Simplest way to sign Java applets

is there a way that i could sign applets without using the command line? its kinda in efficient if i may say.
thanks in advance.

Maybe an IDE will be able to do it?
Or you could create a build script (ant is good), so building your applet (including signing it) becomes
ant clean; ant
You could event expand it to deploy.
ant deploy

Simplest way to sign a JAR?

I made an applet using Eclipse that pulls information from a website while running. Apparently this needs to be signed before it works online -- what is the quickest, easiest way to sign it?
I'm one of the few people who are going to be using this applet, and I have basically no knowledge about JARs. I read the tutorial here but it didn't help me at all, as I don't have a "keystore" on my computer and I don't even know where to type any of that ("that" being jarsigner -keystore mykeys -storepass abc123 -keypass mypass app.jar johndoe).
I tried to run the unsigned JAR using Firefox (+<applet code="MU.class" archive="MU.jar" width=300 height=400>+). The applet didn't even initiate, it simply turned into a white box saying Error. Click for details -- clicking it brought up a Java Console starting with this line: java.security.AccessControlException: access denied (java.net.SocketPermission www.forsaken-mu.com:80 connect,resolve).

Did I click the wrong link, or is it just out of date?Those are pointing to the 1.2 JavaDocs. I have always wished Sun would establish an URL for the current API and tool documentation. As the new JRE major versions are released for public use, the docs should change accordingly.
Try instead [http://java.sun.com/javase/6/docs/technotes/tools/windows/keytool.html].
Out of curiosity. How did you get that URL?
As to your more general question of "Simplest way to sign a JAR?". I would answer that "Load a project (that signs code) with a build.xml into your IDE and call the main task."
But there are some caveats to that advice.
1) There are very few people on these forums willing to help with IDEs, so it is up to you to figure out how to import/build the ant based project, or take it to a forum for the IDE.
2) Understanding what the build file is doing, depends on understanding the underlying tools it calls. Most of those tools come directly from the JDK.
Having said that, I do have some open source projects that digitally sign code. For example the [demo. of the JNLP API file service|http://pscode.org/jws/api.html#fs] with the source files available in [http://pscode.org/jws/filetest.zip]. Maybe you can get a head start by looking that over (and building it, and changing it etc.).

Using external libraries over signed Java applet: InvocationTargetException when running locally with 7u51

We have a signed Java applet that uses external libraries, specifically the OpenOffice application libraries.
We have a problem running Java applet with 7u51 of "InvocationTargetException" when use these libraries OpenOffice, that is not signed; regardless of the browser used (Mozilla Firefox, Explorer, Chrome).
Please, as you could solve this problem? This problem can not arose with 7u40 and earlier..

START OF DOC
How To Sign a Java Applet
The purpose of this document is to document the steps required to sign and use an
applet using a self-signed cert or CA authorized in the JDK 1.3 plugin.
The original 9 steps of this process were posted by user irene67 on suns message forum:
http://forums.java.sun.com/thread.jsp?forum=63&thread=132769
-----begin irene67's original message -----
These steps describe the creation of a self-signed applet. This is useful for testing purposes. For use of public reachable applets, there will be needed a "real" certificate issued by an authority like VeriSign or Thawte. (See step 10 - no user will import and trust a self-signed applet from an unkown developer).
The applet needs to run in the plugin, as only the plugin is platform- and browser-independent. And without this indepence, it makes no sense to use java...
1. Create your code for the applet as usual.
It is not necessary to set any permissions or use security managers in
the code.
2. Install JDK 1.3
Path for use of the following commands: [jdk 1.3 path]\bin\
(commands are keytool, jar, jarsigner)
Password for the keystore is any password. Only Sun knows why...
perhaps ;-)
3. Generate key: keytool -genkey -keyalg rsa -alias tstkey
Enter keystore password: *******
What is your first and last name?
[Unknown]: Your Name
What is the name of your organizational unit?
[Unknown]: YourUnit
What is the name of your organization?
[Unknown]: YourOrg
What is the name of your City or Locality?
[Unknown]: YourCity
What is the name of your State or Province?
[Unknown]: YS
What is the two-letter country code for this unit?
[Unknown]: US
Is CN=Your Name, OU=YourUnit, O=YourOrg, L=YourCity, ST=YS, C=US
correct?
[no]: yes
(wait...)
Enter key password for tstkey
(RETURN if same as keystore password):
(press [enter])
4. Export key: keytool -export -alias tstkey -file tstcert.crt
Enter keystore password: *******
Certificate stored in file tstcert.crt
5. Create JAR: jar cvf tst.jar tst.class
Add all classes used in your project by typing the classnames in the
same line.
added manifest
adding: tst.class(in = 849) (out= 536)(deflated 36%)
6. Verify JAR: jar tvf tst.jar

849 Thu Jul 27 12:49:04 GMT+02:00 2000 tst.class
7. Sign JAR: jarsigner tst.jar tstkey
Enter Passphrase for keystore: *******

