Java Doesn't Recognize Something That Exists?

I'm writing an XML checker for a homework assignment. I'm using a stack which uses a double linked list which uses nodes with a generic data type.
I ran into a problem after testing the program for the first time. I got a NullPointerException error at the instance where I tried to add a new node to the head. After a little digging I found out that apparently Java doesn't remember that I set the successor of "head" to be "tail". I've already spent 20 minutes going over the code that sets the tail as head's successor but I just can't see what I did wrong.
Exception in thread "main" java.lang.NullPointerException

     at Driver.main(Driver.java:16)The program is already too long to post here and broken up into multiple classes, so I will only post the important stuff. Note: Token is just a Record class that keeps two Strings, type and tagName for the xml tag to store.

A user on another forum h(http://preview.tinyurl.com/yjqx4a9) helped me find the problem. I had to create the head and tail first and then point them at each other. Thanks for all the help here.
@flounder Even though I've already solved my problem I am still confused by what you're saying. The double linked list I created has two placeholders so that I don't have to worry about how many nodes are included. To connect my new node I start at the head and point at whatever is connected to the head (whether it is the tail or another node) to set the successor and predecessor for the new node. I then break the old connections (from the head to the old node after it) and connect them to the new node. I don't see a problem in this, but I am most likely not understanding your concern.
I don't really want to let this go, because there might be a problem in my code that I don't see right now.
@AndrewThompson64 I'll use that the next time I have a problem. Thanks.

Since you explicitly defined your reference to be of type List<String> you can only call methods that List has. And elementAt(int) is a method that's not existing in the List interface.
Use .get(int) instead.

Forte doesn't recognize classes are compiled

In the Sun One Studio 4 Update 1 IDE, my Java source files are displayed in the Explorer window with the uncompiled badge icons next to them, even though the classes are already compiled. If I select a file to compile it, the IDE will compile it, and put the compiled class in the target directory correctly. But the uncompiled icon is still displayed. If I select the file again and compile, the IDE compiles it again, instead of giving me the message that the file is up to date.
Has anyone seen this problem?

Add the output dir to classpath.Did you ever use forte? It doesn't recognize classpath. It looks at the mounted directories and jars instead. And I do have the output dir mounted - otherwise, the compiler couldn't put the compiled classes in the right place.

Jar doesn't recognize another jar

Hi I packed my java class and additional files into a jar file, using the eclipse.
The class I packed uses another jar file. it works fine.
the problem is with my new jar that I created, since it doesn't recognize the other jar that the class uses and can't use it,
Although I included the other jar in my class path in the eclipse.
i don't know how to make that the new jar will know the other jar.
thanks.

Tecra M4 - DVD drive doesn't recognize any disk under Vista

Hi,
after the installation of Vista my dvd drive doesn't recognize any disks !
No upgrade from XP! It was a clean Vista installation.
I found several links about the registry entries upper and lower filter this entries doesn't exist in my registry under the class CDROM.
I tested the drive under XP it works fine and recognizes everything.
Drivers are correctly installed no problems in the device manager is prompted.
So i have no idea how to get it working, seems to be a Vista problem
Could any one help me ? I'm really frustrated about this
Thanks for your help

Maybe this helps:
- Remove the CD/DVD drive from the device manager.
- Then access the registry and remove the Upperfilters and Lowerfilters values completely from the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
- Then reboot the notebook
But what happens exactly? What disks are not recognized?

Java stored procedures and referencing classes

We are referencing to some classes/libraries which are not present in the database. In normal java world, you specify the libraries/classes needed to run your piece of code in the CLASSPATH and that forms part of your complete code.
Can java stored procedures in the database refer to libraries or class files it requires on the file system rather than the database? Is it possible to make this happen?
Thanks

pshiva,
Posting the same question to multiple forums usually doesn't increase your chances of getting an answer, and it just frustrates those wishing to answer you with the result being that any future questions you post may have less chance of being answered -- because of your uncourteous, initial behaviour.
I have answered your other thread:
java stored procedures and referencing classes
In my opinion, that forum (the Database JVM forum) is the most appropriate for your question.
Good Luck,
Avi.

