I added/removed jars one by one.... of course it had to be the last one. When I removed /home/min/ucng/javaLibs/selenium-server-standalone-2.20.0.jar It started to work. However... I need selenium - it's my main browser. So when I added it back.... SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found binding in [jar:file:/home/min/ucng/javaLibs/pbapi-full-1.4.0.91/lib/test/slf4j-log4j12-1.6.1.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/home/min/ucng/javaLibs/selenium-server-standalone-2.20.0.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
Exception in thread "main" java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;Ljava/lang/Throwable;)V at org.apache.commons.logging.impl.SLF4JLocationAwareLog.debug(SLF4JLocationAwareLog.java:99) at org.apache.http.impl.conn.SingleClientConnManager.getConnection(SingleClientConnManager.java:212) at org.apache.http.impl.conn.SingleClientConnManager$1.getConnection(SingleClientConnManager.java:190) at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:401)
As the warning message above shows, selenium-server-standalone-2.20.0.jar contains an SLF4J binding. It also contains the classes of an *older* version of slf4j-api.jar. Which explains the NoSuchMethodError exception about org.slf4j.spi.LocationAwareLogger.log method.
Interestingly enough, selenium-server-standalone-2.21.0.jar released just a few hours ago does *not* bundle slf4j classes. Note: perhaps using a jar file which includes "standalone" in its name was the original error. (Disclaimer: I have never used selenium.)
