Signed applet and HTML parameters

I've created a signed applet and everything works fine, except for the fact that i can't add parameters to the applet.
Without the parameters in the HTML the applet inits and starts and can be used without problems. But when I add paramaters, the applet reports a "class not found exception".
I used HTML-converter to convert the applet tag to object/embed tags.
Has anyone had the same problem or knows what I'm doing wrong? I'd really appreciate some help.
Thanks in advance,
Erik

Include many jars for a complex signed applet in html file??

hello
I'd like to know how it's possible to put a signed applet in an html file, that needs many jar files.
I explain myself: I know that to create a signed applet and to put it in an html file, I need to create a Jar file that contains this applet, create a private key with keytool, sign the jar and include it in my html file with the tag <applet code="....." archive="......jar".... />
This works fine if my applet is a simple program that only uses the clases present by default in the jdk.
In my case, I have a big project, with many packages. In one of these packages, I have my applet that uses some classes of the other packages, which use classes from imported jars, such as BouncyCastle, and others...
There is still no problem when I run the applet from the applet viewer.
The problem appears when I put the JAR file with all these classes in the html file: there is a problem since it doesn't know anything of these classes imported from these jars.. It's quite obvious actually.
My question is: how do I do to make the html file aware of these classes? Is there an html tag that allows us to include many jar files? Do I have to decompress all these jars, take all the directories, add them to the directories of my project and create a BIG jar (that's what I did, but it's really dirty, and heavy! (11M))??
Does anyone have an idea about how I can do it?
Thanks for your help
Philippe

11 MB is pretty big for an applet.
Let's say your applet uses java 3d, normally a client would download and
install this seporately, meaning the jars needed end up in lib/ext directory where
any applet can find them.
Check what applets need to be installed (put in lib/ext) and what can be
downloaded:
<object .....
<param name="archive" value="myJar.jar, myOtherjar.jar" />

JRE 1.4.x Plugin - Signed Applets and Weird Behaviour (Policy)

Hello.
I have recently experienced some strange behaviour related to signed applets and policy files in JRE 1.4.2-b28 ( a friend got the same behaviour in a flavour of 1.4.1-xx as well ). Both tests were on Windows 2000 Professional platforms.
Initially my unsigned applet, which attempts socket connections to a server different from the download location, fails with security exceptions ( as expected ). Then I did the following to sign the applet jar and configure my environment
Steps: 1) Import "trusted CA" certificate into ${java.home}/lib/security/cacerts. (JRE home outside the JDK)
2) Signed the jar using jarsigner and a certificate generated from the "trusted CA" (Entrust CA and certificate).
3) Imported the signing certificate into the Java plugin using import in the plugin control panel.
4) Created a new keystore (keytool,jks) and imported the signing certificate into the keystore with alias "developer". The keystore is stored in the user home as .keystore.
5) Created a .java.policy for the user and attaching the keystore in 4) to it. ( also stored in user home ).
6) Used the policy tool to grant socketpermissions to the specific codebase ( testing with file:/C:/test/* initially ) signed by "developer"
After this, when I ran the test page under IE 5.5SP2 and Netscape 7.1 it worked without any security exception. Ditto for using the appletviewer and the policy file I created for the user.
The weird part occurred when I removed the policy entry from the user policy file. After doing this, Netscape and IE still allow the applet to execute - somehow remembering that it was granted permissions at some point. The appletviewer does not allow it to execute, generating security exceptions.
It appears the old policy is being cached somewhere, but I cannot find where. If I replace the applet jar with an unsigned version it does fail in IE and Netscape. I tried cleaning the plugin cache and removing the "deployment.certs" files related to the users but still get the same behaviour.
Does anyone know where the old policy information is being stored ? Does anyone know how to revoke the permissions so that I am restored to my original base environment ( no permissions for "designer" signed applets ) ? Would attempting to utilize the AccessController.doPriveleged( xxxx ) operations in JDK 1.4 avoid all of this confusion with policy files, keystores and certificate storage ? After all the messing about I would like a zero-footprint alternative ( or minimzed footprint anyway ).
Any ideas would be most welcome.
Regards,
James.

