Re: File access from a .war
Hi,
Your post helped me - but in unexpected ways. :D
I just added this line:
private static final String PATH = "c:/primes.txt";
and used PATH instead getResourceAsStream() to my existing code and it worked. I guess it was a Java PATH issue. Thanks!On 7/12/06, Rodrigo Ruiz <

any case, it will be read-only (it is an InputStream).The ServletContext has a method to obtain an absolute path from acontext relative path. With that path you can create FileReaders andFileWriters without problem. I know you can get an instance of this

Re: File access from a .war
Hi,Thank you for the exhaustive list of alternatives. I just have one small problem: I meant an .aar archive that is used for Axis2 web service deployments in the services directory (I incorrectly wrote .war in the subject of the original email). Do the same concepts apply (some of them, such as DBMS for example, obviously do, but I was hinting more towards the exploded archive option)? On 7/10/06, Rodrigo Ruiz <[EMAIL PROTECTED]> wrote: Depending on the servlet container you are using, war archives may beconsidered read-only. In this case you will not be able to write a filewithin the application context.Some alternatives you have are: - Deploy your application as an "exploded war" (the exact name will varyfrom container to container). When deploying in this mode, your classescan write files at any location within your context. - Use an absolute path for your file. The path may be configured throughJNDI, or System properties, or you might put it into a subfolder of theuser home (this is very common in *nix environments).Other options imply to use a different storage type: - Use the User Preferences API to store the value. This API is availablestarting from Java 1.4.- Store it into the JNDI tree. This only works if the JNDIimplementation is writeable and persistent. For example, AFAIK, it will not work in Tomcat- Use a DBMS. It may seem an overkill solution, but there are some verylightweight databases there.

File access from a .war
Hi,I have a web service that is supposed to generate prime numbers. I store the latest generated prime number in a file called prime.txt. So for example, if the program is run and generated 3, 3 will be stored in prime.txt and next time it will generate 5. If there is no prime.txt, the program will generate 1 and try to create prime.txt. My problem is that my web service application does not seem to be able to read/write a file. Any ideas on how this should be done? Notice that the prime.txt must be able to saved for the duration of the web service's lifetime. Regards

Re: Axis2 / Axis RPC
Hi,
Well the problem with using Axis2 1.0 is that it generates an erroneus
WSDL. I tried to reproduce the guide at
http://www.wso2.net/tutorials/axis2/java/2006/05/29/hello-world.
According to that page and according to my experience, it creates an
erroneus WSDL which in turn, leads to java stubs that do not contain
inner classes (the author of the above page also points out the fact
that one should use nightly builds). In anycase, I have tried using a
nightly build axis2.war (so that the WSDL is correct) and Axis2 1.0
WSDL2Java (so that the stub generation is correct), but it doesnt work.
Im out of ideas. Anyone?

Re: Axis2 / Axis RPC
Hi, Basically what I'm trying to do is to create a simple Web Service that will receive a String and retun the same string, i.e. basically an "echo" web service. I tried using the sample on the Axis2 documentation page with OMElement - it works fine. My problem is that I want to use String instead of OMElement on both sides (server as well as client). Apparently, I cant do this unless I use the RPC So what I have is a services.xml that looks like this: -- operation> MyService2parameter > service> A MyService2.java that looks like this: public class MyService2 { public String echo(String echostring) { return echostring; } } I can deploy this using axis2.war on JBoss.

It does generate them, but when I try to run the client I get the following error: Exception in thread "main" java.lang.RuntimeException:java.lang.RuntimeException: Unexpected subelement returnat org.apache.axis2.MyService2Stub.fromOM(MyService2Stub.java:665)at org.apache.axis2.MyService2Stub.echo(MyService2Stub.java:144)at org.apache.axis2.Client.main(Client.java:16)Caused by: java.lang.RuntimeException: Unexpected subelement returnatorg.apache.axis2.MyService2Stub$EchoResponse$Factory.parse (MyService2Stub.java:419)at org.apache.axis2.MyService2Stub.fromOM(MyService2Stub.java:657)... 2 moreI googled this and this page ( http://mail-archives.apache.org/mod_mbox/ws-axis-dev/200605.mbox/[EMAIL PROTECTED]) claims that this error message appears because axis2 does not support RPC Bindings.I'm confused - how do I generate a client for this WSDL?
Re: Axis2 / Axis RPC
I tried to make my own by generating the stub files usingWSDL2Java from the WSDL generated by Axis.Everything seems fine, I deploy it, etc. but when I try to run the clientI get the following:
Exception in thread "main" java.lang.RuntimeException:java.lang.RuntimeException: Unexpected subelement returnat org.apache.axis2.MyService2Stub.fromOM(MyService2Stub.java:665)at org.apache.axis2.MyService2Stub.echo

http://mail-archives.apache.org/mod_mbox/ws-axis-dev/200605.mbox/[EMAIL PROTECTED]this is because axis does not support RPC bindings.

