Hi,

I am using dotcms osgi job plugin to schedule jobs.Running a single job is working fine.But when I create multiple cron jobs using the same job class,I get the below error,

Can anyone advice/comment here. Below is the code.The first scheduling of job works fine but error arises when second job is scheduled.

Error while starting bundle: file:/C:/D%20Drive/core-3.1/core-3.1/build/war/dotcms/WEB-INF/felix/load/VaultFetchFiles-Plugin-1.0.jar: com.dotcms.repackage.org.osgi.framework.BundleException: Activator start error in bundle vaultSharedDriveJobOSGI [8]

I have implemented a dynamic plugin in dotcms 3.2 and scheduled a cron job.

private final static String STUDIES_JOB = "Study Job";

private final static String STUDIES_JOB = "com.plugins.dynamic.StuiesJob";

private final static String STUDIES_GROUP = "Studies";

private final static String JOB_SCHEDULE = "0 5 0/1 * * ?";

public void start(BundleContext context) throws Exception {

registerTrials(context);

// Job params

Map<String, Object> params = new HashMap<String, Object>();

// Creating our custom Quartz Job

CronScheduledTask cronScheduledTask = new CronScheduledTask(

STUDIES_JOB, STUDIES_GROUP, STUDIES_JOB,

STUDIES_JOB, new Date(), null,

CronTrigger.MISFIRE_INSTRUCTION_FIRE_ONCE_NOW, params,

JOB_SCHEDULE);

scheduleQuartzJob(cronScheduledTask);

}
