How to get ServletContext from HttpServletRequest when there is no session?
Does anyone know of a way to be able to pull the ServletContext from an HttpServletRequest if there is not a session available?
You could always just do:
request.getSession(true).getServletContext()The true argument to getSession() creates a session if there isn't one. Alternatively, you can store the ServletConfig object you receive in the Servlet's init() method, and get the ServletContext through that.

HT4859 how to get pictures from icloud when Iphone is stolen
how to pictures and music from Icloud when phone is stolen
Photo stream photos can only be access from another iOS device or computer signed into your iCloud account with photo stream enabled. Camera roll photos (and videos) are contained in the iPhone backup, assuming you have one. If you backed up to your computer using iTunes, you can extract the photos from the backup using 3rd party software such as iPhone Backup Extractor. If you backed up to iCloud, your these photos can only be accessed by restoring the backup to another iOS device.
Music isn't included in the backup; it should be in your iTunes library. Music purchased from iTunes can be redownloaded again for free (http://support.apple.com/kb/HT2519), but music from other sources, if not in your iTunes library, cannot be recovered. -
How to get sound from phone when bluetooth connected
Easily paired my Plantronic bluetooth headset - piece of cake. However, if I'm not on the phone, I don't keep it on my ear. Sounds, except phone ringing, only come thru the headset whe it is on. I would like to hear the other sounds (i.e. notifications, text message alerts, other alerts) from the phone when my bluetooth headset is connected. It would be a pain to have to turn the headset on/off just to hear anything from the phone. I actually missed a meeting as the phone made no noise for my calendar reminder.
I would like the option of routing the tones/alert sounds to either phone or headset or just have it automatically do both.
Thanks
lawashbuIm afraid that disconnecting your blue tooth devise would be the only answer to your problem im afraid that is the only way
Hope this helped

Hello. When I turned on my Ipone 4s today all of my contacts were gone. They are backed up in iCloud but can't figure out how to get them from there back to my phone. Aren't them supposed to sync automatically over wifi? Can someone please help me?
Hello jllew333
Check to make sure that Contacts is toggled on to sync by going to Settings > iCloud. Also go to iCloud.com to see if the contacts are showing up there to see if it syncing those contacts.

I see how to delete songs from iPad, but there are some songs that don't give me the option to delete when I swipe them. Why can't I get rid of these songs?
Do they have a cloud icon next to them? If they do, they aren't on the iPad so you can't delete them. They are in iCloud ready for you to download them if you want to and they are visible in the music app for this purpose.
If you don't want to see these songs that are in iCloud, go to Settings> iTunes & App Store>Show all>Music>Off. -

How do I keep emails from being deleted on my iPhone 6? Emails get deleted from phone when I startup desktop computer and they are downloaded from sever. Is POP3 no longer supported on IOS 8.1?
Have you seen this?
Using a POP account with more than one device - Apple Support
A better solution is if your email provider uses IMAP. IMAP sync email folders between multiple devices. Meaning any device will receive the email, all sent email can be seen on the devices. If you delete email from one device the email is deleted from all the other devices. Check with your email provider to see if they offer IMAP services.
If they do not your choices are to 1) configure email on the PC to keep Mail on the mail server or 2) change email providers to something like Gmail or Outlook.com (as examples). FWIW I use Cox IMAP email and fully sync email between a Win 8.1 Update 1 laptop, a Win 7 desktop, an iPad 4, an iPhone 4 and an iPhone 5S. -
How to get UTF-8 encoding when create XML using DBMS_XMLGEN and UTL_FILE ?
How to get UTF-8 encoding when create XML using DBMS_XMLGEN and UTL_FILE ?
Hi,
I do generate XML-Files by using DBMS_XMLGEN with output by UTL_FILE
but it seems, the xml-Datafile I get on end is not really UTF-8 encoding
( f.ex. cannot verifying it correct in xmlspy )
my dbms is
NLS_CHARACTERSET = WE8MSWIN1252
NLS_NCHAR_CHARACTERSET = AL16UTF16
NLS_RDBMS_VERSION = 10.2.0.1.0
I do generate it in this matter :
declare
xmldoc CLOB;
ctx number ;
utl_file.file_type;
begin
-- generate fom xml-view :
ctx := DBMS_XMLGEN.newContext('select xml from xml_View');
DBMS_XMLGEN.setRowSetTag(ctx, null);
DBMS_XMLGEN.setRowTag(ctx, null );
DBMS_XMLGEN.SETCONVERTSPECIALCHARS(ctx,TRUE);
-- create xml-file:
xmldoc := DBMS_XMLGEN.getXML(ctx);
-- put data to host-file:
vblob_len := DBMS_LOB.getlength(xmldoc);
DBMS_LOB.READ (xmldoc, vblob_len, 1, vBuffer);
bHandle := utl_file.fopen(vPATH,vFileName,'W',32767);
UTL_FILE.put_line(bHandle, vbuffer, FALSE);
UTL_FILE.fclose(bHandle);
end ;
maybe while work UTL_FILE there is a change the encoding ?
How can this solved ?
Thank you
Norbert