Hello Again.
I am either enlightened or confused at this point. I found that as long as all of my related Jars are signed ( even by self-signed certificates ) I am granted SocketPermissions for calls outside of the originating server. Unsigned code is refused, but even when the Jars were signed using a self-signed certificate the Socket calls were allowed.
Am I experiencing the appropriate behaviour in this case ( which would mean not having to utilize policy files to distribute an applet that uses calls to arbitrary servers - e.g. JavaMail ) or am I suffering from something damaged in my environment ?
It has been a long time since I played with signed applets and I am having difficulty determining what operations require policy file entries/AccessController.doPrivileged() calls and which are granted when a user elects to trust a signed applet without policy.
Any assistance in clearing up my confusion would be appreciated.
Regards,
James.

IIS, Javascript, Signed Applet and ASP Blank Page Problem

Hi,
I'm having a problem using a Signed Applet in a site that runs in a IIS (Windows Server 2003).
My aspx web page uses the applet to read my smart card and get information from it.
This applet uses an auxiliar dll (stored in a second Signed Jar file) in order to read the information from my smart card.
The way the solution is design:
1) Aspx page is asked from server
2) Internet Explorer recieve the page and asks the server for it content (images, applet, javascripts, etc)
3) After this the JVM runs (console opens)
4) After the Aspx page render fully a javascript register onload fires and call an applet method
5) Applet receive the call and run the logic of the method:
     - reads the smart card;
     - calls Javascript function in order to fill aspx fields with information from smart card
     - calls Javascript function the simulates a click in a botton of aspx page (in order to call server side part sending data readed from smart card to server)
5) The server makes some logic with the information receive and responds to client registering in aspx page a call to another Javascrit function
6) The client received the asnwer from server and runs the Javascript function registered on step 5)
     This Javascript calls another method from applet and runs the following logic:
     - reads more information from smart card;
     - call javascript function in order to fill more fields of aspx page with the information readed
     - calls Javascript function the simulates a click in a botton of aspx page (in order to call server side part sending data readed from smart card to server)
7) The server makes some logic and call another pages with no Applets
8) Client asks for a second page with the same applet and we start with another logic express on steps 1);2);3),4);5) and then 7).
This is all ok, until sometimes the server stop responding correcly for requests regarding this two pages with the Applet.
When this happens the server just responds with a blank page.
     - with fiddler I can seer the request for the aspx page (that uses the applet)
     - but server responds with a blank html page
The JVM doesn't fire.
The IIS log don't show errors.
The eventviewer doesn't show errors.
The problem is solved with an IIS reset or a Application Pool reset.
After a while the problem returns.
This problem occours for other user in another machine, the server just stops responding correcly to request regarding pages with applets, the other pages still continue to work.
If we disable Java Control Panel->Advanced->Java Plug-in->Enable the next-generation Java Plug-in the problem seend to stop, but we can't force all clients to disable this option right?
Or there is a way to force the Applet to run with this option disabled?
As anyone experience similar problem?
Regards,
OF

This is all ok, until sometimes the server stop responding correcly for requests regarding this two pages with the Applet.

- with fiddler I can seer the request for the aspx page (that uses the applet)
- but server responds with a blank html pageWell, if http requests look identical in case of success and failure (pay attention to cookies, etc) then it has to be something on the server side.
It could be that server gets into this wrong state because of previous requests made by applet but it is hard to tell.
I am not clear how old/new plugin can make a difference unless your applets run in the legacy mode (i.e. you are actually trying to reuse SAME instance of the applet when
it is loaded next time).
I'd start with
1) carefully comparing good/bad sessions
2) checking whether server will serve correct response to another client when it serves "bad" page for current client
3) add debug statements to aspx - it is scripted page, may be some condition is not met and then it returns blank?
4) record all http requests in one session until you get to "error" state and then use any http server testing tool to "replay" this set of requests.
You should be able to get server into the same state without use of applet. Then you can try to tweak set of requests to see what makes a difference.

