Re: [Configuration] Problems reading Chinese text from an XMLConfiguration - Problem solved, thanks

[Matthias Bräuer]

Hello

XML allows you to specify the encoding of the document, otherwise it 
defaults to ISO-8859-1.
[...] change it to ?xml encoding=UTF-8? if that isn't in the xml 
document or the very first item, add it.


The encoding was correctly specified in the XML document. The reason for 
the error was indeed the bug Oliver pointed at:


Note also that in configuration 1.1 final there was a bug that the 
encoding was not always taken into account 
(http://issues.apache.org/bugzilla/show_bug.cgi?id=34204). So you 
might want to check out the newest version from SVN. 


With the current version of Commons Configuration (1.2 dev) the encoding 
is recognized correctly and all Chinese characters remain untouched. 
This works even without specifiying the encoding beforehand (by calling 
setEncoding() ). However, before saving a configuration to another XML 
document the setEncoding() method still has to be called or the file 
will not be stored in the desired UTF-8.


Thanks alot for helping me so quickly.

Best wishes,
Matthias

Re: [Betwixt] Customizing Vector binding with dot betwixt file

[Rodrigo Partearroyo]

Thank for your response Robert, i´ve been on vacations till today. I'll
try your solution.

I´m trying to serialize a Vector of Strings. They are the security-roles

security-roles
security-role rol=rol1 /
security-role rol=rol2 /
security-role rol=rol3 /
security-role rol=rol4 /
/security-roles

but all i can obtain is this:

security-roles
security-role rol=[rol1, rol2, rol3, rol4]/
/security-roles

The bean i'm using is :

public class SecurityRolesBean {
private Vector rolesList;
public SecurityRolesBean (){
rolesList = new Vector();
}
public Vector getRolesList(){
return rolesList;
}
public void setServiceRole(String role){
setRolesList(role);
}
private void setRolesList(String rol){
rolesList.addElement(rol);
}
}

and the dot betwixt file:

?xml version=1.0?
info
element name=security-roles
element name=security-role
attribute name='rol' property='rolesList'/
/element
/element
/info

The question is: How can i put each of the Vector's elements (which are
Strings) in separate xml elements?
 
 
 that 'attribute' tag needs to be an 'element' tag 
 
 ?xml version=1.0?
 info
 element name=security-roles
 element name=security-role
 element name='rol' property='rolesList'/
 /element
 /element
 /info
 
The inverse step (populating the Bean with data read from a xml file) is
done with Digester following this rule:

[...]
pattern value=security-role
set-properties-rule
alias attr-name=rol prop-name=serviceRole /
/set-properties-rule
/pattern
[...]

Due to Digester cannot perform the inverse operation (writting beans to
xml files) i´m trying to move it to Betwixt, but the xml format cannot
change.
 
 
 betwixt should handle this pretty easily. you'll need to add the name of
 the adder to be used to the dot betwixt file 
 
 ?xml version=1.0?
 info
 element name=security-roles
 element name=security-role
 element name='rol' property='rolesList' adder='setServiceRole'/
 /element
 /element
 /info
 
 please take a look at the documentation
 (http://jakarta.apache.org/commons/betwixt) for more details.

Re: Digester: Problem with CallMethodRule

Hi!,

I'm having a little problem with Digester's CallMethodRule: it doesn't 
call the method.


The XML file I try to parse is:

---
configuration
 pages
   page path=/index.htm class=test.TestPage /
   page path=/hello.htm class=test.HelloPage /
 /pages
/configuration
---

The Java code I'm trying to use for parsing the configuration:

---
...
Digester digester = new Digester();
digester.addObjectCreate(configuration, test.Configuration);
digester.addObjectCreate(configuration/pages/page, 
test.PageConfiguration);
digester.addSetProperties(configuration/pages/page, new 
String[]{path, class}, new String[]{path, className});

digester.addCallMethod(configuration/pages/page, freeze);
digester.addSetNext(configuration/pages/page, addPageConfiguration, 
test.PageConfiguration);


Configuration configuration = (Configuration)digester.parse(reader);
---

The problem is that the freeze() method of instantiated 
PageConfiguration objects isn't ever called (which results to that the 
Configuration's addPageConfiguration(PageConfiguration) throws an 
IllegalStateException). How I should fix this? I'm using the version 1.7 
of Digester.
   



Are you sure the problem isn't the *order* that methods get called for
element configuration/pages/page rather than that the freeze method
doesn't get called at all? 


I suggest reading the FAQ entry titled How do I get CallMethodRule to
fire before SetNextRule? here:
 http://wiki.apache.org/jakarta-commons/Digester/FAQ

Simon

AW: [VFS] URLInputStream(jar:file:/Z:/some/where.jar!/META-INF/MANIFEST.MF) ???

[Schuett, Thomas \(EXT\)]

Ups - nearly overseen this answer in the flood of postings :-)

 As a VFS start you can do:
 FileObject fo = 

VFS.getManager().resolveFile(jar:file://Z:/some/where.jar!/META-INF/MAN
IFEST.MF);

 This will do what you want.

Sounds good. However, as I have overseen this reply in the first hand,
I tried by myself, going to use JarFile, and splitting the URI at the
!
by myself. 

But I am sure I can need your approach for more general problems
somewhere in the future.

Thanks for help!

 I'll try to polish the docu :-)

Convert list to map

[Danny Lagrouw]

Hi all,

I need to do a lot of list-to-map conversions, and I'm looking for a way to 
use commons collections for this. I would like to do something like this:

Map map = ListUtils.toMap(list, new SomeTransformerInterface() {
void insertIntoMap(Object object, Map map) {
SpecificObject s = (SpecificObject) object;
map.put(s.getId(), s.getDescription());
}
});

Does something like this exist?

