This is my lzx file and the java class - with the HashMap example I
actually get 2 rows in the datagrid, however no data shows up.
I initially had the return of String test() as the dataset

// sample trying to return an XML string
public String test() {
return "<quotes>"+
"<quote id=\"200\" text=\"quote 10\" firstname=\"Ruben\"
lastname=\"Reusser\" plan=\"1500\" type=\"Self\" date=\"1/1/2007\"/>"+
"<quote id=\"199\" text=\"quote 1\" firstname=\"Carla\"
lastname=\"Poulin\" plan=\"1500\" type=\"Family\" date=\"1/2/2007\"/>"+
"</quotes>";
}
public static Hashtable getProperties()
{
return System.getProperties();
}
// sample trying to return a HashMap
public HashMap test()
{
HashMap map = new HashMap();
map.put("id", "200");
map.put("text", "quote 10");
map.put("firstname", "Ruben");
map.put("lastname", "Reusser");
map.put("plan", "1500");
map.put("type", "Self");
map.put("date", "1/1/1907");
HashMap quoteMap = new HashMap();
quoteMap.put("quote1", map);
map.put("id", "201");
map.put("text", "quote 10");
map.put("firstname", "Ruben");
map.put("lastname", "Reusser");
map.put("plan", "1500");
map.put("type", "Self");
map.put("date", "1/1/1907");
quoteMap.put("quote2", map);
HashMap returnMap = new HashMap();
returnMap.put("quotes", quoteMap);
return returnMap;

Can you send a small example of what your code looks like ?
There is an example in the source distribution in
test/rpc/javarpc/serverenv.lzx, which accesses a server side call to
system environment info test.xmlrpc.SystemProp

hi
I am new thew openlaszlo and figured I do a little test program using
JavaRPC and the 4.0.2 release. I am trying to populate a dataset
(list)
from a value returned from my java class but seem to fail.
I can call the java class and get a return value (String) that is an
XML. However, I am not sure if that is the way I am supposed to do
it or
not. When I look at the dataset it's empty. Does anyone have an
example
program that does that?
I checked the mailing list and the forum but I am unable to find a
working example (I can find a couple of people asking the same
question).
Thanks
Ruben
