Oracle and J2EE EJB

Hi all,
I am novice in the develpment of applications using EJB's. I have created the table and inserted the records in the oracle database using the J2EE where by the J2EE creates the table autometically. The application is working fine. But my main concern is that I am not able to access any records of this table when I give "select * from SportscarBeanTable" querry in the sql prompt of the oracle for which I get "no such table". But if I give the querry "Select table_name from user_tables", the table created by me is displayed. Can anybody clarify my doubt. Any help will be greatly appreciated.

Hi,
Yes it is listing the table. The table is created by the J2EE server in the oracle database. Can u please specify the schema under which the J2EE server creates the tables in the oracle database.
Thank you,
deepak

Using J2EE EJB Container and Oracle 8.1.7

I am trying to setup the J2EE EJB container to use and Oracle 8.1.7 database instead of Cloudscape. So far I have done the following
0. Created the table for the Savings Account tutorial in the Oracle Database.
1. Added the Classes12.jar (Oracle's latest JDBC thin drivers) to my CLASSPATH
2. Under "Server Configuration" I added the standard/jdbc drivers value: "oracle.jdbc.driver.OracleDriver".
3. Under "Server Configuration" I added the standard/datasource value: JNDI name "jdbc/Oracle" and JDBC URL "jdbc:oracle:thin:@10.1.1.254:1521:DEV".
4. For the savings account tutorial, when deploying I specified "jdbc/Oracle" for the reference "jdbc/SavingsAccountDB".
I have gotten this tutorial to work using the Cloudscape database. After I did the previous steps and tried to run the client, I get no valid driver available, unable to connect to Oracle.
What else to I need to do?
My setup is:
Windows 2000 Professional
J2EE (JDK 1.3.1)
Oracle 8.1.7
Thank you in advance.

Exactly which classpath did you add the Oracle JDBC library jar to ?
The thing that works for me is to have the following line in the file %J2EE_HOME%\bin\userconfig.bat
set J2EE_CLASSPATH=D:\DownLoad\Oracle\classes12_01.zip;

How to build and deploy ejb in j2ee!!

HI there!!
Newbie Question. I know this is very rude to ask a question "How to build and deploy ejb in j2ee server??", but please help me. I just learned some servlets worked with tomcat. Now I want to learn more about ejb, could anyone suggest me any online tutorial or book where in it is explained step by step builiding and deploying ejb's in j2ee server, please help me. I would be grateful to you.

A good book to start with is Enterprise JavaBeans by Monson-Haefel (O'Reilly press). It covers deployment of EJBs on J2EE servers. Also check out sites specific to your server, sometimes they have specific requirements (like Weblogic).

ERROR J2EE EJB-03027 with OC4J 10.1.3.3

Hi,
we have an application that works fine in iAS 9i (9.0.3).
Now, we have to migrate the platform to 10G and we are testing with OC4J 10.1.3.3.
But when the OC4J works... we see this message:

We have looked for information about the 'Bad version number' error, and we have recompile all our code with the JDK 1.5 (the same JDK for the OC4J). But we still have the error...
Which may be the problem?...
Thanks.

The only thing you can do is to make sure that you recompile everything you're using.

