable. 2. I hope to only look it up once for efficiency's sake. Martin, I assume you mean to extend DynaActionForm and override initialize, but that means tying myself to Struts. (Like I'm not already!) Ideally, I shouldn't have to modify the framework.

Don't spend the time to get DataSource working. It is deprecated and will

Re: HELP: about to get datasource of struts and pass to logic bea ns...
Ah a small comment... The Struts DataSource should not be used, I agree;
the J2EE container DataSource should be used; but it will not be
removed for a while AFIAK.
(Deprecated just means it might be removed in some futre version. Just
like hopefully bean, logic and html:link get deprecated in 2.0 in favor
of JSTL. It's just a nudge from developers (of which I am not one) for
you to start considering the better alternatives. I even think Java
should deprecate Connection , ResultSet and java.util.Date in favor of
DataSource, RowSet and Calendar)
Poolman is very, very nice... I used it before 2001; when I switched to
RowSet (before I started using a SQL based DAO). DAO is best thing to do
now, and all the DB issues would disapper.

I'm not sure what problem you are experiencing, but I am pretty sure that it is not recommended that you use the GenericDataSource.

Deprecation - DataSource
First hello everyone !!! This is my first answer and i'm learning struts now... I'm using this method but it's deprecated...Did someone knows the right call ? thx. DataSource dataSource = (DataSource)servlet.getServletContext().getAttribute(Action.DATA_SOURCE_KEY);
Re: Deprecation - DataSource
You can use the jndi datasource that you define in web.xml rather than struts. http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource- examples-howto.html The struts datasource is deprecated generally. Ideally you have your db connection stuff in your model layer. If this means little to you, then just use the jndi datasource for the time being while you become more familiar with struts. I'm sure a few weeks down the line you'll see what the model - controller separation stuff is about, when your actions start getting longer than is ideal. Hope this helps Cheers Mark On Monday, October 27, 2003, at 01:47 PM, Mathieu Grimault wrote: First hello everyone !!! This is my first answer and i'm learning struts now...

Re: Please Please Help! -- DataSource Error
Paul: This might occur if you have multiple copies (perhaps differnt versions?) of struts.jar in your classpath. Make sure you have one and only one struts-jar in your WEB-INF/lib directory and that you compile against *that* jar. (Remove all other extaneous ones.) Recompile your app (if necessary) and then restart tomcat. This may resolve your problem..

Short answer -- you don't.
The Struts data source isn't magical -- it's an object like any other
object, and in order for a method in some bean to talk to an instance,
the method needs a reference to that object. Typically, that means
you need to pass it in as a method parameter, make it visible through
some static getter or factory method, or make it visible in some
global repository that is available to the bean instance.
Using JNDI-based data sources is an example of the third approach.
Indeed, that is one of the main reasons that using JNDI data sources
should be preferred to using the one provided by Struts -- your method
inside SomeBean can ask for the data source whenever it needs to,
without having to pass it around. (There are other advantages as
well, but this is the one most relevant to your concern here.)
So, when ever you neet a datasource, the method in SomeBean will have to
search it in JNDI. Doesn't this pose a performance penalty?

The JNDI environment is a glorified HashMap, so it's not like this is
particularly expensive. Certainly no more expensive than modifying all
your beans to pass along a DataSource or Connection parameter to any
method that needs it.

Any hints?
Short answer -- you don't.
The Struts data source isn't magical -- it's an object like any other
object, and in order for a method in some bean to talk to an instance,
the method needs a reference to that object. Typically, that means you
need to pass it in as a method parameter, make it visible through some
static getter or factory method, or make it visible in some global
repository that is available to the bean instance.
Using JNDI-based data sources is an example of the third approach.
Indeed, that is one of the main reasons that using JNDI data sources
should be preferred to using the one provided by Struts -- your method
inside SomeBean can ask for the data source whenever it needs to,
without having to pass it around. (There are other advantages as well,
but this is the one most relevant to your concern here.)

JNDI Datasource
Dear All, I am facing following error, when i am trying to connect jndi data source. error is Cannot load JDBC driver class 'null'. here i am using Mysql database, i have copied mysql driver jar files into struts application's lib folder , tomcat's common/lib and shared/lib folder and Jndi datasource is configured in server.config,, can any one pls. help me to correct my mistake..

R: [OT] JNDI datasource lookup to test classes
The most common solution to this problem is using a Factory Method to
return the correct implementation of the interface. Your classes should
never know which implementation is in use because they will all ask the
Factory Method for the object. You just need to change the one line in
the method to return a different object for testing.
Ok, you mean something like that:
Class ConnectionHandlerFactory
...
public IConnectonHandler getConnectonHandler()
{
if (test)
return new ConnectionHandlerTest();
else
return new ConnectionHandlerForTomcat();
}
but I think this has 2 problems:
1) in my production code I'll have code that is written just for testing
purpose
2) Before executing any test I have to set the test variable to true.
Or I did not understand?

That's the gist of it. We've solved it thusly:
if (Boolean.getBoolean(use.test.objects)) {
try {
return = (IConnectonHandler)
Class.forName(
path.to.ConnectionHandlerTest).newInstance();
} catch (Exception e) {
log.fatal(Unable to create Test object., e);
throw new RuntimeException(e);
}
} else {
return = new ConnectionHandlerForTomcat();
}
So when we're executing our tests we set the property
use.test.objects=true. It uses Class.forName() to create the object
instance so that it doesn't have to know about the test object at
compile time or production runtime.
We also keep our testcase source in a separate, though parallel, tree in
the filesystem. That lets us easily build a production jarfile that
doesn't include any of the testcase classes.

Re: R: [OT] JNDI datasource lookup to test classes
Alternatively,
If you are worried about test code in production, you could extend from
ConnectionHandlerFactory with a TestConnectionHandlerFactor and override
the getConnectionHandler() method to return the connectionHandler for
testing.

Struts stores your DataSources in the ServletContext under the Globals.DATA_SOURCE_KEY attribute (you can change this name in the data-source element. You can retrieve them just like any other object you store in the ServletContext.

Best way to retrieve data from a datasource
Following on to a earlier question, what is the reccomended way of retrieving a ResultSet and passing it to be viewed on a JSP page? I have seen it done using ProcessBeans, Array Lists, ResultLists, Collection and it all seems a bit confusing. In my app, the user enters a SQL query so I have no idea the structure of the data that will be returned. Thanks in advance Chirag -- NOTICE: If received in error, please destroy and notify sender.

Re: retrieving DataSource in struts
Before rolling your own, you might want to take a look at some of the ORM projects, like OJB http://db.apache.org/ojb/ and Hibernate http://hibernate.bluemars.net/, or a DAO framework, like ibatis http://ibatis.com/. These sorts of things are always more work than they seem at first. -Ted.

how to access my datasource from a securityfilter realm?
I found a reference to the SecurityFilter project on this mailing list. I just hooked it up, and it seems to work pretty well. I do have a question, though. Is there any way for the realm to use same datasource as struts? I'm not passed anything useful. Is there something static somewhere that I can access? I could pass the connection information in as parameters to the realm, but then I've got the same config information in two places and I'm not using whatever nifty pooling is provided by struts' datasource.

Subject: using Struts datasource from a normal servlet
i have a service class that i can use in my actions by passing the servlet
variable to it
MyService service = new MyService(servlet);
or
MyService service = new MyService()
service.setServlet(servlet);
this works fine on my action classes. My question is
how can i use this service in a normal servlet.
public class MyServlet extends HttpServlet{
}
how can i pass the servlet variable and how to get it so i can use my
service in a normal servlet. Please help me
thanks.