Axis2 / Axis RPC
Hi,
I am a newbie trying to create a RPC-based Web Service. I created this
using Axis2 (latest nightly build dated 5th July). The problem is that
I cannot use WSDL2Java to generate the Client stubs. So what I did is
to use the old Axis (1.4 from 22nd April) to do this.
For some reason I don't get it to work. My Client code looks like this:
package org.apache.ws.axis;
import javax.xml.namespace.*;
import javax.xml.rpc.*;
import java.rmi.*;
import java.net.*;
public class Client2 {
public Client2() {}
interface MyPrimeHandler extends Remote {
public String echo(String echostring) throws RemoteException;
}
public void invokeService() {
String msg = "Det funkar";
try {
String wsdlLoc
= "http://localhost:8080/axis2/services/MyService2?wsdl";
QName
serviceName = new
QName("http://localhost:8080/axis2/services/MyService2", "MyService2");
ServiceFactory sFactory = ServiceFactory.newInstance();
Service
service = sFactory.createService(new URL(wsdlLoc), serviceName);
MyPrimeHandler
mp = (MyPrimeHandler)service.getPort(MyPrimeHandler.class);
String resp = mp.echo(msg);
System.out.println(resp);
}
catch (Exception e) { e.printStackTrace();}
}
public static void main(String[] args) {
Client2 cl2 = new Client2();
cl2.invokeService();
}
}
The exception that I get is:
- Unable to find required classes (javax.activation.DataHandler and
javax.mail.internet.MimeMultipart). Attachment support is disabled.
javax.xml.rpc.ServiceException: Error processing WSDL document:
javax.xml.rpc.ServiceException: Error processing WSDL document:
javax.xml.rpc.ServiceException: Cannot find service: {http://localhost:8080/axis2/services/MyService2}MyService2

at org.apache.axis.client.ServiceFactory.createService(ServiceFactory.java:198)
at org.apache.ws.axis.Client2.invokeService(Client2.java:22)
at org.apache.ws.axis.Client2.main(Client2.java:33)
I have checked and the EPR exists at the specified URL above.
Does anyone have an idea on how I should solve this problem? Or am I
barking up the wrong tree? Perhaps there is some other way generating
client stubs with Axis2? Any help would be appreciated.

1.2rc2 (Wrapped) Document/Literal soap response for array items xmlns set to ""
Hi, It looks like AXIS 1.2 RC2 is sometimes incorrectly setting/including the xmlns="" attribute for child "item"s of array elements when using Document/Literal (Wrapped). My .NET cilent cannot deserialize the requestedAttributes (NamedValue[]) section of complex type Item correctly, yet can correctly deserialize the top-level loginReturn (which is also NamedValue[]). Is this bug http://issues.apache.org/jira/browse/AXIS-1547 thanks, Matt.

Re: Using .NET how to deserialize obj from detail element of SOAP fault sentby AXIS?
Hi All,
I switched the server over to utilize (Wrapped) Doc / Literal (using java2wsdl) and created new Web Reference in .NET.
Once I did this, I was able to successfully deserialize using XmlSerializer after I put in an XmlRootAttribute setting on the generated FdkException class.
For the life of me, I could not get the damn SoapFormatter to decode RPC/Encoded - kept complaining about missing top object or something along those lines.
For those curious, the code I used was:
FdkException fe = null;
XmlReader reader = null;
XmlWriter writer = null;
MemoryStream mem = new MemoryStream();
reader = new XmlNodeReader(se.Detail.FirstChild);
writer = new XmlTextWriter(mem, System.Text.Encoding.UTF8);
writer.WriteNode(reader,true);
writer.Flush();
mem.Position = 0;
XmlSerializer serializer = new XmlSerializer(typeof(FdkException));
fe = (FdkException) serializer.Deserialize(mem);
The crazy thing is that .NET was working perfectly with RPC / Encoded for everything other than my manual deserialization efforts.
It would seem Doc / Literal is the way of the future anyway.
thanks,
Matt.

