ClassNotFoundException: org.apache.activemq.xbean.XBeanBrokerService

Hello,
I have a camel route that has org.apache.camel dependencies at version 2.9.1
When I try to install in fuse esb I get an error (because camel features are all at version 2.8.0)
So when I rebuild the bundle with 2.8.0 components and try to install I now get:
java.lang.ClassNotFoundException: org.apache.activemq.xbean.XBeanBrokerService not found by org.apache.xbean.spring 87;
Can anybody advise how to fix this?
thanks. |

Hi,
Did you camel router bundle already import org.apache.activemq.xbean package?

Hi Freeman, thanks for replying.
No my bundle does not have org.apache.activemq.xbean in its dependencies - it runs fine in the Eclipse IDE - its only when I deploy it to servicemix that I see this dependency?

OK , ISWYM
I added the dependency that contains the XBeanBrokerService class:
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-core</artifactId>
<version>5.5.1</version>
<type>bundle</type>
<scope>compile</scope>
</dependency>
But I'm still getting exactly the same ClassNotFound exception in Servicemix? |

Hi,
You need import org.apache.activemq.xbean package in maven-bundle-plugin, add the dependency doesn't mean it will import such package.

Hi Freeman, many thanks your post; it was a great help and much appreciated.
I added the following configuration:
<configuration>
<instructions>
<Export-Package>org.apache.activemq.xbean</Export-Package>
<Include-Resource>{maven-resources}, {maven-dependencies}</Include-Resource>
</instructions>
</configuration>
Which solved the XBeanBrokerService issue.
But then I was getting message exchange errors due to:
Caused by: java.lang.NoClassDefFoundError: org/apache/log4j/Appender
So I added log4j to the Exported Packages:
<Export-Package>org.apache.log4j,org.apache.log4j.config,org.apache.log4j.helpers,
* org.apache.log4j.or,org.apache.log4j.pattern</Export-Package>*
But I'm now getting:
karaf@root> osgi:start 295
Error executing command: Unable to resolve module xxx.CamelTestJMS http://295.0 because it is exposed to package 'org.apache.log4j' f
rom xxx.CamelTestJMS http://295.0 and org.ops4j.pax.logging.pax-logging-api http://3.0 via two dependency chains.
Chain 1:
xxx.CamelTestJMS http://295.0
import: (&(package=org.apache.log4j)(version>=0.0.0)(!(version>=1.0.0)))
|
export: package=org.apache.log4j
xxx.CamelTestJMS http://295.0
Chain 2:
xxx.CamelTestJMS http://295.0
import: (package=org.apache.log4j.spi)
|
export: package=org.apache.log4j.spi; uses:=org.apache.log4j
export: package=org.apache.log4j
org.ops4j.pax.logging.pax-logging-api http://3.0
I Have these dependencies in my pom.xml:
<dependency>
- <groupId>org.slf4j</groupId>*
- <artifactId>slf4j-api</artifactId>*
- <version>1.6.1</version>*
- </dependency>*
- <dependency>*
- <groupId>org.slf4j</groupId>*
- <artifactId>slf4j-log4j12</artifactId>*
- <version>1.6.1</version>*
- </dependency>*
- <dependency>*
- <groupId>log4j</groupId>*
- <artifactId>log4j</artifactId>*
- <version>1.2.16</version>*
- </dependency>*
Any ideas ?
Many thanks.
Barry. |

You need Import-Package but not Export-Package for log4j packages

Thanks Freeman, apologies for what these must be basic questions.
I changed the log4j to Import-Package but then got an error when building in eclipse:

Hi Freeman,
When I use Import-Package for log4j I now get:
org.osgi.framework.BundleException: Unresolved constraint in bundle xxx.CamelTestJMS 311: Unable to resolve 311.1: missing req
uirement http://311.1 package; (&(package=org.apache.log4j)(version>=0.0.0)(!(version>=1.0.0)))

Hi,
The log4j package version available in the OSGi container is 1.2.15, so you need import log4j package with correct version range accordingly. Currently the version range is http://0.0.0, 1.0.0, that's why you see such exception.

Hi Freeman,
I tried:
<Import-Package>org.apache.activemq.xbean,org.apache.log4j,org.apache.activemq.broker,
org.apache.log4j.config; org.apache.log4j.helpers; org.apache.log4j.or; org.apache.log4j.pattern; version="1.2.15", *</Import-Package>
But still get this error when I start the bundle:
karaf@root> osgi:start 366
Error executing command: Unresolved constraint in bundle xxx.CamelTestJMS 366: Unable to resolve 366.0: missing requirement [3
66.0] package; (&(package=org.apache.log4j.config)(version>=1.2.15))
Is my syntax incorrect for Import-Package ?
thanks,
Barry. |
