Migrating 9iAS J2EE Applications to 10gAS

Is my 9iAS(9.0.2) J2EE applications can be migrated to 10gAS(10.1.2) without any changes? If no what are the changes required in my applications (Programs).
My Application consists of 9 War files and one DAD(which is pointing to Oracle DB for Some PL/SQL Stuff, i dont think which will cause any compatibility, bcoz we are planing to migrate the Application server only.).
And I am interested on Linux platform.

Error: java.lang.ClassNotFoundException: oracle.reports.jsp.ReportTagExtraInfo
OK, this seems to be a classical usage issue of oracle report. See metalink note 270403.1 or this thread Re: Report Paramter on the Reports, which is, in fact, the right place to post questions and search for answers for reports related problems .
Please tell me if this helps.

SaxParser error when deploying J2EE application on 10gAS for IBM AIX 5.2

Hello,
We have problems deploying J2EE application on 10gAS 9.0.4.0.0, on IBM AIX 5.2. We deployed it on 10gAS for Windows 9.4.0.0 and 9.0.4.0.1, and on 10gAS 9.0.4.0.0 for Linux, without any trouble (installed ADF runtime, etc.).
Application architecture is JSP/Struts/ADF BC4J. We used JHeadstart 10g framework.
As soon as we start the application, we get the message described bellow. We saw that J2SE version, shipped with the AS is 1.4.1? On all the other AS versions, and in embedded JDeveloper OC4J is 1.4.2.
We also use the Xerces library xercesImpl.jar, which is located in .../WEB-INF/lib directory (which contains SaxParser implementation), if that is important. But the application fails right on the beginning.
The complete error message follows:

Figures, I've been fighting with this for the past day and a half and I figure it out shortly after I post the question.
It turns out the tiles.jar that was in our WEB-INF/lib directory was an old one. It looks like the newer struts.jar (from jdeveloper) we're using includes the tiles information. Once I removed tiles.jar, commons-dbcp, pool, resources, and services, it works now.
It looks like jdeveloper overwrites most of those files with it's built in struts integration, and we've just been lucky before that struts.jar was being loaded before tiles.jar and something with oas 10.1.3 is loading the jars in a different order--but I'm just guessing here.

Error while running a J2EE application on Oracle10gAS

Hi,
I am receiving an error when trying to run a J2EE application on Oracle10gAS. The application runs successfully on Oracle9iAS, but throws the following exception on 10g application server:

Hi Somil,
I've just had this same error message, and it was because I had a bogus character in my JSP sources. I'd cut-and-pasted the text from a Word document, and it included the "registered trademark" sign (an R in a circle) as a single character. This worked in my test environment, but not in my production environment (where presumably the default encoding is different). I replaced the character with the equivalent HTML entity &reg; (ie. the five characters & r e g ; ) and it all worked.
Have a look through the offending JSPs and see whether you have any characters that might be incompatible with your default encoding (anything that isn't plain old 7-bit ASCII is potentially a problem). Change them to HTML entities and you should be fine.
Hope this helps,
Richie

J2EE Application works on OC4J standalone but not Oracle 9iAS

I have a J2EE application that works successfully on OC4J 9.0.3, but not when deployed on Oracle 9iAS 9.0.3.
The platform in Win2K
What I am seeing is certain POST requests are sent to the server, call an EJB, update the database, and return a JSP, but sometimes, only half the response is seen by the browser, along with a TCP RST packet, which is why the response is not seen by the browswer.
I think this could be a bug in the Oracle HTTP server. Has anyone seen a similar problem? Are there any solutions, other than throwing away 9iAS and using a different appserver? AFAIK, it is not possible to apply any patches to the Oracle HTTP Server without losing support. Is this correct?

Hi Andrew,
Are there any solutions, other than throwing away 9iAS
and using a different appserver?As far as I know, OC4J stand-alone is a (J2EE compliant) application server, and an officially supported Oracle product. So maybe just throw away "iAS" and use OC4J ;-)
For your information, OC4J can be used with the Apache Web server. Visit the OrionSupport Web site for details.
Good Luck,
Avi.

How to migrate a full J2EE application from WebLogic to NetWeaver?

I have an independent J2EE application which can be run on WebLogic successfully. Now, I want to migrate it to the platform of NetWeaver. Could you tell me how to do with it? And where can I find the jar files of the application I deployed?
Thank you very much!

Have you tried the "exploded" format?
 Also, do you mean Weblogic 6.1 (sp2?).

Hi all,
We are migration a weblogic j2ee application in to sapnetweaver. In web logic, we have config.properties file which contains weblogic related roles, permissions and all configuration related to the application. If we want to use that file in sap netweaver how to configure it.
Can anyone please explain.
Thanks in advance

Hi,
There is no file that contains all this properties you'll need to configure it all with the Visual Administrator.

