I changed the Eclipse.ini to Xmx1024 (This is in the Eclipse resource
bundle on OS-X) and am still seeing the same issues: 1) data view in
BIRT shows columns, but no data, 2) if you bind the columns to a chart
and attempt to view the chart ("Preview" or "Run>View Report" then
Eclipse will immediately crash.On inspecting the data source in BIRT, it is clear that BIRT is receiving the SPARQL query code from Composer, but it is unable to execute the query to display the results. (see the error log below) Somehow the environment for the query in BIRT is inconsistent with Composer, my first guess was that the prefix information was not being passed to BIRT, so I explicitly added the prefixes to the query, but that did not seem to help either. Next guess was that BIRT was not using inference settings in composer and that is why it was not returning results. So I modified my query so that it did not need inference (by querying a specific class rather than an abstract superclass) and BIRT was able to see the data this time. So this is part of the problem. There is more: I created a graph with this (no inference) query. The data was visible when I bound the data to the graph. However when trying to view the graph, Eclipse crashed again, so there is something else going on with the handshake between BIRT and Composer in OS-X. Log after attempting to view query results in data source: A BIRT exception occurred.
