Re: Deploying Activiti Explorer - NullPointer exception

vasile_dirla — Mon, 03 Aug 2015 08:33:54 GMT

What version of Activiti are you using?

(Also make sure the H2 server is up and running on the default port.)

If this is doesn't help please provide step by step what are you doing in order to reproduce it.

Re: Deploying Activiti Explorer - NullPointer exception

ncoonghe — Mon, 03 Aug 2015 23:06:23 GMT

I am using activiti-5.17.0. I just dropped the activiti-explorer.war under webapps in tomcat
Changed the DB properties to have the below entries and started tomcat.

db=h2
jdbc.driver=org.h2.Driver
jdbc.url=jdbc:h2:tcp://localhost/activiti
jdbc.username=sa
jdbc.password=

Although the exception comes on start up ….things seem to work. But I do not like the exception to be shown in the log. It does not happen if I use the in memory version of the DB. Only after I changed the jdbc URL to jdbc.url=jdbc:h2:tcp://localhost/activiti I see it happening

Also I run H2 as below

C:\Program Files (x86)\H2\bin>java -cp h2-1.3.176.jar org.h2.tools.Server
TCP server running at tcp://130.110.217.110:9092 (only local connections)
PG server running at pg://130.110.217.110:5435 (only local connections)
Web Console server running at http://130.110.217.110:8082 (only local connections)

Sometimes the entire stack is not printed in the log just the NullPointerException, other times the whole stack is printed..

Re: Deploying Activiti Explorer - NullPointer exception

Hi,

I'm also experiencing same NullPointerException every time I restart the tomcat.
Activiti Version 5.20.0
Tomcat Version: 7.0.53
JDK: 1.8.0_65
Operating System: OS X 10.10.5
DB: mysql Ver 14.14 Distrib 5.6.29, for osx10.8 (x86_64)

Though this error (NPE) doesn't have any functional impact on the activiti-explorer or activiti-rest operations still it's going to be a concern if the project has to be moved to Production. Kindly assist/guide on this error to avoid any risk factor it could bring post production.

Re: Deploying Activiti Explorer - NullPointer exception

This is the Tomcat session serialization failing cause some bits are not serializable …
One quick fix is to disable session serialization on Tomcat.
