Hi,:
I was trying to run an instrumented web application in jboss and use
saveGlobalProjectData to save data to cobertura.ser, but I got this error:
java.lang.NullPointerException at
net.sourceforge.cobertura.coveragedata.CoverageDataContainer.merge(CoverageDataContainer.java:210)
at
net.sourceforge.cobertura.coveragedata.ProjectData.merge(ProjectData.java:142)
at
net.sourceforge.cobertura.coveragedata.ProjectData.saveGlobalProjectData(ProjectData.java:243)
I checked the source code, but couldn't think of an obvious reason why
this is happening.
Setup:
-- Web application deployed as exploded ear, some of the classes in
WEB-INF/classes are instrumented, not all of them
-- JBoss 4.2.2 running on JDK 5.0
-- saveGlobalProjectData is called by a jsp inside the webapp:
<%
try
{
String className =
"net.sourceforge.cobertura.coveragedata.ProjectData";
String methodName = "saveGlobalProjectData";
Class saveClass = Class.forName(className);
java.lang.reflect.Method saveMethod =
saveClass.getDeclaredMethod(methodName, new Class[0]);
saveMethod.invoke(null,new Object[0]);
out.println("Cobertura data saved.");
}
catch (Throwable t)
{
out.println("Unable to save Cobertura data: " + t);
t.printStackTrace(new java.io.PrintWriter(out));
}
%>
-- cobertura.ser is saved at jboss's bin directory
-- After the web application is started and our test cases are run, we
get "[STDOUT] Cobertura: Loaded information on 43 classes." in console,
so it looks like the ser file is found.
Thanks
Jim
