Following the tutorial about installing Orion, I installed contextBroker-0.5.0-1.x86_64.rpm and contextBroker-tests-0.5.0-1.x86_64.rpm.
After all, I decided to run Orion, but when I do using # contextBroker I get this notification
"contextBroker: error while loading shared libraries: libmicrohttpd.so.10: cannot open shared object file: No such file or directory"
I've read on the Internet that "libmicrohttpd.so.10" belongs to contextBroker-0.5.0-1.x86_64.rpm, so I don't know what the problem is.
Version 0.5.0 is very old. I would recommend you to install the newest one that, at time of this writting, is 0.14.0.
You can install it in the following way:
Remove the old version (rpm -e contextBroker)
Configure FI-WARE yum respository (explained here)
Install contextBroker running: yum install contextBroker
Ensure you have the newest version: contextBroker --version
I'm configuring a vagrant box using chef and then deploying my app using capistrano.
my chef recipe to install bundler is the following:
include_recipe "rbenv"
include_recipe "rbenv::ruby_build"
rbenv_ruby node[:rbenv][:ruby] do
global true
end
rbenv_gem "bundler" do
ruby_version node[:rbenv][:ruby]
end
using the Riot rbenv cookbook
When I try using the bundle with capistrano I figured that the executed bundle is one that was preinstalled on the box, rather than the one installed by chef.
Here's the problem:
$ which bundle
/opt/rbenv/shims/bundle
$ sudo which bundle
/usr/bin/bundle
$ sudo su -
root# which bundle
/opt/rbenv/shims/bundle
Basically it appears that Capistrano runs the commands using the second form, were it uses the /usr/bin/bundle.
I've tried running:
$ sudo bundle
/usr/lib/ruby/vendor_ruby/bundler/rubygems_ext.rb:8:in `require': no such file to load -- rubygems (LoadError)
from /usr/lib/ruby/vendor_ruby/bundler/rubygems_ext.rb:8
from /usr/lib/ruby/vendor_ruby/bundler.rb:11:in `require'
from /usr/lib/ruby/vendor_ruby/bundler.rb:11
from /usr/bin/bundle:4:in `require'
from /usr/bin/bundle:4
and I obtain exactly the same exception I see in Capistrano.
If I manually uninstall bundler then here's what I obtain:
$ bundle
Bundler::GemfileNotFound
$ sudo bundle
sudo: bundle: command not found
$ sudo su -
root# bundle
Bundler::GemfileNotFound
UPDATE
I've figured that the whole ruby version is not available for sudoers:
$ ruby -v
ruby 2.0.0p353 (2013-11-22 revision 43784) [x86_64-linux]
$ sudo ruby -v
ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]
even more troubles.
Can you help me ?
thanks.
The problem is not that the rbenv-managed Ruby is not available to sudoers. The problem is that the system Ruby is used by default, unless overridden by something else -- usually .bashrc or a /etc/profile.d/* or such.
Since capistrano doesn't source any of these files, it uses the system Ruby.
You should tell cap to use the rbenv bin paths before the system ones by adding:
set :default_environment, {
'PATH' => "/opt/rbenv/shims:/opt/rbenv/bin:$PATH"
}
to your deploy.rb file.
Update
In Capistrano v3, the :default_environment has been renamed to :default_env.
Apparently tweaking with the default_env is a possibility, but not the preferred way.
as:
set :default_environment, {
'PATH' => "/opt/rbenv/shims:/opt/rbenv/bin:$PATH"
}
is not maintained by capistrano and probably even dangerous.
The preferred way is to look into the program one wants to run for a way to fix this.
In particular my problem: the RVM needs to be initialized upon shell startup, and any RVM installation tool will include your .bashrc with the call to the proper init script at the end of the file. Also at the beginning of .bashrc there's a command that exits the script when it's called on a non interactive shell.
Accidentally Capistrano runs the scripts on a non interactive shell, so when it calls RVM commands they are not initialized, in the non interactive shell.
The solution in my case was to edit the .bashrc file in chef so to call the RVM init script before exiting.
I am using Tomcat 7 in Eclipse on Windows. When starting Tomcat, I am getting the following info message:
The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path
What does this mean and how can I provide the APR library?
It means exactly what it says: "The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path"
The library referred to is bundled into an OS specific dll (tcnative-1.dll) loaded via JNI. It allows tomcat to use OS functionalities not provided in the Java Runtime (such as sendfile, epoll, OpenSSL, system status, etc.). Tomcat will run just fine without it, but for some use cases, it will be faster with the native libraries.
If you really want it, download the tcnative-1.dll (or libtcnative.so for Linux) and put it in the bin folder, and add a system property to the launch configuration of the tomcat server in eclipse.
-Djava.library.path=c:\dev\tomcat\bin
Unless you're running a production server, don't worry about this message. This is a library which is used to improve performance (on production systems). From Apache Portable Runtime (APR) based Native library for Tomcat:
Tomcat can use the Apache Portable Runtime to provide superior
scalability, performance, and better integration with native server
technologies. The Apache Portable Runtime is a highly portable library
that is at the heart of Apache HTTP Server 2.x. APR has many uses,
including access to advanced IO functionality (such as sendfile, epoll
and OpenSSL), OS level functionality (random number generation, system
status, etc), and native process handling (shared memory, NT pipes and
Unix sockets).
