Aliso, I’m not familiar with the move of the specification to Jakarta - can
there be other implementations of the Spec or is this jar the only possible
source of the API? If there could be other implementations of the Spec,
then you could mark the scope as “provided” - which would mean users would
have to specify the API dependency which could be Jakarta or another
implementation. “Provided” has the same effect as “Optional”.

The Eclipse Public Licenses (EPL 1.0 and EPL 2.0) are both listed as
“Category B” licenses, which means they are fine for binary releases:

https://www.apache.org/legal/resolved.html

Do we need some
> kind of notice for this?


Are the Jakarta jars being shipped in the binary distro or are they just a
dependency in the pom? If they’re in the release distro then yes otherwise
no:

Re: [ jexl3 ]

[Niall Pemberton]

I can see the *ASTFunctionNode *class file in the
*org.apache.commons.jexl3.parser* package of the *commons-jexl3-3.2.1.jar*
file.

Can you provide more details?

   - what specific version of jexl are you using?
   - can you provide the fully qualified name of the *ASTFunctionNode *class
   file that you're missing (i.e. including the package name)
   - can you provide the full class path for your application?
   - can you provide any stack trace for where its failing with the missing
   class?

I think its unlikely the current people working on validator will accept
this as validator used to have javascript validation and its just been
removed from the latest (1.5.0) release:

 Hi,

 We are working on migrating a J2EE application from WAS6.1 to JBoss EAP 5.0. 
 For unmarshalling of some custom XML we make use of commons-beanutils-1.8.3 
 within this application; and in the process, we have defined a custom type 
 converter for one of the XML tags.
 The registration of this converter happens in one EJB module within our EAR, 
 whereas theactual XML parsing occurs in another EJB module within the same 
 EAR.
 The org.apache.commons.beanutils.ContextClassLoaderLocal class ties 'global' 
 variables to a classloader instance in a map to ensure data isolation even if 
 the variable is referenced by multiple components running within a container.
 Here is the relevant code snippet from its get() method:

    ClassLoader contextClassLoader = 
 Thread.currentThread().getContextClassLoader();
    if (contextClassLoader != null)
    {
        Object value = valueByClassLoader.get(contextClassLoader);
        if ((value == null)  
 !valueByClassLoader.containsKey(contextClassLoader))
        {
            value = initialValue();
            valueByClassLoader.put(contextClassLoader, value);
        }
    return value;
    }

 After all that background information, here is the problem:
 During the converter registration process, a BeanUtilsBean instance is 
 maintained in the ContextClassLoaderLocal map against the classloader of the 
 registration EJB module.
 During the parsing process, this map is queried to retreive the same 
 BeanUtilsBean instance, using the classloader of the parsing EJB module as 
 the key. In Websphere Application server, the classloader instance for the 
 registration module and the parser module are both same; the correct 
 BeanUtilsBean instance is retreived and processing proceeds as expected. 
 However, in JBoss EAP 5.0, the two classloader instances are different so 
 that the parser module fails to retreive the value from the map.
 Is this a problem with beanutils' design or an issue with JBoss?

I think you need to register the converter in the module its used in -
i.e. your parsing EJB module

Re: [io] Tailer returning partial lines returned when EOF before newline

 Hi All,

 We are using org.apache.commons.io.input.Tailer to process log files for
 insertion into a database.

 What we are seeing is that occasionally a line fails to process because it
 is incomplete.
 In reviewing the code, it appears that Tailer.readLines delegates to
 java.io.RandomAccessFile.readLine which returns a partial line if EOF is
 reached.

 Shouldn't Tailer be providing a guarantee of complete lines?
 Should we create a bug report for this?

 FYI, we are using 1.6.0_15 on Linux.

Sure

 My log4j configuration creates backup files when the max file size has been

 Does anybody else have similar experience? Is it a usage error on my part?

 BeanUtils (uniquely) has the concept of a MappedPropertyDescriptor

 accessing an underlying Map. In that scenario it does indeed use the
 descriptor to determine the type. However if it has  a Map property
 (i.e. has methods that set/return a Map) then there is no way to
 determine the type. By the time it reaches the line number you quote,
 then its in the later scenario and the type can't be determined -
 since the descriptor type should be a Map.

 Hi Niall,

 thank you for your answer.
 So you're suggesting to replace in our beans code like this:

 public SortedMapString, String getWidth() {
     return widthMap;
 }

 public void setWidth(SortedMapString, String widthMap) {
  this.widthMap= widthMap;
 }

 with:

 public String getWidth(String index) {
        return widthMap.get(index);
 }

 public void setWidth(String index, String width) {
     widthMap.put(index, width);
 }

 Then BeanUtils will use a MappedPropertyDescriptor and map our values 
 correctly?

Yes, but I think you could add those methods (rather than replace) and
it should work.

Niall

You are correct - there is no way to do this.

FileAlterationObserver works by comparing the previous state of a
directory structure with the current state and in order to *match*
files it sorts the contents of each directory on file name to
determine if a file previously existed or has been added or deleted.
As a consequence of that is the behaviour you see - i.e. triggering in
alphabetical order.

There is no straight forward way to do what you want. The file events
would need to be *buffered* in some way and then sorted into time
order before firing the listeners.

Niall

Re: [IO] tailer sample code

[Niall Pemberton]

2010/11/10 Sébastien Roux roux.sebast...@gmail.com:
 I'm not a Java specialist but quite curious about the new tailer classes in
 commons IO 2.0.

 Now what does this mean : TailerListener listener = ...

Its just an abbreviation to show the line is not complete.

You have to create your own TailerListener implementation which does
whatever you want with the lines added to the file. So for example you
could do something like the following:

/**
 * TailerListener implementation.
 */
public class ShowLinesListener extends TailerListenerAdapter {
@Override
public void handle(String line) {
System.out.println(line);
}
}

Then create the Tailer with your implementation:

TailerListener listener = new ShowLinesListener();
Tailer tailer = Tailer.create(file, listener, delay);

http://commons.apache.org/io/api-release/org/apache/commons/io/input/Tailer.html

 I mean what I am supposed to put after the equal? Would you have a quick
 example regarding basic file tailing implementation?

Re: [io] is 2.0 on Maven?

The reason the existing groupId was used was because it was a compatible
release and so far in Commons we have not collectively or individually
decided to relocate artifacts in that scenario.

Its probably a discussion we should have over on d...@. Although it will
create issues for users relocating all our artifacts (and adding redirection
poms) - it is something that can be resolved by a user (AFAIK they just have
to remove old artifacts from the local repo). I'm starting to think we
should just bite the bullet and do it.

 DOH!  Well, that stinks.  I guess we do need to have a discussion on
 how we plan to play nice with respect to all of this
 version/artifact/group management.  I think the plan of keeping the
 artifactId and the package names in sync is a good idea.  But, we need
 to be careful about this whole new groupId thing.  Should we fire up
 a discussion thread on d...@?

We could, but I would suggest a slightly different approach. This has
been discussed in the past and from memory there is more than one
approach that could be taken. The problem with starting a discussion
is that the different points people make about how and the pros and
cons get fragmented among a large thread. I think the best thing would
be to start a Wiki page - that way we could collect all the options
and pros/cons in one place. Once we've done that then its likely to
make any discussion much easier and less contentious. I'm very busy
for the next week, so I'm happy to take part in that - but not just at
the moment.

Re: [validator] Possible to configure multiple error messages for a single validator?

[Niall Pemberton]

On Wed, Sep 29, 2010 at 7:09 PM, Christopher Schultz
ch...@christopherschultz.net wrote:
 -BEGIN PGP SIGNED MESSAGE-
 Hash: SHA1

 All,

 I've been happily using commons-validator 1.3.1 with Struts 1.3 for some
 years, now, and I've recently developed my own custom validator that
 checks for XHTML syntactic validity. Technically, it checks for XHTML
 validity only when the input looks like this: html/html:
 everything else validates successfully with no actual XHTML syntax check.

 Recently, it became clear that users were sometimes forgetting the
 /html at the end of the input. This caused two problems: first, the
 input wasn't being validated as XHTML, and second, when the data was
 then displayed in a web page, it was escaped instead of being rendered
 as actual HTML.

 My first instinct was to add a mask validator that checked for an
 appropriate pattern (that is, html up front with no trailing
 /html). I implemented that and it works quite well. Then, it
 occurred to me that I might want some other pattern for some reason for
 those fields, and that the correct place for that check ought to be in
 the XHTML validator itself.

 So I started moving the check described above into my custom validator.
 Everything was fine until I had to render the error message. Since I'm
 doing essentially two checks (one for html and matching /html, and a
 second for actually checking the XHTML syntax), I need two distinct
 error messages. The configuration for a validator only allows one single
 msg attribute as shown in my configuration below:

      validator name=possibleXhtml
            classname=PossibleXhtmlValidator
               method=validatePossibleXhtml
         methodParams=java.lang.Object,
                       org.apache.commons.validator.ValidatorAction,
                       org.apache.commons.validator.Field,
                       org.apache.struts.action.ActionMessages,
                       org.apache.commons.validator.Validator,
                       javax.servlet.http.HttpServletRequest
              depends=
                  msg=errors.xhtml /

 I could simply hard-code the error message key into the validator, but
 that seems less maintainable than I'd like it to be. Is it possible to
 provide more than one error message key to a validator like this?

 Other options for me include creating a custom validator that does
 nothing but check for the html.../html that won't interfere with,
 say, the mask validator.

 It still seems to me that my goal ought to be a single validator that is
 basically self-contained, rather than having two validators that
 essentially /must/ be used together.

 Does anyone have any suggestions?

Its been a long time since I worked with Stuts  Validator, but take a
look at the *standard* validators defined in struts:

http://svn.apache.org/viewvc/struts/struts1/trunk/core/src/main/java/org/apache/struts/validator/FieldChecks.java?view=markup

Its the validation implementation that actually adds the messages to
the Struts ActionMessages object - usually by calling

   Resources.getActionMessage(validator, request, va, field))

http://svn.apache.org/viewvc/struts/struts1/trunk/core/src/main/java/org/apache/struts/validator/Resources.java?view=markup

So you need to create your own custom getActionMessage() impl - you
could use the msg returned from the field or validator and use that
as a prefix and append a different suffix for each error.

Alternatively you could define two separate validators - one for each condition.

Niall

 Hi all, I'm trying to do something really simple but I can't seem to figure

 }

The way to do this in BeanUtils is to get rid of your overloaded
setter for ClassTypeB and register a converter with Beanutils.
Something like...

ClassTypeAConverter converter = new ClassTypeAConverter();
ConvertUtils.register(converter,  ClassTypeA.class);

That way when you use BeanUtils.setProperty() it will call the
converter to convert the ClassTypeB to ClassTypeA.

Niall

 If I invoke the setter by passing an instance of ClassTypeA, it works without 
 a problem:
 BeanUtils.setProperty(myBeanInst, myProperty, instanceOfClassTypeA);


 However if I invoke the setter by passing an instance of ClassTypeB, I get an 
 exception and the setter is never actually called:
 BeanUtils.setProperty(myBeanInst, myProperty, instanceOfClassTypeB);
 java.lang.IllegalArgumentException: Cannot invoke.. la la la - argument type 
 mismatch -

 I can't believe it is not possible to do that, I'm sure I'm just missing 
 something. Any help will be greatly appreciated.

 Many thanks

Re: [beanutils] beanutils library cannot invoke the correct accessor

Well you're wrong about this - if you go an read section 8.3 Design
Patterns for Properties of the Java Bean Specification you will see
it specified a *pair (i.e. getter  setter) of accessor methods for
properties.

 without a problem:
 BeanUtils.setProperty(myBeanInst, myProperty, instanceOfClassTypeA);


 However if I invoke the setter by passing an instance of ClassTypeB, I get 
 an exception and the setter is never actually called:
 BeanUtils.setProperty(myBeanInst, myProperty, instanceOfClassTypeB);
 java.lang.IllegalArgumentException: Cannot invoke.. la la la - argument

 I can't believe it is not possible to do that, I'm sure I'm just missing 
 something. Any help will be greatly appreciated.

Re: [beanutils] beanutils library cannot invoke the correct accessor

 Hi James, thanks for keeping up with my questions.

