MapViewer JDeveloper embedded OC4J installation error

Hi,
I downloaded all latest mapviewer.ear and latest OC4J.
Followed MapviewerUG installation instructions
After starting OC4J
using the url http://localhost:8888/mapviewer/
works well and the demos like jview also works well
using the url http://localhost:8888/mapviewer/omserver
however, generates the following error
<?xml version="1.0" encoding="UTF-8" ?>
<oms_error>Message:[oms] empty or null xml map request string.

I also downloaded the latest JDeveloper 10G and JDeveloper extensions and follwed the instructions in the How To Document
How To Build Dynamic Maps Using JDeveloper 10g and Oracle Application Server MapViewer
An Oracle JDeveloper How To Document
Justin Lokitz
October 2004
I have no compilation errors but I am not able to view the density map. I am getting the Internal Server Error 500 instead.
Can anyone please guide me through this.

Hi Joao
Thanks for tip on the log file.
I have the data loaded.
Evrything works fine when I use Mapviewer with OC4J and try the jview demo.
I am however not able to get the example 'How to build Dynamic Maps' running using JDeveloper using the embeded OC4J server.
The jsp source is as follows
<%@ taglib uri="http://xmlns.oracle.com/j2ee/jsp/tld/spatial/mvtaglib.tld" prefix="mapviewer"%>

There are no comilation errors
When I run the code I get 500 Internal Server Error.

Error message running application from Jdeveloper/embedded OC4J

Does anyone know what configuration I am missing to be able to run a web application from JDeveloper with the embedded OC4J.
Here are the error messages that I am getting:
PM oracle.j2ee.jndi.JndiMessages warningInvalidResourceReference

I should be able to run the application from Jdeveloper development environment without deploying to Tomcat after each change.
There must be a jndi configuration that I need the questions is where?
Is this configuration or lack of configuration documented some where by Oracle?
Thanks

Hi, user544716,
did you solved the problem? I got exactly the same problem. In my case, my application runs well with jdeveloper 10.1.2 but when migrated to jdeveloper 10.1.3.1, the emdedded OC4J won't wrok and generated the same error as yours.
Thanks.

Problem with Jdeveloper Embedded OC4J XML parsing

Hi all,
I am having a problem getting jdeveloper to work well. If I use jdeveloper to build the WAR file for my app and I deploy to Tomcat, the app runs fine with no error.
However, if I try to run my app within the jdeveloper, I get this error -

I have tried to turn off XML parsing within Jdeveloper but no luck. I don't understand why jdeveloper will be trying to implicitly parse the XML doc, and wont even do it well.
Is there a way I can turn off Embedded OC4J XML parsing ? and let it just use the parser in the application ? I mean Tomcat works fine with this application.
Please help !

I think maybe you use wrong adf lib when deploying your project to the OC4J.
You can update your oc4j in the jdev.[JDEV->Tools->ADF Runtime Installer-> Standalone OC4J].
Good luck

Starting embedded OC4J gives error XML-20108: Start of rootelement expected

Product JDeveloper 10.1.2.0.0 (Build 1811)
Up until recently I never got any errors when I started the embedded OC4J-server.
Now I get the above error.
It looks as if JDeveloper tries to access server.xml twice. The first process is updating the server.xml, and when the OC4J-server is starting up, it also tries to access server.xml, which is empty at that time (being updated by the other process).
How can I solve this?

JDeveloper embedded OC4J accessing remote database

How do I configure the embedded OC4J JNDI w/JDBC to use a local TNSNames.ora file setting to connect to a remote 9i database?

You might want to consult the OC4J admin guide.
http://download.oracle.com/docs/cd/B31017_01/web.1013/b28950/adminclient.htm#CHDCFBIH
For the embedded OC4J you can access datasource settings through tools->Embedded OC4J preferences.

Error logs for Jdeveloper embedded oc4j

Hi guys,
I am currently using the oc4j embedded within jdeveloper (9.0.2) to develop and obviously to debug some code.
When there is an exception in the init() method, there seems to be no record of it in the logs, the only log I found are in jdev/system/oc4j-config/log, specifically the server.log
I have found ArrayOutOfBounds and other unchecked exceptions, but not the Servlet or IO exceptions to be logged there. Anyone have any clues how I can set it to log those as well? or does it not do that?
Thanks lots,
H2O

I think that i they works is lucky, because your two modules get managed through the same class loader in your standalone oc4j
Correct if I'm wrong, but you should not trust using local references if they aren't implemented in the same instance of the classloader, which you can control

JDeveloper 3.0 Installation Error

If the RDBMS and the WeDB listener are actually running, you are
probably simply short of memory. Try stopping these and then
launching JDeveloper.
It seems happiest when you have at least 128 MB of ram for it
and it alone.

JDev 10.1.3: Problem deploying a session bean to embedded OC4J

JDeveloper 10.1.3, TopLink, OC4J, WinXP, java 1.4.2_05.
I used TopLink to create a set of Java objects from a DB Schema, then created a simple Session Bean to read some of the objects. Everything compiles fine.
JAVA_HOME points to the JDK (not JRE) and CLASSPATH is empty (undefined).
When I try to Run my session bean in the jdeveloper embedded oc4j, I get this message. Thanks in advance for your help.

