OK, I will create two issues, but the patches will probably not be
created until I'm back in Norway. I'm going to Spain next week and will
work with completely different things the next two weeks.
BTW, the Resin issue is quite funny. The CSS file is loaded if I use
Safari. It does not work on Firefox if ManifoldCF is deployed on Resin.
It seems that everything works, except I cannot start a new job, perhaps
because I have forgot to start a particular agent. I'm getting this error:
Error communicating with Ingestion API: Connection refused

Since the DBInterfacePostgreSQL class is responsible for any remote
communication, I would make those parameters local to the postgresql
implementation. So the parameters would be something like:
org.apache.manifoldcf.postgresql.hostname
org.apache.manifoldcf.postgresql.ssl
or some such. Then, you'd want to load the necessary parameters in
DBInterfacePostgreSQL.java itself. (I wouldn't bother with MySQL
since that's not officially supported at this time.)
The only problem I see is that the constructor architecture of
Database.java may make it a challenge to load the appropriate
parameters in the DBInterfacePostgreSQL constructor. But I think you
could make it work, and if not, we should probably fix this anyway to
make it easier.
Thanks,
Karl

You're right! I didn't read the command section in the documentation
properly. ManifoldCF does also run on Resin now. The only problem with Resin
is that the necessary resources, such as CSS, are not loaded. All the other
errors have disappeared, which means that it should be possible to run the
application on Resin.
Do you think I should create a ticket about running an external PostgreSQL
database as well? I think I know which classes to modify. I see there are
classes for MySQL as well, so perhaps the issue should be generally, i.e.
not PG specific.
I was thinking about extending the property list like this:
org.apache.manifoldcf.database.hostname (not required, defaults to
localhost)
org.apache.manifoldcf.database.ssl (not required, defaults to false)
For PostgreSQL I think it should be quite easy to implement this, but I'm
not sure when it comes to MySQL. Haven't touched that database system for
years.

Ok, have you followed the instructions for a multi-process
installation in how-to-build-and-deploy.html?
You will need to create the database (using DBCreate), and install the
schema (using Install), and register the crawler agent (using
Register). You will also need to create the properties.xml and
logging.ini files by hand.
Let me know if this helps.

I guess the problem is that the database does not exist. When I installed
it
on Tomcat, I got an error message telling me that the schema TEST does
not
exist. I tried to build the database with the username and password
"test"
by the following command:
./processes/script/executecommand.sh org.apache.manifoldcf.core.DBCreate
test test
And I also configured these two lines in my properties.xml file:
<property name="org.apache.manifoldcf.database.username" value="test"/>
<property name="org.apache.manifoldcf.database.password" value="test"/>
I'm using the Derby database since I cannot see how I could contact an
external PostgreSQL server on another host. PG is one of several database
systems the university supports. I guess there should be an option for
configuring external hosts and optionally turn on SSL encryption. Maybe
another ticket to create.
But first I want to run ManifoldCF on Tomcat using Derby, then deploy it
on
Resin and then try to configure an external PostgreSQL server.

Sure, if you want, create a ticket, and see if you can figure out what
the problems are. I'd start with not being able to reach the
stylesheet, actually. The "redirection" error sound like the crawler
UI is trying to present an error and resin is handling one of the java
standard tags in a non-standard way.

Resin is de facto application server at the university, but we also

I can try to deploy the war files on Tomcat instead. The error message
comes
from Resin, probably caused by a redirect after the http header is
written.
I can notify you, eventually create a patch, if I manage to run
ManifoldCF
on Resin.

I have never tried this on Resin, just on Tomcat and Jetty. Clearly
Resin as an application server is having difficulty doing some very
basic stuff.
FWIW, when we first started the Jetty development, I had to do nothing
whatsoever to the crawler UI or the war packaging to make it work. It
just worked. Your experiences with Resin are making me wonder if
Resin is indeed working up to Java standards.

I have placed the three war files into Resin's webapps directory and

I have also created my own home directory for ManifoldCF and copied
the
necessary files from the example directory. When I start Resin and
goes
to
... mcf-crawler-ui/, the start page shows up, but the page looks ugly
(I
guess the path to CSS files etc. are broken). And when I try to click
on
a
link, e.g. "List Output Connections", I get the following error:
java.lang.IllegalStateException: can't forward after writing HTTP

I find nothing in manifoldcf.log.
BTW: PostgreSQL is not configured. I will start using Derby until it
runs
stable on Resin.