 So, you mean end up with something like this: ?

 public class MyBean {
       private ClassTypeA myProperty;
       private ClassTypeB myPropertyAsB;
       private ClassTypeC myPropertyAsC;
       private ClassTypeD myPropertyAsD;

       public void setMyProperty(ClassTypeA anObj) {
               this.myProperty = anObj;
       }
       public void setMyPropertyAsB(ClassTypeB anObj) {
               this.myProperty = Converter.convertBtoA(anObj);
       }
        .
        .
        .
 }

 Isn't this hacky as hell, just to compensate for beanutils' lack of basic 
 functionality (i.e., method overloading)? That looks really messy in my 
 opinion, imagine doing that for a number of properties in a few beans. I 
 honestly don't understand why this functionality is missing from beanutils. 
 Anyhow, even if I wanted to do that, I could not in my use case. It's a very 
 dynamic environment where property names are computed automatically based on 
 mappings or field names in a DB. So I couldn't have multiple 'technical' 
 property names for the same 'logical' property without butchering an 
 otherwise very elegant design. I'd rather enhance the beanutils library 
 instead. So the question still stands, how would I go about it?

Hacky as hell is you overloading the accessor methods and will cause
you problems when using your java beans with any technology that
relies on the JavaBean specification - not just BeanUtils. I would
really recommend you avoid doing this.

Niall


 Henri, thanks a lot for the tip about JEXL2, I will look into it and see if 
 it's less work to replace beanutils with that library, instead of enhancing 
 the beanutils library.

 Folks!

 What Henri says is completely right.

 The project has been abandoned by me as I lost faith in one of its
 goal - ACID properties (especially atomicity) on any file system. From
 my (and others) point of view it can not be achieved by *any*
 implementation. So if you are asking whether there is another
 implementation that is more suitable, my answer is there can't be
 any.

Apologies I'm not familiar with transaction - but does this apply to
the released versions (1.0 to 1.2) - are they flawed or is this
something that only applies to the unreleased 2.0 code base?

Niall

 Certain parts of the 2.0 code are quite reasonable, though, especially
 the locking and deadlock detection part. That's why I have not been
 determined what to do with the project. Certainly 2.0 is better than
 1.x by any means, but I still think it should not be released as its
 promises can not be kept.


 Any thoughts?

 2010/3/5 Henri Yandell flame...@gmail.com:
 The current version is 1.2 (released in 2007).

 1.3-SNAPSHOT is then the subsequent version in development, but it
 looks as though it was quickly renamed to 2.0.

 2.0 currently has 6 of 9 issues resolved, the most recent being
 reported and applied in Sept 2009, and 2 of the open issues were
 opened a month ago.

 So I wouldn't call it dead - there just hasn't been much to do. Your
 email does raise the question of whether 2.0 should be released or
 not. I've cc'd Oliver who has been doing most of the work.

The createArrayOf() method was added in JDBC 4 / JDK 1.6:

The current release of DBCP doesn't currently support JDBC 4 which is

 Hi,

 How can I set a 'null' on Integer property (or any other wrappers like
 Double, Long, Character etc) via BeanUtils.setProperty? If its not
 possible this way than is there any other way using apache commons ?

 If you don't want conversion then you can use
 org.apache.commons.beanutils.PropertyUtils.setProperty() method - but the
 value object has to be the correct type (or null).

 For PropertyUtils see: http://tinyurl.com/yf9f6wk

 BeanUtils adds conversion to PropertyUtils  - it tries to convert the value
 you specified to the correct type of the the bean's property.
 These converters have behaviour defined on how to handle null values and
 operate in two modes:
  - throw an exception
  - use a default value

 The default set of converters which are registered with BeanUtils have a
 default value specified - so for example the converter registered for
 Integer types has a default value of zero. This is why you can't set a
 null value at the moment. If you want null values to be set then you need
 to register converter implementations for those types with a default value
 of null. So for example you would do something like...

  ConvertUtils.register(new IntegerConverter(null), Integer.class);
  ConvertUtils.register(new DoubleConverter(null), Double.class);

 (Note: the null value in the constructors is the default value)

 For ConvertUtils see: http://tinyurl.com/ydhq85s For converters see:

 page http://commons.apache.org/beanutils/ it's mentioned
 that commons-beanutils.jar has an optional dependency on Collections. What
 does optional mean? Here

You need Commons Collections if you use any of the following classes:
BeanMap
BeanPredicate
BeanPropertyValueChangeClosure
BeanPropertyValueEqualsPredicate
BeanToPropertyValueTransformer

 http://commons.apache.org/beanutils/dependencies.html it additionally says
 Logging is a dependency. And then, here is stated that both Collections and
 Logging packages are a _requirement_:
 http://commons.apache.org/beanutils/apidocs/org/apache/commons/beanutils/package-summary.html#overview.dependencies

That page is out of date wrt to Commons Collections - patches welcome

 Still, I've done some (very basic) successful experiments with BeanUtils
 with neither Collections nor Logging on the Classpath. What's the deal?