How to create signed applet and make it work with browser

i hav an applet that needs to write a file to onto local system resource. i came to know that the applet needs to be signed. so i searched some guides to create a signed applet but most of them specify how to use it with applet viewer and not on a browser. plz help me with how to sign an applet and and allow it to write a file from within a browser.

On linux, something like this:
keytool -genkey -alias signSocket -keystore socketstore -keypass abc123 -dname "cn=your name" -storepass abc123
jar cvf Socket.jar *.class
jarsigner -keystore socketstore -storepass abc123 -keypass abc123 -signedjar SSocket.jar Socket.jar signSocket
And in html:
CODE = "YourClass.class"
ARCHIVE = "SSocket.jar"

Signed applet and security; a question

I was wondering if you somebody has any experience packaging a signed applet within BEA? If so, Im wondering if I could ask you a few quick questions regarding MYAPP.
MYAPP uses an applet that needs to be signed. This applet makes use of an external library for some of its client screens. Currently, I have packaged the applet classes, including the library contents as part of the root in the war file (i.e. exploded out of their archive and simply placed in the WAR file as fully path qualified classes).
To sign the applet normally you would sign the jar file in which the applet is contained. But, when I place the jar file in the WAR file, the client cannot find the applet, even with the codebase and archive attributes filled in on the HTML page.
My questions are as follows:
Is there another mechanism for me to package the applet within the EAR file (i.e. a CAR file instead of the WAR?) such that I can package the applet within its JAR files and sign the JAR as I normally would?
In lieu of anything on (1), how do I sign the applet? Should I be signing the WAR file or the individual classes?
Please let me know if you would bee able to help, thanks much and again.
Best regards,

Thanks.
The only server available we have is BEA 81 sp3
appserver. We are not using webservers so we have to
stick to BEA. Either it has a webserver included or you're screwed.
Moreover, MYAPP.ear contains a huge amount of other
JSPs and other stuff. My goal was to create a SINGLE
ear file with MYWEBAPP and MYAPPLET contained in the
same EAR file ?The point is that you have to point your applet's code base to a directory on the webserver. With dynamic web-app mapping and stuff you might not know where that is.
So, is it doable to contain both MYWEBAPP and
MYAPPLET in the same EAR file .... please correct me
if iam wrong ?http://info.borland.com/techpubs/jbuilder/jbuilder9/webapps/webapps_context.html

WebService call from signed applet and MS Vista

Hi.
I'M developing a system that needs to call web services from a signed applet.
I have made the solution like this.
The applet starts by checking that the 12 needed libs is present under the <java home>\lib\ext folder. if not it will download the files automatically and restart the browser.
This works fine in Windows XP because the signed applet gives me read/write access to the whole machine, but in Vista this isn't possible anymore (as i understand it).
My question: Is it possible to put these libs in another folder that the ext lib? I have tried to define the "archive" tag in my Object tag but i get the class not found exception thrown in my face.
If there is a solution to this i would very much like some pointers!
If not what can i do to get access to the <java home>\lib\ext folder under Vista?
Regards
Michael Pallesen

When invokin applet methods via javascript, you are accessing privileged actions from an unsafe source.
Depending on your needs, you could either load the system variables in applet init into class variables and return the information contained in the class variables to javascript or wrap the method calls inside AccessController.doPrivileged() calls.

