I fixed my problem finally. Simply, I thought I had jasper server 1.2 but it was 1.1 Now that I have updated, I do see my catalog and my cube but when I go in the query designer (with the XMLA connection and query language set to "XMLA-MDX") I have the following message : "defaultCloseOperation must be one of : DO_NOTHING_ON_CLOSE, HIDE_ON_CLOSE, or DISPOSE_ON_CLOSE". Funny enough! Anyone else has this message? This bug should be easy to fix. Thx
