Re: WO5.4 Web Services - Application not responding

Hi David,

To make sure of this I ran sample self contained WO 5.4 WebObjects Hello World Application and didnt get any issue accessing the same.

Thread dump while accessing the web service application. WorkerThreads are "waiting for monitor entry" per this.

Full thread dump Java HotSpot(TM) Server VM (1.5.0_13-121 mixed mode):

Just a guess, but could it be a firewall issue on that box? The thread dump looks like it is sitting there waiting for action.

Hi,

I have created a webobjects web service application using WO5.4 frameworks.
I deployed on my dev box (Mac OS X Server 10.4.8 (8N1215) / Xserve Intel/2 Dual-Core x 2 GHz/8 GB) with WO version 5.4 and working fine.

I placed same build on my prod server (Mac OS X Server 10.4.11 (8S2169) / Mac Intel/1 Quad-Core x 2.8 GHz/8 GB) it deploys the application, registers service without any error, but application / service is not accessible.
I put some directAction to check if App is accessible and that as well doesn't respond.
Overridden life-cycle methods in Application but the request doesn't even enter awake.

Moreover it creates CLOSE_WAIT for every request.

I have tried deploying application in following ways :

1. Have WO5.4 frameworks (.framework) in separate LOCALROOT/System/Library/Frameworks and made MacOSClassPath point these. Custom jars are placed in LOCALROOT/Library/Java/Extensions.
MacOSClassPath just has entries for these frameworks and custom jars. On startup I can see its reading only these paths and none other (like /System/Library/Java or network/Library/Java etc). This approach works for me in DEV box.

2. Made build (.woa) self contained and placed WO 5.4.2 and custom jars in APPROOT/Contents/Extensions. Here MacOSClassPath has entries for only JavaVM frameworks and application jar.
APPROOT/Resources/Java/marketingdatacaptureservices.jar
WOROOT/Library/Frameworks/JavaVM.framework/Classes/classes.jar
WOROOT/Library/Frameworks/JavaVM.framework/Classes/ui.jar
On startup I can see its reading only APPROOT/Contents/Extensions jars and above 3 entries of MacOSClassPath

With both approaches application comes up cleanly, but when tried to hit the directAction or make a service call there is no response, closewait is created and message "No instance available" comes up.

Also locally (on 10.5.4) with WO5.4 installed I always get this app up and service / directAction accessible.

Got jstack for the instance but not able to interpret any useful information from it. Attaching the same for reference.
<jstack.txt>

Please help !!!

Thanks & regards,
