Java files from a EAR file

I want to read all Java files from a EAR file and from inner (inside EAR) EAR or WAR file with out unpacking.
suppose "Demo.ear" contaions the following files:
abc.java
programs / a.java
programs / b.java
src / index.java
src / com / myFolder / main.java
src.war
and suppose "src.war" again contains some java files inside differenet folders.
The main problem is that i can read all java files from "Demo.ear" but unable to reading from "src.war" b'coz my program is using JarFile class constructor which needs a archive file path, So only top level archive having the path but not the inner archives.
So, pls help me out to this problems
Thanks in advance

please help me
I am waiting for ur response
thanking you

Maybe you can use java.util.zip.ZipInputStream to
open the Ear and recursively to open the files in
it; I'm not sure whether this will result in a full
unpacking of the file in some temporary directory,
though.
Please let me know if it worked the way you wanted,
I'm curious about it.This jerk just created the third thread about the same topic, because he didn't understand your suggestion, which I already provided earlier.

Firstly Sorry to writing long letter. but i was unable to express my problem.
see my code==============================
JarFile jarFile = new JarFile("Demo.ear");
Enumeration e=jarFile.entries();
while (e.hasMoreElements())
JarEntry entry=(JarEntry)e.nextElement();
if (entry.getName().endsWith(".war"))
// Then what Next to do...........
===========================================
you have mentioned "theFile" , What is this?...............
InputStream in = theFile.getInputStream(theEntryOfTheWAR);
This line is not a compatible type casting in Java..........
ZipOutputStream theWar = new ZipInputStream(in);

Extracting file from a TAR file with java.util.zip.* classes

Is there a way to extract files from a .TAR file using the java.util.zip.* classes?
I tried in some ways but I get the following error:
java.util.zip.ZipException: error in opening zip file
at java.util.zip.ZipFile.<init>(ZipFile.java127)
at java.util.zip.ZipFile.<init>(ZipFile.java92)
Thank you

download the tar.jar from the above link and use the sample program below
import com.ice.tar.*;
import java.util.zip.GZIPInputStream;
import java.io.*;
public class untarFiles
     public static void main(String args[]){
          try{

               System.out.println(e.getMessage());
     private static void untar(String tarFileName, File dest)throws IOException{
          //assuming the file you pass in is not a dir
          dest.mkdir();
          //create tar input stream from a .tar.gz file
          TarInputStream tin = new TarInputStream( new GZIPInputStream( new FileInputStream(new File(tarFileName))));
          //get the first entry in the archive
          TarEntry tarEntry = tin.getNextEntry();
          while (tarEntry != null){//create a file with the same name as the tarEntry

SCA from an EAR file

Hello!
I have a simple question about the sapmake utility. I have used to create an SCA from various archives and am familiar with its workings.
What I want to know is that is it possible to create an SCA from an EAR file. I have created an SCA from an EPA and an EAR file but I want to create an SCA from an EAR.
Theoritically this should be possible because an EAR is considered to be an SDA. Since an SCA is used to pack multiple or a single SDA(s), it should be possible to create a valid SCA out of an EAR.
But when I tried it, the SCA build process went perfectly and I did get an SCA. The JSPM however, does not recognize this SCA at all! It says the inbox is completely empty. However, when I pack in the EAR with an EPA coverted to SDA and create an SCA, this SCA is immediately recognised.
So why cant I create a valid SCA from only an EAR file?
Thanks for looking into it!
Sameer

Hello Praveen!
The EAR file is considered to be an SDA by NetWeaver. This is the reason that you can add an EAR file when deploying from the SDM tool even though the button in the deployment says "Add SDA/SCA for deployment".
Bye!
Sameer.
P.S - Here is the link to one weblog which explains it - <u>Software Deployment/Component Archive Basics>.

