2. Re: hook the JBPM engine to JBOSS
yairfr Aug 9, 2007 3:05 AM (in response to yairfr)1. thanks for the answer
2. i wrote a hook function :protected void hookFunc() { logger.debug("hookFunc::Start"); conf = JbpmConfiguration.getInstance(); context = conf.createJbpmContext(); graphSession = context.getGraphSession(); //context.close(); logger.debug("hookFunc::End"); }
it run ok , but both option : with context.close() or without it
resulted in an error when i tried to run continue or start a process .
without the close it gives this error :09:49:19,039 INFO [STDOUT] 09:49:18,367 [Thread-25] DEBUG Log4JLogger : adding converter 'D', 'org.jbpm.context.exe.converter.DoubleToStringConverter' 09:49:19,164 INFO [STDOUT] 09:49:19,164 [Thread-25] DEBUG Log4JLogger : adding converter 'C', 'org.jbpm.context.exe.converter.CharacterToStringConverter' 09:49:19,179 INFO [STDOUT] 09:49:19,179 [Thread-25] DEBUG Log4JLogger : adding converter 'B', 'org.jbpm.context.exe.converter.BooleanToStringConverter' 09:49:19,179 INFO [STDOUT] 09:49:19,179 [Thread-25] DEBUG Log4JLogger : adding converter 'Y', 'org.jbpm.context.exe.converter.BytesToByteArrayConverter' 09:49:19,179 INFO [STDOUT] 09:49:19,179 [Thread-25] DEBUG Log4JLogger : adding converter 'A', 'org.jbpm.context.exe.converter.DateToLongConverter' 09:49:19,195 INFO [STDOUT] 09:49:19,195 [Thread-25] DEBUG Log4JLogger : adding converter 'R', 'org.jbpm.context.exe.converter.SerializableToByteArrayConverter' 09:49:19,211 INFO [STDOUT] 09:49:19,211 [Thread-25] DEBUG Log4JLogger : adding converter 'I', 'org.jbpm.context.exe.converter.IntegerToLongConverter' 09:49:19,211 INFO [STDOUT] 09:49:19,211 [Thread-25] DEBUG Log4JLogger : adding converter 'H', 'org.jbpm.context.exe.converter.ShortToLongConverter' 09:49:19,211 INFO [STDOUT] 09:49:19,211 [Thread-25] DEBUG Log4JLogger : adding converter 'G', 'org.jbpm.context.exe.converter.FloatToDoubleConverter' 09:49:19,226 INFO [STDOUT] 09:49:19,226 [Thread-25] DEBUG Log4JLogger : adding converter 'F', 'org.jbpm.context.exe.converter.FloatToStringConverter' 09:49:19,242 INFO [STDOUT] 09:49:19,226 [Thread-25] DEBUG Log4JLogger : adding converter 'E', 'org.jbpm.context.exe.converter.ByteToLongConverter' 09:49:19,273 INFO [STDOUT] 09:49:19,273 [Thread-25] DEBUG LogUtil : RequestsHandler:writeTasks():End 09:49:19,273 INFO [STDOUT] 09:49:19,273 [Thread-25] DEBUG Log4JLogger : executing default save operations 09:49:19,304 INFO [STDOUT] 09:49:19,273 [Thread-25] DEBUG Log4JLogger : saving process instance 09:49:19,320 INFO [STDOUT] 09:49:19,320 [Thread-25] DEBUG Log4JLogger : ignoring logs. no logging service available. 09:49:19,320 INFO [STDOUT] 09:49:19,320 [Thread-25] DEBUG Log4JLogger : cascading save of 'org.jbpm.graph.exe.ProcessInstance@1a22e94' 09:49:19,320 INFO [STDOUT] 09:49:19,320 [Thread-25] DEBUG Log4JLogger : closing JbpmContext 09:49:19,320 INFO [STDOUT] 09:49:19,320 [Thread-25] DEBUG Log4JLogger : closing service 'persistence': org.jbpm.persistence.db.DbPersistenceService@13beb64 09:49:19,320 INFO [STDOUT] 09:49:19,320 [Thread-25] DEBUG Log4JLogger : committing hibernate transaction 09:49:19,367 INFO [STDOUT] Hibernate: insert into JBPM_TASKINSTANCE (NAME_, DESCRIPTION_, ACTORID_, CREATE_, START_, END_, DUEDATE_, PRIORITY_, ISCANCELLED_, ISSUSPENDED_, ISOPEN_, ISSIGNALLING_, ISBLOCKING_, TASK_, TOKEN_, SWIMLANINSTANCE_, TASKMGMTINSTANCE_, CLASS_, ID_) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, 'T', ?) 09:49:19,383 INFO [STDOUT] Hibernate: update JBPM_TASKINSTANCE set NAME_=?, DESCRIPTION_=?, ACTORID_=?, CREATE_=?, START_=?, END_=?, DUEDATE_=?, PRIORITY_=?, ISCANCELLED_=?, ISSUSPENDED_=?, ISOPEN_=?, ISSIGNALLING_=?, ISBLOCKING_=?, TASK_=?, TOKEN_=?, SWIMLANINSTANCE_=?, TASKMGMTINSTANCE_=?
