Any help?
try the following :
1) run sudo ldconfig and check if that works.
if above does not works
2) open the file /etc/ld.so.conf.d/opencv.conf and insert the following in it
/usr/local/opencv/
then type: sudo ldconfig
if you can't find opencv.conf try locate opencv.conf to find it in your system

This question already has an answer here:
Is it necessary/important to set a classpath in the RMI registry?
(1 answer)
Closed 8 years ago.
I am trying lo learn RMI by following the Oracle documentation for RMI
I have created the classes for server side and client side, the class details are as follows:
compute.Compute -- Remote interface
compute.Task -- Normal interface
engine.ComputeEngine -- Class that implements remote interface
The code details can be seem from the document at these links:
http://docs.oracle.com/javase/tutorial/rmi/designing.html
http://docs.oracle.com/javase/tutorial/rmi/implementing.html
I have followed the steps given in below link to compile the code, all I am doing these are on my machine which has Ubuntu OS.
http://docs.oracle.com/javase/tutorial/rmi/compiling.html
Now as per below link I have placed the policy files for client and server at path : /home/user/public_html
http://docs.oracle.com/javase/tutorial/rmi/running.html
one more difference is I have tomcat server so I placed the class files under Tomcat webapps and under my web application, so I am running the class using the command:
java -cp /home/user/src:. -Djava.rmi.server.codebase=http://myipaddress:8080/myapp/classes/compute.jar -Djava.rmi.server.hostname=myipaddress -Djava.security.policy=server.policy engine.ComputeEngine
Now when I run this application I am getting exception as:
ComputeEngine exception:
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
java.lang.ClassNotFoundException: compute.Compute

The exception says java.lang.ClassNotFoundException: compute.Compute. But I have the class file in compute.jar that is located at my path /home/user/src and also I can download it using URL at http://myipaddress:8080/myapp/classes/compute.jar
Also FYI, I am doing all the steps on my machine only without any separate client and server machines.
Can someone please help me how can I fix this issue? Please let me know if you need any further details so I can provide them.
Update:
I followed the asnwer given by #EJP at this post - Is it necessary/important to set a classpath in the RMI registry?
then I started rmiregistry from directory where I have the jar file that has Compute.class and then ran the below command:
java -cp /home/user/src:/home/user/public_html/classes/compute.jar -Djava.rmi.server.codebase=http://myipaddress:8080/myapp/classes/compute.jar -Djava.rmi.server.hostname=myipaddress -Djava.security.policy=server.policy engine.ComputeEngine
But still I am getting same exception.
That class isn't on the Registry's CLASSPATH.
I encounter the following error when trying to connect to a database using SQuirreLSQL.

I also tried to check Driver Properties and the following error is displayed :
Loading JDBC driver "Microsoft MSSQL Server JDBC Driver" failed.
Can not load driver properties tab.
You need to copy driver into squirrel-sql/lib folder.
I've had same issue with MySql driver.
After copied drived into:
$HOME/squirrel-sql-3.7/lib/mysql-connector-java-3.0.17-ga-bin.jar
and restart Squirrel - there was no error anymore.
I have application in /var/lib/tomcat7/webapps/code I have init.java file that use json-rpc-2.0
I compile it using:
export CLASSPATH=$CLASSPATH:/path/jsonrpc2-base-1.35.jar:/path/json-smart-1.2.jar
javac init.java
it compile but when I run the app (not the servlet) I got error 404 from Tomcat and in catalina.out file there is exception:

with caused by not found com/thetransactioncompany/jsonrpc2/JSONRPC2ParseException which is in jar file.
What's happening here? How can I fix it to make it work?
This is usually the jar files are not available for Tomcat.
The best way to solve this is place the json-rpc-2.0 jar files into your Tomcat's lib folder
Update
As specified by A4L user , you can also put the jar in your web applications WEB-INF/lib as well.
