object adapter requires configuration

[RonnieDay]

Hey,

I am trying to start my icegrid and keep getting the 'object adapter '{ServiceName} requires configuration' error message.

my application config is :

<?xml version="1.0" encoding="utf-8"?>

</application>
</icegrid>


I have looked in the icegrid admin gui and it appears that the service entry point paths are absolute ... and wrong!

i.e. C:\IceGrid\icebox\\helloService.dll:HelloServiceI (too many \\'s)

where does it pick this address up from?

I have tried changing the above application config to include an absolute address and it doesn't seem to filter through to the GUI.

Any help would be appreciated

Cheers

Ronnie

Hi Ronnie,

I am trying to start my icegrid and keep getting the 'object adapter '{ServiceName} requires configuration' error message.

This indicates a mismatch between the object adapter name in your code and the object adapter name in your configuration. It sounds like your code is using {ServiceName} as object adapter name, when you'd want something like "HelloBartServicegroup-Bart0". The implementation of createObjectAdapter does not perform any substitution on the name you provide.

I have looked in the icegrid admin gui and it appears that the service entry point paths are absolute ... and wrong!

i.e. C:\IceGrid\icebox\\helloService.dll:HelloServiceI (too many \\'s)

This is unrelated to the object adapter name mismatch above.

Where do you see this string with too many \\? In the generated configuration file? In the 'Live deployment' tab of the IceGrid Admin GUI?

Could you also post your actual IceGrid XML descriptor? The one in your first post does not use binPath for the entry value.

Cheers,
Bernard

Hey Bernard,

Sorry if I added confusion with the quotes. The error message does state the correct service group of "object adapter 'Hello-Bart0' requires configuration'. I placed the {ServiceName} comment in as it appears to occur with any service I create.

my descriptor config is as follows:

<?xml version="1.0" encoding="utf-8"?>
<icegrid>
<application name="HelloBartService">

</icegrid>

my node config is as follows:

IceGrid.Node.Data=c:\icegrid\icebox\db
Ice.Default.Locator=RonsReg/Locator:tcp -h LN7S9438 -p 50001


and my registry config is as follows:

#
# The IceGrid instance name.
#
IceGrid.InstanceName=RonsReg

#
# The IceGrid locator proxy.
#
Ice.Default.Locator=RonsReg/Locator:tcp -h LN7S9438 -p 50001

IceGrid.Registry.AdminSSLPermissionsVerifier=RonsR eg/NullSSLPermissionsVerifier

#

#
IceGridAdmin.Username=foo
IceGridAdmin.Password=bar

as for the too many "\\"s it appears only in the adminGUI as you can see from my config, the extra slash is not present for binPath

I fixed it!

it turns out there was a mismatch in names ...

in the config I was stating "HelloBartService-${name}"

however in the Service code I was using :

_adapter = communicator.createObjectAdapter("Hello-" + name);

therefore I simply changed it to :

_adapter = communicator.createObjectAdapter("HelloBartService-" + name);

and it worked.

Hi Ronnie,

as for the too many "\\"s it appears only in the adminGUI as you can see from my config, the extra slash is not present for binPath

This could be a small bug.

Keep in mind that in config files, backslash is the escape character. So '\\' in a config file is the encoding for a single '\'. This is fully documented here: http://www.zeroc.com/doc/Ice-3.4.1-I...ties.31.3.html

In config files, \ in front of most characters is preserved; the exceptions are '#', '=', '\' and whitespace.

Cheers,
Bernard
