RE: using struts datasource from a servlet
You can either pass the datasource from your servlet/action as a method parameter or you need to register the datasource somewhere that the class can access. That might be using JNDI, in which case you probably don't need to configure your datasource in Struts but in your container. Another option would be to configure the DS in struts but register it with a singleton (Service Locator) that can retrieve the datasource in your data access classes.

RE: using struts datasource from a servlet
Struts stores the datasources as servlet context attributes. You can access the default datasource in your servlet using - (DataSource) getServletContext().getAttribute(Globals.DATA_SOURCE_KEY); Take a look at the struts-config dtd for more info (particularly if you use modules) http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd Steve > -Original Message- > From: Richard Raquepo [mailto:[EMAIL PROTECTED] > Sent: June 29, 2003 11:22 PM > To: Struts Users Mailing List > Subject: using struts datasource from a servlet > > > can i call/use the a struts datasource in my servlet. > > the thing is, i have a struts app. then i created a servlet to do > some specific thing. now my question is, > can i use the datasource defined in my struts config file in my > servlet. if so, how? example code will > be very much appreciated. > > thanks. > > -richard - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
using struts datasource from a servlet
can i call/use the a struts datasource in my servlet. the thing is, i have a struts app. then i created a servlet to do some specific thing. now my question is, can i use the datasource defined in my struts config file in my servlet. if so, how? example code will be very much appreciated. thanks. -richard
Re: DataSource problem
Maarten,
do you declare the JNDI resource within the context tags for your webapp
in server.xml, or within the global-naming-resources tags? I'm using the
same setup as you with my JNDI declared in the globalnamingresources
and it wouldn't work until I put a resource-link tag in the context tags.

As a side point, you should probably put all such logic into a session
bean(s) that your action classes can call. Aside from this being a
more 3-tier architecture it should allow you query your container (for

Are you using Tomcat 4.x without DBCP from the Jakarta Commons to get the

Subject: DataSource problem
Hi,
I'm trying to create a simple DataBase app. using Struts. Right now i
have a
problem with getting the DataSource out of the InitialContext and i'm not
sure what i'm doing wrong or maybe it has something to do with the Struts
Servlet.
In configured the server.xml as follows:
user
root
password
driverClassName
org.gjt.mm.mysql.Driver
driverName
jdbc:mysql://localhost/test
and my web.xml includes the following:
test
javax.sql.DataSource
CONTAINER
In an Action-class i do this:
Context env = (Context) new
InitialContext().lookup("java:comp/env");
DataSource ds = (DataSource) env.lookup("test");
Here the DataSource keeps ending up as NULL. When i do this:
Connection con = DriverManager.getConnection(Commands.DB_TEST_URL,
Commands.DB_TEST_USERNAME, "");
things are working fine but i have no idea where to look. The Context
does seem to have a reference to the 'test' reference but nothing more.
Does this have something to do with Struts or did i forget something? I
don't want to use the struts.xml for a database-connection. One of the
reasons is that i keep getting the message that it can't find the driver,
while it is included in the CLASSPATH.
Hope someone can help,
Maarten

Re: Accessing struts datasource outside action servlet
You can store the DataSource in JNDI. An easier way is to configure some

Re: Design and Datasource question
subclass dispatch action. in execute method store the results from your jndi lookup in the servlet context then pass it to your data access objects which will then get connections from container pool(or your own). you only want to do the lookup once. if its ejb, you'll need to duplicate similar arrangement in that container. - Original Message - From: "Tolle Krez" <[EMAIL PROTECTED]> To: "Struts Users Mailing List" <[EMAIL PROTECTED]> Sent: Wednesday, February 05, 2003 8:42 PM Subject: Re: Design and Datasource question > I dont think it is good practice to pass datasource from Action class to your business > beans. > http://marc.theaimsgroup.com/?l=struts-user&m=104333643909577&w=2 > http://marc.theaimsgroup.com/?l=struts-user&m=104182416102397&w=2 > > I feel using JNDI to get datasource is the best choice.

It won't matter on Tomcat (which doesn't support these features), but it allows high-availabity servers to support transparent reconfiguration of existing connection pools, or even switching to a backup database, without making you shut down your application. Saving a reference to the connection pool you were given earlier makes all of that kind of support difficult to impossible. > Thanks, > Charlie Craig -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
Re: accessing DataSource, webapp design question
The value objects shouldn't know about the ServletContext so you'll need to use JNDI. JNDI doesn't tie your objects to any particular environment. My value objects don't know about the database at all. Each VO has a Mapper (or DAO) associated with it. I configure my mappers with the DataSource so they can persist the objects. This removes all persistence code from the VOs and allows pluggable persistence layers. I'm using JDBC now but could move to EJB, OJB, JDO, etc very easily.

