Problems running dot: exit code=-1, command='dot'
As I used Doxygen to generate source code docuemt, I failed to generate graphs and got this kind of error message:
I spent lots of time to resolve this odd issue, and found out its result from the wrong GraphViz version. I cannot use the latest version. As I tried graphviz-2.12.exe this version, all problems were gone. You can go to here to download this verion: http://www.graphviz.org/pub/graphviz/stable/windows/

Set up a simple way to backup testing server database
1. write an ant build file to generate dump file and copy to remote machine (on a daily basis)
2. create a batch file to execute my build script
3. add this batch file to scheduler service
4. result
[local machine]
[remote machine]

But as I ran my web application, it got this kind of error message (no matter the name of query or the sql statement is corrent):
The root cause is: I forgot to add this enity class declaration into persistence.xml

java.lang.IllegalStateException: ExtensionsFilter not correctly configured. JSF mapping missing. JSF pages not covered.
Error Message
Solution
If you are using servlets 2.4, you cannot do a jsp:forward or request.getDispatcher().forward to any page, because the extensions filter is not executed. Instead you may want to try with a response.sendRedirect(). Therefore, I need to modify to response.sendRedirect("template-client.jsf");

Re: [jasperreports-questions] IS_IGNORE_PAGINATION parameter
Re: [jasperreports-questions] IS_IGNORE_PAGINATION parameter
I had faced the same problem regarding exprting report to pdf in browser but bring blank page.
The root cause is the IS_IGNORE_PAGINATION had been set into FALSE, so it cannot diaplay correctly.
