Compilation

Now that we have our Java code, we need to compile it and place it in

a jar file. The specific steps for compiling the code and creating the

jar will vary based on the Java development tools used.

For example, suppose you have Spotfire Miner installed in

D:\Program Files, and you have Sun’s JDK1.4 installed in

D:\java\jdk1.4.0. To compile the example files in the Spotfire Miner

distribution using the Miner.jar in the distribution, first change into

the directory containing the Java source code and then use the

javac

command:

cd "D:\Program Files\TIBCO\miner82\examples"

D:\java\jdk1.4.0\bin\javac -classpath "D:\Program

Files\TIBCO\miner82\tools\splus\java\jre\lib\ext\Miner.jar"

*.java

The directory with the *.java files will now also contain *.class files.

These need to be put into an extension.jar file, which we will then

copy into the extension directory. The

jar command creates a jar

file:

D:\java\jdk1.4.0\bin\jar cvf extension.jar *.class

XML Description Next we need to create the XML description of this node. Let’s label

it as the First Copy Columns node, use the default icons, and specify

two inputs and outputs. The XML to create a new page with a folder

containing this description is:

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

<ExplorerFolder expanded="true"

labelText="Copy Columns">

<ActivityNode

engineClass="FirstCopyEngineNode"

guiClass=

"com.insightful.miner.ActivityNodeModel"

numInputs="2"

numOutputs="2" >

1 2 ... 26 27 28 29 30 31 32 33 34 35 36 ... 97 98
