Accessing a Jar file within my jar...

Hi,
I've got a JDBC Jar file that I wish to include in my Jar package, but I'm unsure how to do this...
I'm using ant to compile my code & package it up into the Jar, & I can get it to compile fine, and package everything up fine (including the JDBC jar), but when I go to run the app I get an error
(No suitable driver).
My app works fine without being Jar'ed up.
I'm guessing that I need to set the classpath to reference the JDBC jar file in my jar... but I'm unsure how to do this.
Any help would be greatly appreciated.

package what you thirdpart jar file and your jar file to one jar file..
it will run ok.
maybe the below tool can help you.
a tool named JavaJar(written by java) can compress and decompress jar,war, ear and.zip...
may download from http://www.qwerks.com/download/4114/JavaJar.zip
the tool is very verygood tool.
but the homepage(www.pivotonic.com) of JavaJar cannot be accessed.
it is funny.
good lucky.

Access a data file within a jar package

hello, everyone
I got a problem in locating a data file packaged in jar file.
For example, in foo.jar there is a data file with the directory path "d1/d2/data.log". In the command line, I want to access that data file by making it as an input to the Main class which will load data.log at runtime. However, it reported exception of "no such file or directory". In the command line, I input:
java -classpath foo.jar d1.d2.Main d1/d2/data.log
any suggestion?
Thanks
Chinyi

I don't understand what you're trying to do by including d1/d2/data.log in the commandline? It appears to be extraneous and invalid.
Assuming:
that the class you want to execute is Main.class in foo.jar, and that its path in the jar is di/d2, and
that Main uses d1.d2.data.log when it access this file, it should work.

Viewing PDF files within your browser

Ever since I updated to a newer version of the reader (about a week ago), every time I try to access a pdf file within my browser (Firefox), I get the message "The version of Acrobar Reader currently running cannot view PDF files within your browser..." Does anyone have a fix?

I installed Adobe Acrobat Reader 9.3 last night and started having the same exact problem. This morning I went to START and using the "Start Search" feature box typed in "Adobe" because I wanted to see if I still had any older Adobe Acrobat Reader files on my computer that were competing with 9.3. As soon as I typed "Adobe" and clicked on the magnifying glass (or just hit "enter") I received a message that Windows was initializing Adobe Acrobat 9.3. After it finished initializing everything worked perfectly. The problem appears to be that Windows is not initializing the download automatically upon restart. Maybe my fix was a fluke, but it is working fine now.

File within jar

I created a jar file for my application using eclipse
within my project i have some file my application uses as images
i have a issue with the path to write to access those files
currently although all those files are already in the jar i have to create a folder duplicate those files and copy the jar in that folder to be able to use my resources.
to be more specific assuming i have
Package1
Package1.class1
Package2
Package2.image
what will be the path to write in class1 to open the image file?
I print out the directory while the program is running and it is the directory in which the jar file is
so i use this path
./myproject.jar/package2/images
in class1 code but it can not find the file(no such file error)
My question is what is the path to write in class1 to open a file located in package 2
Thanks

The relative path to an image file or other resource file is always in relation to the current class file that is executing.
So your class in Package1 cannot have access to an image in Package2.
It is just impossible.
The only way to do this is to move your image files at a location relative to the class that requires the files within Package1.

Java Access Helper Jar file problem

Excellent question. I don't see any client-jar in your EAR file structure. So I am assuming you are writing a separate client application which will talk to the ejbs deployed as part of this EAR. You need to do the following:
Write another EAR file with the following structure:
ear:
META-INF/application.xml
util.jar
client.jar
client.jar should have a META-INF/MANIFEST.MF and that should contain Class-Path:util.jar and value for Main-Class attribute.
Now deploy this new ear to your application server and execute it using Application Client Container that comes with your app server.
If you don't want to write another EAR file, then bundle th client.jar in your original EAR file.
Points to note are:
you have to repackage util.jar again inside this ear file.
For portability reason, you should use Class-Path manifest entry in client.jar. Refer to http://java.sun.com/j2ee/verified/packaging.html and J2EE platform spec section #8.2.
Hope this helps,
Sahoo

Accessing a jar file

Hi all
Is it possible to access a txt file that is in a jar file???
That is , I've created a jar file that contains a txt file, now in my script, I need to access this txt file, is this possible?
Thanks , Dave

Yes.
See http://java.sun.com/docs/books/tutorial/jar/index.html for the specific details and sample code.

Can't able to access the Jar files which is kept inside the folder.

Hi,
I am using the eclipse IDE, my project folder contains the folders src, bin, .metadata, .settings
if i place the jar file in the same location of the above mentioned folder means i can able to use the Jar file in eclipse(in my project).
But i create one folder in the same location in the name of Jar or anything and all jar files are placed inside the folder,then i can't able to access the jar file in eclipse(in my project).
How i can solve this problem?

..How i can solve this problem?Put Eclipse aside for the moment and learn how the SDK tools work at the level of the command line, then you will be much better placed to figure how to do it in the IDE.

Actually, I want to write an application which runs both online and offline. So I have chosen Applet and All the files Which I need are zipped and is Archived through <Applet ARCHIVE="example.zip">.
Now I want to access those XML files which are inside example.zip from my Applet.
How can I do that?
I think I will get security Exception.
How to get rid of this security Exception.
Kindly Answer soon.......
It's very urgent.
Thanking you,

Did you already try signing a jarfile? If no ->>
You can call a class inside a jar-file within the applet.
if this class should be able to acces files the jarfile
first has to be signed. to do this, you must generate a key.
the complete work:
1. write your applet
2. write a html-page with following code:
<APPLET code="guestbook.class" archive="guestbook.jar" width=600 height=400></APPLET>
3. make a zip-file with the guestbook.class, guestbook.form, guestbook$1.class, guestbook$... and rename it to guestbook.jar
4. in the console type:
keytool -genkey -alias YOURNAME
5. sign the key to your jarfile with:
jarsigner guestbook.jar YOURNAME
6. try the applet. a warning should appear which you have to answer
with YES then it should work
my trouble is that i cant acces files anyway because right now i don�t
alreadv have the clue to get the right (absolute?) path for the file. means i get an ioexception because the applet cant find the file :-((
does anyone know how to solve this problem then? my code is:
FileReader Stream = new FileReader("/members/Ui97u8g4f6b89mj90kh5gbr4ecf6KXC4/guestbook.txt");

Accessing JAXR registry from within web service

Hi I'm having trouble accessing the registry from within a web service running in the tomcat server.
The service should register with the registry at startup, but in the logs from the tomcat server I can see that a JAXRException is thrown:
javax.xml.registry.JAXRException: Unable to create ConnectionFactory: Provider com.sun.xml.registry.common.ConnectionFactoryImpl not found
at javax.xml.registry.ConnectionFactory.newInstance(Unknown Source)
If I run the program from outside the tomcat server as a standalone program, it registers perfectly.
I believe the problem is that it is missing one or more jars.
I have tried to put the jaxr-jars under shared/libs but that hasn't solved the problem.
Has anyone an idea of what I'm doing wrong?
Help is greatly appreciated!
/ Bo

Hi swatdba
I know that the build file states alle the packages that I need, and as I said, if I run my program like the regular JAXR examples, it works fine.
The thing is, the JAXR examples are not web services on their own. They are merely Java programs that access the registry.
In my case I am building a web service that should run in the tomcat server. When it initialises, it should register with the register, and also be able to search for other web services.
I thought this would be possible per default, ie. the jars that the web service needs should already be available in the tomcat server, but it doesn't work. I have tried to put the jars that I've found in the build script in the folder C:\jwsdp-1.3\shared\lib, which according to the tomcat manual should be used to put jars that you want to share between your web services.

Class not found in web-inf/classes folder of war file within ear file

Hi all,
          I am using Weblogic 8.1 sp4. I have a war file within an ear file. I am trying to deploy the war file with a few classes within its web-inf/classes folder, however when the classes are in that folder I consistently get a class not found exception when trying to instantiate them. If I package the classes in a jar file and then put that jar file within the web-inf/lib folder of the war, the classes are also not found.
          If I put these two classes in the app-inf/classes folder of the ear file, everything works as expected and the classes are found.
          Any ideas of why this is happening. This seems to be a very simple thing that should work, but appears to not be working at all.
          thanks in advance for any suggestions or ideas.

How can i locate the properties files within a ejb container?

when i develop servlet+javabean structure application,in order to imploement decoupling,i
would like to write the config information in the properties files(key-value pair),in
servlet,i use "getResourceAsStream(String relativePath)" method to retrieve the
configuration information from the properties files(i even write the SQL clause
in the files),it alwsys works well.
now,i want to implement such function within the ejb container,that is to read
a properties file from session bean,but i don't know how can i locate the file
within the ejb container by using relative path,i wonder if there is the same
method within ejb container as "getResourceAsStream(.......)" method within servlet
container?
thanks for any helps!
the code snippet is appreciated!

In general, you should look at using environment entries (variables) in the
deployment descriptors (both the war and EJB jar rather than properties
files for configuring J2EE applications. The reasons for this are many:
1. This is the official way to do it according to the spec. Properties
files are the J2SE way of doing things
2. As you note, that it's not obvious how you would (legally) read a
properties file inside an EJB.
3. It's consistent between the web and EJB part of your code
4. the weblogic console and tools have good capabilities to edit these
fields.

Question re Accessing catalogues and files from an external hard drive in Elements 6.

Having just acquired an ehd, I have successfully carried out a trial back up of an Elements 6 2000 picture catalogue from an XP based PC, using the Elements 6 full back-up process. This process is intended to be used eventually to transfer this and other catalogues onto a new Windows 8 PC installed with Elements 11.
However, in the interim I would also like to be able to access the picture files and the catalogue data on the ehd from a Vista based laptop which also has Elements 6 installed. Can you please advise how to do this without carrying out a full restore process that would load all of the files onto my laptop's hard drive.
In transferring the picture files to the ehd I also seem to have lost the original file structure that was on my PC, as folders have been renamed numerically and are all held individually in the main folder of the ehd. Whilst this doesn't matter too much whilst the files remain on the ehd, provided the catalogue still knows where to find them, has the original file structure been permanently lost, or can I recreate it when I eventually restore the files and catalogue on the new Windows 8 PC?
I'm anxious to get this process right as I have a much larger catalogue to similarly back-up and transfer, once I have acquired the new PC, and was hoping to be able to similarly access this catalogue by my laptop from the ehd as there is insufficent hard disk space on my laptop to hold all the 20,000 files involved.
Please help
Gardener 179

Thanks for your help re my original questions.
Reassured regarding not having lost the file structure of my pictures, and bearing in mind the relatively small catalogue I had backed up, I thought that rather than restoring by leaving the picture files on the EHD, I would after all restore to the laptop hard drive, as a trial run before dealing with my main catalogue.
The restore was successful but raised a number of further issues that I would appreciate your advice on:-
1) The original catalogue name was not used in the restoration process. The restored catalogue on the laptop has simply been named "Pictures". Is this normal and if I now rename the restored catalogue will this create problems with any subsequent supplementary backups of the catalogue?
2) In restoring the catalogue I heeded the Adobe Help and specified the Vista folder C:\Users\Maurice\Pictures as the location for the picture files rather than simply restoring the original XP folder structure. However, since I also wanted to retain the lower level folder structure of my XP files (which are basically date files) I then specified to "Retain the Original Folder Structure". This has resulted in the full XP folder structure being created within \Pictures on the laptop.
Is it possible to avoid this situation occurring, or will I have to remove the unwanted XP sub-folder structure from the laptop and reconnect the thumbnails in the Photoshop catalogue to the new file locations? Also if I have to move files in this way will I once again have problems with any subsequent restorations of the same catalogue?
I have also a couple of supplementary questions re the initial backup to the EHD which I have now looked at more closely:-
1) The original XP catalogue has 1853 picture files, (and this is identical to that subsequently restored on the laptop), yet in backing up the catalogue to the EHD it seems that in excess of 2200 picture files have been created. Why is this?
2) As previously advised the pictures are held on the EHD numbered sequentially as "b000001" etc, and due to my selecting the EHD top level root folder as the destination for the back up are held in F:\. Should I have created a new folder, say "Backup 1" on the EHD, and then specified this as the destination folder, as I am concerned that on backing up further catalogues the existing picture files will get overwritten and the Photoshop Backup and Catalogue files confused with previous backups? If so can I move the existing back up files to a new folder now without causing any problems?
Finally could you confirm what would have happened to the folder structure on the EHD had I carried out the Restore process by locating the picture files on the EHD but retaining their original file structure. Would the picture files have been copied into their original file structure for use by the restored catalogue and the duplicate backup files left unaltered, or would the backup picture files have been replaced by the restored file structure? Also would the "catalogue file" be transferred to the Laptop C:\ drive in this process or would this also stay on the EHD and be accessed from there by Photoshop?
Sorry for all the questions but I really want to fully understand what is going on before risking doing anything to move my main catalogue.
Regards
