Java IO on top of a second file system layer

I have created a second file system on top of an existing file system, and I have java executing Java and Python(Jython) how would I get the IO they use to link to my file system and not the OS' file system?

Are you suggesting that you have created something like windows shared drives or windows condensed drives?
Because that is the only way you could create a IO system on "top" of an existing system. And if you have successfully done that then you do not need to do anything to java/python except 'point' them to the new location such as using a driver letter for a windows shared drive.
On the other hand if you have a bunch of java/python applications and you want to implement some other sort of file system then you would need to modify the virtual machines and the APIs of both of those.
And regardless all of the above WILL be a lot of work.
Now if you have some idea to implement a library that is useable (not replacement) for java/python apps then you
1. Create the library
2. Use the library
That solution requires a lot less work. Although certainly more than a trivial amount.

Java Card File System ...Please reply

Hi all ,
I am working on Java Card technology for last one year . Presently I am facing some problem regarding some file concept of java card .
I know that Java Card 2.1 does not support file system . But I want to simulate the file system in java card using applets . i.e . I want to write an application(applet) , which can simulate the EF , DF in smart card . Whenever APDU command is send to the file system applet , it should generate a Elementary file (EF) or dedicated file (DF) etc and store data to that file.
Can I do this type of thing using Java Card ? I am really in doubt .
If you have any idea on this , please let me know your view on this . If you know any open source code for this type of simulated Java card file system , please let me know .
I am desperately looking for a help .
regards
Dibyendu .
you can contact me to this email
[email protected]

dear duran ,
You have written that
"Follow the guidelines for the different supported filesystems on the JC"
But after Java Card version 2.0 , it does not support file system . I am using Java Card 2.1 .
Could please some sample code to my mail Id , so that I can take a look at it .
My mail id is : [email protected]
Please share the idea , as I am really need some help.
Regards ,
Dibyendu.

How to export repository to file system?

Hello,
within my bachelor thesis I am engaged in parsing ABAP Objects to calculate different code metrics. The analysis tool and many of the known parser-apis do require source-files at the file system layer.
As SAP stores everything in a DB, I wonder if there is a way to export the repository to the file system. And if this is not possible, is there another practicable way to access the source code?
Another point is: Does anyone know a source for a complete grammar (like ebnf or so) for ABAP Objects? that could make my life quite a lot easier...

Thanks for your advice! I've written this report:
START-OF-SELECTION.
DATA: source TYPE REF TO cl_oo_source,
source_tab TYPE seop_source_string,
classname TYPE seoclskey VALUE 'CL_OO_SOURCE'.
CREATE OBJECT source EXPORTING clskey = classname.
* Copy source->SOURCE table because gui_download( ) needs a changeable
* argument and source->source is read-only.
source_tab = source->source.
cl_gui_frontend_services=>gui_download( EXPORTING filename =
'c:\source.ao' CHANGING data_tab = source_tab ).
But that approach has some serious drawbacks:
I have to save each class one by one (is there a way to automate that? P.e. find all classes in one package?)
I can not access the code of reports and such because cl_oo_source requires a classname.
Is there another way or an extension to this one, to solve those problems?
Thanks,

Placing an image on top of a flash file

Is there a way to keep a image on top of a flash file? When I
place it on top then publish the flash file jumps in front of the
pic when it plays.
What I am trying to do is place a border around the window. I
can't just shrink the flash file down because this great program
causes errors with the flash content.

There is no way to keep an image on top of a Flash file.
Having said that, we do a couple things to get around that:
1: add the border to the flash file-- when we're creating
swfs for Breeze in Captivate or Flash itself, we add the highlight
or border there
2: Add the border to a file that rests behind the flash file
and make the flash file fit
It sounds as if you've tried the second, but with no success.
I 've never had a problem resizing swfs that I've imported into ppt
through Breeze Presenter. I sthat the issue you're having?

Have trouble double clicking on a second file to open

There are really two problems here:
1) If I double click on a file, it opens in Illustrator, but it does not open with my default workspace settings. If I open the file from the file menu, my preferred workspace opens.
and
2) If I have one file open, I cannot double click on a second file and have that file open in Illustrator. I just get the little spinning circle and then it stops. I can still open a second file from the file/open menu option.
We are using CS6 and running windows 7.

Brett,
The issues which you have mentioned points towards having some permissions issue on the system.
My suggestion would be to make sure that the user account which are using is Administrator.
Also, make sure you have full permission on the location mentioned in the document below:
http://helpx.adobe.com/illustrator/kb/preference-file-location-illustrator.html
Here are the steps to modify ownership and permissions of folders and files:
1.       Right-click the file or folder, click Properties, and then click the Security tab.
2.       Click Advanced, and then click the Owner tab.
3.       Click Edit, and then do one of the following:
·         To change the owner to a user or group that is not listed, click Other users and groups and, inEnter the object name to select (examples), type the name of the user or group, and then click OK.
·         To change the owner to a user or group that is listed, in the Change owner to box, click the new owner.
4.       If you want to take ownership of the contents of the folder, select the Replace owner on sub containers and objects check box.
5.       Click OK, and then click Yes when you receive the following message:
          You do not have permission to read the contents of directory folder name. Do you want to replace the directory permissions with permissions granting you Full Control?
          All permissions will be replaced if you click Yes.
Note folder name is the name of the folder that you want to take ownership of.
6.       Click OK, and then reapply the permissions and security settings that you want for the folder and its contents.
Additional considerations
   ·         An administrator can take ownership of any file on the computer.
   ·         Assigning ownership of a file or a folder might require you to elevate your permissions using
Let me know if you need more help on this.

I have photoshop CC. I cannot open two files such as Tiffs and view them side by side. When I open the second file it overrides the first. Do I need to do something with preferences?

I have photoshop CC. I cannot open two files such as Tiffs and view them side by side. When I open the second file it overrides the first. Do I need to do something with preferences?

What happens when you try to use the clone stamp tool?
It should work with the images side by side.
You can setup photoshop cc to be like photoshop cs2 was on your other mac, by going to Photoshop>Preferences>Interface and unchecking
Open Documents as Tabs and Enable Floating Document Window Docking
And also going to Window and unchecking Application Frame

Than how can i get java class by using it's class file?

Hi
After compilation of a java program, it creates a class file.
After getting class file suppose class file has been deleted.
Than how can i get java class by using it's class file?
Thanks in advance.

get a decompiler and run your class file through it--I'll assume you want the source code back and that you are not trying to recover a missing class file by attempting to use the class file that is missing--if it's missing, then I've not a clue on how to get it back by using what is already missing.
BTW: many of your compilers have source control--if it does, just restore your missing file.

How to setup word docs, converted to PDF on local drive with links to a second file at a page

how to setup word docs, converted to PDF on local drive with links to a second file at a page
Need to setup a set of word documents, converted to PDF that has links from one file to a second file at a given page.
I would like to setup a set of pdf documents, on the hard disk of a PC or Mac, that can be open with acrobat pro running on the same computer and have the link jump to, and open in a new window, in acrobat pro, to a given page of a second document in the set.
Is there a way to setup a link in word and the conversion to pdf that will result in a link that is equivalent to the acrobat link type you get when you add a link of the type Go to a page in another document?
Tools-Advanced Editing-Link tool, make a box
Check: Go to page view, Next (Create go to view dialog opens)
Open second document and go to page
Click “Create go to view dialog” to set up link
Result is a link, when view by link properties, with an action of
Go to a page in another document
File: C:\My Documents\second file.pdf
Page: 43
Zoom level: Custom
I got close but did not solve the problem:
I have a version that uses links to a website, using #page=43 at the end of the hyperlink.
That works but will only open to the page if is through the web browser, opening the acrobat reader plugin.
I need to open from a folder on the local harddisk (with relative links), in acrobat pro to the given page of the pdf, on a PC or a Mac.
I could bookmark each page “pagenumberxxx” and jump to the bookmark/page if that would get around some problem
Current Systems in use to create documents with links and view them:
Windows XP SP3
Word 2003 SP3
Acrobat 9 pro version 9.4.4
Or just to view them:
Mac OS 10 Lion version 10.7.4
Acrobat 9 pro version 9.5.1
(note I have limited understanding of Mac’s)
John

No. There seems to be no automated way to do it. You can of course go into the PDF and manually add links after you have converted to PDF, but that is what we want to avoid having to do. We want it to be automatic from the Word doc.

ECC6 EHP2 (ABAP+Java) system copy using file system copy

Hello Experts,
I have a question around system copy method for a dual stack ECC6 EHP2 system.
We are planning to take full file system backup of this entire ECC6 EHP2 dual stack system and throw it on a completely new hardware with new host name but same SID. We are also planning to do a host renaming in instance profiles and re-building the control files in target system after we finish the file system restore.
Is this method supported in SAP ? Or we strictly have to use SAPinst to do export and import method. In any case our source and target platform is not going to chance as per our scenario.
Any suggestions will be greatly appreciated.
Thanks,
Harshal

> Thanks for the quick response. Is their any document that says it is not supported ? Because of no proper document that says no to do it, client want's to try it out.
For the ABAP part this is certainly feasible.
The Java part has not only issues with the secure store but also with SID and hostname. The old values are stored in many places in the database and in, depending on the applications installed, many .properties files in the filesystem. So it would be not enough to somehow regenerate the secure store but also change hostname and SID in different places that are not really all documented.
What you are basically looking for is
Note 757692 - Changing the hostname for J2EE Engine 6.40/7.0 installation
with the significant sentence
This note should be applied only when the hostname of a machine
where the j2ee engine was already installed has changed.
It does not replace the SAP official system copy procedure and
MUST NOT be used for copying of an instance to another host and/or with different SID.

Invoice Lines spill over to top of the second page

Hi,
I have a program that prints invoice and its lines. Looks like if there are too many lines that do not fit one page, it spills the lines on top of the second page rather than the space provided for lines.
How can I correct this so that the line appears in the lines area of the invoice report rather than writes on top of the header on the second page.
Thanks for help.

Photoshop elements 6 crashes when opening second file

Hi all,
At work we've migrated our pc's from windows xp sp2 to windows xp with sp3 and the latest security patches. Since that time people that open a second file (jpeg) in photoshop elements 6, results in a crash of the program. Unfortunately the windows eventviewer records no error whatsoever.
Has anyone experienced this behavior before?

Is this issue resolved in Photoshop Elements 8?
I don't know -- haven't heard any reports of it, but that doesn't mean anything. Neither does the lack of tech articles about the issue in the knowledge base (Adobe doesn't keep it well-updated). The issue used to happen with me before I changed printers. The best thing to do is to download the free trial of PSE 8 and try it.

Java Stored Proc - ORA-03113: end-of-file on communication channel

Help with error please.
Running java stored procedure and getting
end-of-file error. This error occurs after successful connection established.
Simple function returns a java.util.String that is a coded version of the DATE parameter. Procedure does not use a connection object.
Error message and description list below.
ERROR at line 1:
ORA-03113: end-of-file on communication channel
Cause: An unexpected end-of-file was processed on the communication channel. The problem could not be handled by the Net8, two task, software. This message could occur if the shadow two-task process associated with a Net8 connect has terminated abnormally, or if there is a physical failure of the interprocess communication vehicle, that is, the network or server machine went down.
Action: If this message occurs during a connection attempt, check the setup files for the appropriate Net8 driver and confirm Net8 software is correctly installed on the server. If the message occurs after a connection is well established, and the error is not due to a physical failure, check if a trace file was generated on the server at failure time. Existence of a trace file may suggest an Oracle internal error that requires the assistance of customer support.
I am currently looking into the trace file as suggested.
Thanks

Java.util.zip.ZipException: Too many open files on Linux

Hi,
We have web application running on Caucho's resin server on jdk 1.5.0_11 and Red hat Linux. We are noticing that java process is running out of file handles within 24-30 hours. We have file limit of 5000 which it consumes in 24 hours throwing 'java.util.zip.ZipException: Too many open files'.
I have made sure all sorts of file handles are closed from application point of view. Here is the snapshot of lsof (list of file handles) from java process. The following list keeps growing until it runs out of limit. Do you have tips/suggestions on how to mitigate this problem (considering we dont want to increase ulimit for this process)? Also, can you make out any thing more from the description of file handles like, are they unclosed POP3 connections or URL connection to external sites?

Finally we resolved this issue. It was oracle driver which had some compatibility issue, we upgraded our Oracle client driver to newer version, and this fixed the problem. Base line, there was nothing wrong with application code, code was doing good resource clean up, but oracle driver was leaking handles per every connection.
