I have added dependency guava for using Multimaps and also I have added Hive dependency in my project.
I am getting the following error while compiling application.
An attempt was made to call the method com.google.common.collect.Multimaps.asMap(Lcom/google/common/collect/ListMultimap;)Ljava/util/Map; but it does not exist. Its class, com.google.common.collect.Multimaps, is available from the following locations:
jar:file:/Users/sreenivas/.m2/repository/org/apache/hive/hive-exec/1.2.1/hive-exec-1.2.1.jar!/com/google/common/collect/Multimaps.class
jar:file:/Users/sreenivas/.m2/repository/com/google/guava/guava/25.1-jre/guava-25.1-jre.jar!/com/google/common/collect/Multimaps.class
It was loaded from the following location:
file:/Users/sreenivas/.m2/repository/org/apache/hive/hive-exec/1.2.1/hive-exec-1.2.1.jar
Action:
Correct the classpath of your application so that it contains a single, compatible version of com.google.common.collect.Multimaps.
Can anyone suggest me how to take the latest version dependency.
It is caused by the package hive-exec include /com/google/common/collect/Multimaps.class, as shown in picture:
If you have to include these two jar (hive-exec-1.2.1.jar and guava-25.1-jre.jar), you'd better fix hive-exec's source code and repackage it.
I have maven project where i am adding the dependencies which are not resolvable as below.
My servlet is as follows:
LocaleUtil is getting resolve but its sub packages are throwing error when including.
I have tried invalidate cache and restart. But this didn't work for me.
Thanks,
The packages you are trying to import are internal, non-exported packages of the bundle com.adobe.granite.i18n. In fact, that bundle only exports the following packages:
Export-Package
com.adobe.granite.i18n {version=1.0, imported-as=[1.0.0,1.1)}
com.day.cq.i18n {version=5.4.0}
You should not attempt to use private packages of a library. Limit yourself to using only the exported API.
Inside ee.j2se-1.8 the package org.w3c.dom is included.
org.osgi.framework.system.packages = \
...
org.w3c.dom,\
...
org.osgi.framework.bootdelegation = \
...
org.w3c.*,\
org.xml.*,\
....
The bundle xml-apis_1.4.1.20140905-131237.jar contains the same package org.w3c.dom, but with one important class more ... ElementTraversal.class more.
So here my questions...
How can I provide the missing class inside my Equinox OSGi runtime?
You are suffering from the fact that people do not take packages seriously. We have a similar problem in the jta API. The version delivered by the VM is not identical to the version that is delivered as a special package.
The solution is to include the JAR with the extra packages on the class path where the framework resides. It looks like you're using bnd (good!) so this would look like:
-runpath: xml-apis__xml-apis;version="[1.4.1,2.0.0)"
If this had been a bundle with proper exports then you would have automatically gotten its exports as system packages. Looking at the packages in this bundle it seems all packages are already in the standard exports of the VM. However, if you have packages int his JAR that are not exported by the VM then you can add them as follows:
-runsystempackages: javax.xml.foo
I am trying to add bouncy castle as a service provider to my java product running on apache karaf.
When I am trying to start the bundle which imports bouncy castle I get an error message
java.lang.Exception: Could not start bundle mvn:com.xxx.yyy.zzz/docsservice/1.0.0-SNAPSHOT/war in feature(s) server-docs-1.0.0-SNAPSHOT: Unresolved constraint in bundle docs [245]: Unable to resolve 245.0: missing requirement [245.0] osgi.wiring.package; (&(osgi.wiring.package=org.bouncycastle.jce.provider)(version>=1.51.0))
at org.apache.karaf.features.internal.FeaturesServiceImpl.startBundle(FeaturesServiceImpl.java:472)
In the pom file I imported the package org.bouncycastle.jce.provider and I added bouncycastle as a dependency.
Also, i made all the changes described on this page,
http://karaf.apache.org/manual/latest/users-guide/security.html, see below
I put provider jar in lib/ext
I Modified the etc/config.properties configuration file to add the following property
org.apache.karaf.security.providers = xxx,yyy
org.apache.karaf.security.providers = org.bouncycastle.jce.provider.BouncyCastleProvider
I provided access to the classes from those providers from the system bundle so that all bundles can access those. I did this by modifying the org.osgi.framework.bootdelegation property in the same configuration file:
org.osgi.framework.bootdelegation = ...,org.bouncycastle*
On some forum I found another suggestion so I modified
*org.osgi.framework.system.packages.extra = * in the config.properties as well and I added here packages exported from bouncycastle
Nonetheless I wasn't able to load the bundle successfully. I looked at all the bundles loaded by karaf and none of them was exporting bouncy castle package.
What am I missing here? How can I make the bundles to start?
By adding the package to the boot delegation you made it available like java.* packages. For these you do not need an Import-Package. So one way would be to remove the Import-Package for it in your bundle. You should rather explore though if you can work without boot delegation.
Please try to remove the boot delegation and add the package to
org.osgi.framework.system.packages.extra = org.bouncycastle.jce.provider
This adds the package to the packages the system bundle exports. It should then be wired to your bundle.
I am trying to publish some web services (using EndpointImpl.publish()) but I am gettings this error:

Require-Bundle =
org.apache.cxf.bundle
I am not sure what else I need to do.
in case it is important. the container is a karaf 2.2.7
to address pooh's answer:
1- cxf-bundle is exporting this package: org.apache.cxf.jaxws.spi;version="2.4.3.fuse-01-02"
2- bundle was started. the error was during runtime.
3- the manifest was created using maven-bundle-plugin which should create the entire list
4- the error happen while creating a webservice endpoint:
TopologyIFPortType impl = new TopologyWS();
String addressTopology = "http://localhost:" + port
+ "/nsp/webservice/topology";
topologyEndpoint = (EndpointImpl) Endpoint.create(impl);
topologyEndpoint.getFeatures().add(new WSAddressingFeature());
topologyEndpoint.publish(addressTopology);

The version of CXF you use seem to be quite old. You should try with the current release 2.6.1. In 2.6 a lot of OSGi improvements were introduced.
You can install it using:
features:chooseurl cxf 2.6.1
features:install cxf
Don't worry, OSGi gives you full access to the information which bundle uses which package etc. You only have to know how to ask the system to give you the info you need for debugging the problem.
Unfortunately I am not familiar with karaf console commands, I am working more with ProSyst's mBeddedServer OSGi framework, but since all this is standard in OSGi, I can tell you what to look for and you can find the needed commands in karaf.
So, check the following:
1. Is Apache cxf bundle successfully installed? Is it in the "active" state?
(from your posting it seems that it is)
What is the version of the org.apache.cxf.jaxws.spi package that it exports?
This is different from the cxf bundle version!!!
In order to see the package version, look inside the manifest of the cxf bundle, and look for the Export-package header.
Is your bundle installed and started successfully? Is it in the active state?
If the error "Provider not found" appears during starting of your bundle, then your dependencies are not matching the provided packages from the cxf bundle, see point 2.
If, however, the error appears during runtime, it could have several causes:
You haven't imported all needed packages in your manifest. Try using analysis tools which can generate the manifest for you based on your source code.
or:
The code which does the publishing is located e.g. on the system classpath and uses the system classloader, which in OSGI due to modularity and security reasons doesn't have access to the bundle classloaders.
Check what is provided by the system classpath instead of as OSGi bundles. Anything there which uses Class.forName or other reflection methods won't work in the modular OSGi framework.
There are also other possibilites, but you'll need to provide more info. Was there an exception stack trace? What classes are involved in this piece of code and where on the classpath are they located? etc.
