Read from a property file which is in a zip
I have the problem, that I can�t read a property file in a zip. A class which I ca get in the same zip needs this property to init.
I call this in a batchfile.
The message is like:
c:/xx/core.zip!/com/xx/Prop.properties
Path of the zip Path of the Property in zip
Syntax or name or path are not correct.
Where is the problem?
Thanks in advance
Frank
hm, am not sure I follow but
it is not possible to instantiate the class. I only use this class. >Java will find the class in the same zip and path, but the property->File will not be loaded while a FileInputStream wonts to open it.FileInputStream can't be used to open a zipped file, you can get an InputStream from the ressources variable by using URL.openStream method and feed this into Properties.load
if you post some code here that you are able to change, then people might be able to help more :)

Hi i am trying to write a program which reads from a properties file the pr
hi,
this is ayesha.
I am trying to write a program wherein i will be reading the value of a property from a properties file which will be true initially. I want to loop in there till the time when the value of the property is false.
The code is as follows:
public static void main(String[] args) {
ReadingAPropertiesFile propers=new ReadingAPropertiesFile();
propers.ReadingFileRegularly("F:\\ayesha.properties");
public String ReadingFileRegularly(String FilePath){
Properties props = new Properties();
String message;
String filePath=FilePath;
try {
props.load(new FileInputStream(filePath));
message = props.getProperty("ayesha");
boolean theValue = Boolean.parseBoolean(message);
while(theValue){
System.out.println("trueeeeeeeeeeeeeeeeeeeeeee");
Thread.sleep(60000);
ReadingFileRegularly(filePath);
catch(Exception ex){
ex.printStackTrace();
String messagean="something";
return messagean;
The contents of ayesha.properties are :
ayesha=true
After 5 minutes it will be set to false so i want to loop in there till the value of ayesha=false at which time i will return
But i dont know how to loop in there for that time:
while(theValue) ?????????????/ what after this???????????
Any suggestons are awaited.ayeshaparween wrote:

Any suggestons are awaited.I think you better rethink your design , do not use recursion, I would normally use a loop like you did but without loading the content of the file each time, I would use File.l lastModified() method and compare with previous results from this method to see if the file was modified. Then if it was modified then load the new File and check if the property value has changed. -
Read from a config file in File Adapter in SOA Suite 11g
I want to read from a config file in order to determine whether to archive or delete the file after processing using file adapter in SOA Suite 11g. How do i do that.
only part i replied on was the part of how to read a file
but i think in your case you could do the next
use the sync file adapter to read in the file during your process
based on this content you set a variable "myOutputDirectory"
then create a file adapter (write) which will store the file on file system

