Hi,

I am a Java developer and thinking to enter into PEGA BPM world. Is this the right time to enter into it or it is too late ? Other technology suggestions are welcome.

Thanks.

That is dynamically generated by parsing through XML file. XML file is generated on Unix server and i am parsing it by putting on Windows.

What makes it to work with StringTokenizer and not with replaceAll ?
9 years ago
It is line separator only. As the sample string i suggested is getting converted to single line when i use StringTokenizer class. Using StringTokenizer class it has identified the line separator but not with replaceAll method. Below is the code i have used while using StringTokenizer -

StringTokenizer st = new StringTokenizer(str, System.getProperty("line.separator"));
StringBuffer buf = new StringBuffer();
while(st.hasMoreTokens()) {
String token = st.nextToken().trim();
buf.append(token);
}

After this buf contains all in single line. But i am not interested in using StringTokenizer and unable to figure out why it is not working with replaceAll method.

Thanks.

Hi,

I have a String variable containing values across multiple lines like -

String str = "Hello World
Welcome To Java
Enjoy coding in Java";

I want to convert it to a single line so that it looks like - "Hello World Welcome To Java Enjoy coding in Java".

I attempted following implementation. But it is not working -

str = str.replaceAll(System.getProperty("line.separator"), " ");

After replaceAll execution, str variable is still containing the original value. Please suggest.

THanks.

No, I will sending the request to SMTP server. before that i need to form the complete email body and also provide details about the files to be attached.

I want to know how to handle the files located on remote machine.

Hi,

I am implementing an email server using EJB, JMS.It should also attach a file passed by client remotely. My doubt is how can i attach the file which lies on some remote system ?

Do i need to first FTP the file on server and then use it for attachment or is there any other way to do so ?
