Admin console nullpointerexception

Hi all,
Thanks in advance for your help.
Just installed j2ee on a Mandrake 10.1 box, appserver8.2 runs, all sample apps run, the command line works, and i can get to the login page for the admin console. After I attempt to login, I"m forwarded to: http://localhost:4848/asadmin/admingui/TopFrameset, but the admin console shows a few frames all with same error text in them:
**********A "com.sun.enterprise.tools.guiframework.exception.FrameworkException" was caught. The message from the exception: "java.lang.reflect.InvocationTargetException while attempting to process a 'error' event for 'homePage'."
The root cause is "com.iplanet.jato.NavigationException: Exception encountered during forward"
See the HTML source for more detailed (stack trace) information.*********
The HTML source doesn't say anything.
I've uninstalled and reinstalled several times and even tried the new beta version, appserver9.
Anyone have any ideas what the problem might be?
thanks again

Don't know why, but the admin console won't open using Konqueror 3.2.0 web browser but would open using Epiphany 1.0.7 web browser. Sometimes i hate Linux systems.
Thanks for trying.

Admin Console Internal Server Error

Here's an unique issue I've observed in Weblogic 11g on Solaris 10.
Everytime I access the admin console after the admin server restart, I see the below error :
"500 Internal Server Error
The server encountered an unexpected condition which prevented it from fulfilling the request.
The best thing to do is start at the Home page or try the browser back button"
Also this issue occurs only when I've opened the admin console once before the restart. I have enabled onDemand deployment of Internal application. Does this have anything to do with the error ?
Thanks,
Jess

I looked at our restart script and saw its deleting files under the adminserver tmp Dir before starting up the server. Its deletes only files while the Directories under tmp are still remaining. I think thats what is causing the issue. I was able to resolve it by deleting the tmp Dir completely and starting up the server.

========================
p.s. error CR100006 was supposed to be fixed in SP2.

Strange Error... seems due to currpt installation.
Things to check:
- Start of instance: please check all processes are down before starting up AdminServer
- Start of instance: please check messages during startup (also Warnings...)
- Check listen address, listen IP of instance...are there other (managed) instances?
- Config files: check the <doman>/config.xml , compare it with backups if you got them

Hi
From the admin console ... Are you able to check the status of Node Manager ?
If yes ... please check the SSL configuration of managed servers ...
Check the domain administration port also.

Org Chart 3.0 : Admin Console Error

Hi
Version: Org Chart 3.0
In AdminConfig->ORgChart->Hierarchies->Position, the pforile step (after Details Designer)
has an yellow triangle. When I move my mouser over, it says:
An errror has occured when initializing this step: java.lang.NullPointerException:while trying to
invole the method com.nakisa.framework.configuration.detailsPresentationConfiguration.toXML() of an
object loaded from a local variable.
Therefore, I can never go into the Profile step.
Has anyone seen this error before?
Thanks.

Can you list your build version (from front page of Admin Console) plus which OS you are on and which version of NW CE you installed (7.1 or 7..2)?
I have never seen the error. I am sat in front of 3.0 OrgChart Admin console right now and don't get the error.

Admin Console Integration for Users in a Custom Realm

We are implementing a custom realm and are having troubles getting our Users to
show up in the User list.
Our user class extends weblogic.security.acl.User, and is forced to use the default
CTOR because our data access layer requires it.
Unfortunately, getName() returns null if the User(String) constructor is not used.
Furthermore, Identity::setName() is final, so it seems as though there is no
way to set the user's name after construction.
I am correct in this?
If so, any thoughts on whether it is worth going down the path of making my user
class implement Principal instead of extending weblogic.security.acl.User? I
would be forced to try to guess at what methods in User are required to integrate
with the admin console, I believe. I have not been able to find any documentation
that specifies what api/contract the console uses when it attempts to display
user, role, acl information for a custom realm.
Any advice would be greatly appreciated.

I am correct in this?Yes. Changing a user's name on a constructed user object is like mutating that
user to another user - a security hole. It isn't allowed.

weblogic.security.acl.CredentialChanger, so you can change passwords through the
console (otherwise you get NullPointerExceptions).
You really want to get around not being able to supply a user name as part of
the ctor.

-chris1. Your realm should extend AbstractManageableRealm and implement DebuggableRealm
if you want to integrate with the console.
2. The only contract is to implement all the methods!
3. Check the type of the user and group objects being passed to your realm - if
they're not your user and group type, reject the call.
4. The documentation is indeed terrible, and often wrong. The examples shipped
are incomplete (the RBDMS realm shipped has approx 1/3 of the functionality).
You'll get good with jad.
Should all be better in 7.0 with JAAS. The realm interfaces is a dog.
Good luck,
simon.

Error in creating a new user in j2ee 14 admin console

Hi,
I am getting the following error while trying to create a new user using the j2ee 1.4 admin console.:
A "com.sun.enterprise.tools.guiframework.exception.FrameworkError" was caught. The message from the exception: "Unable to get View for ViewDescriptor 'fileUsers'"
The root cause is "java.lang.ArrayIndexOutOfBoundsException: 0"
Plz proide me with solutions
Regads,

This problem wil happen only if you've created a user with an empty group id, and this issue is fixed for FCS .
You have two workarounds to use adminGUI for managing users:
1. Use CLI, and create a group id to this user, then you can use adminGUI.
2. Other option is remove the empty group id user from domain.xml, and then you can come back to adminGUI to create the user with some group id. I prefer the 1st option.

How do I create admin console users with full access to configuration and the directory in every instance?

I want to be able to create directory user ID for the iPlanet administrators. They should be able to access the admin console and all the instances created. They should be able to configure each instance and directory. I was able tocreate Admin Server Administrators but they were only able to modify the directory(tab) and not the configurations(tab). Any help would be greatly appreciated!
Thanks.
Keith

Hi Keith,
In o=netscaperoot, edit the static group called cn=Configuration Administrators, ou=Groups, ou=TopologyManagement, o=NetscapeRoot - this group contains the admins peer to your config admin. Since the console is quirky and doesn't let you add in users not in netscaperoot, just click advanced and put in the full dn of whoever you want in by hand, e.g., uid=scarter, ou=people, dc=mydomain,dc=com as a static member. then rebind to the console with the full dn and passwd, and away you go :)

Read Only Admin Console

Hey,
Has anyone found a way to add further restrictions to users logged in to the Admin Console based on membership to a Group? Restricting them to specific Menu Items is taken care of, but I'd like to be able to prevent them from editing anything in the Manage Users section.
Ideally they would be able to view the user details page and user resources, but not be able to change them in any way. At the same time I'd like to filter out certain user fields from displaying (for instance, the person's SSN).
Is there any way to do this outside of front-end customization? This is using OIM 9.1.0.0.

If I understood your qurey correctly... try changing the property of the user filed in FormMetaData.xml to readonly. By this you just display the fileds but are not editable.

Hi Team Admin console not connecting

Hi Team,
I am using sccm2007 sp2 in one of the primary. I am unable to connect admin console getting attached error. Actually one of my team met did the repository rename.. Is it cause issue? if yes. how can i back the track

Previously i able to connect the sccm primary console. now i am not. I checked permission vise everything good..
So that i capture my adminui.log ..
one of my team met done the repository rename in primary server. My question that's y i am not able to connect the sccm server. when i tried to connect in WMI root\sms_sitecode getting error.. can you understand now? or not
There is no getting back the WMI namespace if it was renamed or delete. It is not supported to do this without contact CSS directly for support.
You have two options, Attempt to clean up the mess of renaming the WMI. This might take a while due to the complexity of WMI and the unknowns of what was exactly done.
Call CSS and tell them what exact you have done and get them to work with you to solve this problem.

Can't access to Portal Admin Console.

Hi all,
I'm working with WLP 10.2. I've created the ear-file (using maven) and deployed it on server (with Unix-system). The current application works well.
My current task is a creation portal in streaming mode. Unfortunately I can't access to Portal Admin console for resolving task. I always retrieve "Error 404 (Not found)".
As I know the admin-tools.war is responsible for Portal Admin Console. I've checked admin-tools.war is running on server (with status "Active").
I'm using the next path for running Portal Admin Console: {serverhost:port}/{context root of admin-tools}/portal.portal.
Maybe, Should I set up(correct) application.xml or weblogic.xml?
Please let me know if you have any ideas.
Thanks,
Yuriy

I think your URL is wrong, try with the following...
http://{server:port}/{name_your_ear}Admin/portal.portal
name_your_ear= The name of your Enterprise Application.
For example,
http://localhost:7001/DemosEarAdmin/portal.portal
I hope this helps

Can I use Admin Console to Start Clustered Servers ?

          I have just started to look at clustering and am in the process of running through
          the cluster example tutorial. I have used the domain config wizard to create
          a manged server with a cluster and another server to act as the http proxy. As
          I prefer to use the admin console for all tasks I wondered if there is any way
          to start the managed servers from the console. The reason I ask is that I cannot
          find a way to start another server from the console apart from the admin server.
          On a seperate note can anyone tell me whether the multicast IP address is something
          that I should be concerned with as a developer. The reason I ask is that I know
          it is used for clustered servers to communicate, but how can it do that if the
          IP address is a physical box that does not have BEA installed.
          Thanks
          Justin


Yes, you can start all managed servers from the console ... Look under the
          cluser that you create and click on the control tab ... you should be able
          to start all the managed servers that will be apart of the cluster there.
          Weblogic uses a service on the local machine called node manager which will
          start and stop the services on each managed server.
          Its good for developers to know something about multicasting as far as what
          it does, how it works but most system administrators all well versed with
          the inner workings of it. You have to have weblogic installed in order for
          that particular box to become apart of the cluster, and you can run multiple
          managed servers on one physical box but be careful with resource intensive
          apps.

Unable to open Messaging Server 6.2 through admin console 5.2

my system is
Sun Java(tm) System Messaging Server 6.2-3.05 (built Nov 23 2005)
libimta.dll 6.2-3.05 (built 02:22:19, Nov 23 2005)
Microsoft Windows 2000 version 5.2 (Build 3790)
i installed Sun Java Enterprise System (directory, admin, messaging) servers on my windows 2003 server, all is working fine except:
1- unable to open my messaging server through my admin console 5.2.
when checking the error log file i see
"[05/Jun/2006:10:51:49] failure ( 2624): for host t.est.hotmail.com trying to GET /msg-config/tasks/operation/cgi_root, cgi_scan_headers reports: the CGI program E:\Sun\Server-Root\bin\msg\admin\bin\cgi_root.exe did not produce a valid header (program terminated without a valid CGI header. Check for core dump or other abnormal termination)"
Any clue?
2- When creating a new user through the admin console 5.2, and check the mail account checkbox, i don't get the "mail tab" to complete the needed information, and therefore the newly created user is not an active email account as mainly the mailhost attribute has not been created for the account
Is this related to the problem in point 1?
NOTE 1: i ran cmm_dssetup.pl before configuring the messaging server and selected schema 1
NOTE 2: i downloaded the software from sun.com, didn't register it yet as i'm in the testing phase
Appreciate your help, direction and tips

Oh, my.....
1. The Directory Console is not very useful, for anything in Messaging 6. The MTA is configured via editing files, and the mail store is better configured using the configutil utility.
2. You SHOULD NOT attempt to create users with the Directory Console. They won't work. Use either the command-line tools provided (comm-admin), or use the Delegated Admin tool provided.
