Hello,

I just started to know Wordnet. I installed it, and with the JWI library, wrote a little class able to return the synonyms, in English, of a given word.
Great!

However, I want more than that. I wish to be able to obtain something like this: the synomims for the word "X" in the language "Y".

I searched information about it. I found a very interesting website which can be part of the answer: OpenMultilingualWordnet

In this website, it is possible to get data files (TAB and LMF files) with the information in several languages (one file per language).

The problem is that I don't know how to use these files? Is there any way to integrate/add these files to wordnet? Is there a Java API able to access and interpret TAB/LMF files like JWI interpret Wordnet files?

Is there any other solution that I am not thinking on to achieve my goal?

Thanks,

Best regards.

Hello,

I developped a Java application with a given structure: a directory containing a .exe file, other configuration files and other subdirectories.

I would like to build a setup.exe installation file for my application. I already used InstallAnywhere some years ago which was very good.

However I would like to find now a similar program but FREE (if the possibility to install the setup file in both windows and Unix environments, better!).

Any suggestion?

Thanks for the help.

Best regards.

Hello

I developed a little web service using eclipse + JAX WS. I use it to validate the structure of a XML document. When I deploy the web service directly under tomcat, it runs fine and I get the expected result.

However, If I run the webservice FROM eclipse AND using the same tomcat instance, it is not able to find a resource file (the XSD file I used to check the XML structure of a file).

The code to get the URL of this XSD is the following one:

url = Application.class.getResource(sFile); if(url != null) { return url; } url = FileUtil.class.getResource(sFile); if(url != null) { return url; } url = FileUtil.class.getClassLoader().getResource(sFile); if(url != null) { return url; } url = ClassLoader.getSystemResource(sFile); if(url != null) { return url; }

When I deploy the war file directly from tomcat, the "sFile" is located into the WAR under the WEB-INF/classes directory.

What can I do to put it working fine under Eclipse/Tomcat?

Thanks

Regards

Hello

I wrote a simple JaxWS webservice.

@WebService public class WSReport { @WebMethod(operationName = "buildReport") public boolean buildReport(@WebParam(name = "xml") final String xml) { return true; } }

I created the sun-jaxws.xml:

<?xml version="1.0" encoding="UTF-8"?> <endpoints xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime" version="2.0"> <endpoint name="Generate" implementation="com.tst.WSReport" url-pattern="/report"/> </endpoints>

And my web.xml file is:

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/j2ee/dtds/web-app_2_3.dtd"> <web-app> <listener> <listener-class> com.sun.xml.ws.transport.http.servlet.WSServletContextListener </listener-class> </listener> <servlet> <servlet-name>report</servlet-name> <servlet-class> com.sun.xml.ws.transport.http.servlet.WSServlet </servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>report</servlet-name> <url-pattern>/report</url-pattern> </servlet-mapping> <session-config> <session-timeout>120</session-timeout> </session-config> </web-app>


I have also put all the jar files of JAX WS RI on the lib folders of the web service.

I've build the war and it has the expected structure:

META-INF/
WEB-INF/
WEB-INF/classes/...
WEB-INF/sun-jaxws.xml
WEB-INF/web.xml

Now, I've put the war file on the webapps tomcat folder. Finally, I started tomcat. No errors happened.

However, when I try to access the application using the URL : http://localhost:8080/Generate/report, I get the following error on the browser:

HTTP Status 404 - /HelloWorld/hello
type Status report
message /Generate/report
description The requested resource (/Generate/report) is not available.

Anyone knows the cause of the problem?


Thank you

Hello,

I have built a JAXWS web service which returns an Object (ResultReport) as result. This class contains a result string and a SOAPMessage.

My webservices executes a method which builds a SOAPMessage. In the web service I have build a test class to verify if everything is OK.

My test class:

... final String sXml = getXml(); final ResultReport m = r.buildReport(sXml); final SOAPMessage msg = (SOAPMessage) m.getSoapMsg(); msg.writeTo(System.out);

My buildReport method:
public ResultReport buildReport(@WebParam(name = "xml") final String xml) { final ResultReport r = new ResultReport(); r.setFlag("OK"); // Checks if the received XML is not empty if(xml.isEmpty()) { r.setFlag("NOT_OK"); } final SOAPMessage m = (SOAPMessage) TestExport.process(xml); r.setSoapMsg(m); return r; }

The result is the expected. The value of the SOAPMessage is written on the console and it is:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Header/><SOAP-ENV:Body><Result>OK</Result><Message/></SOAP-ENV:Body></SOAP-ENV:Envelope>

However, when I call the buildReport webservice method from a client class, I get an error:

Exception in thread "main" com.sun.xml.internal.ws.protocol.soap.MessageCreationException: Couldn't create SOAP message due to exception: XML reader error: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,95] Message: XML document structures must start and end within the same entity. at com.sun.xml.internal.ws.encoding.SOAPBindingCodec.decode(Unknown Source) at com.sun.xml.internal.ws.transport.http.client.HttpTransportPipe.createResponsePacket(Unknown Source) at com.sun.xml.internal.ws.transport.http.client.HttpTransportPipe.process(Unknown Source) at com.sun.xml.internal.ws.transport.http.client.HttpTransportPipe.processRequest(Unknown Source) at com.sun.xml.internal.ws.transport.DeferredTransportPipe.processRequest(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber.__doRun(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber._doRun(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber.doRun(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber.runSync(Unknown Source) at com.sun.xml.internal.ws.client.Stub.process(Unknown Source) at com.sun.xml.internal.ws.client.sei.SEIStub.doProcess(Unknown Source) at com.sun.xml.internal.ws.client.sei.SyncMethodHandler.invoke(Unknown Source) at com.sun.xml.internal.ws.client.sei.SyncMethodHandler.invoke(Unknown Source) at com.sun.xml.internal.ws.client.sei.SEIStub.invoke(Unknown Source) at $Proxy30.buildReport(Unknown Source) Caused by: com.sun.xml.internal.ws.streaming.XMLStreamReaderException: XML reader error: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,95] Message: XML document structures must start and end within the same entity. at com.sun.xml.internal.ws.streaming.XMLStreamReaderUtil.wrapException(Unknown Source) at com.sun.xml.internal.ws.streaming.XMLStreamReaderUtil.next(Unknown Source) at com.sun.xml.internal.ws.streaming.XMLStreamReaderUtil.nextContent(Unknown Source) at com.sun.xml.internal.ws.streaming.XMLStreamReaderUtil.nextElementContent(Unknown Source) at com.sun.xml.internal.ws.encoding.StreamSOAPCodec.decode(Unknown Source) at com.sun.xml.internal.ws.encoding.StreamSOAPCodec.decode(Unknown Source) at com.sun.xml.internal.ws.encoding.StreamSOAPCodec.decode(Unknown Source) ... 16 more Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,95] Message: XML document structures must start and end within the same entity. at com.sun.org.apache.xerces.internal.impl.XMLStreamReaderImpl.next(Unknown Source) at com.sun.xml.internal.ws.util.xml.XMLStreamReaderFilter.next(Unknown Source) ... 22 more

The error happens in the buildReport method when I try to build my SOAPMessage (final SOAPMessage m = (SOAPMessage) TestExport.process(xml);).

For now, it is a simple SOAPMessage. But I am doing this because I want to add an attachment into the SOAPMessage and return it to the client who called the web service.

Thanks for any help

Hello,

I have a class with an object which contains a list of Strings. In this class I have a runnable method where I want to access this object to add an element in his list.
However, it seems that in my runnable method, the object is not modified. No error is happening.

MyObject o... SwingUtilities.invokeLater(new Runnable() { @Override public void run() { try { ... o.getList().add("aa"); } } } int size = o.getList().size(); => size = 0

What can I do to solve my problem?

Thanks

Hello

I have build a Java (swing) application. With my ant file I have now a directory with the exe file of my application, the jar file of my application classes and some subdirectories with configuration files.

With this kind of structure everything works fine on my pc.

Now, I would like to find a clean and professional solution to distribute/install this application on several pcs without having to go install on each pc one by one. I would like to have something automatic which would install my package in several pcs of my choice.

Do you have any suggestion to do this kind of stuff?

Thanks

Hello,

I have a question which could have been put in other section of the forum because it is related with several areas of the Java world.

Imagine that I want to develop a web application on Java. This application will have several interfaces with objects (forms), which will interact with a database, and must be able to show tables with information, provide normal insert/update/delete actions, show charts, etc. I want the interfaces be nice looking and the application must be light and effective.

My question is simple. The answer I don't think its so simple.

Today, we have several Java technologies. Everyone have their pros and cons: JSP, Java RCP, JavaFX, etc.

Which solution would you suggest for building such application? Last time I developped a web application it was 5 years ago. I used JSP but now, I have the feeling that this technology is old and others are/can be better...

Thanks

Hello,

Thanks for your answer. After trying and trying, I figure that the object returned was an array of objects.
So depending on the scenario, I test if the returned object is an instance of array or something else and then I execute the proper action.