Porting j2ee application from Weblogic to Oracle 10g AS

What are the common guidelines/consideration when we port a J2EE application on Oracle Application server 10g. from WebLogic 8.1. If you have some inputs on pin points/guidelines/Architecture decisions that we might need to consider when we port a J2EE application on different J2EE application server
I got the link for app server migration but it is broken :
http://www.oracle.com/consulting/technology/appserver_migration_ds.pdf
Our application uses the following J2EE components
1. JDBC 2.0
2. JNDI
3. DAO
4. EJB
5. JMS
6. JAAS
7. JAVA Mails.
8. Servlets, JSP’s
I can think following point that needs to take care while porting
1. Its deployment configuration vis-a-vis the apps on top
2. The APIs it exposes (actually the information it allows the apps to pass in to the framework
3. The data it encapsulates (in order to be app-server agnostic; does it need to be now exposed to apps?)
Some J2EE specific areas
1. JNDI usage and exposure to apps 2. Properties files/XML files
2. Location specification 3. Resource bundle location specification
4. EJB deployment descriptors
5. Class/jar references between wars and ears
6. Jar sharing model across ears
7. Class loader differences across app-servers
8. JMS settings (queues, topics, factories, durability etc)
9. UI tags 10. Startup services
11. Managed services (JMX)
12. Security context passing
13. Clustered configurations if any and how they port across app-servers
Thanks

This document is very old.
Take a look at the recent migration guide in the Oracle AS 10.1.3.1 documentation

Integration in a standard J2EE application

I'm developing a standard J2EE application and I need to interact with a WebCenter Content Server (for example to find files having a specified name).
I don't have any idea on how I can do it, please give me an input.

Use RIDC - see more in the manual: http://docs.oracle.com/cd/E23943_01/doc.1111/e10807/c23_ridc.htm#BJFIHEHI

HELP!!! Cannot deploy J2EE application with Oracle JDBC driver...

Hi,
I am writing a J2EE application which (in theory, at least)
connects to an Oracle 9i database.
I have written a simple Java test app utilising only the
java.sql package classes (e.g. Connection, ResultSet) to directly
connect to the database. As long as the classes12.zip is in the
CLASSPATH it works fine.
Now I have written an Enterprise application (SessionBean,
Remote and Home interface and Client) which I am attempting to
deploy via deploytool.
If I include just the client jar and EJB jar in the application
it deploys okay but when I run the application (using runclient)
it produces the following error:
java.lang.NoClassDefFoundError: oracle/jdbc/OracleDriver
(It is nested within other error output but that is the core
issue).
However if I try to include the JAR libraries into the app
(classes12.jar and nls_charset.jar from $ORACLE_HOME/jdbc/lib),
then I get the following output from deploytool when I hit the
"deploy" (or "redeploy") button:
Deployment error: invalid entry compressed size
(expected 14411 but got 14580 bytes)
Can someone please tell me what is going on???
How can I deploy the J2EE application including the Oracle
JDBC Driver???
My only other option at the moment is to place all the function-
-ality in the client and not use the J2EE framework.
Any help is greatly appreciated.

OK Ben,
I admit I'm a bit confused. Let me see if I understand where you're
coming from.
You have written a J2EE application that includes a session bean,
correct? If so, your session bean needs to be deployed to an EJB
container. What container are you using? The Oracle 9i database
has an embedded EJB container which (theoretically) you can use.
However, as far as I know, Oracle recommends you use OC4J as the
EJB container. So again I ask, what EJB container are you using?
If, as you say, you are new to EJB, then I think you should
immediately start working wiht OC4J as your EJB container.
Did you look at the tutorial link I gave in my previous post? It
explains -- step by step -- how to create, deploy and run a J2EE
application using OC4J as the EJB container. It also has links to
introductory material for people without little knowledge of J2EE
and EJB.
I have 9iAS Enterprise Edition and 8.1.7.1.0 database server (and
OC4J) installed on my SUN machine. I cannot find any of the
utilities you mention -- "j2eeadmin","runclient" or "deploytool".
What Oracle software have you installed? What are the versions?
What platform are you using?
A J2EE application (according to the specification from SUN)
consists of modules. A module can either be a client module or an
EJB module. A client module can either be a java application client
or a web-based client (servlet or JSP). A J2EE application usually
contains one client module and one EJB module. A J2EE application
needs to be deployed to a J2EE container.
Hopefully the J2EE picture is becoming clearer. I think you need
to read some introductory material regarding J2EE if you intend
to become proficient at it.
I feel that you are under the impression that a J2EE application
is a glorified JDBC application. It isn't (as far as I'm aware).
Good Luck,
Avi.

Can i monitor only J2EE Application

Hi All,
Can i monitor only the J2EE application runnning in the application server , like only the application threads , memory used by the application etc.
Durga

You won't lose your data. Simply migrate all your data files ( you can select data, appliations, settings) and just choose the data. Then install FMP and Bento manually and you should be able to pick up where you left off.

