I want to use Commons-DBCP 2.0.
On official site i found:
Users upgrading to 2.x should be aware that the Java package name has changed, as well as the Maven co-ordinates, since DBCP 2.x is not binary compatible with DBCP 1.x.
But what are the new coordinates? As expected here are only 1.x available.
Is it this one?
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-dbcp2</artifactId>
<version>2.0</version>
</dependency>
Most apache projects have aligned with the org.apache.commons groupid.
And you seemed to want the DBCP 2.
And BTW, maven central has its own search facility:
http://search.maven.org/#search|ga|1|commons-dbcp
You can use the maven central repository : central maven search.
In your case commons-dbcp2.

How to use the Liberty's distributedmap feature in a Java application?
Where I can find the required Maven dependencies (com.ibm.websphere.cache..)?
The Maven dependencies for WebSphere features like the DistributedMap are defined in the https://github.com/WASdev/ci.maven.tools repository and they are published on Maven central.
The following dependency loads all APIs:
<dependency>
<groupId>net.wasdev.maven.tools.targets</groupId>
<artifactId>liberty-apis</artifactId>
<version>${liberty.dependency.version}</version>
<scope>provided</scope>
<type>pom</type>
</dependency>
The Maven coordinates for the distributedMap API would be:
<dependency>
<groupId>com.ibm.websphere.appserver.api</groupId>
<artifactId>com.ibm.websphere.appserver.api.distributedMap</artifactId>
<version>2.0.68</version>
</dependency>
Each release of Liberty will have a different version, but that is from 22.0.0.9 the latest version as of this response. I found this by using search.maven.org and searching for distributedMap. This should work for other features APIs as well.
I'm trying to migrate from Jersey 1.x (1.2) to 2.x (2.6), I have trouble identifying the exact maven dependencies, jersey documentation is not comprehensive enough, it doesn't mention what maven dependencies are needed for the new version.
Does anyone have comprehensive list of maven dependencies needed for Jersey 2.x (2.6)?
Jersey doc
https://jersey.java.net/documentation/latest/migration.html#mig-1.x
For a servlet environment, the only dependency you need is
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<artifactId>jersey-container-servlet</artifactId>
<version>2.6</version>
</dependency>
This will pull in all you need. If you are in a servlet 2.5 environment, then you would use this instead
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<artifactId>jersey-container-servlet-core</artifactId>
<version>2.6</version>
</dependency>
Further information about 2.5 servlet, can be seen here
Alternatively, you could create a project from a Maven archetype, as seen here
UPDATE
Just as a note, the significance of using Jersey 2.6 is that it is the last version to support Java 6. If this is not a requirement for you, I would recommend using the latest version.
i am new to spring framework. When i try to download required jar files for spring, then there is 2 options for same classes-
org.springframework.xyz-2.5.6.A.jar and spring-xyz-2.5.6.RELEASE.jar.
I want to know what is the difference and which is recommended to use?
thanks.
The org.springframework.xyz version is the artifact ID used by SpringSource in their Enterprise Bundle Repository, a self-contained set of OSGi-compliant JARs for both Spring and non-Spring artifacts. The spring-xyz version is the standard non-OSGi version available on Maven Central.
If you're using OSGi then use the EBR JARs, if you're not then use the standard ones.
The current Maven dependency for spring-context is
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>
The resulting JAR is spring-context-3.2.4.RELEASE.jar.
So the second name looks OK to me.
I have created a maven web project using the below site.
http://www.mkyong.com/maven/how-to-create-a-web-application-project-with-maven/
I have performed all the steps given there and executed a simple hello world program. Now, I have to include spring dependencies into my eclipse web project.
So
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring</artifactId>
<version>3.1.2</version>
</dependency>
In the dependencies tag, I added the above configuration. Now, it is saying as below:
unable to find jars from the repositories (local and as well as remote)
It gave suggestion to execute the command:
mvn install -artifactid=springframework (something like this)
But when I mentioned version as 2.5.6 it's correctly taken. Is it the problem with the version 3.1.2 being unavailable at maven repository? How do I get the latest versions if maven is not working properly for latest versions?
It also gave me the suggestion to go for manual download and put in local repository.
The Maven coordinates changed over time.
Try:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>org.springframework.core</artifactId>
<version>3.1.2.RELEASE</version>
</dependency>
OR Try:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>3.1.2.RELEASE</version>
</dependency>
I'll just find if there is an all-in-one POM or dependency. But "spring-full" looks 1.2.x only and "spring" 2.5.x. CHECKED: Can't find one I've been using separate modules in all projects for sometime (this is better anyway, fine grained dependencies).
The location you can search is at http://ebr.springsource.com/repository/app/
for 3.1.2 see http://ebr.springsource.com/repository/app/library/version/detail?name=org.springframework.spring&version=3.1.2.RELEASE&searchType=librariesByName&searchQuery=spring
Spring have changed their repository URL and online locations at least 3 times to my knowledge over the past 4 years. So I'd look for current information on their website about setting up a Maven <repositories> config to obtain their JARs. Beware of articles with out of date information :(
Also notice the artifactId is different in the 2 example this is another gotcha issue with spring. The "org.springframework.core" are their EBR and OSGi compliant versions of their software. The "spring-core" is the older pre-OSGi co-ordinates. Find what works for you and don't mix them in the same project. For example I am using "spring-core" because I use 3.2.0.M2 which are Milestone releases. But the production release EBR co-ordinates are the best to use.
Sorry for so many edits... but it has been a minefield even if you understand the heritage of getting Spring Source software.
I have a maven plugin which is using hsqldb 1.8.0.10. In my pom.xml from the plugin, it is declared like this:
<dependency>
<groupId>hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<version>1.8.0.10</version>
</dependency>
But if I run that plugin from another maven project, and that project has a newer version of hsqldb (for instance 1.9.0), how can I configure my plugin that he will use the newest version of hsqldb, without changing it's pom.xml?
And is it possible to do this the other way around as well? If my other maven project uses hsqldb 1.7.0 (for instance), that he will use the 1.8.0.10 version which is specified in the maven plugin itself?
I hope someone can answer my question.
Kind regards,
Walle
Your main question is possible, but it might not work properly if the plugin doesn't work with the newer code for any reason.
A plugin can have it's own personal dependencies section, and will use standard Maven dependency resolution, choosing the highest version requested. So, you can do
<plugin>
<groupId>some.group.id</groupId>
<artifactId>some.artifact.id</artifactId>
<version>someversion</version>
<dependencies>
<dependency>
<groupId>hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<version>1.9.0</version>
</dependency>
</dependencies>
</plugin>
I don't think going the other way around is possible, though.
use properties place holder for the version, say ${hsqldb.version} then declare in different project pom the version you want to put in it
