J2EE root application

I want to deploy my web application in the root context. How to do it?

Hi Medha,
First let me explain you the funda of application deployement in SAP WAS. Whenever you deploy a servlet/jsp application it is stored in the sap.com folder in a directory with the application's name(say EmployeeApp). Inside that directory we have another directory with the name of the context path that you choose to give to the application (like "employee") in the application.xml file of the ear project.
For the root context this name is "_default" and it shown as "/" in the Visual Administrator. Once you start the deployement of the application through your NWDS the deployement manager first checks whether another application with similar context path is there or not, if it is not there it will deploy the application successfully otherwise it won't and throw you back an exception. Since by default we have a root application running there in the SAP WAS, you will have to undeploy that application and deploy you application, then your application will get deployed and you will be able to call it through a path like http://localhot:50100/ .
I know the reply is pretty long but hope this will help you
Thanks and regards,
Guru.

Deploying a J2EE web application in Oracle 10g

Hi friends,
 
I had worked with Oracle9i 9.0.3 . But it's my first experience with Oracle 10g . I have installed Oracle 10g Infrastructure , Metadata Repository and one Middle tier - Forms and i hope i have followed The Oracle 10g installation guide Properly. Anyway installation is successful.
The problem is a J2EE web application which is deployed properly on Oracle9i 9.0.3 doesn't get deployed in Oracle 10g. The following is the exception :
 
Deployment failed: Nested exception
Root Cause: deploy failed!: ; nested exception is:
oracle.oc4j.admin.internal.DeployerException: Error initializing ejb-module; Exception Error in application Spom_Apps: Error loading package at file:/C:/Oracle/Ora9iASForms/j2ee/home/applications/Spom_Apps/JmsSubscriberMdb.jar, Error deploying file:/C:/Oracle/Ora9iASForms/j2ee/home/applications/Spom_Apps/JmsSubscriberMdb.jar homes: No location set for Topic resource MessageDrivenBean JmsReceiverMdb
 
 
where JmsReceiverMdb is the deployment file containing the message driven beans.
 
Thanks in advance,
paskal

Hi,
Thanks for responding . I am sending the file contents of ejb-jar.xml, orion-ejb-jar.xml, jms.xml.
Could you also check whether dtds versions of 10g and 9i in these xmls are conflicting? If you can specify your email-id i can send these file as attachments.
Hope you could strike the right spot.

J2ee Web application exploded format in oracle 10g

Hi,
I am trying to develop a simple j2ee application in Exploded Format
in oracle 10g AS. i have created a new OC4J instance called
TestOC4j for this. A .war file works fine in this instance.
I have placed the application under applications directory of TestOC4j.
I have made entries in server.xml, oc4j_mod.conf,
default-web-site.xml,http-web-site.xml and application.xml in META-INF
of the application.
The application get deployed with no errors.gets created in
application-deployments too.
But the url http://server-ipaddress:7778/test_app is not working.
Please help.
The folder struture is as follows:
test_app
--META-INF
-----application.xml
--test_web
-----pages
-------welcome.jsp
-----WEB-INF
-------web.xml
-------lib
-------src
The entries in server.xml is as follows:
<application name="test_app" path="../applications/test_app" auto-start="true" />
<web-site path="./http-web-site.xml" />
The entries in application.xml is as follows :
<module>
<web>
<web-uri>test_web</web-uri>
<context-root>/test_app</context-root>
</web>
</module>
The entries in default-web-site.xml is as follows:

The entries in oc4j_mod.conf is as follows:
Oc4jMount /test_app TestOC4j
Oc4jMount /test_app/* TestOC4j

Roopa, it looks like there is no problem with the deployment of your application in exploded format. Have you accessed http://server-ipaddress:7778/test_app/pages/welcome.jsp? Any problem access http://server-ipaddress:7778/j2ee/, the default home page of the default-web-app ?
When you say the url http://server-ipaddress:7778/test_app is not working, what is the error message if any on the browser, on server console, in the server.log and http-web-access.log of ORACLE_HOME/j2ee/home/log/, ORACLE_HOME/j2ee/home/application-deployments/test_app/application.log?