Retrieve the jdev project from the ear file

I have an ear file, but I've lost the original jdev project.
How can I retrieve the project from the ear file?
I would know if there's a function in jdev or with another tool to convert an ear file to the original project in jdeveloper.
Thanks.

Try the File->Import menu option.

Reading an xml file from a jar file

Short question:
Is it possible to read an xml file from a jar file when the dtd is
placed inside the jar file? I am using jdom (SAXBuilder) and the default
sax parser which comes with it.
Long Question:
I am trying to create an enterprise archive file on Weblogic 6.1. We
have a framework that is similar to the struts framework which uses it's
own configuration files
I could place the dtd files outside the jar ear file and specify the
absolute path in an environment variable in web.xml which is
configurable through the admin console.
But I want to avoid this step and specify a relative path within the jar
file.
I have tried to use a class which implements the entityresolver as well
as try to extend the saxparser and set the entity resolver within this
class explicitly, but I always seem to sun into problems like:
The setEntityresolver method does not get called or there is a
classloader problem. i.e. JDOM complains that it cannot load My custom
parser which is part of the application
Vijay

Please contact the main BEA Support team [email protected]
They will need to check with product support to determine
the interoperatablity of Weblogic Server with these other
products.

Reading a Compressed File from a ZIP File, which is an entry of ZIP File

Hello, Experts,
Would it be possible somebody to help me with code example for the following problem?
I want to read a compressed file from a ZIP file, which is an entry of ZIP File, without extacting/writing files on file system. Is this possible?
Lets say we have a ZipFile1. There is ZipFile2 inside ZipFile1. And inside ZipFile2 is FileA. The scenario is reading FileA without extracting on file system.
Thank you in advance for your help.
Cheers
RADY

The classes you want to be using are java.util.zip.ZipInputStream and and ZipEntry from the same package. Construct the ZipInputStream with the input you have for the outer zip. Loop with ZipInputStream.getNextEntry until you find the inner zip you're looking for - that method returns a ZipEntry, and you get the name of the zip entry with ZipEntry.getName. Read the ZipInputStream from that point into some buffer, and read that buffer into a new ZipInputStream - rinse and repeat until you have the contents of the file in the zip in the zip...

ClassNotFoundException trying to load classes in a .war file inside an .ear file

Hi. I've deployed an EJB2 enterprise app as an ear file on WebLogic 6
          without errors. The ear file contains web app and ejb components in war and
          jar files. The web component is set to be the default web app in the
          config.xml file. Everything deploys without error messages.
          My problem is that I get ClassNotFoundExceptions when I try to invoke a
          servlet (via its servlet-mapping) or do Class.forName() on any class file in
          the war file.
          I see in '.wl_temp_do_not_delete' that the ear file has been decomposed into
          the ejb jar and web war files. The war file is not 'exploded' into a
          directory structure, however (as the console.war is). Is this an error
          (should the class packages in the war file be 'exploded'?)
          I don't see a tag in the web.xml, config.xml, or application.xml that tells
          the server to explode the war file--is there one?
          Note that if I manually copy the exploded class folders into the
          '_tmp_war_myserver_myserver_<<webappname>>' directory (and not, curiously,
          into a WEB-INF/classes subdirectory of that directory), the servlets and
          other classes load correctly. Also, jsps and html files load just fine
          without exploding the war file.
          Note also that the server complains about not being able to find the
          classes, even though it reports that the decomposed war file is in the
          classpath. Is there a problem loading class files from a .war file (because
          the namespace is different, with root classes located in WEB-INF/classes
          rather than the .war file's root?)
          Also, in the application.xml file, what is the meaning of the
          <context-root></context-root> element? What should its value be? What if
          you leave it blank?
          Thanks for any help,
          Reid


Is there a way to add jar libraries to the Oracle JVM CLASSPATH? Is this the same as the system's CLASSPATH env. variable?
Thank you!
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Alex McClennan ([email protected]):
The package prefix in the code extract was correct - i.e. "oracle.aurora.jndi". A value of "oracle.aurora.jndi.*" would be incorrect.
The problem is that the context factory implementation specified (com.evermind.server.ApplicationClientInitialContextFactory
) can't be found, the mostly likely reason being that the library containing the class isn't on the classpath.

