CORBA in OC4J not working

Hi all,
I have completed instalation of O9iAS (Win 2000) and OC4J without any errors but I am still unable to run petstore in OC4J. I can populate the tables but any call of mainservlet results in 500 internal error. As obvious from stack trace, corba is not configured properly. What do I need in order to make Corba working (classpath, environment variables) in OC4J?
part of stack trace:
java.lang.ExceptionInInitializerError: org.omg.CORBA.INITIALIZE: cannot instantiate com.netscape.ejb.client.Util minor code: 0 completed: No

Peter -
I believe (last I heard) that OC4J does not yet fully support everything needed for CORBA...if someone has heard differenly, they can chime in...

Start oc4j not working

Hi
I am using OBIEE 10.1.3.4 on my machine for the past 2 months and everything was fine till last week. When I start oc4j from Start - Programs - Oracle Business Intelligence - Start OC4J, console comes up and quickly vanishes i.e. its not being started. Due to this I can't use Presentation, publisher etc. I can't even open Systems management page to set oc4jadmin configurations.
Do I need to do/check some settings? Any pointers to solve this issue will be highly appreciated.
Thanks
AK

To be clear, what is the exact behaviour you've got? : -
can you access the presentation services login page?
do you get a 500 internal server error?
do you get a host not found type error?
You'll find your presentation services logs in <oraclebidata>/web/log/sawserver.out.log
Check analytics log here: <OracleBI home>\oc4j_bi\j2ee\home\application-deployments\analytics\application.log
Check your logs in here too: <oracle BI home>\oc4j_bi\j2ee\home\log

Application restart not working in oc4j

I have an application that runs if I stop and start oc4j using stop and start options, but if I restart from em console it does not work properly eventhough em says the status is up.
Using oc4j 10.1.3.3
The application starts thread in ContextInitialzed() method of ServletListener which implements ServlerContextListener. Does it have to do anything with that.
Also the application does not log to the logger which is set using JVMARGS -Djava.util.logging.config.file in oc4j.cmd file. It logs when oc4j is stopped and started.
Any ideas?

Greetings,
Are you looking in j2ee/home/log/oc4j/log.xml for your log information? Also, you can set the level of logging to FINEST in your j2ee-logging.xml. Once this is done please post the logging info relevant to your issue.

OC4J JSP Debugging not working for all the jsps

Hi,
Initially I was not able to debug jsps using Eclipse and OC4J. The jsp debugging started working once I made the below changes:
1) global-web-application.xml is modified
Changed the attribute development="true" in orion-web-app
Added the below init param for the JspServlet
<init-param>
<param-name>debug</param-name>
<param-value>class</param-value>
</init-param>
If the jsps are present in a sub directory under the webcontent none of the breakpoints are working. I am still be able to view the jsp pages on the browser.
Tools: Oracle 10g Application Server Standalone version(10.1.3.5.0), JDK5, Windows XP, Eclipse Indigo
Project Structure:
Test (Eclipse Dynamic Web Project)
-WebContent
Sample.jsp ( Breakpoints are working)
-subF (Folder)
SubSample.jsp (Breakpoints are not working)
-WEB-INF
web.xml
Debugging worked for http://localhost:8888/Test/Sample.jsp
Debugging not working for http://localhost:8888/Test/subF/SubSample.jsp
Any help is highly appreciated.
Regards
Danny

This tells there is not enough main memory (not disk space) for the program to run.
- You can look the dump in ST22, it will have suggestions on increasing the ROLLAREA??, you can forward that to Basis.
- Most likely you will not have any more memory to assign so the above may not be feasible. Try to rework your query so it works with less data.