How a J2EE web application access CR reports stored on the CR Server XI?

Hi,
I'll be working on some crystal report templates that will eventually be hosted/publish on the CR Server XI.
My questions are:
1. How my J2EE web application access those reports?
2. Do my web application uses some CR API for the connectivity and integration?
3. What will happen to the database connectivity of the report template? since the report are created locally.
4. Can the report template be edited/updated on the server?
5. How the CR XI login functionality be involve in the integration (web application ---> CR Server XI)?
6. Is the J2EE web application be deployed on similar web/application server where the CR Server XI resides?
7. What is the role of RAS, Universe, Business View Manager to this whole CR integration?
I hope you can provide some guidance on this journey to Crystal Report world

1) Your application connects via the Java SDK using the appropriate JAR files.
2) It can. You can set the database information at runtime or use the already populated information from Enterprise.
3) Same as 2. Typically when you save the report to Enterprise you set up the database information there so that it runs against the database you want without prompting. You can change this via code to hit whatever equivalent database you want.
4) Yes. You would have to use RAS and the RCAPI to accomplish this via code. You can also make changes in the designer and overwrite the existing report template.
5) You will log in via code. The information on how to do so is in the SDK documentation, which I will link.
6) It can be deployed to the same machine as CR Server, though we recommend against that. Typically you will want to deploy it to a seperate web server and allow it to connect to the CR Server across the network.
7) RAS can be used to run reports, as well as the page server. The universe and business view manager are not directly used in code. If a report runs against a universe or business view then it will use them for data, but you wouldnt do anything with them directly.

You will find the Java SDK information under the BusinessObjects Enterprise SDK section.

Best Practice to use a single root Application Module?

I was reading in another thread that it may be a good idea to have all application modules nested within a single root application module (AM) so that there is only 1 session maintained for the root AM, versus an individual session for each AM. Is this a best practice? If yes, should the root AM be a skeleton AM (minimal customer service methods), or, should you select the most heavily used AM and nest the other AM's underneath of it?
In my case, I currenlty have 2 AM's (and will have 3 AM's in the future) each representing a different set of use cases withn the application (i.e., one supports users searches / shopping cart-like functionality, and the second supports an enrollment process.) It could be the case that a user only accesses pages on the web site to do searches (first AM), or only to do enrollment (2nd AM), or, they may access pages of the site that access both AM's. Right now I have 2 separate AM's that are not nested. Should I nest the AM's and define a root AM?
thanks

Hi javaX
The main physical effect of having 2 separate AMs is that they have their own transactions with the database, and presumably sit in the application module pool as their own instances consuming connections from the connection pool. Alternatively a single root AM with 2 nested AMs share a single transaction through the root AM; only the root AM controls the transaction in this scenario.
As such it's a question of do you need separate transactions or will one suffice?
How you group your EOs/VOs etc within the AMs is up to you, but usually falls into logical groups such as you have done. If a single transaction is fine, instead of creating multiple AMs, you could instead just create logical package structures instead. Neither method is right or wrong, they're just different ways of structuring your application.
When you create a nested AM structure, within your ViewController project in the Data Control Palette you'll actually see 3 data controls mapped to each AM. In addition expanding the root AM data control, you'll see the nested AMs again. Create a dummy project with a nested AM structure and you'll see what I mean.
If you base your page definitions on anything from the root AM and it's children in the Data Control Palette, this will work on the root AM's transaction.
If you base your page definitions on something from one of the other AM data controls that isn't inside the main root AM in the Data Control Palette, instead of using the root AM's transaction, the separate child AM will be treated as root AM and will have its own transaction.
The thing to care of when developing web pages is to consistently use the AM and it's nested AMs, or the child AMs directly with their separate transactions, otherwise it might cause a bit of a nightmare debugging situation later on when the same application is locking and blocking on the same records from 2 separate AM transactions.
Hope this helps.

