Restart of OC4J required ? If orion-application.xml changes

Hello,
If i make a change in the orion-application.xml, basically i am interested in changing the JAZN LDAP configuration settings --- do i need to restart the OC4J ?
If yes, where is this mentioned in the documentation ?
Does the answer (yes / no) apply to all versions (10g minor versions) of OC4J.
Please confirm.
Thanks in advance.
Warm Regards
AB

Hi Deepak,
I fully agree with you that changes in the orion-application.xml require a restart.
Infact, when i do that practically, a message is displayed on the OEM console that the changes have been saved to the XML file but for the changes to take effect, i need to restart my container.
Agreed.
But where is it specifically mentioned in the official documentation ?
In the link you forwarded, there is not a single mention about orion-application.xml
Every statement over there talks about jazn.xml
I even checked the documentation for orion-application.xml, there too i could not locate that statements like you gave "any change to the jazn configuration (either in jazn.xml or otherwise) will need a restart."

OC4J orion-application.xml - elements and attributes

Hi. i read in oracle docs sentense like this: "Each property maps to an element attribute in the orion-application.xml descriptor." These properties are from deployment plan and i need to know what is the name of the element in orion-application.xml wich is mapped to webSiteBinding property (from deployment plan).

I just did a quick test of this, and it seems to work for me.
I used the following XML:
<?xml version="1.0" encoding="iso-8859-1"?>
<Employees xmlns="
http://www.foo.com/Employees">
<Employee Id="001">
<LastName>Davis</LastName>
<FirstName>Kirk</FirstName>
</Employee>
<Employee Id="002">
<LastName></LastName>
<FirstName>James</FirstName>
</Employee>
<Employee Id="003">
<FirstName>Anthony</FirstName>
</Employee>
<Employee>
</Employee>
</Employees>
With the XPath "/Employees/Employee" I got rows in the data
set and things displayed fine in my page. Changing it to
"/employees/employee" caused the data set to have no rows which I
would expect since things should be case sensitive.
Can you provide me with some sample XML and XPath that
doesn't work?
Thanks!

Newbie: orion-application.xml in both deployment and applications dirs

Okay,
I am using OAS 10.1.2.2 and have deployed an OC4J instance with a web application. The web application that I deployed (from a .war file) was installed normally but for some reason I have an orion-application.xml file in both the +/application-deployments/webappname/+ and the +/applications/webappname/META-INF/+ directories. They look almost identical with the differences noted below:
applications directory version:
This file has a complete definition for the jazn provider but is missing a reference to the principals.xml file.
jazn section looks like this:
     <jazn provider="LDAP" location="ldap://ldap.server.edu:389">
          <property name="ldap.user" value="cn=username" />
          <property name="ldap.password" value="!password" />
          <property name="ldap.cache.session.enable" value="false"/>
          <property name="ldap.cache.realm.enable" value="false"/>
          <property name="ldap.cache.policy.enable" value="false"/>
          <property name="jaas.username.simple" value="true" />
          <jazn-web-app auth-method="SSO"/>
     </jazn>
application-deployments directory version:
It points to a principals.xml file and gives a generic definition for the jazn provider (specifies provider="LDAP" and a default-realm but no location attribute in the jazn tag).
jazn section looks like this:
     <jazn provider="LDAP" default-realm="whidbey1">
          <jazn-web-app auth-method="SSO"/>
          <property name="jaas.username.simple" value="true" />
     </jazn>
I assume the one defined in the +/applications/webappname/META-INF+ is the proper one since it has all the detailed OID connection information. However, are both needed? If so, why? If not, which one is being used and why would there be two of them?
I've checked all the documentation and have found several references to it being installed in one or the other place but not both.
Any help you can provide would be much appreciated.

Hi,
The difference between these files is this:
The one in the applications/ tree is the one that comes packaged in your ear file. This is a way to package your deployment preferences. At deployment time, enterprise manager extracts this file to configure your deployment.
The one in the application-deployments directory is the one that is actually in use.
LDAP connection from OC4J containers is specified on the container level, because this is container-level security. This means that using the enterprise manager, you configure your container to connect to the LDAP (enterprise manager, tab administration, item Identity Management). In the orion-application.xml, you no longer need the details because they are stored on container level. So these are removed when deploying your application, leaving only what you see.
The configuration parameters you specify can be added as container startup parameters using -Dparam=value.

Integrating orion-application.xml deployment with JDeveloper?

Hi all,
I am trying to create JAAS secured web/ear application but haven't found the
way to integrate the orion-application.xml file in the JDeveloper
deployment process. An alternative would be to insert orion-application.xml tags
into orion-web.xml and copy this one to the usual WEB-INF along with web.xml
another possibility would be directly copying orion-application.xml to the
%J2EE_HOME%\application-deployments\MyApp\orion-application.xml after deployed
in the OC4J Server, but would be lot easier just having JDeveloper deploy it
automatically, what is the way to do it?

