Invoking Java from BPEL
Another option to call Java from BPEL is using SOAP to wrap the Java code as a web
service and invoke the web service from BPEL
In order to use a Java method from an already created Java project, you could per-
form the following steps:
1. Create a
.jar
file of your Java project.
2. To use a Java class from the
.jar
file inside the BPEL process, copy the
JAR in the same project's
SCA-INF/lib
folder and include the JAR by
going to
Libraries and Classpath
.
3. Use the
Java Embedding
activity for writing Java programs to invoke the
method from the
.jar
file.
4. Use
import
statements inside the source code of BPEL to import the
Java class. Use the
import
attribute of
bpelx:exec
for importing Java
classes and libraries. Examples are listed as follows:
<bpelx:exec import="java.util.*"/>
<bpelx:exec import="myjavaprogram.*"/>