Best regards.

Hello,

In my rails application, I am using couchrest_model to connect to a couchDB database.

I have a model like this:

class Author < CouchRest::Model::Base property :id, Integer property :title, String property :first_name, String property :last_name, String # view to get only the documents which starts with "authors" - Table Authors view_by :id, :map => "function(doc) { if(doc._id.indexOf('authors') == 0) { emit(null, doc); } }" end

In the controller the function is simple:

def list @authors = Author.by_id() end


And in the view I iterate the @authors to show the results.


I would like to implement pagination but I don't know how. I already implemented pagination before, when I was using a PostgreSQL database and active records (will_paginate), but now, I am stuck with this.

Anyone can help me with a simple example?

Hello

In my RoR application, I am using Couchrest_model to access a CouchDB database.

I have a model which represents an scientific Article.
I am going to simplify my model to explain it better. An article can have a title, a year and one or more authors.

In the couchDB database, an article can be represented like this:

article { title = "abc", year = "2012", author = { name = Paulo, age = 34 } }

(In the case the article only have an author)

OR

article { title = "abc", year = "2012", author = { [0] { name = "Paulo", age = "34" } [1] { name = "Philippe", age = "32" } } }

class Article < CouchRest::Model::Base property :title property :year property :author end

In the case my article have only one author, I can access author's information (name and age) like this:
Article.author.name
Article.author.age

But, how can I access the information of authors if the article have more than 1 author?

Hello,

I am writing a RoR application that connects to a couchDB database using couchrest_model.

The definition of my model is the following one:

class BdsDataAuthor < CouchRest::Model::Base
property :id, Integer
property :first_name, String
property :last_name, String
end

I would like to be able to get the list of the model columns, e.g., the result of
BdsDataAuthor.columns would be [id, first_name, last_name]

Is it possible? I saw that active_record provides this kind of method (column_names), but since I am not using active_record...

A solution that I tried is to create a method in the model class (it works but its not the "best" solution...):

def getColumns
columns = Array.new
columns << "id"
columns << "first_name"
columns << "last_name"
end

Any idea/suggestion to solve this problem?

Thank you

Yes, this was the problem...

Thank you very much.

Best regards.

Hello

I am writing a RoR application which connects to a noSQL database
(couchDB).


In the database, I have an author document. The author has a first_name
and a last_name. It also have inside another document: a book. The book
has a title and a year of publication.

Example:
{ author { "first_name" : "abc", "last_name" : "def" "book" { "title" : "the jungle book", "year" : "1922" } } }

I am trying to define the Author model file so I can access Author's
information as so related book information:

class Author < CouchRest::Model::Base property :first_name property :last_name property :book ... end

However, when in the HTML file I try to access to the book author's
information, I get errors.

HTML example:

<td><%=h author.first_name %> <%=h author.last_name %> <%=h author.book.title %></td>

The error I get is:
undefined method `title' for :book:Symbol


It's the first time I am developing a RoR application using a CouchDB
application, so I am pretty sure that the problem comes from the way I
am defining the Author's model file.

Can anyone help me about that?

Thank you

Hello

I am developing an application on rails using a couchDB database. I already can connect to the database and view some information.
Now I am trying to create a new object of my model.

My model is named author. My controller is named authors.

The code of my model is the following one:

class Author < CouchRest::Model::Base timestamps! property :_id, String property :id, Integer property :title, String property :first_name, String property :last_name, String view_by :id, :map => "function(doc) { if(doc._id.indexOf('Authors_') == 0) { emit(null, doc); } }" end

The code of my controller is the following one:

class AuthorsController < ApplicationController def list @authors = Author.by_id() end def new @author =Author.new respond_to do |format| format.html # new.html.erb format.xml { render :xml => @author } end end end

The code of my new.html.erb file is the following one:

<h1>New author form</h1> <% form_for @author do |f| %> <div class="field"> <p><%= f.label :title %> <%= f.text_field :title %></p> </div> <p><%= f.label :first_name %> <%= f.text_field :first_name %></p> <p><%= f.label :last_name %> <%= f.text_field :last_name %></p> <div class="action"> <p><%= f.submit :create %></p> </div> <% end %> <%= link_to 'Back', authors_path %>

The list method is working fine, it shows what I am expecting to.
However, the "new" html page does not shows anything except the title and the "back" link. No error is generated. Everything is ok except that the form is not generated/displayed/rendered.
Does anyone have an idea about the problem/solution of it?
Thank you
Best regards
