使用JProfiler分析Maven Web应用程序

Question

I know I can profile my application with JProfiler using ANT target. Is there a way to do the same with maven??
Actually maven allows to run ant targets, using maven-ant plugin, but I'd like to perform such profiling without ANT.

Thanks in advance!

Answer 1

The JVM arguments normally used to enable profiling of the application can be added to the MAVEN_OPTS environment variable. These arguments will also be used for all applications started by Maven.

As an example my MAVEN_OPTS to enable remote debugging on a Jetty instance started by Maven:

set MAVEN_OPTS = "-Xmx512m -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=4000"

Answer 2

It is driven by JVM arguments and some environment entry. See http://resources.ej-technologies.com/jprofiler/help/doc/ for more details at "Requirements for remote profiling" chapter. There is the remote application profiling wizard, and it also tells you what to do exactly. You should do the following:

1.4 JVM LINUX: LD_LIBRARY_PATH environment variable should contain profiler/bin

1.4 JVM Windows: PATH environment variable should contain profiler/bin

1.4 Both: Add -Xrunjprofiler -Xbootclasspath/a:{path to agent.jar} JVM arguments

Above 1.5: -agentpath:[path to jprofilerti library] should be added to JVM arguments
