¿Cómo se inscribe un MIDlet de Java?

Question

Una simple pregunta con una respuesta bastante complicado:

¿Cómo se inscribe un MIDlet de Java para que pueda cargarlo en un teléfono móvil con menos indicaciones de seguridad?

Answer 1

de software Consigue requerida

    
1. SDK Java ( JDK) de Sun (ya debe tener esto)
    
2. Java Wireless Toolkit (WTK) también de Sun
    
3. Opcionalmente conseguir e instalar Ant y antena que le permite automatizar la compilación (recomiendo encarecidamente estos)

Importar un certificado existente (si lo tiene)

    
1. Si usted ha comprado un certificado de Verisign (u otro proveedor) que necesita para importar el certificado en el almacén de claves de J2SE.
    
2. Intente utilizar el siguiente comando keytool -import -alias {myalias} -file {mycertificate} (no he podido probar esto, ya que no tengo un certificado adecuado)
    
3. Ejecutar keytool -list para ver su nuevo certificado
    
4. A continuación, debe exportar el certificado para que pueda importar a su teléfono
    
5. Ejecutar keytool -export -alias {myalias} -file mycertificate.crt
    
6. Importar el certificado en el teléfono (ver más abajo para más detalles)

Crear e importar un nuevo (prueba) Certificado

    
1. Es necesario utilizar herramienta de claves ( del JDK)
    
2. I utiliza el siguiente comando keytool -genkey -alias {myalias} -keyalg RSA -validity 365
    
3. Esto le pedirá una contraseña de almacén de claves, introduzca la contraseña del almacén de claves (si tiene un almacén de claves existente) o el que desea utilizar si no tiene uno todavía
    
4. Rellene todos los avisos sobre nombre de ubicación / empresa, etc.
    
5. Ejecutar keytool -list para ver su nuevo certificado
    
6. A continuación, debe exportar el certificado para que pueda importar a su teléfono
    
7. Ejecutar keytool -export -alias {myalias} -file mycertificate.crt
    
8. Importar el certificado en el teléfono (ver más abajo para más detalles)

C:\j2sdk1.4.2_08\bin>keytool -genkey -alias company -keyalg RSA -validity 365
Enter keystore password: password
What is your first and last name? [Unknown]: My Name
What is the name of your organizational unit? [Unknown]: company
What is the name of your organization? [Unknown]: company
What is the name of your City or Locality? [Unknown]: location
What is the name of your State or Province? [Unknown]: location2
What is the two-letter country code for this unit? [Unknown]: GB
Is CN=My Name, OU=company, O=company, L=location, ST=location2, C=GB correct? [no]: yes
Enter key password for (RETURN if same as keystore password):

Construir y empaquetar la aplicación

    
1. javac para construir su MIDlet prestando especial atención a la ruta de clases y las opciones bootclasspath (de lo contrario se producirá un error verificación previa). Asimismo, establecer objetivo a 1,1 y la fuente a 1,3
    
2. Generar el archivo JAD los atributos críticos de la JAD son  MIDlet-Jar-URL, MIDlet-Jar-Size, MIDlet-Permisos que también se incluye MIDlet-Icon, MicroEdition-configuración, MicroEdition-Perfil, MIDlet-Name, MIDlet-Push-1, MIDlet-Icon, MIDlet-Descripción y MIDlet- versión
    
3. Generar el archivo MANIFEST.MF en función de su JAD, debe quitar MIDlet-Jar-Size y MIDlet-Jar-URL
4. Both these tasks can be completed using the wtkJad Antenna task
5. Package and preverify the app using the wtkPackage Antenna Task you must set the classpath and bootclasspath properties correctly otherwise Preverification will fail

Sign the application

1. Sign the Application using jarsigner
2. Run jarsigner -keystore {mykeystore} -storepass (mypassword} {myjar} {myalias}
3. Now you have a signed jar you need to update the MIDlet-Jar-Size in your JAD
4. Now add the certificate to the JAD using JadTool.jar from the WTK
5. Run java -jar JadTool.jar -addcert -alias {myalias} -storepass {mypassword} -keystore {mykeystore} -inputjad {myinputjad} -outputjad {myoutputjad}
6. Now add the signature to the JAD again using JadTool.jar
7. Run java -jar JadTool.jar -addjarsig -alias {myalias} -jarfile {myjar} -storepass {mypassword} -keypass {mypassword} -keystore {mykeystore} -inputjad {myinputjad} -outputjad {myoutputjad}

