I want to mark some data on google map.
I use eclipse Java EE and xml file is in the same workspace;(workspace_jsp).

xml file:

<csv_data>
<row>
<time>10:01:43</time>
<latitude>37.4805016667</latitude>
<longitude>126.952741667</longitude>
<pdistance>0.000555</pdistance>
<totaldistance>0.000555</totaldistance>
<sectionspray>3343.0</sectionspray>
</row>
<row>
<time>10:01:57</time>
<latitude>37.4807483333</latitude>
<longitude>126.952753333</longitude>
<pdistance>0.027396</pdistance>
<totaldistance>0.027951</totaldistance>
<sectionspray>3320.0</sectionspray>
</row>

my code is
