How to set the horisontal offset for a node relative its parent in JTree?

When using large icons for nodes in a JTree the whole tree looks very compact. I found a method setRowHeight(int height) to set the row height that got med some space between the rows. But I couldn't find a simular method to increase the offset between a child node and its parent.
Any suggestions?

You can control the offset through the BasicTreeUI, as discussed in this thread:

SRM 4.0- How to set the default values for product type (01) only for SC

The radio button Service should not be visible.
Also for search help (e.g. search for internal products) where a search should only be possible for product type 01 (goods). The system should not display the product type and internally always search for goods only.
How to set the default values for product type (01) only for SC
We needs to use Search help BBPH_PRODUCT which having parameter PRODUCT_TYPE
Here we can set defalut value 01 but it is not correct one since same search help is using several places.
We need to limit the search help results only for SC.
Kindly help out me ASAP.

The easiest way to set defautl values is to edit the batch class.
Goto the characteiristic and go to update values.
In here you probably have something like 0 - 100 as a spec range.
On the next line enter the default value within this range. At the end of the line, click in the box in the column labelled "D". This indicates the defautl value for the characteristic.
If you need to you can do this in the material classification view as well.
Just to be clear, these values will only show up in the batch record. You can not have defautl values in resutls recording screens.

"I would like to know how to set the default view for the columns. Somewhere I read it could be done in by music icon under Library. Can't find it. Thanks

"I would like to know how to set the default view for the columns that are shown in iTunes. Every time I open it, I have to either go to the options, or right-click to get the pop-up options, and delete "rating" and add "composer." I'd really like to just do it once and be done with it." Somewhere I read you could do this by clicking on the Music icon under LIBRARY then arramge the columns. Trouble is, I can't find a Musi Folder or icon in my user library.
Any help would be appreiated. OSX 10.9.2 iTunes version 11.1.5 Thanks!!! CW!

From the iTunes menu bar try View>Show View Options. Make sure what you want to see is checked and what you don't is unchecked. You can do this (may need to do this) for any playlists, your main Library, etc.
Good luck

How to set the AS2 fileName for outbound Functional Ack 997 auto generated by Oracle B2B

Hi Friends,
How to set the AS2 fileName for outbound Functional Ack 997 auto generated by Oracle B2B.
External Trading Partner is sending the EDI 856 via AS2 URL to our Oracle B2B Server.
In the inbound 856 agreement, we have checked the option of Funtional Ack and also Functiona Ack handled by B2B is yes.
We have the outbound agreement which is sending that Functional ack 997 (auto generated by oracle b2b) and we have specified the Outbound AS2 channel of the Partner.
997 doc is being sent to external partner using AS2 channel, but the filename is generating as '40101'.
Please can you let me know how to set the AS2 fileName for outbound Functional Ack 997 auto generated by Oracle B2B.
Appreciate your valuable answers!!
Thanks,
Amirineni

Amirineni,
AFAIK, there is no option to set the file name when the 997 is generated automatically by B2B.
Alternatively, if this is a must requirement, you can generate the FA from backend and send to B2B with MSG_TYPE =9. In this case, you can set the header with filename (How to set the actionname property in B2B 11g)

Sun ONE Studio 4 aka Forte: How to set the output path for classes ?

Help !
Beginner's question:
Sun ONE Studio 4 aka Forte:
How to set the output path for classes ?
As default, the class files are created in the same directory as the
sources.
In opposite, both JBuilder and Together support that there is a tree
with the sources and another tree with the classes.
The first answer I got was "not possible with Forte, but just if you write your own "ANT Build script" !
a) Please point me to a ready-to-use ANT script for this purpose, if such is available
b) Is using ANT instead of the MAKE as comfortable ? Besides the separation of sourcecode and classes, I would like to keep everything else to be the same, i.e. I don�t want to edit the ANT file if I enlarge the project by directories or files.
Tia
Sincerely
Rolf

You can set S1S's options to place newly created .class files in a specific location.
Identify the compiler that is being used - Open the S1S's Tools/Options window, expand Editing and select Java Sources. Note the Default Compiler value. (If it's one if the Ant options, you use Ant to specify this option, not S1S.)
Open the S1S's Tools/Options window, expand Building/Compiler Types and select the appropriate compiler.
The Properties tab of the compiler has the property Target, which sets the filesystem where the compiler output is directed. If you choose <not set>, the .class files are written to their source directory.
When you set the Target, your change affects all classes that use this compiler.
Very few options can't be set in S1S; the challenge is finding out where they're set!

How to set the stack size for alchemy application?

Anybody know how to set the stack size for alchemy application?
If you know, please tell me how to adjust the stack size for alchemy application?

Hi,
The stack size is set as public const gstackSize in the alchemy generated code. You can see this if you build with ACHACKS_TMPS set. The default is one megabyte.
One way to change the stack size is to use llvm-dis to disassemble avm2-libc/lib/avm2-libc.l.bc, generating avm2-libc.l.ll, modify the constant, and then use llvm-as to recompile your modified library and overwrite the old one. These utilities should be in your path if alchemy is set up.

