Try to use my own project classes in ireport

2003-05-30 05:27

Hi,

My new challenge, use my own project classes in IReport. IÂ’m using IReport version 0.1.0, I create a report with sub-report. Everything is working fine. I have currency value in my sub-report. In my project, I have a class that format the currency.

 

So, in IReport in the TextField Tool in the field TextField expression I wrote:

 

com.isiconseil.framework.utils.DisplayFormat.signedMoney($F{amount})

 

I make the process to test the result in IReport, everything is working, and my class formats the amount. (IÂ’m very happy).

 

Now I try it in Tomcat. When the report is compiling I get the following error:

 

package com.isiconseil.framework.utils does not exist

value = (java.lang.String)(com.isiconseil.framework.utils.DisplayFormat.signedMoney(

((java.lang.String)field_amount.getValue())));

 

My java files are in the java folder and the class files are in the classes folder.

EX:

 

..projectsrcjava my java file

..projectsrcWEB-INFclasses my class file

 

I modify the System.setProperty("jasper.reports.compile.temp", “”) with the 2 paths to known if the root path of my classes was wrong.

 

I donÂ’t known if someone has an idea of what I did wrong?

 

Thanks

 

Simon

Try one of this:

 

1. Try to copy your currency formatter class in tomcat/classes/com/isiconseil/framework/utils

 

2. Try to add explicitally your classes directory to the classpath adding a line in the script that start Tomcat

P.S. We do the same thing to format other types of field and all run ok using Tomcat

Hi,

 

I can't modify the classpath because we have more than one application on the server. The production team wont want that I modify the classpath of the server. So I can’t use the System.setProperty("jasper.reports.compile.temp", “path”); configuration.

My question is about Tomcat. I donÂ’t known if I can post my question here?

With the call System.getProperty("user.dir"); The application will create the java file in the root folder of tomcat. It is the place where the java file is supposed to be creating?

When tomcat compile the java file, it is suppose to use all jar file in the lib folder and the class files in the classes folder? The application can find the class(HelloWorld.class) that I place in the classes folder of Tomcat, but when I call JasperCompileManager.compileReportToFile(reportNameFile); it never find the class.

If someone have a solution.

 

Thanks

Generally, you have not to compile the report every time you fill it...

 

However, try to put your classes in jasperreports jar. In this way, if you can compile (=you can call JasperCompileManager.compileReportToFile without problems), you'll find your classes too.

If I understand I can create the java file, compile them with jbuilder one time. Place them in the root of my project (in the good package..) and call another method to generate the report.

 

If it is right, what is the way?

Yes, jasperreport work as a java program...follow me....

To write a java program you create a java source, compile it one time and then you executei trought the JVM any time you want.

In a similar way you create the report source (the XML), compile it (the result is not a java class but a jasper file, like myreport.jasper), then, trought the jasperreports API you can fill your report using few lines of code....

 

Example:

 

String reportFile = "path/to/your/reports/MyReport.jasper";

 

dori.jasper.engine.JasperPrint print=null;

dori.jasper.engine.JasperReport report = dori.jasper.engine.JasperManager.loadReport(cl.getResourceAsStream( reportFile ));

print = dori.jasper.engine.JasperFillManager.fillReport( report , map,this.getConnection());

 

The print object resulted can be exported in PDF, XLS,....

 

As you can see, we assume that exist an already compiled report called MyReport.jasper (compiled i.e. from iReport starting from MyReport.xml two weeks ago...)
