Obtaining object initialized in contextlistener in non servlet-object

Hi, I don't know if this is the correct forum so I'll give it a try.
I'm currently developing an n-tier webapp. At initialisation I would like to initialize a ConnectionPool object I made and put it into a session object at context initialization in a ServletContextListener class. The ServletContextListener class is initialised directly at the startup of Tomcat or other JSP engine. I would like to do this so when I need the connectionpool object I don't have to create it again, but instead get it from the session. Has anyone done this already or is there a better, cleaner way to access such an object? Best way would be to not put it in a session but making it globally accessible once it isneeded. Can anyone help me with this?
Hope someone can help. Thanks. Michiel.

But I was wondering if by implementing it as
a singleton, how does the JVM know that there is
already an instance available once there is?If you implement the singleton correctly you will have one instance per classloader. Since all your classes will likely have the same classloader when you call getInstance you will retrieve the same singleton instance.
If Ido implement it in Tomcat, how will then get a
connection in an object wihtout passing it though a
JSP/servlet?You construct an initial context and do a naming lookup. There are examples in the link I posted.

Non servlet to use resource

Hi all,
is it possible for non-servlet classes (located in WEB-INF/classes) to load/use resource of web application just as Servlet doing with getServletContext().getResource() ?
I am using Tomcat 6.
Any hought would be really appreciated.
thanks

It is better to use the Class.getResourceAsStream method or the ResourceBundle.getBundle methods to locate resources in the classpath. You could pass the servletContext object to the other classes but this violates the separation between presentation and business logic and should be avoided.

Retrieve ServletContext from non-servlet class

A servlet calls a method which is located in another class which is not a servlet. Within this method of the non-servlet class, i need to access the ServletContext of the servlet that has called the method. What i am currently doing is simply passing the ServletContext as a parameter to the method.
I would like to avoid passing the ServletContext all the time, so i'm wondering if it's possible, from the non-servlet class, to retrieve the ServletContext of the servlet which has called the method of the non-servlet class.

Thanks J-Fine, that's a smart suggestion. BTW in the meantime i figured out that passing the ServletContext is not that bad idea, after all it reflects the structure of the app. However if i'll change my mind again i'll do like you suggested.

Add non-servlet class to Tomcat

Hi,
does anyone know, what I have to do, to be able
to use a simple non-servlet class file in my
jsp-pages.
e.g.
MyClass.class
In my jsp page:
<%
MyClass m = new MyClass( );
%>
I was told that I simply have to put it in the
web-inf/classes directory, but that doesn't seem
to work ...
Any help would be appreciated! Thanx. chris

You need to use the "import" statement or else use the full class name. Also, some servers don't handle the default package well so you may want to try placing the class in a package.
e.g. if class is mypackage.MyClass, it is placed in web-inf/classes/mypackage/MyClass.class
In the JSP, code:
<%@ page import="mypackage.MyClass" %>
<%
MyClass m = new MyClass();
%>or you could use "useBean" to avoid scriptlets.

Read web.xml from a non-servlet class

Hi all, I need to read the web.xml file fron a standard class in a web project.
I know how to do it from a servlet or a jsp page, but is it possible to do from a non-servlet class?
Thank you,
Gabriele

It's a XML file. So best approach would be to use some Java-XML API to parse the XML file into useable nodes. E.g. JAXP, DOM4J, JXPath, etc.

Obtaining Object List programatically

Hello friends at www.oracle.com,
I need to know if there's a way for me to obtain a form Object List programatically.
I already know I can obtain a list of forms' objects by opening it on Forms Builder and opening File menu, and choosing Administration -> Object List Report. However, I would like to know if there's a parameter to be passed to ifbld60.exe that creates such report, or a PL/SQL instruction that could have the same effect.
Best regards,
Franklin Gonçalves Jr.

Anton-
It's currently a little convoluted, but you can do this:
Class forClass = YourPersistentClass.class;
com.solarmetric.kodo.runtime.PersistenceManagerImpl pmi =
(com.solarmetric.kodo.runtime.PersistenceManagerImpl)pm;
com.solarmetric.kodo.impl.jdbc.JDBCConfiguration config =
(com.solarmetric.kodo.impl.jdbc.JDBCConfiguration)pmi.getConfiguration ();
com.solarmetric.kodo.impl.jdbc.runtime.Connector connector =
new com.solarmetric.kodo.impl.jdbc.runtime.ConfigurationConnector (config);
com.solarmetric.kodo.impl.jdbc.SequenceFactory seq =
config.getSequenceFactory (connector,
com.solarmetric.kodo.meta.ClassMetaData.getInstance (forClass));
// get the next value
long nextValue = seq.getNext (forClass, connector);

appropriate sequenced fields. I am using the Application identity and have
sequence fields for every table. The database is Oracle 8. Here are the

Sorry if I have missed this issue in the documentation but I could not
find such an example.

