[net] NullPointerException from nntp.Threader.thread() when all messages in a derived thread are missing.
Using v3.3, I'm getting problems like Exception in thread "main" java.lang.NullPointerException at org.apache.commons.net.nntp.Threader.gatherSubjects(Threader.java:342) at org.apache.commons.net.nntp.Threader.thread(Threader.java:81) at org.apache.commons.net.nntp.Threader.thread(Threader.java:47) when a particular thread branch has no actual messages in it. What happens is that the graph returned by findRootSet() at line 71 will look something like ... ... ... ... And, after pruneEmptyContainers() has had its way with things on line 75, the graph will be ... ... ... ... when it should be ... ... ... ... I.e., ThreadContainer B should be eliminated entirely. As it is, with ThreadContainer B present, but not containing any children or a Threadable, gatherSubjects() chokes. - To unsubscribe, e-mail: user-unsubscr...@commons.apache.org For additional commands, e-mail: user-h...@commons.apache.org
Re: [exec] Using Commons Exec for context-sensitive execution
Hello,
did you try to write actual line endings?
I tested your code and it worked on Windows (cygwin bash) after adding
\n like:
os.write("export MY_VAR=test\n");
os.flush();
os.write("echo myvar:$MY_VAR\n");

I also think the use of the common-executor makes this whole stuff
unecesary complicated. Especially if the alternative is a Java7 with
ProcessBuilder and redirectOutput();

FileItem.fileName differnent with IE 11
Hi, I made a proof of concept for the upload of multiple files with struts 1. It work as expected with FF and chrome but not with IE 11. The FileItem path is differs. With FF the FileItem.fileName is after upload for example "D:\fileuploadtemp\myfile.pdf" which is correct. If I do the same with IE 11, the FileItem.fileName is "C:\Users\my\Downloads\myfile.pdf" Now when FileItem.write(...) is invoked like this: File uploadedFile = new File(TEMP_DIR, fileName); item.write(uploadedFile); with IE 11 an exception is thrown because the resulting path is " D:\fileuploadtemp\C:\Users\my\Downloads\myfile.pdf". This can be handled of course when instantiating the File object, but shouldn't it be same for the browsers? Regards Oliver

[exec] Using Commons Exec for context-sensitive execution
What I'm trying to do is simply run a batch file that does some
preparatory work necessary for the subsequent commands to be executed
successfully (setting environment variables and stuff). To prove this I
put together a sample that uses Commons Exec
publicclassTester{publicstaticvoidmain(String[]args)throwsException{Testertester
=newTester();MyResultHandlerhandler
=tester.newMyResultHandler();CommandLinecommandLine
=CommandLine.parse("bash");PipedOutputStreamps
=newPipedOutputStream();PipedInputStreamis
=newPipedInputStream(ps);BufferedWriteros
=newBufferedWriter(newOutputStreamWriter(ps));Executorexecutor
=newDefaultExecutor();PumpStreamHandlerioh
=newPumpStreamHandler(System.out,System.err,is);executor.setStreamHandler(ioh);ioh.start();executor.execute(commandLine,handler);os.write("export
MY_VAR=test");os.flush();os.write("echo
$MY_VAR");os.flush();os.close();}privateclassMyResultHandlerextendsDefaultExecuteResultHandler{@OverridepublicvoidonProcessComplete(finalintexitValue){super.onProcessComplete(exitValue);System.out.println("\nsuccess");}@OverridepublicvoidonProcessFailed(finalExecuteExceptione){super.onProcessFailed(e);e.printStackTrace();}}}But
that prints empty string instead of the word
"test". Any clues?
