How to disable browser caching for a specific JSP

Is it possible to keep the browser from caching a JSP? If so how?

you can put
response.setHeader("pragma","no-cache");
response.setHeader("cache-content","no-cache");
response.setHeader("expires",0);
in your jsp that will do..

How to disable memory cache for SL410?

Hi,
My lenovo thinkpad SL410 has Windows 7 prof edition as its OS. But in the last few months it frequently crashes. Many times when I use Chrome browser status would indicate AppCache, and that's an evil OMEN for its usually the prelude of crash. Other browser may or may not have such issue, however, Chrome is really my preferred web browser.
Some research seems to suggest disabling memory cache via BIO setup would resolve it. And here's my lenovo's BIO info:
Version: 1.23
Date: 2009-10-19
but it does not have any info as to who's its maker or the like. And I don't see any option in the BIO setup that would allow me to disable cache. So, two questions,
a) Is it possible to disable memory cache for SL410?
b) if so how?
Thanks.

Hi mujno,
As I know currently there is no programmatically way to clean cache for WebView, see Matt's blog:How to clear the WebView cache
However if you are developing an enterprise app, you should be able to invoke some scripts to clean for you, see this for more information:Brokered

How to disable webview cache for Windows Phone 8.1 Runtime universal app?

Is it possible to disable cache for the Webview control for a Windows Phone 8.1 runtime universal app? My App seems to be remembering the information it received the first time. My app logs me into a service and when I go back to rerun app in the emulator
(without completing shutting down the emulator) it logs me in automatically rather than giving me the prompt. This behavior is in the NavigationCompleted handler if that helps explain a bit more on where I am hitting this issue.
If I were to shut off the emulator completely and then restart it then I am prompted for the login name and password again. I have gotten over this cache issue, when I was using the HttpClient in other part of my app, by sending the no-cache in the header
as:
client.DefaultRequestHeaders.Add("Cache-Control", "no-cache");
Can I do something similar for the webview control?
thanks

How to disable safari autofill for a specific website

Hi!
I'm using Safari 6.1 and would like to disable autofill for a specific website. I'm learning french on duolingo, and it involves typing phrases, and similar ones tend to come up. Now safari saves every phrase I write, and tries to autocomplete other ones, which is quite annoying since i can't write a shorter sentence without it being autocompleted to something wrong. I've figured out how to remove the site from autofill, but it keeps coming back every time I write something new, and I don't want to keep removing it. Can I permanently disable autofill (or autocomplete, or whatever it's called) for that specific website?
Thank you!

From your Safari menu bar click Safari > Preferences then the Privacy tab.
Click: Remove All Website Data
Quit and relaunch Safari then try that website.

How to disable BOP rescheduling for one specific location?

Hi Experts,
We are now processing BOP with rescheduling for request with conditions for all locations. But we would like to separate one location. How can we disable the BOP rescheduling for that specific location? Is there a customizing setting to maintain that location list?
Thanks a lot
best regards,

Dear Wenyan,
in standard you can only exclude locations from BOP while filtering, in the filter variant.

How to create an EventListener for a specific keyboard press?

Hello,
I have been trying to figure out how to switch my actionscript3 from a mouse click to a keyboard press. I'm new to Flash, but the problem I keep coming to is that I need to have 3 separate keys programmed in to do three seperate outcomes. I have messed around with eventListeners for keyboard presses, but I cannot figure out how to have flash listen for a specific key press and then do an action based on that specific key press.
Here is my actionscript. Any suggestions on how I can modify the mouse clicks to be keyboard presses, where key 's' = btn1 and triggers gotoAndPlay(2), 'g' = btn2 and triggers gotoAndPlay(3), 'k' = btn3 and triggers gotoAndPlay(4) as outline below. I also need my timer and writing to an exteral file to remain the same.
stop();
var startTime:Number=getTimer();
var elapsedTime:Number;
stream.writeUTFBytes("Item1,");
function BTN1Action(eventObject:MouseEvent) {
     elapsedTime = getTimer() - startTime;
          stream.writeUTFBytes("Tar1,");
          stream.writeUTFBytes(elapsedTime.toString());
          stream.writeUTFBytes("\n");
          gotoAndPlay(2);
function BTN2Action(eventObject:MouseEvent) {
          elapsedTime = getTimer() - startTime;
          stream.writeUTFBytes("Tar2,");
          stream.writeUTFBytes(elapsedTime.toString());
          stream.writeUTFBytes("\n");
          gotoAndPlay(3);
function BTN3Action(eventObject:MouseEvent) {
          elapsedTime = getTimer() - startTime;
          stream.writeUTFBytes("Tar3,");
          stream.writeUTFBytes(elapsedTime.toString());
          stream.writeUTFBytes("\n");
          gotoAndPlay(4);
BTN1.addEventListener(MouseEvent.CLICK, BTN1Action);
BTN2.addEventListener(MouseEvent.CLICK, BTN2Action);
BTN3.addEventListener(MouseEvent.CLICK, BTN3Action);
Any assistance with this is greatly appriciated.