On RHEL Linux just issue:
yum install tomcat-native.x86_64
/Note:depending on Your architecture 64bit or 32bit package may have different extension/
That is all. After that You will find in the log file next informational message:
INFO: APR capabilities: IPv6 [true], sendfile [true], accept filters [false], random [true].
All operations will be noticeably faster than before.
Installation the native library on Ubuntu server with:
sudo apt-get install libtcnative-1
If that does not work tomcat-native needs to be installed
Install Oracle java7:
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer
sudo apt-get install oracle-java7-set-default
Install tomcat apr:
wget http://apache.mirror.anlx.net//apr/apr-1.5.0.tar.gz
tar zxvf apr-1.5.0.tar.gz
rm apr-1.5.0.tar.gz
cd apr-1.5.0
sudo ./configure
sudo make
sudo make install
export LD_LIBRARY_PATH='$LD_LIBRARY_PATH:/usr/local/apr/lib'
Install tomcat tomcat-native:
wget http://mirrors.ukfast.co.uk/sites/ftp.apache.org//tomcat/tomcat-connectors/native/1.1.29/source/tomcat-native-1.1.29-src.tar.gz
tar zxvf tomcat-native-1.1.29-src.tar.gz
rm tomcat-native-1.1.29-src.tar.gz
cd tomcat-native-1.1.29-src/jni/native
JAVA_HOME=/usr/lib/jvm/java-7-oracle
sudo ./configure --with-apr=/usr/local/apr --with-java-home=$JAVA_HOME
sudo make
sudo make install
I just went through this and configured it with the following:
Ubuntu 16.04
Tomcat 8.5.9
Apache2.4.25
APR 1.5.2
Tomcat-native 1.2.10
Java 8
These are the steps i used based on the older posts here:
Install package
sudo apt-get update
sudo apt-get install libtcnative-1
Verify these packages are installed
sudo apt-get install make
sudo apt-get install gcc
sudo apt-get install openssl
Install package
sudo apt-get install libssl-dev
Install and compile Apache APR
cd /opt/tomcat/bin
sudo wget http://apache.mirror.anlx.net//apr/apr-1.5.2.tar.gz
sudo tar -xzvf apr-1.5.2.tar.gz
cd apr-1.5.2
sudo ./configure
sudo make
sudo make install
verify installation
cd /usr/local/apr/lib/
ls
you should see the compiled file as
libapr-1.la
Download and install Tomcat Native source package
cd /opt/tomcat/bin
sudo wget https://archive.apache.org/dist/tomcat/tomcat-connectors/native/1.2.10/source/tomcat-native-1.2.10-src.tar.gz
sudo tar -xzvf tomcat-native-1.2.10-src.tar.gz
cd tomcat-native-1.2.10-src/native
verify JAVA_HOME
sudo pico ~/.bashrc
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
source ~/.bashrc
sudo ./configure --with-apr=/usr/local/apr --with-java-home=$JAVA_HOME
sudo make
sudo make install
Edit the /opt/tomcat/bin/setenv.sh file with following line:
sudo pico /opt/tomcat/bin/setenv.sh
export LD_LIBRARY_PATH='$LD_LIBRARY_PATH:/usr/local/apr/lib'
restart tomcat
sudo service tomcat restart
On Mac OS X:
$ brew install tomcat-native
==> tomcat-native
In order for tomcat's APR lifecycle listener to find this library, you'll
need to add it to java.library.path. This can be done by adding this line
to $CATALINA_HOME/bin/setenv.sh
CATALINA_OPTS="$CATALINA_OPTS -Djava.library.path=/usr/local/opt/tomcat-native/lib"
If $CATALINA_HOME/bin/setenv.sh doesn't exist, create it and make it executable.
Then add it to the eclipse's tomcat arguments (double-click Server > Open Launch Configuration > Arguments tab > VM arguments)
-Djava.library.path=/usr/local/opt/tomcat-native/lib
on debian 8 I fix it with installing libapr1-dev:
apt-get install libtcnative-1 libapr1-dev
Had this problem as well. If you do have the libraries, but still have this error, it may be a configuration error. Your server.xml may be missing the following line:
<Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
(Alternatively, it may be commented out). This <Listener>, like other listeners is a child of the top-level <Server>.
Without the <Listener> line, there's no attempt to load the APR library, so LD_LIBRARY_PATH and -Djava.library.path= settings are ignored.
I had this issue upgrading from Java 8 to 11. After adding this dependency, my app launched without issue:
<dependency>
<groupId>org.javassist</groupId>
<artifactId>javassist</artifactId>
<version>3.25.0-GA</version>
</dependency>
I had the same problem when tomсat could not find the class. Try to view other log files. Sometimes No class def found error appears in different log files:
tomcat8-stdout
tomcat8-stderr
localhost
If you don't have Tomcat Native library install it with:
sudo apt-get install libtcnative-1
and if it's still there an old version upgrade it with:
sudo apt-get upgrade libtcnative-1
My problem was in add some library from tomcat to eclipse class path i just going to
eclipse click right to project and going to debug configuration -> classpath -> Add External JARs add all jars files from apache-tomcat-7.0.35\bin this was my problem and it's worked for me .
