Thank you for your answer I manage to make it work.

Hi,

I have a seam generated application with Statles sessions beans.
The app name is myapp and inside it there is a myapp.jar file wich contains the stateless sessions.

After jboss 4.2.3 is started I can see my statless session beans mapped to myapp/EJBNAME/local
EJBNAME = name of the Statles EJB class

I am able to lookup any statless session bean using the jndi mapping above as long as myapp.jarfile name is unchanged.

If I change myapp.jar file name to test.jar and also change the in application.xml this :
<module>
<ejb>myapp.jar</ejb>
</module>
to:
<module>
<ejb>test.jar</ejb>
</module>

I am unable to lookupany of my statless session beans.

I do not know why is this and if there is a work around.

Could anyone help on this?

Thank you

That was it.

Sometimes is right infront of you and you just can't see it.

Thank you Ulf.

It apears that the first byte that was read from the file is sent over and over to the server.

Couldn't found out more.

Hi!

I want to upload pictures on a server using HttpURLConnection.

My servlet is deployed in Tomcat 5.5.17.

The problem is that the upload never stops and the wrong data is uploaded.

On the server the uploaded value is allways 255 for each byte.

I belive that the communication is binary.

Did anyone encounterd this problem?
Any help will be appreciated.

Thank you.

Thank you Dave!
That solved it.

You are right about the shouting.

Thanks again.

Hi!

I have a jar in which is my application and a jar with dom4j;

I try to start my application as bellow:

java -classpath ./lib/dom4j-1.6.1.jar -jar httpclient.jar checkupdate

I get this exception:
Exception in thread "main" java.lang.NoClassDefFoundError: org/dom4j/Branch
at com.httpclient.main.MainHttpClient.checkForUpdates MainHttpClient.java:87)
at com.httpclient.main.MainHttpClient.main(MainHttpClient.java:26)

If I use this line it works

java -classpath ./lib/dom4j-1.6.1.jar;httpclient.jar com.httpclient.main.MainHttpClient checkupdate

In the Manifest of the jar file the main class is correctly specified.
I looked inside dom4j-1.6.1.jar and the reported missing class is there.

I want to use relative paths.

Have anyone encountered this problem?

Thanks

Hi!
Thanks for pointing out that the fields might be in a super class.
They were!

Also I would like to add that the fileds were package accessible (no access modifier: private, public or protected infront of them). So to be able to get them I set the accessible flag of each field to true:

addressField.setAccessible(true);
portField.setAccessible(true);

Only afthere setting true on accessible flag I was able to get the values
Thanks all for repllying so quick.

Hi!

I have this code:

Class cls = stream.getClass();
Field addressField = cls.getDeclaredField("address");
Field portField = cls.getDeclaredField("port");
this.dataAddress = (InetAddress)addressField.get((RecvSSRCInfo)stream);
this.dataPort = portField.getInt((RecvSSRCInfo)stream);

stream is of type com.sun.media.rtp.RecvSSRCInfo

In Eclipse on Expressions window(watch) I see the fileds address and port of stream object, they have the expected values also but when I try to get these values using reflection it throws NoSuchFieldException.

Can anyone please help with this?

Thank you!

Hi all!

In a JSF form i have this code fragment.

<f:verbatim >
<input name="importFile" type="file" size="10">

Hi, I want to write a jdbc driver for an access database and I could use some help (source code or links maybe a tutorial on how to do it).Don't want to use odbc just jdbc to connect to the database.One more question : is it possible to connect to a database just specifing the path and the name of the database ?
Tanks.

Hi Marilyn de Queiroz.
Your solution did not worked for me.
I tried an other approach and it worked.
In web.xml file I put a the folloing code:
<servlet-mapping>
<servlet-name>Register</servlet-name>
<url-pattern>/Register</url-pattern>
</servlet-mapping>
and only after that it worked.

Hi .
You get this error if the class is not in your import section or if the jar file that contains it is not in your classpath.Try to put the jar file in your JAVA_HOME/lib and in JAVA_HOME/jre/lib/ext and in your CATALINA_HOME/lib

Hi!
Can anyone help me ?
I have a servlet in the WEB-INF\classes
and when I try to access the servlet
I get the following error:
HTTP 404 - File not found
Internet Explorer
This is the web.xml content:
<web-app>
<display-name>Proiect SICE</display-name>
<description>Proiect pentru scoala.</description>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

<servlet>
<servlet-name>Register</servlet-name>
<servlet-class>Register</servlet-class>
</servlet>
</web-app>
This is the content of the servlet:
public class Register extends HttpServlet
{
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<HTML><HEAD><TITLE>Server respons</TITLE></HEAD>");
out.println("<BODY><B>bla bla bla ...</B>");
out.println("</BODY></HTML>");
out.close();
}
}
Should I write anything else in the web.xml ?
Why can't orion see my servlet ?
