1. The gLite API – PART I Giuseppe LA ROCCA INFN Catania giuseppe.larocca@ct.infn.it Master Class for Life Science, 4-6 May 2010 Singapore

2. VOMS J a v a A P I (ver 1.8.12-1) Software Requirements Java Classes org.glite.security.voms.contact.VOMSServerInfo org.glite.security.voms.contact.VOMSProxyInit org.glite.security.voms.contact.VOMSRequestOptions t Hands-on

3. 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 !!

4. 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 herehere

5. Before we begin with the proxy generation, we need to specify the following System properties. If omitted the default values are used. Configure System properties

6. Configure the VOMS Server settings using the Java class org.glite.security.voms.contact.VOMSServerInfo Configure VOMS Server settings

7. 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) Instantiate the class

8. Parameters and Methods /1 After the generation of the VOMSProxyInit object class, we need to specify additional parameters for the proxy generation.

9. Parameters and Methods /2

10. Parameters and Methods /3