Assuming you want to monitor key press on the button BTN1, you can do following:
// Add a key up event listener on the button (or on the source where the key press needs to be captured)
BTN1.addEventListener(KeyPress.KEYUP, BTN1KeyUpAction);
// BTN1KeyUpAction sample, you can modify this
function BTN1KeyUpAction(e:KeyboardEvent):void {
    if(e.keyCode == Keyboard.S) {
    gotoAndPlay(2);

How to disable network connections for an application

Hi to all,
I would like to know if there is any way a user can disable network connections for a specific application.
Thank you,
Xwang

Yes, but I would like to block only a specific application, not all the traffic from the PC.
I've found this "solution" which uses iptables on the net:
"Add a group to your system (I use nonet myself), then add a rule to your output chain like this: -A OUTPUT -m owner --gid-owner nonet -j REJECT --reject-with icmp-net-unreachable Run the program for which you know in advance that you want to block, with sg (sg nonet "your_prog your_args")."
Do you think is it right?
Another suggestion was to use unshare to call the program disabling the net for that program only.
The problem is that unshare is runnable only by root so, in case, I should turn on its setuid flag in order to execute the program as a normal user, but I don't know if it is safe to do that.

Disable forward scheduling for a specific material

Hi experts.
We have a requirement to disable forward scheduling for a specific material during ATP check in sales order and delivery processing. I played with some configurations in "Basic functions > Availability check and transfer of requirements" and "Basic functions > Delivery scheduling and transportation scheduling", but none could help.
Notice: we use APO.
Example:
Material X - has 108 pieces in stock and a production order of 1000 pieces scheduled on Feb 11.
If I place a sales order of 109 pieces with requested delivery date of Feb 8, I need the system to not confirm this quantity, instead of confirming the quantity on Feb 13, as of standard behavior.
Regards,
Fábio Scaravelli

Unfortunately, I do not know much about APO. However, I had a quick look and saw the the function responsible for scheduling in APO is /SAPAPO/APO_SCHEDULING. Within this FM, there are two user exits called:
EXIT_/SAPAPO/SAPLVCRM_001
EXIT_/SAPAPO/SAPLVCRM_002
I am unsure if these can be utilised to achieve the desired behaviour. However, they may be worth investigating.

How to disable an alert for specific time period in SCOM 2012 R2

Hello,
Is there any option to disable an alert for specific time period in SCOM 2012 R2
Regards,
angs

No. But you can use the scheduler module in your rule or monitor, which will dictate when the workflow will actively run on the agent - hence disabling alerting for that time period.