Ejb-jar.xml and orion-ejb-jar.xml configuration issue

Chris,
We have an application that uses the Oracle 10g Application Server and WebSphere MQ v5.3 w/ fixpack 9.
Our application is a J2EE messaging system which essentially consists of Message Driven Beans, the EJB
realization of the J2EE Java Message Service (JMS) API. Our application has Message Driven Beans which
listen to queues and send messages to queues -- a simple messaging system. Currently we can listen to queues, but
cannot send messages to queues in the Oracle 10g Application Server environment.
Any J2EE application server has its own implementation of Java Naming Directory Interface (JNDI) API that
deployed J2EE applications utilize to lookup resources such as Data Sources, JMS Destinations (i.e. MQ Queue),
JMS QueueConnectionFactories (i.e. MQ QManagers).
Our application uses the 3rd party JMS Provider, WebSphere MQ.
MQ ships with a JMSAdmin tool which allows one to create JMS administered objects (i.e. objects a java
application searches for in some JNDI directory) that reside in some JNDI context. We create a JNDI context for
MQ resources, queues and QManagers. We configure the MQ provided
JMSAdmin tool with two property name/value pairs:
PROVIDER_URL=file:/opt/mqm/JNDI-Directory
INITIAL_CONTEXT_FACTORY=com.sun.jndi.fscontext.RefFSContextFactory
A resultant .bindings file is created in /opt/mqm/JNDI-Directory which represents our JDNI context
containing our JMS administered objects. A standalone java application that needs to directly access this
JNDI context can simply conduct a JNDI lookup on the following context: "java:comp/resource/MQSeries/". An
example of how a standalone application would lookup a JMS administered object named "qNumber1" would be to
lookup "java:comp/resource/MQSeries/qNumber1". This lookup would result in the standalone java application
having a JMS reference to an MQ Queue.
There is a major difference in how an enterprise EJB application deployed into a J2EE Container (Oracle 10g App Server)
conducts a JNDI lookup on a 3rd party resource such as MQ as a JMS Provider. A typical EJB application deployed
into a J2EE container as an .ear (enterprise archive) file has implicit access to the application server's own
JNDI context. This JNDI context is usually "java:comp/env/". Looking up the Application Server's own Data Source or
it's own JMS Resources is easy. An application that needs references to these Application Server provided resources
simply conducts a lookup for "java:comp/env/jms/someQ" or "java:comp/env/jdbc/myDataSource".
The problem we face is mapping our MQ JNDI context to the Oracle App Server's own JNDI context. We believe this is
accomplished through mappings defined in both the ejb-jar.xml (EJB Descriptor) and the application server specific
counterpart, orion-ejb-jar.xml. Note that Oracle 10g Application Server uses the popular orion J2EE container for
hosting J2EE enterpise applications.
Our Message Driven Beans (MDBs)currently listen to the Queue at the JNDI location "prodQ". Our problem is that we cannot
get our MDB to send messages to any queues. Note that the MQ implementation of the queues and Queue Managers work
flawlessly with standalone java applications. It's safe to say that the MQ objects are working.
We are looking for a solid example of how the ejb-jar.xml and the orion-ejb-jar.xml map 3rd party JMS provider
JNDI locations to the App Server's JNDI context.
Below is how we have attempted to configure our own ejb-jar.xml and orion-ejb-jar.xml:

If you look at the contents of a deployment plan (Plan.xml) when you have it generated
<deployment-plan ...>
<module-override>
    <module-name>ejb.jar</module-name>
    <module-type>ejb</module-type>
    <module-descriptor external="true">
      <root-element>weblogic-ejb-jar</root-element>

    <module-descriptor external="false">
      <root-element>persistence</root-element>
      <uri>META-INF/persistence.xml</uri>
    </module-descriptor>
</module-override>
</deployment-plan>You can see which files can be external and which can be not. The weblogic-ejb-jar.xml can be external
but in this case you need a deployment plan to point weblogic to the file. The ejb-jar.xml cannot be
external (see external=false)
The benefit of storing the weblogic-ejb-jar.xml is that your administrator can fine tune certain
configurations by using a deployment plan, instead of having to extract the contents from the jar file
and then repackage it again.
No need to worry about a clustered environment, you can place the jar and the deployment plan
on the server where the admin server is located, when you deploy an application you deploy it to
the cluster and everything is taken care off.

Hi,
Thanks for the reply since I am quite new to BPEl can you elaborate a bit on this .
What I did was
1. I created a Async BPEL process in JDeveloper and in the same project I put my servlet code and html part when I deploy it on the server and ascess it the welcome jsp is displayed when I click submit on wecome.jsp it forwards to servlet and there the error originates .
2 If instead I deploy the BPEl process seperately and the try to access the BPEL process using my JDeveloper java code I don't get any error it works fine.
3 I have included config and schema folders in source path . wf_client_config.xml,user-properties.xml and wf-config.xml is also present in the source folder.
4 Along with this the jars needed have been also added.
So when I deploy the BPEL process created in 1 above from Jdeveloper it creates a .ear in j2ee\home\applications and the deploys it .This .ear doesn't has any .class files .
I take bpelclasses.jar from the .jar which is created when I compile the project and put it in the j2ee\home\applib folder and made an entry for it in the server.xml file.After this it is able to get .class files.
If there is any alternate way to do the same thing kindly tell me .
Thanks

Matrix for jdk version and j2ee version.

