Dear All,

I am trying to view report using jasper ..
but it does not work ..

what I missed?

Code:

---

JasperDesign jasperDesign = JRXmlLoader.load("myreport1.jrxml");
jasperReport = JasperCompileManager.compileReport(jasperDesign);
Connection jdbcConn = connectMySQL();
jasperPrint = JasperFillManager.fillReport(jasperReport, new
HashMap(), jdbcConn);
JasperViewer.viewReport(jasperPrint);

---

it thrown exception below:

First, I think you have to give the complete path of the report. Including drive and folder where your report is placed.

Code:

---

JasperDesign jasperDesign = JRXmlLoader.load("D:\\Folder\\anoterFolder\\folder_again\\report\\MyReport.jrxml");

---

Second,

Quote:

---

jasperReport = JasperCompileManager.compileReport(jasperDesign);
jasperPrint = JasperFillManager.fillReport(jasperReport, new HashMap(), jdbcConn);
JasperViewer.viewReport(jasperPrint);

---

??? I think you forgot to put variable name

Code:

---

JasperReport someReport= JasperCompileManager.compileReport(jasperDesign);
JasperPrint somePrint= JasperFillManager.fillReport(jasperReport, new HashMap(), jdbcConn);

---

And you can just pass null instead of "new HashMap()" in parameter.

Code:

---

JasperPrint somePrint= JasperFillManager.fillReport(jasperReport, null, jdbcConn);

---

Also, I did not see you declare JasperViewer.

Code:

---

JasperDesign jasperDesign = JRXmlLoader.load("C:\\project\\learnjava\\myreport1.jrxml");

JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);

Connection jdbcConn = connectMySQL();

JasperPrint  jasperPrint = JasperFillManager.fillReport(jasperReport, null, jdbcConn);
JasperViewer.viewReport(jasperPrint);

.viewReport method is static method .. so I should replace it with class reference.

and the problem still occurs..


any idea?

try this...

Code:

---

JasperViewer.viewReport(print, true);

---

the same problem still occurs...

Same Error message? Or nothing happens?

Did you already add the libraries needed?

jasperreports-fonts-3.7.4
jasperreports-javaflow-3.7.4
itext-2.1.7

try to create a small executable program that concerns/describes your problem. So we can run it in our pc

ok.. where should I send it?

not so sure but did you add spring.jar?

post it in this thread
