Issue/Introduction
Endevor Tomcat/Web Services had been up and operational for several weeks. After recycled Tomcat/Web Services this past weekend found following error in Tomcat STC (WSTOMSTC) log and WSEWSSTC is not being spawned:
SEVERE: Exception sending context initialized event to listener instance of class [com.ca.mfaas.eurekaservice.RestDiscoveryListener]
java.util.MissingResourceException: Can't find resource for bundle java.util.PropertyResourceBundle, key eureka.name
at java.util.ResourceBundle.getObject(ResourceBundle.java:461)
at java.util.ResourceBundle.getString(ResourceBundle.java:418)
at com.ca.mfaas.eurekaservice.RestDiscoveryListener.initializeApplicationInfoManager(RestDiscoveryListener.java:36)
Environment
Release : 18.0
Component : CA Endevor Software Change Manager
Cause
1. When Tomcat starts, it will deploy EndevorService.war into its own directory /tomcat/webapps/EndevorService/
2. After that Web Services are being initialized, which means two listeners will be executed.
3. First Web Services Listener InitialServiceSetupListener, which will update file eureka-client.properties with values from enws.properties
4. Then mfaas listener RestDiscoveryListener, which reads eureka-client.properties and load all the properties from that bundle.
From the Tomcat job log:
[INFO] Endevor Webservice properties file found: /cai/CADeploy/ESCM/tpv/tomcat/webapps/endevor/enws.properties <- InitialServiceSetupListener
[INFO] Updating eureka-client.properties <- InitialServiceSetupListener
[WARN] No URLs will be polled as dynamic configuration sources.
[INFO] To enable URLs as dynamic configuration sources, define System property archaius.configurationSource.additionalUrls or make config.properties available on classpath.
[INFO] DynamicPropertyFactory is initialized with configuration sources: .config.ConcurrentCompositeConfiguration
[INFO] Loaded properties file file:/cai/CADeploy/ESCM/tpv/tomcat/webapps/EndevorService/WEB-INF/classes/eureka-client.properties <- RestDiscoveryListener
And here is error:
SEVERE: Exception sending context initialized event to listener instance of class [com.ca.mfaas.eurekaservice.RestDiscoveryListener]
java.util.MissingResourceException: Can't find resource for bundle java.util.PropertyResourceBundle, key eureka.name
at java.util.ResourceBundle.getObject(ResourceBundle.java:461)
at java.util.ResourceBundle.getString(ResourceBundle.java:418)
at com.ca.mfaas.eurekaservice.RestDiscoveryListener.initializeApplicationInfoManager(RestDiscoveryListener.java:36)
The code in that line is trying to do something like this:
private static ResourceBundle
String serviceId = eurekaPrope
This means, that it loads the bundle from class path, which should be /cai/CADeploy/ESCM/tpv/tomcat/webapps/EndevorService/WEB-INF/
Then it tries to get eureka.name from it. And that's where it fails and gives the first error with missing key.
Resolution
The file /cai/CADeploy/ESCM/tpv/tomcat/webapps/EndevorService/WEB-INF/classes/eureka-client.properties is empty (possibly due to IPL).
After copy eureka-client.properties from a backup and recycled Tomcat, Tomcat is up and running.
Alternative options if backup of eureka-client.properties is not available:
1. Stop Tomcat
Rename or delete /cai/CADeploy/ESCM/tpv/tomcat/webapps/endevor/enws.properties
Rename or delete /cai/CADeploy/ESCM/tpv/tomcat/webapps/EndevorService
Restart Tomcat
That should create new tomcat/webapps/EndevorService at runtime with new/default eureka-client.properties file
2. After trying option #1, if Tomcat still fails with the same error exception:
If have enough space, rename /cai/CADeploy/ESCM/tpv/tomcat to /cai/CADeploy/ESCM/tpv/tomcat_bk. Otherwise delete that directory but first backup any customised files (ENDEVOR.cfg, server.xml) for use during the reinstall process.
Then reinstall web service by running ENWSIns.sh (Endevor® 18.0 > Installing > How to Enable Web Services > Install and Set Up Web Services)
During the installation when prompted for:
CLEAN_ENDEVOR_TOMCAT_INSTANCE yes or no
Enter yes
