Loading files in java

I have a swing app, which in production is executed as a jar file. I would like to load a property file as well as couple of other png's and pdf's
The directory structure is application source / package
applicaiton source / props/propertyfile.txt
application source / folder/png's & pdf's
I access the property as "props.propertyfile" and it is working. But for other files, I am able to access it while running from command line. But not from a executable jar file.

Unless you specify the full path, files are loaded relative to your running directory. So unless you are running the JAR from the "application source" folder, it won't find the file. But if you can see one file, then maybe that's not the problem. Other than that, it would be helpful if you could post the code that you're using to read the files.
Also, if you're planning on sending your JAR out into the world, then you probably should include all your resources in the JAR itself, rather than have them as separate files. It's not too hard, and then your users don't have to worry about setting up an exact file structure so that everything is found. It's just all magically included in the JAR.

How to load file using Java

Hello,
I am trying to load file into the TimesTen (csv or txt) using Java language. I tried using query "LOAD DATA INFILE ..." but I received error that there is something wrong in word "DATA", later I tried to copy solution from sample programs written in Java but I get a lot of error which i couldn't solve. I also tried to use ttBulkCp in Java like this: query = {CALL ttBulkCp ... } but it wasn't working as well. There must be a way to load data from file to the TimesTen table using script written in Java, right?
Thank you for any ideas.

If you take a look at the quickstart guide you get when you install the product you'll see a java code example called 'level3.java' which does what you want:
This program uses the TimesTen JDBC driver to perform order processing operations:
a) Connect to the database using the TimesTenDataSource interface
b) Process all orders in the input3.dat file by inserting into the ORDERS and ORDER_ITEM tables.....

How to batch load files

Hi,
I have a list of files to be read entirely into memory. Is there any better approach of reading those files, other than one-by-one approach.
Thanks

Hi,
I have this problem:
I have searched in google about Batch Load File. I understood like it should be have name value pairs of data and terminate with EOD & # sign.
I want to create a batch load file in java. So how should be the file? The file should be same as i mentioned above or else we can keep it as an xml file or what?
So how should i write the code in java i.e; what technologies i should use inorder to create a batch load file in java.
Can any one please give me a solution.
Thanks

Loading VRML 1.0 files in Java 3D

Hi all,
Does anyone have a successful experience loading VRML 1.0 file into Java 3D as a scene graph? While I think it's too complicated to write my own loader, is there any existing loader available for this task?
I've tried 2 VRML loaders, but neither seems to work. org.web3d.j3d.loaders.VRML97Loader works fine loading VRML 2.0 files, but not for 1.0 files. An exception with the following message was thrown.
Error loading VRML file: Unsupported version V1.0
com.sun.j3d.loaders.vrml97.VrmlLoader always complains about the format of my VRML files (both version 1.0 and 2.0). In this case the exceptions is...
java.lang.InstantiationError: vrml.node.Node
at com.sun.j3d.loaders.vrml97.impl.Node.wrap(Node.java:114)
OR
Exception: com.sun.j3d.loaders.vrml97.impl.ParseException: Unknown node type: Separator
Last token was "Separator" at line 5
com.sun.j3d.loaders.vrml97.impl.ParseException: Unknown node type: Separator

VRML1.0 and VRML97 (or 2.0), are very different in the structure, so it is very unlikely that a loader built for version 2.0 works for 1.0 files.
I don't know whether there is a J3D loader for 1.0.
You may try with some conversion program,
http://www.nhcad.com/old/html/vrml2.html
try this.. hope it helps.

I am getting a "java.lang.RuntimeException: Error loading file:....NULL content-length." message when attempting to load a jnlp file

I am the applications administrator for an instance of Galaxy server. In Galaxy there is an option / plugin to opne a BAM file via the Integrative Genomics Viewer (IGV) created at the Broad Institute. When invoked it downloads a jnlp file and launches IGV and then is supposed to open the BAM file in the viewer. However, when it attempts to open the BAM file I get the following error:
"An Error occurred while loading: http://galaxy/display_application/52cef830ad5766ca/igv_bam/web/29212308ff643a94/data/galaxy_52cef830ad5766ca.bam

UPDATE
Compiling from command line I found out that the class definition for oracle.oats.scripting.modules.basic.api.IteratingVUserScript is missing. Do you know what .jar file contains this class?

