Signed applet, jmf.jar provided, but no connection

hi there!
i'm posting this again in order for you to earn duke-bucks.
i have a similar problem. i wrote an applet that connects to a video-streamserver an requests a live-stream. the applet sends some udp-packets to the server, which retreives the client's ip from the
packet and sends it back to the client ( i did this to avoid signing the applet, since otherwise the client
would have to do a dns-lookup and therefore be signed). the client gets back his public ip (i don't have the 127.0.0.1-problem) , however, i get an
InvalidSessionAddressException :
Local Data Address Does not belong to any of the local interfaces
it seems, the client cannot recognize it's own public ip.
so i thought, signing the applet would do, but it doesn't.
I get the same InvalidSessionAddressException.
now, this only happens on hosts on which jmf is NOT installed.
Installing the jmf solves the problem. but i don't want people who visit my page having to install
jmf in order to watch my livestream. i tried including the whole jmf.jar (also tried, customizing it),
but no success.
i read the posts on the issue: running jmf-applets on non-jmf-systems, but there seems to be a
controversy on wether that is possible or not. some say, jmf must be installed, some say, just include jmf.jar or customized jmf.jar.
what else could i try? i have the clients public ip and i have the applet signed. so, there shouldn't be
any restrictions anymore.
i have no ClassDefNotFoundExceptions, so i suppose, including jmf.jar works.
what else gets changed when i install jmf? there must be some restrictions that keep the vm from
determining the hosts public ip and which will be removed by the installation of jmf.
anyone had similar problems? and, perhaps, a solution to this?
thanks in advance,
honfrek
b.t.w. you can earn some duke-bucks too !

hi!
i found a very elaborate solution here:
http://www.mutong.com/fischer/java/usbcam/VideoToAppletWithNoSupport.zip
this link has been posted before,
http://onesearch.sun.com/ClickThru?qt=servlets&url=http%3A%2F%2Fforum.java.sun.com%2Fthread.jsp%3Fforum%3D28%26thread%3D515345&pathInfo=%2Fsearch%2Fdevelopers%2Findex.jsp&hitNum=45&col=devforums
this solution uses jmf only on server side for capturing, then converts the capture-stream into images, splits
the images into smaller regions and evaluates the differences of these regions to the regions of the previous image. if the difference hits a certain threshold, these regions are transmitted to the applet. but the transmission is done via tcp, which slows things down.
the splitting -code is hard for me to understand, since i'm new to java.

Signed applet works on pc but can't print on mac! security issue!

Hello
I have an applet which works beautifully on the pc under ie, firefox, chrome and safari. Essentially - it uses the batik libraries to download an svg file and then print it.
Problem is that firstly - no matter which operating system or browser the applet ALWAYS asks me if i want to give it access to the printer. The checkbox that says don't ask this again does not work except while the same applet is loaded. Subsequent loads make it reappear. So that one annoys me.
But the big issue is that under the Mac OSX my applet will not print. It claims a SocketPermission issue for the localhost port 631 connect,resolve. Of course, before you ask, yes, the jar is signed , and yes i was asked on the mac if i trust this user. It is a self signed certificate by the way.
I have no idea why the mac is not allowing my trusted app access to the printer when the other operating systems do. Is it perhaps that i am not somehow getting the AllPermission policy file read?
I have no idea where to even put the java.policy.applet that eclipse generates so i also put it into my jar file. I can't find any knowledge of that file out there or where to deploy it but i keep seeing reference to java.policy. so i copied java.policy.applet and renamed it java.policy and also included that in my jar. the upshot of doing that? Nada. With or without those policy files in my jar it makes no difference.
DocPrintJob tmpJob = tmpPrinter.createPrintJob();
HashPrintRequestAttributeSet set = new HashPrintRequestAttributeSet();
tmpJob.print(tmpDoc, set); // its this line that fails
I am new to java development (well actually about 8 years abstained from it) and this is one of those prototypes that says we either will use java or we won't. Please help, its the final hurdle. If it doesn't work on the mac then all that effort getting it to work on the PC was wasted. I also need to understand how to stop the annoying access the printer dialog before i can go live.
Cheers

If it is in the wrong format it must probably still show up though, if your mac does detect it, go to disk utilities> choose the device from the left hand side > go to the "erase" tab and change format to "Mac OS extended (Journaled) then hit "erase".
IMPRTANT! : this will erase ALL of the files on your external hard drive
If this dosent work, make sure your external hard drive's USB port is compatibe with both USB 2.0 and 3.0 and also make sure your mac USB socket isnt damaged either.
Hope this helped

Signed applet runs in Firefox but not in Internet Explorer

I've signed an applet with
keytool -genkey -validity 3650 -keyalg rsa -alias ddkey
keytool -export -alias ddkey -file ddcert.crt
jarsigner planner.jar ddkey
jarsigner -verify -verbose -certs planner.jar
but loaded from the webserver with...

