load and compile an xml-File

2003-09-12 00:51

hello,

 

I've got the following code:

 

JasperDesign jasperDesign = JasperManager.loadXmlDesign("C:\temp\report.xml");

JasperReport jasperReport = JasperManager.compileReport(jasperDesign);

 

 

But this error occurs and I don't no why:

(line 37 is the line "JasperManager.compileReport(jasperDesign);")

I have find out, that in the method 'compileReport' of the JasperManager, the JRDefaultCompiler is used.

 

But if this compiler is used, my *.java-file is deleted (but I don't know why!! Perhaps it is a bug?)

 

So I used instead of the JasperManager the JRBshCompiler with his method 'compileReport(jasperdesign)

and it runs.

Hi,

 

The JRBshCompiler is very different from the other

Java compilers inside JasperReports.

When compiling reports with the BeanShell compiler

the report expressions will be evaluated using the

BeahShell library at runtime.

As oposed to the other bytecode compilers that

use a Java compiler to compile a class containing

the report expressions.

 

The fact that the temporary generated java file

is deleted after report compilation is not a bug.

If you want to keep this file you can set the

"jasper.reports.compile.keep.java.file" system property to true, as explained here:

 

http://jasperreports.sourceforge.net/quick.how.to.html#compile

 

I hope this helps.

hi Teodor,

 

thanks for your help.

 

But when I set this system property "jasper.reports.compile.keep.java.file" to true, I keep the .java.-File, but this .java-File doesn't have anymore the main-method (and in the main-method I create the jasperdesign,the report etc). The .java-File, which is created, has another content than my file ( and my file normally has 2 KB and the created .java-File has 10 kb).

 

It means, that after running my .java-File and creating a pdf-report, I will have other .java-file and can?t run it once again.

 

What's going wrong here?

thanks for help!

Loading .jasper file from .ear file

2003-10-01 21:09

hi

can some one tell me how to load the .jasper file from the ear file.

 

JasperRunManager.runReportToPdfFile("TermClaimDocument.jasper", "c://RMReports//" + termClaim.getClaimType()+ termClaim.getClaimNo() + "Report.pdf", printParams, new JRBeanCollectionDataSource(termClaimLines));

 

The following gives me a zip file corrupt exception.

 

Thanks

RE: Loading .jasper file from .ear file

2003-10-05 05:03

 

Hi,

 

If the *.jasper file is inside an EAR file, then the best

solution is to try to load the JasperReport object from

it considering this file is in fact available in the

application's classpath.

 

Loading a JasperReport object from a *.jasper files

available in the classpath can be done using the

JRLoader.loadObjectFromLocation(String), giving

the classpath location of the file as the parameter.

 

Once the JasperReport object loaded, the report can

be filler using the JasperFillManager and exported

using the JasperExporterManager classes, since the

JasperRunManager does not seem to offer the

appropriate methods.

 

I hope this helps.

Teodor

RE: Loading .jasper file from .ear file

2003-10-07 16:49

I tried specifying the location of the .jasper file.

 

JasperReport report = (JasperReport) JRLoader.loadObjectFromLocation("/reports/");

and I get exception following

 

>java.io.StreamCorruptedException at java.io.ObjectInputStream.readTypeString(ObjectInputStream.java:1347) at java.io.ObjectStreamClass.readNonProxy(ObjectStreamClass.java:536) at java.io.ObjectInputStream.readClassDescriptor(ObjectInputStream.java:762) at java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream.java:1503) at java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1435) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1626) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1274) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:324) at dori.jasper.engine.util.JRLoader.loadObject(JRLoader.java:163) at dori.jasper.engine.util.JRLoader.loadObjectFromLocation(JRLoader.java:243) at

 

I would greatly appreciate if you could help me on this.

 

Thanks

Urgent: Loading .jasper file from .ear file

2003-10-08 16:08

JasperReport report = (JasperReport) JRLoader.loadObjectFromLocation("/reports/Test.jasper");

 

This is what i have tried and i keep getting ->

java.io.StreamCorruptedException at java.io.ObjectInputStream.readTypeString(ObjectInputStream.java:1347) at java.io.ObjectStreamClass.readNonProxy(ObjectStreamClass.java:536) at java.io.ObjectInputStream.readClassDescriptor(ObjectInputStream.java:762) at java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream.java:1503) at java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1435) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1626) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1274) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:324) at dori.jasper.engine.util.JRLoader.loadObject(JRLoader.java:163) at dori.jasper.engine.util.JRLoader.loadObjectFromLocation(JRLoader.java:243) at

 

Other config files that are been used by other frameworks get loaded. But this keep giving me the following exception.

 

If not can someone show me a code snippet on how to load these .jasper files within a ear file will be greatly appreciated.

 

Thanks

Hi Teodor,

 

I am still having the same problem of not been able to load the *.jasper file from the .ear file. It keeps comming with the streamcorrupt exception.

 

I tried the loadObjectFromLocation passing the full path and and the file name as "reports/test.jasper". This is very urgent and if you could help me with this is much appreciated. I am using weblogic 8.1.

 

Thanks
