I am trying to make an applet out of my geotools application and deploy it on Tomcat6. I just wanted to know if someone has faced this error before. When I run the applet in Eclipse, it runs well. Once I deploy it on Tomcat server and run it on the shell using appletviewer, it gives a NullPointerException on the line where I read a shapefile from the File system. (Using a FileDataStore to read contents from the 'File' object). Apparently, my datastore object remains null.
My applet has all the permissions to access the file system as specified in the policy file. Please let me know if you know a fix for this. Here is the exact code where the error lies.
File file = new File("tl_2010_48015_roads.shp");
FileDataStore store = null;
try {
store = FileDataStoreFinder.getDataStore(file); // store remains NULL
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Just for reference, my Web project has the following structure.
Proj-Name
JAVA Resources
src ( here is my Geotools code)
WebContent
index.html
shpfiles( where my shapefile is present)
Thank You.
