Setup of Deegree2 WPVS Demo on Ubuntu 9.04 (amd64)

Hello,

I tried to setup a deegree-WPVS on a 64Bit Ubuntu Linux environment and encountered some Problems with that. The thing that wondered me, was, that I first made this procedure on my Laptop, running Ubuntu 9.04 (but in 32Bit environment), and everything went fine without a problem.

On my 64Bit Desktop it gave me the following error (in catalina.out): 

[12:14:40] INFO: Reading configuration for WPVS from URL: 
'file:/usr/local/tomcat/temp/0-deegree-wpvs/WEB-INF/conf/wpvs/wpvs_configuration.xml'.

Caused by: java.lang.NoClassDefFoundError: sun/awt/Win32GraphicsDevice

 

It took me quite a while to realise, that the Win32GraphicsDevice is not supported in 64Bit Java.

So I decidet to use a 32Bit Version to try If it would fix the error. And it did!

So here is how I fixed it:

1. Install a 32 Bit Java JRE

apt-get install ia32-sun-java6-bin

 

2. Install 32-Bit Java3D into the 32Bit Java

2.1. Get the j3d-1_5_2-linux-i586.zip from https://java3d.dev.java.net/binary-builds.html

2.2. Install it to your 32Bit-Java Env.

unzip java3d-1_5_*.zip

cd java3d-1_5_*

unzip j3d-jre.zip

sudo cp lib/ext/* /usr/lib/jvm/ia32-java-6-sun/jre/lib/ext/

sudo cp lib/i386/* /usr/lib/jvm/ia32-java-6-sun/jre/lib/i386/

 

3. Install Tomcat according to my HowTo

-> http://www.christian-willmes.de/content/howto-tomcat6-ubuntu-804-strato-...

But link the JAVA_HOME variable to the 32Bit Java path in the init script. 

#!/bin/bash

export JAVA_HOME=/usr/lib/jvm/ia32-java-6-sun
export CATALINA_BASE=/usr/local/tomcat
export CATALINA_OPTS="-server -Xmx1024m"
case $1 in
start)
sh /usr/local/tomcat/bin/startup.sh
;;
stop)
sh /usr/local/tomcat/bin/shutdown.sh
;;
restart)
sh /usr/local/tomcat/bin/shutdown.sh
sh /usr/local/tomcat/bin/startup.sh
;;
esac
exit 0

 

4. Download the Deegree2 WPVS Demo

-> http://download.deegree.org/deegree2.2/deegree-wpvs_v2_2.zip

4.1. Unpak the .zip file

4.2. Deploy the deegree-wpvs.war into your tomcat Hope this helps some people to save some time.

Because this is one of these errors you can spent quite alot time on... like I did.
