Couldn't "writeAll()"

Hello All,





I get the following exception when trying to use the chemaxon.jchem.db.Exporter;:








java.lang.NullPointerException


at chemaxon.jchem.db.TableInfo.getTableNameWithSchema(TableInfo.java:617)


at chemaxon.jchem.db.Exporter.init(Exporter.java:487)


at chemaxon.jchem.db.Exporter.writeAll(Exporter.java:359)


(...)





chemaxon.jchem.db.TransferException


at chemaxon.jchem.db.Exporter.init(Exporter.java:508)


at chemaxon.jchem.db.Exporter.writeAll(Exporter.java:359)


(...)

Code:

ConnectionHandler conHandler = new ConnectionHandler(); conHandler.setUrl(jdbcURL); conHandler.setDriver(jdbcDriver); conHandler.setLoginName(jdbcUser); jcex.setConnectionHandler(conHandler); jcex.setTableName(structureTable); FileOutputStream fos = new FileOutputStream(fname); jcex.setOutputStream(fos); jcex.writeAll();

Did I forget any parameter setting?





(I am using jchem3.2 & mysql 4.1.22 on RHEL v4.)

Hi,





Please call ConnectionHandler.connect() to create the JDBC connection before using it.


ConnectionHandler.close() closes the connection.





Best regards,