RE: Using .NET how to deserialize obj from detail element of SOAP fault sentby AXIS?
Hi Dino,
Thanks for your reply.
Does .NET uses XMLSerializer behind the scenes to perform serialization/deserialization of SOAP messages?
If so, it seems to support these complex array types (defined in the same .WSDL file) fine - and I didn't do anything tricky to make this happen either. I just used the web reference tool to point to the WSDL file and woila!
For example, on a successful login, the server returns a loginResponse message that is defined as following:
Where: xmlns:impl="http://xmlns.mycompany.com/app/ws" and: xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"and: xmlns:xsd="http://www.w3.org/2001/XMLSchema"
In my code, the following works perfectly:
int sessionTimeout = -1, transactionTimeout = -1;Item user = null;NamedValue[] nvArray = null;try{ nvArray = rlManager.login(username,password);}catch(System.Web.Services.Protocols.SoapException e){ throw;}for (int i=0; i { switch (nvArray[i].name) { case WebServiceConstants.LOGIN_USER: if (!(nvArray[i].value is Item)) throw new exception.UnexpectedTypeException(WebServiceConstants.LOGIN_USER + " not an Item."); user = (Item) nvArray[i].value; if (user.type != ItemTypes.USER) throw new exception.UnexpectedTypeException(WebServiceConstants.LOGIN_USER + " not an Item of
type " + ItemTypes.USER); break; case WebServiceConstants.SESSION_TIMEOUT: if (!(nvArray[i].value is Int32)) throw new exception.UnexpectedTypeException(WebServiceConstants.SESSION_TIMEOUT + " not an Int32."); sessionTimeout = (Int32) nvArray[i].value; break; case WebServiceConstants.TRANSACTION_TIMEOUT: if (!(nvArray[i].value is Int32)) throw new exception.UnexpectedTypeException(WebServiceConstants.TRANSACTION_TIMEOUT + " not an Int32."); transactionTimeout = (Int32) nvArray[i].value; break;
default: break; }}if (user == null){ throw new exception.AccessDeniedException();}
Is there an alternative preferred/standard mechanism to define array types in the WSDL?
Assuming I was not using the funky array stuff, and just trying to deserialize a standard object with xsd string/int attributes etc by using the detail element inside a SoapException, do you know how you would go about doing this?
many thanks,
Matt.

Using .NET how to deserialize obj from detail element of SOAP fault sentby AXIS?
Hello,
I'm trying to build a C# client to consume an AXIS Web Service (running SOAP over HTTP). The Web Service encodes full server-side exception traces in the Soap Fault > Detail element using complex type structures declared in the WSDL file.
I have had absolutely no luck working out how I can deserialize the custom server exception object out of the detail element using .NET (C#). I' wondering if anyone in the AXIS community has done this before?
I have tried both SoapFormatter, and XmlSerializer with absolutely no luck.
try
{
e.g. login operation
}
catch (System.Web.Services.Protocols.SoapException e)
{
XmlReader reader = null;
XmlWriter writer = null;
MemoryStream mem = new MemoryStream();
FdkException fe = null;
try
{
reader = new XmlNodeReader(e.Detail.FirstChild);
writer = new XmlTextWriter(mem, System.Text.Encoding.UTF8);
writer.WriteNode(reader,true);
writer.Flush();
mem.Position = 0;
Add deserialization code here
fe = (FdkException)
}
catch (Exception ex)
{
System.Console.WriteLine(ex.toString());
throw;
}
}
The first deserialization mechansim I tried was using System.Runtime.Serialization.Formatters.Soap.SoapFormatter
SoapFormatter sf = new SoapFormatter();
sf.Binder = new FdkExceptionDeserializationBinder();
fe = (FdkException) sf.Deserialize(mem);
With FdkExceptionDeserializationBinder.cs looking like the following:
public class FdkExceptionDeserializationBinder : System.Runtime.Serialization.SerializationBinder
{
public override Type BindToType(string assemblyName, string typeName)
{
if (assemblyName.Equals("http://xmlns.mycompany.com/app/ws"))
{
switch (typeName)
{
case "FdkException" : return typeof(FdkException); break;
case "ArrayOfFdkExceptionEntry" : return typeof(FdkExceptionEntry[]); break;
}
}
return Type.GetType(String.Format("{0}, {1}", typeName, assemblyName));
}
}
This deserialization approach resulted in an exception:
Exception Type: System.Runtime.Serialization.SerializationException
Message: No Top Object
Source: System.Runtime.Serialization.Formatters.Soap
The second deserialization mechanism I tried was using XmlSerializer:
XmlTypeMapping myMapping = (new SoapReflectionImporter().ImportTypeMapping(typeof(FdkException)));
XmlSerializer serializer = new XmlSerializer(myMapping);
fe = (FdkException) serializer.Deserialize(mem);
I set Soap options in the FdkException class:
using System;
using System.Xml.Serialization;
...
[Serializable]
[SoapTypeAttribute(Namespace="http://xmlns.mycompany.com/app/ws", TypeName=fault)]
public class FdkException
{
public string errorCode;
public FdkExceptionEntry[] exceptionEntries;
public string serverStackTraceId;
}
using System;
using System.Xml.Serialization;
[Serializable]
[SoapTypeAttribute(Namespace="http://xmlns.mycompany.com/app/ws", TypeName=FdkExceptionEntry)]
public class FdkExceptionEntry
{
public string errorCode;
public long id;
public string serverStackTraceId;
}
I got the following exception:
Message: There is an error in XML Document (1,541).
Exception Type: System.InvalidOperationException
Source: System.Xml
Inner Exception:
Message: Cannot assign object of type System.Xml.XmlNode[] to an object of type FdkException
Exception Type: System.InvalidCastException
Below is the SOAP message returned from the server on an invalid logon attempt (including Fault):-
soapenv:Server.userException
AccessDenied
AccessDenied - Invalid Credentials
Below is relevant pieces of the WSDL file relating to the FdkException object:
Has anyone out there been able to deserialize from SOAP fault detail element using C#?