Executing batch file from Java stored procedure hang

Dears,
I'm using the following code to execute batch file from Java Stored procedure, which is working fine from Java IDE JDeveloper 10.1.3.4.
public static String runFile(String drive)
String result = "";
String content = "echo off\n" + "vol " + drive + ": | find /i \"Serial Number is\"";
try {
File directory = new File(drive + ":");
File file = File.createTempFile("bb1", ".bat", directory);
file.deleteOnExit();
FileWriter fw = new java.io.FileWriter(file);
fw.write(content);
fw.close();
// The next line is the command causing the problem
Process p = Runtime.getRuntime().exec("cmd.exe /c " + file.getPath());
BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line = input.readLine()) != null)
result += line;
input.close();
file.delete();
result = result.substring( result.lastIndexOf( ' ' )).trim();
} catch (Exception e) {
e.printStackTrace();
result = e.getClass().getName() + " : " + e.getMessage();
return result;
The above code is used in getting the volume of a drive on windows, something like "80EC-C230"
I gave the SYSTEM schema the required privilege to execute the code.
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'java.io.FilePermission', '<<ALL FILES>>', 'read ,write, execute, delete');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');
GRANT JAVAUSERPRIV TO SYSTEM;
I have used the following to load the class in Oracle 9ir2 DB:
loadjava -u [system/******@orcl|mailto:system/******@orcl] -v -resolve C:\Server\src\net\dev\Util.java
CREATE FUNCTION A1(drive IN VARCHAR2) RETURN VARCHAR2 AS LANGUAGE JAVA NAME 'net.dev.Util.a1(java.lang.String) return java.lang.String';
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
The problem that it hangs when I execute the call to the function (I have indicated the line causing the problem in a comment in the code).
I have seen similar problems on other forums, but no solution posted
[http://oracle.ittoolbox.com/groups/technical-functional/oracle-jdeveloper-l/run-an-exe-file-using-oracle-database-trigger-1567662]
I have posted this in JDeveloper forum ([t-853821]) but suggested to post for forum in DB.
Can anyne help?

Dear Peter,
You are totally right, I got this as mistake copy paste. I'm just having a Java utility for running external files outside Oracle DB, this is the method runFile()
I'm passing it the content of script and names of file to be created on the fly and executed then deleted, sorry for the mistake in creating caller function.
The main point, how I claim that the line in code where creating external process is the problem. I have tried the code with commenting this line and it was working ok, I made this to make sure of the permission required that I need to give to the schema passing security permission problems.
The function script is running perfect if I'm executing vbs script outside Oracle using something like "cscript //NoLogo aaa1.vbs", but when I use the command line the call just never returns to me "cmd.exe /c bb1.bat".
where content of bb1.bat as follows:
echo off
vol C: | find /i "Serial Number is"
The above batch file just get the serial number of hard drive assigned when windows formatted HD.
Same code runs outside Oracle just fine, but inside Oracle doesn't return if I exectued the following:
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
Never returns
Thanks for tracing teh issue to that details ;) hope you coul help.

Itunes wont load due to java scriptcore.dll what do i do, itunes wont load due to java scriptcore.dll what do i do

Suddenly itunes stopped loading. I uninstalled it and tried to reinstall it but it wont load saying the Java sript core.dll is not valid. What do i do to fix this? And will i be able to get my downloads back?

