[Geoserver-users] NullPointerException upon starting GeoServer 2.4.2 via Tomcat 7

GeoServer GeoServer User

Hello,
"FAIL - Application at context path /geoserver could not be started"
and the attached Tomcat log starts with:
java.lang.NullPointerException
  at
org.eclipse.xsd.impl.XSDSchemaImpl.reconcileAttributes(XSDSchemaImpl.java:2065)

catalina-16-23.out
<http://osgeo-org.1560.x6.nabble.com/file/n5094496/catalina-16-23.out&gt;

The war file was downloaded correctly and extracted by Tomcat. The file
permissions are correct.
Other applications work well under the same Tomcat 7.

Debian ("Jessie")
Tomcat 7.0.42

java version "1.7.0_21"
OpenJDK Runtime Environment (IcedTea 2.3.9) (7u21-2.3.9-5)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)

Any ideas?

Thanks for your attention,
Menashè

Menashè,

this may not be related anyhow, do you have the chance to use the standard Oracle JVM?
Cheers,
Carlo

Menashè,

do you have any other application deployed in the same tomcat instance?

Take also a look here:http://osgeo-org.1560.x6.nabble.com/Problem-parsing-GML-with-geotools-in-Jdeveloper-JDK-1-5-td4327418.html

Thanks Carlo. I've installed the latest Oracle JDK:
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

Yes, there are other deployed applications.
Actually, we've found a workaround: removing xmlparserv2.jar from
/usr/share/tomcat7/lib.
This library conflicts with geoserver and results with the exception that
can be found in the previously attached log file.
*xmlparserv2.jar *is a part of Oracle 12 database server. It's required by
one of the other web services in our Tomcat installation. Since this jar is
used by Tomcat already before loading the other web service, we cannot limit
it only to this service and avoiding the conflict. Already tried.
We have created a "thin" version of the jar which includes only the
following content, but we still see the above exception.

Any ideas?

Tree of the thin xmlparserv2.jar:
oracle/
oracle/xml/
oracle/xml/async/
oracle/xml/binxml/
oracle/xml/comp/
oracle/xml/fdom/
oracle/xml/fisupport/
oracle/xml/jaxp/
oracle/xml/jdwp/
oracle/xml/mesg/
oracle/xml/parser/
oracle/xml/parser/schema/
oracle/xml/parser/v2/
oracle/xml/scalable/
oracle/xml/util/
oracle/xml/xpath/
oracle/xml/xqxp/
oracle/xml/xqxp/datamodel/
oracle/xml/xqxp/functions/
oracle/xml/xqxp/functions/builtIns/
oracle/xml/xslt/
oracle/xml/xti/
org/
org/w3c/

Detailed version is attached. jar-tf-xmlparserv2.jar.txt
<http://osgeo-org.1560.x6.nabble.com/file/n5094704/jar-tf-xmlparserv2.jar.txt&gt;

Thanks,

Menashè,

geoserver ships many dependencies so you may encounter many other problem (at runtime) if you deploy it in the same container with other application.

Usually we suggest to configure multiple instances of tomcat to keep classloaders separated.

Alternatively you could try to use jboss which supports classloader isolation (http://geo-solutions.blogspot.it/2009/07/deploying-geoserver-on-jboss-as-5x.html).

Cheers,
Carlo

Carlo,
Thank you for the good advice.
Geoserver was tested mainly with Tomcat instead of Jboss or Resin, so we'll
have multiple instances of Tomcat as documented in Tomcat's RUNNING.txt.

Best regards,
Menashè

Just confirming that avoiding the compatibility problem using a separate
Tomcat instance resolves the problem.
