When deploying JxBrowser with OSGi, I end up with the following error when I try to build my product :
[ant] !MESSAGE Missing requirement: JxBrowser 6.6.1 6.6.1 (com.teamdev.jxbrowser.chromium 6.6.1) requires 'package sun.awt.windows 0.0.0' but it could not be found
the sun.awt.windows package is part of the JRE (in rt.jar), and I don't really understand why the JxBrowser OSGi bundles cannot find it. Any idea as to why this is would be greatly appreciated.
Thanks for the help!
Removing the package import from the manifest file, like Vladimir suggested solved the problem.

I'm new to Corda, so am following the "Getting started developing CorDapps".
On my MacBook Pro, I have:
- installed the JDK, IntelliJ Community edition and Git,
- have downloaded the sample project (using git clone) by following Step One)
- created an IntelliJ project (by following Step Two)
but, when following instructions for Deploy the CorDapp locally (using ./gradlew clean deployNodes), I get the following errors:
Task :contracts-java:compileJava FAILED
/Users/samples/cordapp-example/contracts-java/src/main/java/com/example/state/IOUState.java:5: error: package com.google.common.collect does not exist
import com.google.common.collect.ImmutableList;
^
... and another 3 similar.
I've searched google, gradle and IntelliJ forums, but cannot find anyhting that helps resolve my issue.
Can someone point me in the right direction please?
Thanks a lot!
As recommended here, Open IOUState.java and:
Remove this import: import com.google.common.collect.ImmutableList;
Modify ImmutableList.of(new IOUSchemaV1()) to Arrays.asList(new IOUSchemaV1())
The recent 4.4 upgrades have removed the ImmutableList from the dependencies. You could change the ImmutableList.of to Arrays.asList or Collections.singletonList as a workaround.
Thanks for raising this, we will fix it ASAP.
I'm trying to implement adding maven dependencies to my ant build using this article. I beleive I have everything set up as indicated by the article but since it is not working I must be missing something. I am getting this error:
Could not load definitions from resource org/apache/maven/artifact/ant/antlib.xml. It could not be found.
My searches for this error seem to imply I an missing maven-ant-tasks-2.1.3.jar. However, it is in the path indicated by the classpath. Can someone help be debug this? TIA.
I found at least part of the problem. I had the wrong file name in the classpath. It was maven-ant-tasks.jar and it should have been maven-ant-tasks-2.1.3.jar.
Unfortunately I now have a different problem which I think implies a corrupt jar file.
Unable to obtain resource from /usr/build/lib/maven-ant-tasks-2.1.3.jar: java.util.zip.ZipException: error in opening zip file
Downloading the jar file again did not help.
Never mind. Apparently the Apache maven web site has a corrupt version. I downloaded it from the mvnrepository and that worked.
I am attempting to create a Websockets- based application using the Grizzly Websockets bundles. I am doing this in Apache Felix using Bndtools.
Unfortunately, I seem to have all the needed dependencies, but the Grizzly bundles are failing to load due to the following failure:
org.glassfish.grizzly.websockets-server-2.3.23Unable to resolve
org.glassfish.grizzly.websockets-server [23](R 23.0): missing
requirement [org.glassfish.grizzly.websockets-server [23](R 23.0)]
osgi.wiring.package; (osgi.wiring.package=sun.misc) Unresolved
requirements: [[org.glassfish.grizzly.websockets-server [23](R 23.0)]
osgi.wiring.package; (osgi.wiring.package=sun.misc)]
I have researched this failure, originally looking for a bundle, only to discover that apparently this is some kind of JVM library that is really not needed. I have seen workarounds and solutions that involve adding a line to a conf/config.properties file:
org.osgi.framework.system.packages.extra=sun.misc
I understand that this is a dangerous workaround, and there are rumors of "safer" solutions to this problem. They all involve making changes to tags or to the config.properties file.
Unfortunately, in a Bndtools environment, there are apparently no such tags or files for me to edit!
Or, at least, I cannot find these things in my Bndtools project.
Is there some way to fix this "sun.misc" problem within a Bndtools- based project? I am using Bndtools repository and am wondering which of the various "bnd" files I need to edit, as well as what to put into those files.
Someone please advise...
You need to add -runsystempackages: sun.misc to the bnd/bndrun file.
The best tool for that is https://github.com/diffplug/osgiX
You just will change PKG=sun.misc(or another package) in gradle.properties and run gradlew build.
It will generate bundle-fragment, which you will can add to your class path.
The bundle then contains:
Manifest-Version: 1.0
Export-Package: sun.misc
Fragment-Host: system.bundle; extension:=framework
Bundle-ManifestVersion: 2
Bundle-License: public domain - http://unlicense.org/
Bundle-SymbolicName: com.diffplug.osgi.extension.sun.misc
Bundle-Version: 0.0.0
I installed Hadoop version 1.0.3 and its related eclipse plugin successfully. All the Hadoop functionalities and examples are working pretty well, but when I want to use its plugin on eclipse, it could not connect to hdfs and I get the error:
An internal error occurred during: "Connecting to DFS localhost".
org/apache/commons/configuration/Configuration.
could anybody help me how to solve this problem!
Thanks
You are facing this problem because the plugin is missing some necessary jars. In order to solve the problem you need to rebuild the plugin after including the necessary jars. I have seen this kind of questions a lot on SO, and they all point out to the same thing. Please see these links :
Eclipse Hadoop plugin issue(Call to localhost/127.0.0.1:50070 )Can any body give me the solution for this?
Hadoop eclipse mapreduce is not working?
Installing Hadoop's Eclipse Plugin
I did follow the following blog instructions to make Hadoop eclipse plugin 1.0.4 :
http://iredlof.com/part-4-compile-hadoop-v1-0-4-eclipse-plugin-on-ubuntu-12-10/
but it seems it has some missing parts like:
in MANIFEST.MF you should add:
/lib/commons-cli-1.2.jar
and in build-contrib.xml you should also add:
<property name="commons-cli.version" value="1.2"/>
I hope these are useful!
you must run hadoop with command line first!!

i am trying to installing selenium-server-standalone-2.0b1.jar actually for that i have to set all jar files into the classpath of a java project. But i don't know that where all the jars under this folder "selenium-server-standalone-2.0b1.jar" ? and how to install selenium-server-standalone-2.0b1.jar? Please help me out
I didn't get your question correctly. If you are looking for the jars,you can download from the following sites.Try to used the new jars,as these come with lot of fixes.
Just add to classpath & ready to go.
