Problem writing metadata to TIF file on Linux only - Java Discussion Boards

Hi All,

Anyone could you please explain me how to implement the Rest API which is like
"http://localhost:8080/www.example.com/{ping}/{hello}"

And how to implement in Java where the class extends ServerResource.

Regards,
Geetha.

i don't know

how to create a chart from a database in android eclipse ..
Thanks.
please I'm the project as an example
thanks ...

See http://www.codeproject.com/KB/android/[^] for many samples.

thank you very much..

1. Learn basics of java
2. Learn basics of databases
3. Learn basics of eclipse
4. Learn basics of access database via java.
5. Design application
6. Find java library that does charts. Learn how to use it.
7. Write application
8. Learn basics of Android programming
9. Learn basics of 'using' database on Android
10. Write Android application.

Step 9 might actually involve learning serving programming which involves several other steps.

You missed step 0: don't post the same question in four places on the same site! D'Oh! | :doh:

I wrote some code to insert custom annotations into a TIFF file, but I am having two problems.

First, the annotation description does not appear to be written correctly to the TIFF file, though the value is fine. I used AsTiffTagViewer to inspect the file, so it is possible that program does read descriptions for custom metadata.

Secondly, and this is more important, the exact same code does not work on Linux (runs w/o error but the annotations are not written). It runs fine on Windows 7. Below is a list of the jar files I have tried adding to the class path:

imageio-ext-tiff-1.1.10.jar
jai_codec.jar
jai_core.jar
jai_imageio-1.1.jar
mlibwrapper_jai.jar

Any help w/ these two issues would be appreciated. The code is below (assume a multi-page TIFF with 3 embedded images).

Thanks in advance!

You need to provide more information about exactly where the error lies, what information should be written to the file and what is being written.

Thanks for your response. As I said, there is no exception thrown in the code ("runs w/o error"). The problem is that the custom metadata isn't being written to the destination file (output.TIF). In the example above that would be the FirstName and LastName ("Arthur Dent", "Ford Prefect", "Zaphod Beeblebrox"). Sorry I wasn't more explicit.

Sorry, but you really need to provide more than that. I can only assume there is either a bug somewhere in your code, or an incompatibility with a library. The only way to narrow it down is to do some debugging.

This is resolved. I was missing a library or had the wrong version.

/*
 * I am trying to write a program for school children
 * or anybody that needs help or wants to refresh their English grammer.
 * The program will display a sentence on the screen, and ask the user to pick the nouns in the sentence.  If they correctly pick
 * the noun(s), they will prompted with something like, "Excellent Job!", if not they will be prompted to try again.  This basic program
 * displays the sentence, and ask the user to find the noun.  If the user correctly identifies "one" noun, it displays,
 * You are correct, the two nouns are boy and store.
 * If the user does not provide the correct answer, it displays
 * "No, that is not correct".
 * I want to put a loop in here that will keep asking the user to try again until "all" the nouns are found.  Also, how do I
 * modify the program, so when the user inputs "one" noun, the program displays, that there are more nouns, and keeps
 * prompting the user to find the remainder of the nouns.
 *
 * I started this small project to help my daughter and some of her classmates that are having difficulties with "nouns",
 * "pronouns", "verbs"....etc
 * Once I get a good understanding of this code, I will expand to pronouns, verbs, adverbs,etc...
 *
 * The program is in "Two Parts"...the first part I used a String Array...for the second part I used nested if loops.  No special
 * reason for the "two part" program.  I am trying to learn as I go along, that is the reason for trying different methods.
 *
 * Any help anyone may be able to provide will be greatly appreciated.  You may also contact me via my personal email
 * at:
 * Once again, Thank you for your help.
 * One more thing, I used Eclipse Luna to write and compile this program.

                     System.out.println("Remember that a 'proper noun' is the NAME of the person, place or thing.");
                    // userInput= userInputScanner.nextLine();
                 }

        }

     }

    }

You should probably start by creating some lists, or arrays, or even a new class, that contain entries for each sentence, and its associated keywords, that you wish to display. Each entry should contain the sentence and the nouns, something like:

{
    { "The boy went to the store", "boy", "store" },
    { "The yacht sailed the ocean", "yacht", "ocean" }
};

You can then loop through your list (or select entries at random) and post the question, and compare responses to the set of nouns following each sentence. You can then add more entries with greater levels of complexity with only minor modifications to your actual executable code.

how to get auto print jasper report in java
thankyou

What does the "auto" part mean?

If you mean a scheduled report, one that runs every day, for example, at a certain time then you find a scheduler library. And that has nothing to do with the report itself. However it does mean that something (like a service) must be running all the time so that when the appointed time arrives it can detect the time.

no no.'auto' mean, I want print a report after only click enter button.think about point of sale(POS) system.cashier can print receipt without select printer.I mean how to set my jasper report like that.

float or double depend on the range of money

No, you should never use floating point types for money.

See https://docs.oracle.com/javase/tutorial/java/data/numberclasses.html[^]. And be aware that the use of float or double types should never be used to hold money values.
