javax.xml.ws.WebServiceException: Undefined port type Java Struts SOAP WSDL

ok I have really a strange problem that I keep looking for solution in google and yahoo for almost 4 hours today. And I desperately looking for a solution.
public static String [] checkCardAccount(String cardNumber, String cardIssuer, String securityNumber){
URL url = null;
try {
url = new URL("http://localhost:8999/bankcard?wsdl");
} catch (MalformedURLException e) {
e.printStackTrace();
}
QName qname = new QName("http://server.bcard.soap.com/","BankCardImplService");
Service service = Service.create(url,qname);
BankCard bankcard = service.getPort(BankCard.class);
return bankcard.getCardClientData(cardNumber, cardIssuer);
}
the above code is my client for accessing the SOAP service, it really works in a standalone java application but when I embed it to my Java Struts application it says the following error below
javax.xml.ws.WebServiceException: Undefined port type:

Now I really see that the problem is the target namespace because as I change it the error changes to that it says that the valid services is {http://bankcard.api.com/}BankCard
where I went wrong? this code works on standalone on Java Application but not in my Java Struts web app

give endpointIneterface in #WebService annotation in the implementation class, if you dont give endpoint interface, you have to mention fully qualified port name while using getPort method.
service.getPort("PortQName",BankCard.class);

You need to annotate the BankCardImpl class with #WebService(name="BankCard")
You can then use service.getPort(BankCard.class);
OR
If you just annotate it with #WebService or have given it another name, then you will need to provide more information to the getPort() method:
replace
BankCard bankcard = service.getPort(BankCard.class);
with
QName port_name = new QName("http://server.bcard.soap.com/","BankCardImplPort");
BankCard bankcard = service.getPort(port_name, BankCard.class);

Error while initializing metro webservice client

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):

at java.lang.J9VMInternals.initialize(J9VMInternals.java:134)
at javax.xml.ws.Service.<init>(Service.java:57)
...
It seems that there are some security issues within the metro Provider class.
I think the following snipped of the class javax.xml.ws.spi.Provider of metro is the source of the failure:
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,
There actually was 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.

Servlet using Datanucleus JDO can't find MySQL Driver

I'm trying to get JDO working within a Servlet; just a simple, basic Servlet. I know that a Servlet can connect to my db because a non-JDO servlet does it fine, and prints out data from the db (the following is at the start of a simple Servlet):
StringBuilder sb = new StringBuilder();
Connection conn = null;
try {
String userName = "jdo";
String password = "jdo";
String url = "jdbc:mysql://192.168.2.203:3306/jdo";
Class.forName( "com.mysql.jdbc.Driver" ).newInstance();
conn = DriverManager.getConnection( url, userName, password );
sb.append( "Database connection established" );
Statement s = conn.createStatement();
s.executeQuery( "select id, make, model from car limit 1" );
ResultSet rs = s.getResultSet();
while ( rs.next() ) {
int id = rs.getInt( "id" );
String make = rs.getString( "make" );
String model = rs.getString( "model" );
sb.append( "id = " + id + ", make = " + make + ", model = " + model + "\n" );
}
rs.close();
s.close();
}
That's all fine, the StringBuilder gets the data from the db appended no problem. What doesn't work, however, is the following. It throws a stack trace at the last line (line 28) I'm about to paste in here (this code is also at the start of a simple Servlet, just a different Servlet to the one that contained the previous code):
Properties p = new Properties();
p.setProperty( "javax.jdo.option.ConnectionDriverName", "com.mysql.jdbc.Driver" );
p.setProperty( "javax.jdo.option.ConnectionURL", "jdbc:mysql://192.168.2.203:3306/jdo" );
p.setProperty( "javax.jdo.option.ConnectionUserName", "jdo" );
p.setProperty( "javax.jdo.option.ConnectionPassword", "jdo" );
PersistenceManagerFactory pmf = JDOHelper.getPersistenceManagerFactory( p ); // this is line 28
The stack trace is at the bottom of this post, as it's rather long.
These two Servlets exist in the same war file, within which is the MySQL Connector/J jar file:
mkns#squeeze:~/workspace/JdoServlet$ jar tf dist/jdoservlet.war | grep mysql
WEB-INF/lib/mysql-connector-java-5.1.6.jar
I'm baffled as to why the DataNucleus libs are not finding the MySQL Connector/J driver jar file? I may be missing the obvious here, but I've stripped my Servlets back as much as I can to see where the problem is (as above) and I can't figure out where I'm going wrong. Can anyone point out the mistake I'm making?
I'm using the latest version of DataNucleus, 3.0.9.
--- 8< ---
And now the stack trace; this is the full stack trace taken from the Tomcat6 catalina log file. Note that the lines from my app are in the masked out package name of com.xxxxxxxxxx.jdoservlet.*, so if you look for that, you can identify where the exception was thrown by my app.