Deployment

1. Deploy this to a web server with the MIME types set correctly and download it to your phone and it will be a trusted 3rd party application
2. You can also deploy applications to phones by sending the JAR & JAD to the phone over Bluetooth or Infrared or a cable depending on your phones features. On Nokia phones the files appear in your SMS Inbox

Installing the Certificate on the phone

1. Import the certificate into your phone, in Windows XP SP2 I could do this by right clicking the file and selecting "Send to Bluetooth Device", you should be able to send files by cable or Infra Red (IR) too. NB: I haven't found anyway of importing a certificate on a Series 40 phone
2. Once the certificate is installed it needs to be authorised for "Application Installation". On my phone (Nokia 6680) this is under Tools->Settings->Certificate Management->Trust Settings, I turned on everything but I think "Application Installation" is all you need

Common Problems

1. Application not installed using the JAD: The application is only trusted if it is installed using the JAD, the application will still install from the jar but it won't be trusted.
2. Application trust settings not set: Once your application is installed you need to specify how much trust to give it (it doesn't get all permissions by default). On a Nokia Series 60 phone these are found under the App. Manager.
3. Root certificate missing from phone: The Java Verified certificate and/or Verisign certificates are missing from some phones check under Tools->Settings->Certificate Management for the relevant certificate
4. Authorization Failed: - There are a whole host of possible reasons behind this here are the ones I've come across
   1. Certificate missing from phone, double check your certificate is installed and has been marked as trusted for application installs in Certificate Management
   2. Reboot: Uninstall the application completely then reboot your phone try taking the battery and SIM out too, often things get themselves in a twist, especially if you've been re-installing a lot without uninstalling first
   3. JAD/JAR mismatch: Double check the application size in the JAD, remember it's the number of bytes that is important NOT the size on disk
   4. Browser cache: If you're installing over the air make sure you clear your browser cache before installing
   5. I've heard but not verified that line breaks in the MIDlet-Permissions can cause problems but it seems ok to me on Nokia 6680/6630/6230i (could be firmware dependent?)
   6. The MIDlet-Permissions attribute is the cause of a lot of problems (especially since the documentation is often wrong/missing or different depending on the phone), try leaving it out first and add permissions in one at a time. Some phones will complain about permissions they don't support, some will ignore them
5. There is a bug in some early Nokia 6600 firmwares that stop the install of trusted MIDlets
6. Certificate not valid yet: If you generated the certificate yourself it may have a start validity date of tomorrow, also if your PC and phone dates are different you may be outside the period of validity of the certificate
7. No certificate management on Series 40 phones, you can install a signed application but behavior is strange with self signed certificates
8. JadTool problems: I haven't experienced any of these issues but lots of other people have
   1. "I have issues if I try to use the jadtool manually. I have a certificate chain and can't seem to get the second certificate added to the JAD file using any WTK jadtool. The interesting part however is that I can successfully sign the midlet using any of the same WTK GUI interfaces - they add the second certificate correctly. My steps:
      1. Use 1.4.2_06 jarsigner.exe to sign jar
      2. Use WTK (2.2 or 2.3 beta) jadtool to addcert with certnum 1
      3. If I call jadtool to addcert with certnum 2 the same certificate is inserted as cert 1-2 I'm assuming I am doing something incorrectly since the WTK gui seems to be working just fine"
   2. "I received a post on the KVM news group on the topic that states there is a bug in the jadtool and the author claims to have filed a bug report and posted a patch: http://archives.java.sun.com/cgi-bin/wa?A2=ind0508&L=kvm-interest&F=&S=&P=9858 One interesting note that was also posted was that the cert JAD params are static so once you get them from the WTK correctly you can put them statically in the ant script."
   3. "I am trying to sign a MIdlet for Nokia 6620 device. I am using a Verisign Code Signing certificate that actually contains two certificates (User and Intermediate CA). I am using the WTK 2.2 signing tool. Do you know if this tool support two certificates when signing ? The signature is added to the JAD file with two certificates but I have been getting security error when installing. I have checked on the device and there are different root certificates installed for Verisign but it still fails !
   4. "If you want, you can download the sprintpcs developer kit as it supports dual certs (http://developer.sprintpcs.com). However, I never got that cert to work on the Nokia (6620/cingular) phone, although it does work on sprint phones (with developer root enabled). Ultimately, I only got things to work by creating the cert as described in this blog and installing that on the phone. Bizarrely, even though the root cert for my versign-signed cert *was* on the 6620 phone, it still would never install my MIDlet as you would think it should."
9. Old phones (6230/i, 6682) don't support x509 certificates, WPKI has been suggested as a possible solution but I haven't investigated this
10. Socket connections can be problematic (http://discussion.forum.nokia.com/forum/showthread.php?t=68306 ) possibly due to the WAP infrastructure and the services provided by an operator. HTTP is a much safer protocol to use
11. "Go online and check application validity": Yes/No. If I click on yes button the phone I get the following error: "Certificate revoked for this application" and the installation fails. To rectify this go to Tools -> Manager -> Menu -> Settings -> Online Certif Check [ On / Off / Required] There is also a Default address setting. If the online control setting is required, the check will fail, if there is no default address. see http://discussion.forum.nokia.com/forum/showthread.php?t=71071

