If you have already built JSS, or if you are planning to use a binary release of JSS, here's how to get JSS working with your code.
- You need the JSS classes and the NSPR, NSS, and JSS shared libraries.
- NSPR and NSS Shared Libraries
JSS uses the NSPR and NSS libraries for I/O and crypto. JSS version 3.0 linked statically with NSS, so it only required NSPR. JSS versions 3.1 and later link dynamically with NSS, so they also require the NSS shared libraries.
The exact library names vary according to the convention for each platform. For example, the NSPR library is called
libnspr4.dllon Windows and
libnspr4.soon Solaris. The following table gives the core names of the libraries, omitting the platform-specific prefix and suffix.
JSS Dependencies Core Library Name Description Binary Release Location nspr4 NSPR OS abstraction layer ftp://ftp.mozilla.org/pub/mozilla.org/nspr/releases plc4 NSPR standard C library replacement functions plds4 NSPR data structure types nss3 NSS crypto, PKCS #11, and utilities ftp://ftp.mozilla.org/pub/mozilla.org/security/nss/releases ssl3 NSS SSL library smime3 NSS S/MIME functions and types nssckbi PKCS #11 module containing built-in root CA certificates. Optional. freebl_* Processor-specific optimized big-number arithmetic library. Not present on all platforms. More information... fort FORTEZZA support. Optional swft PKCS #11 module implementing FORTEZZA in software. Optional.
If you built JSS from source, you have these libraries in the
mozilla/dist/<platform>/libdirectory of your build tree. If you are downloading binaries, get them from the binary release locations in the above table. You need to select the right version of the components, based on the version of JSS you are using. Generally, it is safe to use a later version of a component than what JSS was tested with. For example, although JSS 4.2 was tested with NSS 3.11.
Component Versions JSS Version Component Tested Version JSS 4.2 NSPR 4.6.4 NSS 3.11.4 JSS 3.4 NSPR 4.2.2 NSS 3.7.3 JSS 3.3 NSPR 4.2.2 NSS 3.6.1 or 3.7 JSS 3.2 NSPR 4.2 or 4.1.2 NSS 3.4.2 JSS 3.1.1 NSPR 4.1.2 NSS 3.3.1 JSS 3.1 NSPR 4.1.2 NSS 3.3 JSS 3.0 NSPR 3.5.1
- JSS Shared Library
The JSS shared library is
libjss4.so(Unix). If you built JSS from source, it is in
mozilla/dist/<platform>/lib. If you are downloading binaries, get it from ftp://ftp.mozilla.org/pub/mozilla.org/security/jss/releases/.
- JSS classes
If you built JSS from source, the compiled JSS classes are in
mozilla/dist/classes[_dbg]. You can put this directory in your classpath to run applications locally; or, you can package the class files into a JAR file for easier distribution:
cd mozilla/dist/classes[_dbg] zip -r ../jss42.jar .
If you are downloading binaries, get jss42.jar from ftp://ftp.mozilla.org/pub/mozilla.org/security/jss/releases/.
You need to set some environment variables before building and running Java applications with JSS.
Include the path containing the JSS classes you built, or the path to
jss42.jar. (The path to
jss34.jarends with the string "/jss42.jar". It is not just the directory that contains
- Include the path to the NSPR, NSS, and JSS shared libraries.
Before calling any JSS methods, you must initialize JSS by calling one of the
CryptoManager.initialize methods. See the javadoc for more details.
