Hands-on
Installing the Java API
•
The needed libraries to interact with the VOMS server
are:
–
–
–
–
–
–
–
–
–
–
–
–
glite-security-voms.jar
bcprov.jar
log4j.jar
cog-jglobus.jar
common-lang.jar
common-cli.jar
glite-security-utils.jar
commons-logging-api.jar
puretls.jar
cryptix.jar
cryptix32.jar
cryptix-asn1.jar
W A R N I N G
Make sure all the listed
jar(s) are included in
your CLASSPATH
environment variable !!
Installing the Java API
NOTE: There are conflicts with glite-security-voms.jar when
using glite-security-utils.jar which should be located after
glite-security-voms.jar in the CLASSPATH environment
variable. The conflicting classes that are the ones contained in
the both packages are of older version.
These libraries can be downloaded from here
Configure System properties
Before we begin with the proxy generation, we need to specify the
following System properties. If omitted the default values are
used.
Configure VOMS Server settings
• Configure the VOMS Server settings using the Java class
org.glite.security.voms.contact.VOMSServerInfo
Instantiate the class
• The main Java class of this API is:
org.glite.security.voms.contact.VOMSProxyInit
• A client object can be created providing to the constructor a
password for the opening of the user certificate:
public static VOMSProxyInit instance(String privateKeyPassword)
Parameters and Methods /1
• After the generation of the VOMSProxyInit object class, we need
to specify additional parameters for the proxy generation.
Parameters and Methods /2
Parameters and Methods /3