How to create a cache for JPA Entities using an EJB

Hello everybody! I have recently got started with JPA 2.0 (I use eclipseLink) and EJB 3.1 and have a problem to figure out how to best implement a cache for my JPA Entities using an EJB.
In the following I try to describe my problem.. I know it is a bit verbose, but hope somebody will help me.. (I highlighted in bold the core of my problem, in case you want to first decide if you can/want help and in the case spend another couple of minutes to understand the domain)
I have the following JPA Entities:
@Entity Genre{
private String name;
@OneToMany(mappedBy = "genre", cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Collection<Novel> novels;
@Entity
class Novel{
@ManyToOne(cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Genre genre;
private String titleUnique;
@OneToMany(mappedBy="novel", cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Collection<NovelEdition> editions;
@Entity
class NovelEdition{
private String publisherNameUnique;
private String year;
@ManyToOne(optional=false, cascade={CascadeType.PERSIST, CascadeType.MERGE})
private Novel novel;
@ManyToOne(optional=false, cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Catalog appearsInCatalog;
@Entity
class Catalog{
private String name;
@OneToMany(mappedBy = "appearsInCatalog", cascade = {CascadeType.MERGE, CascadeType.PERSIST})
private Collection<NovelEdition> novelsInCatalog;
The idea is to have several Novels, belonging each to a specific Genre, for which can exist more than an edition (different publisher, year, etc). For semplicity a NovelEdition can belong to just one Catalog, being such a Catalog represented by such a text file:
FILE 1:
Catalog: Name Of Catalog 1
"Title of Novel 1", "Genre1 name","Publisher1 Name", 2009
"Title of Novel 2", "Genre1 name","Pulisher2 Name", 2010
FILE 2:
Catalog: Name Of Catalog 2
"Title of Novel 1", "Genre1 name","Publisher2 Name", 2011
"Title of Novel 2", "Genre1 name","Pulisher1 Name", 2011
Each entity has associated a Stateless EJB that acts as a DAO, using a Transaction Scoped EntityManager. For example:
@Stateless
public class NovelDAO extends AbstractDAO<Novel> {
@PersistenceContext(unitName = "XXX")
private EntityManager em;
protected EntityManager getEntityManager() {
return em;
public NovelDAO() {
super(Novel.class);
//NovelDAO Specific methods
I am interested at when the catalog files are parsed and the corresponding entities are built (I usually read a whole batch of Catalogs at a time).
Being the parsing a String-driven procedure, I don't want to repeat actions like novelDAO.getByName("Title of Novel 1") so I would like to use a centralized cache for mappings of type String-Identifier->Entity object.
Currently I use +3 Objects+:
1) The file parser, which does something like:
final CatalogBuilder catalogBuilder = //JNDI Lookup
//for each file:
String catalogName = parseCatalogName(file);
catalogBuilder.setCatalogName(catalogName);
//For each novel edition
String title= parseNovelTitle();
String genre= parseGenre();
catalogBuilder.addNovelEdition(title, genre, publisher, year);
//End foreach
catalogBuilder.build();
2) The CatalogBuilder is a Stateful EJB which uses the Cache and gets re-initialized every time a new Catalog file is parsed and gets "removed" after a catalog is persisted.
@Stateful
public class CatalogBuilder {
@PersistenceContext(unitName = "XXX", type = PersistenceContextType.EXTENDED)
private EntityManager em;
@EJB
private Cache cache;
private Catalog catalog;
@PostConstruct
public void initialize() {
catalog = new Catalog();
catalog.setNovelsInCatalog(new ArrayList<NovelEdition>());
public void addNovelEdition(String title, String genreStr, String publisher, String year){
Genre genre = cache.findGenreCreateIfAbsent(genreStr);//##
Novel novel = cache.findNovelCreateIfAbsent(title, genre);//##
NovelEdition novEd = new NovelEdition();
novEd.setNovel(novel);
//novEd.set publisher year catalog
catalog.getNovelsInCatalog().add();
public void setCatalogName(String name) {
catalog.setName(name);
@Remove
public void build(){
em.merge(catalog);
3) Finally, the problematic bean: Cache. For CatalogBuilder I used an EXTENDED persistence context (which I need as the Parser executes several succesive transactions) together with a Stateful EJB; but in this case I am not really sure what I need. In fact, the cache:
Should stay in memory until the parser is finished with its job, but not longer (should not be a singleton) as the parsing is just a very particular activity which happens rarely.
Should keep all of the entities in context, and should return managed entities form mehtods marked with ##, otherwise the attempt to persist the catalog should fail (duplicated INSERTs)..
Should use the same persistence context as the CatalogBuilder.
What I have now is :
@Stateful
public class Cache {
@PersistenceContext(unitName = "XXX", type = PersistenceContextType.EXTENDED)
private EntityManager em;
@EJB
private sessionbean.GenreDAO genreDAO;
//DAOs for other cached entities
Map<String, Genre> genreName2Object=new TreeMap<String, Genre>();
@PostConstruct
public void initialize(){
for (Genre g: genreDAO.findAll()) {
genreName2Object.put(g.getName(), em.merge(g));
public Genre findGenreCreateIfAbsent(String genreName){
if (genreName2Object.containsKey(genreName){
return genreName2Object.get(genreName);
Genre g = new Genre();
g.setName();
g.setNovels(new ArrayList<Novel>());
genreDAO.persist(t);
genreName2Object.put(t.getIdentifier(), em.merge(t));
return t;
But honestly I couldn't find a solution which satisfies these 3 points at the same time. For example, using another stateful bean with an extended persistence context (PC) would work for the 1st parsed file, but I have no idea what should happen from the 2nd file on.. Indeed, for the 1st file the PC will be created and propagated from CatalogBuilder to Cache, which will then use the same PC. But after build() returns, the PC of CatalogBuilder should (I guess) be removed and re-created during the succesive parsing, although the PC of Cache should stay "alive": shouldn't in this case an exception being thrown? Another problem is what to do when the Cache bean is passivated. Currently I get the exception:
"passivateEJB(), Exception caught ->
java.io.IOException: java.io.IOException
at com.sun.ejb.base.io.IOUtils.serializeObject(IOUtils.java:101)
at com.sun.ejb.containers.util.cache.LruSessionCache.saveStateToStore(LruSessionCache.java:501)"
Hence, I have no Idea how to implement my cache.. Can you please tell me how would you solve the problem?
Many thanks!
Bye

