Hi,

I have a web application deployed in Jboss. Accessing http://localhost:8080 && http://<system IP in LAN >:8080 works fine. But when i use the ip provide by By ISP
http://< IP from ISP >:8080 it doesnt work. I have done port forwarding in the router configuration to 8080 for the System IP. Tested port forwarding & its OK.
How can i access the web application from outside network [internet].

Thanks & Regards,

hi,

I would like to keep my user session valid for the day, so that I do not get a session time out. But in standardjboss.xml, I have defined a max-bean-life, the time for which the session bean is valid. In this context, can anyone please let me know how can I set the max-bean-life. Can i set this to be the same as the session time out figure ? Is there any performance issues.

Regards,

I am using getColumns method of databasemetadata which returns resultset.
This resultset returns information about each columns as seperate rows.I want to iterate through these rows.
please note that I am not using any preparedStatement or createstatement methods.
Please tell me how to make this resultset scrollable.
Thanks in advance.
I tried to read a blob value from a Mysql database.But this field is obtained as java.sql.types varlongbinary instead of BLOB.
Now when i tried to read the content of the blob field which is an xml using
getbinaryStream method, i encountered some problems.
I have read the contents into a byte array using read method of inputstream
and when i converted this byte array to a string using toString it returns the byte array object value and not the orirginal contents.
Actually i want to read this content and insert into a clob field of an oracle database.
Somebody Please help me to sort out the problem.
Hi ,

I have an IDEFIX Application(J2ee) whose Client is built on Java Swing.
Addtionally this application had to invoke an 3rd party Software.
On invoking the 3rd party Software from this application & on load
of the 3rd party Software.The Swing Behavior of the client
of IDEFIX Application behaves in a different way . for Eg : the
Disabled buttons are not visible ,enterlly the view becomes somewhat
differrnt & distorted.
IDEFIX Application invokes the 3rd party s\w through a Thread.

But The main problem is that it works properly in Linux ,
The problem arises in Windows system.

Please help in this regard,
