Error loading object from inputstream

I’m trying to generate pdf via button but my problem is this method
JasperRunManager.runReportToPdfStream(reportStream,servletOutputStream, new HashMap<Object, Object>(), resultSetDataSource);

it is not supporting Hashmap it gives following error

The method runReportToPdfStream(InputStream, OutputStream, Map<String,Object>, Connection) in the type JasperRunManager is 
 not applicable for the arguments (InputStream, ServletOutputStream, HashMap<Object,Object>, JRResultSetDataSource)

it Supports String parameter like Hashmap<String,Object> while generating pdf it gives following error

I have a problem when loading the servlet that would compile the jrxml and export it in a PDF format. I tested a sample jrxml that I found in a tutorial and put it in my CLASSES folder in WEB-INF togther with the servlet. The error occured when calling the servlet.

Problem with jasper report -loading stream

i am currently experimentating with ireport and jasper report. i have the following code:

public void display()
<
FileInputStream file = new FileInputStream(«D:\reports_jasper\JASPER\report1.jasper»);
System.out.println(«loading report.. file read «+file.available());

JasperReport jasperReport = (JasperReport) JRLoader.loadObject(file);
System.out.println(«Successfully created jasper report»);

try
<
Class.forName(«com.mysql.jdbc.Driver»).newInstance();
con = DriverManager.getConnection(«jdbc:mysql://localhost/eply»,
«user», «123»);

if(!con.isClosed())
System.out.println(«Successfully connected to MySQL server using TCP/IP. «);
>
catch(Exception e)
<
System.out.println(«Exception: «+ e);
>

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,null,con);

JasperViewer.viewReport(jasperPrint,false);
>
catch(Exception e)
<
System.out.println(«There is exception here»+ e);
>
>

When i run my code, it gives me an error like below:
loading report.. file read 14143
There is exception herenet.sf.jasperreports.engine.JRException: Error loading object from InputStream

It will never print successfully created jasper report.. so i guess it has to do with my loading of the jasper report file.

i use ireport to create my report and it compile the report1.jrxml into report1.jasper. i dun understand the error. i included the jasperreports-0.6.2.jar into my library which i run under eclipse. is there any other things that i miss out?

christina, you’ll probably find out more about your problem if you’ll print out the whole exception stacktrace. if this will not give you a better idea, try pasting it here and somebody might find out the issue.

Aee.. well. that’s it all that it prints out from my code inside the catch statement.
Doesn’t help much does it? How come i could not load the .jasper file? i search the net and almost all people got along well with the same code i have.

any advice? or suggestion?

christina I am pretty sure that some e.printStackTrace(); in catch blocks will reveal you more details ;-).

okie.. i paste that in the catch clause for JRException and this is wat it gives me. Brace yourself.. :

JasperReport error — Error loading object from InputStream — StreamCorruptedException: invalid stream header: 3C3F786D

Hello.
I’ve try use trivial JasperReport on art 3.11, but got error:

Additionally I can attach many SubReports, but do not see such files in report:
Only got error what it exists when try upload it again.

You could check in the WEB-INFworktemplates directory and see if the .jasper files are generated.

Sure, its are. My assumption was correct. If I upload again main jrxml file where for sub-reports provide instead of it works! But .jasper file appeared only after initially uploaded report with .jrxml . So, compilation happened, but then does not work in report.

So you got it to work finally?

Only with that ugly workaround. It does not work correctly.

It isn’t clear what the workaround is. Is setting the subreport as x.jasper enough.

It will not work first time because we upload only x.jrxml

ART compiles the .jrxml files to .jasper files when its running the report so it’s still not clear what could be happening. Does this happen for all jasper reports or just some, to isolate what the issue is.

Yes, ART compiles, but do not load compiled version by referred x.jrxml !
I try on fist trivial example and it does not work. So I do not create others. Do you want I upload it?

Since I don’t have the database you’re connecting to, I don’t think attaching the jrxml file will help. Does it have subreports?

Sure. Without subreports it works.

Could you upload the .jrxml files for the main and subreports.

I am trying to pass a list of objects on a subreport for our reports generation but I was getting this error message:

I tried different tutorials in regards to this matter but I am still getting the same error below is the sample structure of the main object being passed to the main report

    private String headerRecordFormat;
    private String institutionRecordFormat;
    private ArrayList<InstituionDetailFormatTransactions> listOfTransactions;
    private String institutionTrailerRecordFormat;

and this is how I currently declare the arraylist «listOfTransactions» to my main xml and using it on calling the subreport

<field name="listOfTransactions" class="java.util.ArrayList" >
        <fieldDescription><![CDATA[listOfTransactions]]></fieldDescription>
    </field>

                    <subreport>
                    <reportElement x="0" y="15" width="560" height="15">
                    </reportElement>
                    <dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{listOfTransactions})]]></dataSourceExpression>
                    <subreportExpression><![CDATA[$P{SUBREPORT_DIR} + "dpsPgpSubReport.jrxml"]]></subreportExpression>
                </subreport>

The object InstituionDetailFormatTransactions contains only one instance variable which is a type String. Are there any mistakes on my declaration on the xml?
