Problem in accessing NFS using WebNFS.

Hi,
We are trying to access an NFS area from our web application which is deployed in Weblogic server by the use of WebNFS api.
Both our weblogic server and NFS area present in a Solaris box(5.8 release).
For NFS configuration the entries made to the config files as
/etc/dfs/sharetab
/ics_data - nfs root=anon
/etc/dfs/dfstab
share -F nfs -o root=anon /ics_data
For reference, the following commands do list the exported file system as
> df -k | grep ics
/dev/dsk/c1t13d0s6 1026367 12 964773 1% /ics_data
> /usr/sbin/showmount -e
export list for sunbom4:
/ics_data (everyone)
Also the nfs daemons are running
> ps -ef | grep nfs
root 9599 1 0 16:05:58 ? 0:00 /usr/lib/nfs/mountd
root 9601 1 0 16:05:58 ? 0:00 /usr/lib/nfs/nfsd -a 16
root 25505 1 0 15:14:25 ? 0:00 /usr/lib/nfs/lockd
daemon 25506 1 0 15:14:25 ? 0:00 /usr/lib/nfs/statd
Our java code as follows
XFile xfd = new XFile("nfs://[IPAddress]:2049//ics_data");
System.out.println("xfd.exists() = " + xfd.exists());
XFile xfd1 = new XFile("nfs://[IPAddress]:2049//ics_data/testFile.txt");
System.out.println("xfd1.exists() = " + xfd1.exists());The output is
xfd.exists() = false
xfd1.exists() = false
We have confirmed the nfs port by
cat /etc/services | grep nfsnfsd 2049/udp nfs # NFS server daemon (clts)
nfsd 2049/tcp nfs # NFS server daemon (cots)
Though the file actually exists on the specified location, we could not able to get it by using XFile and NFS url. Kindly advice if we are missing out something some where or incase we are taking any wrong approach.

We have also tried to associate the 'public' file handle with the shared file system by changing the entry in /etc/dfs/dfstab file as
share -F nfs -o root=anon,public,log /ics_data
And our java code as
XFile xfd = new XFile("nfs://[IPAddress]:2049");
System.out.println("xfd.exists() = " + xfd.exists());
XFile xfd1 = new XFile("nfs://[IPAddress]:2049//testFile.txt");
System.out.println("xfd1.exists() = " + xfd1.exists());But the same problem still persists.
Can any one please help us out to identify the problem?

hi
to use java bean u MUST follow the two conviosions:
1. the class u want to make a bean from it must have no-argument constructor
2. u must provide setter and getter for every instance variable , the name of instance varible must begin with small letter and its setter and getter must be like setXxx() and getXxx()
the correct bean is :
package valueobjects;
     public class login1{
     String name;
     String password;
     public String getName()
               return name;
     public void setName(String name)
               this.name = name;
     public String getPassword()
                return password;
     public void setPassword(String password)
                this.password = password;

Try resetting the SMC Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support
and PRAM How to Reset NVRAM on your Mac - Apple Support
If those don't help you can try a cleaning disc or a quick shot of compressed air. Chances are that your drive has failed, join the club it's not all that uncommon. You can either have it replaced or purchase an inexpensive external drive. Don't buy the cute little Apple USB Superdrive, it won't work on macs with internal drives working or not.

Problems Setting up NFS

Hi.
I've been having problems setting up NFS on a LAN at home. I've read through all the Arch NFS-related threads and looked at (and tried some of) the suggestions, but without success.
What I'm trying to do is set up an NFS share on a wireless laptop to copy one user's files from the laptop to a wired workstation. The laptop is running Libranet 2.8.1. The workstation is running Arch Linux with the most up-to-date (as of today) software, including NFS.
I have the portmap, nfslock, and nfsd daemons running via rc.conf, set to run in that order.
I've re-installed nfs-utils and set up hosts.deny as follows:
# /etc/hosts.deny
ALL: ALL
# End of file
and hosts.allow as follows:
# /etc/hosts.allow
ALL: 192.168.0.0/255.255.255.0
ALL: LOCAL
# End of file
In other words, I want to allow access on the machine to anything running locally or on the LAN.
I have the shared directories successfully exported from the laptop (192.168.0.3), but I have not been able to mount the exported directories on the workstation (192.168.0.2).
The mount command I'm using at the workstation:
mount -t nfs -o rsize=8192,wsize=8192 192.168.0.3:/exports /exports
There is an /exports directory on both machines at root with root permissions. There is an /etc/exports file on the NFS server machine that gives asynchronous read/write permissions to 192.168.0.2 for the /exports directory.
I receive the following message:
mount: RPC: Program not registered
This appears to be a hosts.allow/hosts.deny type problem, but I can't figure out what I need to do to make RPC work properly.
Some additional information, just in case it's helpful:
This is the result if running rpcinfo:
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper

Thanks for any help here!

