Problem connecting to Lotus Directory from Java.

I am very new to LDAP and I have a problem. I am writing java code to connect to lotus directory and I am getting an exception.
Following is the code :

constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);
System.out.println("Constarints....." + constraints.getCountLimit());
NamingEnumeration results = ctx.search("o=philps.com","sn=keith",constraints);
while(results != null && results.hasMore()){
SearchResult sr = (SearchResult) results.next();
String dn = sr.getName();
System.out.println("Distinguished Name is " + dn);
Attributes attr = sr.getAttributes();
for(NamingEnumeration ne = attr.getAll();ne.hasMoreElements();){

for(Enumeration vals = localAttr.getAll();vals.hasMoreElements();){
System.out.println("\t" + vals.nextElement());
System.out.println("\n");
catch(Exception ex){
ex.printStackTrace();
System.exit(1);
Following is the exception description:

Russ,
Chances are good that you have installed the software on a DHCP machine. Oracle9iAS can only be installed on fixed IP address machines.

When connecting to OID directory from ODSM, orcladmin account is locked

Hi everyone,
I met a problem when I try to connect to OID directory from ODSM. [LDAP: error code 53 - Password Policy Error :9001: cn=orcladmin : Your account is locked. Contact your OID administrator.]
I tried to use command to unlock the super user
oidpasswd connect=OIDDB unlock_su_acct=true
OID DB user password:****
OID super user account unlocked successfully.
But I still cannot connect to OID directory with cn=orcladmin. The LDAP error 9001: cn=orcladmin : Your account is locked still exists. Could anyone tell me how to resolve the problem? Thanks!

We are facing the same problem in a production system with clustering and load balancing. The problem appears if there is no activity on bpel tasks for more than 30 minutes. We found that there exists a timeout parameter in the load balancer defined at 30 mins.
According to documentation, there exist two configuration parameters that are relevant to the problem:
1. in jazn.xml
<property name="jndi.ctx_pool.timeout" value="1600000" />
2. in is_config.xml
<connection url="ldap://ldaphost:port" binddn="***" password="***" encrypted="true">
<pool initsize="1" maxsize="25" prefsize="10" timeout="60"/>
</connection>
None of them solved the problem!
Does anyone have a solution?

Problem calling two perl modules from java in seperate threads(JVM CRASHES)

Dear Friends,
I have one severe problem regarding calling perl modules from java
I had to call two perl modules simultaneously (i.e.) from two threads,,, but jvm crashes when one of the perl calls is exiting earlier
I am unable to spot out why ....
For calling perl from java ...., We are first calling C code from java using JNI and then Perl code from C
All works fine if we call only one perl call at a time.... If we call them in a synchronized manner the JVM is not crashing .... But we don't want blocking..
The following is the code snippet

How to connect iseries green screen from java program

how to connect iseries green screen from java program to get the data in the DB files ,here the DB is DB2/400

Just some Friday fun. Use the telnet program that comes with Windows and supports VT escape sequences.

Problem connecting to lotus notes server.

Hey Everyone
I am using:
Windows XP, service pack 2
PC suite 6.85.14.1
Bluetooth connection
Phone Nokia E65
I am trying to connect my laptop to the office lotus notes server. But it seems PC sync can’t locate my id file or the notes server. The fields under sync setup are simply empty.
My Notes client didn’t have any problems connecting to the server.
There are about 10 other people in the office all using the same setup (Nokia E65 and a the same type laptop) without problems.
I have tried the solution in this topic but it didn’t help: /discussions/board/message?board.id=pcsuite&message.id=24092&query.id=149864#M24092.
Any idea what the problem might be?
Thx in advance
\Andreas

open regedit
go to HKEY_CURRENT_USER\Software\Nokia\PCSync\Settings
open => NotesIni
instead of for exemple => C:\Application_Data\notes\
type the entire path => C:\Application_Data\notes\Notes.ini
it should work

Connecting sap crm database from java | platform used NWDS

I need to get some values from one of the SAP CRM 2007 database table and display it in one jsp file. I am working on a e commerce webshop in NWDS. I am new to NWDS. Can you give some sample code showing how to make connection to crm database and to do a select query on a table.