Embedded OC4J Bindings Not Working

I am having trouble with loading an AppModule using the 10.1.3 OC4J Embedded AS. When try creating an ADF panel binding I get the following error:
     javax.naming.NamingException: Lookup error: javax.naming.AuthenticationException: No such domain/application: "current-workspace-app/current-workspace-app";
However, I can get a working reference to the AppModule using:
     env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
     env.put(Context.SECURITY_PRINCIPAL, "oc4jadmin");
     env.put(Context.SECURITY_CREDENTIALS, "welcome");
     env.put(Context.PROVIDER_URL, "ormi://localhost:" + RMI_PORT + "/current-workspace-app");
     Context ctx = new InitialContext(env);
     AppModuleHome ejbhome = (AppModuleHome)PortableRemoteObject.narrow(ctx.lookup("AppModuleBean"), AppModuleHome.class);
     RemoteAppModule ejb = ejbhome.create(env);
but I cannot use that in a data binding. Why does the first one using the generated code not work?

Hi,
tried with JDeveloper 10.1.3.3 and this works for me. Try JDeveloper 10.1.3.3 - if it doesn't work, have a closer look at your sessionFacade

Servlet forward not working with portal and oc4j

Scenario: page1.jsp, page2.jsp, MyServlet
Page1.jsp posts a form to MyServlet which then does some processing and forwards to page2.jsp.
Tests:
Works fine as a standalone app under oc4j.
Does not work as oc4j-driven portlet under latest portal. Specifically, it conks out on the forward.
Question:
Why?
What is the suggested workaround?
Michael Mogley
Software Engineer
LRN, Inc.

James, thanks for responding but you are misunderstanding the problem. I have been able to do multipage and form-submit portlets as you describe for a long time. The issue is I am not able to use the jsp-forward directive within a validation servlet when using oc4j with portal. Here is what I'm trying to do in pseudocode:
EntryPoint.jsp
1. Enter form data.
2. Submit form to MyServlet.
MyServlet
1. Validate form.
2. If valid, <jsp-forward page="success.jsp"/>.
3. Else, <jsp-forward page="failure.jsp"/>.
The above works fine when used in an app running on oc4j outside of portal. It does not work when the same oc4j app is portletized. By the way, the portletized app WILL work if I change jsp-forward to jsp-include. So the problem is obviously in the forwarding.
Michael
I would try looking at the samples in the PDK-Java V2 that show how to do form input and multipage behavior. The form input shows you how to make a form in a portlet that when you submit it, the entered values appear in the portlet. The multipage portlet shows you how to have a portlet display one page and then when you click on a link, it shows you the second page.
It may make sense to copy the same code used for the samples and just tweak it to create a form that passes values from page1 to page2.
For more info on V2 parameters, see the article "A Primer on Parameters and Events" in the PDK-Previews (for subscribers to Developer Services only). You can also see the V1 article called "Understanding the Parameter Passing Portlet" for more info on parameter passing with portlets in V1.

Remte JSP debugging for standalong OC4J 10.3.x not working

Follow the next steps:
1. Copying the ojc.jar, jdev-rt.jar and jdev-remote.jar to the OC4J_HOME/lib
directory
2. Add the next lines to the application.xml file
< !-- Remote Debug settings -->
< library path="../../../lib/jdev-rt.jar" />
< library path="../../../lib/ojc.jar" />
< library path="../../../lib/ojmisc.jar" />
3. Change the global-web-application.xml in a text editor.
From the following section:
< orion-web-app
jsp-cache-directory="./persistence"
servlet-webdir="/servlet"
development="false"
>
Change development="false" to development="true" to enable servlet
debugging.
4. In the global-web-application.xml file, modify the jsp servlet tags to be:
< servlet>
< servlet-name>jsp< /servlet-name>
< servlet-class>oracle.jsp.runtimev2.JspServlet< /servlet-class>
< init-param>
< param-name>debug_mode< /param-name>
< param-value>true< /param-value>
< /init-param>
< init-param>
< param-name>developer_mode< /param-name>

< param-value>oracle.jdevimpl.jsp.JspOjcCompiler< /param-value>
< /init-param>
< load-on-startup>0< /load-on-startup>
< /servlet>
5. Start the oc4j using the next command:
java -hotspot -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=4000 -jar oc4j.jar
6. Deploy the application
7. Select the Remote Debugging and Profiling option in the Run Configuration
for the project with the jsp to debug.
8. In the Debugger/Remote section of the run Configuration set the host, port
and timeout to the correct ones (name of the computer where you are running
the application).
When trying to run the jsp you are going to get the error:

/*@lineinfo:generated-code*/
and compiler is generating next message in console:

and doesn't want to compile MyPage.java.
I need help with this problem! And i don't have any ideas how to solve it. People, help me, please!

