Error Filling Print ... ?

2005-05-31 12:55

I created an iReport report that compiled with no problems. However, when I attempt to run it, I get beaucoup error messages, all under the general title of "Error Filling Print...", and an admonition of "Print not filled. Try to use an EmptyDataSource."

 

It would appear that the program is having lots of problems finding classes.

 

Can anybody shed some light on this problem?

I had a similar problem, may or may not be related. I had emailed Giulio Toffoli about the problem, but he wasn't immediately able to offer suggestions...perhaps someone could shed some light onto this? It looks as if the stack trace is saying that it's trying to open the connection as an FTP connection, which is just wrong. I have verified that the report it is trying to load actually exists...

 

Here's the stack trace:

Some more information...

 

I ran the same query, to the same database, over the same connection, using the ClassicC template.

 

I got a clean compile, and I encountered no problems when I generated a report.

Giulio,

All of my reports are in the same directory, and my subreports are named simply as "my_subreport_file_name.jasper" in the subreport expression field. This worked fine when I ran the reports after they were compiled with 0.4.1, but continually fail after the reports were compiled with 0.5.0.

I did a little more experimentation last night with the subreport and found something interesting -- the "my_subreport_file_name.jasper" subreport expression seems to be expanding to

 

file://c:/ireport-0.5.0/my_subreport_file_name.jasper

 

which is incorrect. There needs to be three slashes before the c: to access the file correctly. When I hardcoded the path above with three slashes before the c:, it worked like a dream.

 

Thanks,

Chris

One other interesting thing...

 

I tried compiling the main report with the subreport expression as "my_subreport_file_name.jasper" in 0.5.0 running in Linux along with the subreport -- the report ran and exported just as it did in 0.4.1. Something in 0.5.0 is causing this in Windows, is my guess.

I'm in the same boat as ccureau - report with subreport, jasper files for both in the same directory (along with xml) .

 

In the 0.4.1 version of iReport (and in my web application) it works, but in 0.5.0 a "java.net.UnknownHostException: C" is thrown (further down in the stack trace

"net.sf.jasperreports.engine.JRException: Error loading object from URL : file://C:/reportpath/subreport.jasper"

 

This is different from when the subreport cannot be found (or doesn't exist - "Could not load object from location...").

 

I tried to do a little debugging last night and although did not accomplish much, I did notice that the way iReport is handling the report filenames is different: In 0.4.1 the value stored in the fileName variable in the IReportCompiler.run() method was formatted like "c:reportpathreportname.jasper" whereas in 0.5.0 it is formatted like "/reportpath/reportname.jasper" - drive letter is stripped off and different separators.

 

I wonder if the difference in the formatting of the report name is causing problems later on for the class loader to find the jasper file?

ReportClassLoader.java (around line 206) creates a new URL object passing in a string of "file://" + path + filename, and it appears that in Windows the path is resolving to "/c:/pathtoreport.../" which means the concatenated string equals "file:///c:/pathtoreport.../". The URL host attribute then gets set to "c" instead of "".

 

By removing the second slash from "file://" (e.g., making it "file:/" instead) seems to work properly in Windows.

 

Anyone care to test this in Linux and post the results? Chris?

I've hardcoded the Subreport Expression field in Linux to

 

"file:/home/chrisc/oereports/subreport.jasper"

 

and tested -- both the compile and the export works as expected. I think you've found the solution, Brett. :-)

Thanks Chris.

 

After seeing your response I passed a message along to Giulio who immediately responded that he would look at it as soon as he could and put a fix into CVS.

 

So any other Windows users with this problem - be patient, a fix is on the way (or if you can't wait then download the source and make the change yourself in the interim).

 

BTW, 0.5.0 is very nice relative to 0.4.1. The latter was good, but the former is much better.

I committed in CVS the solution proposed by Chris and Brett.

 

If you can, try it.

 

Thanks

This kind of probleam (strange FTP/HTTP connections) appears specifing a wrong path to find a resource.

 

If you use an expression on type "String" to locate a resource (i.e. a subreport jasper file or an image) use the syntax:

 

c:\my\file.jasper

 

or, if your resource is in the classpath:

 

/path/to/my/resource.jasper

 

This is because if you have all reports in the same directory, you can simply write as subreport expression:

 

"my_subreport_file_name.jasper"

I have the same problem!

"images\novo-4.gif"

 

Windows XP works, but in linux I get this error:

 

Error filling print...

If I change de expression to:

"images//novo-4.gif"

 

on windows Xp works and linux give me another error:
