java.lang.NoClassDefFoundError: javax/swing/event/EventListenerList

[jordan78gallen]

Hello I am creating a web application. Part of this application uses the JFreeCharts api. I have the jar files required each referenced in my application by putting them in the jboss-deployment-structure.xml file.

For example:

<?xml version="1.0" encoding="UTF-8"?>

<jboss-deployment-structure>  

  <deployment>       

    <dependencies>        

          <module name="com.jfreechart" />    

           <module name="com.jcommon" /> 

           <module name="com.swtgraphics2d" />   

           <module name="com.gnujaxp" />   

           <module name="com.itext" /> 

           <module name="com.servlet"/>

      </dependencies> 

     </deployment>

</jboss-deployment-structure>

When I try run the web application I am getting this error. I believe it has something to do with the swing class in javax.servlet. But I have no idea how to reference this within the application. Any help would be greating appreciated thanks .

Tried a jboss-deployment-structure.xml with

            <dependencies>
                <system>
                    <paths>
                        <path name="javax/swing/event"/>

...

?

[jordan78gallen]

Thank you for the quick reply. I updated my jboss-deployment-structure.xml. So it now looks like this

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.0">

  <deployment>       

    <dependencies>        

          <module name="com.jfreechart" export="true"/>    

           <module name="com.jcommon" export="true"/> 

           <module name="com.swtgraphics2d" export="true" />   

           <module name="com.gnujaxp" export="true"/>   

           <module name="com.itext" export="true"/> 

           <module name="com.servlet" export="true"/>

         <system>

         <paths>

                <path name="javax/swing/event"/>

       </paths>

        </system>

             </dependencies> 

   </deployment>

</jboss-deployment-structure>

But this wont deploy the application now. it is say that there is a problem with the strucutre. What would be the correct structure? Thank you once again

_______________________________

Have it deploying now changed the jboss:deployment-structure:1.0 to jboss:deployment-structure:1.1.

But the problem with the java.lang.NoClassDefFoundError: javax/swing/event/EventListenerList is still showing up when I try to run.

Any ideas?

[nickarls]

What the stacktrace?

[nickarls]

Strange, I thought that should work. As a workaround, you can edit the path into the module.xml of the jdk module...

[jaikiran]

It's being added to the wrong place. Looking at the stacktrace, the com.jfreechart module is the one which requires that dependency. So adding that <system> element with the relevant paths in the module.xml of com.jfreechart module is what needs to be done.

[jordan78gallen]

Cheers you so much for that. Finally I have gotten passed that eventlistenlist problem .

But now I am getting a similar problem only this time with org/jfree/chart/plot/Plot

                                      </dependencies>

                   </module>

But the error is still coming up. Any ideas? once again thank you

[nickarls]

Is there a reason why you make all your libraries modules instead of sticking them into e.g. a WAR lib? Having said that, you shouldn't need any modifications to the jfreechart module.xml (the class missing should be in the jfreechart.jar and the system/paths is for rt.jar). The com.servlet module sounds omnious, what's in it?

[jordan78gallen]

The library that I am trying to use is called jfreecharts. From reading online I thought the correct way to implement this was to references the paths for the jars inside an xml document called jboss-deployment-stucture within the WEB-INF folder. The com.servlet module is a jar file which is included with the jfreecharts. Do you know of another way which I could implement this library?

[nickarls]

Put all the jars in your WAR lib. Don't include any servlet apis/impls.

[jordan78gallen]

Thank you so much, its working now. Drinks are on me!!
