[xwiki-devs] XWiki 3 .XAR decompression bug

Hi, Not sure I'm using the right channel but here is the deal. We were looking for a Tomcat-based Wiki and XWiki seemed to fit the bill (and in addition work with PostgreSQL that we also use). Unfortunately, this product, although I'm sure it's serious and works under certain strict contingencies, seems to have a very blocking bug under some other circumstances, so we will have to dig a bit more for something else, at least until your XWiki is more sturdy. But at least, having put a couple hours on it without results, we will report on our test: we installed version 3.1 (and then did the same test with version 3.0 with the same outcome). We installed the .war on Tomcat as documented in your web pages and configured it accordingly. In the end, that seemed to work in the sense that when we asked for the default page in a browser, we got an answer and also we saw that 41 tables were created in the database. As suggested, we then downloaded the official .xar file (we tried version 3.0 and then version 2.7 also) and uploaded it in the Import page. Then when we clicked on the link of the filename at the lower-left, the upper-right displayed: Archive xwiki-enterprise-wiki-3.0.xarDescription My packageVersion 1.0.0Author XWikiLicence LGPLselect none, all as expected, BUT THE GREY INNER FRAME THAT SHOULD DISPLAY A LIST OF CONTENT IN THE XAR IS... EMPTY, YES TOTALLY EMPTY. So clicking on the Import button will yield a message about selecting something but there's nothing to select. We tested the same in Firefox, IE and Chrome. There are no error message in HTML or JavaScript, nor anything special in any of the Tomcat logs or PostgreSQL log. The .xar files are valid in the sense that they can be fully decompressed by WinZip/WinRAR. Our hypothesis is that some XWiki code (probably the compression library) silently traps an exception and is so far incompatible with either Tomcat version 7 or Java version 6 or Windows 7 or Intel 64-bit. Sorry for you and good luck. A. R.
