[fcrepo-user] Installation Problems with existing Apache-Tomcat 7.0.23

Mon, 09 Jan 2012 03:09:25 -0800 

Hi,
I have some serious problems with the installation of Fedora Commons on an existing Apache-Tomcat 7.0.23. 


Our current configuration is an Apache httpd 2.2-Webserver  
communicating with Apache Tomcat 7.0.23 using mod_proxy and the ajp//  
protocol. The java version is

java version "1.6.0"
Java(TM) SE Runtime Environment (build pxa6460sr9fp2-20110625_01(SR9 FP2))

IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Linux amd64-64  
jvmxa6460sr9-20110624_85526 (JIT enabled, AOT enabled)

J9VM - 20110624_085526
JIT  - r9_20101028_17488ifx17
GC   - 20101027_AA)
JCL  - 20110530_01


I proceeded by using the manual installation and answering all the  
questions the installation script asked me. At a first glance, the  
installation seems to work fine, since the static web pages are served  
well. But the java servlet all fail.



Here is a simple test, using the script on the site /fop coming  
together with Fedora Commons:


http://ourhost.dom/fop/FOPServlet?source=http://www.fedora.info/services/fop/sample_fo.xml


returns a Tomcat error page. Note that the error is not caused by link  
rot (which is present, too, since  
http://www.fedora.info/services/fop/sample_fo.xml
does not exist any longer). The whole query string is interpreted in  
the wrong way and a file


/usr/local/apache-tomcat-7.0.23/conf/http:/www.fedora.info/services/fop/sample_fo.xml

is searched.


Are there some configurations that I should take to make the  
installation work?



I googled for snippets of the error message, but I found only a  
comment from May, essentially suggesting to downgrade Apache Tomcat to  
version 6.0.



P.S. I am aware of the fact, that I can get fop & Co. directly from  
apache.org and install them independently from Fedora Commons. But  
then, Fedora Commons still does not work properly, and there the cause  
may be harder to see.


P.P.S. Attached is the full error message from Apache Tomcat.
