How to get line number in JAVA code?

Hi,
What method can I use to return the current line number of my coding?
Assuming I'm at line 10 and I want to do something like System.out.println("I am at line number " + ????);What method should I use to get "10"?
Please advise.
Thank you.

If you run Java in Dos prompt, a new line of result is displayed at bottom and the screen scroll. There is no line number in that way. Other language like C have something like that.
If you use Java Swing, you can display with x, y coordinate option but it is graphic mode.

How to get repository connection in java code

Hi!
I have a method in server-side java code. This is get a repository connection from Weblogic pool.
private DataSource getDataSource() throws WavesetException {
DataStore ds = Server.getServer().getRepository().getPrimaryDataStore();
DataSource dataSource = null;
if (ds instanceof RelationalDataStore) {
dataSource = ((RelationalDataStore)ds).getDataSource();
return dataSource;
I would like same this, but in the client side. After connection (SessionFactory.getSession...) I get a RemoteSession object.
How can I get a database (repository) connection?
Thanks,
Attila

com.waveset.util.Util.setWavesetHome("D:\\Tomcat 5.0\\webapps\\idm"); // if you are running this java code out side idm app
Session session = SessionFactory.getSession("configurator", new EncryptedData("configurator"));
LighthouseContext lh = session;
WSUser user = (WSUser) lh.getObject(Type.USER, "Testuser");
OR use below code
System.setProperty("waveset.home","D:\\Tomcat 5.0\\webapps\\idm");
// here we find the path
LighthouseContext lighthouseContext = new com.waveset.server.InternalSession();
WSUser user = (WSUser) lighthouseContext.getObject(Type.USER, "Testuser");

You have several ways under *nix
ifconfig -a | grep HWwill output something like
eth0 Lien encap:Ethernet HWaddr 00:11:FF:74:FF:B4combined with Runtime.getRuntime().exec("")and Process.getInputStream()you should be able to read it easilly.
Under Windows (and Linux of course) try jpcap (http://sourceforge.net/projects/jpcap)
You can also use jnative as a generic tool (http://sourceforge.net/projects/jnative)

How to get domain name in java code/custom security provider

Hi all,
I've developed a custom security provider and deployed it in WL_HOME/server/lib/mbeantypes folder. I also have multiple domain created and running in the same machine. now if a user logs in from a specific domain, say, t3://localhost:7005, how do I retrieve the domain name in my custom security provider?
I found the following code could do it, but this code needs to know the port number in advance
Hashtable env = new Hashtable();
env.put(Context.PROVIDER_URL,"t3://localhost:7101");
env.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL,"weblogic");
env.put(Context.SECURITY_CREDENTIALS,"weblogic1");
Context ctx = new InitialContext(env);
MBeanHome home = (MBeanHome)ctx.lookup(MBeanHome.ADMIN_JNDI_NAME);
String domainName = home.getDomainName();
System.out.println(domainName);
Any help is greatly appreciated...
Thanks,
Philip

How to get php content with java ??

i have made a php file what will display a number,
here's a example
<?php
if ($action == "answer"){
echo "18274926";
?>
no i want to get the number with java
so here's my java code
import java.io.*;
import java.net.*;
import java.util.Date;
class URLConnecties
    public static void main(String args[]) throws Exception
        int teken;
        URL url = new URL("http://www.gamer.mineurwar.nl/net/javachallenge.php?command=DaTe");
        URLConnection urlconnection = url.openConnection();
        System.out.println("Type inhoud: " +
            urlconnection.getContentType());
        System.out.println("Datum document: " +
            new Date(urlconnection.getDate()));
        System.out.println("Laatst gewijzigd: " +
            new Date(urlconnection.getLastModified()));
        System.out.println("Document vervalt: " +
            urlconnection.getExpiration());
        int lengteinhoud = urlconnection.getContentLength();
        System.out.println("Lengte inhoud: " + lengteinhoud);
        if (lengteinhoud > 0) {
            InputStream in = urlconnection.getInputStream();
            while ((teken = in.read()) != -1) {
                System.out.print((char) teken);
            in.close();
}if you change the url ro a .html file it displays the code correctly(source),
but when trying to get the content of a php file (the number)
it says that there is no content from the php file
yhe source of the original php file what's in the code can be found at
www.gamer.mineurwar.nl/net/javachallenge.txt

The 'content' is generated dynamically by a PHP script so the "content lenght" can't be known in advance by the server. For this reason connection.getContentLenght() returns -1; it doesn't mean that there is no content, only that it can't be known how much there will be.
To solve the issue, remove the if statement from around the while-loop:// if (lengteinhoud > 0) { DELETE THIS LINE
InputStream in = urlconnection.getInputStream();
while ((teken = in.read()) != -1) {
    System.out.print((char) teken);
// } and this too

