Error compiling report java source files

[sordonez]

Hi I´m trying to compile a report in this way

 

JasperReport report = JasperCompileManager.compileReport(this.getClass().getClassLoader().getResourceAsStream(resumenCorteComite.xml));

 

that instruction run well in a OC4J Container in Windows xp but when I try to run this one in a OC4J Container in a Solaris I get the follow error:

 

Caused by: java.io.IOException: javac: not found

Hi,

 

Just put the jdt-compiler.jar in the classpath of you application. You can find it in the /lib directory of the JR distribution package.

But first of all, I would make sure I really need to compile report templates at runtime. Usually you don't, as you can deploy *.jasper files as part of you application JAR files. Only when dealing with dynamic report templates you need runtime report compilation, but that is rather a rare occurrence.

 

I hope this helps.

Hi teodor, thanks for your answer. I will try to resolve the problem with the jdt-compiler.jar in the classpath

but I create my reports using:

 

JasperReport report =

JasperCompileManager.compileReport(this.getClass().getClassLoader() .getResourceAsStream(resumenCorteComite.xml));

 

JasperFillManager.fillReport(report, parameters, connection);

 

How can I create my object JasperReport using just the .jasper?

 

thanks again.

To load a report from a .jasper file (compiled report file), you would do something like

Code:

InputStream jasperResource = this.getClass().getClassLoader() .getResourceAsStream(...);
JasperReport report = (JasperReport) JRLoader.loadObject(jasperResource);

 

HTH,

Lucian

Why does it need this jar on UNIX/Linux? We are having this problem as well.

[lucianc]

See this FAQ. If you don't want to use the JDT compiler, make sure that the javac command is available on the process path, or that you have the JDK's tools.jar on the application's classpath.

Lucian
