You may need to install the Java Development Tools manually.

Add this update site (if it doesn't exist already):

http://download.eclipse.org/releases/galileo

Then look for Programming Languages -> Eclipse Java Development Tools.  Check the box, click Next and follow the instructions.  Eventually you'll be asked to restart Eclipse.  Do so and then when it loads again you'll have the Java perspective, Plugin-perspective, etc.

Cheers,

Chris

If you want to invoke java methods that are remote though, you might want to use a Java Remoting technology like BlazeDS.

Using a <s:RemoteObject> tag, you could connect to the server and invoke java methods.

Here is a small sample app code that helps me execute a remote java method.

<?xml version="1.0" encoding="utf-8"?>

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

   xmlns:s="library://ns.adobe.com/flex/spark"

   xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"

   creationComplete="ro.getProducts()">

<fx:Script>

<![CDATA[

import mx.controls.Alert;

import mx.messaging.channels.AMFChannel;

import mx.rpc.events.FaultEvent;

import mx.rpc.events.ResultEvent;

protected function ro_resultHandler(event:ResultEvent):void

{

Alert.show(event.result.toString())

}

protected function ro_faultHandler(event:FaultEvent):void

{

Alert.show(event.fault.faultString);

}

]]>

</fx:Script>

<fx:Declarations>

<!-- Place non-visual elements (e.g., services, value objects) here -->

<s:RemoteObject id="ro"

destination="productService"

endpoint="http://localhost:8400/samples"

fault="ro_faultHandler(event)"

result="ro_resultHandler(event)"/>

</fx:Declarations>

</s:Application>

Hope this helps,
