hi, everybody

Page 206: Next you need to compile the report. You can do so by using the class com.opensymphony.webwork.views.jasperreports.CompileReport.

 

but i have a error when compiling, the error log is:

 

JasperReports Compiling: D:/workspace/HelloWebwork/resources/users.xml

java.io.FileNotFoundException: D:workspaceHelloWebworkusers.class (系统找ä¸åˆ°æŒ‡å®šçš„文件。)

and my definition file is users.xml:

 

<?xml version="1.0"?>

<!DOCTYPE jasperReport PUBLIC "-//JasperReports//DTD Report Design//EN" "http://jasperreports.sourceforge.net/dtds/jasperreport.dtd">

<jasperReport name="users">

...

 

Could you help me? thanks.

 

I use the IDE(eclipse RCP), and run the command with the ide's application model. the command detail is:

java -classpath "....." com.opensymphony.webwork.views.jasperreports.CompileReport D:/workspace/HelloWebwork/resources/users.xml

 

and i'm sure the command is right. but what 's the problem?

the line in the users.xml:

<jasperReport name="users">...</jasperReport>

and the line in the error logs:

java.io.FileNotFoundException: D:workspaceHelloWebworkusers.class

 

what's the relation between the name attribute and the error?

So sorry for my poor english:)
