How to get the entire string with Configuration.getString
Hi,
Configuration (XmlConfiguration) getString returns (^|\\s)#([1-9][0-9]{3
for config.getString([EMAIL PROTECTED]). How can I get the entire
String?
scc task_expression=(^|\\s)#([1-9][0-9]{3,}) /
I use 1.1RC2.

Re: How to get the entire string with Configuration.getString
You have hit a known limitation: The configuration interprets the , as
a property delimiter and inserts two values for this key. For more
details see here:
http://issues.apache.org/bugzilla/show_bug.cgi?id=29716
So config.getString([EMAIL PROTECTED](0)) will return the first
part of the expression and config.getString([EMAIL PROTECTED](1))
the part behind the ,.

File is corrupted after the upload
Hello, We are using the Jakarta Commons File upload mechanism within an application that must upload PDF files to our servers. It happened twice lately to receive PDF files which after the EOF character had many more characters which eventually made the PDF file corrupted (like rubbish) ; by removing these characters we can see that the file is fine and can be recognized as a PDF document. Do you have any hint, whether this may happen during the upload using the Commons File Upload? Thank you in advance for your assistance, Vicky Kontogianni -- This e-mail was checked by the e-Sweeper Service.

[commons-collections]: how to do reverse iteration in TreeBidiMap
Hi list,
maybe a stupid question, or maybe I am missing something, but I cannot sort out
how to
do a reverse iteration over the values of a TreeBidiMap, and couldn't find much
about it
on the web.
I want to retrieve the 10 greatest values from a HashMap, and thought it best
to use a
TreeBidiMap for it.
I have this:
TreeBidiMap bidiMap = new TreeBidiMap(myHashMap);
OrderedBidiMap invMap = bidiMap.inverseOrderedBidiMap(); //creates inversed map
OrderedMapIterator oit = invMap.orderedMapIterator();
while (oit.hasPrevious()) {
Float value = (Float)oit.previous();
.
}
The iterator however seems to be initialized at the first element, so
hasPrevious() is
usually false, and the loop isn't run.
How to initialize the iterator at the last element, so you can start iterating
using
hasPrevious()?
thanks,
Rinke

Re: How to get the entire string with Configuration.getString
Oh, I forgot an important point: you can escape the delimiter using a
backslash. So if your configuration file contains:
scc task_expression=(^|\\s)#([1-9][0-9]{3\,}) /
the entire string should be returned.

Re: [commons-collections]: how to do reverse iteration in TreeBidiMap
Maybe I am confused, but the inverseMap is not ordered in inverse order??
In that case greatest value is first ant lowest is last.

Re: AW: How to get the entire string with Configuration.getString
You can also disable the string splitting by changing the delimiter to a
char unlikely to be found in your configuration:
XMLConfiguration conf = new XMLConfiguration();
conf.setDelimiter('\u');
conf.setFilename(conf.xml);
conf.load();
We will have a cleaner solution when Bug 29716 is fixed

No, that is not the case (sorry for not explaining clear enough).
The inverse map is switching keys and values.
So when the original map has (1, one), the inversed map has (one, 1).
I'm getting the reversed map because I want to order on values. But I also want
the
greatest value first, in stead of last.

Runtime.exec() Utilities?
Is there ANYTHING out there that can help manage executing system commands to batch input, capture output, and generally not make a mess of things on different platforms? I'm pulling my hair out.

Re: [commons-collections]: how to do reverse iteration in TreeBidiMap
I think previous() is not about to get the collection in the reverse
order, it's about to be able to backtrack an iteration. Means, you did
10 next() and you realise you have went one step too far, then you do
previous(). As you said, previous() doesn't start at the end.
I think you have to use something along what matthew proposed.
I would check whether the inversed bidimap keeps the original map
order or whether it orders on the values. If it orders on the values
you would simply do :
OrderedBidiMap inv = bidiMap.inverseOrderedBidiMap();
Iterator it = inv.values().iterator();
while (it.hasNext()) {
// take the 10 firsts.
}
if it is not ordered on the values, then
TreeSet sorted = new TreeSet(yourcomparator); // design a comparator
that would make the greatest the smallest :), or use a collection and
use sort/reverse as Matthew proposed
sorted.addAll( bidiMap.values() );
sorted.iterator(); // then take the 10 firsts.