Right-click the WINDOWS desktop, choose New->Microsoft Data Link. That will bring up a dialog that allows you to configure and test your database connection. You might connect to the Access database via ODBC or directly via Jet Engine. The Jet Enginge saves you the trouble of creating an ODBC connection on your PC. After you leave the dialog, the "data link" will show up on your desktop as text file. Open it and copy-paste the connection string to your VI.
This webpage is an excellent resource for connection strings: http://www.able-consulting.com/ADO_Conn.htm
If your application requires users to change the database connection at runtime, you can also include the dialog via ActiveX (MSDASC.IDataSourceLocator).

How to set the default NetworkInterface for the default socket factory?

Hi,
I would like to know how to set the default network interface used by the JVM. I saw that you can specify the network interface when creating a socket. But my problem is that I dont want to change every socket creation in the application and even worse some partner's libraries wich I dont have access to code also create sockets. So is there a way to specify to the JVM wich interface to use by default? I didn't saw any System.properties to set this and my googling fishing didn't return anything usefull.
Thanks

By default it will use whichever one the routing tables tell it will give the shortest path to the destination. For globabl changes, adjust your routing tables. You can't do this from Java, you have to use whatever OS tools are to hand.

How to set the working directory for reports in linux

Hi All,
Can you anyone help me to set the working directory for oracle application server 10g reports? I am using RHEL4 and AS10g. Actually i want to run my reports from my define
working directory. How can I do this?
Thanks in advance
Arif

Hi,
your rep_srv.conf should look like something like
+<?xml version = '1.0' encoding = 'ISO-8859-1'?>+
+<!DOCTYPE server PUBLIC "-//Oracle Corp.//DTD Reports Server Configuration //EN" "file:D:\oracle\FRHome_1/reports/dtd/rwserverconf.dtd">+

++

+...+
some more definitions

+<pluginParam name="xmlpds" type="file">xmlpds.conf</pluginParam>+

*+</environment>+*
*+<environment id="APP2">+*
*+<envVariable name="REPORTS_PATH" value="/application2/reports"/>+*
+</environment>+
+</server>+
The environment ids you can choose yourself and you have to put them in there yourself too (here I put two environments for two different applications "1" and "2").
If you call a report from Forms, then you have to code something like
ADD_PARAMETER(p_list,'ENVID',TEXT_PARAMETER,'APP1');
Details depend on how you call your reports, my example is for using a parameter list and calling a report out of application1
Hope that helps.

How to set the debug port for Eclipse for OracleAS 10g Enterprise

Hello All,
I am using OracleAS 10g Enterprise, and using dcmctl to startup the server.
But i do not know how to set the debug port in the startup script for debugging with Eclipse.
I have tried to add the following options to the dcmctl.bat, but still failed:
-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=4000
i.e in the dcmctl.bat script:
set jvmargs=-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=4000
set ex=%ohome%\jdk\bin\java -Djava.net.preferIPv4Stack=true %jvmargs%
Do anyone know how to configure the debug port setting?
Thank you for your great help!.

Hi, have you double checked that your oc4j is started with Sun's JVM or any other JVM that recognizes the kind of remote debug option as above? You can find the JVM used by oc4j in the ORACL_HOME/opmn/conf/opmn.xml.
To double check that your oc4j is started in debug mode, you can test with another remote debugger. Say, with the jdb in sun's jdk jdb -connect com.sun.jdi.SocketAttach:hostname=yourHost,port=4000 (Personally, I also use Jdeveloper or Jswat to double check.) If you can connect with jdb, then you have to check your Eclipse. Can its remote debugger connect to any java application at all?

How to set the fetch size for a ResultSet object?

Connection con = getConnection();
Statement stmt = con.createConnection();
ResultSet res = stmt.executeQuery("select * from table");
//res.setFetchSize(?);
while (res.next)
res.get....
}I do not know the number of rows .
How can I set the fetch size for the ResultSet object?
I try
res.last();
res.setFetchSize(res.getRow()/2);
res.beforeFirst();
while (res.next)
res.get....
}but it's so slow if there are 6000 rows.
How can I set the fetch size for the ResultSet object more effectible?
And what is the best number to set the fetch size?

The fetch size defaults to a standard number. It is unlikely that it will be any faster if you set it unless you only plan to read a small number of rows.
i.e. if you are going to read all the rows, you need to read all the rows no matter what.
Unless the system has set the fetch size to 1 changing it will not be faster.
Depending on the row length, reading in 6000 rows is going to take a long time. You could try using a cpu profiler to improve performance.
Do you really need to read everything in every row?

[SOLVED] How to set the packager name for an AUR package?

Hi,
I'm maintaining an AUR package (fspcc), but I don't know how to set the name of the "packager" for that package.
E.g. when you request info about some package
$ pacman -Qi somepkg
there is a line
Packager: Unknown Packager
that specifies the packager.
How do I set this "Packager" info so that any user installing my package will see what I want?
Last edited by lisztinf (2014-04-13 13:39:43)

Thanks for the answer.
I guess that when I run
$ makepkg
in my local build directory, then "mkpkg" will build a package with the "Packager" info set accordingly to my local makepkg.conf.
However, I would like another user - with his own makepkg.conf - to see what I want when installing the package. How can I achieve this?
If I install an official package - say pacman itself - through ABS, I see the "Packager" field properly set for that official package. But certainly this info doesn't come from my local makepkg.conf. I would like the same behaviour for my package. Is it possible?