Taken at face value, you're having trouble with an Apple Application Support program file there. (Apple Application Support is where single copies of program files used by multiple different Apple programs are kept.)
Let's try something relatively simple first. Restart the PC. Head into your Add or Remove Programs control panel, select "Apple Application Support", click "Change" and then click "Repair".
If no joy after that, try the more rigorous uninstall/reinstall procedure from the following post. (Although the procedure is for Vista and 7 and you've got XP, just read "Computer" as "My Computer", read "Uninstall a program control panel" as "Add or Remove programs control panel" and assume the system is 32-bit, and you'll be doing the right things.)
Re: I recently updated to vista service pack 2 and I updated to itunes 10.2.1 and ever

Could not load file/URL (file not found) error for JNLP file

I am completely baffled in trying to figure out why I am getting the following error for some JNLP files but not others:
Error: could not load file/URL specified: C:\Users\tom\AppData\Local\Temp\javaws2
java.io.FileNotFoundException: C:\Users\tom\AppData\Local\Temp\javaws2 (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)

at com.sun.javaws.Main.continueInSecureThread(Unknown Source)
at com.sun.javaws.Main$1.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)I have Googled around this forum and elsewhere, and have seen reports that this error is IE-specific, and seems to have something to do with no-cache headers being sent, or with the client browser's cache being full or turned off (which is not my case). I saw the information in the JavaWS FAQ, which recommended turning off security constraints for the JNLP's URI. I tried that, and it didn't help. One of the very baffling things is that I have created several variations of the JNLP file, with varying combinations of jars and property resources, and some combinations always work while other combinations never work. Here's an example:
<jnlp spec="1.0+" codebase="$$codebase">
   <information>
      <title>demo app</title>
      <description>illustrates weird bug</description>
   </information>
   <resources>
      <j2se version="1.5+"/>
      <jar href="randomFile.jar"/>
      <property name="xxx" value="xxxx"/>
      <property name="swing.metalTheme" value="steel"/>
   </resources>
</jnlp>The above file always fails with the error shown at the top of this message. However, if I remove either of the two properties, it works fine. And I have created other variations with lots of properties, some of which work. All of these variations are in the same directory in the war file, served by the exact same servlet (a slightly modified version of the jnlp.sample.servlet.JnlpDownloadServlet provided with JDK 1.6.0_3). Assuming that a no-cache header is the problem, what on earth could be causing some JNLP files to always be served with a no-cache header, while others are never served with a no-cache header?
On a related note, any recommended debugging techniques for seeing what headers are being transmitted? I tried adding a simple check for a "debug=true" parameter in the servlet that causes it to set the content type to "text/plain" instead of JNLP, and that allows me to see (rather than execute) the JNLP XML that's being returned, but it doesn't show me the HTTP headers that are being sent back. If any caching headers are being set, I think it must be being set by the servlet container itself, as it's nothing being set in the servlet code that I can see. So I don't see any way on the server side Java code to output or log the actual HTTP response (or is there?). Any tips in that regard much appreciated.

Hi Luca-Sanna,
Thanks for the response. Re browsers, yes, it fails in IE but it succeeds in Firefox. The info on the JavaWS FAQ and other places all seem to indicate that it's an IE issue concerning handling of the cache-control headers.
I should check in my webserver forum (Sun WebServer 7) to see about logging options. Sniffing on the client side is not possible, as my app is required to use HTTPS exclusively, and unfortunately that also precludes a telnet GET request.

Error trying to open a file using java.io.* in an Applet

I have a file called wordlist.txt and I am using java.io.* to open it. When I try it
in Applet Viewer it runs without a hitch. But when I try to run it in a
browser as an Applet, it errors out saying:
com.ms.security.SecurityExceptionEx[package3/SpellCheck.setWordList]: cannot access file wordlist.txt
I have tried adding this file to my Project and accessing it that way but I still get
the same message. If anyone can help with this, I sure would appreciate it.
My code is as follows:
String inWord = new String("zzz");
try {
File myWordList = new File("wordlist.txt");
BufferedReader inWordList = new BufferedReader(
new FileReader(myWordList));
inWord = inWordList.readLine();
while (inWord != null) {
wordList.addElement(inWord);
inWord = inWordList.readLine();
} // end while
inWordList.close();
} // end try
catch (Exception e1) {
// Pr is equivalent System.out.println();
Pr("Error Reading this line " + '\n' + inWord + '\n' + e1);
} // end catch
} // end setWordList()

Applets are generally prevented from reading as well as writing files, but appletviewer can load files from the hard drive, so, that is the cause of the behaviour you have observed. To know more about enabling applets load files, you have to sign your applets,
