Groovy and jdbc connection in a report

[Pollux Us]

Hi

I try to use groovy for my report to connect a subdataset to an Oracle database.

-> In report > properties> language : i selected groovy

-> in my dataset i choose "use an other connection" with the expression :

Sql.newInstance(                    "jdbc:oracle:thin:@ip:1521:XE",                    "user",                    "pw",                    "oracle.jdbc.driver.OracleDriver"                )[/code]

When i preview the report i get this following error :

net.sf.jasperreports.engine.JRException: net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression :    Source text : Sql.newInstance(                    "jdbc:oracle:thin:@ip:1521:XE",                    "user",                    "pw",                    "oracle.jdbc.driver.OracleDriver"                )    at com.jaspersoft.studio.editor.preview.view.control.ReportControler.fillReport(ReportControler.java:466)    at com.jaspersoft.studio.editor.preview.view.control.ReportControler.access$18(ReportControler.java:441)    at com.jaspersoft.studio.editor.preview.view.control.ReportControler$4.run(ReportControler.java:333)    at org.eclipse.core.internal.jobs.Worker.run(Worker.java:53)Caused by: net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression :    Source text : Sql.newInstance(                    "jdbc:oracle:thin:@ip:1521:XE",                    "user",                    "pw",                    "oracle.jdbc.driver.OracleDriver"                )    at net.sf.jasperreports.engine.fill.JREvaluator.evaluate(JREvaluator.java:263)    at net.sf.jasperreports.engine.fill.JRCalculator.evaluate(JRCalculator.java:611)    at net.sf.jasperreports.engine.fill.JRCalculator.evaluate(JRCalculator.java:579)    at net.sf.jasperreports.engine.fill.JRFillElement.evaluateExpression(JRFillElement.java:1016)    at net.sf.jasperreports.engine.fill.JRFillSubreport.evaluateSubreport(JRFillSubreport.java:392)    at net.sf.jasperreports.components.table.fill.FillTableSubreport.evaluateSubreport(FillTableSubreport.java:92)    at net.sf.jasperreports.components.table.fill.FillTable.evaluate(FillTable.java:118)    at net.sf.jasperreports.engine.fill.JRFillComponentElement.evaluate(JRFillComponentElement.java:110)    at net.sf.jasperreports.engine.fill.JRFillElementContainer.evaluate(JRFillElementContainer.java:259)    at net.sf.jasperreports.engine.fill.JRFillBand.evaluate(JRFillBand.java:456)    at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillColumnBand(JRVerticalFiller.java:2067)    at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillDetail(JRVerticalFiller.java:788)    at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReportStart(JRVerticalFiller.java:298)    at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReport(JRVerticalFiller.java:152)    at net.sf.jasperreports.engine.fill.JRBaseFiller.fill(JRBaseFiller.java:963)    at net.sf.jasperreports.engine.fill.BaseFillHandle$ReportFiller.run(BaseFillHandle.java:120)    at java.lang.Thread.run(Unknown Source)Caused by: groovy.lang.MissingPropertyException: No such property: Sql for class: reportFacturation_1406640568882_851084    at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:50)    at org.codehaus.groovy.runtime.callsite.GetEffectivePogoPropertySite.getProperty(GetEffectivePogoPropertySite.java:86)    at org.codehaus.groovy.runtime.callsite.AbstractCallSite.callGroovyObjectGetProperty(AbstractCallSite.java:231)    at reportFacturation_1406640568882_851084.evaluate(calculator_reportFacturation_1406640568882_851084:263)    at net.sf.jasperreports.engine.fill.JREvaluator.evaluate(JREvaluator.java:250)    ... 16 more[/code]
