[jboss-jira] [JBoss JIRA] Closed: (JBPM-821) ProcessClassLoader.getResourceAsStream throws JbpmException when the resource is not found in DB

ProcessClassLoader.getResourceAsStream throws JbpmException when the resource is not found in DB ------------------------------------------------------------------------------------------------ Key: JBPM-821 URL: http://jira.jboss.com/jira/browse/JBPM-821 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM 3.1.2 Reporter: Victor Suarez Assigned To: Tom Baeyens Fix For: jBPM jPDL 3.2.2 "ProcessClassLoader.getResourceAsStream(String name)" must return null when the resource is not found <link>http://java.sun.com/j2se/1.4.2/docs/api/java/lang/ClassLoader.htm...;. But when the resource look up must be performed in the DB, if that resource is not found I get a JbpmException. "ProcessClassLoader.getResourceAsStream(String name)" delegates in "fileDefinition.getBytes(name)" for searching the resource, and this calls to "getBytesFromDb(name)", and finally, this calls to "getByteArray(name)", that performs this code: if (byteArray == null) { throw new JbpmException("file '" + name + "' not found in db"); } I think that a possible solution could be: byte[] getBytesFromDb(String name) { byte[] bytes = null; //refactored this line ByteArray byteArray = doGetByteArray(name); if (byteArray != null) bytes = byteArray.getBytes(); return bytes; } ByteArray getByteArray(String name) { //extract method refactoring ByteArray byteArray = doGetByteArray(name); if (byteArray == null) { throw new JbpmException("file '" + name + "' not found in db"); } return byteArray; } //extracted method ByteArray doGetByteArray(String name) { ByteArray byteArray = (ByteArray) (processFiles != null ? processFiles.get(name) : null); return byteArray; } I let with no modifications "getByteArray(String name)" because is referenced in the rest of code. Thanks
