File explorer java code

Hi, I need to write a windows-explorer-like File Explorer panel. Could anyone point to me some sample code?
Thanks,
autogoor

I did not try it yet, but you could use the NetBeans platform as a base for your application (includes file access via file explorer).
Source code is available at:
http://www.netbeans.info/downloads/download.php?a=b&p=2
Or, maybe, a simple JFileChooser would do it ?

please help me
Thanka in advance
Ravi Charan

The second address given to that function, does it relate to the class that its being called from? cause i've got
Runtime.getRuntime().exec("C:\\WINDOWS\\hh.exe .\\HelpFile_9_3.chm" );where HelpFile_9_3 is in the same folder as my class, but it won't work. Can anyone help?
Also, can you search within a chm file from Java? If I get that above code working, I presume it'll open the help file to the main page. I'd like to search within that document for a word or phrase - possible?
Thanks!

Starting exetutable java file from java code

Hi I was wondering how I can start a executable java file from java code?
thanks

Hi Mkaveli,
Yes, it's possible. If you have a JAR executable, you've just to call the main method of its starter class. For a simple executable class, just call its main method.
This way :
SomeStarter.main(null); // if there's no argumentSmall precision : the executable JAR or class must be specified in the classpath of your application.

How to modify an existing xml file from java code.

Hi
I have worked on creating a new xml file from java code using xmlbeans.But if i try to modify an already existing file using java code I am unable to get errorfree xmlfile.
For example if xml file(studlist.xml) is as below:
<?xml version="1.0" encoding="UTF-8"?>
<StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
     <Student>
          <Name>ram</Name>
          <Age>27</Age>
     </Student>
<Student>
          <Name>sham</Name>
          <Age>26</Age>
     </Student>
</StudentList>
Now suppose i have set name to victor using student.setName,
and set age to 20 using setAge from javacode,
the new xml file is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
     <Student>
          <Name>ram</Name>
          <Age>27</Age>
     </Student>
<Student>
          <Name>sham</Name>
          <Age>26</Age>
     </Student>
</StudentList>
<Student>
          <Name>victor</Name>
          <Age>20</Age>
     </Student>
As observed this is not a valid xml file.But how can i modify without any errors?

I know it's an old post, but I found this while doing a google search for something else, and don't like to leave it un-aswered
Just in case anyone has a similar problem... In this case the new elements have been appended outside of the root element
What you need to do is first get the root element and then append the new children to that, there are several ways of getting the root element, which depend on what you want to do with the elements you get back here's a simple (incomplete) way.
// gets the root element of the specified file (code not shown)
Element rootElement= new SAXReader().read(file).getRootElement();Then just append the new elements as below (this is non-generic code and would need to be modified for your situation)
// write a new student element
Element student = document.createElement("Student"); // creates the new student
rootElement.appendChild(student); // ***appends it to the root element***
Element name = document.createElement("Name"); // creates the name element
name.appendChild(document.createTextNode("Fred")); // adds the name text to the name element
student.appendChild(name); // appends the name to the student
Element age= document.createElement("Age"); // creates the age element
age.appendChild(document.createTextNode("26")); // adds the age text to the age element
student.appendChild(age); // appends the name to the studentThen flush ya buffers or whatever and write the file

Ah, sorry, strike that. You want multiple files. I think the easiest way is to simply parse with DOM. [http://www.w3schools.com/xpath/default.asp] . And here [http://www.w3schools.com/xpath/default.asp].
You can output the various XML elements using a PrintWriter or creating a separate DOM document for each file you want to create and serializing that.

How can I using functions implicit in dll file in java code ?
I'm developing a program that interfacing with fingerprint hardware.
I have the finger print already, and I have to the SDK that have all functions for managing this fingerprint.
These SDK functions are represented in dll files.
I want to know how can I use these functions in java code .

After reading a lot of articles, tutorials, and overviews about JNI (Java Native Interface)
I found that these steps
1.     Develop the Java code
2.     Compile the Java code to a class file
3.     Generate the header file
4.     Implement the native method
5.     Create the shared library or DLL
6.     Run the Java program
Is the common steps in JNI development
The most powerful link was
http://java.sun.com/docs/books/jni/html/start.html
and
http://www.netbeans.org/kb/55/beginning-jni-part2.html
and the pdf oh this link
http://www.ibm.com/developerworks/edu/j-dw-javajni-i.html requiring IBM registration to download it.
But I have already the DLL, and want to the stright forward way to use its functions by java code only.
I don not to write any C++ code .
Is this possible???????????????????????????????

OpenScript/How to add .jar file to Java Code in relative path

Hi all,
I want to add a .jar file which can be executed separately (like "java -jar A.jar") to my recorded Java Code.I've read this wiki http://everest2.us.oracle.com/wiki/Generic_JAR_Project about how to add a .jar file to "Assets", however, I cannot figure out how to use the .jarr file in Java code,I mean , how to get this .jar file like the method the databank added in "Assets"?
Things I did are as followed:
1.Execute my .jar file in OpenScript Java code with absolute path like this:
String cmd = "C:\Users\A.jar";
Runtime.getRuntime().exec(cmd);
This does work, but must set a absolute path in Java code like "C:\User\A.jar" ,which is not the workaround I want (I need my scripts can be run on other machines).
2.Try to get its current path with following codes:
File directory = new File(".");
String currentPath=directory.getCanonicalPath();
However,though this can get its absolute path (which is the the project path) in Eclipse like "C:\Users\Workspace\testProject", this only gets "C:\OracleATS\openScript" in OpenScript.
I thought to copy my .jar file to the project path , got its current path in java code first,then can know the path of .jar file, but this workaround failed because of the above reason.
I notice that in the "Assets" there are "Databanks","Object Libraries","JAR Files","Scripts". Since the databanks and scripts that added to "Databanks" and "Scripts" can be got or run in Java Code like:
*getDatabank("DatabankName").getNextDatabankRecord(); String data = eval("{{db.DatabankName.data}}");*
*or getScript("ScriptName").run();*
*Is there a method to get and run the jar file added to "Assets\JAR Files" like the above?*
Thank you very much!
Regards,
Angyoung

Hi DM,
Thanks for your reply!
I've found a workaround,which is calling OpenScript's APIs ,such as this.getScriptPackage().getRepository() and this.getScriptPackage().getWorkspace(),etc to locate the .jar file.
And this workaround can still work even though the script is run on other machine.
Sorry to reply you so late!
Regards,
Angyoung