OC4J Log Error Interpretation

Hi, I am trying to debug an authentication issue using a system based on the information in this article: http://www.oracle.com/technology/products/jdev/howtos/1013/oc4jjaas/oc4j_jaas_login_module.htm
IE database/datasource based authentication.
I am getting the following error in the applications OC4J log every time a login attempt is made, no error is seen from the application, authentication simply fails.
When I had the recommended code for fine logging in the j2ee-loggin.xml file (<logger name="oracle.j2ee.security.oc4j" level="FINE" useParentHandlers="false">
<handler name="oc4j-handler"/>
<handler name="console-handler"/>
</logger>) there was no information at all recorded in the OC4J log, not until I removed the extra logger code from that file did entries such as the following begin appearing in the log file. What could be going wrong here? Why is the login process generating a null pointer error and why would the log file not be written too when the fine logging code was added to the config file? Any idea's? All I can really gain from this error message is that the DBTableOraDataSourceLoginModule is at some stage atleast being referenced or called.

JAAS-OC4J: Authentication failure for user: TATKINS
JAAS-OC4J: Membership check for group: USER failed for user: anonymous
What i cant work out is what is causing the login module to abort and raise a null pointer exception. Could this be due to a configuration mistake in the console manager or one of the xml files prior to deployment? I just have no idea how to approach fixing this issue.
I really would appreciate some assistance, 5+ days trying to get this working. I had this working on jdeveloper embedded oc4j, and all the tute's on standalone deployment pass off the configuration of standalone as simple compared to embedded, yet don't go into enough detail to get it working, atleast from my perspective.

I`d appreciate if anybody can tell me what i can do!

Hi,
please go to Jdev_home\j2ee\home and type java -jar oc4j.jar in a command window. This should - hopefully -provide us with additional exception traces

Jdeveloper 11g TP4: Connection refused error for Embedded Oc4j

Hi,
I am getting following error whenever trying to deploy any application in embedded oc4j or whenever try to connect with embedded server on Resource palette.
Error while getting remote MBeanServer for url: ormi://127.0.0.1:23891/default:
Error reading application-client descriptor: Error communicating with server: Connection refused: connect; nested exception is:
     javax.naming.CommunicationException: Connection refused: connect [Root exception is java.net.ConnectException
I am using Jdeveloper 11g TP 4 on windows XP.
I have checked other links too related to above error and have checked following:
Proper host name entry in host file
No spaces in Jdveleoper installed directory name
Proxy setting in Jdeveloper: excluded localhost and ip address
Will be very thankful if anyone can help me to resolve this issue.
Thanks in advance

Don't spend to much time on this. JDev 11g is production and there will be no OC4J 11g!

I don't think it involves spaces in the JDeveloper installation folder. Other developers in my office have JDeveloper installed in a path with no spaces, and they see the same problem. Actually, we don't even need to create a web application to see the problem. We see it when creating a new application server connection with the standalone OC4J 10.1.3 and clicking Test Connection:
Error while getting remote MBeanServer for url: ormi://localhost:23791/default:
Error reading application-client descriptor: Error communicating with server: Connection refused: connect; nested exception is:

The only changes I've made in my application was unchecking the Extensions I'm not using in my application. After changing these Extensions (this is a tip regarding memory-consumption of jdeveloper) I'm getting these errors in the realm-dialog.
Regards,
Nathalie
PS: I've unchecked the following extensions:
- ADF Security 10.1.3.40.66
- BI Beans Graph 10.1.3
- Oracle Webcenter Preconfigured OC4J 10.1.3.2.0
- Portlet Creation Extension 10.1.3.40.66
- Versioning Support 10.1.3.40.66

Hi,
OC4J needs to be configured to support HTTP and HTTPS sessions. Because the embedded OC4J uses the default-web-app configuration during testing I am not so sure about configuring it for HTTPS. However, in this case I suggest you test it as a stand alone container in which case HTTPS configuration happen as described in the OC4J security guide.
"How do I make the Embedded OC4J redirect http requests for secure web content to https automatically as required in the servlet 2.4 spec ?"
I don't find this statement in my version of the Servet 2.4 spec. Can you point me to the line in the document?
If you mean transport guarantee, then this is not exactly what you say:
"The transport-guarantee element specifies that the communication between client and server should be NONE, INTEGRAL, or CONFIDENTIAL. NONE means that the application does not require any transport guarantees. A value of INTEGRAL means that the application requires that the data sent between the client and server be sent in
such a way that it can’t be changed in transit. CONFIDENTIAL means that the application requires that the data be transmitted in a fashion that prevents other entities from observing the contents of the transmission. In most cases, the presence of the INTEGRAL or CONFIDENTIAL flag will indicate that the use of SSL is required."
Servlet 2.4 spec
This however doesn't mean automated redirect to https but says that this requires SSL, which means that a http error is thrown if https isn't used

Error in Embeded OC4J while deploying SessionBean

I am using Jdeveloper version 9.0.5.1, since the project have brought to production at 2004, I have been using the same version.
The workspace a number of project each contains a number of entity and session beans(EJB 2.0), lately I added a new project which contains a new session bean that references another session bean and an entity bean, when I attempt to run the application in the Jdeveloper the embedded OC4J returns the following errors messages:

I dont know what is the meaning of this error, nor what is the cause as it never appeared before. Surprisingly the behaviour of the application seems to be behaving normally even though despite this error and when the Oc4J returns done does this mean it started successfully, this error is preventing me from deploying my application to production environment as I guess there's something abnormal going around.
Note:When I get a fresh copy of the application without the new project which contain the session bean the OC4J starts with no errors.
Any ideas what maybe the problem ?

Is your new project trying to access the database?
SQL error: Io exception: The Network Adapter could not establish the connection
Seems to indicate that you have a problem accessing the database probably due to wrong settings of the database connection information.
Also check your data-sources.xml file for any new entries.