and use that (jca.file.Directory) property to store the file either on the archive location or the delete location -
How can i get the all values from the Property file to Hashtable?
how can i get the all values from the Property file to Hashtable?
ok,consider my property file name is pro.PROPERTIES
and it contain
8326=sun developer
4306=sun java developer
3943=java developer
how can i get the all keys & values from the pro.PROPERTIES to hashtable
plz help guys..............The Properties class is already a subclass of Hashtable. So if you have a Properties object, you already have a Hashtable. So all you need to do is the first part of that:Properties props = new Properties();
InputStream is = new FileInputStream("tivoli.properties");
props.load(is); -
I work for Office Depot, in the tech department. Basically, one of our associates was supposed to do a data backup, and re-install Windows 7, then transfer the files back. He used Windows Easy Transfer and compacted everything into a 163 GB file.
Now comes the hard part. When we try to put it back on his computer ((drag-and-drop to the desktop) which has been wiped back to factory settings using the recovery partition), it stops at 79.5 GB remaining (you know how it doesn't give you a % of completion,
it just shows how many GB are remaining) and then says "Can't read from the source file or disk" and gives you an option to try again, or cancel. It gets hung up on the same point each time.
Normally, this wouldn't be a huge issue, but the contents on the drive are his wife's architect blueprints and interior design stuff, along with wedding photos, etc, which are the only copies they have. On top of those, they have court documents and other
important files that we are unable to access now.
I wasn't involved with this transfer, so I'm trying to clean up the mess as best I can. I remembered that the customer's wife was Russian, and had some files typed with a Russian keyboard, so on and so forth. I wonder if that's the issue? If not, I really
have no idea how to manually extract things from a ".mig" file, or how to diagnose what area is potentially corrupted.
In light of this situation, we tried using "Recuva" to recover the files post-wipe, but everything was corrupted or unable to be opened, and it also extracted and recovered all of the "useless" photos, such as the skype logos, up and
down arrows for browsers, etc (it was 160,000+ photos).
Trying to avoid a potential lawsuit, unhappy customer, and costing the company lots of money to see if professionals can get into this external hard drive.
Other relevant information:
We used a Toshiba 500 GB (465 GB) external hard drive.
Customer's computer is an HP Pavilion P6000 Series (Model No. p6520y) running Windows 7 Home Premium 64-bit Service Pack 1.
Any other information that is needed can be provided, thanks in advance, and hopefully we can find a solution to this issue quickly!
-JohnI think there's a lack of understanding somewhere.
"If you even can't start the process, please unplug it from your new PC. Then head back to your new computer and plug
the external drive back in to your new computer. "
Unplug from new, head back to new, plug it back in? That doesn't make much sense! Haha.
I knew what you meant though, somewhat. When I search through the drives after clicking yes (Has windows easy transfer
already saved your files blah blah blah) I click on the transfer file and it says "Windows Easy Transfer could not open the file".
Rather than drag-and-drop the file to the desktop, I now tried to double-click on the file itself while it was plugged
into the computer. It opened, and it started transferring until it was about 70% completed, and then an error popped up saying "WET can't open the easy transfer file, make sure your USB device is plugged in or check your internet connection".
I checked, and the USB hard drive's light wasn't on. Now, I unplug it and plug it back in, and the light comes back on,
so I click Retry, and it resets the bar back to nothing and says "Transfer time: 1 minute".
Rather than continue trying, I clicked "Cancel" instead of Retry, and it says "Your transfer did not complete successfully."
It says to click "view report" for more information, but there's no "view report button".
At the moment, I am scanning the External Drive for bad sectors using the check disk tool in properties. It's frozen
at "0 USN bytes processed". -
Maven Plugin not accepting values from a property file.
Hi,
I want to create javadocs using maven.
It works fine when i provide all the absolute paths in the pom.
But when i try to provide paths by reading a property file then the maven-javadoc-plugin does not get the paths from this property file.
The property file is defined as mentioned in below format:
src_mvn_consult_framework_dir=/var/lib/hudson/jobs/CZ_NAB_CORE_MVN_CHECKOUT/workspace/middleware/projects/framework
src_mvn_consult_module_dir=/var/lib/hudson/jobs/CZ_NAB_CORE_MVN_CHECKOUT/workspace/middleware/projects/module
src_mvn_consult_appx_dir=/var/lib/hudson/jobs/CZ_NAB_CORE_MVN_CHECKOUT/workspace/middleware/projects/appx
src_mvn_consult_client_dir=/var/lib/hudson/jobs/CZ_NAB_CORE_MVN_CHECKOUT/workspace/middleware/projects/client
src_mvn_consult_app_webservice_dir=/var/lib/hudson/jobs/CZ_NAB_CORE_MVN_CHECKOUT/workspace/middleware/application/com.ofss.fc.cz.nab.webservices
src_mvn_consult_app_middleware_dir=/var/lib/hudson/jobs/CZ_NAB_CORE_MVN_CHECKOUT/workspace/middleware/application/com.ofss.fc.cz.nab.middleware
Calling this property file in the pom like:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>properties-maven-plugin</artifactId>
<version>1.0-alpha-2</version>
<executions>
<execution>
<phase>initialize</phase>
<goals>
<goal>read-project-properties</goal>
</goals>
<configuration>
<files>
<file>/var/build/consult/maven/cz_javadoc-config.properties</file>
</files>
</configuration>
</execution>
</executions>
</plugin>
Finally we are using keys defined in property file in pom like:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-javadoc-plugin</artifactId>
<version>2.7</version>
<configuration>
<sourcepath>${src_mvn_consult_framework_dir};
${src_mvn_consult_module_dir};
${src_mvn_consult_appx_dir};
${src_mvn_consult_client_dir};
${src_mvn_consult_app_webservice_dir};
${src_mvn_consult_app_middleware_dir};
</sourcepath>
</configuration>
</plugin>
Please suggest how we can get the value of keys defined in the property file in POM
Thanks for your invaluable supportI've had to do something similar in one of my apps. In order to populate values in the THIS scope, you'll need to put a copy of the XML loading/processing logic in the pseudo-constructor (or encapsulate it in a separate CFM/CFC file and include it in both places). It's ugly, but that's the only way I'm aware of to access the THIS scope.

Problem with ArrayLists and writing and reading from a .dat file (I think)
I'm brand new to this forum, but I'm sure hoping someone can help me with a problem I'm having with ArrayLists. This program was originally created with an array of objects that were displayed on a GUI with jtextFields, then cycling thru them via jButtons: First, Next, Previous, Last. Now I need to add the ability to modify, delete and add records. Both iterations of this program needed to write to and read from a .dat file.
It worked just like it was suppose to when I used just the array, but now I need to use a "dynamic array" that will grow or shrink as needed: i.e. an ArrayList.
When I aded the ArrayList I had the ArrayList use toArray() to fill my original array so I could continue to use all the methods I'd created for using with my array. Now I'm getting a nullPointerException every time I try to run my program, which means somewhere I'm NOT filling my array ???? But, I'm writing just fine to my .dat file, which is confusing me to no end!
It's a long program, and I apologize for the length, but here it is. There are also 2 class files, a parent and 1 child below Inventory6. This was written in NetBeans IDE 5.5.1.
Thank you in advance for any help anyone can give me!