Hi ravster.
Thanks for the suggestions. I had read the Arch NFS HowTo and did as you suggested get rcpinfo for the server machine. The Libranet NFS server is configured rather different since the NFS daemons are built into the default kernel.
Since I needed to complete the transfer immediately, I gave up for now trying to set up NFS and used netcat (!) instead to transfer the files from the Libranet laptop to the Arch workstation. The laptop will be converted to Arch Linux soon so I think I'll be able to clear things up soon. I haven't had any problems setting up NFS with homogeneous (i.e., all Arch or all Libranet) computer combinations.
Thanks again.

Accessing NFS mounts in Finder

I currently have trouble accessing NFS mounts with finder. The mount is O.K. I can access the directories on the NFS server in Terminal. However, in Finder when I click on the mount, instead of seeing the contents of the NFS mount I only see the "Alias" icon. Logs show nothing.
I am not sure when it worked the last time. It could well be that the problem only started after one of the lastest snow leopard updates. I know it worked when I upgraded to Snow Leopard.
Any ideas?

Hello gvde,
Two weeks ago I bought a NAS device that touted NFS as one of the features. As I am a fan of Unix boxes I chose an NAS that would support that protocol. I was disappointed to find out that my Macbook would not connect to it. As mentioned in previous posts (by others) on this forum, I could see my NFS share via the command line, but not when using Finder. I was getting pretty upset and racking my brain trying to figure it out. I called the NAS manufacturer which was no help. I used a Ubuntu LiveCD (which connected fine). I was about ready to give up. Then, in another forum someone had mentioned the NFS manager App.
After I installed the app and attempted to configure my NFS shares, the app stated something along the lines of (paraphrasing) "default permissions were incorrect". It then asked me if I would authenticate to have the NFS manager fix the problem. I was at my wits end so I thought why not. Long story short, this app saved me! My shares survive a reboot, Finder is quick and snappy with displaying the network shares, and all is right with the world. Maybe in 10.6.3 Apple will have fixed the default permissions issue. Try the app. It's donationware. I hope this post helps someone else.

Accessing NFS from Java

I have requirement to create and write files on a NFS file storage. I need to do this from a Java application running on Windows 2008 Server.
How do i implement this requirement?. Is there any Java Library to achieve this?.
I have read documentation on WebNFS (Java Extended File System API). Where can i download this library?.
WebNFS is renamed to YaNFS and made as open source (http://java.net/projects/yanfs). But YaNFS project doesn't appear to be active anymore.
Thanks.

809385 wrote:
I have requirement to create and write files on a NFS file storageSo how would you do this outside of Java? Presumably you would mount the NFS on some Windows 2008 mount point (a quick Google search says this is not difficult). Why can't you do the same from Java (Process builder springs to mind) and then access the NFS using standard Java IO.

UMASK & DIR_MODE for local & NFS use?

I am trying to replicate my Debian setup on Arch, where I have UMASK set to 002 in /etc/login.defs and DIR_MODE to 0700 in /etc/adduser.conf, so that all files created on my NFS share have mask 0664 and local users' home dirs are created with mask 0700.
On Arch there is no /etc/adduser.conf, and adduser just creates users' home dirs according to UMASK set to 077 by default in /etc/login.defs, which means there is no "easy" way to differentiate, and to get the mentioned behavior, the only way seems to be to either patch /usr/sbin/adduser with setting the mode to 0700 after homedir-creation, or to do that manually after adding a new user.
Setting UMASK always has been a problem, because afaik there is no way to separate on local and NFS use, so to have files on a NFS share be fully accessible by a group of users (and be readable by others), one has to set UMASK to something like 002 on all accessing machines, and then take care of local user protection (by setting mode to 0700 to users' homedirs).
Does anybody know if there is any easier way to accomplish that task?
Any hint for a different proceeding?

It's possible but with problems...
When JNLP is on sandbox mode no problem. When it's on J2ee-permissions or all-permissions mode you've got to configure the javaws.policy with permissions of sandbox. So the administrator just haven't to grant access to the policy file by customers...
When Java Web Start use JRE younger than 1.4 no problem, but when JRE is 1.4 or more, Java Web Start seems to don't use the javaws.policy file. I search informations about this problem for 2 weeks but I find nothing...

