my environment is :
<pre>
windows 7, 32 bit, two jdk, one is 1.5, another is 1.7, google gwt, jetty,
ant, two eclipse, one is kepler, another is luna.
</pre>
for kepler, I set its jdk is 1.5, and use ant to compile and jar, this
works, and eclipse can open the gwt window when debugging.
then i use luna, check out project(gwt project) from cvs, there is error
said the jdk is 1.5 when compiling with ant, therefore I changed the jdk to
1.7 since this project requires this version, eventually compile is ok with
ant. However, when I debug it in eclipse, it opens a gwt window said
unable to compile to jsp, and the error in console is :
<pre>