<PARAM name="customer" value="mycustomer">
</APPLET>
</BODY>
</HTML>
.... the applet only works with firefox and not in Internet Explorer. Even with a new certificate, IE does not ask me whether I trust the applet or not. Only a blank screen with a red cross..
In spite of having configured "show Java console", the Java console is NOT opened in the task bar, so I cannot add further log messages....
Why do the two browsers behave differently?? How can I fix it?
Appreciate any hint :-)

When I see "it doesn't work in IE" I always have to ask: Windows 7? 64 bits system? Are you sure you are running this in the 64 bits internet explorer? The default IE is the 32 bits version, so if you don't have a 32 bits Java runtime installed applets are not going to work at all, signed or otherwise.

Problem on runtime enviorment for signed applet

I am using the Java Media Framework for video capturing .Problem which i am facing is i have to configure the client machine so i wanted to download few of the class files which will execute on the client side and then stream the video back to the server .For this i have dezigned a java applet.This applet is signed by myself without any external agency so when ever the application is executed where it was signed this application gives no problem but when a different machine access the applet the user is asked for the verification of the applet but the error is thrown stating that the class not found exception .So please guide me that while making a signed applet which all packages need to be signed and what is the procedure .Do i have to sign the jmf packages also .

I have signed applets but not with jmf. Your best bet is to put the applet in a jar and sign the jar. Most java runtimes with a self signed applet will prompt the user and ask the user if they want to grant permission. You probably have to use the java html converter to code your html to force the use of suns plugin. I am not sure if you have to sign the jmf jars or they may already be signed.

Security problem when signed applet dynamically load plugins

Hi!
I have one problem : "security problem when signed applet dynamically load plugins"
This is the scenario:
the main program [app.jar]
. contain applet and shared library (interface & implement of common class)
. it is signed and run normally on browser
. it can draw image loaded from other URL [ex] http://bp1.blogger.com/image.jpg
. the image loader is in the shared library
. dynamically load amazon.jar through URLClassLoader and reflection
the plugin [amazon.jar]
. search amazon product [ex] Harry Potter book
. draw image on applet
. use image loader from shared library, BUT CANNOT LOAD IMAGE
The question: "Why it cannot load image, because the image loader is in the shared library which has been signed and working?" I tried to sign the amazon.jar too, but it did not work.
Your reply would be very helpful. Thank you.
Sovann

hello. i have create a signed applet for A.jar. A.jar include two package B and C. the main applet class is within B.
B need some classes in C to run the applet. but i got the error that class in package c are not found.
what shall i do?

Applet works in IDE but not in browser

I have an applet that is supposed to read some data through COM port. Problem is that altough it works well in Eclipse IDE it fails without error in browser. It stops working in the point where its supposed to create instance of class that deals with reading data from COM port. I have signed applet with selfmade certificate but it didnt make any difference.

By "stops working" i mean that it never reaches next line. I put one print before and one print after the line with problem and it only prints out first line. No error is shown and try-catch also doesnt help. Is it possible that there is some sort of debug mode for applets i need to enable to see errors?
EDIT: Works now. Looks like my applet was unable to load external library when ran outside of IDE. Still dont know why i didnt get any error messages about it.

