WAR deploy fails to start

Setting up a new server and got a new error I've never seen before. It keeps the WAR from starting.
CentOS 7 (running in Docker)
Java 1.8.0_101

Hi Scott

Cant answer the specific question but had similar issues with the war starting, managed to fix it with this ..

#TestFile
FROM tomcat:8.0
MAINTAINER Gordon McLean <Gordon@Clickdigital.com>
COPY war /usr/local/tomcat/webapps
CMD ["catalina.sh", "run"]
VOLUME /velocity
EXPOSE 8080

It appeared that you have to specifically start catalina with CMD ["catalina.sh", "run"]

I have deployed this to Amazon AWS via Docker Cloud I will share what I did on GitHub shortly

Best
Gordon

which servoy version is this?

Version 8.0.3


I have done several other Docker deployment too, but just problems with this one.

ah then the line number makes sense (there are quite some changes in that area already to 812rc)

but it is on a weird line, don't you have any exceptions in front of that? Because something is not started (our internal application server instance) that should already be up and running by then for a long time
I guess multiply things don't work? like the admin pages?

Yes, nothing works. the war unzips, but nothing seems to be listening. Directory /usr/share/tomcat/.servoy is also empty. Doesn't seem like it gets very far.

also nothing in the tomcat logs? Because it seems to me that the WarClientServletContextListener that is or should be hit the first is not working correctly

So..I'm back trying to get this working on this same server again. This time I've updated to 8.1.2 .

So I have:
Servoy: 8.1.2 - build 3031
Java: 1.8.0_101-b13
OS: CentOS Linux release 7.3.1611 (Core)
Docker: 1.12.6

I get this error after uploading the war. It unzips, but fails to start.

So, I'm guessing the problem is somewhere in here:

no that is in the destroy again (because it can't init)
so that is just a result of the failure not the failure it self

problem is in

java.lang.NullPointerException
at com.servoy.j2db.server.ngclient.NGClientEntryFilter.init(NGClientEntryFilter.java:122)

that is this line in servoy:

ApplicationServerRegistry.getServiceRegistry().registerService(IMessagesRecorder.class, new MessageRecorder());

The problem is then that that is again also a result of something that goes wrong before that..
because getServiceRegistry() returns null here. That shouldn't happen

Before that Filter.init() is called the WarClientServletContextListener should be executed first that should bring up the whole application server..

So i really don't understand why the ContextListener is not executed or that you don't see a exception coming from that
See the web.xml in the WEB-INF dir of the war that you have:


<listener>
<listener-class>com.servoy.j2db.server.servlets.WarClientServletContextListener</listener-class>
</listener>

that listener should be executed before anything.. Thats how we start servoy app server.

Edit:
now i see that it is called or touched (because in the on destroy we do see that specific class)
But are you really not seeing any error where you see this in the stacktrace:

com.servoy.j2db.server.servlets.WarClientServletContextListener.contextInitialized(xxxx)

I pasted in the whole log. Is there anything else I can do to get you more info?

of every log file that you could find? So all tomcat logging but also the servoy log file? (i guess thats not really created yet)

i can't do anything with this. because it seems that something fails or really isn't configured correctly like SERVOY_HOME ?

Hi

I have the same problem. I'm just trying to set up WAR-Deployment with ANT/Jenkis for fun. So there's no hurry.

On a remote VM I get also this

java.lang.NullPointerException
at com.servoy.j2db.server.ngclient.NGClientEntryFilter.init(NGClientEntryFilter.java:122)

I tried it on a local tomcat (not the application-server of the developer, it a separate installation running on localhost:8888) and the WAR-file is running correctly.

Looks like there could be a configuration issue on the remote VM. What did you mean with SERVOY_HOME? The only configuration I did on the tomcat server was to set an admin-role and to liften up the max-upload-size. Is there anything more to do? E.g. read or writing rights for servoy?

Thanks a lot

Gregory

that the same thing, there has to be exceptions before that, if you get an exception there on NGClientEntryFilter then it is because the application server of servoy itself didn't start up fully

Hi Johann

:oops: !!!! I made a post how I solved it in my case. Who is interested, please check PAGE 2!!! on the bottom of this forum. Unbelievable. America first, Gregory second! :oops:

You where right!
I didn't found an exception in the log. But after a while I checked catalina.out file. There it was!

'Coudn't create server properties file in user home: usr/share/tomcat7 directory. Please set SERVOY_USER_HOME variable ......'

Thanks a lot

I will do that next week. It's enough for today.

Greetings Gregory

yes thats the biggest problem, i have also a feeling that Scott has a simular thing.

Maybe we need to fail a bit harder then (so the whole context doesn't come up). Problem is that we can't log like we normally do because almost nothing is initialized correctly.
