Hello, folks: I am new to ManifoldCF, and trying to make my own connector. For now, I could successfully build ManifoldCF including my own connector. However, when I tried to run, I have exceptions.
The exception I am facing is : org.apache.manifoldcf.core.interfaces.ManifoldCFException: integrity constraint violation: unique constraint or index violation: I1549774667196 at org.apache.manifoldcf.core.database.DBInterfaceHSQLDB.reinterpretException(DBInterfaceHSQLDB.java:734) at org.apache.manifoldcf.core.database.DBInterfaceHSQLDB.performModification(DBInterfaceHSQLDB.java:754) at org.apache.manifoldcf.core.database.DBInterfaceHSQLDB.performInsert(DBInterfaceHSQLDB.java:230) at org.apache.manifoldcf.core.database.BaseTable.performInsert(BaseTable.java:68) at org.apache.manifoldcf.crawler.connmgr.ConnectorManager.registerConnector(ConnectorManager.java:172) at org.apache.manifoldcf.crawler.system.ManifoldCF.registerConnectors(ManifoldCF.java:672) at org.apache.manifoldcf.crawler.system.ManifoldCF.reregisterAllConnectors(ManifoldCF.java:160) at org.apache.manifoldcf.jettyrunner.ManifoldCFJettyRunner.main(ManifoldCFJettyRunner.java:239) Caused by: java.sql.SQLIntegrityConstraintViolationException: integrity constraint violation: unique constraint or index violation: I1549774667196 at org.hsqldb.jdbc.JDBCUtil.sqlException(Unknown Source) at org.hsqldb.jdbc.JDBCUtil.sqlException(Unknown Source) at org.hsqldb.jdbc.JDBCPreparedStatement.fetchResult(Unknown Source) at org.hsqldb.jdbc.JDBCPreparedStatement.executeUpdate(Unknown Source) at org.apache.manifoldcf.core.database.Database.execute(Database.java:916) at org.apache.manifoldcf.core.database.Database$ExecuteQueryThread.run(Database.java:696) Caused by: org.hsqldb.HsqlException: integrity constraint violation: unique constraint or index violation: I1549774667196 at org.hsqldb.error.Error.error(Unknown Source) at org.hsqldb.error.Error.error(Unknown Source) at org.hsqldb.index.IndexAVL.insert(Unknown Source) at org.hsqldb.persist.RowStoreAVL.indexRow(Unknown Source) at org.hsqldb.persist.RowStoreAVLDisk.indexRow(Unknown Source) at org.hsqldb.TransactionManagerMVCC.addInsertAction(Unknown Source) at org.hsqldb.Session.addInsertAction(Unknown Source) at org.hsqldb.Table.insertSingleRow(Unknown Source) at org.hsqldb.StatementDML.insertSingleRow(Unknown Source) at org.hsqldb.StatementInsert.getResult(Unknown Source) at org.hsqldb.StatementDMQL.execute(Unknown Source) at org.hsqldb.Session.executeCompiledStatement(Unknown Source) at org.hsqldb.Session.execute(Unknown Source) ... 4 more I am guessing my class-path would have a problem, but do not have a confidence. What is the cause of this error? I would appreciate for any of your help. Sincerely, Kaya