Signed applets and dialogs

hi all,
question to clarify my understanding of signed applets.
got a bog-standard applet. nothing clever or special.
got myself a bog-standard cert from thawte.
signed the applet and put it on a webserver.
displays the correct security notice on first load. continue and "Always trust this company" etc...
all runs fine.
in the applet init, i've put in
java.awt.AWTPermission perm = new java.awt.AWTPermission("showWindowWithoutWarningBanner");
try {
AccessController.checkPermission(perm);
System.out.println("access allowed?");
} catch (AccessControlException ex) {
ex.printStackTrace();
}open the main frame, and all is good. no banner or access denied exception.
show a popup menu, or tooltip. no banner.
display a dialog. oops, a banner "Java Applet Window" and the bottom section of the dialog is covered with the warning msg.
so i'm confused.
does this mean that this permission does not apply to dialogs? (if so, what?)
even with a cert, this msg cannot be removed? (please tell me no)
wrap and recode all dialog openings with AccessController.doPrivileged? (i dont wanna do this)
or i missed something with the setup.
i've been searching the forums for some info, but seem to be going in circles. editing the policy file on all client comps is not a valid option, unless there is sometrick i dont know about .

Signed Applets And IE Security

Hi, all!
I have a signed applet (x.509) run in IE with plug-in 1.4.0b92. In most cases the behavior is as it is expected - a window prompting user to deny, allow or always alow the certificate in the applet appears. But there are some cases when this window doesn't appear and the users are able to run the applet. No certificates are previously installed or granted(at least there aren't any items in Certificates tab or in .keystore file in user home).
Does anybody could say what is the normal behavior of the plug-in - does it always prompt the user when a signed content is run; does it depend on Security setting in the browser?
Thanks in advance for any help or further information!
Regards, Ivo Kolev

Hi,
Do you clear you Plug-in Cache explicity ?
May be sometimes your IE uses the plug in to restore the applet from the cache.
But I remember having observed the same problem when I used a signed applet. The dialog box appears 'mostly always' but sometimes it just doesnt :)
if you are able to resolve the problem...let me know

Applets and HTML 5 Offline Cache

Hi,
We're doing some tests with offline application caching in HTML 5 (using Firefox 3.5 for testing).
We can get our basic app to work offline, but the Applets refuse to load from the offline cache.
You can see the demo here: http://3d-lab.aarkid.com/playground/html5/
Just enter a message and it will appear in the two applets and in the HTML below (there are two because we initially thought it was a problem due to the middleware we were using, so there's a basic Applet there too). You will need to wait for the Applets to load before the controls appear.
Now, when offline (completely offline, no Internet connection at all) the Applets are trying to load the class from their online location rather than using the cached version. (console output below)
Is there any way to tell the Java Plug-in that it's offline or where to load the classes from?
Thanks.

Out of curiosity. What is it you can do with JS that cannot be done with an applet and an active server (e.g. something that can run PHP, JSP, ASP..)?We require the app to run completely offline (or rather, the client does) (i.e.) no Internet connection. We have tried giving them an install with a portable apache and PHP, which has worked in the past but not for this client. So we were attempting to use HTML 5 for storing data offline, but the lack of support for offline caching in the Java Plug-in is the only thing holding us back, I guess we'll just have to wait for Sun to catch up :)

Signed Applet and native code

Hi all,
I have an application which I deploy with webstart and includes native code. This all works perfectly with webstart. I now want to deploy it as an applet. This works accept for the native code. I have done heaps of searching and cannot determine the most appropriate way to make the native code visible to the applet.
Ultimately I am at the point where i recieve a UnsatisfiedLinkError when calling loadLibrary(...) for the native code. Currently i have the native code (dll's for windows, so's for Solaris etc) in independent jars which are also signed (as needed for webstart).
Could anyone give me some advise or a reference to more info on this topic.
I am using Java 1.5 and am happy to use 1.6 if neccessary.
Thanks,

Andrew - of course you were correct about the signed cert - I misspoke when the CA signed applet didn't show a warning. (You were also right that I must have checked 'always accept' the certificate on the server I had the CA signed cert on).
I think you guys are on to something about the privileged actions. It would explain where one popup has the icon and the other doesn't. We have Javascript making calls into the applet and we do use JNI (although I don't think there are any calls back). We do wrap these calls in privileged actions but maybe we missed something. What I've seen before is a security exception is thrown if we don't wrap them - but maybe there are areas where we don't and it doesn't throw an exception or it does and we eat it somehow (and for whatever reason doesn't cause anything noticeable).
Now that I know it could likely be the applet code and not necessarily a build issue with signing the jars, I have another place to look...
I'll check it out and let you know what I find.