Get real path in non servlet class

Hi,
I've created a ServletContextListener class that loads a thread at application startup and kills it and application shutdown.
The thread periodically monitors a specific file. I need to pass a real file path to the thread, but because the thread class is not a servlet, I cannot use the getServletContext().getRealPath("").
What are my options?

The ServletContextListener has access to both the ServletContext as well as the Thread.
So the solution can be to get the path in the listener and pass it as a parameter to the constructor or a setter method of the thread.

Obtaining Object Methods

Problem:
I am working with a list of class which are all subclasses of an abstract class.
I have created an object of each method by the following code:
Dent Hor = new Horisontal();
Dent Hin = new Hinged();
Dent I = new Instant();
Dent V = new Vertical();
ClassType ct = new ClassType();
Object p, q, r;
p = ct.makeObject("fa.Instant");
q = ct.makeObject("fa.Horisontal");
r = ct.makeObject("fa.Hinged");
I want to handle each DENT as a DENT, yet each DENT object will know what specific class in the hierachy of DENTs it really belongs to.
Now i when to get the methods in each of the objects.
Does anyone know how this can be done?
Thanks

Here is a bunch of code, origenally based on what you posted above. It only uses Dent and Horizontal for simplicity, it does the printName as you have above, then it calls a bunch of Dent and Horizontal specific methods. I includ my versions of the Dent and Horizontal classes in the same java file, again, just for simplicity...
package fa;
public class Test {
     public Object makeObject(String cn) throws ClassNotFoundException,
                                 InstantiationException,

          return o;
     public static void main(String[] args)
          Test ct = new Test();
          Dent Hor = new Horizontal();
          Dent r = null;
          try
               r = (Dent) ct.makeObject("fa.Horizontal");

               System.exit(1);
          ct.printName(r);
          ct.useMethods(r);
     public void printName(Object o)
          Class c = o.getClass();
          String s = c.getName();
          System.out.println(s);
     public void useMethods(Dent r)
          r.dentMethod0();
          r.dentMethod1();

Accessing ServletContext from non-servlet class

How i can get information servletcontext from a normal java class?
I am using Tomcat.
I have put some Strings in to the servlet context and i want to get this information from a normal java class.
I think there was a way to do it with getServlet() but this is deprecated.

One way to do this would be to store the info in some class of your own as a static member(arraylist/hashmap or something) and then retrieve it from your java class.
May you can populate static field i the init() method of one of your servlet and have that servlet load on tomcat startup.

How to obtain object number using cost center??

hI.
i need to obtain all the cost elemnts of a particular cost center..
cost elemnt can b fetched from COSP using OBJNR..
How do i obtain OBJNR using KOKRS,KOSTL????

Hi
From the table
CSSK
take the related Cost elements for a cost center.
Concatenate the cost element with KS and other Orgn unit
and pass to the Costing tables
see an entry in those tables you will know what are the fields in OBJNR that are concatenated

Obtaining object reference of a loaded class

I want to obtain the reference of any class which is allready loaded dynamically.
I have given a sample code to understand it better...
I am in a serious need of this solution, Plz. have a look.
Thankx in advance.
class FindObjRef
     void find(String obj) throws Exception
          String str1 = new String("Hello!");
          String str2 = new String("World!");
          // Here I want to invoke trim() method (through reflection) on the instance of either str1 or str2 depending what obj parameter contains.
          // I do not want to write a if-else-if statement.
     public static void main(String[] args) throws Exception
          FindObjRef findObj = new FindObjRef();
          findObj.find("str1");
          findObj.find("str2");
}

An alternative solution could be a Map, with the variable names as keys and the values as values.

Servlet, ejb, wls 510, ClassCastException

Hello,
 I have an Entity Bean deployed in WLS 5.1.0.
 I wrote a standalone application that obtains the initial context, does a

 Everything works fine...
 BUT....
 The SAME code within a servlet (doGET) does NOT work and throws a

 Is there any issues using EJBs from Servlets?

Doesn't that mean that you can't hot deploy the EJB now?

Servlet configuration in Weblogic 5.1.. web.xml vs weblogic.properties..

Can someone please tell me how the <servlet> entry differs from
 weblogic.httpd.register.snoop=examples.servlets.SnoopServlet
 in weblogic properties?

Yes this is the source of my confusiong. It seems to be that WL can be told

 I don't understand
 why the second one exists.