Dear dvohra, have you ever try yourself the method, which you suggest?
It is not working!
If i try to configure OC4j like in blog, IDE doesn't stop in JSP's break points.
So, I need in 100% working solution for remote debugging on oc4j 10.3.x. The main reason of using remote debug for me is that i have to develop portlets, and i have to invoke my portlets from portal. It is posible only when i deploy my portlet on stand alone oc4j!
I really need remote debug! And i'll be very thankful someone for 100% working solution!

Response.addCookie() not working on OC4j stand alone server

Hi,
I have problem with response.addCookie(). see the code below:
if ((isCookie == null)||(!(isCookie.equals("yes")))) {
String cookiestr="I am OK";
Cookie m_cookie = new Cookie("msign",cookieStr);
m_cookie.setMaxAge(300);
response.addCookie(m_cookie);
This part of the code is in Struts Action class. The read Cookie part is in JSP.
Cookie[] cookies= request.getCookies();
if(cookies != null)
for (int i = 0; i < cookies.length; i++)
if (cookies.getName().equals("msign"))
String infor = cookies[i].getValue();
response.sendRedirect("hellow.jsp");
break;
Add cookie and read cookie work fine on my computer If I runs application on JDeveloper 10g embeded OC4j server. I can see the cookie in the Temporary Internet files
However, I deployed the application on OC4j standalone server, it does not work. response.addCookie() does not work at all. The cookie is not sent to the browser at all. There is no this cookie in Temporary internet file. The page is not directed to hellow.jsp.
Does anybody here know why? Any idea?
Thank you very much!

Dear All
Just to share the solution of the problem.

Hello,
The first step if to find the PL/SQL line causing the error in 'cf_1formula':
create a procedure Trace in your Reports : (modify the line trace_file := Text_IO.Fopen('d:\temp\rep_trace.txt', 'A'); to adapt the filename to your system)
PROCEDURE Trace (trace_string in varchar2) IS
trace_file Text_IO.File_Type;
BEGIN
trace_file := Text_IO.Fopen('d:\temp\rep_trace.txt', 'A');
Text_IO.Put_Line(trace_file, trace_string);
Text_IO.Fclose (trace_file);
END;
Then, add some calls to this procedure in the program unit 'cf_1formula'
trace('Before line 1';
<PL/SQL code of line 1>
trace('Before line 2';
<PL/SQL code of line 2>
trace('Before line 3';
<PL/SQL code of line 3>
Excecute the Reports and find in the file 'd:\temp\rep_trace.txt' the last line executed.

Report service is not working after install Discoverer..............

Hello,
I have installed Oracle Developer Suite 10gR2 (Forms/Reports) on my desktop, they were both working fine for a long time. I installed Discoverer 10gR2 (Administrator and Desktop) on the same machine recently. The Oracle Forms is still good, I can run forms on the local machine after I start OC4J instance. But the Reports is always hanging, even Showjobs. I can access http://host:port/reports/rwservlet, but anything under that is not working, hanging.......
Please help! Thanks in advance.