Java API, problem with secondary keys using multi key creator

Hi,
I'm developing an application that inserts a few 100k or so records into a Queue DB, then access them using one of four Hash SecondaryDatabases. Three of these secondary dbs use a SecondaryMultiKeyCreator to generate the keys, and one uses a SecondaryKeyCreator. As a test, I'm trying to iterate through each secondary key. When trying to iterate through the keys of any of the secondary databases that use a SecondaryMultiKeyCreator, I have problems. I'm attempting to iterate through the keys by:
1: creating a StoredMap of the SecondaryDatabase
2: getting a StoredKeySet from said map
3: getting a StoredIterator on said StoredKeySet
4: iterate
The first call to StoredIterator.next() fails at my key binding (TupleBinding) because it is only receiving 2 bytes of data for the key, when it should be getting more, so an Exception is thrown. I suspected a problem with my SecondaryMultiKeyCreator, so I added some debug code to check the size of the DatabaseEntries it creates immediately before adding them to the results key Set. It checks out right. I also checked my key binding like so:
1: use binding to convert the key object to a DatabaseEntry
2: use binding to convert the created DatabaseEntry back to a key object
3: check to see if the old object contains the same data as the new one
Everything checked out ok.
What it boils down to is this: my key creator is adding DatabaseEntries of the correct size to the results set, but when the keys are being read back later on, my key binding is only receiving 2 bytes of data. For the one SecondaryDatabase that doesn't use a SecondaryMultiKeyCreator, but just a SecondaryKeyCreator, there are no issues and I am able to iterate through its secondary keys as expected.
EDIT: New discovery: if I only add ONE DatabaseEntry to the results set in my SecondaryMultiKeyCreator, I am able to iterate through the keys as I would like to.
Any ideas or suggestions?
Thank you for your attention,
-Justin

Hi Justin,
Sorry about the delayed response here. I have created a patch that resolves the problem.
If you apply the patch to your 4.6.21 source tree, and then rebuild Berkeley DB, the improper behavior should be resolved.
Regards,
Alex

Exception access violation using jlong instead of jint

Hi,
I hope you can help me.
I'm using Java5 under Windows XP and I'm developing under Eclipse.
I try to use an "old" c-Application accesed via JNI.
Status Quo is that, I have access to the c-side, over my JNI-conform DLL. My current task is to translate the c-side structs to java-objects. This also works, but only with limitation.
Calling methods bidirectional is working, manipulation a java-object is like a walk on an warm and sunny Saturday afternoon.
But I'm not able to use all possible parameters (for now I have tried to use jobject, jstring, jint, jboolean, jlong).
The first problem I had, were using Strings as parameters, but this now I deal with the loopway over java/lang/object (using java/lang/String results in an access_violation).
The next problem, and the harder one, is, that I cannot use the type long or jlong.
int (jint) is no problem, with int all works fine, but if I change the environment, creating and using long, I allways get an the access_violation shown below.
Is there anything, I need to know?
working c-side-code:
jobject someObject;
jint anIntegerValue;
anIntegerValue =5;
jmethodID mid3 = (*env)->GetMethodID(env, cl, "initReturnSomeObject", "(ILjava/lang/Object;)Ljava/lang/Object;");
               if(mid3 == (jmethodID)0) printf("\ndooofes MethodName4!\n");
                         else {
                              const char* myParams;
                              myParams = "ooooohwow!!!";
                              someObject = (*env)->CallObjectMethod(env, jobj, mid3,
                                         anIntegerValue, (*env)->NewStringUTF(env, myParams));
                         }wokring java-side-code
public Object initReturnSomeObject(int i, Object obj) {
          String s = (String)obj;
          System.out.println("String: "+s+"\nInteger: "+i);
          some = new SomeObject(s,i);
          if(some==null) System.out.println("Some is not yet initialized, FEAR!!!!\n");
          else System.out.println("Yoh, I'm soooo many good!! \nSome:\nString: "+some.getS1()+"\nInt: "+some.getI1()+"\n");
          return (Object)some;
so, und this code, doesn't work. you can see, the changes are dramatically!! ;)
sorry for my sarcasm. I do not know, why it doesn't work.
jlong aLongValue;
aLongValue = 2;
jmethodID mid3 = (*env)->GetMethodID(env, cl, "initReturnSomeObject", "(JLjava/lang/Object;)Ljava/lang/Object;");

