[Tpm4java-users] problem regarding javaddl & java.library.path

[Daniel P. <pin...@gm...>]

Hello all,

I have reached a confusing error while programming with tpm4java. Using
SimplePrivacyCA.creatCA() makes no problem, but as soon as I code
TssHighLevel highLevel = TssFactory.getHighLevel(); I get this error output:

Exception in thread "main" java.lang.UnsatisfiedLinkError: no javaddl in
java.library.path
    at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1698)
    at java.lang.Runtime.loadLibrary0(Runtime.java:840)
    at java.lang.System.loadLibrary(System.java:1047)
    at
de.datenzone.tpm4java.TddlJniDeviceDriver.<clinit>(TddlJniDeviceDriver.java:47)
    at de.datenzone.tpm4java.TssFactory.getLowlevel(TssFactory.java:164)
    at de.datenzone.tpm4java.TssFactory.getHighLevel(TssFactory.java:182)
    at Utils.TPMOwnership.main(TPMOwnership.java:45)


I am using linux, 2.6.28-13-generic Ubuntu with openjdk 1.6. I have already
tried System.load(path) to get the javaddl file but I get:

Exception in thread "main" java.lang.UnsatisfiedLinkError: Can't load
library: /home/daniel/tpm4java-0.9.0-src/dist/lib/javaddl


I have tried this at netbeans & eclipse with same results, I am using the VM
option (-Djava.library.path= path) as well. Anyone has an idea?

Regards,
Daniel

Hello,

I remember that when i was programming with TPM4JAVA in linux i was also using tpmemulator, a kernel module for linux that emulates a TPM. Are you using tpmemulator? You can download it from the project page 
http://developer.berlios.de/projects/tpm-emulator/

Hope it can help you.

Yes, I am using tmp emulator. After the first e-mail I checked the dev/tpm/
directory, which is inexistent. Even in case of using the emulator there
should be one there right? Probably wrong-configuration, I will try to
install it again.

As Erik said it can be a file permission problem, check it out.

Hi, /dev/tpm is read and writeable by the user who is running the code?
