Hi All
I have a 19c Oracle Database with the following specifications
SELECT * from v$version;
Oracle Database 19c Standard Edition 2 Release 19.0.0.0.0 - Production
SELECT dbms_java.get_jdk_version JDK_Version FROM dual;
1.8.0_201
OS : Windows Server 2016
Installed Java jdk1.7.0_80 and jdk-9.0.1
I have Created A java Code with eclipse to print reports and merge the printed reports to one PDF.
I tested it and it works fine. Then i loaded it to Database with all dependence using loadjava
The Class created successfully without any compilation error and its status is VALID
create or replace and compile java source named MergePDFJava As

String dir = "E:/printedresults/";
List\<JasperPrint> jasperPrintList = new ArrayList\<>();
Connection conn = getOracleConnection();
String\[\] report\_name\_array = report\_name.split(",", 100);
String\[\] visitid\_array = visit\_id.split(",", 100);
String\[\] pid\_array = pid.split(",", 100);

Map\<String, Object> parameters = new HashMap\<>();
parameters.put("PVisitID", visitid\_array\[i\]);
parameters.put("PID", pid\_array\[i\]);
JasperReport jr = JasperCompileManager.compileReport(Report);
JasperPrint jp1 = JasperFillManager.fillReport(jr, parameters,conn);
jasperPrintList.add(jp1);
}
JRPdfExporter exporter = new JRPdfExporter();
exporter.setExporterInput(SimpleExporterInput.getInstance(jasperPrintList));
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(dir +file\_name +".pdf"));
SimplePdfExporterConfiguration configuration = new SimplePdfExporterConfiguration();
exporter.setConfiguration(configuration);
exporter.exportReport();
return "Printing...";
}
public static Connection getOracleConnection()
throws ClassNotFoundException, SQLException {
String hostName = "server";
String sid = "orclpdb";
String userName = "username";
String password = "password";
return getOracleConnection(hostName, sid, userName, password);
}
public static Connection getOracleConnection(String hostName, String sid,
String userName, String password) throws ClassNotFoundException,
SQLException {
Class.forName("oracle.jdbc.driver.OracleDriver");
String connectionURL = "jdbc:oracle:thin:@" + hostName + ":1521/" + sid;
Connection conn = DriverManager.getConnection(connectionURL, userName,
password);
return conn;
}
}
Then I created a Function as
create or replace FUNCTION portal_print_result (
file_name VARCHAR2,
report_name VARCHAR2,
visit_id VARCHAR2,
pid VARCHAR2
) RETURN VARCHAR2 AS LANGUAGE JAVA NAME 'MergePDFJava.combineReports( java.lang.String, java.lang.String, java.lang.String, java.lang.String ) return java.lang.String ';
and it's created successfully without errors
and while execution i got the below error
DECLARE
x CLOB;
BEGIN
x := portal_print_result(
'45896',
'Dental_Lab_Order.jasper,Dental_Lab_Order.jasper',
'8615,8572',
'48,21'
);
END;