                         else {
                              const char* myParams;
                                 myParams = "ooooohwow!!!";
                              someObject = (*env)->CallObjectMethod(env, jobj, mid3,
                                        aLongValue, (*env)->NewStringUTF(env, myParams));
     public Object initReturnSomeObject(long i, Object obj) {
          String s = (String)obj;
          System.out.println("String: "+s+"\nInteger: "+i+"\nLong: ");
          some = new SomeObject(s,(int)i);
          if(some==null) System.out.println("Some is not yet initialized, FEAR!!!!\n");
          else System.out.println("Yoh, I'm soooo many good!! \nSome:\nString: "+some.getS1()+"\nInt: "+some.getI1()+"\n");

Hi,
I'm quite sure, the signature is correct. For failure check, yesterday I ran javap to check the signature, but I do also mean, that I changed the signature afterwards for several time. And, it works ;) at least the way, using Integer.
Trying to use java/lang/String everytime I got the Error, that the method could not be found - this is the part, I was wrong in my description. So the error-Message is a different one.
Belonging to the question for assumptions I made... it's difficult. I'm quite new to JNI, so, I don't know, what I can assume to do. The Method call seems to be a kind of reflection-mechanism. So I assume that the behaviour is similar. But reflection I'm not very firm, either ^^.
What I do assume is, that the parameter-value J fits to the java-type jlong. But a work around on this, I will try today. getting the jlong into an char* or using long instead of jlong or using Ljava/lang/Long; or a casted Long as Ljava/lang/Object; ...
I'm anxious to the ideas, I will have, bypassing this point. if there is no way, I will write a file, send a email or something like this ;)
Thx for thinking about my problem jschel!! It's great not to be alone.

My DVR security sofware that I access remotely uses a "dvr .ocx" file....when I try it in Firefox , either the latest non beta (3.6.1.5) or the new beta version (4.0 rc) it will NOT work as it says the plugin is missing... it works in IE 8,but not IE9...

My machine is Top of the range (my Company builds them so it had better be :) )
Amd 1100t , 8gb ram , Windows 7 64 bit etc, etc...
The is not a hardware problem , but a software problem with FF...Any help would be appreciated as I hate using IE 8 for anything at all :( but I have to keep it on my machines just to run my remote security cameras at my Computer shop ???
Original question...as question length is limited ...not very bright that limit by the way :(

As I own a Computer company I am fairly computer literate but cannot find a plugin that allows this to work in Firefox.... but I would have expected it to work in the new Firefox :(
All the best, Brett :)

The longer this thread continues, the more ancillary comments you throw in that aren't directly pertinent to your problem with your DVR software not working with Firefox 4.0. Sorry, I don't intend to continue with this discussion.
I do agree that ''something'' needs to be done better with regards to plugins for Firefox, but I do disagree with you as to whose responsibility that ''something'' is.

Problem when try to use ACSE+ Windows AD to authenticate two kind of WLAN c

I met a problem when try to use ACSE+ Windows AD to authenticate two kind of WLAN clients:
1. Background:
We have two WLAN: staff and student, both of them will use PEAP-MSCHAPv2, ACSE will be the Radius server, it will use Windows AD's user database. In AD, they create two groups: staff and student. The testing account for staff is staff1, the testing account for student is student1.
2. Problem:
If student1 try to associate to staff WLAN, since both staff and student WLAN using the same authentication method, the auth request will be send to AD user database, since student1 is a valid user account in AD, then it will pass the authentication, then it will join the staff WLAN. How to prevent this happen?
3. Potential solution and its limitation:
1) Use group mapping in ACSE(Dynamic VLAN Assignment with WLCs based on ACS to Active Directory Group Mapping), but ACS can only support group mapping for those groups that have no more than 500 users. But the student group will definitely exceed 500 users, how to solve it?
2) Use methods like âRestrict WLAN Access based on SSID with WLC and Cisco Secure ACSâ: Configure DNIS with ssid name in NAR of ACSE, but since DNIS/NAR is only configurable in ACSE, don't know if AD support it or not, is there any options in AD like DNIS/NAR in ACSE?
Thanks for any suggestions!

I think the documentation for ACS states:
ACS can only support group mapping for users who belong to 500 or fewer Windows groups
I read that as, If a user belongs to >500 Windows Group, ACS can't map it. The group can have over 500 users, its just those users can't belong to more than 500 groups.
