Re: commons-daemon with JVM included in Fedora?

[Bernard]

Jean-Frederic

Your suggested solution works without problems so far.

In location.c, I added

"/usr/lib/libgcj.so.6",  /* gij (GNU libgcj) (Red Hat
4.0.0-8) */

It appears that Red Hat Fedora 4 does not set JAVA_HOME, and the
location of libgcj.so.6 is not in the same directory as the other java
executables so I could not use that.

Who creates a new version if any and when?


Would you be able to explain to me the syntax of the first line in the
file jakarta-commons-daemon.spec?

%define native  %{?_with_native:1}%{!?_with_native:0}

Where can I learn about this syntax?

Where is the syntax of the "define" keyword documented?

What does  "{?" mean?

Is this bash? I looked up "man bash" but there is nothing like "{?"

What does  "{!?" mean?

What does the whole command 
"%{?_with_native:1}%{!?_with_native:0}"
mean?

Many thanks

Bernard

Re: commons-daemon with JVM included in Fedora?

[Bernard]

Hi Bill,

How can I compile jsvc?

I have not done C development in my life.

I installed the source package
jakarta-commons-daemon-1.0.1-1jpp.src.rpm.
I modified the C source file as suggested.
Then I did "rpmbuild ba jakarta-commons-daemon.spec"
it did not appear to compile the C source. Why?

Would you have any ideas?

Bernard

Re: commons-daemon with JVM included in Fedora?

[Bernard]

Hi Bill

Thanks for your reply.

I think the JVM that comes with fedora 4 is a bit different.
# eche $JAVA_HOME returns nothing

From the jsvc output below I understand that jsvc has a problem
finding the JVM.
However it appears to be ok otherwise because I can run tomcat without
problems.

I used yum to get my jsvc packages:

# rpm -qa | grep jakarta-commons-daemon
jakarta-commons-daemon-1.0.1-1jpp
jakarta-commons-daemon-jsvc-1.0.1-1jpp

These have worked for me on RedHat 9 with Sun's JVM.

On Fedora 4:

# java -version
java version "1.4.2"
gij (GNU libgcj) version 4.0.0 20050519 (Red Hat 4.0.0-8)

I would be grateful for any ideas.

Thanks

Bernard

commons-daemon with JVM included in Fedora?

[Bernard]

Hi,

jakarta-commons-daemon-jsvc-1.0.1-1jpp

when installed on Fedora 4 Linux, does not appear to like the
installed JVM:

gij (GNU libgcj) version 4.0.0 20050519 (Red Hat 4.0.0-8)


Can anyone suggest a way to get this working?

I would like to use the installed JVM instead of Sun's.

Many thanks

Re: Tomcat 5 shutdown issue with jsvc commons daemon

[Bernard]

Thanks Wolfgang!

Still problems.

I downloaded from
http://cvs.apache.org/builds/jakarta-commons/nightly/commons-daemon/
the latest file:
commons-daemon-20050316.zip

autoconf worked fine.
./configure worked fine.
make failed with many errors.

How to fix this? Is it worth it? When is the next version coming out?

The errors are below.
I cross-posted to the commons-dev list because I used a nightly build.

Many thanks,

Bernard

jsvc on Linux: multiple instances possible, why -pidfile?

[Bernard]

Hi,


I created multiple jsvc instances that did not die.
That happens with the adapted Tomcat5.sh supplied with the Tomcat 5.5
distribution.

That's a problem.

I would appreciate some help in understanding the logic of the pid
file.

This is my view of things; please correct me and help me if I am
wrong:

If, as it is presently the case, jsvc creates a pid file, then it must
not be possible for jsvc to launch a second copy of a service.

jsvc should however be able to briefly run only itself as multiple
instances - it must be allowed to do so in order to check the pid
file. It would not be reliable to pass this responsibility to the OS.

So any jsvc copy on top of the first should exit with an error
condition, and it should not attempt to start the jvm with the server.

If jsvc is NOT designed to block multiple service instances, then it
must not write the PID file. In that case it would be the
responsibility of the script to write the pid file and block multiple
service instances.

What to do?

Many thanks,

Bernard

RE: DBCP

I think the first conn.close is unneeded, because the finally block is
always executed.

Calling BasicDataSource.close() will only close the connections still in the
pool -- not the ones that have been checked out.  It is designed to be
called only when your app is ready to shut down.

For normal usage, the best approach is something like this:

DataSource ds = ... get your data source reference;
Connection conn = null;
try {
conn = ds.getConnection();
... use the connection as needed ...
conn.close(); // Returns this connection to the pool
} catch (SQLException e) {
... deal with any exception ...
} finally {
if (conn != null) {
try {
conn.close();
} catch (SQLException e) {
...
}
}
}

That way, you're always returning the connection to the pool, even if an
exception occurs while you're using it.

BTW, your MySQL admin will show active connections for all the entries in
the pool, as well as those that have been checked out and are in use.

Subject: [OT] Test generation


A quick question for the collective brains trust.

I have been looking into test (and code) generation and have come to a
unexpected results.
1) JUnitDoclet appears to be the only (reasonable) opensource product around
2) commerical equiv are incredibly expensive
3) JUnitDoclet seems extremely like a decent tool, up to a point.  It seems
extremely limited and not terribly configurable (at least easily).  And
support for standard tests or standard layouts for common code structures
does not seem easy/available

This brings me to my questions:
1) Are the statements above correct?  It seems like I must have missed
something
2) Are their any OSS efforts around to produce an extended test generation
framework and maybe a repository of easily customizable tests?
3) If not, is anyone interesting in looking into the creation of such a
thing?

