Error compiling report java source file

2005-03-22 07:49

Hi, i was searching here for any similar questions, but unfortunately nothing found, so pls help me, what is wrong...maybe i have not understood the system of JReports...

 

Well, i ve created the XML file for JasperDesign, in the tag <jasperReport name="BasicReport" >, but i cant create from it the JasperReport - i cant compile it. The exception is :

net.sf.jasperreports.engine.JRException: Error compiling report java source file : C:...SampleBasicReport.java. I dont have such java file, i dont understand why it wants to compile it. The XML is called BasicReport.xml. <b>Thnx</b> for any help.

Is your jrxml file called BasicReport.jrxml? I remember having some trouble when I named the report one thing but had the file saved as another... don't think it was the same problem you are having tho. Guess I'll echo and say "check out the samples", as that's really the bestest way to find out what is going on.

 

Have Fun!

Thanx,, for the answer maybe problem was in the ending of the file. well, now i have new exception :

I ve downloaded form JasperReport Home Page one sample, only for compiling - MasterReport.jrxml

 

This is what i have in the code

 

JasperDesign jasperDesign = JasperManager.loadDesign("MasterReport.jrxml");

JasperReport jasperReport = JasperManager.compileReport(jasperDesign);

 

and now the Exception is following :

 

net.sf.jasperreports.engine.JRException: Error loading object from file : MasterReport.jrxml

at net.sf.jasperreports.engine.util.JRLoader.loadObject(Unknown Source)

at net.sf.jasperreports.engine.util.JRLoader.loadObject(Unknown Source)

at basic2.main(basic2.java:65)

Caused by: java.io.StreamCorruptedException: invalid stream header

at java.io.ObjectInputStream.readStreamHeader(Unknown Source)

at java.io.ObjectInputStream.<init>(Unknown Source)

 

Any ideas, thanx a lot for any kind of help :-)

Thanx xenden to you too :)

I have done some investigations into this question. that a fix is to include jdt-compiler.jar file in your Java Project Referenced Libraries.

http://www.java2s.com/Code/Jar/j/Downloadjdtcompilerjar.htm this is the link where you can download the jdt-compiler.jar file.
