You have a generation problem in the Talend Administration Center (TAC) even if your Job runs successfully in the Studio.
Resolution
Try to export the Job as a Jobscript from the Studio to make sure the export is working.
If the Job has custom components:
Check if those custom components are specified in the TAC under CommandLine, on the Configuration page.
Check that all libraries needed are in the /lib/java directory. If they are not, add the missing ones.
Regenerate the task.
Cause
Your Job runs well in the Studio, but you cannot generate it in the Talend Administration Center. It is getting the following Java error:
java.lang.NullPointerException at org.talend.designer.runprocess.java.JavaProcessorUtilities.sortClasspath(JavaProcessorUtilities) at org.talend.designer.runprocess.java.JavaProcessorUtilities.computeLibrariesPath(JavaProcessorUtilities...) at org.talend.designer.runprocess.DefaultRunProcessService.updateLibraries(DefaultRunProcessService...) at org.talend.designer.runprocess.RunProcessService.updateLibraries(RunProcessService...) at org.talend.designer.runprocess.ProcessorUtilities.generateBuildInfo(ProcessorUtilities...) at org.talend.designer.runprocess.ProcessorUtilities.generateCode(ProcessorUtilities...) at org.talend.designer.runprocess.ProcessorUtilities.generateCode(ProcessorUtilities...) at org.talend.designer.runprocess.ProcessorUtilities.generateCode(ProcessorUtilities..) at org.talend.repository.ui.wizards.exportjob.scriptsmanager.JobScriptsManager.generateJobFiles(JobScriptsManager...) at org.talend.repository.ui.wizards.exportjob.scriptsmanager.JobScriptsManager.generateJobFiles(JobScriptsManager...) at org.talend.repository.ui.wizards.exportjob.scriptsmanager.JobJavaScriptsManager.getExportResources(JobJavaScriptsManager...) at org.talend.commandline.util.JobHandler.export(JobHandler...) at org.talend.commandline.command.CommandProcessor.doExportJob(CommandProcessor...) at org.talend.commandline.command.CommandProcessor.exportJob(CommandProcessor...) at org.talend.commandline.command.CommandProcessorSwitch.caseExportJobCommand(CommandProcessorSwitch.java:94) at org.talend.commandline.client.util.CommandAbstractSwitch.doSwitch(CommandAbstractSwitch.java:66) at org.talend.commandline.command.CommandConsumer.executeCommand(CommandConsumer.java:57) at org.talend.commandline.command.CommandConsumer.execute(CommandConsumer.java:35) at org.talend.commandline.mode.ServerCommandLine$CommmandConsumerRunnable.run(ServerCommandLine...) at java.lang.Thread.run(Unknown Source)