Get URL for J2EE client application

Please forgive me if this question has an obvious answer, but I can't see it.
Once Web Start has downloaded and started my J2EE Swing application client, how can my client get the name of the host (or entire URL) from which the client was downloaded?
I would rather not have to hard code this into my client, so that the WAR file I deploy to the server is platform independent.
bobj5000

Use the JNLP BasicSevice API getCodeBase() to get the URL of the server.
BasicService bs = (BasicService)ServiceManager.lookup("javax.jnlp.BasicService");
URL url = bs.getCodeBase();
Hope this helps

Oracle forms to j2ee/web application

Hello all,
I need help with converting "oracle forms" to j2ee/web application. There are only 2-3 forms. But I needed to know how to do it from scratch. I looked at some softwares available to do it. But its costly.
Basically the company I am working with, needed all the forms online, so that they can access it using a browser. As part of the development, I am using jdeveloper 10g.
could some help me out
Thanks a lot
san

Well if you need your Forms accesible from a browser you don't need to convert them to Java - you just use Forms on the Web - http://otn.oracle.com/formsupgrade
If you still want to convert to Java have a look at the Forms page for more info:
http://otn.oracle.com/products/forms
and also here:

Root Application Module connecting to 2 databases technologies

I have an application which needs to connect to 2 different databases.
I managed to get access to each databases in their own respective Application Modules.
In order to achieve that, I created a new ViewObject within the "oracle" model, and still used the "MySQL" query. Using the jbo.envinfoprovider property, I can force the Application module to connect to the appropriate database, MySQL in this case.
Now, my problem is that I need to have a Root application module that will use BOTH "child" application module and eventually BOTH database connections. At the moment, I can only use one at a time. Using the jbo.envinfoprovider property of the ROOT application module allows me to select which of the 2 database I want to use, but I need both.
To put it in a tree-like structure, here's what I want to achieve :
ROOT (Oracle + MySQL)
|
|__ AppModule1 (Oracle)
| |
| |__ View1
| |__ View2
|
|__ AppModule2 (MySQL)
|
|_ View3

What I mean is if I deploy the application on the integrated weblogic server, using the default navigation flow defined in the adfc-config.xml file, when I reach the "forensic" page, it will try to "read" from both database and fail at reading the second database.
The page displays the following :
1- a table containing the records from the Oracle database (3 columns=> ID, pattern, solution)
2- an adf_form used to populate the above table :
- the ID is bound to a database trigger, so is set to readonly
- the solution is a text input field
- the Pattern is a LoV, based on the data found on the MySQL database.
If I test the page from the "forensic.jspx" itself (by right-clicking and selecting "Run"), I can manage the data just fine (I can do any CRUD operations I want)
on the other hand, if I go to the "adfc-config.xml" file and (right-click and then select "Run"), the page will only read one of the two database (I can control which one, by changing the jbo.envinfoprovider property of my application module)
Hope this helps understand what I am trying to achieve.
Thanks !

Painting one root Application Module to rule them all

hi
The description below uses the same MyApplicationModuleListener approach as I describe in the forum thread "painting a picture of Application Module pooling".
Another example review of Application Module pools behaviour is the blog post by Chris Muir, "JDev 11g, Task Flows & ADF BC – one root Application Module to rule them all?".
That post also says "... we'll have trouble discerning what the ADF BC layer is actually doing underneath the task flow transaction options. ...", where the approach below might help alleviate some of that discerning trouble.
And about "... By deduction as there are no other log entries, this second instance of Root1AppModule must be nested under the root Root1AppModule? ..." more information will be logged, so less deduction is required.
The blog post describes an application similar to this one (which is using the HR.EMPLOYEES table) created using JDeveloper 11.1.1.6.0
at http://www.consideringred.com/files/oracle/2012/OneSizeOneRootAMApp-v0.01.zip
It uses somewhat different names than the blog post, and it has two sets of task-flows so that no transaction configuration changes are required to review the behaviour.
When a MyApplicationModuleListener approach is introduced (with minor changes, mostly configuration, using JAR files available in MyApplicationModuleListenerApp-v0.03.zip) it results in the application available
at http://www.consideringred.com/files/oracle/2012/OneSizeOneRootAMApp-v0.02.zip
Using this, the (chained) "No Controller Transaction" scenario's result in similar logging like this:

Suggestions to improve such MyApplicationModuleListener approach (or an alternative approach) are welcome.