I'm surprised that you didn't have any issues without commons logging
since some of the core features of beanutils use them.

Niall


 Best Regards,
 Joonas

Re: NPE from DBCP connection pool

 I've got a BasicDataSource and I'm trying to run a relatively simple query.
 Not sure where the NPE could be coming from.  The SQL statement in question
 is extremely simple, a single-column SELECT with a single JOIN and a WHERE
 clause.  It works fine in a SQL browser.  The query is Oracle 11g, but I'm
 pretty sure that doesn't matter since it doesn't look like the query is
 getting that far.

The sql statement you're passing in has got to be null since the
normalizeSQL() method only does sql.trim(). Also it would make
investigation issues much easier if you specify the version of DBCP
you are using.

Niall

 Note that other queries still work, just this one in particular.  So it's
 not an issue with connections closing or something like that.  Any ideas?

 Thanks.

 That seems to complicate matters IMO. If we care about having v1 and v2 
 co-exist in a Java 5 application, then the v2 packages must to be renamed. So 
 if that is what we want, let us just bite the bullet and rename now.

I don't really get why you say it complicates matters as being
backwards compatible means that you don't need v1  v2 to co-exist.

 Not to bug you Gary, but any update on this?

 I'm really looking for CODEC-69 (Streaming Base64).  Are the current

 current version is 1.4-SNAPSHOT but I only see downloads for 1.3.  The

  Hi,
 
  I'm mostly happy with the state of the CODEC in the repository.
  Base64 can be properly streamed when using the repository version, and
  I believe it's at least 33% faster than any of these:
 
  1. http://iharder.sourceforge.net/base64/   (2 times faster)
  2. sun.misc.BASE64Decoder   (2 times faster)
  3. openssl enc -base64 -d   (about 33% faster?)
 
  Obviously I wish the patch I submitted for CODEC-75 would be applied
  (I'm privately forking for my own needs).

 an issue for this issue in our old JIRA issue tracker?

Looks to me like the existing Sanselan JIRA issue tracker has just
been moved under commons. So yes nothing changes with creating issues
- you can either point people to the same JIRA url here:

http://issues.apache.org/jira/browse/SANSELAN

or theres a page on the Sanselan site which provides guidance and
useful urls for the Sanselan JIRA instance:

 Hi there everyone,

 I'm trying to use Sanselan to write XMP data to an image. The problem is
 that in doing so, it appears to corrupt the other IPTC data such that it is
 not visible in all circumstances (i.e. Windows Explorer doesn't display it).
 It's there in the file, just not in the expected location perhaps.

 Is there a way to handle this such that the added XMP doesn't change the
 content of the rest of the file? I tried re-writing the IPTC metadata but to
 no avail. Perhaps I haven't discovered the magic sequence of events that
 need to be followed.

 Any pointers would be much appreciated!

Either here or on the dev list.

 First of all the nightly builds link on the download page of the Net

There are no nightlies being built  now.

 The page containing the link is:
 http://commons.apache.org/net/download.html

 Not working link leads to the following URL:

 I could find a nightly snapshot link from the main page
 http://commons.apache.org/ . The latest nightly snapshot of the Net
 component seems to be from 2007.
 I assume that nightly snapshots of the Net component are not provided
 anymore since the latest release in 2008 is more fresh than the last
 nightly snapshot I could find? Please correct me if I'm wrong and
 there is another location where to find the nightly snapshots.

 My last concern this time is the MDTM command. It throws an exception
 and it seems that there _commands array in the FTPCommand class is
 lacking the MDTM command, but since I have only the latest release
 build at hand I cannot verify if this has been already corrected or if
 a bug report should be filed?

You can look at the current source,

http://commons.apache.org/net/source-repository.html

...and for Net 2.x thats here
http://svn.apache.org/repos/asf/commons/proper/net/branches/NET_2_0/src/main/java/org/apache/commons/net/ftp/FTPCommand.java

Looks like MDTM has since been added:

 Morph is not generics-enabled; it can handle most of your basic non-generic

 can throw at it if you want to implement its API here and there for custom 
 transformations, and while I am 100% sure it can handle [n] index notation I 
 am about 90% sure it also handles indices as property names as you have 
 described (.n)--if not, that is pluggable.  But this isn't the Morph list 
 and, as you said, you made a management decision not to pursue it.  As a 
 Morph team member I will take your documentation didn't look very helpful

 response I'm afraid. Well ok i might let you off for anything involving
 hospitalisation, death or taxes ;)

Yes all of those I'm afraid!

