Jan,
Try
appcon.put("org.eclipse.datatools.enablement.oda.xml.inputStream ", bais);
where bais is a bytearrayinputstream.
I did this in report script like:
//beforeOpen of datasource
importPackage( Packages.java.io );
var mystr = "<?xml version=\"1.0\"?>";
mystr = mystr + "<library>";
mystr = mystr + "<book category=\"COOKINGgg\">";
mystr = mystr + "<title lang=\"en\">The test2 Cook Book</title>";
mystr = mystr + "<author name=\"Miguel Ortiz\" country=\"es\"/>";
mystr = mystr + "<sold>10,312</sold>";
mystr = mystr + "<year>2005</year>";
mystr = mystr + "</book>";
mystr = mystr + "<book category=\"CHILDREN\">";
mystr = mystr + "<title lang=\"en\">Everyone is Super Special</title>";
mystr = mystr + "<author name=\"Sally Bush\" country=\"uk\"/>";
mystr = mystr + "<sold>8,222</sold>";
mystr = mystr + "<year>2005</year>";
mystr = mystr + "</book>";
mystr = mystr + "<book category=\"AUTOBIOGRAPHY\">";
mystr = mystr + "<title lang=\"en\">Japanese Greetings</title>";
mystr = mystr + "<author name=\"Taro Yamada\" country=\"uk\"/>";
mystr = mystr + "<sold>7,852</sold>";
mystr = mystr + "<year>2005</year>";
mystr = mystr + "</book>";
mystr = mystr + "<book category=\"WEB\">";
mystr = mystr + "<title lang=\"en\">Query Kick End</title>";
mystr = mystr + "<author name=\"James McGovern\" country=\"us\"/>";
mystr = mystr + "<sold>15,111</sold>";
mystr = mystr + "<year>2006</year>";
mystr = mystr + "</book>";
mystr = mystr + "<audio format=\"CD\" category=\"MUSIC\">";
mystr = mystr + "<title lang=\"en\">Feels Like Home</title>";
mystr = mystr + "<artist name=\"Norah Jones\" country=\"us\"/>";
mystr = mystr + "<sold>9,675</sold>";
mystr = mystr + "<year>2005</year>";
mystr = mystr + "</audio>";
mystr = mystr +"</library>";
JavaStr = new java.lang.String( mystr );
bais = new ByteArrayInputStream( JavaStr.getBytes());
appcon = reportContext.getAppContext();
//apcontext setting
appcon.put("org.eclipse.datatools.enablement.oda.xml.inputStream ", bais);

Cyril,
What path do you have in the datasource for the xml file?

Cyril,
When you say it works on windows are you swapping in the byte array?
Where does the data come from. You should be able to just change the
filelist in the beforeOpen script to retrieve the file from somewhere
else. Can you post the report?

Thanks for posting. If you want you could open a bugzilla entry to get
this improved.