Giovanni

The middle of that thread (read the beginning to get the full context) has an answer relevant to your question here.
------ begin quoted --------------------------------------------------------------------
Hello,
JDeveloper 9.0.2 is limited in this area unfortunately. For the use case you are describing, there are two work-arounds:
1) Use an Ant build file (or any other script) as you mentioned.
2) Do your testing in the embedded OC4J server instead of an external OC4J server. You should then be able to make manual changes to the orion-application.xml file used by the embedded server -- it's in the Workspace directory and has a name like "Workspace1-oc4j-app.xml".
We were expecting users to use Oracle Enterprise Manager (OEM) to configure production J2EE applications, since JDeveloper is a development tool whereas OEM is the real server administration tool. For some time, we've debated internally on the JDev team whether that kind of feature separation across Oracle products makes sense. It's clear that developers like you need to perform some administration tasks in the course of testing a production app, so we focused on allowing that for JDeveloper's integrated OC4J server ("embedded OC4J") and left the administration of an external OC4J server to OEM.
For future JDeveloper releases, we will probably have an increasing level of direct support for OC4J administration, but to what extent we will pursue that is still in discussion.
For 9.0.3, I've filed bug 2392697 to track the issue you are reporting (with reference to this OTN thread) to make sure that it is resolved properly for the 9.0.3 release.

Autocreate-tables="false" orion-application.xml

using oc4j standalone(9.0.3). CMP2.0. jeveloper(9.0.3).
The jdeveloper Domain UML entity diagram and generated
entity beans are deployed with default tables generated. The EJB2.0 Dev Guide(9.0.3), says to copy the generated orion-ejb-jar.xml from the deployment directory to the source meta-inf directory to prevent the tables from being re-genrated in the database. However the EJB2.0 Howtos say to set autocreate-tables="false" in orion-application.xml to do this.
Do I need the orion-application.xml file in the application ear file in addition to the orion-ejb-jar.xml? So far I've been able to deploy and run without any orion files, and I would rather keep them to a minimum

"Self I said..."
Got frostbite waiting for a reply. I tried deploying
with just the orion-ejb-jar.xml in the application ear file. Table were not created, so it looks like I can go with just one orion file for now. I can leave the orion-application.xml with autocreate=false, out of the ear file, for now anyways.

Orion-application.xml

I am packaging an application for deployment. Using JDeveloper, I created an orion-application.xml and it was placed in src/META-INF. When I deploy to an ear file, I see that my orion-application.xml is packaged. However, when I deploy it to my stand-alone OC4J instance, a new, default orion-applicaiton.xml is created and mine is nowhere to be found. I see no errors reported in any of the logs about any possible syntax errors with mine. Anyone know what I may have done wrong? Thanks!

Did you check how the EAR was formed by your JDeveloper? There should be an orion-application.xml file with in META-INF dir starting from the root of your ear file check for this.
Any how when it you deploy to standalone oc4j, it modifies your packaged orion-application.xml file a little bit i.e it addes the items to it and then deployes.
The items that gets added to orion-application.xml before it gets deployed is as follows.
<namespace-access>
          <read-access>
               <namespace-resource root="">
                    <security-role-mapping>

Orion-application.xml gets overwriten when deploying with admin_client.jar

Hi,
I am trying to deploy an ear in OC4J 10.1.3.3.0. The ear contains a META-INF folder with a application.xml and a orion-application.xml files.
When running the admin-client command line, the deployment overwrittes the orion-application.xml file.
I really don't know how to solve this problem.
What else could I do?

Greetings,
The file orion-application.xml is an oc4j-specific file. If you do not create this yourself it will be created during deployment of your application.

Orion-application.xml location

Hi,
I am building an EAR file in JDeveloper 10.1.3.4 and then deploying it on 10G server. I need to add the orion-application.xml file to my EAR file. Where should I put it relatively to the home directory of my web application?
This file already exists on the server in application-deployments/<app_name> directory, however it was copied there manually.
thanks in advance

You have to put it in the META-INF of the EAR. The directory where the application.xml resides.