SSO to J2EE application from SAP Portal

Hi
I am trying to do SSO from SAP Portal to a J2EE engine which runs on SAP Web AS.
Here are my queries
1. When I deploy a J2EE application on Web AS , I dont get any login screen. How can I make sure that if a user wants to access this J2EE application he should get a login screen and provide his login credentials first, only then would he be able to access the J2EE application.
2.When I am done with Part 1. If a user tries to access this J2EE application from the Portal (asuming the user Id's in Portal and J2EE application are same and both are in the same domain) , I should not get any login screen and should be able to view the J2EE application.
3.I want to use SAP Logon tickets generated by the Portal to enable SSO.
I have done all the necessary configurations in the J2EE server.
1. Imported the Portal's verify.der certificate.
2. Adjusted the login modules stack for the application accordingly.
Can anyone please help me out with this or throw some light.
Please help.
Thanks in advance,
Vivek
PS - Points will be definitely rewarded

Hi Vivek,
Let me give you the solution for both questions differently.
Ques 1. When I deploy a J2EE application on Web AS , I dont get any login screen. How can I make sure that if a user wants to access this J2EE application he should get a login screen and provide his login credentials first, only then would he be able to access the J2EE application.
Ans: For doing this in the code of your J2EE application you have to write a if statement which will check if the user ID is coming from the backend or not. If yes then you display that logon page else you just pass that username which is coming from backend and displ;ay the page accordingly.
Ques 2.When I am done with Part 1. If a user tries to access this J2EE application from the Portal (asuming the user Id's in Portal and J2EE application are same and both are in the same domain) , I should not get any login screen and should be able to view the J2EE application.
Ans: Yes, this is what I am explaining you. Even I had also made same kind of J2EE application in which if the user is coming from the backend then he/she will look the J2EE screen else if the username is not coming then he will se the Login screen. Exactly same as what are looking for.
3.I want to use SAP Logon tickets generated by the Portal to enable SSO.
Ans: I have used User Mapping instead of SAP Logon ticket. Well that is also the option for SSO but personally I think User Mapping is easy and better way for implementing SSO.
I dont know whether this will help you or not. Please let me know. I can definately help if you want to implement SSO using User Maping.

SSO:Portal to J2EE Application

Hi all,
I have developed a simple java application that has user-id & password textboxes along with a submit button.(login.jsp)
this is deployed as an iView in the server.
When the submit button is clicked,it navigates 2 another JSP page(welcome.jsp) that displays the user's name if the id and passowrd matches with that present in the backend DB.
I want 2 display this welcome page directly without prompting for a logon frm the user.
How can i do this with AppIntegrator?I referd the following <a href="https://www.sdn.sap.com/irj/sdn/thread?threadID=95024">thread</a>I cant find the system uri,in the source code of the application!
How should i proceed further?
Thanks in advance.
anticipating replies
SwarnaDeepika

Hi Swarna,
Kindly try these steps..I have accumulated the points as per the discussions on mail.
Just try all these steps..
1) I hope you have created a J2EE application which has its own data source (i.e: tables in the Data Dictionary which has enteries for user and Password).
2) Create a HTTP system for usermapping.
3) After that perform all the steps as mentioned in the WebLog for the App integrator. (i.e: do the user mapping to the system by providing the User name and password.)
4) In the J2EE Application write the code that If that username which you got from the URL and the userName in your data source is same then show him the main page directly, else show him the Login Page.
5) Create a URL View in which you can put your application. Set the admin,user property from the User Management.
I hope all these will solve your problem!! Kinldy check this!!

Pravesh

Unable to connect to the OracleForms application through a J2EE application

Hi there,
I have deployed a custom J2EE application in Middleware instance of my Oracle 10g AS 10.1.2
The application is sso enabled . Once a user logs in the application he is able to see a jsp in which i display hyperlinks for him to access.
One of these hyperlinks is pointing to the forms application.
the url is http://psc-pc0592:7778/forms/frmservlet?config=abs_deploy[b]
Once i click on the URL the forms applet begins to load but as the applet opens up i get the database logon screen.This should not happen
I am already logged and have been verified by sso.
Also the forms configuration is associated with a datasource.
I am not able to get as to why i get that screen when it shoud directly connect to the forms application.
Any help on this is appreciated.
Thanks & Regards,
Madhur Pant

when you go through your carrier provider, there is an additional step in the SSL tunnel. Not sure how this transcribes, but it is possible that your carrier does not use the same port as the one you want it to use.

J2EE application access from Portal - P4ObjectBroker

hey all,
I want to access access a J2EE application (Web Service) from a Portal Component. The documentation at http://help.sap.com/saphelp_nw04/helpdata/en/c0/a584409db95537e10000000a1550b0/content.htm shows an example.
They import the package com.sap.engine.services.rmi_p4.P4ObjectBroker. I cannot find the package on my system, i.e. my local portal installation.
Does anybody know what kind of package is required, or where I can find this package...
many thanks in advance
cheers Sascha

Hey Sascha,
the P4ObjectBroker is part of the implementation of the P4 Provider Service on the J2EE Engine. It is part of the com.sap.engine.services.rmi_p4 package.
If you can't find it I recommend you to search it using ClassLocator, it is a plugin that indexes all your packages and locates the propar class for you.
You can download it at this link: http://sourceforge.net/projects/classlocator
Read the instructions of how to use it with the NWDS, it is really simple. If you need more help do tell me.