Signed Applet problems in Vista + JMF

Hi All,
I'm new to Java Applet programming. I wrote an application which works as a VoIP Client in a webpage (Using JMF). Its working very fine in allmost all Windows XP machines.
But not in Windows Vista machines. In Vista i'm getting the following error :
"No permission to capture from applet" - Since its a Signed applet. The application is digitally signed from a CA. Even though its not working in Vista (IE and Mozilla Firefox also).
I have went through the following link which says IE in Vista will run on protected mode, so Signed Applet will not have all the permission eventhough its signed for "AllPermission".
----- http://java.sun.com/javase/6/webnotes/install/system-configurations.html
And also I'm not able to create a customized jar file for JMF using JMF Customizer. (JMF Customizer is an application which creates a jar file with specified classes). While creating a jar file I'm getting particular class is not available. (In Windows XP, this class is compilled at run time).
Please let me know the following things,
a) Is there any security settings i have to make to run Signed Applet in Windows Vista ?
b) What is Java Policy file? I don't have any policy file - will it affect the application ?
c) Do I need to sign each applet (say i have 5 applets in single jar file) ?
d) In Vista how Mozilla Firefox are running (like IE7's restricted environment or XP compatiable mode) ?
Thanks in Advance,
Karthikeyan R

I have exatly the same problem but not with the class itself. I have the problem with an jar that my class calls.
I use jdk1.4.2. I think it's basicaly the same problem as "lfpgMW".
I'll also whould like an idea...
thanks

Please HELP !!! Signed Applet & Java Media Framework(JMF)

Hi,
I have written a self signed applet that is used for Recording voice running in browser:
The tag that I've given is as follows:
<OBJECT
classid = "clsid:CAFEEFAC-0014-0001-0000-ABCDEFFEDCBA"
id="recordApplet"
codebase = "http://java.sun.com/products/plugin/autodl/jinstall-1_4_1-windows-i586.cab#Version=1,4,1,0"
WIDTH = 268 HEIGHT = 27>
<PARAM NAME = CODE VALUE = "RecWindow">
<PARAM NAME = ARCHIVE VALUE = "jmf.jar,sound.jar,SignedRecWindow.jar">
<PARAM NAME = "soundtrack" VALUE="testFile.mp3">
<PARAM NAME = "type" VALUE = "application/x-java-applet;jpi-version=1.4.1">
<PARAM NAME = "scriptable" VALUE = "true">
<PARAM NAME = "MAYSCRIPT" VALUE = "true">
</OBJECT>
I've also signed jmf.jar as well as sound.jar that come in JMF 2.1 and am including it the archive. These jars are downloaded on client machine.
My code works perfectly BUT only when JMF 2.1 is installed on the clients machine else I get a RunTime Exception stating "no permission to capture from applet".
JMF FAQ states that If a user chooses to allow playing back locally stored media files or saving media files locally, he/she can do so by making use of a policy file. http://java.sun.com/products/java-media/jmf/2.1.1/faq-jmf.html#jmf2-applet-run
My requirement is that once the user has agreed to the signed applet to run then there should be no need to install JMF rather use the jmf.jar that is downloaded on client machine.
Also how can I grant the permission (permission javax.sound.sampled.AudioPermission "record";) to my applet in client computers ?
The client should not be asked to add any files (policy) by itself, all must be transparent for him.
Thanks in advance.
Vipin.

I too have been trying to get Java JMF sound recording to work via webstart. No luck so far.
I even tried playing (security.AllPermissions) with .java.policy file in the user's home directory and even modifying java.policy in the JRE/lib/security directory. No luck there too!
I also added security.AllPermissions to the javaws.policy in the JRE/jawas/javaws.policy file. Still no luck!
Any idea, anyone?

Access denied to a security provider on a signed applet

Hi,
I'm having permissions problems to work with a security provider.
The security provider is already installed at java.security. In fact, at Netbeans when debbuging the app it's working perfectly.
If I'm working the provider in an signed applet, then there are errors.
Even, I have created a .jar file and I have saved in the /ext directory, wich by default in the java.policy file has got all security permissions.
grant codeBase "file:${{java.ext.dirs}}/*" {
permission java.security.AllPermission;
Even with these granted permissions, I'm getting problems to work with the security provider that I have installed. Also, with these permissions I should be able to install the security provider.

Thank you for your information, Frank, as it clarifies part of my confusion. However, there are a couple more loose ends I'd love to address before I mark your responses as answers.
Do backup and restore privileges apply at all over a network mount created via "net use"?
The network mount requires a username and password for the destination machine. Assuming the destination machine is a Windows box with a simple CIFS share, how does this user affect our permissions and access? Do we end up effectively impersonating this
user, or is the access check still done with our sync process's run-as user?
We require that both our configured run-as user for our sync process *and* the credentials passed to the network mount be administrator users of the local system and destination system, respectively, meaning they're in of the "BUILTIN\Administrators,
S-1-5-32-544" group.
On re-syncs, the destination file will exist and since we don't have the ability to read the ACL in all cases (we're running as one user, the file is owned by another user, and we aren't specified in the ACL in any way), we aren't able to determine if the
file has changed. Is it possible to determine the owner of this file in this case? Preferably, we'd obtain the entire SDDL.
My proposed plan is to interpret access denied as a difference requiring re-sync, resulting in us taking ownership of the file, granting ourselves access, determining if there are data differences, and then re-syncing the metadata as appropriate.