Some additional features were added in the JAR files available
in http://www.consideringred.com/files/oracle/2013/MyApplicationModuleListenerApp-v0.05.zip
Like line numbers, or a queryOneRecord() method to support logging the database session SID, or a TaskFlowInfoHelper class to allow logging task-flow transaction options or DataControlFrame information.
If these JAR files are used, it results in the modified example application
at http://www.consideringred.com/files/oracle/2013/OneSizeOneRootAMApp-v0.03.zip
For the same scenarios (using OneSizeOneRootAMApp-v0.03.zip), the resulting logging can be found in these files:

Notice the transaction type and DataControl scope information per task-flow.
Notice the different database session SID values ("[0058](am501) SID = 41" and "[0061](am502) SID = 27") during the same request [r1005].

Notice that nested Application Module instances are created, resulting in one database session SID value per request.

Notice that two root Application Module instances are used in the same request (and no nested instances), and both (am501) and (am502) report using the same database session SID value. That seems to be "Bruce" [1] at work.
Remember, it should not be difficult (and not intrusive) to configure similar logging for other ADF applications.

Help:How can I run the J2EE Client Application? Thanks

Help:How can I run the J2EE Client Application that will access the remote J2EE1.4 application server which runs on another host computer?
I have developped a stateles senterprise java bean name converter and deloyed it in the j2ee1.4 application server on the host machine A. The converterbean provides the remote home interface and remote interface. At the same time I have developped the j2ee application client named convertappclient. When I access the conveter bean at host computer A through the script 'appclient.bat' as 'appclient -client convertappclient.jar', the client can access the bean sucessfully. Now I want to access the bean through the script 'appclient.bat' at host computer B,what files should I copy from host computer A to host computer B;and what the command line should be like? Thanks!
The following are the code of the enterprise java bean and it's home interface .
The client code is also provided.
The enterprise java bean:
package converter;
import java.rmi.RemoteException;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
import java.math.*;
public class ConverterBean implements SessionBean {
BigDecimal yenRate = new BigDecimal("121.6000");
BigDecimal euroRate = new BigDecimal("0.0077");
public ConverterBean() {
public BigDecimal dollarToYen(BigDecimal dollars) {
BigDecimal result = dollars.multiply(yenRate);
return result.setScale(2, BigDecimal.ROUND_UP);
public BigDecimal yenToEuro(BigDecimal yen) {
BigDecimal result = yen.multiply(euroRate);
return result.setScale(2, BigDecimal.ROUND_UP);
public void ejbCreate() {
public void ejbRemove() {
public void ejbActivate() {
public void ejbPassivate() {
public void setSessionContext(SessionContext sc) {
The bean's remote home interface :
package converter;
import java.rmi.RemoteException;
import javax.ejb.CreateException;
import javax.ejb.EJBHome;
public interface ConverterHome extends EJBHome {
Converter create() throws RemoteException, CreateException;
The bean's remote interface:
package converter;
import javax.ejb.EJBObject;
import java.rmi.RemoteException;
import java.math.*;
public interface Converter extends EJBObject {
public BigDecimal dollarToYen(BigDecimal dollars) throws RemoteException;
public BigDecimal yenToEuro(BigDecimal yen) throws RemoteException;
The j2ee application client:
import converter.Converter;
import converter.ConverterHome;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import java.math.BigDecimal;
public class ConverterClient {
public static void main(String[] args) {
try {
Context initial = new InitialContext();
System.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
System.setProperty("java.naming.provider.url","jnp://10.144.97.250:3700");
Context myEnv = (Context) initial.lookup("java:comp/env");
Object objref = myEnv.lookup("ejb/SimpleConverter");
ConverterHome home =
(ConverterHome) PortableRemoteObject.narrow(objref,
ConverterHome.class);
Converter currencyConverter = home.create();
BigDecimal param = new BigDecimal("100.00");
BigDecimal amount = currencyConverter.dollarToYen(param);
System.out.println(amount);
amount = currencyConverter.yenToEuro(param);
System.out.println(amount);
System.exit(0);
} catch (Exception ex) {
System.err.println("Caught an unexpected exception!");
ex.printStackTrace();
}

Surprisingly I find an upsurge in the number of posts with this same problem. I recently found a post which gave a nice link for this. Follow the steps and it should help:

Deploying BC4J as J2EE compliant applications

Hi.
I've been looking over the threads concerning deployment of BC4J applications into oc4j.
Maybe I have missed the concept of bc4j, but doesn't bc4j act as 'just another runtime library' and be deployed as a standard J2EE library, i.e:
war-file->
/WEB-INF/classes/<all the java-classes, including bc4j packages>
/WEB-INF/web.xml
/WEB-INF/lib/<bc4j runtime libraries>
/<jsp,html,images etc.>
It seems to me that BC4J is not really adapted to a J2EE environment. For example, local file access from an EJB application is a big no-no in the specs.
Is there any plans for a rewrite of bc4j to make it more 'J2EE-compliant'?
Best Regards /Anders

You could deploy the BC4J archives along with each and every WAR file if you want, but this is kind of a waste. Instead, you typically deploy them in the global library directory of your container.
BC4J reads resources from the application context for things like metadata files. Have you found this issue to stop you from successfully running BC4J applications as J2EE EJB Session Beans?
Remember the J2EE includes both Servlets and EJB's. Some customers shy away from the additional complexity of EJB's and build J2EE-compliant applications that work entirely in the J2EE "Web Tier" without using the "J2EE EJB Tier" as well.
BC4J-powered J2EE applications support deploying application components either to the J2EE Web Tier or to the J2EE EJB Tier without requiring code changes.

Root Application Module

i understand that we can't extend and substitute the root application module for a page. However, I am not sure how to tell if the AM I am working with is a root AM, actually I am not sure what a root AM is either. I tried extending PsrAM which is under oracle.apps.ap.payments.psr.server. It is the AM that is referred to from PsrPG.xml.
So how do I tell if this is the root AM?
Thanks for any help you can give!
Dennis

Dennis
In addition to what chandra mentioned. Your saying that root AM cant be extended is not 100% correct
i understand that we can't extend and substitute the root application module for a pageWe can extend root AM as well provided that page doesnot have any LOV in it.
However as a workaround you can create a custom Application Module in Jdev and add it to page with the help of StackLayout Region.
Thanks

J2EE PetStore Application -- RDBMSException when starting server

Folks,
I'm trying to install Sun's J2EE PetStore application using the instructions at: http://developer.java.sun.com/developer/technicalArticles/Programming/deployathon2/BEAreadme.html#dlapp
When I attempt to start the WebLogic server using the "startPetStore.cmd" file, I receive the exception below. Has anyone got any helpful advice to offer?
Thanks,

I had the same problem. I ran this as a batch file to update the petStoreDB and it worked thereafter.
java -classpath c:\weblogic\eval\cloudscape\lib\cloudscape.jar;C:\jdk1.2.2;c:\weblogic\weblogic510sp3.jar;c:\weblogic\classes;c:\weblogic\lib\weblogicaux.jar;c:\weblogic\license;c:\weblogic\myserver\clientclasses; utils.Schema jdbc:cloudscape:petStoreDB;create=true COM.cloudscape.core.JDBCDriver -verbose c:\weblogic\petstore\WLSrc\db\petStore.ddl

I got the same problem before, and it's fixed by update new Schema.
use utils.Schema to update the petStoreDB with <petstore>\WLSrc\db\petstore.ddl
with Regrads.

Consume Portal Service from J2EE web application

hi, i am a newbie to portal content development. My team have developed a J2EE web application to be run on the portal. Is it possible to consume a Portal Service from J2EE web application? If possible, deeply appreciate if you could provide some guidelines. Kindly advise. Thanks.

Hi Theodore Yu,
You need to expose your portal service as a webservice to consume it in a j2ee web application.
For exposing a portal service to webservice check this link