I have only worked with CRM 3.0/4.0 but I have worked some with other WDP applications.
So you want to access some data in a table in the CRM backend (R/3)?
To do that from Java you need to call a BAPI in the CRM system. The BAPI does the acctuall lookup in the table and returns the value to the Java side. To do that in a WDP environment you need to set up Java Connectors (jCo) in your Java server. In some cases you can use a "normal" BAPI call, that is the way CRM ISA 3.0 and 4.0 works. See: http://help.sap.com/saphelp_crm30/helpdata/en/b6/97f8378f975450e10000009b38f8cf/frameset.htm
and here:
https://websmp108.sap-ag.de/~form/sapnet?_FRAME=CONTAINER&_OBJECT=011000358700000633682005E
Here is how to access ABAP functions from WDP: http://help.sap.com/saphelp_webas630/helpdata/en/c3/76b45d9688e04abe1a1070410ddc1e/frameset.htm

Problems with running quote server from Java Tutorial

Hello
The problem is this: I try to run QuoteServer from java tutorial (Trail: Deployment
Lesson: Applets, A Simple Network Client Applet) and server compiles but when I try to run it following message shows up:
QuoteServer listening on port: 32769
Exception in thread "QuoteServer" java.lang.NullPointerException
at java.net.DatagramPacket.setData(DatagramPacket.java:244)
at java.net.DatagramPacket.<init>(DatagramPacket.java:62)
at java.net.DatagramPacket.<init>(DatagramPacket.java:78)
at QuoteServerThread.run(QuoteServerThread.java:38)
And then server stops. What's going on?.
Cheers

Line 38 of QuoteServer.java is: packet = new DatagramPacket(buf, 256);
And that's where the problem is because in line 31 is written byte[] buf = null;
And what I get when I run QuoteServer.java with gcj version of java (gives more clues) is:
java QuoteServer
QuoteServer listening on port: 32785
Exception in thread "QuoteServer" java.lang.NullPointerException: Null buffer
at java.net.DatagramPacket.setData(byte[], int, int) (/usr/lib/libgcj.so.6.0.0)
at java.net.DatagramPacket.DatagramPacket(byte[], int, int) (/usr/lib/libgcj.so.6.0.0)

at QuoteServerThread.run() (Unknown Source)
at .GC_start_routine (/usr/lib/libgcj.so.6.0.0)
at .__clone (/lib/libc-2.3.5.so)
So the problem is with this null buffer. What enter in line 31 instead of null?.
What values can byte[] reach except null?. I tried to find byte[] in java API but there is only Byte variable. I get the same output with java 5.0 compiler (but less clues).

Need to access/connect Remote Unix server from Java

Please any one give me a direct solution for connecting a remote Unix server through telnet connection from java application. Thanks in advance..

If I run the below program codes, in the console it is asking to enter username and password in manual but I need to give it automatically.
The highlighted "root" is entered by the user manually using keyboard.
Expected:
I mean the username, password and some action is set to be automatic, so that it should not ask the user to enter the input from keyboard.

Problems connecting to iTunes store from PC?

After upgrading to the new iTunes version, I am having problems connecting to the iTunes store from any of my laptops. no problem with the Macbook pro.
I deleted the programs and re-installed them, and no change. Any suggestions?

Close your iTunes,
Go to command Prompt -
(Win 7/Vista) - START>PROGRAMS>ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".
(Win XP SP2 n above) - START>PROGRAMS>ACCESSORIES>Command Prompt
In the "Command Prompt" screen, type in
netsh winsock reset
Hit "ENTER" key
Restart your computer.
If you do get a prompt after restart windows to remap LSP, just click NO.
Now launch your iTunes and see if it is working now.
If you are still having these type of problems after trying the winsock reset, refer to this article to identify which software in your system is inserting LSP:

Problem while running dos command from java program

Dear friends,
I need to terminate a running jar file from my java program which is running in the windows os.
For that i have an dos command to find process id of java program and kill by using tskill command.
Command to find process id is,
wmic /output:ProcessList.txt process where "name='java.exe'" get commandline,processid
This command gives the ProcessList.txt file and it contains the processid. I have to read this file to find the processid.
when i execute this command in dos prompt, it gives the processid in the ProcessList.txt file. But when i execute the same command in java program it keeps running mode only.
Code to run this command is,
public class KillProcess {
     public static void main(String args[]) {
          KillProcess kProcess = new KillProcess();
          kProcess.getRunningProcess();
          kProcess = new KillProcess();
          kProcess.readProcessFile();
     public void getRunningProcess() {
          String cmd = "wmic /output:ProcessList.txt process where \"name='java.exe'\" get commandline,processid";
          try {
               Runtime run = Runtime.getRuntime();
               Process process = run.exec(cmd);
               int i = process.waitFor();
               String s = null;

}     when i remove the process.waitFor(), then while reading the ProcessList.txt file, it says "No such file".
if i give process.waitFor(), then it's in running mode and program is not completed.
Colud anyone please tell me how to handle this situation?
or Is there anyother way to kill the one running process in windows from java program?
Thanks in advance,

Hi masijade,
The modified code is,

}when i execute the above code, i got output as,

If i execute the same command in dos prompt,
CommandLine
ProcessId
java -classpath ./../lib/StartApp.jar;./../lib; com.abc.middle.startapp.StartAPP 2468
If i modify the command as,
cmd.exe /C wmic process where "name='java.exe'" get commandline,processid > 123.txt
and keeps in running mode only.
If i open the file when program in running mode, no contents in that file.
If i terminte the program and if i open the file, then i find the processid in that file.
Can you help me to solve this issue?

