POString concatenation in java is not working on one system
text
Body
copied!<p>I believe that most of you would be thinking that this is the same question you have heard multiple times (and answered ) about string concatenation in Java. But trust me, it is different. In fact, so different that I am even hesitant in posting it here. But anyways, here it is. I have some piece of code which goes like:</p> <pre><code>public void handleSuccess(String result) { result = result.trim(); MessageBox.alert("Information","Result after trimming: '" + result + "'"); result = result.substring(result.indexOf('\n') + 1); MessageBox.alert("Information","Result after substring: '" + result + "'"); String returns = getReturns(); MessageBox.alert("Information","Returns: '" + returns + "'"); String action = getAction(); MessageBox.alert("Information","Action: '" + action + "'"); String finalResult = result + returns + action; MessageBox.alert("Information","Final result: '" + finalResult + "'"); } </code></pre> <p>Now the situation here is that, all of these : <strong>getReturns()</strong>, result and <strong>getAction()</strong> return non blank values, and in fact the string <strong>finalResult</strong> contains the concatenated value after the last line is executed. So, at Line 1, <strong>"result"</strong> contains <em>"12/03/2013|04-AERTY|"</em>. The value of result remains same at end of line 1,2. <strong>getReturns()</strong> returns value <em>12.4724</em>. So at end of line 3, <strong>finalResult</strong> contains <em>"12/03/2013|04-AERTY|12.4724"</em>. <strong>getAction()</strong> returns <em>"expt"</em>. So, at end of line 5, <strong>finalResult</strong> contains <em>"12/03/2013|04-AERTY|12.4724|expt"</em></p> <p>This is , when I debug or run the application in eclipse. As soon as build the same application on a UNIX system to generate a "war" file, and deploy the war on a tomcat server, the problem rears it's ugly head. When I run the application on the deployed war, the last line does not contain the concatenated value. So at the end of line 5, <strong>finalResult</strong> contains just <em>"12/03/2013|04-AERTY|12.4724"</em>. I expected it to contain <em>"12/03/2013|04-AERTY|12.4724|expt"</em> as it does while running in eclipse.</p> <p>I have tried <strong>stringbuffer</strong>, <strong>stringbuilder</strong> and the <strong>"+"</strong> operator as well, but nothing seems to work. I am not even getting an exception. Can somebody help me in fixing this or at least enlightening me in what I might be doing wrong here?</p> <p>Just to stress again, the code on eclipse(which is on a windows machine) and UNIX machine are exactly same. I have done a diff on them.</p> <p>Here is what I get after putting the message-boxes:</p> <ul> <li>Message-box 1: "Result after trimming: '12/03/2013|04-AERTY|'"</li> <li>Message-box 2: "Result after substring: '12/03/2013|04-AERTY|'"</li> <li>Message-box 3:"Returns: '12.4724'"</li> <li>Message-box 4:"Action: '|expt'"</li> <li>Message-box 5:"Final result: '12/03/2013|04-AERTY|12.4724|expt'"</li> </ul> <p>Message-box 5 output is the one I receive when I execute code using eclipse When running on deployed war, Message-box 1-4 have the same output as above, but Message-box 5 says: "Final result: '12/03/2013|04-AERTY|12.4724"</p>
