Urgent OC4J Application Problem

Hi,
I am deploying application (with only JSP & servlets --> .war) in Oracle 9iAS with OC4J container(2.0.0.0) in Win 2000 Server.
Considering the classloader mechanism of OC4J (I read through this forum and throught this link http://kb.atlassian.com/content/atlassian/howto/classloaders.jsp). This is causing problems. Particularly in my case, where I want that specific classes should actually be loaded from my application and NOT from parent loaders.
I am encountering the following problems when I run the application using command: (java -jar oc4j.jar)
1) Classes in "soap.jar" contained in my application WEB-INF/lib directory clashes with those present in "JD-OC4J\soap\lib" (where JD-OC4J is my Installed location for OC4j container). Hence running my soap application gives error like this
java.lang.NoClassDefFoundError: HTTPClient/CookiePolicyHandler
     at org.apache.soap.rpc.Call.invoke(Call.java:213)

-- This would run in case "soap.jar" is used from my Application lib directory(present in /../j2ee/home/applications/myapp/WEB-INF/lib) BUT this is not the case.
2) I also ran a RMI application INSIDE the web application. Perhaps due to above mechanism of classloading, I get the following error
Exception in binding=java.rmi.ServerException: RemoteException occurred in serve
r thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested excep
tion is:
java.lang.ClassNotFoundException: com.mbconsole.adminui.MBrmiAdminServer_Stub
java.rmi.ServerException: RemoteException occurred in server thread; nested exce
ption is:
Because the application could NOT load stub class from WEB-INF/classes directory.
-- My problem is I cannot use "specific API" or make any changes for the Container. As the application is sold for other vendors (Tomcat, WebShere...) and it works in those system.
-- I am sure this kind of problem will be encountered earlier (actually I couldn't find out)
- Any idea will be of Great Help!
Thanks in advance

Thanks Debu for the information.
I indeed was using earlier version. I upgraded to 9.0.3 container and referred to this document
http://otn.oracle.com/tech/java/oc4j/htdocs/how-to-servlet-sysclassloader.html
-- The RMI problem was solved, thanks for that !
But I am still having difficulty. I use XML parsers in $myapp/WEB-INF/lib:
- jaxp.jar - v1.1 specs
- crimson.jar - v1.1 specs
- parser.jar - v1.0 specs
I changed the "orion-web.xml" and included
- "<web-app-class-loader search-local-classes-first="true" />"
When the application started it gave the "sealing violation exception" as follows:
java.lang.SecurityException: sealing violation

If the container loads classes from the local path (WEB-INF/classes, WEB-INF/lib) then this should have worked (coz' the application does works on Tomcat, IBM WebShere...) with the same set of parser.
If I remove the above three parsers, then the application initializes BUT the same problems prelude (i.e. Oracle parsers gives problems like: toString() of XML node returns class name, etc).
2) This is another strange problem. I am using apache soap jar (SOAP 1.1 impl) and uses its SOAP deployement tool. Hence I use "soap.jar" in $myapp/WEB-INF/lib/ directory.
But with the above configuration (local=true) the container uses "soap.jar" from location:
-- $OC4J_Home/j2ee/lib
and this causes the "class not found" Exception.
Again help is required specially for the first point.
Thanks,
Thyagesh

Anybody Please help me out with this issue.....because I am really fed up with this problem....want some urgent help.....
One possible workaround which I could make out is there needs change to be made in the .rdf files in Report Builder and then inside the User Parameters we change the Initial Value to * from % because the Reports Server encodes every value as %Initial_Value% and hence if the initial value for the parameter is % then it does not get a valid value and hence it returns as an invalid xml
But unfortunately it seems this workaround does not work.Please help as soon as possible.

Hi,
you said that some changes were made in the .xml files but i had said that all the files present in Reports Developer or Reports Builder are .rdf files and I had made changes in the .rdf files for this articular report and then compiled it thereitself and then ran a paper layout of the report but the report did not comprise any data.
There was sufficient data also to populate the report. So this may not be a database issue. Please help if you can ASAP.

OC4J application availability control

Can someone please suggest a simple way to make a OC4J application temporarily unavailable for users, so that any request to it returns a "Application not available - try later" page?
Thanks,
Pere

There is no formal way to do this , but can use the following:
1) You can a dummy application with HTML/JSP for this message
2) When you want to make your application unvailable, bind the context root of your apps to the web module of your dummy application.
Hope this helps ..

I did everything what I could find online forums. (Except messing with BIOS settings)

Did you go through the drill
a. video card driver version up to date according to the manufacturer of the video card
b. if so, deletion of the BadDrivers.txt file....for Premiere Elements 12 in Windows 7, 8, or 8.1 64 bit, the path is:
Local Disk C
Program Data
Adobe
Premiere Elements
and in the Premiere Elements Folder is the BadDrivers.txt file for version 12. The BadDrivers.txt file is a file in this Premiere Elements Folder which also contains folders. You do not want anything in those folders. All you want is the BadDrivers.txt file in the Premiere Elements Folder.
Make sure that you have Folder Option Show Hidden Files, Folders, and Drives active so you can see that complete path.
The rationale for the being of the BadDrivers.txt file has its origins in post 10 of the following older thread
http://forums.adobe.com/message/3177024
When you get the display card error message, is it before you import media into the project? And, when you get the message, does the program allow you to continue by pressing a Continue Button or are you stopped from going further?