I used to be quite successful adding ANT tasks to my code for system
management. I.e. this code will copy files and subdirectories from one
directory into another using ANTs copy-task. It will handle recursion as
well as a list of patterns to exclude from copying.
import java.io.File;
import org.apache.tools.ant.Project;
import org.apache.tools.ant.taskdefs.Copy;
import org.apache.tools.ant.types.FileSet;
/**
* Copies ressources from the directory [EMAIL PROTECTED] #getResourceFile()}
* into outputFile.
*
* @param outputFile target directory, must exist and be writeable
* @throws ExportException
*/
private void copyRessourcesTo(File outputFile) throws ExportException {
class CopyTask extends Copy {
/**
* Simple framework class to hold the task itself
*/
public CopyTask() {
Project p = new Project();
p.init();
setProject(p);
setTaskName(copyResources);
setTaskType(copyResources);
}
}
CopyTask ct = new CopyTask();
ct.setTodir(outputFile);
FileSet fs = new FileSet();
fs.setDir(getResourceFile());
fs.setExcludes(*.vm);
ct.addFileset(fs);
ct.execute();
}
ANT gives you a selection of well-tested tasks of all kinds, combinable
and system-independent. Give it a try. HTH,

Re: [commons-collections]: how to do reverse iteration in TreeBidiMap
There is no direct way to iterate over the 10 largest
values. However you can do the following:
TreeBidiMap map;
Object last = map.lastKey();
Object oneBefore = map.previousKey(last);
Object oneBeforeThat = map.previousKey(oneBefore);
Note that these are methods directly on TreeBidiMap.
The alternative is to use a reverse comparator.
BidiMap map;
Collection coll = map.values();
Set reversed = new HashSet(coll,
Collections.reverseOrder());

ANT gives you a selection of well-tested tasks of all kinds, combinable and system-independent. Give it a try. HTH, This looks like it might be perfect: org.apache.tools.ant.taskdefs.Execute Execute(ExecuteStreamHandler streamHandler, ExecuteWatchdog watchdog) However, I don't see a stream handler that can batch input and output. In other words, I have a list of commands I want to send, and I just want all the output retrieved. I was hoping one might be available, so I don't have to write my own in/out/err stream handlers. Do you know of any? I'm going to post a similar question to the ANT list. I will repost the answer back here if a solution is received. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Chain: too damn buggy to be out of sandbox
Well, I don't know why in the heck did jakarta put chain as a main commons project. The thing is too damn buggy. I think it's like esperanto a good idea not very well implemented. The first bug I found was the name of the catalog. Now, read this, cuz this is cool. Only commands that return false are executed. If I return true on a command inside a chain.

Thanks for any input.
I used to be quite successful adding ANT tasks to my code for system

directory into another using ANTs copy-task. It will handle recursion as
well as a list of patterns to exclude from copying.
import java.io.File;
import org.apache.tools.ant.Project;
import org.apache.tools.ant.taskdefs.Copy;
import org.apache.tools.ant.types.FileSet;
/**
* Copies ressources from the directory [EMAIL PROTECTED] #getResourceFile()}
* into outputFile.
*
* @param outputFile target directory, must exist and be writeable
* @throws ExportException
*/
private void copyRessourcesTo(File outputFile) throws ExportException {
class CopyTask extends Copy {
/**
* Simple framework class to hold the task itself
*/
public CopyTask() {
Project p = new Project();
p.init();
setProject(p);
setTaskName(copyResources);
setTaskType(copyResources);
}
}
CopyTask ct = new CopyTask();
ct.setTodir(outputFile);
FileSet fs = new FileSet();
fs.setDir(getResourceFile());
fs.setExcludes(*.vm);
ct.addFileset(fs);

ANT gives you a selection of well-tested tasks of all kinds, combinable

Re: commons logging class level logging
Ok, is there a way of my wrapper class starting up, and automatically detecting all the classes available in every package I specify, and then setting up loggers for each one? I mean an easy way. I could just search through all the files, and convert them to class names without the '/' or '\'. If I could do that, then each class could call log (message, classname). Either that, or I could just have the wrapper class setup a static hashtable of loggers. When a new log request comes in, I can check the classname that's passed into the log method, and use it as lookup into the hashtable of loggers. If it's not there, make it and add it. What do you guys think? Also, again I ask, how does commons logging handle this, considering it is a wrapper around logging implementations?