I tryed to work with dbms_xslprocessor.clob2file,
that works good,
but what is in this matter with encoding UTF-8 ?
in my understandig, the xmltyp created should be UTF8 (16),
but when open the xml-file in xmlSpy as UTF-8,
it is not well ( german caracter like Ä, Ö .. ):
my dbms is
NLS_CHARACTERSET = WE8MSWIN1252
NLS_NCHAR_CHARACTERSET = AL16UTF16
NLS_RDBMS_VERSION = 10.2.0.1.0
-- test:
create table nh_test ( s0 number, s1 varchar2(20) ) ;
insert into nh_test (select 1,'hallo' from dual );
insert into nh_test (select 2,'straße' from dual );
insert into nh_test (select 3,'mäckie' from dual );
insert into nh_test (select 4,'euro_€' from dual );
commit;
select * from nh_test ;
S0 S1
1 hallo
1 hallo
2 straße
3 mäckie

open rc FOR SELECT * FROM ( SELECT s0,s1 from nh_test );
dbms_xslprocessor.clob2file( xmltype( rc ).getclobval( ) , 'XML_EXPORT_DIR','my_xml_file.xml');
end;
( its the same when using output with DBMS_XMLDOM.WRITETOFILE )
open in xmlSpy is:
<?xml version="1.0"?>

How to get acknowlgmnt from EFT (debt card swap) machine from swing app.
Hi,
Please some 1 let me know how to get acknowlegdement from EFT ( debit card Swap) machine once it is connected to the computer.
I have a code which seems to have no errors ut it I am not sure whether the EFT machine will be able to send or recieve the data once the car is swaped. because i dont know what is the response of the EFT machine when connected to the computer though a java swing class.
I know it will be quite tidious job for you to go through my program but this is all i can do...or atleast give me a link where i can refer to such case.......I am using eclipe Ide....and have searched alot on google too......Vish_1x1 wrote:

Do you mean a card reader? An EMV terminal? A PDQ? What? Where did it come from? Start there. If you need to get this thing working, you must be part of an enterprise, which has access to resources such as hardware vendor support, merchant banking services and EFT software vendors. If you're not, then you might as well abandon all hope of using this machine to take cards on your own, because you can't. End of story

How to get BOOLEAN from STORED FUNCTION
We are calling legacy PLSQL stored procedures and functions via named queries. This has worked fine so far, but there are some functions which return the type 'BOOLEAN'. e.g.
FUNCTION some_function( some_argument IN NUMBER) RETURN BOOLEAN;
Where the return type is BOOLEAN calling the named query fails with
Local Exception Stack:
Exception [TOPLINK-4002] (Oracle TopLink - 10g Release 3 (10.1.3.0.0) (Build 060118)): oracle.toplink.exceptions.DatabaseException

How to get BOOLEAN from STORED PROCEDURES
Re: Creating Named Query: from OracleCallableStatement
This would possibly be due to 'restriction in the OCI layer'. Can anyone help? Is there really now way to call a valid PLSQL stored function via a named query when the return type is BOOLEAN?
thanksI can't comment on possible issues you might have with the driver, but if it can be done in JDBC, it should be possible in TopLink.
TopLink has the StoredFunctionCall which extends the StoredProcedureCall but adds an unnamed ouput parameter in the first spot of its parameter list. You will need to get the databasefield and set its type to BOOLEAN ie:
DatabaseField returnField = (DatabaseField)yourStoredFunctionCall.getParameters().firstElement();
returnField.setName(name);
returnField.setSqlType(Type.BOOLEAN);Be sure not to use the setType() method, as I believe TopLink will try to use the Type.BIT when a boolean class is used as the classtype.

Issue using extractval to get the node value when there is namespace
I created the db with a XMLType column:
CREATE TABLE mytable1 (key_column VARCHAR2(10) PRIMARY KEY, xml_column1 XMLType);
Then inserted one row:
INSERT INTO mytable1 (key_column,xml_column1) VALUES ('test', XMLType('<MY_TEST xmlns="http://xmlns.oracle.com/ku" version="1.0">
<SCHEMA>SYSTEM</SCHEMA>
<NAME>TABLE41</NAME>
<TEST_GROUP>TEST_GRP_RMP</TEST_GROUP>
<TEST_NAME>DEPARTTEST</TEST_NAME>
<FUNCTION_SCHEMA>SYSTEM</FUNCTION_SCHEMA>
<TEST_FUNCTION>EXCLUDE_TABLE</TEST_FUNCTION>
<STATEMENT_TYPE_LIST>
<STATEMENT_TYPE_LIST_ENTRY>
<NAME>SELECT</NAME>
</STATEMENT_TYPE_LIST_ENTRY>
</STATEMENT_TYPE_LIST>
<UPDATE_CHECK>Y</UPDATE_CHECK>
<ENABLE>Y</ENABLE>
<STATIC_POLICY>N</STATIC_POLICY>
<TEST_TYPE>DBMS_RLS.DYNAMIC</TEST_TYPE>
<LONG_PREDICATE>N</LONG_PREDICATE>
</MY_TEST>'));
Then I ran:
select extractValue(xml_column1,'MY_TEST/TEST_NAME') policy from mytable1;
There is nothing returned.
If i do not have "xmlns="http://xmlns.oracle.com/ku" " in MY_TEST node, then the correct value returned.
Please advise how could I get the node value when there is namespace? Thanks.This is a known issue. In the third parameter of extractvalue, set the namesapce. Then it works.
