Error during startup of alfresco 2.0 within Tomcat ...

[hr61369256]

Hi,

I have tried to get the release 2.0 running …

… but starting doesn't work in my environnement (Windows/MySQL/Java SDK 1.5/Tomcat). The former release 1.4 run very well. No problems during installation and startup …

Could someone tell me what I did wrong?

The Alfresco.log file is here:

You may have already solved this.  However, if not, here goes….

It appears you have another java process, probably an unstopped version of Alfresco, bound to the port.  Before starting Alfresco issue a command like:

-> ps -ef | fgrep java

If you see any java processes, explain them, e.g. you might have JBoss Portal running, or kill them.  If it appears the process is an unstopped Alfresco, i.e. you see Alfresco in the path, try

-> ./alf_stop.sh

in the Alfresco home directory first.

If still there after a few minutes, do

-> kill xxxxx

where xxxxx is the process ID of the java process.  If it still doesn't stop after a few minutes, do

-> kill -9 xxxxx

you can look in tomcat/logs/catalina.out to check on status.  Do a tail of the file.  If it says it is paused, then the kill -9 is probably appropriate.

Different people contributing to this thread have entirely different issues.
For example,  community member 'hr61369256' (this dicussion's originator)
was seeing:

java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
java.net.MalformedURLException: no protocol: Software ‍‍‍

As was pointed out, this is due to a bug in the JRE itself:  you MUST put
apps that use RMI on paths that don't include chars that require URL
escaping.   Thus, because user 'hr61369256' installed Alfresco on
a path with a space in it, RMI broke.  

Another user on this thread (community user 'ddupmul')
was seeing

Initialization of bean failed; nested exception is java.rmi.server.ExportException: internal error: ObjID already in use 
‍‍‍

There are two likely causes for a problem like this:

1. You already have a rmi registry on this port  (possibly another instance of alfresco, or some other program)


2. Your DNS setup is wrong

Note that DNS problems can be very subtle.
For example,  if you try to run on a machine that is served by DHCP
that hard-codes an IP address in an /etc/hosts file, and that hard-coded
IP address happens to not match the one given to you by DHCP,
then Spring's RmiServiceExporter will end up trying to bind to
an IP address that may not correspond to a network device.
If that happens, then the bind will get refused, a registry at the
*default* RMI will get created because Spring's RmiServiceExporter
makes a "best faith effort" by failing over to localhost but it won't
get any of the other settings that prevent conflicts downstream.
When those conflicts occur, you'll get "ObjID already in use".
Whew!


When in doubt,  check your network interface's ip address
using something like  ifconfig on unix, then ping your hostname
and see if the addresses match.   Also, remember to inspect
your process list for lingering Tomcat instances.   Another useful
tool on unix if some other process is causing trouble is 'lsof'.

I hope this helps.

Check your network configuration.

With Mac OS X, I updated my network configuration by adding a proxy configuration. It was enough to break my alfresco installation.

Yes, actually you should run the following command.

echo 127.0.0.1 `hostname` >> /etc/hosts

I had the same problem on a Debian Etch - your tip solved my problem. Thanks.

I got this problem with differences executing:
$ ping localhost
$ ping `hostname`

I fixed it adding a line y /etc/hosts:
echo 127.0.0.1      `hostname` >> /etc/hosts

I hope this helps
