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

<PARAM NAME="cookiehost" VALUE="<%=request.getServerName()%>">
<PARAM NAME="cookiepath" VALUE="<%=request.getContextPath()%>">

</applet>
