Thanks Christian. I discovered this in 7.5 because of a weird thing. I couldn't for the life of me get 6.8 to generate the right timezone -- i'm in EST and it kept saying GMT-500 which is at some level correct, but didn't allow me to query whether a given date was in daylight savings time. Through much pain and googling, I found that I need to update the tz data for jre 7, but when I finished I found, even through java classes that I ran separately reported the timezone correctly, when I went through basex, it still gave me the GMT tz not EST. So on a lark I tried it in 7.5 That's when 7.5 gave me the error, so I tried it again in 6.8 just to make sure the syntax was right. To my surprise 6.8 suddenly gave me the right tz. Something about running 7.5 seemed to reset the timezone data in 6.8. Any idea why that happened? Its one of the bang-your-head-against-a-wall type mysteries that seems to have no reason. Randy

Randy,

thanks for your update. I have further refined the Java mappings; please check out the latest stable snapshot [1].

Since 7.0, many details of our Java bindings have improved, but it’s generally difficult to find a solution that matches all cases. As there’s no lossless mapping available for Java and XQuery data types, we generally tend to recommend the usage of XQuery functions whenever possible. BaseX provides some few additional converter functions for dates that may be helpful to perform some of the tasks that are otherwise only possible via Java [2].

Best, Christian

Hi all,

I switched from 6.8 to 7.5 and I'm generating an error I didn't get in 6.8 when using Java Bindings There error is :[FORG0006] Invalid call of Java function: TimeZone.inDaylightTime(java(), java()) It appears that its problem is using the output of one java function in another function.

Is there some new way to do this in 7.5? Thanks Randy

The code is:

declare namespace tz = "java:java.util.TimeZone"; declare namespace dt = "java:java.util.Date"; declare namespace df = "java:java.text.DateFormat"; declare namespace cal = "java:java.util.Calendar"; declare namespace sdf = "java:java.text.SimpleDateFormat";

let $odate := xs:long(1345665817) let $edate := xs:long($odate)*1000 let $fdate := dt:new(xs:long($edate)) let $tmz := tz:getDefault() let $tbool := tz:inDaylightTime($tmz, $fdate)

return (

<results> <jdate>{$fdate}</jdate> <Timezone>{$tmz}</Timezone> <Daylight>{$tbool}</Daylight> </results> )
