Error while starting Tomcat

Hi everyone,

I'm getting this message in my localhost.log when I try to start Tomcat:

28-Jul-2018 18:54:41.886 SEVERE [localhost-startStop-1] org.apache.catalina.core.StandardContext.filterStart Exception starting filter sakai.request

java.lang.NullPointerException

at org.sakaiproject.util.RequestFilter.init(RequestFilter.java:664)

at org.apache....... etc

I checked RequestFilter on line 664 and found:

appUrl = serverConfigurationService.getString("serverUrl", null);

Then configured this on my sakai.properties

serverUrl=http://localhost:9090

but I'm still getting the same error. Any clues about what this could be?

Thank you!

PD1: Java 8, Tomcat 8, Maven 3.5.4.

PD2: I'm trying to run this in the master branch. It is supposed to run, right? Otherwise, what are the branches/tags that are supposed to run?

Best Regards,
Sergio Muriel

Hi Sergio,

Did you restart after making that change? Are you sure it's the correct sakai.properties that Tomcat is looking at?

Regards

Steve

Is the machine's firewall allowing something to open on that port?

Or some other process could already be using 9090.

Check what else is running.

If the NullPointer is in the line that Sergio quoted, then it's the
serverConfigurationService that is null, i.e. something went wrong with the
bean injection.
Is there some other error in the catalina.[out|log|whatever]?

I'm pretty sure. I only have one at CATALINA_HOME\sakai\sakai.properties

Should I look somewhere else?

James:

I checked with "netstat -an" command (Windows) but it doesn't show anything on 9090.

Nothing really. What is more I emptied my Tomcat, put only one page on it and it ran perfectly.

Something like: http://localhost:9090/example/index.html

I'm getting a bunch but this is the first one thrown. It writes the first SEVERE on catalina.log when the first NullPointerException happens in RequestFilter.java:664. Date, time and millisecond match: 30-Jul-2018 16:23:33.975

Just in case I attached the log files. Here are the highlights:
