How I can set the Non-standard option of -Xmxn of jvm

Hi there,
Can any one tell me how I can set the Non-standard option of -Xmxn of jvm (setp by step).Iam using Sun's jvm(jdk1.2.2).Iam facing a error(java.lang .OutOfMemory).I want to set the maximum size of the memory allocation pool.Any help will be highly appreciated.
Thanks for ur valuable Time
Bikash

you can use the following sample options to specify memory size.
EX:java -Xms128mb -Xmx512mb myClassFile

Does j2se element in JNLP support non-standard options

I am trying to use options like -Xbootclasspath while starting the application to set search path for bootstrap classes and resources. Going by the documentation, it appears j2se supports options like initial-heap-size, max-heap-size but I could not find anything on Xbootclasspath.
Any pointers are welcome.
Thanks,
Raman.

No I'm sure you can't do this, it would open a huge security hole if you could. As webstart uses it's own classloaders it'd be pretty meaningless non the less.
If your trying to override the java or sun packages (eg for running LumberJack) your going to be bang out of luck, in any case it'd be prohibited by the Java 2 binary code license even if webstart allowed it.

Tuning JVM non-standard options

Hello,
I'm tring to deploy an executable jar file which builds an .xls file (using the JExcel API) w/ 5+ megs of data. Since there is so much data I need to tune the JVM to allocate more heap memory. When I run the program using the command line args shown below I have no trouble.
$ java -Xms16m -Xmx128m -jar dayReporter.jar
How do I add these -X args to an executable jar file so a user can simply double click?
Thanks!
Scott.

I am not quite sure if it'll work but you should try the java.lang.Runtime.exec mechanism. Therefore build a second app which just starts a new JVM-Process with the desired parameters.
Something like this:
Process jvm = Runtime.getRuntime().exec("/path/to/jvm/bin/java -X? -jar /path/tojar/jar");
jvm.waitFor();

What non-standard JVM options are common across vendors...

Hi all,
As the name explains, non-standard JVM options (java -X) are exactly that, non-standard. So from what I understand these can be different by vendor, by release, by platform, or any combination of the above.
What I'm trying to figure out is what's common between all the different implementations, if any. For example, are all of Sun's releases (for all platform, for all releases) have the same options? Or do they change by release, i.e. 1.3 to 1.4 to 1.5? Or do they change by platform (Win, Linux, etc).
Is there knowledge about this out there? So, far I haven't been able to find any info about commonality.
:-D

You could simplify the question: what are the standard non-standard options?

Is it possible to load a non-standard image using some Java API?

Hi,
My "problem" is:
1. I have an image called "mediterranean_sea.IMG" (non-standard image format)
2. I need to process it (histogram, palette, etc).
3. I'm wondering if it is possible to load this image an process it using some Java API.
4. I've tried to do this using JAI but I think that this API only works with TIFF, PNG, JPEG, etc.
Any idea?
Thanks in advance,
Roger

Non-standard fonts in JOptionPane

I have looked extensively through this forum, and no one has answered this specific question, even though it has been asked several different ways. Maybe someone has an answer now.
I am writing a client app using Java 1.4.2_02 that needs to display many languages. I have all of the European languages displaying correctly in JFileChooser and JOptionPane. I even have the Asian languages displaying correctly in JFileChooser. What I can't do is display the Asian languages (and probably any non-standard font) in JOptionPane correctly - all I see are boxes in place of the characters. Here is the relevant code of what I have tried so far:
        Locale.setDefault(Locale.JAPAN);
        int option = JOptionPane.YES_NO_OPTION;
        String [] buttonText = null;
        switch(option) {
            case JOptionPane.YES_NO_OPTION:
                buttonText = new String[2];
                buttonText[0] = UIManager.getString("OptionPane.yesButtonText");
                buttonText[1] = UIManager.getString("OptionPane.noButtonText");
                break;
            // other cases...
        JOptionPane jop = new JOptionPane("Do you wish to display Japanese fonts?",
                                          JOptionPane.ERROR_MESSAGE,
                                          option,
                                          null,
                                          buttonText);
        // Have tried many fonts - MS Gothic seems to be the one that should work, though.
        // BOLD seems to slightly work - I see a (Y) or a (N) after the strange characters.
        jop.setFont(new Font("MS Gothic", Font.BOLD, jop.getFont().getSize()));
        JDialog jopDialog = jop.createDialog(null, "Dialog Title");
        jopDialog.show();Even though most of the above code is from a post by one of the authors of "Java Internationalization", this doesn't work. Has anyone solved this problem?

