jarsigner

I have developed a blackberry application which I have loaded in the BB device. But as we know, without signing the application with RIM we can't run the application on the device. Is there any way which I can create the trial version of my application for some days and run it in the device for testing purposes. I have heard about the "keytool" and "jarsigner" tools. Can this tools help me to run my application in device without signing the application? If yes, please give me the steps regarding how it can be done. M. S. The steps to sign a java archive (.jar file). First create the public key

Hi I am new with java modules so this might be a dumb question. I was trying to sign my jar file with keystore and got the following error. user@Ubuntu:libs(master)$ jarsigner -keystore keyStoreFileName Test.jar alias Enter Passphrase for keystore: jarsigner: unable to sign jar: java.util.zip.ZipException: duplicate entry: module-info.class I couldn't find any documentation of how to avoid this. So I did jar -tf to check the content of the jar and yes, it does have multiple module-info.class files Is there any option to combine them? and how? my module-info.java contains the following. module

I am getting the error: [signjar] jarsigner: attempt to rename C:\workspace\line_editor\lib\icon.jar to C:\workspace\line_editor\lib\icon.jar.orig failed when attempting to self sign a set of jars with ant inside Eclipse.

I get the following error on a self-signed jar: jar verified. Warning: This jar contains entries whose certificate chain is not validated. Re-run with the -verbose and -certs options for more details. I signed the jar like this: "C:\Program Files\Java\jdk1.7.0\bin\jarsigner" -keystore myKeyStore myJar.jar myAlias My jar has 2 entry points: One for java web start, and one for an applet. If I run the jar in a java web start way, it has no incidence. But if I run the jar as an applet. I get a strong security warning at some point when I try to access a bitmap resource embeded in the jar. Using

I'm automating some things that involve the android keytool and jarsigner. The tool takes a keystore, the password for the keystore, the alias name, and the password for the alias / key, and I'm trying to find a way to explicitly check to see if the supplied password for the alias / key is correct. Any ideas? Also, I need to check it without a jar file to sign - getting that file in my context is lengthy, so I want to abort sooner rather than later. You can also check if the password is correct without attempting to change the password. I did it by listing the properties of the keystore with

I want to use verify an APK from Java code using JarSigner. I am writing an app that programatically installs APKs (much like Google Play) and before installing it checks for the following: Verify the signature of the .SF file itself.Verify the digest listed in each entry in the .SF file with each corresponding section in the manifest. Verify the digest listed in each entry in the .SF file with each corresponding section in the manifest. Read each file in the JAR file that has an entry in the .SF file. While reading, compute the file's digest, and then compare the result with the digest for