Signed applet and database connetion...

Hello,
Well, I am deploying an applet application which needs to connect with a postgres database.
I put my application in my hosting then I changed my local java.policy file adding a line as
permission java.net.SocketPermission "127.0.0.1:5432", "connect,resolve";And my applet works... but I don't want that the user needs to change his policies file.
I read in somewhere in the forum if the applet is signed the user doesn't need to change anything... then I sign the applet. But it doesn't work. It looks to me that signing the applet is not enough to allows the connection.
But I don't sure.
Some body had had the same problem or am I doing some thing wrong?? Other Ideas
By the way, sorry for my bad english, I hope you can understand what I am saying.
Bye, and thanks by advance

Thanks for the answer.
That's a good test, I put some code before the DB connection to create a file:
              File file = new File("tavo.txt");
             boolean success = file.createNewFile();
             if (success) {
                  javax.swing.JOptionPane.showMessageDialog(null, "YES");
                 // File did not exist and was created
             } else {
                  javax.swing.JOptionPane.showMessageDialog(null, "NO");
                 // File already exists
             }And surprisingly it creates the file. but doesn't connect to the database.
I Sign the applet by command line, like this:
keytool -genkey -alias signFiles -keystore compstore -keypass pass -dname "cn=salazar" -storepass pass
jarsigner -keystore compstore -storepass pass -keypass pass -signedjar Sproceso.jar proceso.jar signFiles

DB connections are not prohibited as such.
What is prohibited are Socket connections, which DB connections use internally.
Therefore, if any of the classes on the stack, when the Socket connection occurs
is not from your jar, it will fail. Therefore, the 3rd party files must be all in your jar.
Technically, this is easy: explode their jar and create your jar in such a way as to contain
all the files from their jar as well. Do it just as an experiment. If it works, read well
their licensing terms, which may forbid this. If they forbid it or if in doubt, contact them.

Signed Applet and page reloading

Hello,
I'm having some troubles with an applet i've developped. It serves listening on the serial port, so i had to sign it and that's what i've done. Right.
Second i put it in a page with the deploy.js from oracle with a jnlp. The applet works, run on the first time... But when i go on another page the applet doesn't standby but destroys itself ! And when i return on it the applet initializes again !
What i want is the applet loads the first time and stay loaded on background until the browser is closed. So i'd want run it a first time, change the page and return on the applet's page without initializing again.
Do you have any ideas ?
Thank you !

Erf , so how could i do that... What i don't understand is that everywhere i saw tutos about applets everybody talked about init() launched ONLY on the first time and then start() every time the user comes back on the page. ..I am pretty sure you have it wrong. <tt>init()/destroy()</tt> are called on page entry/reload & exit, while <tt>start()/stop()</tt> are called if the browser is minimized/restored, or maybe if changing between tabs (I'd have to check that).
Ultimately though, there had been problems with browsers entirely failing to call the <tt>destroy()</tt> method, or implementing their own decisions about when to call <tt>start()/stop()</tt>. I would not rely on any specific behavior for them.

Signed Applet and Bluetooth

Is it possible to establish a bluetooth connection with a signed applet?

Try this:
OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
WIDTH = "600" HEIGHT = "400" codebase="http://java.sun.com/products/plugin/1.3/jinstall-13-win32.cab#Version=1,3,0,0">