Using the element in your struts-config.xml file does *not* support the use of JNDI to retrieve it. JNDI is only used for data sources managed by your container. For Tomcat 4.1, for example, see: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-resources-howto.html http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-howto.html The instructions for setting up your web.xml file, and for accessing the data source in a program, are portable across any container that supports JNDI based data sources. The administrative stuff to configure them is specific to the container. To access your from an Action, you'd simply say (Struts 1.1): DataSource ds = getDataSource(request, "FIELDSTONE"); Craig On 5 Jan 2003, Nick Torenvliet wrote: > Date: 05 Jan 2003 21:34:48 -0500 > From: Nick Torenvliet <[EMAIL PROTECTED]> > Reply-To: Struts Users Mailing List <[EMAIL PROTECTED]>, > [EMAIL PROTECTED] > To: Struts Users Mailing List <[EMAIL PROTECTED]> > Subject: Re: getting a datasource in a bean > > Sounds like a plan,I've never worked with javax.naming packages before > though, I've got the following datasource > > > key="FIELDSTONE"> > > > property="autoCommit" > > value="false"/> > > > property="description" > > value="Example Data Source Configuration"/> > > > property="driverClassName" > > value="org.gjt.mm.mysql.Driver"/> > > > property="maxCount" > > value="4"/> > > > property="minCount" > > value="2"/> > > > property="password" > > value=""/> > > > property="url" > > value="jdbc:mysql://localhost:3306/wessuc"/> > > > property="username" > > value="root"/> > > > > Cound you give me some example code that uses JNDI to get a connection? > > ~/nick > > > On Sun, 2003-01-05 at 17:46, Max Kremer wrote: > > You can just look up the JNDI datasource in your bean. > > - Original Message - > > From: "Nick Torenvliet" <[EMAIL PROTECTED]> > > To: <[EMAIL PROTECTED]> > > Sent: Sunday, January 05, 2003 4:51 PM > > Subject: getting a datasource in a bean > > > > > > > Hi, Just as in the examples on the struts site I've succesfully > > > configured a mysql datasource and had it print the results of queries > > > from out of an action class.

getting a datasource in a bean
Hi, Just as in the examples on the struts site I've succesfully configured a mysql datasource and had it print the results of queries from out of an action class. I am using struts 1.1-b2. I want to replace my current dbpooling(I wrote last year)with the struts datasource and dbcp, I am having one problem though. I can't get a connection in my beans to the database because I have no access to the getDataSource(request,key) method. Since my pooling methods were hard wired I just went in to the database by passing a database name to the methods. The stock answer is to pass a connection to the bean, but that means I'll be rewriting a lot of code. How can I access the datasource from a bean? ~/nick -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>

In addition, the logic required to get a connection from the pool does *not* need to have a reference to the DataSource or ServletContext, which means your business logic can become more insulated from the web tier. Further, the JNDI data source itself is configured external to your webapp, so you don't have to tweak the web.xml file to adjust for differences (example - you can install the exact same webapp on a development, test, and production server without having to tweak it to connect to the correct database.) Finally, using JNDI means that you'll automatically take advantage of the connection pool provided by your app server container (if you ever run on something other than Tomcat), which is likely to be optimized for performance on that container. The only downside to using JNDI is that your business logic *must* run inside a container that provides the JNDI services, or your app must otherwise supply one.

If you don't know what they are, then you probably aren't using them :) .
It's a mechanism that allows you to subdivide your Struts application into
pieces, each with their own config file.
If you're not using modules, then I don't know what the problem could be.
Perhaps you could use your debugger to trace the loading of your

Re: Oracle DataSource Tips
One tactic I have used is to create a singleton data access class (e.g. DataCache) which provides methods that return data as beans (not action form beans). The DataCache class gets initialized in a Struts plug-in. Plug-ins execute once when the application starts and once when it shuts down, and require Struts 1.1. The beans can do the business logic processing as needed. The plug-in has access to the servlet context so can access the datasource defined in struts-config.xml or in the servlet container configuration file(s).

Oracle DataSource Tips
Since it took me several hours to catch this bug, I thought I might pass it along to anyone using Oracle as a datasource for the Struts application. The OracleDatSource and OraclePooledConnectionDataSource classes use standard Bean naming conventions for getters and setters. The url property, however, uses setURL and getURL for the setter and getter respectively. Therefore, the set-property element in the datasource clause should be instead of . A valid datasource definition that is working for me is: The xxx.xxx.xxx.xxx value is an IP or resolvable hostname for the oracle server. 1521 is the port to use. "a" is the instance name for the database. The key is an arbitrary string. If you choose instead to use the default connection pool from Struts (via the Commons database package) then the ping that works for Oracle is "select 1 from dual". Dual is a virtual table in every Oracle instance. Brad -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>

Hmm, I don't see anything wrong with that. What version of Struts are you using? You should check the struts-config_1_1.dtd (or appropriate version number) for available elements and attributes.

something else to store multiple DataSources.

Re: Multiple DataSource Problem
Ok , I thought I have already changed the key value's to "MRA" and
"PHONE_DB" in both of my data-sources, what I am having trouble with is how
do I refrence these values in the form and action classes?

Please respond to

That would store the DataSource under the Struts default value, which
obviously only allows for one DataSource. Just change the key value to
something else to store multiple DataSources.

Utilizing the Struts DataSource from a listener

Re: accessing DataSource from custom tag
i think i understand now why doing sql in a custom tag would be bad. i am going to use your approach and create a utility bean that has getter methods to get the html:select option fields from the database, and add the bean to the session context. i will do this in the same Action class that creates and populates the form bean that requires those option fields. thanks.
