How to launch Jar file in Mac Os using java code??

can anyone tell me how can i launch another jar file in my apllication using java code.

define "launch".
- You want to run a new java program in a separate process? (see Runtime.exec())
- You want to run a method in a specific class in the jar? (add jar to application classpath and then simply instantiate the class and call the method)

How can we get requester's user id using java code

Hi,
How can we get requester's user id using java code?
eg: If i had logged in as xelsysadm and request a resource for user uid101 on the userid field it should display uid101 and not xelsysadm.
also,
I have a resoure "A" which on revoking should also revoke resources B and C. How can it be done. Resource A, B, and C are 3 different resource objects.
==Thanks,
doki

Ok, so there is a way, but it's not available during submission. You can use the findRequests api. From the result set, get the "Requests.Consolidated Data Value" value. In this information, you will get an xml formatted data. It provides the list of users on the request on the left side after submission. After the request is completed, this value is available. Upon completion, you could get the request information, get this value, and parse the information for user ids.
In the same adapter, use the following API:
formIntf.setObjectFormData(objInstanceKey, formHash)
The formHash is a hashtable containing the field name on your object form, and the values you wish to populate it with. You could create a textarea box on your object form and populate the userids for who the request is for.
However, this makes absolutely 0 sense. When you get a request, the list of userids are listed right there on the request.

How to send sms to mobile from tomcatserver using java code?

Hi,
Could you please let me know that,
How to send sms to mobile from tomcatserver using java code? Please provide the code snippet.
Thanks in advance.

Yes, but something needs to send that message. You can't just take an arbitrary computer and send an SMS, it does not have the hardware to do that.
So either you have a mobile through which you do that or more likely - you use some sort of online service to do it. Whatever choice you make will determine what code you will have to write to get it done. Nobody is going to deliver the code to you, that's your job. It is also your job to figure out what service you are going to use.

i any have clear idea on this... pls throw the ways how to convert........

Hi Rajesh,
JAR file in itself in not deployable.
So v need to envelop this jar file into an EAR file and then v deploy this EAR file on SDM.
Creating Jar
Inside NWDS --> Windows --> Open perspective --> J2EE Development --> right click on ur proj --> Build EJB Archive
Converting .EAR file to .SDA

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 dynamically configure JPA setting at runtime using java code?

Hi,
I am new to EJB 3.0 and JPA. I am trying to help my company to deploy the use of JPA in EJB3.0. Currently, i am trying out with OpenJPA in IBM Webshpere Application Server 7.0. We have four different WAS servers running for testing, system integration testing, user testing and production respectively, and in each region, the configurations for data source, JDBC username and password, schema, etc are different. So i think i would need to configure the JPA setting during runtime using Java code that determines which is the environment. And apparently i am stuck with the limited knowledge i have.
1) I understand that i could override the JDBC in the persistence xml by creating entity manager using entity manager factory. But is it possible that i do similar thing by using inejction of persistence context on entity manager to obtain a container managed entity manager?
2) Alternatively, it is possible to create multiple persistence unit in the XML and inject different PU to the entity manager, am i right? But how to inject dynamically since @PersistenceContext(unitName="xxx") only accepts constant declaration.
3) Is it possible that the JDBC username and password are read from properties file?
Thanks for your help in advance!

Hi
Thanks for the reply.
Are you saying that i have to configure the data source authentication to the backend DB2 using the JAAS-J2C? Correct me if i am mistaken. I guess i am unable to do so as the application server setup only contains one data source, and the server hosted a number of applications. Every applications has their own JDBC username and password supply to the data source (the ID supplied at the DB2 side will decide which resource can access) and thus, i have to supply the username and password at runtime. Talked to the server guy and seems that it is not feasible to have seperate datasource for each applications as considered to the volume of applications hosted inside the server.
Any suggestion?

JAR file isn't found using java -cp

Hi all!
This works:
META-INF/MANIFEST.MF:
Manifest-Version: 1.0
Class-Path: TSA.JAR
Main-Class: p.Start
-which makes my jar file executable (as expected)
I need to be able to make changes in the classpath though, so I can change TSA.JAR to e.g. TSA2.JAR, TSA3.JAR etc. This should be obtainable by using the java -cp option, but this doesn't seem to work:
First, I delete the Class-Path line in the MANIFEST.MF file. Then I invoke java -cp TSA.JAR -jar MyProg.Startjava sais it cannot find some file contained in the TSA.JAR file.
What's happening? Why aren't the resources in the TSA.JAR file located? Does java expect to find Class-Path in the MANIFEST.MF file, and since it's not located it expects no classpath is set (even though specified by the -cp option) ??

Ok, I found this:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4356783
-which states that when using the -jar option, all other classpaths are ignored. Just as all the authors of the numerous replies, I agree that this behaviour is too restrictive. The thread is worth browsing if you got 5 minutes to spare.
I solved my problem by not using the -jar option, but just to specify all involving resources by use of -cp option:
java -cp TSA.JAR;MyJar.JAR MyProg.Start

How to read/write text file to db2 by using java code

Hai
I created the table to insert a clob data as follows
db2 => create table ctest(datas clob(65536))
DB20000I The SQL command completed successfully.
db2 => describe table ctest
Column Type Type
name schema name Length Scale Nulls
DATAS SYSIBM CLOB 65536 0 Yes
1 record(s) selected.
I tried the following java code to insert a clob data.
public static synchronized Connection getConnection() throws Exception {
Connection m_connectionDatabase = null;
try {
Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");
// Get the connection to the database.
m_connectionDatabase = DriverManager.getConnection(
"jdbc b2 ps","","");
}catch (Exception e) {
throw new Exception("Failed to connect to the database. ", e);
return m_connectionDatabase;
public static void main(String a[]) {
File file = new File("d:\\a.txt");
InputStream fis = new FileInputStream(file);
Connection con = getConnection();
PreparedStatement pstmt = con.prepareStatement("insert into ctest values(?)");
//try 1
pstmt.setAsciiStream(1,fis,(int)file.length());
// try 2
pstmt.setCharacterStream(1,fis,(int)(file.length()));
// try 3
pstmt.setBinaryStream(1,fis,(int)(file.length()));
// try 4
byte[] b = new byte[fis.available()];
fis.read(b);
pstmt.setBytes(1, b);
// try 5
byte[] b = new byte[fis.available()];
fis.read(b);
pstmt.setString(1, new String(b));
pstmt.executeUpdate();
pstmt.close();
fis.close();
Result:
If the file size is less than 32kb, it inserted successfully.
but if more than 32kb, it throws follwing exception
COM.ibm.db2.jdbc.DB2Exception: [IBM][CLI Driver][DB2/NT] SQL0352N An unsupported SQLTYPE was encountered in position "1" of the input list (SQLDA). SQLSTATE=56084

CAN ANYONE SEND ME THE CODE FOR PRINTING .tif FILE?YOU CANNOT PRINT A TIFF DIRECTLY FROM JAVA SINCE IT WILL NOT LOAD A TIFF!!! YOU HAVE TO USE JAVA ADVANCED IMAGINING TO GET THE FILE TO LOAD AND THERE ARE EXAMPLES ON HOW TO DO THAT IN THE JAI LIBRAIRY. ONCE YOU CAN GET THE TIFF TO LOAD YOU CAN USE WHAT EVER YOU HAVE NOW TO PRINT IT, THERE ISN'T ANY MAGIC, YOU JUST HAVE TO HAVE THE IMAGE LOADED FIRST.
