JAR file cache

hi all.
i have a problem with jar file on web form. i create one jar file thru jdeveloper and write some code on keypressed event. after deploying this jar file in d:\orant\forms60\java and adding this jar file in formsweb.cfg file developer forms works fine. but the problem is after using this jar file i made some changes in the jar and deploy again in the same manner. but my developer form doesnt take the effect of the new changes. then i create new form and use the same file i surprised new form take the effect but old one not so i can change the name of the old form. after changing the name of the form it takes the effect. so how i can solve this problem bcz it creates problem when i'm using it in my live projects. how i can clear the cache for this jar file
thanks in advance
Shakeel

If you change the JAR file you can't just re-load in the browser, you have to exit the browser and start a new one, then the newer JAR will be picked up,.

How to determine the path of the jar file cache of javawebstart?

Hello, I need to know how to determine where the java web start application
file jar cache is stored on windows system hard drive.
I would have launch of the inner processes
I have need to know the path of file jar .
example if my application is myAppliation.jar
in code generic class of myAppliation.jar i have the command runtime
String strCmd =
System.getProperties().getProperty("java.home") + "\\bin\\java" +
     " -cp " +
     System.getProperties().getProperty("java.class.path") + ";"
     + " anotherClass.class ";
Runtime.getRuntime().exec(strCmd);
the anotherClass.class has need
of the contained library in myAppliation.jar.

Thanks i have tried this metod and function
java.net.URL resource = classLoader.getResource("myResource");
if (resource != null) {
String s = resource.toString();
if (s.startsWith("jar:")) {
int index = s.indexOf("!");
if (index > 4) {
String fileurl = s.substring(4, index);
if (fileurl.startsWith("file:")) {
String path = fileurl.substring(5);
// now path is the path to the jar file in the cache containing the resource
System.out.println("file jar: "+path);
}

JAR File Caching Issues

After the security update here, http://sunsolve.sun.com/search/document.do?assetkey=1-26-103079-1 any users referencing our applets do not use the jar files stored in cache if the DNS has changed. We use an akamai hosted solution for jar distribution (though this would also occur in any DNS load balancing situation) thus the IP is rather dynamic though the content is identical. As the security issues states, any Plugin versions 1.5.0_13 and above or 1.6.0_03 and above treat a new DNS as compeltely new jar files.
Has anyone worked through similar situations? This renders the caching almost useless and we have a rather thick applet (3 Mb total jar files) which is quite an impact for a customer that is often low bandwidth to download daily.
Thanks!

Recently I tried to used some robot tools to test our application for performance issue. During the robot testing, I acceidentally discover some difference for the jar downloading which cause the above mentioned problem.
At first, this http request has no problem and the jar file is NOT downloaded. Http server shows a response code of "304", meaning download not required.
http_request
"GET lib/posLookup.jar HTTP/1.1\r\n"
"Accept: */*\r\n"
"Accept-Encoding: gzip, deflate\r\n"
"If-Modified-Since: Thu, 05 Dec 2002 17:22:12 GMT\r\n"
"User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 4.0; T31246"
"1)\r\n"
"Host: defaulthost\r\n"
"Connection: Keep-Alive\r\n"
"Cookie: sesessionid=0001UULRZPFLU5IBRNBVHWUUAFI\r\n"
"\r\n";
Then after running for a while, the browser jumps into another page and finds that the same jar file "posLookup.jar" is required. It issue another http request to server as:
http_request
"GET lib/posLookup.jar HTTP/1.1\r\n"
"cookie: sesessionid=0001UULRZPFLU5IBRNBVHWUUAFI\r\n"
"User-Agent: Java1.3.1_02\r\n"
"Host: defaulthost\r\n"
"Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2\r\n"
"Connection: keep-alive\r\n"
"\r\n";
But this time the user agent becomes Java1.3.1_02 and the accept type becomes text/html instead of original zip format. After this, I check the IE temporary file and found that the posLookup.jar is having a type of "HTML Document" instead of "Executable jar file".
Does anyone know whether this is a bug of the Internet Explorer or it is bug of the Java Plugin?
Appreciate any opinions or comments.
Thanks

