You need the servlet Jar in your classpath or use a more recent version of axis.
NOTE: AXIS 1.0 version even on client side needs servlet JAR file or you get this exception:
(upcoming 1.1 version should have this fixed)

Had similar problem with desktop application. In Netbeans this appeared suddenly, though I was changing only unrelated sql queries. Problematic packages were still in my main package, though couldn't be found.
Solved renaming problematic classes in my main package (and renaming back, if needed). Also corrected naming standard deviations (some class names first letters were low-case).

I've used 'net.schmizz.sshj.SSHClient' package to connect to a server.
Below is my code:
public class ConnectToServer {
String hostName = "10.250.176.6";
int port = 22;
public ConnectToServer(String hostName, int port) {
this.hostName = hostName;
this.port = port;
}
public void ssh() {
SSHClient ssh = new SSHClient();
String cmd = "ipconfig";
try {
ssh.connect(this.hostName, this.port);
ssh.isConnected();
final Process process = Runtime.getRuntime().exec(cmd);
ssh.disconnect();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
However, I faced to an error: "Exception in thread "reader" java.lang.NoClassDefFoundError: org/bouncycastle/crypto/ec/CustomNamedCurves".
I added bcprov-jdk15on-1.49 and bouncycastle.jar into my classpath.
Please help me to resolve this error.

Your jar is probably missing its dependencies (or some of it.) If its a maven project i suggest you rather switch to Maven.
A nice tutorial can be found here: Maven in 5 Minutes
I think, the SSH Client is missing org.Bouncycastle.crypto as libary (dependency). Quick way to fix this is to get the jar for it too.
This issue might be occurred due to use of different versions of bouncycastle jars in the project.
the solution is ,
to find the different versions of bouncycastle jars getting used directly or indirectly in the project.
try to use one version of bouncycastle jars in whole project.
make changes according to version which you have chosen to use across project as code written with one version of bouncycastle jar may not work for other version of bouncycastle.
Clean your project or rebuild it again.
If the problem is not solved, please post complete exception so that we will get more clarity.

Web-service client initialisation comes out with no any errors -
URL service_endpoint;
service_endpoint = new URL(endpoint);
service = new UDHandlersServiceImpl(service_endpoint, SERVICE_QNAME).getUDHandlersServiceImplPort();
NullPointerException occurs after calling any method of "service". And it doesn't even reach server side - because it doesn't have any logs there. Furthermore - such situation occurs only on the WebSphere - we deployed our client application on the Tomcat (server remained on websphere) and it worked fine. One more thing - SoapUI does not have any problems interacting with server side too.
We tried to switch classLoadings to parentLast for client application - with no success.
Also I can't even find sources for "org.apache.axis2.jaxws.message.databinding.JAXBUtils.getJAXBContext(JAXBUtils.java:445)". I googled it and didn't find this version of JAXBUtils. But even if i did, i think, it wouldnt be useful...
I hope someone can help us with that unobvious problem.
Thanks beforehand.
===== updated======
When we remove jaxb libraries from endorsed dir (or appServer/classes) problem seems to disappear but in case of arising webExceptions(faults) server throws

and returns no answer to the client.
We've realized that our exceptions didn't contain 3 required methods -
//============required==================
public DocumentValidationException(String message, ErrorsBean errorsBean, Throwable cause) {
super(message, cause);
this.errorsBean = errorsBean;
}
public ErrorsBean getFaultInfo() {
return errorsBean;
}
public DocumentValidationException(String message, ErrorsBean errorsBean) {
super(message);
this.errorsBean = errorsBean;
}
//======================================
so, now it does.
And also we had some wrong target namespaces in it at the #WebFault annotations.
Here is the link with similar problem - https://www.ibm.com/developerworks/community/forums/html/topic?id=77777777-0000-0000-0000-000014076927#77777777-0000-0000-0000-000014083314
Since the java 7 update 25 launched by Oracle our application no longer functions.
Initially we got some warning about codebase & sercurity tags missing in the Manifest file, which we fixed.
The problem we now end up with is that in the Console we only get the following lines:
#### Java Web Start Error:
#### null
We also get an application Error dialog with the message: Unable to launch the application.
The details button gives the following details in the Exception:

desktop.DesktopProxySelector:
public class DesktopProxySelector extends ProxySelector {
public DesktopProxySelector(ProxySelector defaultSelector) {
URI httpsUri = new CentralConfigurationService().getCentralLocation();
(The last line is line number 24 where the exception occures)
Can someone give us some clues hints (or better a solution) for this new behaviour of java caused by this 'minor' update.
When we run the application straight from the cli using java -jar Desktop.jar the application wil run file, so the issue has clearly something todo with the changes in java web start.
#trashgod: the error clearly has something to do with the Permissions change in 7u25, since the NullPointerException occurs in com.sun.jnlp.JNLPClassLoader.getPermissions.
Just to explain what I think happens (I am a colleague of Wouter):
desktop.Main instantiates a desktop.DesktopProxySelector (our class),
desktop.DesktopProxySelector instantiates desktop.configuration.CentralConfigurationService
desktop.configuration.CentralConfigurationService instantiates a java.net.URI.
On the first line of the DesktopProxySelector init where the CentralConfigurationService is instantiated the getPermissions method, called by the JNLPClassLoader, throws the NullPointerException. So something is going wrong while loading the CentralConfigurationService class by java webstart with getting the permissions for the class. Could that have anything to do with the fact that a URI class is instantiated, which requires extra permissions (a connection to a remote uri is setup)?
Eventually the problem was solved.
The problem was caused between a mismatch in the included jar files in the main MANIFEST.MF file vs the jar files mentioned in the launch.jnlp.
Apperently it is now required to have all jar files that will be used also be present in the launch.jnlp file.
(In the past it was decided to keep this file manually in sink, which obviously was not always maintained in a propper way. Now this process is automated, so the problem should no longer happen to us.)
When I read a file from hdfs by giving it proper path the file is read successfully but when I try to use transform operator of jaql it throws an exception as given below and if I try to execute the code on JAQL shell then an exception is thrown of job.jar but even after adding the jar the exception is still thrown. if anybody knows that somehow JAQL is not configured properly with existing hadoop cluster or the exception is due to some other cause?
My code is:
jaql.setQueryString("read(lines('hdfs://hadoopserver:54310/dbreports/reports.json'," +
"{format: 'org.apache.hadoop.mapred.TextInputFormat',converter: 'com.ibm.jaql.io.hadoop.converter.FromJsonTextConverter'})) -> transform $.store_number;");
System.out.println("jaql running successfully....");
JsonValue jv = jaql.evaluate();
System.out.println("value is "+jv);
when run it throws an exception as:

Since few weeks we have some trouble with our external test environment (which is not operated by us). Our webapplication is connected to a soap webservice.
We are using:
metro 2.1.1 for the webservice client
java-1.5.0-ibm-1.5.0.12.4 is installed on the test environment.
tomcat version: 5.5.27
The first time trying to initialize the client on this environment, we are getting the following exception (only on this environment):

static {
Method tLoadMethod = null;
Method tIteratorMethod = null;
try {
Class<?> clazz = Class.forName("java.util.ServiceLoader");
tLoadMethod = clazz.getMethod("load", Class.class);
tIteratorMethod = clazz.getMethod("iterator");
} catch(ClassNotFoundException ce) {
// Running on Java SE 5
} catch(NoSuchMethodException ne) {
// Shouldn't happen
}
loadMethod = tLoadMethod;
iteratorMethod = tIteratorMethod;
}
It seems that instead of throwing an ClassNotFoundException the Classloader throws an SecurityException, which is not catched by the
static initializer.
What can be the cause of this behaviour (some policy settings?) and how can we prevent this. The application is running on our local test environment, and was running on the external environment too. The external provider denies any changes of the environment.
Is this behaviour IBM-JDK specific ?
EDIT:
I found the following in the JDK 5.0 API class java.security.SecureClassLoader :
SecurityException - if an attempt is made to add this class to a
package that contains classes that were signed by a different set of
certificates than this class, or if the class name begins with
"java.".
But souldn't this happen to all Metro clients running on tomcat ?
EDIT:
Thanks a lot for the advice! There is actually the path of a JDK 1.6 rt.jar in the classpath. And therefore the ServiceLoader class is found but not allowed to load within the Provider.
Thanks to Sean,