To solve this problem, you have to tell the UIManager to set the font everywhere you need the new font. Unforunately, there is no one method call to do this. So here is the short version:
        localizedFont = new Font("MingLiU", Font.PLAIN, 12); // or whatever font you need
        UIManager.put("ToolTip.font", localizedFont);
        UIManager.put("OptionPane.font", localizedFont);
        UIManager.put("Button.font", localizedFont);
        // etc...    Another thread (I forget where) gave code to extract all of the properties of UIManager - find that thread to get all the properties.

Extracting non-standard xem content into XEM

Hi
Has anyone tried exracting non-standard xem content into BI.
Using the delivered xem data-dump tools I am able to indentify table/field names that I believe could be used for addtional reporting in BI.
However I am unable to create an additional connection from XEM to BI. I was told that cannot use UD Connect, partly because we have no experience in setting up such a connection.
I was told I cannot use DB connect as this is not the "recommended" access method for SAP systems. But it seems to me that this would be the most straightforward. Especially as I do not have access to java/netweaver programmers that could develop anyu other methods
both XEM and BI are running on Oracle, the XME database is very small and the table structure is not very complex.
So any comments/suggestions on how to process, and whether I should push the issue of considering DB connect as aviable option?
Regards
Philip

Finally!
I'd suggest making a small change to the documentation, along the lines of:
1. Login to the Oracle Collaboration Suite Control
2. Navigate to the Content section, typically called "Content".
3. From the Administration area at the bottom of the screen, select Formats.
4. You will be presented with a list of existing formats, searchable by Name. Select New Format to create a new format, or click on an existing format to edit its properties
I think that this would increase the usability of the documentation.

Using non-standard sshd port after 10.8 upgrade

After spending hours tracking down this solution as a result of losing my ssh settings after the upgrade to Mountain Lion, I thought it might be useful to post the steps taken to restore the configuration I used with Snow Leopard.
Changing the sshd default listening port
Disclaimer: This tutorial is specific to Mountain Lion (OS X 10.8). I was able to accomplish this using Snow Leopard (OS X 10.6) in fewer steps, but upgrading required this more involved solution.
Steps:
1.) You must first enable the root user account in order to change the relevant files. This can be done from the terminal, or by going to System Preferences --> Users & Groups. Once there, click on 'Login Options' at the bottom of the Current User list, and 'Join' where it says 'Network Account Server'.
This will bring up a smaller window. Click on 'Open Directory Utility' at the bottom. You will be prompted for your admin password. Now go to the 'Edit' tab at the top of the screen and toggle down to 'Enable Root User'. You will be prompted to enter your admin password twice.
2.) Log out of your regular user account. At the log in screen you will now see an additional entry for 'other'. Click on that and log in with the username 'root' and your admin password. If are inexperienced as a root-level user, be careful as you can cause problems to your system can be difficult to undo.
Once in your root account, the first step is to create a new 'service definition' in the etc/services file. Open the file with text editor of choice and scroll to the current entry for sshd listening port, which will look like this:
ssh    22/udp    # SSH Remote Login Protocol
ssh    22/tcp     # SSH Remote Login Protocol
Overwrite the '22' with the port number you would like sshd to listen on:
ssh    12345/udp   # SSH Remote Login Protocol
ssh    12345/tcp    # SSH Remote Login Protocol
*12345 being our hypothetical, non-standard port.
It is important to note that the new port number will not take by simply adding a new uncommented line to the file (I tried), unless of course you comment the original ssh entries. Easiest way is just to overwrite what is there already. Save changes.
3.) You now need to edit the ssh.plist file, which is located at /System/Library/LaunchDaemons/ssh.plist. A word to those familiar with Linux/BSD environments: changing the default port in the sshd_config file, which exists in OS X, does NOT change the listening port. Simply changing the default port, saving the config file, and restarting the server (the sensible way) won't work. The OS X sshd server (openssh) is configured to get launch instructions from the ssh.plist file, as opposed to sshd_config. If you are more interested in this aspect of OS X, read up on LaunchDaemons (e.g. launchd).
Before altering the ssh.plist file, you should save a backup copy in case of mistakes, or if you need to revert back to it in the future. Name your backup file something like original.ssh.plist, etc.
In the ssh.plist file, locate the SocksServiceName entry and change it from the default:
<key>SockServiceName</key>
<string>ssh</string>
To the following:
<key>SockServiceName</key>
<string>$alternate port number</string>
In our example from above this value would be 12345.
4.) Save your changes, and exit ssh.plist. You now need to move the backup file you created (original.ssh.plist) out of the System/Library/LaunchDaemons path.
The updated sshd port will not take until you have only one ssh.plist file in the LaunchDaemons directory - this has to do with how launchd is configured to load files which is outside the scope of the current discussion. (*If you've found a way around this, please share.)
5.) Restart the sshd server. Easiest way to accomplish this is going to System Preferences --> Sharing and clicking off 'Remote Login', then clicking back on it.
6.) Test the configuration by logging into the machine running the sshd server from another host using:
ssh username@ipaddress -p 12345
There are a few good tutorials out there that capture some of these steps, but many are dated and/or incomplete. If you are running a standard setup of OS X 10.8, this should work for you.
Of course, don't be fooled into thinking that changing the default listening port from the ubiquitously-probed 22 equates to actual security. At best, it will cut down on the number of dubious connection attempts and probing.

Hi all, above helped me change the sshd port number, thank you very much.
Just upgraded to OS X 10.9.3 on my macbook pro.
My findings were:
Step 1(become a root user or sudo)
Step 2 (/etc/services)
This may not be required unless you want ssh to work without the "-p XXXX" option to connect to other ssh hosts. I favor such as "ssh -p 2222 user@hostname" just to be sure I know what I am doing and also to leave ssh known port as its default "22".
Step 3 (/System/Library/LaunchDaemons/ssh.plist)
This is required if you want to change the sshd port number, I changed both "ssh" to "2222" in this file.
Step 4 (launchctl)
Below is a must as I understood:
launchctl unload /System/Library/LaunchDaemons/ssh.plist
launchctl load /System/Library/LaunchDaemons/ssh.plist
it should be already working with the new port number.
You can "ssh -p 2222 user@localhost" in the console terminal and see if its working.
Since I am no expert on MacOS X, and it is a macbook pro that I am using, I also rebooted the system and changes were reflected permanantly.
Thank you guys!

Oracle DB: How to parse XML where element names are non-standard ?

I'm in the unfortunate situation that I have illegal XML that I would like Oracle to parse. By 'illegal' in my case is that there are element names that start with an illegal character, such as a digit. Apart from this the XML is syntactically valid.
Here is an example of the XML I have stored as a column in the database:
<schedule>
    <1stweek>
    </1stweek>
    <2ndweek>
    </2ndweek>
</schedule>Right now I'm doing text search-and-replace on the XML text before I let Oracle parse it, for example replacing '<1stweek>' with '<x1stweek>' and so on. Needless to say this is very slow.
My question is if there is a way to tell the XML parser in the Oracle DB (I'm using version 10.2) to be a bit more forgiving ? ... so that it will accept element names that start with e.g. a digit ? I know that such an option exist in some XML parsers but what about Oracle's and if so how to set the option?
And before you ask I'll answer myself: No, I'm not the one who created the non-standard XML. It is from a third-party application which I cannot change myself and cannot get the vendor to change either.
Thank you.

if you cast your clob to an xmltype then you can search and extract values based on tags.
Heres an example where the table is a clob and value is cast and I'm looking for an existing attribute_name.
Check out the Oracle XML developers Guide
select u.*
FROM preload_xml
, XMLTable(
'/ApplicationProfile/ScriptFragment' PASSING xmltype(xml)
COLUMNS name varchar2(50 char) PATH '/ScriptFragment/@Name'
) u

Non-standard keys

Hi,
How can I respond to input from non-standard keys, like the forward and back keys on some keyboards? I've tried using the KeyEventDemo, but it doesn't record any events. Any ideas?
Thanks.

Try this:
KeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventDispatcher(
        new KeyEventDispatcher() {
            public boolean dispatchKeyEvent(KeyEvent e) {
                System.out.println(e.getKeyCode());
                return false;
});It will detect all keyevents and print the correpsonding keycode. If this code does not react when you press those arrow keys, then you cannot detect them using pure java.

Moving my non standard library

Dear friends,
I hope you'll be patient enough to bear with my question.
My music files are all stored on my iMac internal disk in a /Users/Bob/Music/rja directory with its own internal artist/album/tracks structure.
In my iTunes Preferences->Advanced, my music library is set to /Users/Bob/Music/rja2014 and NEITHER keep itunes organized nor copy files to iTunes media folder are checked.
Everything works beautifully, my metadata is now in good shape, artwork etc.
I am now in the need of moving this music to my external firewire storage and I am not sure how to go about it because of this non standard setup.
Any guidance would be receive with gratitude !
OS is Mavericks and iTunes is 11.1.5 (5)
Thank you in advance.
Robert

Because you manually manage music it won't be easy. If you let iTunes manage your media then you could use iTunes' consolidate feature to move your files to a different drive and have it keep track of them. If you were moving them to the same drive and manually manage then iTunes will keep track of them. Moving them to a different drive means all your links will break and thrre's no way to stop it really. "Moving" to a different drive is really copying and deleting.
Two options. One is to copy them to a different drive, then re-add them to a new iTunes library. Yes, yes, I hear you fuss, but for some who only have smart playlists and don't care about date added and ratings it works perfectly fine. The smart playlists repopulate everything automatically and as long as you use tagged media most of the metadata travels with the files.
Another is to move the files, then use a text editor to search and replace the location information for all the tracks in the .xml version of the library file. Use the .xml version to generate a new previous library with the changed information. You will still lose some information because the .xml does not 100% duplicate information stored in the .itl file and only iTunes can open that. If there is absolutely mission-critical information, using Applescripts you can try storing it in some non-standard location such as the comment field, then try to re-create things. E.g. Make a playlist with all your 5-star ratings files, copy the playlist over to the new library, then use that playlist as a basis for assigning 5 stars to all the items in playlist in the new library.

