How to run Jboss under Emma to find code coverage

[Harpreet Singh janda]

We are working on run time code coverage calculation of a web application. For this purpose we are using Emma (a free open source code coverage tool).
To find the coverage of an application the application should run under emma tool like

java -jar emma.jar emmarun -jar Application.jar

this is working for normal jar files but when we are running jboss's run.jar under emma we are getting below exception :

Failed to boot JBoss:
java.lang.ClassCastException: org.jboss.bootstrap.microcontainer.ServerImpl cannot be cast to org.jboss.bootstrap.spi.Server
        at org.jboss.system.server.ServerLoader.createServer(ServerLoader.java:358)
        at org.jboss.system.server.ServerLoader.load(ServerLoader.java:332)
        at org.jboss.Main.boot(Main.java:203)
        at org.jboss.Main$1.run(Main.java:547)
        at java.lang.Thread.run(Thread.java:619)

command we are using is

  java -jar emma.jar emmarun -jar run.jar  

all the dependencies are in the class path and run.jar is running fine if we run it directly from command prompt. We are using linux box.

Please provide your advice.

Hi,

It seems most likely that this is due to using on-the-fly instrumentation approach. Even if you get it to somehow run, your coverage reports will have lot of irrelevant entries for all the classes loaded by jboss including its own libraries and other applications.
I feel you should instead instrument only your specific application jar offline and deploy the instrumented jar.

We have already done this. We have deployed the instrumented war file.