For future readers:
I had faced this issue myself when trying to run a Spring Boot application in Spring STS. This issue didn't resurface initially. I was able to work on my project without any issues for quite some time until one fine day I started getting this particular error.
From what I am able to recall I had not made any configuration changes to my project and neither changed the Java/Tomcat version being used.
None of the discussions/suggestions regarding installing the tomcat native library made any sense to me since the project was already working fine before.
SOLUTION that worked for me:
So lastly I though of trying to delete and reimport my project.
I deleted my project from Spring STS, restarted the Spring STS and then reimported the project. It worked like a charm and never faced the issue ever since.
You may also try deleting any IDE generated files/folders(if there are any) in your project, before restarting the IDE and reimporting the project.
I still happen to work on this project from time to time and haven't faced the issue as of now. My current development IDE is IntelliJ.
I'm not sure if the error was IDE specific.
I'm trying to install NetBeans on Linux Mint, and I'm getting the following error every time I run the installation script:
Configuring the installer...
Searching for JVM on the system...
Extracting installation data...
Running the installer wizard...
Can`t initialize UI
Running in headless mode
What should I do to get it working?
In case anyone has this problem in the future, Netbeans doesn't like OpenJDK 6 but -- fortunately -- it works fine with OpenJDK 7 (as expected as for Java 7 OpenJDK is the reference implementation). Just make sure you remove any Java 6 packages before installation attempts. On Ubuntu and Mint one can do:
sudo apt-get purge ^openjdk-6-*
sudo apt-get install openjdk-7-jdk
It should work afterwards.
Looks like Netbeans does not work properly with Openjdk. This is what I did (in Linux Mint 12):
sudo apt-get remove openjdk*
sudo apt-get install sun-java6-jdk
Then you will be able to run the .sh installer as usual.
I hit this same issue on Kubuntu 12.04 LTS but needed Sun JDK 6 for a project I'm maintaining. I stumbled upon Martin Wimpress' OAB-Java script (by way of help.ubuntu.com) which creates and installs a local apt repository for Sun JDK 6. You can find the latest instructions on Martin's github site which run as follows:
cd ~/
wget https://github.com/flexiondotorg/oab-java6/raw/0.2.7/oab-java.sh \
-O oab-java.sh
chmod +x oab-java.sh
sudo ./oab-java.sh
If you want to see what this script is doing while it is running then execute the following from another shell:
tail -f ./oab-java.sh.log
Alternatively, you can clone the OAB-Java repo and kick of the script from within it:
git clone git://github.com/flexiondotorg/oab-java6.git
cd oab-java6
sudo ./oab-java.sh
Either way, once that is in place follow Jose's instructions to remove openjdk and install sun jdk:
sudo apt-get remove openjdk*
sudo apt-get install sun-java6-jdk
One final note, the script accepts a -7 argument which will create and install a local apt repository for Oracle JDK 7 should you want to go that route.
I was able to get it to work by getting into the target system using ssh -X, then making sure DISPLAY was exported. That handles the X server issues.
Change the priority of the Oracle Java executables:
export PATH=/usr/java/latest/bin:$PATH
Run the installer:
./netbeans-8.1-linux.sh
What worked for me was installing default java environment from the terminal:
sudo apt-get install default-jre
The installation was a success - under "user".
The installation failed - under "su" (under Red Hat equivalent of "sudo"). With
Can`t initialize UI
Running in headless mode
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
For me.
The error I'm getting with the thinking-sphinx 2.1.0 gem is:
Sphinx cannot be found on your system. You may need to configure the following
settings in your config/sphinx.yml file:
* bin_path
* searchd_binary_name
* indexer_binary_name
sh: searchd: command not found
Failed to start searchd daemon. Check /var/log/searchd.log.
Failed to start searchd daemon. Check /var/log/searchd.log
Be sure to run thinking_sphinx:index before thinking_sphinx:start
Search log is empty
and when I try to manually run rake task from bash I get:
rake aborted!
Unable to activate thinking-sphinx-2.0.10, because activerecord-2.3.9 conflicts with activerecord (>= 3.0.3)
activerecord 3.0.3 downloaded with the thinking-sphinx gem 2.0.9 automatically.
I have tried almost every version of thinking sphinx and sphinx and just get various errors with every attempt.
Sphinx runs great from a bash command line, but no go from the rake tasks. I have tried the plugin, but that just throws a different set of errors. I am hoping someone knows of a combination of rails / riddle / thinking-sphinx and or sphinx versions on mac lion, if mac version even matters.
And my current conf is as follows:
development:
bin_path: /usr/local/Cellar/sphinx/0.9.9/bin
searchd_binary_name: searchd
indexer_binary_name: indexer
enable_star: true

Thanks much in advance for any advice.
Answered this on the mailing list as well, but just for others who come across it - 1.4.10 is the right version of TS to use (the 2.x releases of Thinking Sphinx are for Rails 3.x).