Help with custom page size support for non standard paper

Firstly, we appreciate any support you may be able to provide, we have already thrown considerable effort at this and it has been very time consuming and frustrating.
To support a number of business functions need to print to (non standard) continuous and mulitpart paper on a dot matrix printer. The (test) Mac is a 10.4.11 G4 laptop, the printer is an Oki Microline 520 (9 pin 80 column, IBM Proprinter, Microline or Epson FX personalities with a parallel interface) which has been networked via a HP JetDirext Ex Plus print server. That part appears to be operating correctly.
We have tried a number of drivers / printer personalities with varying levels of success:
ESP / EPSON 9-Pin Series CUPS v1.1 / Epson FX personality
ESP / OKIDATA 9-Pin Series CUPS v1.1 / Oki Microline personality
Ghostscript / epsonc / Epson Dot Matrix Foomatic PPD / Epson FX personality
Ghostscript / ibmpro / IBM ProPrinterII Foomatic PPD / IBM Proprinter personality
Ghostscript / okiibm / Oki Microline IBM compatible 9 pin Foomatic PPD / IBM Proprinter personality
There were no appropriate drivers in Gutenprint (5.2.3 version) The most successful is the okiibm / Oki Microline IBM compatible 9 pin settings, it can print A4 and honors the Printer Features Resolution settings in the print dialogue.
Q1: Should we see anything in the Printer Info / Installable Option, it is always blank ?
The issue is custom page sizes, we can manage / add Custom Pages Sizes via the Page Setup / Paper Size interface and they draw on the screen OK but they do not work at the printer (various issue at the printer such error messages, junk printing and wrong orientation):
Q2: Are we heading in the right direction or is there a better way to handle this ?
Q3: Would 10.5 solve all our problems, are the print drivers any better ?
Q4: Is this the correct way to specify custom page sizes, is this all we need to do ?
Q5: Is so how do we get the driver to respect the size, do we need another filter or something ?
Q6: Is it possible to add (by hand) custom page sizes to the ESP drivers or Foomatic PPD files so they they appear as a "standard" offering in the Page Setup / Paper Size interface ?
Sorry for the long / complicated post and thanks in advance for any advice / assistance.

Testing on 10.5.7, Tried both Oki 9-Pin Series 1.3 / Microline personality (no joy) and Epson 9-Pin Series 1.3 (this is a much better driver than 1.1) / Epson FX personality but not much joy with custom page sizes,
The Oki 9-pin Series 1.3 and the Epson 9-Pin Series 1.3 should produce the same results. The only difference in the PPDs is the printer model name.
After some testing, I find that the output is not the same despite the two PPDs being virtually identical. I did spot in the CUPS source code for the rastertoepson filter that there is some model name matching for Epson printers. Thus I can see where the output using the Oki 9-pin PPD could be different than when using the Epson 9-pin PPD.
but again once I imbedded the page size into the ppd some (but frustrating) luck. I can get it to respect the paper orientation and it prints well but I could not get the form length to work properly. At best over a print run of 7 labels it would creep up the label by about 0.1 inches / 2 mm.
Just for the fun of it, I made some additions to the Epson 9-pin 1.3 PPD. All I can say is that I could print a job to file. I have no way to know what it would look like on paper.
I did find that using a custom paper size did add some unwanted margins to the output bounding box. Putting the custom page size into the PPD seemed to get around that issue.
I added the following lines to the Epson 9-pin PPD 1.3--
<pre style="overflow: auto;font-size:small; font-family: Monaco, 'Courier New', Courier, monospace; color: #222; background: #ddd; padding: .3em .8em .3em .8em; font-size: 9px;">*PageSize Label1/Label1: "<</PageSize[288 107.8]/ImagingBBox null>>setpagedevice"
*PageRegion Label1/Label1: "<<PageSize[288 107.8]/ImagingBBox null>>setpagedevice"
*ImageableArea Label1/Label1: "0 0 288.00 107.80"
*PaperDimension Label1/Label1: "288.00 107.80"</pre>
This adds a paper size with the 4 inch (288pt) width and 1.5 inch (107.8pt) height. That represents the 1.4 inch label and the 0.1 inch gap between labels. I set 0pt margins except for the bottom where is set the 0.1 inch (7pt) gap as the bottom margin.
The full diff in context is--
<pre style="overflow: auto;font-size:small; font-family: Monaco, 'Courier New', Courier, monospace; color: #222; background: #ddd; padding: .3em .8em .3em .8em; font-size: 9px;">loki:~ matt$ diff -u /usr/share/cups/model/epson9.ppd ~/Desktop/epson9.ppd

How do I set non standard print size with Epson SX515 and iMac

I have an Epson SX515w printer and can't find any software on Epson that lets me set non standard print sizes. From my PC Laptop I can print all Avery sizes as well as any size I want. I want to print images to fit into small square frames.
