I assumed they meant "replacement [String]" but they meant "replacement [special set of characters]". Where the special set of characters is at least partially defined in the doc for the Matcher class and means you'll get unexpected behavior if the replacement String contains \ or $ and you did not realize the behavior is that of Matcher.replaceAll. The correct solution for me was techName = techName.replaceAll("[']", "\\\\'"); as I needed to change each ' to a \' for use as parameters to a javascript function. Maybe someone has written a RegEx class that uses methods and attributes rather than special characters to carry out its functions? Thanks for the feedback, TimJowers ============================================================================== TOPIC: JTextArea question http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/3b5070301a6779b ============================================================================== == 1 of 1 == Date: Wed, Dec 22 2004 1:23 am From: "Sherman Wang via JavaKB.com" I have the same problem: 1. My code has a non-editable JTextArea. My computer is XP professional with SP2. I compile my code using JDK 1.3.2. 2. When I run it using JRE 1.3.2, I can select text and copy it. 3. But If I run it using JRE 1.4.1_07, JRE 1.4.2_06 and JRE 1.5.0, the text is not selectable anymore. Because I use the same code and the same classes, I think there is something dependent on JRE. -- Message posted via http://www.javakb.com ============================================================================== TOPIC: long class name problem http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/54ffff98c385d2e8 ============================================================================== == 1 of 4 == Date: Wed, Dec 22 2004 3:02 am From: "T.

How much code is there in kilobytes? The reason I ask is that well meaning professionals[1] who write Java programs generally write absolutely terrible and hard to read code. I would be looking to get you to trim it down to the shortest compileable example[2] that displays the problem. And yes, you heard me right 'problem', singular. Solve one problem at a time.

It gives you all the advantages of a windows installer plus automatic updates. Plus, once a person has one JRE with WebStart installed, it will automatically update their JRE if you shift forward with your app too. ============================================================================== TOPIC: Which Compiler? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/eaff02cdae418719 ============================================================================== == 1 of 4 == Date: Wed, Dec 22 2004 3:44 am From: "Smitsky" > jikes from IBM research labs.

I was really fishing to find out if you had lots of arcane requirements for the editor. This tells me - no. >> Does this editor need to have an inbuilt debugger? > > Would be nice too. (shrugs) 'Would be nice' is not something I would consider a *requirement*, so I'll stick with my earlier advice - 'TextPad'. It is a lightweight editor with *none* of the above. It merely colors keywords (which I find preferable to autocomplete) and allows you to compile and run from within the editor. Others will almost certainly disagree with me. ;-) Now.. before I lose you attention, I am curious about one aspect of your original question.
