In the screencast below, I explain the thread status selector and the different threads states in the CPU profiling views.

Appending to redirection files

Thursday, July 09, 2009 | Posted by

install4j has always offered the possibility to redirect stderr and stdout to files. The main purpose of this feature is to analyze uncaught exceptions and to get debug information when something goes wrong in a customer's installation.

The redirection files are created lazily, meaning that as long as there is no output, the file will not be created or replaced. However, once output is detected, the redirection file is created or overwritten. This has been the only option so far and while it is often sufficient to retain the error or debug output of the last run, in some cases you might want to keep the entire output over multiple invocations of the launcher.

In the upcoming install4j 4.2.4, we have added this feature and in the redirection step of the launcher wizard, you can change the classic "Overwrite" behavior to "Append".


The redirection file will still be created lazily, but it will be appended to if it already exists.

Overview of profiling views and profiling settings

We now have a list of screencasts for JProfiler on our web site that is generated from this blog. In order to include the older demos (without audio) into that list, I post them below:
  • Overview of profiling views in JProfilerSee a brief overview of the most important profiling views in JProfiler. Some important functionality is shown to give you an idea on how JProfiler works.
  • Getting started and session settingsSee how easy it is to get started with profiling. Important aspects of the session configuration like profiling settings, triggers and method call recording filters are shown.
Both demos take about 7 minutes and open in a new window. The were recorded for JProfiler 5.0 but are still quite accurate for JProfiler 5.2.
