Tomcat and Salesforce Issue
Hi all,
I have a web service setup on tomcat 5.5 that connects to Salesforce.com
through a web service call. This works fine and dandy but after it has been
left overnight it fails to connect when invoked. I had a similar problem
with another web service call that I was using so I dont think its a problem
with Salesforce. Also, if I restart the tomcat server, the web service
successfully connects to Salesforce until the next day. The web services are
running on apache axis2 which is deployed via a .war file.
Thanks for any support
James

sounds like salesforce people dropped the ball here
if the call to Salesforce WebService works only part of the time and not other times there has to be some delta(more than likely bringing a server offline or a SF misconfig) that Salesforce introduces at that point in time to not make SF system available
In the meanwhile I would rummage thru salesforce logs
Viel Gluck

SF is an online service run by a company. I don't believe they are going
to provide their log files to a customer.
SF should be available all the time. If not, their API documentation
should state regular downtimes (such as between 0100-0200 GMT).
I suspect the problem is with the client, not SalesForce.

op mentioned the SF webservice becomes unavailable at 'weird' times
(more than likely the SF webserver is going offline for backup)
if you can post the SF log we'll take a look and try to figure out the error

Hmm... if your database connection died, could that cause the behavior
you're experiencing? If so, and it happens overnight, perhaps you have a
firewall killing your db connection.
Are you using a connection pool? If so, try configuring a connection
validation query appropriate for your database (and connection pool).
Certainly getting more information will be helpful. Note that it's not
good to "swallow" exceptions by catching them and either ignoring them
or throwing an unrelated exception without either logging the exception
or wrapping it up in another one. Avoiding swallowing your exceptions
would have helped you out, here.

Sorry about that, I have checked the catalina.out file and it says that an
exception is thrown, I will have a ensure it prints the stack trace and will
have a look at it in the morning - sorry I can't test this earlier but I
need to wait for it to fail overnight. At the moment I simply catch the
exception that is thrown and it simply gives a null error. This I would
normally expect to occur when there is no data present in the database,
however, I have also printed the SQL query and checked it against the
database and it brings back results. I'll get that stack trace to you asap.
