The gLite API – PART I Giuseppe LA ROCCA INFN Catania [email protected] Master Class for Life Science, 4-6 May 2010 Singapore VOMS Java API (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 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 Links and References VOMS Proxy using Java API http://wiki.egee-see.org/index.php/SG_Generating_VOMS_Proxy_Using_Java_API http://www.euasiagrid.org/wiki/index.php/VOMS_Java_API Hands-on • Connect to the training infrastructure using the information reported in the tutorial sheet • Run the hands-on available in this web link: http://www.euasiagrid.org/wiki/index.php/VOMS_Java_API User Interface: glite-tutor.ct.infn.it Accounts: – Username: singapore02-singapore39 – Password: GridSIN02-GridSIN39 – PassPhrase: SINGAPORE $ cd ${HOME}/Api-Java-VOMS To compile and run the example: $ source VOMSProxyInitCreation.sh
