Adding StringBuffer to an Array

In the following, I'm trying to add a StringBuffer to an Array.  It compiles fine, but at runtime it doesn't make it past where the buffer is being added.  Thanks in advance.

       


String[] strA = new String[1];
strA[1] = strBuf.toString();
	                			    out.println("doesn't make it here");
 
						       		HttpAccept sendMsg = new HttpAccept();
					       			sendMsg.doit(strA);
	           					    sendMsg.testEnvelope(strA);
	           					    out.println("MADE IT HERE")

You should check for exceptions that stop it reaching that line in your logs

e.g. a null StringBuffer will throw an NPE, preventing running to that line

You are also creating a String array of size 1 and trying to access index 1 when only index 0 is valid.

OK, so even if I do the following it throws the exception.  


                                              String[] strA = new String[0];

                                              strA[0] = strBuf.toString();

The code below is where I'm adding to the buffer.  Sorry for the noob question, Java 1.0 '97 was the last time I even looked at Java.  thanks again
   Enumeration e = request.getParameterNames();
    while (e.hasMoreElements()) {
      String name = (String) e.nextElement();
      String values[] = request.getParameterValues(name);
      if (values != null) {
        for (int i = 0; i < values.length; i++) {
         //out.println("NAME---" + name + "----NAME:" + " (" + i + "): " + values[i] + "THIS ONE");
         strBuf.append(name + values[i]);
 
        }
      }
}

>                                               String[] strA = new String[0];

that creates an array with 0 elements, should be (at least) 1

>                                               strA[0] = strBuf.toString();

first index is at 0.

I'm getting an arrayindexoutofbounds error .  Could the problem be related to the message I'm receiving?  The entire message is the StringBuffer that I'm trying to cram into the array so that I can wrap a SOAP envelope around it.

>                         String[] strA = new String[0];

as I mentioned above that should be:

                        String[] strA = new String[1];


>             String xmlString = args.toString();

and that should be:

xmlString = args[0];

though from what you've posted args could just be a string (instead of an array)

OK, sorry that I'm being dense.  I did change to 1 and the xmlString, but I'm still getting the indexoutofbounds error when it tries to add the buffer to one.

That resolved the issue thanks.  I'm not getting a different error regarding the webserver saying that the Options class is missing.  NoClassDefFoundError: Missing class: org.apache.axis.utils.Options.  Thanks again!

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
