How to get Websphere profile port related information ? using java and ANT

How to get Websphere profile port related information ?

There are actually two ways of getting the port related information used by a Websphere profile.

The first and foremost is to read through AboutThisProfile.txt from /logs .

Second one is to understand the serverindex.xml file inside the profile path . 

Sample Path / Location for this file is : C:\Program Files (x86)\IBM\WebSphere\AppServer\profiles\AppSrv01\config\cells\nc9118041010Node01Cell\nodes\nc9118041010Node01\serverindex.xml

Java Class which get this ports info is shown below ... using XML DOM parser code is written.

File operations in Java Read file, write into file, Append file

File operations in Java Read file, write into file, Append file

File operations involved majorly are reading it , writing into a file and appending it.
Reading from a File : 

try {
    BufferedReader in = new BufferedReader(new FileReader("infilename"));
    String str;
    while ((str = in.readLine()) != null) {
        process(str);
    }
    in.close();
} catch (IOException e) {
}


Writing into a File : 


try {
    BufferedWriter out = new BufferedWriter(new FileWriter("outfilename"));
    out.write("aString");
    out.close();
} catch (IOException e) {
}


Appending to a File : 

try {
    BufferedWriter out = new BufferedWriter(new FileWriter("filename", true));
    out.write("aString");
    out.close();
} catch (IOException e) {
}

wait for batch script to finish ran from java process

Running batch scripts through java and wait for it to complete which internally calls java processes.
The below example show how can we wait for the script to complete running.


public static void main(String[] args) throws InterruptedException,
            IOException {
        System.out.println("Starting ");
Runtime runtime = Runtime.getRuntime();
            String[] command = { "cmd.exe", "/C", "start /WAIT",
                    "C:\\Users\\IBM_ADMIN\\Desktop\\BVT31\\BVT31\\xFAST.bat",
                    "--cf", "IE_Configurations.properties", "--tc",
                    "scripts\\testCases" };
            Process p = runtime
                    .exec(command, null, new File(tipBVTScriptsPath));
            p.waitFor();
            System.out.println(p.exitValue());
}

String[] command = { "cmd.exe", "/C", "start /WAIT",....
Start /WAIT is the main thing to be understood here which will wait for the launched batch script in the separate window to get completed.
Once all the actions in the batch are completed the window remains open.
Hence the main important point here is to have "exit" statement as the last statement in the batch script which runs as process.

Invoking p(j)ython script through ant script to deploy and un-deploy WAR files in Websphere

How to invoke p(j)ython script through ANT scripts do deploy WAR files on to Webshere. ?  
The below is a simple ant script invoking python files which will deploy and un-deploy the given J2EE Apps in running Websphere server profile.
1. The ant script will invoke python files.
2. Ant script's target pathconvert will convert the property values containg back slashes in a file path to forward slashes.
3. Ant script target timestamp will print the time stamp along with message in the given log file. Takes care of new line character using 
 at the end of message ...
Ant Script to call jython scripts which will deploy and undeploy provided J2E WAR file.
Below is the Ant script.
