Error with web application (Eclipse, Spring, GWT) - reportUnusedDeclaredThrownExceptionIncludeDocCommentReference

Question

I am using spring 3.0.5 and try to run my webapp in eclipse. When I start the application in tomcat we get this exception:

java.lang.NoSuchFieldError: reportUnusedDeclaredThrownExceptionIncludeDocCommentReference

This project is imported through CVS. It start normally on my computer (Win7 64bit), but throws above given error on coleague's computer (Win XP). I don't know if that matters at all.

Any suggestions?

Answer 1

This looks like some jars are clashing.

Make sure your Eclipse gives priority to GWT hosted mode libraries.

Go to your GWT project properties (In project Explorer right click on the project and select Properties). Then navigate to Java Build Path->Order And Export tab. Move the GWT SDK bundle above any other library (i.e. it should be above the JRE libraries and any other libs you may have - maven libs etc).

This should solve you problem.

Sorry guys......this is a JASPER integration issue. This issue started occurring after I integrated Maven + GWT 2.5.0 with Jasper 4.6.0.

Moving the GWT SDK bundle to the top allows Tomcat to build without any errors, but I was unable to start web application using RunAs --> webapplication from eclipse (STS).

Added the exclusion for jdtcore and this fixed the Tomcat build + Running Webapplication from STS.

   <dependency>
    <groupId>net.sf.jasperreports</groupId>
    <artifactId>jasperreports</artifactId>
    <version>4.6.0</version>
        <exclusions> 
           <exclusion> 
             <artifactId>jdtcore</artifactId> 
             <groupId>eclipse</groupId> 
           </exclusion> 
        </exclusions> 
</dependency>
