Java cache

Where can i find the java-cache of the internet-explorer. What i mean is where does i-explorer store the class file loaded from a website. I need to delete a version of my software in order to load the latest version. Once loaded, it doesn't reload the new version if avaible...
tia...

So instead of using IE to search the web, you just keep posting here and waiting for an answer?
This took me 1 second to find (at the bottom of the page):
http://homepage.eircom.net/~pugsleypaul/java/applets.htm
is there a way around this problem???Get up, turn off the computer and don't return to the chair - ever.

Java web start fails to launch application when java cache is off

Hi,
there's no problem when java cache is used but when java cache isn't used, my application fails to launch via jws (jnlp).

JRE : 1.6.0_19

I checked for other versions of jre but not using java cache didn't cause any problems.
I checked for the release note of update 19 but I have no clue.
Is there any way to launch java application without using java cache?

..I had a problem changing the cache location. The button for this action is disabled. I can't figure out how to enable it.On my system, it is enabled when the 'cache files' box is checked, and disabled when it isn't.
1) Without changing the location I assumed that deleting the cached files could be a similar job, so I clicked "Delete Files..." and deleted with all checkboxes checked.I am not convinced that would entirely clear the cache, but have done no specific tests to check.
2) I unchecked "Keep temporary files on my computer".So it was checked when you were trying to change the cache location?
3) Applied all the changes.
4) I launched your demo.
Result - It was launched without any prompt.
I revisited the page with the URL and successfully launched the app. again.The application launched just fine, but no prompt.
If you follow those (links and) steps I outlined exactly, does the file service demo launch twice for you?I'm sorry I don't exactly understand your question. .. Your description is enough to convince me that answer is 'yes'.
..I tried twice and it launched twice, but not twice at the same time(it launched once at a time).Surprise, surprise. That is the first mention in this thread of 'same time'/'simultaneously'. Care to share the other defining factors that you forgot to mention, or is guessing part of the 'fun' of helping?
But still I'm having problems with launching my application.
I assume that it could be jnlp syntax problem. The "main=true" subelement is missing.It is a good idea to validate the launch files of JWS based launches that are failing for any reason. For that purpose, I offer JaNeLA.
Having said that, a missing main='true' will not be detected by JaNeLA, since it is not a compulsory attribute. ..But check them anyway.

Speed of animation fluctuates based on java cache..

Hi everyone,
It seems I am experiencing a rather weird problem.
In my app I am having a small animation on a BufferedImage using the swingx.Timer class.
The problem is that sometimes the animation runs very slow (I get a feeling of the computer struggling to keep up)
while some other times its running on full speed! (I have set the Timer constructor to 1ms)
What could be causing this "undeterministic" behaviour? I 've looked at the code a million times
and there seems to be nothing wrong with it...!
P.S I am having a CORE2DUO and running the latest JRE 1.6.024
UPDATE: I can replicate the problem if I clear the java cache from the control panel
in windows..!strange...isn't it?

Webutil_file_transfer url_to_client places objects in the Java Cache

Hi,
I'm using webutil_file_transfer url_to_client to download a PDF file.
Once I downloaded the PDF file, it is visible in the Client Java Cache Viewer. When I try to run the download again webutil takes the PDF from the Cache instead taking the newer PDF from the Server where the URL is pointing to.
So the URL I passing is each time the same, but the PDF file on the Server is getting updated very often.
I don't usethe WEBCACHE port!
My question now is. Can I avoid webutil to put does PDF file in the Java Cache on the Client. Or is there any utility to remove selected objects from the Java Cache.
Does anybody have a Idea how to avoid such a behaviour?
Fatih

Hi Craig,
with the help of Oracle Support, we found the reason and also a workaround for this issue.
The real cause:
By default the java applet parameter DefaultUseCaches is true an all files downloaded within an applet is going throug the Java Client Cache.
WEBUTIL does not touch this parameter, so it keeps staying default (true).
Solution/workaround:
With the methode setDefaultUseCaches it possible to disable/enable the default Cache setting.
So it's possible to disable the cache with a small Java Bean running in Forms, which disable the Cache before WEBUTIL_FILE_TRANSFER and enable it after the successfull download.
here is an extract of the bean code:
URL u = new URL( "http:" );
URLConnection uc = u.openConnection();
uc.setDefaultUseCaches(false);
thank you for your time!
regards,
Fatih

Value mapping replication - java cache

i used value mapping replication and successfully loaded values to the java cache (i can see the in the cache monitoring but not in the configuration).
when i try to use a scenario with value mapping using the agencies and schemes which i loaded, the mapping doesn't work and i receive the same value that was entered.
what could be the problem?
P.S
i used the same groupid for each pair of source and target value when i loaded them. is that the right way?

Tomer,
what is the context that u used. Did you give the correct context in mapping as in Runtime Cache.

Issue with Java cache

Hi friends,
I'm in PI 7.3 environment, my problem is - when I try to access ESB and IB, it says that it is Unable to download.
So, for that am clearing Java cache and trying to download to get into ESB and IB every time. Obviously am wasting hours of time to login ESB and IB. Just in case if the connection gets off, then If I want to get into ESB again I have to clear the Java cache completly(Java cache is not recognizing)
I came across all the links in sdn but not solves my issue. Kindly share exact to do things - to fix the issue.
Many thanks.
Swarnaalu.

Hi Swarna,
There might be some problem with javawebstart you can try uninstalling java and try to reinstall so that it will work.
OR
I am not sure in PI &.3 but in earlier versions you can do the re-initialization which works.
follow the below:
1. Login to your XI/PI server
2. Go to Exchange Infrastructure Tools main web screen. You will see
Tools list and other options.
http://SERVER:PORT/rep/start/index.jsp
3. On the Upper right part of your screen you will see Tools
Administration Client Installation and Guidelines Documentation.
Click Administration
4. Login with user.
5. On the Exhange Infrastructure Administration , make sure you are in
the Correct tab. (Repository Directory Runtime). The tab will
determine the administration configuration that your will perform
5.1 When this problem occur with Integration Repository > make sure you
are in Integration REPOSITORY TAB. Proceed with step 6. Skip step 5.2.
5.2 When this problem occur with Integration Directory > make sure you
are in Integration DIRECTORY TAB. Proceed with step 6.
6. Click on Java web start administration.
7. Click on Re-initialization and force-signing. This will
re-authenticate all new JAR files deployed. This will also let the new
JAR files adapt to the current certificate deployed.
This function will cause the above re-collection and additionally a
re-signing of ALL resources with a dummy certificate. The original SAP
signatures of the jarfiles will be lost. To get back the original SAP signatures
the application has to be deployed again.
8. A Java(TM) Web start Application reset text will appear.
9. Wait for 5 to 15 minutes for re-initialization to complete
10. Start your "Integration Repository' or "Integration Directory"
again. It should work now.
This will solve the issue

Naveen

Clear java cache

Hi
Hope someone can assist
I'm struggling to download items on some websites on Safari and the forum on the website suggested I clear my Java cache. I can't find any references to Java under system Preferences or Utilities. There is also no option to clear the cache in Safari.
I've cleared the history and the cookies but that hasn't helped either.
Can anyone point me in the right direction?
Much appreciated

Thanks,
For some reason I don't see Java under System Preferences?

Store XML data in java cache (hashmap as a key value pair)

Hi,
I have to store a xml file in java cache so that I can resue it .The flow is like this :
DAO layer reads database ,create an xml and sends to --> IBM MQ-->our java code should read this xml file over MQ and store it in a cache (preferably hashmap).The file contain unique id for every customer.
How can we achieve this.One way is to store the xml as an string as key is "id" and value is whole xml.Is this a good way or any other way is available.Please suggest.
Sample xml:
<Client>
<ClientId>1234</ClientId>
<ClientName>STechnology</ClientName>
<ID>10</ID>
<ClientStatus>ACTIVE</ClientStatus>
- <LEAccount>
<ClientLE>678989</ClientLE>
<LEId>56743</LEId>
- <Account>
<AccountNumber>9876543678</AccountNumber>
</Account>
</LEAccount>
- <Service>
<Cindicator>Y2Y</Cindicator>
<PrefCode>980</PrefCode>
<BSCode>876</BSCode>
<MandatoryContent>MSP</MandatoryContent>
</Service>
</Client>
Thanks
Sumit

A HashMap can work, but then still store the customer related data in a bean (and perhaps it will have some child objects as well, if for example the service subelement can repeat). So you get a HashMap of Customer objects, with the clientID as the index into the hashmap.

What are you caching and why?

Java Cache Viewer shows duplicate URL with different versions

In doing some testing lately we have come across a couple of situations where the same URL is showing in the JAVA cache viewer with different versions to them. In the case of a 1.7 JRE this is not causing any adverse effects however when utilizing a 1.6 JRE we are getting messages about mixed mode for the JAR files.
The jar file is signed as below:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.8.2
Application-Library-Allowable-Codebase: *
Application-Name: named_applet
Built-By: relbuild
Permissions: all-permissions
Created-By: 1.6.0_17-b04 (Sun Microsystems Inc.)
Caller-Allowable-Codebase: *
Codebase: *
understanding the need to change the wildcard's to domains as we move forward. I am wondering why the jar file is being listed and called twice and why it is being recognized as signed one time and not the next.
The URL is identical in the cache viewer and the java console says it is not found in the cache when it is used the second time, even though previously in the session is finds it with the correct version.
Any advice would be helpful

that i even know, but the problem is that i do not have that version of java re installed, but i found distribution 07 of the same java version, i'll try it out with that.
but when it still doesn't work, then i still would like to find the link where i can download java version 1.4.2_06.

Java Cache Issue on SAP MII 12.1 SP09 (Build 116)

Hi All,
Has anybody experienced this issue before?
Problem Description
This installation is a central MII instance, which is HP hosted in Swindon, UK. On Login we are experiencing a delay in loading the Java Applets, i.e. iGrids, iCharts, iCommands etc. After the first screen load the performance improves. When we close the session and re-enter, the performance on the first screen is delayed.
Problem Investigation
We have compared this project to other MII instances and investigated the cache loading of each of the MII installations. What we have noticed is that the Java is not being cached on the client side for the MII server V12.1 SP09 (Build 116). We had three MII servers, with this version, and we are experiencing the same issue. We have other instances of version 12.1.7, 12.1.8, and 12.2.0 and the cache functionality is working fine.
To view the cache we are opening the Java Cache viewer on the Java Control Panel, and we are looking for the file u201Cillum8.zipu201D which is the MII Java library. This investigation was done using the same Client Java Runtime version and IE Version.
Software Versions used: JavaRuntime version: 1.0.6_22 & Internet Explorer 8.0
Any advice/help much appreciated.
Regards,
Henry

Hi Henry,
Not sure this has any bearing, but what NW version and SP is MII sitting on top of?
Thanks,
Mike

Yes. Always keep the default settings unless you have a specific reason not to.
If you are a heavy user of Java programs or applets, you may need to clear the cache files after Java updates because the old caches may interfere.

How can I change the java cache path - jre v. 1.6.0_03 ?

Hello,
Computer with OS Windows Vista Pro & JRE v. 1.6.0_03.
Standard path for the "java cache" is: c:\users\PCV\AppData\LocalLow\Sun\Deployement\cache
Is it possible change it?
Many thanks for your feedback

The General tab, Temporary Internet Files, of the Java Control Panel allows this to be set.
I suspect that Vista's Security/ALC will be upset if you mode it to a different security zone, however.

How do I empty Java cache

I have an iMac running Mavricks. I play a lot of Pogo games and need to know how to empty my Java cache. Any suggestions or input will be welcome,
Thanks,
leonoraofarcadia

Jonathan,
Welcome to Apple Discussions!
Here's how to empty your Java caches --
Go to your Utilities folder in the main Applications folder.
Double Click on Java 1.3.1 Plugin Settings.
Select the Cache Tab.
Then click on Clear Jar Cache.
That's it.
Now do the same for Java 1.4.2 Plugin Settings.
If I were you, I would also clear the History from the main Safari menu,
Empty Cache from "Safari" (Top left of your Safari Menu)
and check the size of your Icons folder in
Home (Your Name)>Library> Safari folder.
If it's over 1 MB, put it in the trash and empty the trash.
A new one will be regenerated when you restart Safari.
Let us know how you're doing after this, OK?

Java Caching Framework

Hi All,
I m in process of evaluating some open source java caching framework which can help our web application to reduce response time.
Though i have some open source caching framework in my list like
JCS
OSCache
JOCache
But i have never used any one of the caching framework.If any one in the group have used them in past or is working on some open source based framework,please do share there experience so that it can help us in deciding the best available solution.
Thanks in advance

You may want to check out Hazelcast . It is an open source distributed, transactional distributed cache for Java. Hibernate second level cache plug-in is also available .
Hazelcast is released under Apache license. It also have distributed lock, topic, multimap, queue and executor service implementations. [This 10 minute video|http://www.hazelcast.com/screencast.jsp] is very good to get started.
