The task of reading by program details
I played with human workflow api for some time of generation custom worklist application but I ran into a few problems.When I get a job you want with:
Task task = wfSvcClient.getTaskQueryService () .getTaskDetailsById (ctx, taskID);
I try to get a payload the Help task:
Support useful element = task.getPayloadAsElement ();
Everything seems fine for now, because the payload is, it seems, xml file that I'm looking for and it is built with this schema:
< scheme xmlns = "http://www.w3.org/2001/XMLSchema" targetNamespace = "http://xmlns.oracle.com/ns/vacationrequest."
xmlns:vacreq = "http://xmlns.oracle.com/ns/vacationrequest" elementFormDefault = "qualified" >
< feature name = 'Request' >
< complexType >
<>sequence
< element name = "pid" type = "string" / >
< element name = "creator" type = "string" / >
< element name = "fromDate" type = "date" / >
< element name = "date" type = "date" / >
< element name = "reason" type = "string" / >
< element name = "status" type = "string" / >
< / sequence >
< / complexType >
< / item >
< / schema >
But when I go to the child nodes of the application (node NodeList = payload.getChildNodes ()) it seems to me that there is a following xml construction:
< #text > < / #text >
< inp1:pid > < / inp1:pid >
< #text > < / #text >
< inp1:creator > < / inp1:creator >
< #text > < / #text >
< inp1:fromDate > < / inp1:fromDate >
< #text > < / #text >
< inp1:toDate > < / inp1:toDate >
< #text > < / #text >
< inp1:reason > < / inp1:reason >
< #text > < / #text >
< inp1:status > < / inp1:status >
< #text > < / #text >
without values inside nodes. When I look at the trail of Audit in Enterprise Manager this XML, it looks like this:
< application >
< inp1:pid > 222 - 22 - 2222 < / inp1:pid >
Marija Maric < inp1:creator > < / inp1:creator >
< inp1:fromDate > 2010-03-04 + 00:01 < / inp1:fromDate >
< inp1:toDate > 2010-03-06 + 00:01 < / inp1:toDate >
Holiday < inp1:reason > < / inp1:reason >
initial < inp1:status > < / inp1:status >
< / request >
Is it possible to extract the actual values programmatically? The biggest surprise for me here is the appearance of the #text tags.
I could use any help.
Thanks in advance

Hello
I used the dom parser to get the exact values of the payload.
Here is a code snippet.
Element rootelement = tx.getPayloadAsElement (); TX is the subject of the task
NodeList nl = rootelement.getElementsByTagName ("LeaveInputElement"); getting the element root
Node fstnode = nl.item (0);
Element fstElmnt = fstnode (element);
NodeList tstNmElmntLst = fstElmnt.getElementsByTagName ("Emp_name"); getting node Emp_name
Element tstNmElmnt = tstNmElmntLst.item (0) (element);
NodeList tstNm = tstNmElmnt.getChildNodes ();
System.out.println ("NAME of EMP =:" + ((node) tstNm.item (0)) .getNodeValue ()); getting the real value
I hope this helps...
Regs,
Vinciane

Environment variable folder is different when it is shown in the console and read by programs
Hi all
On our Windows Server 2008 machine, the TEMP and TMP environment variables all point to C:\Users\
\AppData\Local\Temp as seen in system properties. However, they appear like C:\Users\\AppData\Local\Temp\3 in Windows console command line. I also feel the same behavior in Windows Vista. This causes problems in our program. I don't know whence the '3' subdirectory and why these environment variable appear differently in the console.You have an idea about this problem? Thank you very much in advance!

How to start, stop and restart the task
Hi all
Need advice on what is the right way to start, stop, and restart a Java task?
I tried with Executors.newCachedThreadPool () or fixedThreadPool(), however I could not present the task once. My program crashed when I tried again the task again after a shutdownnow command()Tasks are designed to be run once. If you want to restart features, use a service:
http://docs.Oracle.com/JavaFX/2/API/JavaFX/concurrent/service.htmlService I posted in the following thread shows how to proceed:
MultithreadingUse of executors is unnecessary because a Service encapsulates the management of execution threads (although you can set your own liquidator on the service if you really need). Everything you need to do is use the start of the service, cancel, restart, and reset if necessary. If you do not use the cancel method, then you must ensure that your service is properly interrupt the current to cancel it for function, as you expect.
