问题
I would like to launch some external java class or jar from my project. But i'd like to use the Bo class from my web app project. I'd like to load them in my main class but i get some weird error.
I run a clean install to get a .war and a .jar with maven. Until that everything works fine.
To get the .jar with dependencies i use :
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<archive>
<manifest>
<mainClass>com.clb.genomic.lyon.external.MainExternal</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-my-jar-with-dependencies</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
Inside my war, i have a bean who makes a call via Runtime.getRuntime.exec to a main class.
public void throwAnalyse(){
System.out.println("->I call my function");
try {
String[] command= {"java","-jar", "/Users/JP/git/CleanOmicsTracer/target/CleanOmicsTracer-jar-with-dependencies.jar"};
Process p = Runtime.getRuntime().exec(command);
////////////////////////////////////////////
//test for remote command
String line;
BufferedReader bri = new BufferedReader(new InputStreamReader(p.getInputStream()));
BufferedReader bre = new BufferedReader(new InputStreamReader(p.getErrorStream()));
while ((line = bri.readLine()) != null) {
System.out.println(line);
}
bri.close();
while ((line = bre.readLine()) != null) {
System.out.println(line);
}
bre.close();
p.waitFor();
} catch (IOException e) { e.printStackTrace();
} catch (InterruptedException e) { e.printStackTrace(); }
System.out.println("End of programme");
}
My main class :
public class MainExternal {
public static void main( String[] args ) throws Exception{
ApplicationContext appContext = new ClassPathXmlApplicationContext( "classpath:webConfiguration/applicationContext.xml");
ProjectBo projectBo = (ProjectBo) appContext.getBean("projectBo");
System.out.println("-> Im 'in ");
/************* PRINT OUT *************/
Project project = projectBo.findByNameOfStudy("Profiler");
List<User> listUser = (List<User>) projectBo.findUsers(project);
for (User myUser : listUser) {
System.out.println("User :"+myUser.getFirstname());
}
}
This is the error i get ...