 Is there any kind of roadmap for beanutils to bring in decent locale
 handling and more refined converter mapping? (mapping a converter to a
 property, not just a complete class)

None that I know of.

 I like beanutils - some people say it's got a (inter-)face only a mother

 Dear All,

 I am enjoying using Commons BeanUtils with all its converters and

 I was wondering if it was possible to retain this goodness whilst changing

 'setFoo(x)', I'd like to use 'foo()' and 'foo_$eq(x)' which is the native
 Scala naming convention.

BeanUtils uses Introspector[1] at its heart[2] to discover the
properties of a bean - which is based on the java bean spec and tied
to the get/set naming convention for methods. So if you want to change
this behaviour you would need to start by overriding the
getPropertyDescriptors() method in PropertyUtilsBean

 working perfectly, until I try and introduce duplicate key entries (i.e. a
 node can have 1 children of the same name).

 My example heirarchy I wish to build is this...

 /
 /car='Ferrari'
 /car='Porsche'
 /car=Lamborghini'


 In xml it might look like...

 root
carFerrari/car
carPorsche/car
carLamborghini/car
 /root


 Anyway, to cut to the chase. I have multiple 'car' property entries and I am
 trying to run the follwing code:

 LazyDynaBean lazyDynaBean = new LazyDynaBean();
 JXPathContext jxPathContext = JXPathContext.newContext(lazyDynaBean);
 lazyDynaBean.set(car,0, Ferrari);
 lazyDynaBean.set(car,1, Porsche);
 lazyDynaBean.set(car,2, Lamborghini);
 Iterator i = jxPathContext.iteratePointers(car);
 while(i.hasNext()){
 System.out.println(Got pointer: +i.next().toString());
 }


 The error is:

 How am I supposed to populate the DynaBean so that it can contain more than

I would have expected the lazy DynaBean to contain a list of Strings -
I would check if it does. If it does then the issue is in JXPath.

 Also, I would prefer not to have to specify the index 0,1,2 if that is at

 Hi,

 I am very new to the beanutils.
 I am trying to set value to an array list using indexed properties.

 It is throwing the following error
 Exception in thread main java.lang.
 IndexOutOfBoundsException: Index: 0, Size: 0

at 
 org.apache.commons.beanutils.PropertyUtilsBean.setIndexedProperty(PropertyUtilsBean.java:1711)

 Here is my  code

BeanUtils doesn't automatically grow arrays/Lists (except for
LazyDynaBean) - so while you can use the indexed setter to set an
indexed property the List needs to have elements that size already,
otherwise you see exactly the error you're getting. So you have a
number of ways you can resolve this:

1) Ensure that your List is always large enough - so if for example
you know that there will never been more than five addresses, then
initialize the list with five empty/null elements [not that I'm
recommending this - hacky]

2) Provide indexed getters/setters in your object (BeanUtils will use
if available these rather than the List getters/setters) and implement
lazy list growth. So in your address example something like:

https://java.sun.com/docs/books/tutorial/javabeans/properties/indexed.html

public Address getAddr(int idx) {
while (idx = addr.size()) {
addr.add(new Address()); //dynamically grow list to accomodate
}
return addr.get(idx);
}

public void setAddr(int idx, Address element) {
while (idx = addr.size()) {
addr.add(new Address()); //dynamically grow list to accomodate
}
this.addr.set(idx, element);
}

3) Use a lazy list to hold your addresses - for example:
http://commons.apache.org/collections/api-release/org/apache/commons/collections/list/LazyList.html

4) Use a LazyDynaBean, which supports lazy list/array growth out of the box

 I have copied the sample code for the two beans and a test main class below. 
 Could anybody else verify that this is occurring too? I am using 
 beanutils-1.8.0.

You have a choice of two flavours for copying properties in BeanUtils:
1) Usng PropertyUtils copyProperties() method[1] - this just copies
any properties unchanged
2) Using BeanUtils  copyProperties() method[2] - copies AND converts
properties - so for example, if theres a property called foo of type
String in the source and a property called foo of type Integer in
the destination then it tries to convert the String to an Integer
using the Converter registered for Integers.