Its a dumb question, but with NetBeans how do I find out which reference could be null? I'm not very familiar with how NetBeans works with finding out how to debug. Any help you can give me would be greatly appreciated.The IDE is com-plete-ly irrelevant. It's all about the source code.
Do you understand anyway when and why a NullPointerException is been thrown? It is a subclass of RuntimeException and those kind of exceptions are very trival and generally indicate an design/logic/thinking fault in your code.

someObject.doSomething(); // Invoking a reference which is null would throw NPE. -
How to load data from a flat file which is there in the application server
HI All,
how to load data from a flat file which is there in the application server..Hi,
Firstly you will need to place the file(s) in the AL11 path. Then in your infopackage in "Extraction" tab you need to select "Application Server" option. Then you need to specify the path as well as the exact file you want to load by using the browsing button.
If your file name keeps changing on a daily basis i.e. name_ddmmyyyy.csv, then in the Extraction tab you have the option to write an ABAP routine that generates the file name. Here you will need to append sy-datum to "name" and then append ".csv" to generate complete filename.
Please let me know if this is helpful or if you need any more inputs.
Thanks & Regards,
Nishant Tatkar. -
Why can't I download my already purchased music and other files from iCloud, even though I owe money to iTunes for my most recent purchases. Doesn't seem right that they keep me from accessing those files which I've already paid for!
- Are you saying that they are not listed in your Purchased section?
Downloading past purchases from the App Store, iBookstore, and iTunes Store
- Are they listed in your Puchases history when you log into your account on your computer?
- Are they still available now for purchase? If not then you are out of luck
If they are still available and listed in your Puchase History then contact iTunes

Crystal Report that reads from an XML file Datetime or Date
I have a Crystal Report 2008 that reads from an XML file, the source File XML Date data looks like this: 2008-03-10
But the Crystal Report interpreted by datatime, I need the Crystal Report to look like this: 2008/03/10 (date) not 2008-03-10T00:00:00-05:00 (datatime)
Look at an example (source file xml, report, and parameter file to execute report) at url: http://www.5websoft.com/sample.zip
Import the file in the design and will to verify that interpret incorrectly the fields of type date as datetime
not mapped currently for fields..
Help.....
Thanks!You could always reformat the field to only display the date portion:
Format Field > Date and Time tab; choose the date style you need here.
Or create a formula to extract just the date and use this field in your report:
date({table.field}) -
HOW TO WRITE AND READ FROM A TEXT FILE???
How can I read from a text file and then display the contents in a JTextArea??????
Also how can I write the contents of a JTextArea to a text file.
Extra Question::::::: Is it possible to write records to a text file. If you have not idea what I am talking about then ignore it.
Manny thanks,
your help is much appreciated though you don't know it!Do 3 things.
-- Look through the API at the java.io package.
-- Search previous posts for "read write from text file"
-- Search java.sun.com for information on the java.io package.
That should clear just about everything up. If you have more specific problems, feel free to come back and post them. -
How to read from a text file one character at a time?
Hello
I wish to read from a text file in a for loop and that on every iteration i read one charachter and proceed to the next one.
can anyone help me?

Some additional comments:
You really don't want to read any file one character at a time, because it is highly inefficient. More typically, you read the entire file into memory with one operation (or at least a large chunk, if the file is gigantic) and then do the rest of the operations in memory. One easy way to analyze it one byte at a time would be to use "string to byte array" and then autoindex into a FOR loop, for example.
Of course you could also read the file directly as a U8 array instead of a string.

Getting repeated values when reading from a text file.
I need to read from a text file. When the token encounters a particular word (command) I need to read the next line and perform some actions. However, this part is working but it is repeating the values again and again until it encounters the next particular word (command). Hope that someone will help me out, as always when I posted a problem in these forums.

The information in the text file is as follows:
membera
Hillman
membera
Skoda
membera
Honda
membera
Toyota
and the result is:
[0] Hillman
Number of set members: 1
[0] Hillman
[1] Skoda
Number of set members: 2
[0] Hillman
[1] Skoda
[2] Honda
Number of set members: 3
[0] Hillman
[1] Skoda
[2] Honda
[3] Toyota
Number of set members: 4
instead of just one set:
[0] Hillman
[1] Skoda
[2] Honda
[3] Toyota
Number of set members: 4
Hope it is easier to understand like this.