I had the exact same error except it was for the postgres jdbc driver on tomcat7 on a machine running ubuntu 12.04. I ended up taking the jdbc driver out of the war file and put it into /usr/share/tomcat7/lib/. This is a folder that tomcat looks for jar files.
This solution may not be for everyone as the jdbc driver will now be accessible to all servlets in all tomcat containers.

First thing: You typically omit the call to newInstance after the Class.forName call to load the database driver.
Second: DataNucleus prefers sometimes its own configuration. Have you tried to set the following properties according to the DataNucleus website?
datanucleus.ConnectionDriverName=com.mysql.jdbc.Driver
datanucleus.ConnectionURL=jdbc:mysql://'host':'port'/'db-name'
datanucleus.ConnectionUserName='user-name'
datanucleus.ConnectionPassword='password'
http://www.datanucleus.org/products/datanucleus/rdbms/support.html
Furthermore check that the driver was successfully deployed.
Does putting the jar in the directory specified in this question help?

I/O Socket error (Java)

I have a problem using a socket:
socket = new Socket(hostname, port);
os = socket.getOutputStream();
oos = new ObjectOutputStream(os);
is = socket.getInputStream();
ois = new ObjectInputStream(is); // THIS ALWAYS RAISES EXCEPTION
I have checked "is" is not null (with println):
java.net.SocketInputStream#403a7c5e
The IOexception message is: null

Does anybody know what is going on? Thanks.
EDIT: The object is an ObjectInputStream

My first guess is that the input stream you're getting is not a valid object stream. An ObjectInputStream is recognized by a particular stream header.
The important thing though is not only to understand this exception, but to learn how to analyze exceptions and failures. I suggest the following:
Examine your program's output (log files or console). See if it shows the exact type of exception and the full stack trace.
Use a debugger. Put a breakpoint at the problematic line, stop there with a debugger, and then step into the code until you get to the exception.
EDIT:
The stack trace shows that the ObjectInputStream tries to read a short value from the input stream, but the stream doesn't have any more data in it. Sounds like the server isn't sending the data you're expecting. (Or it simply isn't sending any data at all.)
In order to analyze the data you're receiving from the socket, you can temporarily change the code so that it reads from the input stream and dumps the contents (e.g. to System.out). Or you can use a network sniffer (such as Wireshark) that will show you all the network traffic between your machine and the server.

To expand on Eli's answer a bit, the input stream is not only not a valid ObjectInputStream produced by an ObjectOutputStream at the peer, it is also empty. The peer has closed the connection without instantiating an ObjectOutputStream on it at all, or doing any I/O whatsoever.

Axis 2 generated code in "Expanded Mode"

I'm having some problems understanding how to send a request to a web service that I have deployed. I have followed the following tutorial:
http://wso2.org/library/1719
Which I have successfully applied, and it worked well. The tutorial was straightforward, and I have easily generated a web service client. All I did was creating "request" objects from the exposed web service method, set its arguments, and then using the web service stub, I have passed the request object to the exposed web service method, and got a response.
Now, I have received a WSDL file from which I'm supposed to build a web service client as well. The problem is that the generated files from the WSDL differ greatly from that of the tutorial I followed. I learned later on that when generating clients using ADB, there is a mode called "Expanded Mode" that generates " a class for each of the outer elements and the named complex types " (http://axis.apache.org/axis2/java/core/docs/adb/adb-howto.html#gen_modes). The problem is that I'm unable to understand how to create a request object and get a response from the web service from the generated classes. My best shot was as follows:
GetMfrInventoryProductItemsListE wrapper = new GetMfrInventoryProductItemsListE();
GetMfrInventoryProductItemsList request = new GetMfrInventoryProductItemsList();
request.setArg0(deviceId);
request.setArg1(macAddresses);
request.setArg2(mfrKey);
wrapper.setGetMfrInventoryProductItemsList(request);
GetMfrInventoryProductItemsListResponseE wrapperResponse = wmService.getMfrInventoryProductItemsList(wrapper);
GetMfrInventoryProductItemsListResponse response = wrapperResponse.getGetMfrInventoryProductItemsListResponse();
return response.get_return();
In the above code getGetMfrInventoryProductItemsList is the name of my exposed web service method, and wmService is my stub.
The result was the following stack Trace :

After trying to debug the problem, I have found out that this is the line that is throwing the exception:
GetMfrInventoryProductItemsListResponseE wrapperResponse = wmService.getMfrInventoryProductItemsList(wrapper);
I just want you guys to tell me if the way I'm using the request/response objects is correct.Your help is much appreciated.

Finally, I figured out how to solve the problem. Apparently the web service call that I was making, was taking a lot of time that it was timing out as the stack trace shows. So I added the following to my code to the section where I was instantiating my client stub:
wmService = new WMServiceStub();
Options options = new Options();
EndpointReference epr = new EndpointReference(url);
options.setTo(epr);
options.setProperty(HTTPConstants.SO_TIMEOUT, new Integer(300000));
wmService._getServiceClient().setOptions(options);
This results in increasing the Axis 2 web services' socket timeout to 5 minutes, which should be more than enough to most web service calls. I hope that this will be helpful for some developers out there.
