Обсуждение: doubt

Java takes a pretty conservative approach to security.  An applet
is only allowed to connect back to the server from which it was
loaded.  The database must be on the same computer as the web
app, or you must use tunnelling software.

Without more information I can't be sure that this is your issue,
but it seems likely.

If security is an issue, you can always sign your applet.

http://java.sun.com/j2se/1.4.2/docs/tooldocs/solaris/jarsigner.html
and
http://java.sun.com/j2se/1.4.2/docs/tooldocs/solaris/keytool.html
are your friends.

Also check that postgresql.jar is in your CLASSPATH as in :

<applet name="PhotoJApplet"

archive="../SMA_APPLETS.jar,../commons-httpclient-2.0.2.jar,../commons-codec-1.3.jar,../commons-logging.jar,../
crewapp,../postgresql.jar"
                code="com.gatewaynet.web.applets.PhotoJApplet.class"
                MAYSCRIPT
                width="800"
                height="300">
.......
<PARAM NAME="cookiename" VALUE="JSESSIONID">
<PARAM NAME="cookievalue" VALUE="<%=session.getId()%>">
<PARAM NAME="cookiehost" VALUE="<%=request.getServerName()%>">
<PARAM NAME="cookiepath" VALUE="<%=request.getContextPath()%>">
.......
</applet>