Hello,
The problem may be a PATH problem.
Start the reports server after having set the PATH :
set ORACLE_HOME=d:\oracle\ods1012
set PATH=%ORACLE_HOME%\jdk\jre\bin\classic;%ORACLE_HOME%\jdk\jre\bin;%ORACLE_HOME%\jdk\jre\bin\client;%ORACLE_HOME%\jlib;%ORACLE_HOME%\bin;%ORACLE_HOME%\jdk\bin;%ORACLE_HOME%\jre\1.4.2\bin\client;%ORACLE_HOME%\jre\1.4.2\bin;

Client.ole2 is not working

Hi i'm migrating to from fomrs 4.5 to 10g as DDE package are not supported in the
10g. i'm using client.ole2
I have written following code to open a stored excel sheet(which is a template for entering the data). this is not working not giving any error.
please tell me where is the error
declare
application client_ole2.obj_type;
workbooks client_OLE2.OBJ_TYPE;
workbook client_OLE2.OBJ_TYPE;
worksheets client_OLE2.OBJ_TYPE;
worksheet client_OLE2.OBJ_TYPE;
worksheet2 client_OLE2.OBJ_TYPE;
worksheet3 client_OLE2.OBJ_TYPE;
args1 client_ole2.list_type;
L_PATH VARCHAR2(100);
COMMAND1 VARCHAR2(5000);
BEGIN
l_PATH := SFN_GET_DIRECTORY_PATH('DIR0003');
COMMAND1 := L_PATH||'\Formats\EMP_NEW_UPLOAD.xls';
application := Client_OLE2.create_obj('Excel.Application');
workbooks := Client_OLE2.Get_Obj_Property(application, 'Workbooks');
args1 := Client_Ole2.create_arglist;
Client_Ole2.add_arg(args1, 'c:\emp.xls');
workbook := Client_Ole2.invoke_obj(workbooks, 'Open', args1);
worksheets := Client_Ole2.get_obj_property(workbook, 'worksheets');
CLIENT_OLE2.destroy_arglist(args1);
CLIENT_OLE2.SET_PROPERTY(application,'Visible',1);
CLIENT_OLE2.SET_PROPERTY(application,'DisplayAlerts',0);
end;

As Gerald Krieger suggests, it sounds as if you have not installed the Jacob library correctly. Most WebUtil functions, like CLIENT_GET_FILE_NAME, are included in the base 10g install -- OLE functionality, however, is not. This is because the Jacob library, which is required for OLE support, is not an Oracle product and, as such, could not legally be distributed by Oracle.
Jacob can be downloaded from http://sourceforge.net/projects/jacob-project
Configuring the OC4J for developing/testing OLE-enabled forms involves these steps:
1. Download the Jacob library and extract two files -- jacob.jar & jacob.dll
2. Place a signed copy of jacob.jar in ...\forms\java
3. Place a copy of jacob.dll in ...\forms\webutil
4. If you are not using Jacob 1.8, but are instead using a different version, you must edit ...\forms\server\webutil.cfg by locating the line which contains install.syslib.0.7.1=jacob.dll|94208|1.0|true and replacing 94208 with the size (in bytes) of your particular version of jacob.dll
If these instructions are unclear, please accept my apologies and refer to the WebUtil documentation for details.
Finally, be aware that your forms will not deploy correctly unless ...\forms\webutil.pll has been compiled. You must be connected to a WebUtil-ready database in order for webutil.pll to compile successfully.
Hope this helps,

Jms is not working properly in clustered environment

Hi all,
i am using the application server oc4j 10.1.3.1.0 enterprise edition . my application is standalone application(thick client)
we are using the jndi.properties as follows ...
java.naming.factory.initial=com.evermind.server.rmi.RMIInitialContextFactory
java.naming.provider.url=opmn:ormi://172.16.1.38:6005:group/Security,opmn:ormi://172.16.1.38:6006:deceval_group/Security
java.naming.security.principal=oc4juser
java.naming.security.credentials=oc4juser
oracle.j2ee.rmi.loadBalance=lookup
we have two application servers in cluster topology as u can see above we have used one instance from one application server and one from another.
i have seen that for every instance there one jms server. at runtime it is taking one application servers services
say opmn port 6005 but when the application is connecting to the another application server say opmn 6006
here jms is not working properly when i send message
As we have clustered environment message must be propagated all the applications who use above jndi.properties.
if i keep use only one application server opmn say
java.naming.provider.url=opmn:ormi://172.16.1.38:6005:group/Security
then its is working excellently
please can u provide any solution ASAP
thanks in advance