Hi Chris,
thanks for your reply!
I've tried to add the following into persistence.xml (although I've read that eclipseLink uses L2 cache by default..):
<shared-cache-mode>ALL</shared-cache-mode>
Then I replaced the Cache bean with a stateless bean which has methods like
Genre findGenreCreateIfAbsent(String genreName){
Genre genre = genreDAO.findByName(genreName);
if (genre!=null){
return genre;
genre = //Build new genre object
genreDAO.persist(genre);
return genre;
As far as I undestood, the shared cache should automatically store the genre and avoid querying the DB multiple times for the same genre, but unfortunately this is not the case: if I use a FINE logging level, I see really a lot of SELECT queries, which I didn't see with my "home made" Cache...
I am really confused.. :(
Thanks again for helping + bye

How to disable App Caching in 10.9

Hi All,
As much as I think that the new memory management system in OS X 10.9 is a very nice idea, it really doesn't work for me because I have Virtual Machines stopping and starting and the despite the fact that they are only trying to pull 512MB each, the system just can't handle pushing that much to them.
Is there a way to disable this app/file caching and get back to something more to the style of the old memory management system - I really want to have FREE memory available for when I actually need it - I really don't care if free memory is wasted memory, free memory is what works for me
I have a Mid 2009 13" MBP with a 2.2Ghz Intel Core 2 Duo with 8GB of RAM
Any help would be greatly appreciated, I can't bear my system grinding to a halt with several servers running in the background - the sort of thing that it could handle just fine under 10.8 - also, downgrading is not an option for me!

Unfortunately, no - App Nap only applies to running applications, and saving processing power and thus energy, whereas the app preloading is all about being clever about which files are in use and keeping as many as possible crammed into the memory.
However, disabling app nap is a useful thing to know, thanks!

How to disable SSL v3 for sun os 5.6 (OAS 4.0.8), I am facing POODLE vulnerability issue?

my Website is hosted on Sun OS 5.06 (OAS 4.0.8) and using web server : Oracle_Web_Listener/4.0.8. Website is configured to use https for secure pages and it was working fine from last 10 years but suddenly i am getting complaints from my customers that they can not browse site on chrome version 40 and above and firefox 34 and above.
I searched for this issue and found that there is POODLE attack which may causing this issue. now the only solution i can see is to disable SSL v3 on server.
Can any help me out with the process or an idea, How to disable SSL V3 on this Olde server? its sun microsystem server.

Hi Aamir,
   This is old software, been a while since I saw one of these.
    Normally when SSL was setup there were two listeners, one with SSL and one without, in a different port, so you could try to find this second port, which may work without any need to change the configuration.
    Else, try to check on the OAS manager (Usually on port 8888), the HTTP listener -> WWW -> Network, if there is a setup only for the SSL port, you will need to add a new line, with the same configuration, but a different port and the security disabled.
    Also, there may be some setting on the application itself for the url path. If so, when you navigate in the application it will try to redirect you back to the SSL port. In that case you will need to figure out where to change that, which depend on the application itself.
   Found this page on google with the process to setup SSL on OAS 4.0, you need to do the inverse of step 5.
