Groovy e JDBC Connection con Jaspersoft Studio

Question

Provo a utilizzare Groovy per il mio report per connettere una sottodataset a un database Oracle.

-> In Report> Proprietà> Lingua: Groovy

-> Nel mio set di dati scelgo "Usa un'altra connessione" con l'espressione:

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

.

I miei parametri (IP, Porta, Utente, Password) sono corretti, ho già fatto questo Java e funziona, ma ho bisogno di farlo con Groovy: (

Quando in anteprima il report (usando Groovy) ottengo questo seguente errore:

net.sf.jasperreports.engine.JRException: net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression :
    Source text : Sql.newInstance(

                    "pw",

                    "oracle.jdbc.driver.OracleDriver"

Prima di tutto, grazie per le tue risposte.

groovy.sql.Sql.newInstance("jdbc:oracle:thin:@ip:1521:XE", "user", "pw", "oracle.jdbc.driver.OracleDriver")

.

Sembra essere la buona espressione: funziona quando provo a connettermi al mio database con GroovyConsole.bat.

Ma sono sempre andati a connetterti al mio database Oracle da Jasperstudio e non so perché.

Ho avuto ojdbc14-1.0.jar al mio percorso di costruzione (stesso vaso che ho usato con Java JDBC Connection e funzionava)

Ho avuto Groovy-SQL-2.3.6.jar al mio percorso di costruzione (poi tutto .jar da Groovy perché ero "senza speranza" ma non ha cambiato nulla)

-> In Report> Proprietà> Lingua: Groovy

-> Nel mio set di dati scelgo "Usa un'altra connessione" con l'espressione:

groovy.sql.Sql.newInstance("jdbc:oracle:thin:@ip:1521:XE", "user", "pw", "oracle.jdbc.driver.OracleDriver")

.

Non funziona ancora, ottengo il seguente errore nel palcoscenico "Rapporto di riempimento" dopo l'anteprima:

Provo anche con "/ XE" ma non funziona neanche.

Non so cosa sto facendo male, qualsiasi idea?

Grazie per l'aiuto! :)

Answer 1

Sostituisci questo:

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

.

Con questo:

groovy.sql.Sql.newInstance("jdbc:oracle:thin:@ip:1521:XE", "user", "pw", 
        "oracle.jdbc.driver.OracleDriver")

.
