I am interested create an Client Interface for a simulation software. So I have downloaded Milo and I went through the examples. I was able to build successfully when I executed mvn clean package. I would like to know how to set the run configuration for executing the Client Example.java.
In the client-examples project. Look into the ClientExample.java source file. In this file
update the method getEndpointUrl for server Endpoints. By default this method has a loop back Endpoints i.e :"opc.tcp://localhost:12686/milo".

I am building a dropwizard service which will connect to multiple data sources including mySQL and Elasticsearch. All the mySQL settings can be defined in the yaml config file which gets read in after running from the commandline.
But what about other settings that I need to read in for other data sources that I will connect with myself, for example Elasticsearch? Where can I define those settings?
I thought I could add another commandline Command - which I tried, but I can only run a single command (from the commandline) at a time - so I can't seem to run both the 'server' command as well as my custom command, 'custom' which is followed by the my own config file for elasticsearch.
How can I introduce settings either individually or from a file - which are defined at run time (not hard coded)?
Thanks
Anton
Check out the Dropwizard Core documentation on adding custom configuration.
You'd create an ElasticSearchFactory class similar to the MessageQueueFactory in the example, reference this in your Configuration (that's in turn referenced in your Application), and then the options you need can be added to your main yaml configuration.
I want to add a hook to ejabbered code. Steps followed:
added mod_filter.erl to src folder(mod_filter catches filter_packet event and returns modified packet)
added mod_filter in ejjbaerd.yml under modules section.
ran ./configure, make , make install
Ejabberd server runs successfully , with mod_filter.beam file in /ebin folder but the ejabberd.yml file located at /etc/ejabberd/ejabberd.yml does not get updated as per my second step.
I can manually update it and restart server but that does not seem to be the correct way. I think i might be missing a deployment step here, please suggest.
Change configuration file (ejabberd.yml) according to your need and reload configuration file like that- ejabberd_ctl reload_config or ejabberd_config:reload_file(). or ejabberd_config:load_file("/etc/ejabberd/ejabberd.yml"). you do not need to restart server.

I would like to use the google spreadsheet connector at https://github.com/wso2/esb-connectors/tree/048e223c037b447c3f77c2b7e72338dc26ea5c46/googlespreadsheet. But it is not found in wso2 store. I would like to know how I can compile it and use the connector from github. Please help
Generally git wont allow you to get a folder. so you need to go with svn approach. follow bellow instruction as it is. (assumtion on you are woking in linux / mac enviorment. if not make the command the way works on windows.
create new directory where ever you want and navigate inside that
wget https://raw.githubusercontent.com/wso2/esb-connectors/048e223c037b447c3f77c2b7e72338dc26ea5c46/pom.xml
mkdir wso2
cd wso2
mkdir esbconnector
cd esbconnector/
mkdir googlespreadhseet
cd googlespreadhseet/
svn checkout https://github.com/wso2/esb-connectors/trunk/googlespreadsheet/googlespreadsheet-connector/googlespreadsheet-connector-2.0.0/org.wso2.carbon.connector
cd org.wso2.carbon.connector/
mvn clean install
it may take little time as its required to download few artifacts. if its ended up with error that integration test not found get the integration test Base from the same repo and build that first. then rebuild the connector
Recently Google spreadsheet Version2 connector has been created with REST API and added to WSO2 store. The Connector zip file can be downloaded from here. Go to the link and click the 'download connector' button and follow the documentation for the configuration.
You can checkout the connector source from the https://github.com/wso2/esb-connectors/blob/master/googlespreadsheet and built it.
Then add the connector to the ESB from the UI according to the https://docs.wso2.com/display/ESB481/Managing+Connectors+in+Your+ESB+Instance
I'm new in JAVA\Grails\Groovy. Just began to create simple apps.
I've got a task to create grails app that:
1) shows a list of source zip files on a remote server, that is available by FTP and SSH
2) shows a list of destination remote servers with predefined target folders, that are available only by SSH
3) after choosing source zip and dest server it copies zip to target server\folder and unzippes. Progress bar must be shown.
4) performs some additional commands, such as ls or something like that
All configurations must by either in config files or in the database.
No information should be hardcoded in app.
Please help me to choose approach, plugin or framework.
Any help would be appreciated
I've used JSch a lot for SCP file transfer and remote exec using SSH and works very well. You could use it directly like you would in a Java app, by adding a dependency for the jar in BuildConfig.groovy
compile 'com.jcraft:jsch:0.1.51'
but the most trivial Google search I could manage that included "Grails" and "SSH" tells me that there's this plugin which looks great, and this plugin which also looks great, and this blog post which looks great, and also this plugin which uses a different library but also looks great.
Those options cover the ssh and scp/sftp parts, and you can use the JDK support for Zip files, e.g. java.util.zip.ZipFile and the other related classes in that package, to unzip the files. The rest is pretty straightforward, but if you need more help ask more questions (one question per question).
I tried to run grailsw, but the wrapper cannot connect to download grails-2.2.1-download.zip (creates a 0 byte file instead).
I need to use a proxy server to connect to the internet, where do I configure proxy settings for the Grails Wrapper?
After running grails wrapper, your project directory has a new subdirectory called wrapper, with a file grails-wrapper.properties. You can configure your proxy settings in there, with the following properties:
systemProp.http.proxyHost=
systemProp.http.proxyPort=
systemProp.http.proxyUser=
systemProp.http.proxyPassword=
systemProp.http.nonProxyHosts=
I solved this problem for myself.
It is a two step process
1.a) Back up your JRE_HOME\lib\security folder. This is essential because the below steps might corrupt cacerts file under jre.
1.b) You need to install the ssl public key of Github.com to your local file system. To do that you have to use the InstallCert.java program( Link to InstallCert.java )
It is supposed to be run as java InstallCert github.com
and when it asks to enter cert number you need to enter 1
It will create a file with name "jssecacerts" in the current directory
1.c) But this program will not work because it does not know about how to authenticate with proxy. For this you need the code from SSLSocketClientWithTunneling page
Use the above two and create a program that tunnels through the proxy retrieves the ssl key and writes a file called jssecerts
2) Update your grails.bat with addtional options. Add these options to the %JAVA_EXE% command line. Paste them after %DEFAULT_JVM_OPTS%
-Dhttp.proxyHost=YourproxyURL -Dhttp.proxyPort=YourproxyPort -Dhttps.proxyHost=YourproxyURL -Dhttps.proxyPort=YourproxyPort -Dhttp.proxyUser=YourProxyUserID -Dhttp.proxyPassword=YourProxyPassword -Dhttps.proxyUser=YourProxyUserID -Dhttps.proxyPassword=YourProxyPassword -Djavax.net.ssl.trustStore=path-to-your-jssecacerts-created-in-step-1