Trust Domains

1. There are 4 different trust domains in MIDP2 (manufacturer, operator, trusted third party, and untrusted). Trusted Third Party is the only one of any use to us really.It gives the following options on my Nokia 6680 (Vodafone UK):
Network Access: Not Allowed, Ask every time, Ask first time Messaging: Not Allowed, Ask every time App Auto-Start: Not Allowed, Ask every time, Ask first time Connectivity: Not Allowed, Ask every time, Ask first time, Always allowed Multimedia: Not Allowed, Ask every time, Ask first time Read User Data: Not Allowed, Ask every time, Ask first time, Always allowed Edit User Data: Not Allowed, Ask every time, Ask first time, Always allowed
2. These settings are defined by the operator and the phone manufacturer and therefore vary between phone, manufacturer and operator.

Unresolved Problems

1. I managed to sign the JAD with this format using J2ME WTK utilities, but when trying to install it on the device I get a message "Application authentication failed 909".

Answer 2

Paso 1:     Crear solicitud de RSE que puedan ser planteadas por

1) Creating keystore and using that generate CSR file.
2) Perform steps given by certificate authority and download CSR and private key files.

Paso 2:     Dar su información a la autoridad de certificación para su verificación.

Paso 3:     Se le proporcionará un certificado de firma de código.

Paso 4:     Es necesario que la carga certificado intermedio hacia abajo junto con el certificado raíz.

Paso 5:     Ahora va a tener your_domain_name.crt, IntCertCA.crt, TrustedRoot.crt

Now you need to create a chained certificate by combining all above certificates.

1) Open a text editor (such as wordpad) and paste the entire body of each certificate into one text file in the following order:

    The Primary Certificate - your_domain_name.crt
    The Intermediate Certificate - IntCertCA.crt
    The Root Certificate - TrustedRoot.crt
    Make sure to include the beginning and end tags on each certificate. The result should look like this:

    -----BEGIN CERTIFICATE----- 
    (Your Primary SSL certificate: your_domain_name.crt) 
    -----END CERTIFICATE----- 
    -----BEGIN CERTIFICATE----- 
    (Your Intermediate certificate: IntCertCA.crt) 
    -----END CERTIFICATE----- 
    -----BEGIN CERTIFICATE----- 
    (Your Root certificate: TrustedRoot.crt) 
    -----END CERTIFICATE-----

    Save the combined file as your_domain_name.pem. The .pem file is now ready to use.

Paso 6:         clave privada importación en su your_domain_name.pem

    openssl pkcs12 -export -in your_domain_name.pem -inkey your_private_key.key -out output_file_name.p12 -name your_alias


    NOTE: PLEASE REMOVE \ FROM FOLLOWING COMMANDS AND EXECUTE ( \ IS BASICALLY COMMAND CONTINUETY )

Paso 7:         Crear almacén de claves de output_file_name.p12

    keytool -importkeystore \
     -deststorepass changeit -destkeypass changeit -destkeystore your_domain_keystore.ks \
     -srckeystore output_file_name.p12 -srcstoretype PKCS12 -srcstorepass your_store_password \
     -alias your_alias

Paso 8:         NOTA:. Por favor, tome de seguridad del archivo JAD antes de activar siguientes comandos

    Add your certificates to your your_midlet_name.jad file.

    java -jar JadTool.jar -addcert -alias your_alias \
    -storepass your_store_password \
    -keystore your_domain_keystore.ks \
    -inputjad your_midlet_name.jad -outputjad your_midlet_name.jad      

Paso 9:         NOTA:. Por favor, tome de seguridad del archivo JAD antes de activar siguientes comandos

    Sign your midlet, also use your_midlet_name.jad file generated from Step8.

    java -jar JadTool.jar -addjarsig \
    -alias your_store_password \
    -storepass your_store_password \
    -keypass your_store_password \
    -keystore your_domain_keystore.ks \
    -inputjad your_midlet_name.jad -outputjad your_midlet_name.jad
