[ http://issues.apache.org/jira/browse/AXIS-1261?page=comments#action_58834 ] Danielle Vella commented on AXIS-1261: --------------------------------------
I had the same issue with Axis 1.1. My problem disappeared when I started using Axis 1.2 RC2. Does anybody know what code change was made to get this to work? > engineConfigFactoryMissing (for concurrent requests) > ----------------------------------------------------- > > Key: AXIS-1261 > URL: http://issues.apache.org/jira/browse/AXIS-1261 > Project: Axis > Type: Bug > Components: Basic Architecture > Versions: 1.1 > Environment: Linux 2.4.20; Java 1.4.1; Tomcat 5.0.19; Axis 1.1 on Pentium4 + > 1Gb > Reporter: Philip Fletcher > > Bug logged at request of Davanum Srinivas: > To attempt to test concurrent performance of Axis (using > samples/userguide/example3), I have created two testing classes: TestThread > (extends Thread:) which calls samples.userguide.example3.Client.main( args ) > from it's run method and Test which simply starts 10 TestThread threads. > Occasionally (1 in 10) I will get a NullPointerException for the first 2-5 > threads often accompanied by: > org.apache.axis.configuration.EngineConfigurationFactoryFinder$1 run > SEVERE: Unable to locate a valid EngineConfigurationFactory > java.lang.NullPointerException > The error is generated from line 183 of EngineConfigurationFactoryFinder.java > where it has the following comments: > log.error(Messages.getMessage("engineConfigFactoryMissing")); > // we should be throwing an exception here, > // > // but again, requires more refactoring than we want to swallow > // at this point in time.