Executing .jar files from another .jar file.

How would I run one .jar file from another .jar file. and is there anyway to call specific class arguments? Because I have one .jar file that reads a specified file and returns its contents.
So how would I execute it and specify its arguments and how would I make it return something to the executing jar file?

Because I have one .jar file that reads
a specified file and returns its contents. Presumably you have a class that does that, and you have that class stored in a jar. And you want to know how to... um... do something with that class. I say "um..." because normally you don't execute a class, either, you either call its static methods or you create an instance of the class and call its instance methods.
If you have been writing a whole lot of little classes each of which just has a static main method, then stop doing that. Write real Java classes instead. The tutorial is here:
http://java.sun.com/docs/books/tutorial/java/index.html

Is there a way to run a script to create an RPD file from MDS XML files

We would be interested in using the MDS XML format for the RPD file in saving it in our Subversion source code control system, and I have seen how to do this in the User documentation.
Our question is whether or not there is a way to use a command line tool to recreate the rpd file without having to use the Admin tool, so that we can automate the deployment of the RPD file from source code control to QA and Production environments.
If we check in the RPD file directly, then there is a way to automate the process, but we would prefer to use the MDS XML format since this allows us to save changes in text format, not binary, but we still need to be able to automate the process.
In the Oracle Fusion Middleware XML Schema Reference for Oracle Business Intelligence Enterprise Edition document, I have found that there is a way to automate the creation of the MDS XML files from an RPD file using this command:
biserverxmlgen -M -R repository_pathname [-P password] -D output_directory [-8] [-N] [-Q|-S]
So my question is basically is there a way to reverse this process, to use some command line tool (or Weblogic Scripting or some other mechanism) to create the RPD file from the MDS XML files? Are there options on the biserverxmlexec command that will do what I am asking?

Hey dmfairley,
Thanks for the question. You can absolutely export the project as .mp3, as outlined in this resource:
GarageBand Help: Export songs to disk
http://help.apple.com/garageband/mac/10.0/#gbnd7cbf5ed9
Export songs to disk
You can export a project to your computer as a stereo audio file.
Exported files can be reused in GarageBand to save processing resources by replacing or bypassing multiple regions, instruments, and effects. They can also be used with other music applications and devices, posted on the Internet (on a webpage, or in the iTunes Store, for example), added to an iTunes playlist, or uploaded to a mobile device such as iPhone or iPad.
1. Choose Share > Export Song to Disk.
2. To rename the exported file, select the name in the Save As field, then enter a new name.
3. Choose a location to save the exported file from the Where pop-up menu.
4. Select the format for the exported file (AAC, MP3, or AIFF).
5. Choose the quality setting for the exported file from the Quality pop-up menu.
6. Click Export.
Thanks,
Matt M.

Loading an xml file from an xml file

I'm trying to load an xml file from an xml file, but I'm
having problems. My first xml file is really simple - it only
contains one attribute with the name of another xml file in it
(eventually I will have multiple xml files in here and run a loop
on them...this is why I want to load an xml file from an xml file).
Currently, with the code below, I can get the main xml file
to load ("main.xml"), but I cannot get the secondary xml files to
load FROM the main.xml.
I want to then take childNode values from the secondary xml
file and use them within my .swf in text boxes and whatnot.
Any guidance? I think I'm going wrong on the line where I'm
saying "i.newxml.load(i.attributes.location);"
- How can I get this to work?

johnypeter:
I tried changing the code inside the loop to use just
"newxml" instead of "i.newxml", and I declared with "var newxml =
new XML();" - was this what you were thinking?
kglad:
The reason I tried to use the loadXML() function in the loop
was so that for each node in my "main.xml" it would load the new
xml file listed - this is a no-no? Do you have any ideas as to what
I could do?
For the for-loop, what should I change in it? I'm not great
with loops so I tried to modify some code from another loop I found
in another forum thread - not the right way to do it here?
Also, what should I trace? The value of the _root.address, or
i.attributes.location? I have created dynamic text boxes on my
stage to see if the correct value from the xml file loads (ie. the
name of the xml file within the xml file) and it does, but now I
don't know how to put that information into ANOTHER loadXML()
function and get the node information from it - does that make
sense???
Below are the examples of the xml files I am using. In the
first one, main.xml, I will have a list of multiple xml files, each
with the same nodes and elements as in the details.xml file
(different values, of course).
This is just to give you an example of what I'm trying to
accomplish - pulling ALL the addresses and phone numbers from
multiple xml files. I cannot manually collect this information, as
it is dynamic, and will be updated in each individual details.xml.
I was hoping to collect the information by simply adding to and
updating ONE xml file - main.xml.
Do you think this can be done? Am I going about it the wrong
way? I'm quite limited in AS knowledge, which is why I'm piecing
together code from other posts!

How to create a .DLL file from a .C file ?

Hi everybody
I'm looking for a method how to create a .DLL file from a .C file .That Dll file will be used to perform a board to measure voice quality accoding to the international standard named PESQ (perceptual evaluation of speech qualty) P.862.
Can anyone help to start dealing with Dlls and give some advices to avoid errors ?
thx

Hi sinaps,
You mention that you want to create a DLL from a .C file. Just to clarify, are you using C (.c file) or C++ (.cpp) to write your code?
Also, if you are using C++, are you using Visual Studio? (The reason I ask is because this forum is geared towards Measurement Studio, which is an add on to Microsoft Visual Studio).
That being said,
If you are using C: National Instruments provides an ANSI C Application Development Environment called LabWindows/CVI which makes building dlls a snap. It has templates for DLLs and you can build them either as stdcall or cdecl dlls.
Developer Zone Tutorial: Building a DLL with LabWindows/CVI 8.5 for use with LabVIEW 8.5
If you are using Visual C++: Look at the link that Al provided earlier.
MSDN: Walkthrough: Creating and Using a Dynamic Link Library
If you aren't using CVI or Visual Studio, then really the best bet is to do a google search for "Create C DLL" or post or a forum for the appropriate environment that you are using.
Thanks!

How to execute a .sql file from a batch file

Hi all
I've to take backup of a database weekly twice on every wednesday & Friday @ 5pm IST. I've written a hot backup script, which works every well.
now i want to automate the script. ie i want this script to run on wednesday & friday @ 5pm without any human interfearance ie with out actually any1 executing this script.
i created a batch file prod.bak with the following lines
@echo off
set oracle_sid=testdb
set oracle_home=d:\oracle\ora92
sqlplus /nolog
connect sys as sysdba/oracletest@testdb
this batch file when eexecuted connects me to sql prompt.
Now i want to execute my backup script bkp.sql automatically when it is connected to sql prompt.
(i tried with these lines in the above batch file...
call bkp.sql---it just opens the bkp.sql file in notepad & displays the script
start bkp.sql---same as call
connect / as sysdba/pwd@[email protected] --- does not work simply remains a the sql prompt.
At 17:00 /Every:w,f "d:\bkp.sql"---does not work simply remains at the sql promt.)
Can any1 let me know what should i write in the batch file that will execute the bkp.sql file automatically after it gets connected to sql prompt. M using oracle 9i.
I'll manage he time through windows utility of scheduling task.. Let me know how to execute the .sql file from a batch file.
Thanks
Tripti

Try
sqlplus "sys/oracletest as sysdba" @bpk.sql
Working locally, and having set the ORACLE_SID, you don't need to specify the SqlNet alias (@testdb).
Remember to put an exit at the end of the bpk.sql script.
