  • Cannot find maven dependency, mysterious jar files

    - by natasha
    Hi, I am trying to build a simple war file which has a few jsps. However I am coming across an odd issue, for some reason during the packaging maven is pulling 4 jar files into the WEB-INF/lib. I have trimmed down all the fat from the pom file, and have grepped for any references to these jars without any success. I cannot figure out where maven is pulling them from. I tried 'mvn dependency:build-classpath' and the classpath is empty. Please help, these jars are corrupt and I cannot deploy this war file because of them. Thanks, natasha

Any idea what is the problem? Using windows server 2003. Attempting stop... Internet services successfully stopped Attempting start... Restart attempt failed. IIS Admin Service or a service dependent on IIS Admin is not active. It most likely failed to start, which may mean that it's disabled.

  • jquery .hide() bug in safari

    - by phil crowe
    ive been having issues with this hide bug thats only affecting safari. This is a simple vertical scroller that hides the first element in the list then shows the last. and works in everything apart from safari. the problem seems to be that the divs im working with here share the same class but have unique ids like #mycollectioncomment1, #mycollectioncomment2, #mycollectioncomment3 etc... however hiding just one of these divs hides all the other divs that share the same class. Ive tried .fadeOut(0) that everyone suggests as the work around but it just doesnt work here. var commentListCount = $(".myCollectionLatest").size(); var mycollclickCount = 0; var showingcomments = 5; if ($('.licomment').size() > 0) { showingcomments = 4; //alert("this"); } if ($('.lookInSeasonList').size() > 0) { showingcomments = 5; } if ($('.lookDescMiddle').size() > 0) { showingcomments = 8; } if ($('.MyCollectionsCollectionHolder').size() > 0) { showingcomments = 5; } // if (commentListCount > 5) { $(".myCollectionLatest").hide(); for (i = 0; i < showingcomments; i++) { $("#mycollectioncomment" + i).show(); } $('#mycolldown').click(function () { var element1, element2; if (showingcomments <= commentListCount) { mycollclickCount++; element1 = $("#mycollectioncomment" + mycollclickCount.toString()); element2 = $("#mycollectioncomment" + showingcomments.toString()); element1.closest('.licomment').hide(); element2.closest('.licomment').show(); showingcomments++; } }); $('#mycollup').click(function () { if (showingcomments <= 5) { } else { $("#mycollectioncomment" + mycollclickCount.toString()).show(); $("#mycollectioncomment" + mycollclickCount.toString()).closest('.licomment').show(); mycollclickCount--; showingcomments--; $("#mycollectioncomment" + showingcomments.toString()).hide(); $("#mycollectioncomment" + showingcomments.toString()).closest('.licomment').show();