Jar file caching problem

I'm running applets under IE in our application. The application contains multiple pages, each page with one applet. Each applet contains some shared jar file and one specific jar file for that applet.
Most of the time, the caching mechanism work fines. The browser is able to check with the HTTP server to see if any new jar files and download automatically. If no updates, the cached jars (in browser) are used.
However, at some other times, when I jump across several pages, performing different processing, suddenly the browser will reload all the jar files from the server. Even some shared jars are reloaded in every page within the same browser session.
If above problem occurs, I close the browser, open a new one and jumping to the pages again, the browser will be able to use the cached version again.
The runtime environment as follows:
JRE 1.3.1_02
IBM HTTP server 1.3.12.6
IBM WebSphere Appl Server 3.5.3
IE 5.50 (The "Check for newer versions of stored pages" is set to "Every visit to the page")
Pages created by JSP, syntax as follows:
<OBJECT classid="<%=JSPUtil.getClassid()%>" codebase="<%=JSPUtil.getPluginCodeBase()%>" WIDTH=100% HEIGHT=175% NAME=posApplet>
<PARAM NAME=ARCHIVE VALUE="<%=JSPUtil.getSharedArchives()%>, <%=JSPUtil.getArchiveLocation()+"/posPending.jar"%>">
<PARAM NAME=CODE VALUE=ho.aia.pos.pending.applet.PendingSGP >
<PARAM NAME=NAME VALUE="PendingRequirement" >
<PARAM NAME=codebase VALUE="<%=JSPUtil.getCodeBase()%>">
</OBJECT>
Do anyone knows anything about the problem?
Anyone knows how to make the caching work NORMALLY?
Thanks

Jar file caching on startup

Recently I've heard that NetWeaver, or to be precise the J2EE engine, is loading all jar files into an internal database at startup time. After that if the J2EE engine restarts, it checks for all saved jar files if the newest version is loaded.
It's as clear as daylight that this loading and checking is very time consuming and thus I want to know if this feature can be tweaked in anyway (cause my development NW takes so much time to startup -.-)
Anyone heard of this feature and/or can give any hints where to find a technical documentation?

Hi, you could try to disable the bootstrapping at startup.
Maybe that helps and will bosst up the starting process a little

Jar File caching in temp directory problem

Hello,
I have a problem where the java plugin is caching jar_cache9999.jar (where 9999 is any number 0-9) files in the temp directory. I have tried following the directions for disk caching in the documentation, but these files are always created, never destroyed.
I was wondering:
1. Is there a simple setting that I could set that should resolve this problem? (un-setting "cache jars in memory" wouldn't seem to solve the problem as I would think that would only force the browser to use the same jar if it had already been loaded)
2. Has this problem been corrected in later releases of the java plugin? I am using the jre1.2.2. When I looked at the problem here in the forums, the bug that was listed was listed as fixed.
Thanks,
Dan Hughes

Hi,
Java Plug-in has supported disk caching in previous versions by using the same cache the browser uses for all other web documents. This works for casual applet usage, but larger applets can often get flushed from the cache to make room for other documents since the browser has no knowledge that an applet file might be needed in the future. The result is that this caching strategy fails where is needed most in large business applets.
From 1.3. the new feature is activated by including the new "cache_option" , "cache_archive" and "cache_version" values in the EMBED/OBJECT tag that specifies the use of Java Plug-in as below:
<OBJECT ....>
     <PARAM NAME="archive" VALUE="...">
     <PARAM NAME="cache_option" VALUE="...">
     <PARAM NAME="cache_archive" VALUE="...">
     <PARAM NAME="cache_version" VALUE="...">
</OBJECT>
or
<EMBED ....
     archive="..."
     cache_option="..."
     cache_archive="..."
     cache_version="...">
For detail description please go through the following URL:

Hope this will help you.

Jar file is not cached

Hi,
I have a problem in caching the jar file. When the browser was closed and then open again, it tries to load the jar file from the web server again. It seems the jar file is never cached in the Java-Plug in. Here is the code for the page:
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
width=80% height=70% hspace="10" vspace="10" align="middle"
codebase="http://java.sun.com/products/plugin/autodl/jinstall-1_4_2-windows-i586.cab"
standby="Please wait...">
<PARAM name="type" value="application/x-java-applet">
<PARAM name="codebase" value="/">
<PARAM name="cache_archive" value="w1.jar">
<PARAM name="cache_option" value="Plugin">
<PARAM name="code" value="Proteus.class">Web Motion Control Applet</OBJECT>
Any idea?
Thanks for the help!

Have the same nasty issue here - beginning with 1.4.2 we see that the java plug-in add
Cache-Control: no-cache
Pragma: no-cache
to the HTTP request when downloading the JAR file (also happen when JAR is already in local plug-in cache). Therefore the web server always sends a HTTP 200 with full content instead of a lightweight HTTP 304 Not Modified.