N82 application problems

Hello everyone. I bought N82 a few days ago and I have an application problems. My installed applications works for 6-7 hours. I can see them in applications folder and application manager. But 7 hours later, I can't see them in applications folder also application manager. Why it happens? Please help me!
I tried those but I can't solved this problem:
Soft format
Hard format
Reinstall N82's software ( V31) with Nokia Software Updater
Formatting memory card and reinstall applications.
Note: I don't have this problem with my videos and musics .Only applications.
Solved!
Go to Solution.

Finally I solved this problem. I bought a new memory card and then installed my app.I think Nokia's 2GB memory card have a problem. (System folder.)

Applications problem: "You cannot update this software since you have not owned the major version of this software."

Hi all,
RE: Applications problem: "You cannot update this software since you have not owned the major version of this software."
Until recently, I have not encountered this problem. And I am facing this problem for both my iPad and iPhone.
I only have 1 iTunes account and the most recent change was that I switched the location from Singapore to UK (I'm currently in the UK). I also updated my applications a couple of times before since the change in location, so I doubt it's due to the location change. I've tried signing out of the account in the iTunes accounts on the devices, then signing back in. I've also tried restarting the devices (and for the iPad, I even updated the iOS).
Any idea what else I can do to try to rectify this?
Thanks and regards,
Tammy

Hi there!
Thanks for replying!
1. Yup, my iOS is the latest (6.0.1), and I have 7 apps on my iPhone that apparently have updates. But it's been 6.0.1 for quite some time and I've also been able to update the apps till just this week.
2. I don't have a credit card associated with my account anymore. Ever since I changed the location, I removed the credit card details. But I didn't have problems with any of my apps (updating or downloading new ones) until this week. Also, all the apps I've downloaded since I came to the UK are free apps.
I still don't know what's wrong.

Deploying an OC4J Application fails

We have created a new OC4J container and are getting errors when trying to deploy a OC4J Application.
We are running 9iAS 9.0.2.2 and are using OEM to do the deployment.
After selecting our .ear file we get no Web Modules on the 'URL Mappings for Web Modules' step (number 3 of 8), should one be found if .ear file is okay ?

Class visibility problems in deployed OC4J application

I have an entity, autogenerated from a database table by JDeveloper, which has the form:
Entity.java:
package a.b.c;
import ...
@Entity
@NamedQuery( ... )
@Table( ... )
public class Entity implements Serializable {
    @Column( ... )
    : etc.
}Then I have a stateless session bean, also autogenerated by JDeveloper, which has the form:
SessionEJBBean.java:
package a.b.c;
import ...
@Stateless(name="SessionEJB")
public class SessionEJBBean implements SessionEJB {
    @PersistenceContext(unitName="Simple")
    private EntityManager em;
    public List<Entity> queryFindAll() {
        return em.createNamedQuery( ... ).getResultList();
    : etc.
}Then I have my client (again, largely autogenerated):
SessionEJBClient.java:
package a.b.c;
import ...
public class SessionEJBClient {
    public static void main(String [] args) {
        try {
            final Context context = getInitialContext();
            SessionEJB sessionEJB = (SessionEJB)context.lookup("SessionEJB");
            List<Entity> entities = sessionEJB.queryFindAll();
        } catch (Exception ex) {
            ex.printStackTrace();
    private static Context getInitialContext() throws NamingException {
     : etc.
}The above code works fine, however I now want to experiment with the oracle.toplink.essentials.tools.sessionconfiguration.SessionCustomizer interface. To this end, I create a bare-bones customizer class:
Customizer.java:
package a.b.c;
import ...
public class Customizer implements SessionCustomizer {
    public Customizer() {
    public void customize(Session session) {
}and make corresponding updates to the persistence.xml file:
persistence.xml:
<?xml version="1.0" encoding="windows-1252" ?>
<persistence
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Hi, you all seem highly intelligent so I'll give this a shot.
We're having a similar problem, but TopLink is not involved. Axis2 is, but in our case, the Axis2 application runs fine, it's the other applications that fail.
We have three applications, Login, Candle, and Webservices (the one with Axis2). When we first start up the applications, they all instantiate fine. We can run Login pages and Candle pages fine. We can also run non-Axis2 Webservices servlets without breaking Login and Candle. But when we run a webservices servlet that uses Axis2, something happens that causes all future Login and Candle class loading to fail! From the error message, OC4J indicates that it is trying to load classes for Login and Candle using the classloader for Webservices.
So, to summarize, once the webservices app runs an Axis2 servlet, OC4J tries to use the webservices' classloader to load classes for the other applications instead of using their classloaders. The example error message I give below is for the Candle application, but the same problem occurs for Login.
Please help, even if it's just a suggestion for something to try!! We've been trying to understand this for 2 days and we're still as stumped as ever.