9. Create HTML-File for use of the Applet by the Sun Plugin 1.3
(recommended to use HTML Converter Version 1.3)
10. (Omitted See Below)
-----end irene67's original message -----
To make the plug-in work for any browser you have two options with the JDK 1.3 plugin.
1) Is to export a cert request using the key tool and send it to a CA verification source like verisign.
When the reponse comes back, import it into the keystore overwriting the original cert for the generated key.
To export request:
keytool -certreg -alias tstkey -file tstcert.req
To import response:
keytool -import -trustcacerts -alias tstkey -file careply.crt
An applet signed with a cert that has been verified by a CA source will automatically be recognized by the plugin.
2) For development or otherwise, you may want to just use your self-signed certificate.
In that case, the JDK 1.3 plugin will recognize all certs that have a root cert located in the JDK 1.3 cacerts keystore.
This means you can import your test certificate into this keystore and have the plugin recognize your jars when you sign them.
To import self-signed certificate into the cacerts keystore, change directory to where the JDK plugin key store is located.
For JDK 1.3.0_02: C:\Program Files\JavaSoft\JRE\1.3.0_02\lib\security
For JDK 1.3.1: C:\Program Files\JavaSoft\JRE\1.3.1\lib\security
Import your self-signed cert into the cacerts keystore:
keytool -import -keystore cacerts -storepass changeit -file tstcert.crt
(the password is literally 'changeit')
Now, regardless of which method you use, the applet should be recognized as coming from a signed jar. The user can choose to activate it if he / she chooses. If your applet uses classes from multiple jars, for example Apache's Xerce's parser, you will need to sign those jars as well to allow them to execute in the client's brower. Otherwise, only the classes coming from the signed jar will work with the java.security.AllPermission setting and all other classes from unsigned jars will run in the sandbox.
NOTE: Unless otherwise specified by the -keystore command in all keytool and jarsigner operations, the keystore file used is named '.keystore' in the user's home directory.
The first time any keystore is accessed (including the default) it will be created and secured with the first password given by the user. There is no way to figure out the password if you forget it, but you can delete the default file and recreate it if necessary. For most operations, using the -keystore command is safer to keep from cluttering or messing up your default keystore.

Signed java applet is very slow with 1.4.2_06

We have an application which has a signed jar applets was working fine with Java Plug-in (JPI) version 1.4.1_02.
Due to customer requirement they want to run the same applet with JPI version 1.4.2_06, After JPI upgrade the applet is running slow.
I am not sure what sun has changed the security settings in 1.4.2_06. So, Can some one give there thoughts on why would it run slow because of JPI changes.
Thanks in advance.
Aj

Hi,
It is nothing to do with Signed applet.
If URL Connection 's setDefaultCacheUses is set to false then this is causing to run the Applet slow. As it require to download complete jar(if any) everytime.
From 1.4.1_02 (CachedJarURLConnection.class in jaws.jar):
public void connect()
throws IOException
if(!connected)
jarFile = JarCache.get(jarFileURL);
if(jarFile != null)
{�.
From 1.4.2_06 (CachedJarURLConnection.class in plugin.jar):
public void connect()
throws IOException
if(!connected)
if(getUseCaches())
jarFile = JarCache.get(jarFileURL);
if(jarFile != null)

Signed Java Applet

I have written an applet with Netbeans. When I click on Clean and Build then Netbean create a jar file "Test.jar" and also another folder called lib in the same directory. I've signed the Test.jar. Basically this applet upload files to server with FTP. So when Applet loads into browser then I am able to select files but when I click on upload then it stops. So my question is:
1. Have I also need to sign all dependent jar files?
2. My directory structure is as follow:
C:\AppletPage.html C:\Test.jar C:\lib
and code in html file is as follow
<applet code="UploadGUI.class"
archive="test.jar"
width=400 height=400></applet>Please advice me where am I wrong?
Thanks in Advance

I see no reason why you want to make this applet for the msjvm, here is how you do it with the sun sdk:
Signing applets:
http://forum.java.sun.com/thread.jsp?forum=63&thread=524815
second post and last post for the java class file
http://forum.java.sun.com/thread.jsp?forum=63&thread=409341
4th post explaining how to set up your own policy with your own keystore
(my copy and paste fingers are really getting tired now, copyd and pasted this
for about a 100 times now)
Notice some differences in the html code of the examples (they don't use the applet tag)
If you're aiming for the msjvm because you don't want any support form MS in
the near future and want to delever a legacy unsupported unmaintainable applet
than I have to ask you how you compiled the applet. If you used the SUN sdk
then are you aware that the msjvm cannot handle java version higher than 1.1?
So you have to compile it like this: javac -source 1.3 -target 1.1 ....
Your html file seems to be missng the cabbase value so how do you expect
IE to find the cab file?

Signed JAVA applet still not connecting.