If you don't need conversion then you can switch to using
PropertyUtils. If however you have some conversion needs, but you
don't want it to throw an exception when a value is null (which is
the default behaviour) - then you can configure a converter for Date
which has a default value. So for example, if you wanted a default of
null for Dates, then something like the following:

java.util.Date defaultValue = null;
DateConverter converter = new DateConverter(defaultValue);
ConvertUtils.register(converter, java.util.Date.class);

Then when you call BeanUtils.copyProperties() it should no longer
throw an exception.

 Hi @all,

 as it seems, the PropertyUtils.copyProperties() as well as
 BeanUtils.copyProperties() only do a copy on class-level.
 As I would like to reuse my copy-methods for an inherited
 class-structure I would like to ask if there is also a chance to do a
 full-object copy for inherited classes for all properties.

 ==
 Example:

 public class Class1 {
private String attribute1;
 }

 public class Class2  extends Class1 {
private String attribute2;
 }

 public class Business {

public static copy(Class1 source, Class1 dest) {
PropertyUtils.copyProperties(source, dest)
}
 }

 If I call Business.copy() with 2 instances of Class1, attribute1 is
 perfectly copied. But if I call the same method with 2 instances of
 Class2, only attribute1 is copied although I would also like to copy
 attribute2 as well. Any chance to do that?

It does do this - but looks like you have the parameters the wrong way
round, try

   PropertyUtils.copyProperties(dest, source)

 Furthermore I realized that enumerations are not copied, too. Is there a
 chance to copy the bean-instance including enumerations?

BeanUtils doesn't support JDK 1.5 features and it doesn't look very
likely it will do so since its pretty much in maintenance mode.

Re: [Chain] Parametizing commands?

[Niall Pemberton]

On Fri, Sep 5, 2008 at 5:49 PM,  [EMAIL PROTECTED] wrote:

 I'm looking for a way to decouple the context keys used in a command from
 the actual context keys used at runtime. Here's an example:

 Here's a really simple command  that just concatenates two strings from the
 context - the keys are A and B and the concatenated output goes in C:

 public class Concat implements Command
 {
@Override
public boolean execute(Context context) throws Exception
{
context.put(C, (String) context.get(A) + (String)
 context.get(B));
return false;
}
 }

 Let's say I need to create a chain that uses this command, but the other
 commands leading up to this one leave the two strings that need to be
 joined the context under the keys FIRST_NAME and LAST_NAME, and the result
 is expected to be in FULL_NAME for the next step in processing. So now I
 have to create two more commands: one to move FIRST_NAME to A and LAST_NAME
 to B, so that the strings are in the right places for my Concat command,
 and then another to follow that moves C to LAST_NAME.

 That's not very nice - I now have three commands to do the job of one. If I
 need to use Concat somewhere else but using different keys again (combining
 DIRECTORY and FILE to create PATH, say) I have to create yet more commands
 just to move things around so that I can re-use the command that does the
 actual work. And in fact in the application I've been developing something
 like a third of the commands in the app are just to do this kind of
 data-shuffling, and I have command chains that are twice as long as they
 really should be.

 What I'd like to be able to do is provide some kind of mapping from the
 label keys used by my command code, to the real keys that get used at
 runtime. As an example, I might want to represent my chain something like
 this in XML:

  command name=Concat
map label=A to=FIRST_NAME /
map label=B to=LAST_NAME /
map label=C to=FULL_NAME /
  /command
  command name=Concat
map label=A to=DIRECTORY /
map label=B to=FILE /
map label=C to=PATH /
  /command

 I could do this myself *if* there was a way to parametize individual
 command references in a chain something like this, but as far as I can tell
 there is no such option in Chain as it is right now.

The sample webapp(s) has an example of exactly this - theres an
example forward command where the actual forward is specified as a
property:

http://svn.apache.org/repos/asf/commons/proper/chain/trunk/apps/example1/src/main/java/org/apache/commons/chain/apps/example/ForwardCommand.java

Then in the chain config you specify the fowards property:

http://svn.apache.org/repos/asf/commons/proper/chain/trunk/apps/example1/src/main/webapp/WEB-INF/chain-config.xml

Niall

 It strikes me, having used Chain for a while, that I am probably not the
 only one to have come across the general problem of having fixed keys in
 Commands referring to movable data in Contexts. What I've described here
 is a potential solution but I don't think it'll work because Chain doesn't
 support being able to attach parameter sets to Command references. Is there
 another solution out there?

