Migrate birt from version 4.4 to 4.9. The resource path [ /…/…]has been normalized to null which is not valid

Question

Error migrate birt 4.4 to 4.9 I have a problem when running a report where when opening the layout it is giving a

“The resource path [ /…/…]has been normalized to null which is not valid”

Do you have any idea what it could be?

I put the part of the source that the error happens and the error itself.

Src:

    InputStream fileLayout = new 
    ByteArrayInputStream(EntityUtils.toByteArray(methodLayoutReport.getEntity()));

    String reportEnder = servlet.getRealPath("Report/include/glw/view/report") + "/" + reportName
    + ".rptdesign";

    design = birtReportEngine.openReportDesign(reportEnder, fileLayout);//line error

ERROR:

INFO: Server startup in [23135] milliseconds
java.lang.IllegalArgumentException: The resource path [/WEB-INF/classes/…/…/…/…/estrutura/est_report_library_base.rptlibrary] has been normalized to [null] which is not valid

Answer 1

Just a wild guess: This might be caused by

a) security enhancements to avoid access to arbitrary files b) Incorrect setting of the resource path

Note that the error occurs when the report (or an intermediate library) tries to open the library est_report_library_base.rptlibrary . This means that the report itself was successfully found.

Answer 2

The problem was that as I was passing a relative path of the library in the report, it was trying to take the root path of the project, and as my root was "/WEB-INF/classes" there was no way to go back more than two levels, generating the error, thanks for the help. I'm kinda new to some things