Is there a way to disable the explicit "no-cache" request?

JRE won't cache some jar files.

I have seen this behavior several times and cannot figure it out. For some reason, the JRE will not always cache jar files. I have tried to narrow down a pattern, but cannot. The closest pattern I can see is that on occasions when a jar is not cached, the file was not signed. I have not seen an instance when a signed jar would not cache. Having said that, occassionally, unsigned jars do appear to be cached.
This behavior has been seen with all versions from 1.4 - 1.6. In all cases, the max cache size is far great than would ever be needed and in most cases, jar cache is cleared prior to testing.
Any hints, or is this expected behavior? If expected, is it documented anywhere?

Hi Matthew,
I get the same error when using the Camino browser and StuffIt v9.0.1. So, I'd guess it's a problem with the file rather than anything on our machines.

Turning off jar cache causes classnotfound with signed jar files

Hi,
I have a problem with applet signed jars when the java cache is turned off.
With the cache turned off, I get a class not found for the first class it attempts to use from the signed jar file from an applet.
If I turn the jar caching on, all works perfectly with no other changes.
Anyone have any ideas? This is java 6u16.
Thanks

Cached jar files

Hi.
I am in the middle of java bean development. As I have to test the java bean I often change the java code, comple it, jar compress it, sign the jar file and put it on to the application server $OH/forms/java directory. The problem I am facing is the JRE on the client side does not refresh / download the newly created jar file. To force the JRE to download it I have to manually delete it from JRE resources.
I was convinced every time the jar file is changed (date, length ...) the client JRE deletes old resource and downloads the new one. Now I am confused what I could be doing wrong.
Best regards, Gregor

Assuming you are using a new version of the JRE (1.6.0_22), so as to be sure you are not dealing with a bug, the JRE will reload the jar if it has changed. However, if the previous session has not been terminated this may not occur. Simply exiting the browser may not accomplish this thanks to changes in IE by Microsoft, which can cause iexplore.exe sessions to continue even though the browser has closed. The best way to know if the session has truly terminated is to review the System tray (next to the clock - lower right corner). If the Java icon is still displayed, the session was not terminated.
As for your immediate situation, I would recommend disabling caching while you are testing. This will ensure that the current file is always pulled from the server. Set the cache size to 0 in the Java Control Panel (Temporary Internet Files...) and uncheck the box labeled "Keep temporary files on my computer".

Why is the application caching the old jar file

Hi all
I have an application that is caching the old jar file.
even when i reboot.
when the application starts up it appears to pick up the old jar file.
any idea on how i can let it pick up the new jar file ?
stev

I'm pretty sure that it is just this one .jar file.
You see I changed a Servlet class in the jar file and messed up the application.
Now I'm putting back the old jar file and guess what
it's somehow hanging on to this old servlet class. and showing the same error. What is unique is that I did the same thing on another PC a server edition and it let go of the old Servlet with no problem
but on my PC a professional edition it is hanging onto that old Servlet even though I deleted every instance of it on the PC , shut down the PC and restart the app. I even deleted the old jar file from the recycle bin. the jar file has a very distinct name so i can easily search for it and
This app uses tomcat as well - not that that's related.
I have had this problem happen to me before at home with applet. I would change something and it would just hang on to it forever.
Anybody has any idea how to go into the registry or some other place and get rid of this servlet class or jar file ?

Pre-Deploy JAR files to JRE Cache in Windows

We are looking to build an SMS installer to pre-deploy all controls for our application to our end-users desktops. The application is Siebel.
Several of the controls are in JAR files and we want to pre-deploy these into the Java Cache via the SMS installer, as we block all control downloads from websites (both internal and external) including JAR as a matter of security policy.
The JAR files look like they should go to
C:\Documents and Settings\WindowsUserName\Application Data\Sun\Java\Deployment\cache\javapi\v1.0\jar
but there appears to be associated files that we can't create.
How can we do this? Any guidance appreciated.
We are currently using JRE 1_4_2_06.

Who knows where does IE6 cache jar files?

who knows where does IE6 cache jar files?
I don't know why IE6 can't show my new version applet in jar file.I have try to delete all the temporary file by use tools->options->delete temporary files.but it does't work.who can tell me what should i do? thank you,

Well in that case...I would hope it was cached in the browser...did you look at objects in the cache in (Tools, Internet Options....) in IE?

Jar File Class Caching

Hi,
I am having a problem with Weblogic 5.1 with Service Pack 5 and 6 and the deployment of jar files. I have my classpath set so that deployed classes can be found in the weblogic\myserver\serverclasses directory and I explicitely say weblogic\myserver\serverclasses\mybeans.jar for every jar I have.
Everything was working smoothly unitl I pushed out a new version of my jar file which had some minor updates to one of my beans. Weblogic was recognizing changes to the jar(after a shutdown and start back up), but then it suddenly stopped. I can't even see simple System.out statements placed at the beginning of my methods. Other changes to other classes in the jar are being accepted, is there something I am missing or is there a bug in weblogic that can get fixed with a particular service pack?
Here is the only difference from the class in the jar that is not being reloaded than those that are:
public static final String[] getList(String id) {
String[] aList = new String [4];
//do some lookup and set the array
i.e. aList[0] = someString;
ect....
return aList;
The above works fine.... but adding a simple System.out or creating a new local variable does not take affect. I checked the jar file and the class does include the changes.
Thank you, any help will appreciated.

Your question isn't very helpable either. You try to "access" this jar file from another computer? Exactly how? Did you mean it to be an applet, or are you trying to use Webstart, or what?

How to authenticate a JWS Client download of jar files on a web server

Here is a history of how i tried to implement the auth system:
The resources(jar files) cannot be downloaded by any HTTP client from the server without some authentication method.
As JWS is not reliable when using cookies (only 1.5 supports them, but with problems when in JNLP file i specify j2se version=older that 1.5) , i implemented another mecanism that works like this:
1. 1.The template JNLP looks like this
<?xml version="1.0" encoding="utf-8"?>
<jnlp codebase="http://10.3.0.62/" href="mapped/#JWS_CODE#___#PLATFORM#___app2.2.jnlp">
    <information>
       bla bla
    </information>
    <security>
        <all-permissions/>
    </security>
    <resources>
        <j2se version="1.4"/>
        <jar href="http://10.3.0.62/mapped/gui.jar?jwsid=#JWS_CODE#" version="2.2"/>
        <jar href="http://10.3.0.62/mapped/data.jar?jwsid=#JWS_CODE#" version="2.2"/>
        <jar href="http://10.3.0.62/mapped/log4j.jar?jwsid=#JWS_CODE#"/>
    </resources>
    <application-desc main-class="com.bet.blues.gui.Application">
        <argument>-host</argument>
        <argument>ursus</argument>
        <argument>-port</argument>
        <argument>17771</argument>
    </application-desc>
</jnlp>2. All resources found in /mapped/ directory are mapped to JWSServlet
3. The users login to a site , clik on link , /mapped/app2.2.jnlp , the servlet checks if the session is active , gets the PLATFORM form browser request header , gets the JWSCODE for the logged user, replaces this in the template, and returns it to the client
4.Now after the 1st download the JNLP file is opened by JWS Client , that checks for latest version , requesting the JNLP file again
like this:
GET http://10.3.0.62/mapped/f12ks21092___windows___app2.2.jnlp5.Now the servlet sees the the request has a JNLP file name with an ID and PLATFORM, and serves the JNLP as before
6.The JWS Client will request for JAR Files
GET http://10.3.0.62/mapped/gui.jar?jwscode=f12ks21092?version-id=2.2Note: that i have forced JWSID parameter in the URL, that's why the query string contains 2 "?"
- forcing this is because the mapped/*.jar is redirected JnlpDownloadServlet that supports versions , diffs - i cannot use 'version' to put there the jswid param(e.g .../mapped/gui.jar version="fk12ks21092_2.2" because the JnlpDownloadServlet will not find this version , and if JWS Servlet will redirect to JnlpDownloadServlet with correct version param in request, the JWS Client will raise an exception because version responded is not right(JNLPDownloadServlet marks in response HTTP header the version of the jar so JWS CLient will chek it)
JWS Client expects version 'fk12ks21092_ver2.2'; to correct this i should modify the JnlpDownloadServlet and i shouldnt
THE PROBLEM :
on older versions than 1.5 JWS Client raises an exception because it wants to create a temp file named
" gui.jar?jwscode=f12ks21092" because it contains "?"
Only with 1.5 that seems to parse the jar name until it meets "?" char :(
Thats why i wanted to send an error to the client to upgrade to Java Web Start 1.5
Now, maybe u have a solution to this problem...
All i want is a solution to let JWS Client download jars only if the user is authenticated by some mecanism....and also support the versioning system.
Also:
Note that the jar names must preserve on the client JWS Cache dir ( i cannot use the same method to pass the JWSCODE when requesting the JARS as when requesting the JNLP).

You need to look into JAAS