I have a signed applet that works in my development environment, but as soon as I run it from my website, I get this:
basic: Referencing classloader: sun.plugin.ClassLoaderInfo@1754ad2, refcount=1
basic: Added progress listener: sun.plugin.util.GrayBoxPainter@a7c45e
basic: Loading applet ...
basic: Initializing applet ...
basic: Starting applet ...
basic: completed perf rollup
network: Connecting socket://XXX.XX.X.XXX:XXXX with proxy=DIRECT
And that's it, it stops. It never loads the UI, or anything.
I believe the signing worked. I accepted the security certificate when it came up. I'm not getting any other errors (Like a security error).
any help would be appreciated.
I realize this isn't a lot of information, but It works fine in the IDE, so I don't think it's the code. I have stack traces in every try/catch, so I should see any exceptions. Also, this is being served by the same server as the web-page. It didn't work before I signed it, so I thought that would fix it.
The only error like this that I find on the forums is an unsigned applet not working after it's moved to the server.
Anyone have any ideas?

Make sure that the remote socket you are connecting to, i'm assuming probably your home computer? has the port(s) at your (local) router forwarding to your computer,or whichever computer is listening for the connection.

Creating signed Java applet for Netscape 4x

I have created a signed jar with SuperUser privileges under Netscape.
public void init() {
try {
if( Class.forName("netscape.security.PrivilegeManager") != null ) {
netscape.security.PrivilegeManager.enablePrivilege("SuperUser");
} catch( ClassNotFoundException cnfe ) {
cnfe.printStackTrace();
With this I am getting following error without any dailog prompting to grant permission.
netscape.security.ForbiddenTargetException: User didn't grant the SuperUser privilege.
Please help.
Thanks
Satish

Then it's likely Netscape 4.x doesn't recognize the jar as being signed. How did you sign the jar?
Why didn't you ask this in the more appropriate Signed Applets forum?

Java applet and vertical scroll bar

Hi,
We are upgrading from SRM 3.0 to 5.0 and are encountering these 2 issues:
1- When clicking on approval preview users get a Java pop up box titled "request authentication", the warning message is: Identification Required. Please select certificate to be used for authentication." when the click okay it disappears and approval preview is displayed. No configuration is maintained for signed java applet.
2- in shop create on the web, everytime the page gets refreshed from entering data or clicking on an icon, it displays back in sections starting with the top of the page (default settings for items) and it may take up to 20 seconds for the whole page to finally get displayed.
If anyone has encountered and was able resolve these issues, please let me know.
(SRM 550 SAPKIBKT10)
Thank you,
Richard

Not sure if this issue is resolved, but the 1st question is something which is related to the IT Network/PC division folks. The certificate is termed "unsafe" or "not trusted" by your network, this is why you get the popup everytime. Inform the network division of your company which is responsible for the maintenance of servers/workstations to add this certificate into the "trusted certificate" list of their servers. Even your basis team should be able to guide you.

Java 1.5.09/10 Java Applet on Vista - starts but never downloads files

We are attempting to test a java 1.5.07 compiled and signed Java applet with Windows Vista (from MSDN).
Logged in as an administrator on the client PC, we installed the 1.5.09 and the 1.5.10 JRE on the client.
We then changed the html of the applet page to specifiy the new plugin version so it matched the JRE installed on the client.
When we start up IE7, point to our HTML applet page, and attempt to download (cache) our applet, the default Java plugin graphic with the progress bar onthe bottom shows up, but no progress is ever made.
Taking a look at the Java console with full debugging turned on, we don't see any activity. When I dumped the classloader list, it only shows the codebase string, but no classes are actually loaded.
I thought that maybe a popup window (asking to verify the certificate) might have popped up and was hidden by another window, but that's not the case. It never appears.
Does anyone have any thoughts or suggestions? I can certainly attempt to capture more debug if someone can point me in the right direction!
Thanks!
-Matt

Ok, some more info - and this gets interesting!
The server is located in a DMZ here at work. (We have offshore teams in russia who are developing and testing code)
It seems to be an issue with the internal firewall/DMZ here at work.
We moved the codebase to a machine that is locally located (not in a DMZ) and presto, the applet begins to download.
When I find out more information, I'll post in case anyone else comes across a similar concern/issue. It may be the firewall/router vendor?!?

Firefox 23 is blocking local Java applets

My company's signed Java applet runs fine from online websites. The applet is designed also to be used from CDs and other local file systems. However it does not now run at all when running locally, eg from a URL like this: file:///D|/fiscd/search2.htm
The applet tag looks like this:
<APPLET CODE=fisCD NAME=fisCD WIDTH=500 HEIGHT=300 ARCHIVE="fiscd.jar" MAYSCRIPT>
</APPLET>
I think this started in Firefox 23 and is possibly related to this fix:
http://www.mozilla.org/security/announce/2013/mfsa2013-75.html
Other users are also seeing this problem.
Do you have a fix for this problem?
Can you check that local signed Java applets can run OK please?
Any other suggestions?