Recently, I started working on web application.
I downloaded eclipse etc and now i am totally confused b/w various j2ee + jdk versions.
I want to develop application in jdk1.4, and j2ee v1.4
So how j2ee 1.4 version is related jdk version? Eclipse is giving me so many options to select for version compatibility.
Isn't j2ee api is based on jdk 1.4?
Where i can find version matrix for servlet specs + ejb specs for j2ee v1.4?

Bottleneck Between Oracle and Application Server

I am connecting Tomcat to Oracle thru thin JDBC driver. The link between tomcat & oracle is now found to be the bottleneck - too many JDBC calls that could be handled by the network. What are the possible solutions I can use now?
Some suggest to use Oracle Real Application Cluster (RAC) to scale the db tier. I am new to this. Would setting up RAC causes any change to my programs? Is it difficult to setup? Also, are there any other alternatives?

Web servers just handle static content, like HTML pages.
App servers have a few flavors.
A servlet/JSP engine has a Web server built into it, too. It can handle static content, like HTML pages, and also act as a container for servlets and JSPs. You can use JDBC with servlets and JSPs, of course.
A J2EE app server has a servlet/JSP engine and a Web server built into it. It can handle static content, like HTML pages and act as a container for servlets and JSPs. But it can also act as a container for EJBs - session, entity, and message EJBs. It has other services built in, like Java Messaging Service (queues), Java IDL (Corba), RMI, JNDI (naming services), XML parsers, JDBC (database access), and Java Transaction Service.
Enterprise Application Integration servers (EAI), like WebMethods, using XML messaging to tie multiple J2EE app servers together.
It's like those Russian dolls, where smaller ones fit inside larger ones. It's a hierarchy. - MOD

How do I use the J2EE EJB container with the FULL version of Tomcat

The version of Tomcat integrated in J2EE is really cut-down. I want to be able to run the standard Tomcat 4.0.1 to give the full JSP facilities, but I also want to be able to use EJBs from the J2EE.
If I copy the j2ee.jar, j2ee-ri-svc.jar and home interface to the "lib" directory they do not appear to be loaded, as I cannot resolve the javax.ejb.EJBHome.class.
If I copy the same library into the application's WEB-INF/lib directory then the naming jaxax.naming.InitialContext gives a context without the java:/comp/env entries.
I do not want to use another EJB contrainer after having got used to deploying apps with J2EE.
If anyone can help I would be greatful, and post a thanks message with duke dollars!

I have done it before and basically it is not that difficult, but in practice not that easy ;-)
All you need to do is see Tomcat as a client to the EJBs. This means deploying the application in two parts: the webapp as a WAR to Tomcat 4.0.1, and the EJBs to J2EE. Both running and started independantly.
This ofcourse means that the WAR file must have the stubs of the EJBs to be able to communicate and access to j2ee.jar to get the InitialContext.
So:
- compile the EJBs
- create the EAR (containing only EJBs)
- deploy the EAR
- copy the stubs to the libs directory of the webapp
- compile the webapp
- create the WAR
- deploy the WAR
Off you go.

JWSDP and J2EE Integration: Doesn't work. What's the point?

My problems involve the integration of JWSDP and J2EE as described in these two documents:
http://developer.java.sun.com/developer/technicalArticles/WebServices/wsj2ee/
http://java.sun.com/j2ee/documentation/windows_guide.html
It looks like a long one, but it�s really not that bad. All comments are appreciated.
I�ve numbered each line-paragraph-section for easy reference later.
(1) My ultimate goal is to setup a website that displays data from a database. I will use Java, Apache, Oracle, and whatever else I need to create a website that uses servlets, JavaServer Pages (JSP), and JDBC.
(2) I�ve got four Pentium III computers:
1. Windows 2000 Server to be the web server (MyWebServer, IP = 10.10.1.1).
2. Windows 2000 Professional to be the database server (MyDatabaseServer, IP = 10.10.1.2).
3. Windows 2000 Professional that I use to develop and test (MyDeveloperPC, IP = 10.10.1.3).
4. Windows 2000 Professional that I use as a client to connect to the website (MyClientPC, IP = 10.10.1.4).
(3) On MyWebServer I installed the following:
Java 2 Standard Edition (J2SE)
Java 2 Enterprise Edition (J2EE)
Java Web Services Developer Pack (JWSDP)
The JWSDP tutorial
Apache HTTP Server
(4) The files I downloaded and installed are as follows:
j2sdk-1_4_0-rc-win.exe
j2sdkee-1_3_1-win.exe
jwsdp-1_0-ea1-win.exe
jwsdp-1_0-ea1_01-tutorial.zip
apache_1.3.23-win32-x86-no_src.exe
(5) After installing these products, I set the environment variables as follows:
JAVA_HOME = c:\j2se
J2EE_HOME = c:\j2ee
JWSDP_HOME = c:\jwsdp
Path = c:\j2se\bin;c:\j2ee\bin;c:\jwsdp\bin; [and other previous statements]
(6) I checked to see that Apache is running as a service. It is.
On MyWebServer I start Tomcat and J2EE. Both start properly and are operating simultaneously.
(7) From MyClientPC I open Internet Explorer and in the address box I type:
http://10.10.1.1
This displays the page c:\ApacheHTTP\apache\htdocs\index.html.en (The Apache default server installation page.)
(8) I then enter this address in IE:
http://10.10.1.1:8080
This displays the page c:\jwsdp\webapps\root\index.html (The default JWSDP page).
(9) I then enter this address in IE:
http://10.10.1.1:8000
This displays the page c:\j2ee\public_html\index.html (The J2EE 1.3 Default Home Page).
(10) So far so good. Now I want to test JWSDP as a container for JSP pages.
(11) I use ant to build the converter app found in the tutorial examples (in folder c:\jwsdp\�\tutorial\examples\gs). I then deploy the converter app to the c:\jwsdp\webapps\gs folder.
(12) From MyClientPC I open Internet Explorer and in the address box I type:
http://10.10.1.1:8080/gs
The converter app works perfectly.
(13) To eliminate the need to enter the port number, I create a link from the Apache default server installation page to the converter app. From MyClientPC and enter this address into IE:
http://10.10.1.1
I then click on the link to the converter app and it works perfectly.
(14) Question: Is this the best way to display JSP pages without having to enter the port number?
(15) Now it�s time to integrate JWSDP and J2EE as described in these two documents:
http://developer.java.sun.com/developer/technicalArticles/WebServices/wsj2ee/
http://java.sun.com/j2ee/documentation/windows_guide.html
(16) After I complete this integration I cannot start both Tomcat and J2EE at the same time. This makes sense because they both share port 8080.
I start Tomcat.
(17) From MyClientPC and use Internet Explorer to test the various relevant addresses. Everything works the same as it did before except this one:
http://10.10.1.1:8000
The page cannot be displayed. The J2EE default home page is not displayed, which makes sense because the J2EE port is no longer 8000; it has been changed to 8080.
(18) Now I shutdown Tomcat and start J2EE.
From MyClientPC and use Internet Explorer to test the various relevant addresses:
(19) http://10.10.1.1:8080
Displays the JWSDP default home page.
(20) http://10.10.1.1:8080/gs
The page cannot be displayed. The converter app no longer works.
(21) From MyWebServer and use Internet Explorer to test localhost:
http://localhost:8080
This displays the J2EE default home page.
(22) Question: Why does localhost give me a different page than the IP address?
(23) Question: What was the point of integrating JWSDP and J2EE?
(24) I want to get the converter app working, so I create a .war file and attempt to add it to the J2EE deploytool (see the two integration documents listed above at section 15.) I create the .war file following the instructions in the JWSDP tutorial:
http://java.sun.com/webservices/docs/ea1/tutorial/doc/WebApp3.html#64606
(25) I change to the c:\jwsdp\�\tutorial\examples\gs\build folder.
I then type:
jar cvf converter.war .
A .war file is created.
(26) I open the deploytool: File, New, Application, and I name it �converter�.
I attempt to add the .war file: File, Add to Application, Web WAR.
(27) When I attempt to add the converter.war file I get this error:
�converter.war does not appear to be a valid web JAR.�
I tried a few different attempts, all with the same result. I�m stuck.
(28) I ask again, What was the point of integrating JWSDP and J2EE?
(29) If this is the preferred configuration, how do I display my JSP pages like the converter app?
Please help!!!

The JWSDP tutorial says to be in the �build� folder of the example when issuing the jar command to create the .war file. The build folder is created when I run the �ant build� command.
Attempt 1 from the command prompt in folder c:\jwsdp\tutorial\examples\gs\build>
I typed this command:
jar cvf c:\jaxmservices\converter.war .
In this case I directed the .war file to be placed in a different folder as you suggested. Here�s the output:
added manifest
adding: index.jsp(in = 921) (out= 525)(deflated 42%)
adding: WEB-INF/(in = 0) (out= 0)(stored 0%)
adding: WEB-INF/classes/(in = 0) (out= 0)(stored 0%)
adding: WEB-INF/classes/Converter.class(in = 582) (out= 358)(deflated 38%)
Didn�t work. Same error as before.
Attempt 2 from the same folder:
I typed this command as you suggested (I tried it with and without the final dot):
jar tvf converter.war
Here is the output:
java.io.FileNotFoundException: converter.war (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(FileInputStream.java:103)
at java.io.FileInputStream.<init>(FileInputStream.java:66)
at sun.tools.jar.Main.run(Main.java:185)
at sun.tools.jar.Main.main(Main.java:904)
I tried a few other variations on these attempts with no luck. I�m stuck.
I�m attempting to create a .war file out of two files: index.jsp and converter.class.
Now that I�ve integrated JWSDP and J2EE, is there some other way that I can run the converter app instead of a .war file and the deploytool? In other words, if I go back to using ant to build and deploy converter, where would I deploy it so that it will work with J2EE?
By the way, it doesn�t have to be converter. I�d be happy if I could get any JSP page to work in J2EE after the integration.
Forever grateful,
Logan

How to deploy and run EJB in eclipse without XDoclet

Hi Friends
I am new in j2ee.In my academic project i want to do some ejb programming.
For that purpose i want to write some ejb's.I have written all required class for ejb,created ejb-jar.xml file manually,weblogic .xml file manually. I am using weblogic8 as an server for deployment.
I know deployment with xdoclet but i want to know hoe to deploy ejb without xdoclet.
If u have saple code or useful link regarding this please send it as soon as possible.
Thanks in advance
How to deploy and run EJB in eclipse without XDoclet

HI Welcome to J2ee...
I am also new to this...But i ll share my ideas with you...
In EJB 3.0 No need of any Deployment Descriptors....
And If you are using Eclipse You can Deploy(as jar) using Export in File tab...
XDoclet is not mandatory...

Connect swing and J2EE

In WEB Application i used JSP, Struts and J2EE.
But Now use swing application, and something for joing swing and j2ee
Somebody knows something...
I need your help....

In WEB Application i used JSP, Struts and J2EE.
But Now use swing application, and something for joing
swing and j2ee
hopefully, no business logic is in struts; only the application logic (i.e. order of screens, input type validation, etc.). If this is the case you have many options:
- direct calls to the ejb (assuming you have a service defined as an EJB)
- SOAP, SOAP-RPC, or a full web-service (as mentioned above)
- your own custom protocol over HTTP
- RMI (probably too much work; easier to just make direct EJB calls)
- JMS (probably more work than just using SOAP or HTTP)
- Socket based communication with your own custom protocol
Probably the fastest to get going is direct calls from swing to the EJB.
You'll have to re-implement your application logic; but this is fine as the swing app will probably have a different flow than the web-app.
Best of luck,
Andrew

Differences between J2EE 1.3 and J2EE 1.4

Hello community,
we want to know the main differences between these j2ee-versions for our project at the university. We should implement new advantages of 1.4 in our old program which was developed for j2ee 1.3.
Possible topics could be e.g.: improofed security, faster runtime or decreasing complexity / difficulty in coding.
Maybe you can help us.
Greetings from Germany.
PS: The project we started with j2ee 1.3 was a server/client programm
using a webclient JSP + SessionBean + EntityBean + database

Please follow this link to find out what is new in J2EE 1.4: http://java.sun.com/developer/technicalArticles/J2EE/new1_4/
By the way, the next version Java EE 5 is out which adds a number of things to J2EE1.4. The main theme of Java EE 5 has been "ease of development". Please follow the link to find out what is new in Java EE 5.0: http://java.sun.com/javaee/overview/whatsnew.jsp
Since you are using EJBs, for your convenience I have listed below that new changes to EJB 3.0:
1. Session beans need not have home and component interfaces
2. Session beans need not implement the implement the javax.ejb.EnterpriseBean interfaces.
3. Simplification of APIs for access to a bean's environment: definition of a dependency injection facility and simpler look-up APIs.
4. Introduction of Java metadata annotations to be used as an alternative to deployment descriptors. This means that there is no need for creating ejb-jar.xml and sun-ejb-jar.xml
5. Simplification of object persistence by the definition of a light-weight object/relational mapping facility based on the direct use of Java classes rather than persistent components.