Java doesn't pick up system's DNS settings change until restarted

Hello,
I have a service running on a few Linux computers. Those computers have a NIC, which is configured with a fixed IP address. So /etc/resolv.conf contains the IP address of the LAN's DNS server. But most of the time, the computers are not plugged into the LAN at all. Instead, they connect themselves periodically to the Internet by establishing a ppp connection. When it happens, the ISP's DHCP server assign them new IP parameters, including their DNS server's IP address. And /etc/resolv.conf gets updated with this address.
But it seems that java doesn't take care of DNS change taking place during a run. Which means that my program (started at boot with no connectivity at all) tries to connect to some host, and obviously trigger an "UnknownHostException" (at that point it does try to contact the LAN's DNS server). Quite logical. Later, the ppp link become active. But my program still try to contact the LAN's DNS server, despite the new configuration in /etc/resolv.conf. As such, it will forever trigger UnknowHostExceptions, until it gets restarted (it will then pick up the new settings) or it is plugged back into the LAN (it will finally reach the LAN's DNS server).
This is quite a problem as during one single execution, the machine may encounter several DNS configuration changes, and this problem basically means that it will be impossible for my application to resolve any name at all.
So is there a way to tell Java to re-read the system wide DNS configuration? Or is there some option to prevent Java to "cache" the DNS server to use?
To demonstrate my problem, I've written a simple test case, see below.
To get the problem:
1) Put a bogus DNS server into your /etc/resolv.conf
2) Start the test program. Wait for some time: it will trigger UnknownHostExceptions.
3) Fix the entry in /etc/resolv.conf, and check it actually works (eg ping www.google.be)
4) Test program will continue to trigger UnknownHostExceptions forever.
One interesting fact is that someone tried this test on Windows, and didn't suffer from this behaviour, eg the application reacts to DNS system settings changes dynamically. So it looks like a Linux-only problem.
Thanks in advance for your insight.

            try {
                resolved = InetAddress.getByName(urlString);
                System.out.println("Loop " + loopCounter + ": resolved IP address: " + resolved);
            } catch (UnknownHostException e) {
                System.out.println("Loop " + loopCounter + ": UnknownHostException");
                e.printStackTrace();
            loopCounter++;

                Thread.sleep(1000);
            } catch (InterruptedException e) {}
}

Well, the nameservice property allowing to specify my DNS server of choice is interesting (I didn't know about those), but not very usable, as the DNS server to use is not known in advance (it may be whatever the ISP tells me to use at the time where the ppp link gets established). So no real solution there.
The fact that it caches /etc/resolv.conf content for 300s is very interesting, but having no possibility to impact on this duration really is a pity. There should be some kind of property to fix this behaviour. So as you say, a custom provider may be the only solution.
So far, the hack I use to get this working is based on code similar to this one (it is presented here in a similar form than my test case above). Obviously, reading the /etc/resolv.conf for each dns resolution is not an option in a real environment, but you get the idea.
package com.test.dnsresolver;
import java.io.BufferedReader;
public class DnsResolver {
     private static final String urlString = "www.google.com";
     private static final String resolvConf = "/etc/resolv.conf";
     public static void main(String[] args) {
          int loopCounter = 0;
          while (true) {
               loopCounter++;
               try {
                    Thread.sleep(1000);
               } catch (InterruptedException e) {}
               // Parse the current DNS server to be used in the config
               String nameserver = null;
               try {
                    BufferedReader input = new BufferedReader(new FileReader(new File(resolvConf)));
                    String currentLine = null;
                    while (( currentLine = input.readLine()) != null){
                         // Take care of potential comments
                         currentLine = currentLine.substring(0, currentLine.indexOf("#") == -1
                                   ? currentLine.length() : currentLine.indexOf("#") );
                         if (currentLine.contains("nameserver")) {
                              // It is the line we are looking for
                              nameserver = currentLine;
                              break;
               } catch (FileNotFoundException e) {
                    System.out.println("Loop " + loopCounter + ": FileNotFoundException");
               } catch (IOException e) {
                    System.out.println("Loop " + loopCounter + ": IOException");
               if (nameserver == null) {
                    // No "nameserver" line found
                    System.out.println("Loop " + loopCounter + ": No nameserver found in configration file!");
                    continue;
               // Trim it to just contain the IP address
               nameserver = (nameserver.replace("nameserver", "")).trim();
               System.out.println("Loop " + loopCounter + ": Going to use DNS server " + nameserver);
               // At this point, we know which server to use, now perform the resolution
               Hashtable<String, String> env = new Hashtable<String, String>();
               env.put("java.naming.factory.initial", "com.sun.jndi.dns.DnsContextFactory");
               env.put("java.naming.provider.url",    "dns://" + nameserver);
               DirContext ictx;
               try {
                    ictx = new InitialDirContext(env);
                    Attributes attrs1 = ictx.getAttributes(urlString, new String[] {"A"});
                    System.out.println("Loop " + loopCounter + ": Manual resolution: +" + attrs1.get("a").get() + "+");
               } catch (NamingException e) {
                    System.out.println("Loop " + loopCounter + ": NamingException");
}So maybe I should adapt and package this into a proper provider and specify it for sun.net.spi.nameservice.provider. Any link, info or example about how a proper provider should look like?
Thanks for your advices!

