Accessing file shares from JSP

Hi,
I need to be able to access file shares from a JSP page. Here's the JSP code:
<%@ page language="java" %>
<%@ page import="java.io.*" %>
<%@ page errorPage="errorPage.jsp" %>
<%
String fileSystemPath = "\\\\130.26.1.199\\MeetingManager30\\test.txt";
File f = new File(fileSystemPath);
f.createNewFile();
%>The above code resides in a server with IP 130.9.68.6 and is deployed onto the Tomcat on the server.
When I tried to run the above code, I got this error
java.io.IOException: Access is denied at java.io.WinNTFileSystem.createFileExclusively(Native Method) at java.io.File.createNewFile(File.java:827) at org.apache.jsp.test_jsp._jspService

I know it's a security issue, because I've encountered the equivalent problem in ASP/IIS, and I had to give a domain user rights to both the IIS Virtual Directory, and the file share to be able to access.
Any ideas how to set up Tomcat to be able to access the file share successfully?
Thanks in advance!

Hello Veer,
From what you have posted it looks like while logging your error another problem occurred. Did you get any output from your System.out calls? If not can you try adding a few in order to home in the problem area.

Urgent-how to access custom tag from jsp tag

I have a problem accessing a custom tag from a jsp expression.
Details: I have a custom tag that returns a string variable. I need to access that variable from jsp expression <%%>.
Can any body help me?

Tags don't "return" values as in the normal sense.
They can only support TEI (Tag Extra Information) that just stuffs a declared variable into the page's state.
For example, if the tag class had a public method called getValue(), you could do the following:
<xmp:mytag id="foo"/>
<%
out.println("value is " + foo.getValue());
%>

Issues accessing domain share from domain controller

Hi,
About 2 weeks ago, 2 of my domain controllers at one of our facilities has lost access to a domain share. If I try to access the share from the dc's, it prompts for a username/password. Now if I go to my workstation at corp, the share works fine. I can't
seem to figure out where the problem is. Any suggestions?
Thanks in advance!

You can use dcdiag and repadmin to check your DCs and your replication health status. That should let you see if something is wrong.

How to access ZFS share from Windows 7?

I am new to UNIX and am having a hard time to get a ZFS share to access from windows 7 on my home network.
I was able to access both WHS 2011 and QNAP 459 share on SE 11 by using the file manager - Server - windows & then just using the IP address, username, password. That was easy or at least similar to what I was used with windows 7.
However, I have yet to be able to access a ZFS pool containing a share that I can access from another windows 7 machine at home.
Apparently, I can mount the share from windows but the login name/password do not get accepted when I add a network connection in windows. Windows does seem to find the path \\solaris\tank_share1 and even mounts it, but the login for SE 11 does not work for some reason.
I changes the workgroup name to WORKGROUP in windows but that did not change anything. I tried to edit the pam.conf file by changing the ownership from root to myself so I could use gedit since it has been 15 years since I last used vi. However, that corrupted the setup as I got "system error" message on reboot that never got out of that infinite loop.
I am basically using the instruction through the following link:
http://blogs.oracle.com/observatory/entry/accessing_opensolaris_shares_from_windows
Any help to get this problem resolved is much appreciated
Thanks,
Kurt

The documented procedure of having to edit the pam_conf file seems to work followed by resetting one's password seems to work after all. I believe, by taking away ownership from root to "admin user" screwed things up. I had to relearn how to use vi but that didn't take very long.
Got about 50 MB/s speed coping from Windows SSD to SE11 SSD via very small (5 GB) RAIDZ array in VMWare (running on top of WIN 7-64). I have to try native SE11 SSD next as the VMWare setup is just for practice.
Q: Is there a way to launch gedit from the terminal window in root mode so I wouldn't have to use vi?

I want to screen/file share from my Macbook Pro to IMac. I can't see it when I open the Shared folder.

From my macbook..I have a few times seen the IMac listed on the devices list. I don't know what I did to make it appear but I was able to
file share..etc. Now ...when I open Sharing folder from laptop..I see "IMac" as Computer name. Should this be changed? Screen Sharing:On..Allow access for all users is checked. I don't know how to launch my Imac screen again. Please advise. Thanks!

If screen share it turned on with both computers there are several ways to then screen share. First ensure Screen Sharing is selected on each computer in System Preferences - Sharing. Once this is done then open a Finder Window on the Left you will see Shared on the left side, then click the computer you want to share and you will see a screen like the following. From there click where it says Screen Share.

Setup mySQL and access the same from jsp

Hi,
I have installed the MySQL in local desktop in d: drive. As per the documentation, have created my.cnf file to point sql directory in d drive.
Now I dont know how to proceed further. I need to see if MySQL installation is fine, create table and access the data in jsp page. Please advice.
Thanks in advance.

