How to use the Java embedding activity in BPel

Question

hi all,
How to use the java embedding activity in BPEL
pls can u provide sample example

Answer 1

1 Use [Oracle BPEL Process Manager Client Java API Reference|http://download-uk.oracle.com/docs/cd/B31017_01/integrate.1013/b28986/overview-summary.html] and especially [com.collaxa.cube.engine.ext|http://download-uk.oracle.com/docs/cd/B31017_01/integrate.1013/b28986/com/collaxa/cube/engine/ext/BaseBPELXExecLet.html]
Instead of System.Out.println use addAuditTrailEntry(java.lang.String message)
2. If you want to import a package write in code (Source View) of bpel process
+<bpelx:exec import="package_name"/>+ for example +<bpelx:exec import="java.util.regex.Matcher"/>+
example 1:
String bodyAsString;
StringBuffer myStringBuffer = new StringBuffer();
try {
bodyAsString = (String)getVariableData("BodyString");
addAuditTrailEntry("bodyAsString1: "+ bodyAsString);
Pattern pattern = Pattern.compile("goodDay");
Matcher matcher= pattern.matcher(bodyAsString);
while (matcher.find()) {   
matcher.appendReplacement(myStringBuffer, "shitDay");
matcher.appendTail(myStringBuffer);
bodyAsString = myStringBuffer.toString();
addAuditTrailEntry("bodyAsString2: "+ bodyAsString);
} catch (Exception ex) {
addAuditTrailEntry("Failed+bodyAsString",ex.getMessage());
I put in code (Source View) the following
<bpelx:exec import="java.util.regex.Matcher"/>
<bpelx:exec import="java.util.regex.Pattern"/>
example2:
Object temp;
try {
temp = ((XMLElement)getVariableData("inputVariable","payload","/ns2:FiscalisMessage/ns2:Body")).getChildNodes().item(1);
setVariableData("AdjReceipt",temp);
addAuditTrailEntry("ok",temp.toString());
catch (Exception ex) {
addAuditTrailEntry("Failed :",ex);
I put in code (Source View) the following
<bpelx:exec import="oracle.xml.parser.v2.XMLElement"/>
