JNI Problem

2013-10-29 Thread Sean

Hey guys, I read the documentation on JNI and I think what I'm doing is 
correct, but its not working. I'm trying to get values from JAVA into 
Javascript. 

Code Snippet:
[...]
/**
 * 
 * @return
 */
public String getColorScale()
{
int selIndex =m_colorBox.getSelectedIndex();
return m_colorBox.getItemText(selIndex);
}

/**
 * 
 * @return TMS URL for OSM cyclemap
 */
private static native JSObject getCIDBUrl(CIDBViewer p_valHolder) /*-{
function get_my_gwt_url(bounds) {
var res = this.map.getResolution();

var x = Math.round((bounds.left - this.maxExtent.left)
/ (res * this.tileSize.w));
var y = Math.round((this.maxExtent.top - bounds.top)
/ (res * this.tileSize.h));
var z = this.map.getZoom();
if(z12)
{
return http://127.0.0.1:/images/missing.png;;
}
var left = bounds.left;
var right = bounds.right;
var top = bounds.top;
var bottom = bounds.bottom;
//Call the JAVA side to get these values
var minVal = 0;
var maxVal = 10;
* var colorScale 
= p_valhold...@com.ll.cidb.client.CIDBViewer::getColorScale();*
url = http://127.0.0.1:/cidbviewer/map?res=; + res + z= + z
+ left= + left + right= + right + top= + top
+ bottom= + bottom
+cs=+ colorScale
+min=+minVal
+max=+maxVal;
return url;
}

return get_my_gwt_url;
}-*/;

[...]


So you can see I have a simple java method that gets the value out of a 
ListBox. I want to pass that value into the JavaScript function so I can 
send it to my server. However, when I get to the server the value of 
colorScale is:
[function () {  var result = __static(dispId, this);  if 
(result[0]) {throw result[1];  } else {return 
result[1];  }}]


I've tried this instead of passing the java instance. That didn't work 
either.

Any ideas?

You are missing an extra () it should read:
*var colorScale = p_valhold...@com.ll.cidb.client.CIDBViewer
::getColorScale()();*
*