You need to develop a custom routine since that method (and other

 Are there plans in place to update the commons apache components to build
 with JDK 1.5 instead?

Its being done on a component-bycomponent basis. The following list
may not be complete, but this is the state-of-play that I know of:

1) Collections - has had a JDK 1.5 branch for quite some time, not
very active atm
http://svn.apache.org/repos/asf/commons/proper/collections/branches/collections_jdk5_branch/

2) Configuration - Version 2.0 branch requires JDK 1.5:
http://svn.apache.org/repos/asf/commons/proper/configuration/branches/configuration2_experimental/

3) IO - last release (1.4) was JDK 1.4 compatible, but the current
trunk (and the next release, probably 2.0) now requires JDK 1.5

4) Lang - discussed recently on the dev list:
http://markmail.org/message/k36vrkgupiewg3qx

5) Math - Version 2.0 branch requires JDK 1.5:
http://svn.apache.org/repos/asf/commons/proper/math/branches/MATH_2_0/

6) Net - Version 2.0 branch requires JDK 1.5:
http://svn.apache.org/repos/asf/commons/proper/net/branches/NET_2_0/

7) SCXML - J6 branch requires JDK 1.6

Yes it should return true. Can you use a debugger to find out which

 Does common codec ver 1.1 contain symmetric cryptographic algorithms

There is documentation on this for the whole ASF here:

Theres an Apache Commons section - and as Codec is not listed there

Well it depends on the getters/setters you have defined. If you have

  public Map getMyMap()
  public void setMyMap(Map)
  public Long getMyMap(String)
  public void setMyMap(String, Long)

Then it should return a Long as the type.

  Note that getPropertyType() with a property name of simply myMap also
  returns java.util.Map, which is what I would expect.

I have a modified lazy DynaBean implementation that can track

Re: [BEANUTILS] LocaleConvertUtilsBean convert method with null locale

[Niall Pemberton]

On Fri, Feb 15, 2008 at 1:39 PM, Lucian Chirita [EMAIL PROTECTED] wrote:
 Is the LocaleConvertUtilsBean.convert(String value, Class clazz, Locale
  locale, String pattern) method supposed to accept null Locale arguments?

  This generally works, as the locale is used to resolve a converter, and
  the lookup(Locale locale) method checks whether the argument is null and
  uses the default locale in this case.

  However, when debug statements are enabled for LocaleConvertUtilsBean,
  the convert methods fails with NullPointerException on null Locale as
  the debug statement does locale.toString().

  Could this inconsistency be considered a bug?

Yes please file a bug report in JIRA:

Re: Commons validator error

[Niall Pemberton]

On Nov 9, 2007 4:47 PM, Nuno Martins [EMAIL PROTECTED] wrote:
 Hi all,

 I'm developing a commons-validator (with struts) standalone application.

Not sure what you mean by standalone and with Struts. Are you
using the standard built-in Struts validation? From the error below I
guess not - I can only see one way this could have happened:

1) A null reference was passed to the validateMask() method where it
expected an ActionMessages object.
2) The null  ActionMessages caused a NullPointerException to be
thrown on line 235 of FieldChecks in the validateMask() method (where
it tries to add a message to the ActionMessages object).
3) That NullPointerException was caught by the try/catch block in the
validateMask() method so it called the processFailure() method.
4) The processFailure() method logged the message mask validation
failed for property xpto: java.lang.NullPointerException
5) The processFailure() threw another NullPointerException on line
1323 when it tried to add a message to ActionMessages
6) ValidatorAction caught the 2nd NullPointerException and logged the
message Unhandled exception thrown during validation: null  + stack
trace

Perhaps I'm wrong, but this is the only explanation I can see. If I am
right then it looks like you are not using the standard build-in
Struts validation and the problem is you haven't configured the
Validator instance you're using with an ActionMessages object.
Fixing that issue should resolve the problem - something like:

validator.setParameter(ACTION_MESSAGES_PARAM, errors);

Best place to look on initializing Validator is in the validate()
method of ValidatorForm[1] and initValidator() method of Resources[2]
