I am trying to develop a GWT application that calls an existing (working) web service. I am using:
- JAX-WS RI 2.1.6 in JDK 6
- JDK 6
- Glassfish V3
- Eclipse 20110615-0604
I have tested my 3 component applications independently and they work fine:
1. GWT application - browser invoking GWT server side code. This is based on the GWT sample, http://code.google.com/webtoolkit/gettingstarted.html#create
2. Java application that uses JAX-WS proxy to invoke a Web Service. This is based on a JAX-WS hello world sample. I used wsimport on my wsdl to generate the proxy code.
3. Pre-existing Web Service, which I have the WSDL for.
When I merge the top 2 pieces of code, to create a GWT application that calls a web service from within the GWT server side code, my merged application fails with the exception below. I suspect some class conflict between the standard GWT dependencies and the standard JAX-WS dependencies.
I get the following exception:

I solved that by adding these lines to my code:
System.setProperty("javax.xml.transform.TransformerFactory","com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl");
Is there some other similar work around for the first exception.
Thanks,

It seems you're using an old Hibernate 3 in your application, which is not compatible with EAP 6.x. Use the Hibernate which is bundled within the EAP.
More, even if it was, your Hibernate library uses some alpha version of a library that I don't know: jboss-archive-browsing-5.0.0alpha-200607201-119.jar
Using alpha libraries in production is not a good idea in general.

I am using SUPER DEV MODE to run my existing project (built using GWT SDk 2.5.0).
Everything works fine,but only problem is that I am unable to make calls to my RPCs.I tried the solution i.e setting -Dgwt.codeserver.port=9876 in VM arguments,but still I am unable to call RPCs.It gives me following exception:-

Please provide me the solution to solve this problem.
Thanx well in advance..!!
-Dgwt.codeserver.port has only been introduced in GWT 2.6.
For older versions, you can manually copy the serialization policies from the CodeServer to your server hosting the servlets; or override doGetSerializationPolicy to load it via HTTP from the CodeServer (at http://localhost:9876/). Have a look at the code from a 2.6+ version of GWT for an example of how to do it.
…though honestly it's probably easier to just update to GWT 2.6.1 or, even better, 2.7.0.
Check your class com.lbtmind.appcore.client.ui.ActionMode.
Either it doesn't implement java.lang.Serializable or com.google.gwt.user.client.isSerializable
or it has no public no-arg constructor
or your widgetset needs to be recompiled
or you need to update the WEB-INF/lib/gwt-servlet.jar to the version you built with
I'm using the Simple XML API to serialize and deserialize XML data being sent from an Android app to a servlet.
The deserialization works fine on the android app. But when the same code is used on the servlet I get the following error:

I have made sure that the jar file has been imported in Eclipse. It has been checked mark under "Order and Export" tab of the "Properties" window.
Here is the code which works fine on Android but fails on the servlet:
Serializer serializer = new Persister();
File source = new File("/home/kk/workspace/testfile.xml");
Reg_info_xml parse_xml = serializer.read(Reg_info_xml.class, source);
String name = parse_xml.getUser_name();
System.out.print(name);
The class ins't in the server class path, so put your jar in the WEB-INF/lib folder of your project

Whenever you make an Rpc call, the classes involved must implement java.io.Serializable. In your case, this might have happened.
In your service class methods you somewhere mentioned one of the arguments or return type as java.io.FileNotFoundException which does not implement java.io.Serializable. Hence it cannot be serialized.
EDIT : This might help you Serialization Exception while making an RPC call
Every exception that could go to the client-side has to be declared in a throws clause in your RemoteService interface.
If it's working in DevMode, it's probably because you don't have such an exception. You have to find the cause of the FileNotFoundException.
I am using this tutorial to learn JavaEE web app. I am using eclipse indigo for Java EE, objectdb-2.4.2_02, glassfish 3.1.2 on windows xp. When I run the program, the embedded browser opens page with this status & printing javax.ejb.EJBException. I google it but I did not find an answer for this problem.

Only a partial answer...
The key issue is
Caused by: java.lang.IllegalStateException:
Unable to retrieve EntityManagerFactory for unitName null
Which means that it failed to figure out which PersistenceUnit it should use in GuestDAO. This might indicate that GF could not find your persistence.xml file in the project, please doublecheck whether the creation of persistence.xml as described went well and whether persistence.xml exists ONCE and ONLY ONCE in the deployed project (the once part is because I've noticed Eclipselink can get quite confused when confronted with multiple persistence.xml files in one project. If all that's OK add the unit's name to the #PersistenceContext annotation in GuestsDAO, as shown below
#PersistenceContext(unitName="GuestbookPU")
private EntityManager em;
If all of this fails let me know.
In my experience it is some kind of database connection problem. Best thing to do is to login to the server and PING the data base to see if it works.