[VFS] fileObject.copyFrom ?

[nice]

Hi all!

And what a great tool VFS is :-) Just having some startup difficulties.

file = fsManager.resolveFile(/path/someDir);
remDir.copyFrom(file, new AllFileSelector());

Ok, the file I want to copy is the directory + content. Somehow it is only the
content of the dir that is copied?? How can i do this?

[VFS] ftp and path problems?

[nice]

Hi again,

I want to define the absolute path for my ftp dir like this:

remDir = fsManager.resolveFile(ftp://me:[EMAIL PROTECTED]/import/home2/me);

That is home2 is probably a mounted dir on the server. This does not seem to 
work.

when using an ftp client the PWD is:
/.automount/idefix/root/export/home2/me

But that too does not work as path.

I have used the:
FileSystemOptions opts = new FileSystemOptions();
FtpFileSystemConfigBuilder.getInstance().setUserDirIsRoot(opts, true);

That works great, but it is not exactly what I want.

any help is welcome :-)

Jens

I am not sure if I understand you fully, but:

You do have a directory e.g.

/home/im/tmp/src
/home/im/tmp/src/file.txt
/home/im/tmp/src/dir/file2.txt

and your remDir is e.g. /home/im/tmp/dest

after the copyFrom you have
/home/im/tmp/dest
/home/im/tmp/dest/file.txt
/home/im/tmp/dest/dir/file2.txt

but you would like to have:
/home/im/tmp/dest/src
/home/im/tmp/dest/src/file.txt
/home/im/tmp/dest/src/dir/file2.txt

correct?


The following two code blocks will solve this:

---cut---
   final FileObject foIN = 
VFS.getManager().resolveFile(/home/im/tmp/src/);
   FileObject foOUT = 
VFS.getManager().resolveFile(/home/im/tmp/dst/);

   FileObject foOUT2 = foOUT.resolveFile(foIN.getName().getBaseName());
   foOUT2.copyFrom(foIN, new AllFileSelector());
---cut---

---cut---
   final FileObject foIN = 
VFS.getManager().resolveFile(/home/im/tmp/src);

   FileObject foOUT = VFS.getManager().resolveFile(/home/im/tmp/dst);
   foOUT.copyFrom(foIN.getParent(), new FileSelector()
   {
   public boolean includeFile(FileSelectInfo fileInfo) throws 
Exception

   {
   return 
foIN.getName().isDescendent(fileInfo.getFile().getName(), 
NameScope.DESCENDENT_OR_SELF);

   }

   public boolean traverseDescendents(FileSelectInfo fileInfo)

   {

It looks like commons-net do have some problems to parse your directory 
listing.

What ftp server do you use?

Could you issue the commands syst and dir in your ftp client and 
post the output here.

If it contains sensitive data you can send the output through personal mail.

Thanks!

Re: [VFS] fileObject.copyFrom ?

Yes you got it, and it works fine thanks a lot.

I guess I assumed that the FileObject returned was that actual src folder, so
it seemed strange that it did not appear when copying it to dest dir.

thanks again

Hi

Cmd: NLST
425: Use PORT or PASV first.
 

Do your ftp client do not have a dir or ls command?

I guess it has something to do with your language setup on the ftp 
server, but I would like to see a directory listing to confirm this.



Do you work on an linux/unix machine? Then we can try to tcpdump the 
communication between you and your ftp server.

[jasper] compiling jsp in osgi context

[Gilles Dodinet]

hi-

i'm trying to execute jsp in an osgi context with no luck as of today. 
i've embedded jetty as an osgi bundle and registered a BundleListener 
which registers installed bundles as webapp if they contain a web 
descriptor file. so far so good. it plays nice with simple html files. 
however i'm encountering troubles when it comes to jsp. generated 
servlets don't compile anything because javax.servlet.* classes are not 
found (please note that the transformation process is successfull).


in the manifest i declare javax.servlet as Import-Package (most prolly 
this seems to cause the issue) and jetty, jasper and related 
dependencies as bundled libs. Also as jasper seems to require an 
urlclassloader i've come up with a (pretty simple) custom urlclassloader 
which delegates all calls to either the target bundle (i.e. the 
installed bundle which wraps the webapp) or the current bundle.  jasper 
classes are succesfully loaded, but not the javax.servlet.* classes. 
googling about this using various criteria gives me in only three 
relevant results :


1/ embedded pagebox whose earlier version (2001) targets the same 
problematic as me. since it is released under lgpl i've tried to use it 
to match my specific needs, however it pretty quick became total hackery 
- 2000 lines src files not maintained since 2001 or so and they 
duplicate lot of services already provided by containers.

2/ a thread on oscar user list with no anwer
3/ a wiki page (entitled 'Tomcat as osgi bundles' and hosted on safehaus 
- with just a listing of bundles i'm unable to find) so i thought i 
could ask here if someone came to a solution to this problem. Has it 
already be done yet ?


below are the relevant manifest entries and webapp registration code. 
the target bundle as no Import-Package and no classes (just the simplest 
hello world). webapp registration [1] assigns the currentThead 
contextClassLoader to the simple delegating classloader discussed above 
- needed to start the webapp, and [2] sets the WebApplicationContext 
ClassLoader to the exact same ClassLoader - which i thought would have 
provided javax.servlet.* classes.


this may not be the best list for this question (should i rather ask on 
jetty or triplesec user lists ?), anyway thanks for any input.
