Null pointer in ClassWorld.getImportRealm()

2009-08-20T12:43:37Z

Hello,
well I am playing with ClassWord/Realm concept
and have found that
importRealmMappings is never initialized in ClassWorld, however
it is accessed in getImportRealm and as result I get

Hi,

Using plexus appserver, how do you set jetty's min/max threads from a config file like the jetty port?

Thanks,

As far as I know they use ASL v2; however that is just as we understand it.

Your best bet is to check the distributions; as they should include
the licence information.

Cheers,

Ben

Re: [plexus-utils]/[plexus-archiver] Unarchiver hangs on linux if a directory contains a dollar in his name

The unarchiver hangs when a directory in the archive contains a dollar

I'm not sure if the problem comes from a wrong usage of plexus-utils on
plexus-archiver or from plexus-utils itself.

I solve it modifying the BourneShell.java in plexus-utils, but
I'm not successful to reproduce it in a plexus-utils

testcase.

I put in attachement the patches for plexus-utils (with the test-case
not reproducing the problem ;)) and for plexus-archiver (add a failing test
when the plexus-utils patch is not applied).

What are you thinking about this problem ?

Maven plugin:merge-descriptors: how to configure the resources parameter?

2009-03-19T06:00:38Z

Hello,

I am using plexus-maven-plugin:1.3.8 on a custom maven plugin. The
plugin already contains a components.xml containing 2 lifecycle
mappings for custom Maven packaging types. I wanted to add a few other
Plexus components using Javadoc annotations. I configured both the
descriptor goal and the merge-descriptors goal. However, I can't seem
to get the resources parameter correctly configured to only pickup the
folders of my custom written and generated components.xml. I started
with just folder names between the resource tags in the POM
configuration, but eventually tried to replicate the object structure
of such a resource in XML:

<plugin>
<groupId>org.codehaus.plexus</groupId>
<artifactId>plexus-maven-plugin</artifactId>
<version>1.3.8</version>
<executions>
<execution>
<id>generate-component-descriptors</id>
<goals>
<goal>descriptor</goal>
</goals>
<configuration>
<outputDirectory>${basedir}/target/generated-resources</outputDirectory>
</configuration>
</execution>
<execution>
<id>merge-component-descriptors-with-lifecycles</id>
<goals>
<goal>merge-descriptors</goal>
</goals>
<configuration>
<resources>
<resource>
<fileSet>
<directory>${basedir}/resources/xml/</directory>
</fileSet>
</resource>
<resource>
<fileSet>

<directory>${basedir}/target/generated-resources/</directory>
<patternSet>
<includes>**/*.xml</includes>
</patternSet>
</fileSet>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>

Nothing seems to work. Any input on how to correctly configure the
merge-descriptors goal would be much appreciated.
As a work-around, I'm currently generating my descriptor to the folder
"web" as this seems to be picked up. This folder is not cleaned
however, so it should remain a temporary workaround.

I've been trying NetBeans because I've found Eclipse to be rather

Re: Why does plexus fail to initialize singleton instance?

print the output of mvn dependency:tree to see if there are other plexus jars or if the versions are being altered at build time perhaps?

Would need to see your POM, but with a version that far back you might be getting bitten by the component api JAR. In more current versions we have place everything in one JAR. Generally when the lifecycle methods are not being executed it's because the component api is loaded and the same class in the new plexus container JAR is not the same so the instanceof check for a particular lifecycle phase being executed fails and so that lifecycle phase does not run.

First make sure that you don't have the component api JAR anywhere. This is usually the cause.

Re: Why does plexus fail to initialize singleton instance?

Hi Jason,
When i use Embedder.lookup() to start my app, plexus works well at version 1.0-alpha-25.
but when i use DefaultPlexusContainer.lookup() to start app, plexus do not execute the initilize() interface at version 1.0-alpha-50-SNAPSHOT(coz there is not an Embedder in this version).

The pom file is as below (relate part):

Would need to see your POM, but with a version that far back you might be getting bitten by the component api JAR. In more current versions we have place everything in one JAR. Generally when the lifecycle methods are not being executed it's because the component api is loaded and the same class in the new plexus container JAR is not the same so the instanceof check for a particular lifecycle phase being executed fails and so that lifecycle phase does not run.

First make sure that you don't have the component api JAR anywhere. This is usually the cause.

the initilize() of AccountRepositoryHolderDBImpl DOES NOT be executed by container now, do you why?

the configuration is as below:

<role-hint>AccountRepositoryHolder</role-hint>
<implementation>net.java.dev.openim.data.storage.AccountRepositoryHolderDBImpl</implementation>

<regexpSearch>false</regexpSearch>
</configuration>
</component>

Thanks,

Deprecate StringInputStream and StringOutputStream
--------------------------------------------------

Key: PLXUTILS-70
URL: http://jira.codehaus.org/browse/PLXUTILS-70
Project: Plexus Utils
Issue Type: Improvement
Affects Versions: 1.5.1
Reporter: Benjamin Bentmann
Attachments: deprecate-string-streams.patch

The mentioned classes do not handle character encoding properly. For instance, they don't guarantee an identity transformation when being pipelined. It's a one liner to replace these classes with JRE classes so I don't see a benefit in fixing and maintaining this code.
