Welcome to Sweet Home 3D developers community. I hope you'll give us a chance to try your software (if you can open source it of course).
Sorry if the description of the parameters of SweetHome3DApplet class isn't clear enough. I tried to make logical choices according to the values you give to readHomeURL, writeHomeURL, listHomesURL and defaultHome parameters, and here are the most typical cases I can think about.
First their default values defined as follows:
readHomeURL="readHome.php?home=%s",
writeHomeURL="writeHome.php",
listHomesURL="listHomes.php",
defaultHome=""Then, the parameters defined as follows:
readHomeURL="%s",
writeHomeURL="",
listHomesURL="",
defaultHome="myHome.sh3d"If you want to let the end user save his changes, but still not let him create a new home from the applet, then you'll have to define writeHomeURL service, for example:
readHomeURL="readHome.php?home=%s",
writeHomeURL="writeHome.php",
listHomesURL="",
defaultHome="12345"If you want to let the end user open any home but never save his changes, the parameters could be as follows:
readHomeURL="%s",
writeHomeURL="",
listHomesURL="listHomes.php",
defaultHome=""On the other hand, looking at the SweetHome3D online source code, I've seen that you use listHomes.jsp, readHome.jsp, writeHome.jsp, readPreferences.jsp, and writePreferences.jsp as parameters for the SweetHome3DApplet, and I found a link to download php version of the first 3 files. Could you share the jsp version of these files?
I won't give you here the exact source code of the JSP pages I use, because it's valuable only in the context of sweethome3d.com where some data is stored in a database and an identification is required to open/save the homes of a user. So I prefer to give here translations of the existing php files that work on files local to the JSP pages and let you adapt them for your needs.<%-- listHomes.jsp