[Digester] Problem with XML rule definiton.
Dear List: I am having problems with Digester. I am using it to parse the XML returned by Amazon's Web Services. My problem occurs when I create a .jar out of my java program. I am passing the XML rules to DigesterLoader as a stream from the getClass().getResourceAsStream(resource file name) method, and digester likes the rules file. When it actually tries to parse the XML, it chokes on a object creation rule saying that it can't find the class named in the rule. However, when I am running it outside of .jar, it works fine, and the class is included in the .jar (I checked with 7-zip). I have solved the problem by defining rule programmatically, but, for obvious reasons, would like to have them defined in a seperate file. Does anyone have suggestions as to what I might be doing wrong? Sincerely, Silas Snider
[Commons-DBCP] Connections not being closed.
Hi all,
We have had a major problem over the last few weeks with respect to
connections not being closed. The problem started to occur after installing
our software for a new client. I suppose we hadn't tested the software as
well we should have, but we also trust and use a lot of software from ASF.
The DBCP software was correctly keeping track of the numbers such as
minIdle, maxIdle, pool size etc. The problem was the connection, if deemed
to be unusable and therefore not placed back in the pool, was not being
closed. The number of users/connections available on the Database side
slowly became used up and the application unusable. I managed, after some
lengthy logging and debugging and profiling sessions to track down where
this was happening. I have since edited the source code for Commons-DBCP,
rebuilt the distribution and supplied it as part of a patch to our client.
I was just wondering about some things that I hoped somebody might be able
to clear up.
1. Why is Commons-DBCP trying to reproduce the behaviour that a JDBC driver
should carry out? i.e. Having DelegatedStatement and DelegatedResultSet
objects hanging off a DelegatedConnection, which are then closed when the
Connection is closed. The code as it stands at the moment assumes the user
is not going close ResultSet's and Statement's in their own code.
NullPointerException's can be thrown also SQLException's. The implementation
of the JDBC driver we use throws an SQLException if a Statement or ResultSet
have already been closed. Thats OK the exceptions can be ignored, the
Connection can still be used.
Here are the changes I have made to the code:
NOTE: Theses changes fall to pieces when using a StatementPoolFactory.
DelegatedConnection.java
public void close() throws SQLException
{
try {
passivate();
} catch(SQLException sqle) {
throw sqle;
}
finally {
if(_conn != null) {
_conn.close();
}
}
}
protected void passivate() throws SQLException {
log.debug([DelegatingConnection.passivate] Connection ( + _conn +
')');
try {
...
if(set[i] != null) {
set[i].close();
}
...
}
finally {
_closed = true;
}
}

[commons-logging] Problem renaming logfiles
Hi all, I using commons-logging with log4j in my webapp. I'm using a DailyRollingFileAppender and every morning when I start developping I get the following message in my Tomcat console: log4j:ERROR Failed to rename [logfile.txt] to ... I did some investigation using the handle utility from www.sys-internals.com and found that after a redeploy of my webapp, Tomcat is keeping open multiple handles to the same logfile probably causing the rename problem. If I restart Tomcat it has only one handle to logfile as expected until I redeploy again etc. Can someone please tell me what's causing this? I'm using Tomcat 5.0.19 with commons-logging 1.0.3 in its common/lib dir to also use commons-logging for Tomcat. In every class I declare a Log like this: private static Log logger = LogFactory.getLog(MyClass.class); I tried calling LogFactory.releaseAll() from the webapps ContextListener.contextDestroyed() and giving the webapp its own commons-logging.jar but that didn't help.

Re: [Digester] Problem with XML rule definiton.
It sounds like one of two things: 1) in the jar'd configuration something is missing from the classpath 2) in the jar'd configuration you aren't using the same type of classloaders as you are in the non-jar'd configuration (e.g. not just jar vs non-jar, but jar-in-webapp vs unjarred-standalone-app). --- Silas Snider [EMAIL PROTECTED] wrote: Dear List: I am having problems with Digester.