For MySQL help try a MySQL forum.
For connecting to the database, use JDBC. You can get the MySQL JDBC driver from www.mysql.com.
From there just follow standard java database connection setup.

Cant Access external shares from my admin account

Hi,
the title says it all.
No matter if I try to connect via smb or afp. If I try to log in from the admin account to external afp or smb shares the login is refused cause of permissions.
IF I do switch to a user other than the system admin account, the access to external shares works like a charm.
In my case its an external NAS from Buffalo (Linkstation Duo).
Also from other Lion machines ... no problem when trying to access that share.
Im aware of the DHCAST128 changes but as you can read above it seems that this is not the issue.
Any hints or suggentions?
Thanks!
Andrew

Hi-
You can use the account that you use daily, as SuperDuper will clone the entire drive, which includes all accounts, applications and data. SD will require an administrator password to run the cloning, but this can be done from any account.

Random error accessing CIFS shares from Windows

I am setting up some CIFS shares to be used from Windows clients and in the process I had some random problems accessing the shares.
In hope of finding the answer I checked the CIFS Service and the Active Directory Service, and while watching the screen for Active Directory Service I saw that the "Selected Domain Controller" changed from one to another. I now stayed within this screen and noticed that the "Selected Domain Controller" continued to change and then I found the problem, because an unknown Domain Controller appeared. The IP was 216.150.17.8
I found that when ever this Domain Controller was the selected one, all access to CIFS shares from Windows clients failed! This is correct, because the 216.150.17.8 of course is unaware of all users in Our Domain
So the Questions are:
- what is happening?
- and how to solve this?
- why is a Domain Controller 216.150.17.8 sometimes the Selected Controller?
- where does this 216.150.17.8 come from?
Have You seen anything like this?

I now have found out why the DC changes - it is because the CIFS service is restarting ;-(
This is a log snip

Any ideas?

Problem with access to SipFactory from jsp-pages in JBoss environment

Hello!
I have an installation of the OCMS 10.1.3.3. deployed into a JBoss (jboss-4.0.5.GA) environment. Unfortunately I have a problem with accessing the SipFactory from a jps-page. Encouraged by the "messagesender" example I tried to get an instance of SipFactory from my jsp-page simply by calling:
SipFactory sipFactory = (SipFactory) application.getAttribute(SipServlet.SIP_FACTORY);
But unfortunately there seems to be no attribute "SipServlet.SIP_FACTORY" and I only get a null pointer. I have also tried running that code in the orignal messagesender example but it didn't work either. So I wonder if this should definetely work in a JBoss environment or if this might be a known problem. Is there anything that I could check/do regarding this problem? I suppose there must be an oracle module which should take care of making the SipFactory availabe after it is deployed. Perhaps something went wrong during the deployment?!
Best regards,
Tim

Hi
On JBoss, OCMS does not support converge applications.
I.e the SipFactory can be retrieved from the servlet context when running on OC4J.
Instead the SipFactory can be found in JNDI as described in the Developer's Guide:
"External Access to SIP Servlets
To enable convergent applications between SIP and HTTP, the OCMS Container allows you to get access to the javax.servlet.sip.SipFactory by looking it up through JNDI. The SIP Factory will be registered under the same name as the display name of your SIP servlet as illustrated in Example 2–12. The <display-name> in the sip.xml in this case must be "My sip app".
Example 2–12 Accessing the Data for a SIP Session through JNDI
InitialContext ic = new InitialContext();
SipFactory sipFactory = (SipFactory)ic.lookup("sip/My sip app");"

Accessing File Shares Over NAT

Hello,
I am working with a client that set up a new sub net that uses hide NAT. When I try to access a file share on a server in a different sub net, I can only browse for a few seconds and then an error such as "Server service not started" or "network
name no longer available" appears, and I can't browse folders on that server anymore (it has Server 2003 SP2). Netmon found that the connection was constantly being reset. If I reconfigure the same client (XP SP3) with it's original unNATed IP address,
everything works fine, and the Windows firewall is disabled on both the server and client. Is there a trick to get CIFS or SMB or whatever to work over hide NAT?
Thanks!

Hi,
SMB uses a single session for a pair of IPs and all file transfer between these 2 IPs are made over this session. This makes the file transfer more efficient over the network. On the flip side, since only one SMB session is maintained, clients coming through
NAT will have problems since all these clients are presented as a single IP to the server. With SMB, only a single session will be maintained and thus there is nothing unique for each client. This breaks the communication.
We will need to use NetBIOS over TCPIP in place of SMB. This can be achieved by:
1. Disabling SMB on the server or on all the client machines by setting the registry:
Name: SMBDeviceEnabled
Type: REG_DWORD
Value: 0
The location of the registry key is:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBT\Parameters. You may have to create this if not already existing.
2. Block TCP port 445 for the segment accessing shares through NAT