Setup meta-inf/orion-application.xml through jdeveloper

Hi,
I have a bc4j application. I don't want to use the default orion-application.xml file.
I created a new one and put that under a new folder named meta-inf.
In project properties, I created a new file groups named meta-inf and defined my new meta-inf folder.
when the project gets deployed, doesn't have my custom orion-application.xml file.
it is still using the default one.
Any idea?
thanks,
Setare

Hi,
you can only have one orion-application.xml in a project and it need to be in the specified location. You can change the default with your file, but this is what you can do.
If you don't believe, open the deployment profile of your application, which is the part creating teh WAR and EAR file, and add a new File Group pointing to this directory (note that the directory must be under the SRC folder of the project

Does user directory in oc4j requires entry in any XML files

Hi All,
I have created directory called "Sample".I have placed this directory inside web-apps in oc4j.Does this directory "Sample" requires any entry in the XML file.If so why???
Thanks & Regards,
Thirupathi.S

Hi, Adam
There are several ways that I can think of to accomplish what you want to do. The solution best fit for you depends on what you use to open a xml file.
1. If you use basic file I/O functions to read your xml files:
then you will need to use Search and Replace your xml string by using Regular Expression. If you do not know what it is, think of it as a advanced way to search within a text using wildcards. I really really recommend you to take some time to learn this as it helps your string manipulation in general.
For example, if you want to remove all the xml tags like "<abc>" or "</abc>, it can be easily done by using a Search and Replace String function:
In Search and Replace String node:
>>input string = your xml string
>>search string = "<[^>]*>" (do not include double quotes)
>>replace all? = True
(You may need to right click on the node and switch to 'Regular Expression' mode)
2. If you use xml parser, then it is simple enough just to use "Text" method of the XML object to extract all xml tags and get a string.
If you are using this option and have troubles doing it as you wish, let me know.
Thanks.

Env-entry-mapping in orion-application-client not available in JNDI lookup

I have an application client module in my EAR file that I've configured to auto-start.
It has a few env-entry defined in it's application-client.xml.
When I deploy the EAR file to OC4J 10.1.3, the application client module gets started and can access these env-entry properties from its JNDIContext.
Now, comes the problem. During the deployment process, I edit the Deployment Plan, and change the env-entry property values, and then deploy the application.
However, the application client module still gets the original values when it does the JNDI lookups of those env-entry names.
I have checked to see that OC4J creates an orion-application-client.xml during deployment and it shows the env-entry-mapping elements with the updated values.
Why is the JNDI lookup returning the values from application-client.xml and not the overriden values set in orion-application-client.xml?
I have tried this on OC4J 10.1.3, as well as 10.1.3.1.0 - got same behavior.
Is this a bug in OC4J? This seems to work fine with ejb modules, but not application client modules.
Thanks,
Kalpak

Avi!
Of course, I had tried it before I wrote the question. I put the modified xml file into the application area. After that AS restarts OC4J instance. And then I find my xml without any changes I made! I tried to do the same thing from the AS console. The same!

Stop boundless growth of myapp/application.xml

I've put an orion-application.xml in my EAR in META-INF, with the <log> tag commented out.
(if this is how you turn off creating the application.log ??)
I see this orion-application.xml file in home/applications but oc4j (9.0.2) seems to ignore
this deployed version and mfg's it's own an puts into home/application-deployments/myapp
Any thoughts?
BTW, I'm managing my own global log from the stdout/stderr from the VM.
I wouldn't fool with my tool that manages the stdout/stderr logging into my own log file and .bak
when it grows too big, if OC4J would do this for it's stdout/stderr and each application's logging
into application.log. A file that grows boundless has a few liabilities in my view. :)
Thanks, curt

Boundless growth of all the log files is a big deal for a 24x7 critical app!!
Bouncing the appserver just to clear the logs doesn't make sense, no?
Any help in sight? If so how we configure log rolling?
Thanks, curt

Application.xml - Unknown Assembly Tag

Hello:
Has anyone encountered the error:
05/11/18 10:01:39 Error instantiating application at ..... Unknown assembly tag in file:..... <library>
This happens when I start up the oc4j application server...
I am positive that it happens because of the following line in my application.xml file:
<library path="../bvp-web/WEB-INF/lib"/>
When I take that line out, the applicaiton starts up fine.
Does anyone have any thoughts as to why I am getting that error? Isn't <library> a tag that is expected to be in the application.xml file?
I need that line in there since my jsps refer to classes that are in that directory.
Thanks for your help.

<library> tag only applies to the orion-application.xml in META-INF/ of a j2ee application or the j2ee/home/config/application.xml, which is actually the orion-application.xml of the default application of oc4j.

How to include custom application.xml in JDev9i project

Can anybody explain to me how to include a custom application.xml file when deploying to an .ear file? I need to include application wide security roles, and I can't see where in Jev9i how to do this.
After searching this forum, I see that jdev9i can't include the orion-application.xml, but I want to include just the standard J2EE application.xml. Is this possible?
Thanks,
matt

The standard application.xml file unfortunately can't be customized in JDev 9.0.2. The reasons why this capability was left out of JDev 9.0.2 are same reasons why the other EAR-level XML files were excluded. The OTN thread
Re: Regarding 11i and E-business suite
has a summary of those reasons, which you've probably seen. We know this is an area in need of improvement and will be adding this functionality in the JDev 9.0.3 release. Until then, you'll have to go with a work-around like an Ant build file, batch file, Java application, or some other kind of script.
