Thank you. That solves the db shutdown issue. Any idea why connecting to port 9001 via telnet doesn't work? That method is used a lot.

You do need to run ant dbgui in a different window to ant db - which you should run first.

Thanks for your reply Tom I do appreciate it, but sources.xml,, pathnames in don't mean
anything to me. I am not familiar with java nor tomcat. I am on a steep
learning curve here and am just trying to get the Quickstart running to
become familiar with this whole thing. I'm used to apache and cgi's and
fastcgi's and not this tomcat and java stuff.

I also tried the ant dbgui that was suggested but I don't think that's
working either, I get this:

[java] java.sql.SQLException: socket creation error
[java] at org.hsqldb.jdbc.jdbcUtil.sqlException(Unknown Source)
[java] at org.hsqldb.jdbc.jdbcConnection.<init>(Unknown Source)
[java] at org.hsqldb.jdbcDriver.getConnection(Unknown Source)
[java] at org.hsqldb.jdbcDriver.connect(Unknown Source)
[java] at
[java] at
[java] at
org.hsqldb.util.ConnectionDialog.createConnection(Unknown Source)
[java] at org.hsqldb.util.DatabaseManager.main(Unknown Source)

I do get the HSQL Database Manager window up but that "socket creation
error" message is suspect.

Is ant dbgui supposed to start the db too or do I still have to do an ant
db in another window?

I dropped your war file into my tomcat 5.5 webapps folder, restarted
tomcat, substituted sources.xml and for
my own (which point to my prototype sources and groups registry, not
the quickstart ones) and changed the pathnames in to
point to someplace that exists in my file system. Restarted tomcat
again, and it works fine.

Not sure what to conclude, but perhaps that helps you to focus your
search for the trouble.

At first I thought I was on to something when you asked for the war
file and I didn't have one, so I made one, but it acts the same. I
did the dist and copied everything from the dist/grouper directory to
webapps/grouper. Now that I have a war file I see when I start tomcat
it creates and populates the webapps/grouper directory itself.

I seem to have made some head way though. I am not running apache
anymore during this endeavor.

I think I'm starting to understand some things, I got this:

HTTP Status 404 - /grouper/index.jsp


*type* Status report

*message* _/grouper/index.jsp_

*description* _The requested resource (/grouper/index.jsp) is not


Apache Tomcat/5.5.20

When neither the grouper.war file nor the webapps/grouper copied from
the dist existed. So that the fact I didn't get that when I did the
dist says it was sort of working. So now by the fact I'm getting a
blank screen says it's trying to work.

I've included my .war file which I am now using. (gzip'ing it didn't
help much so I didn't.)

No, nothing.

I'm trying to get QuickStart working and this is frustrating. I
the instructions provided but I can't get it to work. I am no
java or
tomcat expert so that probably has a lot to do with it.

What versions of Java, Ant and Tomcat are you using?

It seems to be doing something I connect to
and it takes me to http://localhost:8080/grouper/
then I get a white screen and a Done. I look at the page source
and I
have this:

<?xml version="1.0" encoding="iso-8859-1"?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"


<html xmlns=""; lang="en-US"


Do you get any error in the Tomcat logs e.g. catlina.out?

In httpd.conf I put this:

# <IfModule \!mod_jk.c>
LoadModule jk_module modules/
# </IfModule>
# JkWorkersFile "/usr/local/tomcat/conf/jk/"
JkLogFile "/var/log/httpd/mod_jk.log"
JkLogLevel emerg
JkMount /grouper/* ajp13

I had to comment out the IfModule(s) otherwise it wouldn't load.
And if I
don't comment out 'JkWorkersFile
"/usr/local/tomcat/conf/jk/"' apache won't
start. I
don't know if I need that for QuickStart but the instructions don't
address it either way and if I need a where
does it
come from?

In a production environment it is quite likely you would place
Apache in front of Tomcat and use mod_jk, however, in order to get
the QuickStart to work you don't need to do anything with Apache
or mod_jk - you can connect to Tomcat directly.

I'm also still getting this when I try to stop HSQLDB:

[java] Exception in thread "HSQLDB Connection @1b543c88"
java.lang.OutOfMemoryError: Java heap space

This is a direct consequence of using Telnet to shutdown the
database. I've never tried doing it this way before.

The QuickStart build file also has a 'dbgui' target which will
load a simple database manager ui which lets you query the
database, and also shut it down. If you can't do this directly on
the machine where the database is installed i.e. no X windows
capability, you can connect from a 'desktop' machine by changing
the localhost in the URL below:

<java dir="." classname="org.hsqldb.util.DatabaseManager"
classpathref="db.class.path" fork="true">
<arg line="-url jdbc:hsqldb:hsql://localhost:9001"/>

This is all extremely frustrating when you follow the
instructions and it
doesn't work. Granted being unfamiliar with java and tomcat
doesn't help
and I think I have the jk connector installed properly, but the
instructions should take this into account that people not
familiar with
all these components will be asked to install this.

I hear your frustration, and the QuickStart is supposed to make it
easy to get started specifically to avoid such frustration - and
it generally seems to achieve this.

If there is no error in the Tomcat log, I will try and come up
with a 'patch' which will produce some diagnostic output. It looks
like the error is occurring during initialisation before any
Grouper / Subject API calls are made.

In addition you could send me your WAR file + the contents of
grouper-qs/grouper/conf and I'll take a look at them to see if I
can spot anything.
