[GeoNetwork-users] TransformerFactory problem with GN 2.4.2 and Tomcat 6.0.18

Herbert_David_J · February 5, 2010, 10:07am

Hello,

I have successfully installed GN 2.4.2 on a Linux server running in Tomcat 6.0.18 container with PostgreSQL database. I am, for reasons connected with other webapps running in the same container, running my own copy of Geoserver - I have changed Intermap's mapServers.xml file to reflect this. On a fresh restart of Tomcat, GN behaves perfectly - I can log in as administrator, save metadata, and do everything I would expect. The logs (geonetwork.log and catalina.out) show no errors.

However, after a period of time (not sure how long but measured in hours) with no GN activity (but activity of other web apps in the same container, including Geoserver), even requesting the home page hangs. Trying again does at least produce some output but only to say "Requested operation could not be performed" and "NullPointerException". This can be reliably demonstrated by doing a fresh restart last thing before I go home, and then requesting the home page first thing when I return in the morning. Looking at the logs, I see this kind of thing:

The first failure is at the line about TransformerFactory. I have read that this message may mean that GN is trying to use the Xalan XSLT processor rather than Saxon. I have changed the file javax.xml.transform.TransformerFactory in geonetwork/web/geonetwork/WEB-INF/classes/META-INF/services to contain net.sf.saxon.TransformerFactoryImpl rather than the original value (which wasn't Xalan either, and gave the same problems). I've changed the equivalent file for Intermap too, cleared out all the Catalina work directories and restarted Tomcat a number of times, but I still get the same behaviour.

I am at a loss to interpret this behaviour, as I can't see what could have changed to provoke it. Once GN is in this state there is no way I can make it work again except by restarting Tomcat.

Java options are:

-Djava.awt.headless=true -server -Xms1000m -Xmx1000m -Xss64m -d64 -Dfile.encoding=UTF-8

JVM is

Java(TM) SE Runtime Environment (build 1.6.0_05-b13)
BEA JRockit(R) (build R27.6.0-50_o-100423-1.6.0_05-20080626-2104-linux-x86_64, compiled mode)

Thanks in advance for any insight on this one!

GN 2.4.2 and Tomcat 6.0.18

I am, for reasons connected with other webapps running in the
same container, running my own copy of Geoserver [...]

A quick guess is that exactly this leads to your problems. I had the same setup and as far as I remember at some stage GeoServer sets some global Java properties, which override the GeoNetwork ones regarding the XSLT processor.

This can happen after both servlets ran for some time, so it was pretty hard to find out.

Try disabling GeoServer for a while. My solution for that problem was to setup two Tomcat instances and run the servlets separately:

https://www.seegrid.csiro.au/twiki/bin/view/Infosrvices/GeoNetworkSetup#Create_second_tomcat_running_wit

Let me know, if that could be the problem.

Cheers,

Hi David,

In fact GeoNetwork 2.4 is set up to use Saxon (not xalan) - GeoNetwork uses the services API to set the transformer factory to saxon (actually to a caching xslt transformer on top of saxon) - which is probably the friendliest way to do this in that it doesn't affect other apps running in the same container that may want to use a different transformer factory.

I have heard that apparently a component of GeoServer is forcing the transformer factory to xalan using a system property which will break apps in the same container that don't use xalan - hence the problems that you are seeing. I didn't find this behaviour but I'll get in touch with the developer who did to see what else (apart from splitting the apps into separate containers) can be done to avoid this.

Cheers,
Simon

Hello,

I have successfully installed GN 2.4.2 on a Linux server running in Tomcat 6.0.18 container with PostgreSQL database. I am, for reasons connected with other webapps running in the same container, running my own copy of Geoserver - I have changed Intermap's mapServers.xml file to reflect this. On a fresh restart of Tomcat, GN behaves perfectly - I can log in as administrator, save metadata, and do everything I would expect. The logs (geonetwork.log and catalina.out) show no errors.

