Are you running Selenium IDE or RC?
If Selenium RC, then I have noticed this kind of exception when the instance is not correctly created e.g. you need:
selenium = new DefaultSelenium ( ... )
selenium.start ();
selenium.open ( ... )
I've notice that this exception is thrown when selenium client tries to execute actions against a Selenium RC which browser have been closed.
Selenium RC assigns a session ID for each client as you can see in this excellent post: http://www.touspassagers.com/2010/11/exposing-the-selenium-browser-session-id/
Cheers, Daniel
Run this script in browser
http://localhost:4444/selenium-server/driver/?cmd=shutDownSeleniumServer
Actually selenium RC takes port: 4444 as default. Sometime program gets interrupted before executing tearDown(or closing the port).
That errors comes if the selenium server is not started. You have to start server.
And then execute the statement selenium.start();.

I was running the “NullPointerException”: null while executing the ‘Strings to Document’ node. I went through a discussion that has already taken place in the forum- Strings To Document - NullPointerException - #11 by natanaeldgsantos
But I could not find a satisfactory solution there. I have the updated version of KNIME (version 4.5.2) and there are no more updates. Interestingly one of my friends who has worked on the same dataset on the same version of KNIME is not facing any such issues.
Please guide me if there is any other way I can fix the error.

We started having a broken pipe issue this past Saturday with a job that gets run via a quartz scheduler during the early morning of each day. Below are some details on this.
The job consists of a native java class that calls Talend based jobs. Each of these Talend based jobs are getting the broken pipe error. Curious enough, when I run the same java class that gets submitted via the scheduler, no errors get thrown and the jobs run successfully. Also, this job stream runs in Tomcat.
Is there something I should do within the Talend jobs to see if a connection is available first? As you will see in the following jdbc parameters used for the tMysqlConnection component, the autoreconnect option is set to on.
jdbc parameters are as follows are "noDatetimeStringSync=true&connectTimeout=0&socketTimeout=0&autoReconnect=true"
Below is the stacktrace from this morning's job failure.
Any input is greatly appreciated. Thank you.
Exception in component tMysqlConnection_1
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 344,265,715 milliseconds ago. The last packet sent successfully to the server was 344,265,792 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

Finally got to the bottom of the broken pipe error I encountered.
The broken pipe error was being thrown due to my not closing down certain database connections
from within the Talend jobs. These connections at issue were connections that were defined in native
java (via the tJava component). It was incorrectly assumed by me that by referencing a previously
defined connection (for connection attributes), the connection resources would be closed and
released.
With the above in mind, I was actually creating a new connection as listed below and had to
specifically commit the connection and then close it out. The item to take note of here is the use
of the commit on the connection. The broken pipe error was still being thrown with just the close
of the connection. It was not until the commit was added did the broken pipe errors cease and that
was due to the connection being closed properly.
Hindsight being what it is... when using the Talend components (and not native java code) for
the connection definition and closing of that connection, the autoCommit feature is available to the
tMysqlCOnnection as well as the commit option being available for the close connection option being
available on the tMysqlCommit component. These two options allow for the prevention of a broken
pipe error and is why I only encountered broken pipe errors with the connections used by the tJava
components. Makes sense now.
// code snippet from the tJava component using native java to read a table.
java.sql.Connection tableConnection = null;
tableConnection = (java.sql.Connection) globalMap.get("conn_tMysqlConnection_1");
Statement selectStatement = tableConnection.createStatement();
// Execute statement to get the row count from the table.
ResultSet resultSet = selectStatement.executeQuery("select count(*) from tableA");
// Position the result set to allow for access of its information.
resultSet.next();
// Get the row count from the result set.
context.numberOfRows = resultSet.getInt(1);
resultSet.close();
selectStatement.close();
tableConnection.commit();
tableConnection.close();
And... I would be remiss if I did not mention that I found out about needing to use the commit
by an article on the following link. http://mikeschubert.com/2006/08/03/javanetsocketex/
I got a WAR-file for a working webservice, which accesses MySQL through JDBC hosted in TomCat 7.
Code:
private static final String db_jdbc_connection = "jdbc:mysql://localhost:3306/jsea";
Class.forName("com.mysql.jdbc.Driver");
con = DriverManager.getConnection(db_jdbc_connection, "root, "secret");
However, this causes the following error:
No suitable driver found for jdbc:mysql://localhost:3306/jsea

In the web-inf/LIB folder of the webservice the following JAR-file is present:
mysql-connector-java-5.1.23-bin.jar
Also tried copying this file to tomcat/lib folder.
MySQL is configured with database jsea and the users provided in the connection have permissions.
In MySQL log I see no entries at all.
I have Googled for hours now and I have really no clue. What am I doing wrong ?
No suitable driver" usually means that the JDBC URL you've supplied to connect has incorrect syntax or when the driver isn't loaded at all.
When the method getConnection is called, the DriverManager will attempt to locate a suitable driver from amongst those loaded at initialization and those loaded explicitly using the same classloader as the current applet or application.(using Class.forName())
I would suggest to place mysql-connector-java-5.1.23-bin.jar at /WEB-INF/lib directory of your project and restart Tomcat. Also, Check Tomcat logs, you should find something unusual.
I really have no idea what has caused the problem. I have received the source code of the webservice, cleaned the project, rebuilt, and it suddenly works....
I am trying to integrate SoapUI into my preexisting JUnit tests. I have created a test in SoapUI 3.6.1. It works.
My next step is to apply it to my development environment. In my Eclipse project I have added the jar to my classpath. I also created the following test.
public class TestMySoapUICase
{
#Test
public void testCase() throws Exception
{
SoapUITestCaseRunner runner = new SoapUITestCaseRunner();
runner.setProjectFile( "test/java/com/path/Test-soapui-project.xml" );
runner.run();
}
}
This test seems pretty trivial, but I am getting the following exception when running the test as a JUnit test:

It seems there are other people out there who have had this issue when running the application. Their solution was to set JAVA_HOME to point at jre6 instead of jre5. I tried this (not expecting it to work) and, well, was correct; it change nothing.
Does anybody out there have a solution to this issue?
Add soapui_folder/lib (where so soapui_folder - path to directory with unpacked soapui app) to classpath of your project and you set to go!
WBR
you need to add the commons-cli-1.2.jar file in this project after you also need to add the log4j 1.2.jar
I'm not that new to Java. I've done plenty of stuff with it before. But I'm migrating from PHP to Java Servlet/JSP (which I am new to) and I can't figure out this error to save my life. I installed Tomcat6 using Ubuntu 9.04's Synaptic Package Manager and it works like a charm. But when I put struts in my WEB-INF/lib directory and try to make a struts app, I get the below in the log file.
I used the struts-blank.war to start the project, so the web.xml is the same as provided in struts 2.1.8.1.
It appears that there is some issue with reading the struts-default.xml file.
Thanks in advance

I had a brain storm and figured this out myself. Although I don't think this is the most secure solution, but it works for my purposes and I'm not that concerned because it's a local dev server that only listens on the loopback interface (127.0.0.1).
Anyway, the solution is to add this to the bottom of /etc/tomcat6/policy.d/50local.policy
grant codeBase "file:${catalina.base}/webapps/-" {
permission java.security.AllPermission;
};