How to get the number of files currently open?

hi,
does any one know how to get the number of files currently open in windows OS?
e.g. lets say .txt files...
any comment will be really appreciated.
thanks

Assuming that you don't want to actually do this from within Java code (which would obviously require native code), here's a utility that will give you a list of which file handles are opened by which processes (on Windows):

How to get paragraph number of selected text in ID CS4

Hi,
Can anybody help me how to get paragraph number of selected text in Indesign cs4.
Thanks,
Gopal

Ah, I see -- thanks. Turns out that there's no difference in speed between texts.itemByRange(), characters.itemByRange(),and insertionPoints.itemByRange(). In a document with 170 pages of text, and with the cursor in the last paragraph, the second and third lines, below (and your function), give exactly the same result:
t = app.selection[0];
t.parentStory.texts.itemByRange (t.parentStory.insertionPoints[0], t).paragraphs.length;
t.parentStory.characters.itemByRange (t.parentStory.characters[0], t).paragraphs.length;

How to get the number of elements in DB

Could you tell me how to get the number of elements in DB??
My code to get the number is below, but I think it is not efficient
DB->cursor(DB, NULL, &cursorp, 0);
while ((ret = cursorp->c_get(cursorp, &key, &data, DB_NEXT)) == 0)
count++;
--------------------------------------------------------------------------------------------------------------

Hi,
The most efficient way to get a count from the database is using the DB->stat API (http://docs.oracle.com/cd/E17076_02/html/api_reference/C/dbstat.html)
The code will be something like:
        DB *dbp;
        DB_BTREE_STAT *statp;
        int ret;
        /* Print out the number of records in the database. */
        if ((ret = dbp->stat(dbp, NULL, &statp, 0)) != 0) {
                dbp->err(dbp, ret, "DB->stat");
                goto err1;
        printf("%s: database contains %lu records\n",
            progname, (u_long)statp->bt_ndata);
        free(statp);The code comes from the example included in the distribution at examples/c/ex_btrec.c
If the database isn't a btree, you should update to the appropriate statistics structure and field.
It's worth noting that retrieving the count is never a "cheap" operation. The count is not stored in the database - since doing so introduced a single point of contention that creates a bottle neck.

How to get the number of messages consumed by a MDB ??

Hi all,
How to get the number of messages consumed by a MDB displayed in OEM in a Java Application ???
DMS ??? what use DMS ???
tanks

ok.
Well using DMS is one way to get at these sorts of stats in a programmatic manner.
There's a Java API you can use, or you could call out to the Spy servlet to query the DMS stats in either text or XML form.
I don't have an MDB published so I can't show you specifiically, but here's the sort of query you can use to extract the data.
http://localhost:8888/dms0/Spy?format=raw&table=oc4j_ejb_stateless_bean&recurse=children
Which produces a table of the TEXT form:
<DMSDUMP version='9.0.4' timestamp='1163456821185 (Tue Nov 14 08:57:01 CST 2006)' id='8888' name='OC4J'>
<statistics>
/oc4j [type=n/a]
/oc4j/default [type=oc4j_ear]
/oc4j/default/EJBs [type=oc4j_ejb]
/oc4j/default/EJBs/jmsrouter_ejb [type=oc4j_ejb_pkg]
/oc4j/default/EJBs/jmsrouter_ejb/AdminMgrBean [type=oc4j_ejb_stateless_bean]
pooled.count:     11     ops

pooled.value:     0     count
ready.count:     11     ops
ready.maxValue:     1     count
ready.minValue:     0     count
ready.value:     0     count
session-type.value:     Stateless
transaction-type.value:     Bean
/oc4j/default/EJBs/jmsrouter_ejb/EnqueuerBean [type=oc4j_ejb_stateless_bean]
pooled.count:     11     ops
pooled.maxValue:     0     count
pooled.minValue:     0     count
pooled.value:     0     count
ready.count:     11     ops
ready.maxValue:     0     count
ready.minValue:     0     count
ready.value:     0     count
session-type.value:     Stateless
transaction-type.value:     Bean
/oc4j/default/EJBs/jmsrouter_ejb/TimerHandlerBean [type=oc4j_ejb_stateless_bean]
pooled.count:     11     ops
pooled.maxValue:     0     count
pooled.minValue:     0     count
pooled.value:     0     count
ready.count:     11     ops
ready.maxValue:     0     count
ready.minValue:     0     count
ready.value:     0     count
session-type.value:     Stateless
transaction-type.value:     Bean
</statistics>
</DMSDUMP>
Or produces an XML document of the form:
http://localhost:8888/dms0/Spy?format=xml&table=oc4j_ejb_stateless_bean&recurse=children
You can use the Spy console to find the table that contains the details for MDB and then take it from there.
This is not what you specifically want to do, but it does provide a good overview of how DMS is used.