Regards,
Corey

I think, my write was bad (like my english).

Replier is a bad name, I propose PropertiesValueSetter :

--
package org.apache.commons.vfs;

/**
 * Interface call by FileSystem(Provider) when it needs informations.
 * This interface is a gateway, used by VFS to request information to
 * user application.
 * So the user application provide implementation for this Interface
 * (automatic answer, swing dialog box,...).
 */
public interface PropertiesValueSetter {

/**
 * Method call by FileSystem(Provider) to request properties.
 * Property's value is set by this method.
 * Property's name and defaultValue were set by caller.
 *
 * @param fs FileSystem fo which properties are needs.
 * @param message optionnal message used by
 *fs to describe needs (for end-user).
 * @param prop Array of requested properties (inout)
 * @exception Exception if problem.
 */
public void setProperties(FileSystem fs,
  String message,
  Property[] prop) throws Exception ;
}

--
package org.apache.commons.vfs;

/**
 * Data structure used to store request part
 * (name, defaultValue) and the answser part (value)
 * of property.
 *
 * predefine names are :
 * 
 *   user.login : when login connexion is needed.
 *   user.password : when password connexion is needed.
 * 
 */
public class Property {
public String name;
public String value;
public String defaultValue;
}

I need some study, I don't know lot of things on ssh, and JSch start
(and need JCE of JDK 1.4).

I think about a call back Interface, call by provider to required any
information (String). The user application provide implementation for
this Interface (automatic answer, swing dialog box,...).
like :

public interface Replier {

  public void needProperties(Property[] properties) throws Exception;
}

public class Property {
  public String name;
  public String value;
  public String defaultValue;
}

name and defaultValue are set by FSProvider before call needProperties.
value are set by Replier implementation.

Your opinion ?

[VFS][PATCH] remove some depends

[David BERNARD]

This pacth contains :

- remove of depends from commons-IO
- remove of depends from excalibur-i18n (see my previous mail :
  "[VFS] remove dependecies")
- add isWriteable() and isReadable() method on FileObject
   (=>remove isReadOnly)

!! I've also modified the name of the dist jar in build.xml.

Currently I'm not remove Resources.properties. I'll provide a possible
merged Resources.properties later. With it, user application of VFS
should internationalize FileSystemException.

Re: [VFS][PATCH] use root of zip as directory

[David BERNARD]

Hi,

> Adam is probably busy.

Ok, I'll wait, but my current VFS differ more each week :
- creation of the root of a ZipFileSystem as a Folder
- getParent return the parent of ParentLayer for root of layeredFileSystem
- remove of depends from commons-IO
- remove of depends from excalibur-i18n (see my previous mail :
   "[VFS] remove dependecies")
- add isWriteable() and isReadable() method on FileObject
   (=>remove isReadOnly)

>, but I have a few ideas.

Me too, provide a sshFileSystem via JSch (LGPL like Jcifs).

> What about making Ruper into a filesystem provider???
> It could just be a special layered provider that suplies the meta info using
> getAttribute

Ruper is a tool that use VFS, but the package rsrc.info could be
converted as a LayeredFS, it's a interesting suggestion.
The default MetaInfo extractor use the name of the file and apply Regexp
Then usage of this add a dependance of jakarta-regexp or jakarta-oro to
used with any JVM 1.2+

> And the search for a specific version could be implemented with some FileSelectors.

Maybe, yes, goal seem to be similar.

[VFS][PATCH] use root of zip as directory

[David BERNARD]

Hi,

I 'm working on 2 projects using VFS (FSUI a GUI ala MidnightCommander
and Ruper http://krysalis.org/cgi-bin/krywiki.pl?Ruper).

The attached patch include :
- creation of the root of a ZipFileSystem as a Folder
- getParent return the parent of ParentLayer for root of
layeredFileSystem

Like this Root of LayeredFileSystem like Zip could be manage more like a
"regular" folder.

[VFS] remove dependecies

[David BERNARD]

Hi,
May be a stupid suggestion but :

1. Dependence of commons-io could be remove by adding few line to
AbstractFileObject.

2. Dependence of excalibur-i18n could be remove by removing used of
Resource in exception. IMHO it was a bad practice,
 - the selected language is always the default locale (bad if exception
are raise on a server)
 - to provide other translation the user need to make a similar
directory structure, or to unjar, add, jar the lib.

So there isn't really internationalization. As replacement, I suggest to
:
 - add Exception.code as a key (like those in REZ)
 - add Exception.infos, an array of String that contains the arguments
 - set Exception.message = "Exception.code{Exception.infos[0],
Exception.infos[1], ...}"
 - provide a properties file that merged all Ressources.prop, but don't
use it in VFS only provide for user who want to humanize message.

By sample
final String message =
REZ.getString("set-attribute-not-supported.error");
throw new FileSystemException( message );

become
throw new FileSystemException("set-attribute-not-supported.error");

AND

final String message = REZ.getString( "list-children.error", name );
throw new FileSystemException( message, exc );

become
throw new FileSystemException( "list-children.error", name, exc);

And IMO, for FileType the use of Resources as constant is very
dangerous.

If you are OK, I could provide a patch for all those modifications.

[beanutils] An indexed and mapped property?

[Etienne Bernard]

Hello,

I am trying to use struts 1.1 into my project and I need to access
properties that are both mapped and indexed. I tried to use

  

But it calls getProperty("name") and not getProperty("name", 0).

I had a look at the code and what I saw suggests that this syntax is not
supported. I'd like to know if you are planning to support such syntax
or if you are willing to accept patches (provided that I manage to code
the feature) ?
