exception: java.lang.NoSuchMethodError: com.lowagie.text.pdf.PdfWriter.setRgbTransparencyBlending(Z)V

Question

guys! For long time I can't fix the exception: java.lang.NoSuchMethodError: com.lowagie.text.pdf.PdfWriter.setRgbTransparencyBlending(Z)V

I've add all need jars into classpath:

• commons-beanutils-1.8.0
• commons-collections-2.1.1
• commons-digester-2.1.0
• commons-javaflow-20060411
• commons-logging-1.1.1
• itext - 2.1.5
• jasperreports - 5.1.0

I saw requirements for JasperReports here, so I've all need libraries, but, anyway, I can't fix the bug

My code:

    class ForIReport {

    public static void main(String[] args) {

//        def conn = Sql.newInstance(
//                "jdbc:sqlserver://localhost:1433;databaseName=twitter",
//                'sa',
//                'sunrise123',
//                'com.microsoft.sqlserver.jdbc.SQLServerDriver')

//        Class.forName("com.microsoft.jdbc.SQLServerDriver").newInstance();
//        Connection conn = DriverManager.getConnection("jdbc:microsoft:sqlserver://localhost:1433", 'sa', 'sunrise123');

        def fileName = "C:/Users/avalev/Documents/iReport/First.jasper"

        def outFileName = "First.pdf"

        HashMap hm = new HashMap()

        JasperPrint print = JasperFillManager.fillReport(fileName, hm, new JREmptyDataSource())


        JRExporter exporter = new JRPdfExporter()

        exporter.setParameter(
                JRExporterParameter.OUTPUT_FILE_NAME,
                outFileName);

        exporter.setParameter(JRExporterParameter.JASPER_PRINT, print)

        exporter.exportReport()

        println("Created file :" + outFileName)

    }

}

and description of exception

I can create the instance of PdfWriter class (for check myself)

Thank you for your help

Answer 1

jasperreports-5.1.0 needs itext-2.1.7.

You can see it in the pom of the jasperreports-5.1.0 project:

<dependency>
    <groupId>com.lowagie</groupId>
    <artifactId>itext</artifactId>
    <version>2.1.7.js2</version>
    <scope>compile</scope>
</dependency>

You need to upgrade the version of itext to version 2.1.7 minimum.