However, after a period of time (not sure how long but measured in hours) with no GN activity (but activity of other web apps in the same container, including Geoserver), even requesting the home page hangs. Trying again does at least produce some output but only to say "Requested operation could not be performed" and "NullPointerException". This can be reliably demonstrated by doing a fresh restart last thing before I go home, and then requesting the home page first thing when I return in the morning. Looking at the logs, I see this kind of thing:

The first failure is at the line about TransformerFactory. I have read that this message may mean that GN is trying to use the Xalan XSLT processor rather than Saxon. I have changed the file javax.xml.transform.TransformerFactory in geonetwork/web/geonetwork/WEB-INF/classes/META-INF/services to contain net.sf.saxon.TransformerFactoryImpl rather than the original value (which wasn't Xalan either, and gave the same problems). I've changed the equivalent file for Intermap too, cleared out all the Catalina work directories and restarted Tomcat a number of times, but I still get the same behaviour.

I am at a loss to interpret this behaviour, as I can't see what could have changed to provoke it. Once GN is in this state there is no way I can make it work again except by restarting Tomcat.

Java options are:

-Djava.awt.headless=true -server -Xms1000m -Xmx1000m -Xss64m -d64 -Dfile.encoding=UTF-8

Hi David,

As per Simon's email, I had a similar problem using an old release of
geoserver (1.5.3) installed with the BlueNetMEST. I turned the wfs
server on and this problem started occurring after making a wfs
GetFeature request.

I tracked this issue down to gml2 support in geoserver (the only support
for geoserver 1.5.3). In particular, as per Simon's email, when
generating a GetFeature response using gml 2, geoserver was setting the
transformer factory to xalan by setting
javax.xml.transform.TransformerFactory in System properties (see
org.vfny.geoserver.wfs.responses.GML2FeatureResponseDelegate). System
property settings are used in preference to services api setting.

I fixed my issue by upgrading to geoserver 1.7.3 (as per geonetwork
trunk). Geoserver 1.7.3 returns gml 3 by default which doesn't have
this issue. However, I checked the gml2 code in geoserver 1.7.3 and
geoserver 2.0 and it still sets javax.xml.transform.TransformerFactory
using System properties so if you are using gml2 for any reason by
requesting an earlier version GetFeature response where this is
returned, it will probably still break geonetwork.

Cheers,

Hi David,

In fact GeoNetwork 2.4 is set up to use Saxon (not xalan) - GeoNetwork uses the services API to set the transformer factory to saxon (actually to a caching xslt transformer on top of saxon) - which is probably the friendliest way to do this in that it doesn't affect other apps running in the same container that may want to use a different transformer factory.

I have heard that apparently a component of GeoServer is forcing the transformer factory to xalan using a system property which will break apps in the same container that don't use xalan - hence the problems that you are seeing. I didn't find this behaviour but I'll get in touch with the developer who did to see what else (apart from splitting the apps into separate containers) can be done to avoid this.

Cheers,
Simon

Subject: [GeoNetwork-users] TransformerFactory problem with GN 2.4.2 and Tomcat 6.0.18

Hello,

I have successfully installed GN 2.4.2 on a Linux server running in Tomcat 6.0.18 container with PostgreSQL database. I am, for reasons connected with other webapps running in the same container, running my own copy of Geoserver - I have changed Intermap's mapServers.xml file to reflect this. On a fresh restart of Tomcat, GN behaves perfectly - I can log in as administrator, save metadata, and do everything I would expect. The logs (geonetwork.log and catalina.out) show no errors.

However, after a period of time (not sure how long but measured in hours) with no GN activity (but activity of other web apps in the same container, including Geoserver), even requesting the home page hangs. Trying again does at least produce some output but only to say "Requested operation could not be performed" and "NullPointerException". This can be reliably demonstrated by doing a fresh restart last thing before I go home, and then requesting the home page first thing when I return in the morning. Looking at the logs, I see this kind of thing:
