Servoy Application Server
Server doesn't
...
start
...
When
...
the
...
Servoy
...
Application
...
Server
...
will
...
not
...
start,
...
there
...
are
...
two
...
likely
...
reasons
...
for
...
it:
...
- Is
...
- the
...
- database
...
- containing
...
- the
...
- Servoy
...
- Repository
...
- running?
...
- Note
...
- that
...
- the
...
- Servoy
...
- Application
...
- Server
...
- doesn't
...
- start
...
- a
...
- database,
...
- not
...
- even
...
- the
...
- bundled
...
- PostgreSQL
...
- database.
...
- Does
...
- the
...
- application
...
- Server
...
- fail
...
- to
...
- start
...
- after
...
- disabling
...
- or
...
- updating
...
- the
...
- SSL
...
- settings?
...
- The
...
- passwords
...
- of
...
- the
...
- database
...
- connectiosn
...
- defined
...
- of
...
- the
...
- server
...
- and
...
- stored
...
- in
...
- the
...
- servoy.properties
...
- file
...
- are
...
- encrypted
...
- using
...
- the
...
- SSL
...
- settings.
...
- due
...
- to
...
- the
...
- update
...
- to
...
- the
...
- SSL
...
- settings,
...
- the
...
- passwords
...
- cannot
...
- be
...
- decrypted
...
- anymore.
...
- Remedy:
...
- manually
...
- reset
...
- the
...
- passwords
...
- in
...
- the
...
- servoy.properties
...
- file
...
If
...
the
...
above
...
mentioned
...
items
...
are
...
not
...
the
...
the
...
reason
...
for
...
the
...
Servoy
...
Application
...
Server
...
not
...
starting,
...
the
...
next
...
step
...
would
...
be
...
to
...
analyse
...
the
...
log
...
files:
...
- ../application_server/servoy_log.txt
...
- Â
...
Network errors
...
Some Java environments start with IPv6 Stack. If this happens, while actually running IPv4, the result might be network errors. In order to prevent errors, the Servoy Application Server can be started with a preference to use the IPv4 Stack.
- Open servoy_server.sh/servoy_server.bat
...
- in
...
- the
...
- <servoy>/application_server/
...
- directory
...
- using
...
- a
...
- text
...
- editor
...
- Add
...
- '-Djava.net.preferIPv4Stack=true'
...
- to
...
- the
...
- end
...
- of
...
- the
...
- line
...
- that
...
- starts
...
- with
...
- 'java'
...
- Save
...
- the
...
- change
...
- made
- Restart the Servoy Application Server
...
Server crashes
...
The Servoy Application Server is very robust and is known for its stability and extreme long uptime. In the unlikely event of a crash, this is most likely caused by an out of memory exception, caused byÂ
Servoy Smart Client
When experiencing problems with Smart Client starting or loosing connections, the following items might offer resolution. At any time, more information can be retrieved by enabling the Java WebStart console on the client machine prior to launching the Smart Client. This will open an additional console on the client machine with a client-side log. The Java WebStart console can be enabled in the Java Control Panel > Advanced > Java Console by checking the Show console option
...
Error: cannot find dataservice, it may not be running on server
...
This error is displayed in the Servoy Smart Client when it can't properly connect to the Servoy Application Server at startup. Most likely cause of this message is incorrect configuration of the Network Settings in combination with firewalls and proxies
...
Error: Connection to Servoy server is invalid
...
Invalid SSL Certificate or using a self-signed certificate, which is not supported for Smart Clients
...
Microsoft JScript compilation error: syntax error (Windows only)

pops

up

with

,
...
this
...
means
...
that
...
on

the

client
...
machine
...
Java
...
WebStart
...
is
...
configured
...
to
...
look

at
...
the

for

settings.
...
On

Windows
...
this
...
means

that

it

is

looking

Where

these

located

differs

per

Windows

version,

but

they

can

be

accessed

through

the

settings

...
The
...
solution
...
is
...
to
...
either
...
configure
...
Java
...
WebStart
...
to
...
use
...
"Direct
...
connection"
...
(Not
...
to
...
be
...
confused
...
with
...
Servoy's

Direct

mode)

or
...
to
...
uncheck
...
all
...
options
...
in
...
the

...
Settings
...
of
...
Windows.
...
As

both

options

are

system-wide

settings
...
they

can

influence

other

applications.