Specify a exe running from certain directory from java program

Hi there,
I had a java program, which will spawn some child process to run vb COM;
what I wanted to do: have a child process start the COM from a specific diretory?
IS there any way to do it from Java, like shell programming?
Thanks

I do all my portable shell stuff now in ant.. http://jakarta.apache.org/ant/
it is an XML driven java script for doing builds.. but it can be used for shell scripting.
They are also some java scripting languages like jPython but i am not very familiar with them.
u can also get Cygwin and write unix shell scripts. www.cygwin.com
hope this helps

Accessing ACTIVE DIRECTORY FROM JAVA CODE

I am trying to access the Active DIrectory user through a java code.
Kindly let me know the steps apart from creating the user in ADS to be followed so that the following java code may work.
presently it is giving the following error.

This is what I have for my LDAP connection.

 public Control[] connCtls = null;

public LDAPAuth(String ldapurl) {

 } catch (AuthenticationException e) {
 System.out.println("Authentication exception " + e);
 } catch (NamingException e) {
 System.out.println("Naming exception " + e);
 public Attributes fetch(String username) throws NamingException {
 DirContext ctx = new InitialDirContext(env);
 Attributes attributes = ctx.getAttributes(username);
 try {
 System.out.println("fetching: " + username);
 Object obj = ctx.lookup("cn=" + username
 + baseName);
 System.out.println("cn=" + username + baseName + "is bound to: " + obj);
 //attributes = obj.getAttributes("");
 for (NamingEnumeration<?> ae = attributes.getAll(); ae
 .hasMoreElements();) {
 Attribute attr = (Attribute) ae.next();
 String attrId = attr.getID();
 for (NamingEnumeration<?> vals = attr.getAll(); vals.hasMore();) {
 String value = vals.next().toString();
 System.out.println(attrId + ": " + value);
 } catch (NamingException e) {
 System.out.println(" Problem looking up " + username + baseName + ". " + e);
 return attributes;
Now, I'm sure it has something to do with how I'm passing in the username and the groups. But I want to have ANY user log in, not just this test. I may be a little confused on how this works, but if anyone could explain to me why what I am trying to do doesn't work, I would greatly appreciate it.
Thanks in advance,
Tetsuya.

Problem connecting to SQL Server from JDeveloper 10g using jdbc third party

I am using Oracle 10g Jdeveloper and I tried to setup a database
connection to SQL Server using various Drivers for JDBC as Merlin, jtds, inet.tds, etc.
(I had no problem to set up a connection to an Oracle Database using the
Oracle JDBC driver).
When I am testing the connection throughout the wizard, I do receive
this error message: "Unable to find driver:
com.microsoft.jdbc.sqlserver.SQLServerDriver".
I m not understanding from last 3 days where to place the corresponding JAR files so thaI may not get the Error.
When I hit n trialed at various directories of the JDeveloper as </rootDir/jdbc/lib>
</rootDir/lib>
</root/jdev/my Work/Application1/Project1/public_html>
</root/jdev/my Work/Application1/Project1/public_html/web-inf/>
when I tested the connection I do received:
"Unable to find driver:
xxx.xxx.xxx.xxxxxxx Unable to find driver:
Obviously it can't locate the Micrososft JDBC driver but I can't
figure out why.
I tried all kind of things without any success. Is somebody can help
me and took me beyond this.
I m trying to build DataSource connection from JavaBeans.
Please make me out of this cave. I m not finding any of the way to do this.
The last code I tried is
try {
Class.forName("com.inet.pool.PoolDriver");
com.inet.tds.TdsDataSource tds = new com.inet.tds.TdsDataSource();
tds.setServerName( "local" );
tds.setDatabaseName( "bluff" );
tds.setUser( dbUserName );
tds.setPassword( dbPassword );
DataSource ds = tds;
Connection con = ds.getConnection(dbUserName,dbPassword);
Statement stmt;
ResultSet rs = null;
Thanks,

you are confusing me at least as your error is discussing the microsoft driver yet you are configuring the inet datasource.
I do not use JDeveloper, but you need to make sure that whatever is servicing your web app/JavaBean has access to the driver. Not sure why you are not doing a JNDI look up of the resoure, but because you are not you can stick the driver jar in the lib directory within the WAR bundle. I would suggest that you add the driver to the lib/ext or the lib directory which is loaded at boot time for your web container and then use JNDI to look up your DataSource to reduce your coding maintenance headaches.
