NullPointerEx. when typing in report query

2004-11-04 01:30



we use iReport 0.3.2 and 0.4 and the Oracle thin client (9iR2) to connect to an Oracle db.

The connection test is OK. Than we open a new report document and start typing in a new report query like


select name, login from tablename


The OK button does not get clickable and the system output shows a NPE:


at it.businesslogic.ireport.gui.ReportQueryDialog.processQueryChanged(ReportQueryDialog.java:143)

at it.businesslogic.ireport.gui.ReportQueryDialog.automaticlyReadFieldsCheckBoxActionPerformed(ReportQueryDialog.java:1002)

at it.businesslogic.ireport.gui.ReportQueryDialog.access$1000(ReportQueryDialog.java:55)

at it.businesslogic.ireport.gui.ReportQueryDialog$6.actionPerformed(ReportQueryDialog.java:529)

at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:1786)




What are we doing wrong?

Sorry about bothering you. After searching the forum again I found the answer:


You have to set the active connection, use the menu "Build", "Set active connection"