How to re-execute the above script?. I tried to re-execute the

wwv_modules$ table, but the appimp.cmd script terminated after
the following messages:
...Importing component: ID = 3365687784 Name = TUTORIAL_HRREP

Most Wifi hotspots are configured for PC's and not Macs. Most will work with macs, but will have some issues. Unfortunately there is no way to solve this other than asking the hospitals to update their wifi network with Mac-friendly wireless routers
How do you configure a hot spot for PC only? What are "Mac-friendly wireless routers"? Hot spots use wifi technology based on 802.x. This is a wifi standard supported by wifi routers, PCs, and Apple products.

URGENT! MAJOR PROBLEM! Application Builder ICON - I CANNOT SEE?! WHY?

Hello,
I have just installed XE and I cannot see the Application Builder Icon on the Home Page!? Please help...do I have an old version perhaps?
Kind Regards,
Kajani

Hi Kajani,
which user do you use to log in?
Is it SYSTEM or a user called TEST? It won't work with either one, since those are internal accounts which don't provide the application builder.
You have to create a new user and log in as this new user.

Deploy to OC4J standaone problem

Dears,
I developed an application in jdev 10.2 and it works successfully with embedded OC4J, but when deploy to OC4J standalone or Tomcat it doesn't work.
I use JSON in my application.
The log (for OC4J standalone and Tomcat) is empty from errors and exceptions, Only
JSONRPCBridge.analyzeClass analyzing package1name.package2name.package3name.DAO.classNmaeDAO
is written and my code didn't work and JSP is empty.
Any ideas, what may be the problem there???

When I deploy to oc4j from jdev... I get an error.
Unknown site: http-web-site
How do I figure out what my http site is via my oc4j configuration?
I know in my Connection properties for oc4j in jdev, there is a target web site property where I entered "http-web-site", thinking this was the correct target.
Thanks. Look in <oracle_home>\j2ee\home\config\server.xml
Web sites are defined by the web-site entry. E.g
<web-site path="./http-web-site.xml" />
<web-site default="true" path="./default-web-site.xml" />

Urgent----OC4J Hanging After every 4-5 Hours

Respected All Oracle ADF Users,
I Have Developed very large ADF (ADF BC Swing) Application i.e. One ERP Product, It Contains 300 Application Modules (Forms). I deployed this Application as EJB Session Bean on standalone OC4J which is on Fedora Core 3. There is Very Huge Data Entry, Data Fetching through this Application. (Daily 100000 Records Insertions)
Now problem is, when I start OC4J it goes fine for next 4-5 hours, but after 4-5 hours it get hang or my application get hang .if I restart my OC4J then it will run fine for next 4-5 hours and after 4-5 hours again it hanging ,so in a day I have to restart OC4J 4 times.
So I can u tell me
1) Is OC4J not support such kind of large application?
2) Weather I have to go for Oracle Application Server?
3) Is there any kind of setting needs for same problem?
4) Is this an Operating System Problem?
5) Is this a Server Compatibility Problem?
Please guide me.
Thanks

Hello,
I ran into a similar problem running an application server instance on a SLES 9 machine. My application was much smaller than yours and it turned out that I was forgetting to release a connection to an LDAP server from Java code. So, I suggest you have a look at all suspicious bits of code first.
Regarding the going to Oracle IAS, I would certainly advice you to do so.
Finally, a last piece of experience that I can share with you is that before getting SLES I used to run my application server on SuSE 8.2. While all the required packages were there the ias instance appeared to use all the available system memory. The issue was resolved until I finally installed the Oracle supported SLES.
If you like the Red Hat "look and feel" but still don't want to get a Linux that requires subscription like Oracle EL, why not try CentOS (www.centos.org) which appears to be a very good Red Hat clone.

Oc4j restart problem.

Hi ,
By using controller i am running my script ,the script is taking to OHS and OHS is routing the request to OC4J .It was working fine for the first time .i need to stop the oc4j and again bring back the oc4j server,this time OHS is routing the request to OC4J but the OC4J is not able to handle the user requests. We found the below error repeatedly in the application log file.
" Caused by: java.lang.ClassCastException: narrow () failed for class:com.siebel.nexus.repository.runtime.helper.RepositoryServiceRemoteHome

To restart Oc4J it has be be up and running.
1) So please start the Oc4J server as follows in one window:
java -jar orion.jar --> starts
2) Go to another command window:
Now try to restart Oc4j as follows:
java -jar admin.jar ormi://localhost admin password -restart
Hope this helps !!

>sf003dell is Oracle 8.16 server, I also tried to point to my 9iDB got the same message. Before each trial, I did modification on datasource.xml file under my j2ee container.I can start OC4J in a basic format "java -jar orion.jar" without error displayed.
I can also setup connention to both DBs from jDev5.0 very easily. Anyone in this forum can give me a clue what is going wrong?
Thanks a lot,