Tomcat 4.1 class problem. Doesn't identify the class.

Hi
I just installed J2SDK and tomcat in windows xp. I've made jsp files and beans. The first page is customerlogin.jsp which takes user id and password in a form. It sends the request to authenticate.jsp. Would you please give me a few important steps that need to be done?

Your problem is in web.xml. Only servlet classes need to be mapped. Your bean class should not be.

Java can't find main class when manifest has certain JARs on it

I recently wrote an Ant script that builds my application and jars it up, creating a manifest in the process. The manifest specifies the main class and a classpath that mentions other jars that exist in the same directory. Everything works as expected and I am able to run the program using "java -jar abc.jar".
However, I recently started using classes in my program that come from a jar that should (according to the company I work for) reside in a central location rather than each application having its own copy. So, I changed my build script to reference those shared jars in a common location. But now when I run "java -jar abc.jar", I get a java.lang.ClassNotFoundException: com.example.Main. If I edit the jar's manifest and manually remove the new jars from the classpath, the ClassNotFoundException error goes away (although obviously that causes other problems.) Is there something about adding those new jars to the manifest classpath that would prevent Java from finding my main class? My manifest looks something like this and the last two jars (the ones with the absolute paths) are the jars that seem to be the root of the problem.
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.0
Created-By: 1.5.0_04-b05 (Sun Microsystems Inc.)
Main-Class: com.uprr.app.rsa.Main

\java\jms.jar C:\software\tibco\ems\clients\java\tibjms.jarAny ideas?
Brandon

I still don't know why giving the absolute classpath entry like that would cause Java to be unable to find the jar's main class, but I did make an interesting discovery. If I give the absolute path without the drive letter, is able to find the main class again. Something like this won't work...
Class-Path: C:\software\tibco\ems\clients\java\tibjms.jarBut something like this will...
Class-Path: \software\tibco\ems\clients\java\tibjms.jarBut I'd still like to know why Java doesn't accept drive letters when running on a Windows machine. After all, what if my manifest needed to reference a jar that was on a different drive, like a network drive (since this whole problem came up as a result of shared common jars that need to exist outside of the project.)

Eclipse doesn't recognize TomEE

According to 'TomEE and Eclipse' on Apache's website, it should be easy to run TomEE on Eclipse. I downloaded version 1.7.2 of TomEE-webproject from TomEE's download section and unpacked it in my home directory, as described in the YouTube-video on 'TomEE and Eclipse', and tested by running ~/apache-tomee-webprofile-1.7.2/bin/startup.sh. When navigating to localhost:8080, everything seems fine (the page displays "Apache Tomcat (TomEE)/7.0.62 (1.7.2)").
However, when trying to install a new server in Eclipse, by choosing New Runtime... in the new Dynamic Web Project dialog and browsing for a Tomcat 7.0 directory, I can't select the root of the tomcat-webprofile directory (Eclipse complains that "unknown version of Tomcat was specified") and 'Finish' remains grey (and a Tomcat version is suggested to download and install). Apparently, Eclipse doesn't recognize the TomEE directory as a Tomcat directory.
I'm using Eclipse 4.5.0 (Mars) in Arch Linux. Tomcat 7 and 8 installed by the system are correctly recognized.
NOTE: Sorry for not including hyperlinks, but I'm not yet allowed to post links to non-eclipse.org sites.

Marcel,
A few years ago, I took some careful notes as I made my way through some
JSF stuff. While I experienced some frustration, it was more with the
general Faces community and not at all with Eclipse. I would have said
then that Eclipse was just the table top; the different Faces proposals
(Rich, My-, etc.) were frustratingly documented, ill available, hard to
find a complete set, etc. It's not so much Eclipse's fault.
I assume you downloaded Eclipse IDE for Java EE Developers. I used just
plain Tomcat.
In any case, and I know these notes are several years old, feel free to
look through them for any help or clues you might find (bottom/middle
half of left column).

Lars Vogel's got some great tutorials on web programming including
Tomcat and JSF:

Hope this helps and doesn't confuse.

Itunes 10.6 doesn't recognize my iphone 4s 32gb, could you please help me?

ITunes doesn't recognize either of my iPods

I downloaded the latest update recently and since then iTunes doesn't recognize either of my two iPod touches (4th gen), even though the computer does. My iPad (1st gen) is still recognized normally. I tried uninstalling iTunes and reinstalling it several times, and that didn't work. The iPods are recognized by iTunes on other computers. The computer in question runs windows 8.1, if that makes a difference. From the look of these forums it looks like I'm not the only one who has this problem. Please help.
