I tried to use jBPM by the tutorial on http://docs.jboss.org/jbpm/v5.2/userguide/ch03.html#d0e402 http://docs.jboss.org/jbpm/v5.2/userguide/ch03.html#d0e402. I can install it by tipping 'ant install.demo'. But by tipping 'ant start.demo' an error occured. I don't know why. Can someone help me? The error message is: C:\jBPM\jbpm-installer>ant start.demo Buildfile: C:\jBPM\jbpm-installer\build.xml download.h2.check:      [echo] Checking h2 download ... download.h2: start.h2: start.jboss: check.jboss.version: start.jboss5: check.jboss.version: start.jboss7: start.eclipse: start.human.task:     [javac] C:\jBPM\jbpm-installer\build.xml:664: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds     [javac] Compiling 1 source file to C:\jBPM\jbpm-installer\task-service\target     [javac] error: error reading C:\ant\apache-ant-1.8.2\lib\jai-core-1.1.3.jar; error in opening zip file     [javac] 1 error BUILD FAILED C:\jBPM\jbpm-installer\build.xml:664: Compile failed; see the compiler error out put for details. I think my JAVA_HOME variable is right, because 'ant install.demo' was successful. The file jai-core-1.1.3.jar exists in C:\ant\apache-ant-1.8.2\lib. So I realy helpless. I hope someone can help me.
