# Loan Approval WS-BPEL Business Process
This project implements the Loan Approval Process using WS-BPEL 2.0 and WSDL 1.1. The implementation is deployable in a BPEL engine. I have developed and tested the process with some versions of [Apache ODE](http://ode.apache.org) 1.3.x.
The implementation under the folder `resources` consists of a `.bpel` file that describes the main business logic of the process and a number of `.wsdl` files that specifies various functions provided by different Web services.
## Requirements
- [Apache ODE 1.3.x](http://ode.apache.org) (please see the [notes on Apache ODE](#apache-ode))
- [Apache Ant](https://ant.apache.org)
## Deploying/Running
The local path to the Apache ODE repository is defined in the file `project.properties`. This value must reflect the actual location of Apache ODE in your host/computer.
```properties
ode.deploy.dir=/usr/local/opt/tomcat/libexec/webapps/ode/WEB-INF/processes
```
### Compiling
```sh
ant process.compile
```
### Deploying
```sh
ant process.deploy
```
### Packaging
```sh
ant process.package
```
## Notes
* The legal delay before the customer makes a decision is current set at `5` seconds.
```xml
'P0Y0M0DT0H0M5S'
```
* The legal time-out is currently set at `30` seconds.
```xml
'P0Y0M0DT0H0M30S'
...
```
These values are merely used for demonstrating purposes only.
#### Apache ODE 1.3.3
If a process has multiple consecutive invocations to a service, that will raise an exception via Apache Axis 2 "`axis2.AxisFault`" regarding _"two services cannot have same name"_ (see https://issues.apache.org/jira/browse/ODE-647 for more information).
Applying the corresponding patch and rebuilding Apache ODE from its source will fix the issue.
### Apache ODE 1.3.4 & 1.3.5
These two engines throw a rather cryptic error message `java.util.regex.PatternSyntaxException: Dangling meta character '*' near index 0` as following.
```

#### Apache ODE 1.3.6 & 1.3.7
These engines work perfectly fine for the Loan Approval BPEL process. There are no known errors/bugs so far.
#### Apache ODE 1.3.8
The XMl messages sent by Apache ODE 1.3.8 to LoanFile services are broken. This issue does not happen with other versions.