Signed applet : problem signing jar files that are in build path

Hello,
I have a problem while trying to create an ftp applet.
I use org.apache.commons.net.ftp and i build path for commons-net-1.1.4.jar and then i build my classes.
When i create a jar file with my classes and after signing it, it works under eclipse but not on a web page.
I had signed commons-net-1.1.4.jar before to build the path in eclipse but commons-net-1.1.4.jar is not in my jar file.
What is the way to sign applet correctly even if some jar ressources are in eclipse build path.
Thank you

You were right!!!
I'm not sure what to write down in the formsweb.cfg (configuration file) , following the instructions on the on-line help of Developer Forms 10g , in step 9..
The step 9 says...
Because in this release the JACOB code is in an external Jar file and not incorporated into frmwebutil.jar, it needs to be downloaded. To do this, change the WebUtilArchive setting to read: webUtilArchive=/forms/webutil/frmwebutil.jar,/forms/webutil/jacob.jar
The doudt is pointed to the fact that the frmwebutil.jar isn't in the ORACLE_HOME\forms\webutil path but it is ORACLE_HOME\forms\java path.
Also , these paths referenced in webUtilArchive are physical paths in a Unix system or they are logical paths in a url?

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" />

Cannot connect to database in a signed applet

Hi i have an applet that connects to a database and does stuff. However when I move the applet to a different server i get errors. I did sign the applet but i still get
java.security.AccessControlException: access denied (java.net.SocketPermission <server> resolve)
Do I have to explicitly allow the applet to open a socket to this server, do I have to set up policy files and how exactly is this done? Please explain in detail
Thanks

First, don't use applets to connect to the database directly.

Not Signed Applets can connect to another machine?

hi, guys,
I developed a java applet, which will connect to different machine.so the local machine will grant the applet some permissions.
I did not use signed applet and want to make thing easier.
In the policy file: I add
grand {permission java.security.AllPermission };
It works.
but when I want to change to:
grand codebase "http://www.xxx.com" {permission java.security.AllPermission};
It does not work.
Can anybody help me to solve this problme?
Great thanks

grant,not grand
Also include the ipaddress, like 234.56.78.89 of www.xx.com

Why my self-signed applet could not read local disk but could write?

I used a self-signed certificate for the applet yesterday and it worked
fine at the beginning time, that is, it could write/read file to/from
local disk, and it could connect to other MDS servers. But later, a
problem happens. It could write file to local disk(I tested it and created
files to C:/ under windows) but when it try to read that file, it got a
io acessing exception. It could connect to other servers. I am puzzled
about this problem, and I wonder why I could write but could not
read. Need I deal with any policy file issue here?

hi,
i 'am doing something which is similar to the stuff ur doing .I wanted to write into file on the local disk on which the applet is running.for this i have signed the applet .do i need to make it self signed wat is difference between the self signed and signed applet .The problem which i facing is that it still gives me the security exception even if i define the policy file for that applet............Can u help me reagrding this
Thanks in advance
your great help would be apprecriated

Signed Applet able to connect to distant webservice?

Hello :)
I was wondering if an applet would be able to connect to a web service located on a distant server (Axis 1.3). I have signed the applet but it still doesn't work...
Architecture:
Signed Applet >> Axis 1.3 web service >> MySQL requests
Is it possible without editing the java.policy file on each client machine?
If the answer is no, would it be better to change my architecture by the following one ? :
Signed Applet >> Servlet >> Axis 1.3 web service >> MySQL requests
Thanks in advance for your help!
Bye

I'll try to explain a bit more what i am doing out there. It's just a test applet to gather information with forms. When the user is done filling the forms, he clic send.
The applet connects to an axis web service which connects to a MySQL databases and create the user account with the user informations filled in the applet.
Tell me if you need to know more about it. Here is the exception:
