Soon I'll modify EJBProviderUtil to read a system property provided at runtime
(eg. -Djumpstart.ejb-provider=OPENEJB_4_LOCAL), because it's getting too hard
to keep EJBProviderUtil's detection technique working reliably.
public static EJBProviderEnum detectEJBProvider(Logger logger) {
EJBProviderEnum ejbProvider = null;
String ejbProviderStr = null;
try {
ejbProviderStr = System.getProperty(PROPERTY_EJB_PROVIDER);
if (ejbProviderStr == null) {
throw new IllegalStateException("System property \"" +
PROPERTY_EJB_PROVIDER
+ "\" not found. Please set it to one
of: {" + getAllowedValuesAsStr() + "}.");
}
ejbProvider = EJBProviderEnum.valueOf(ejbProviderStr);
}
catch (IllegalStateException e) {
throw e;
}
catch (SecurityException e) {
throw new IllegalStateException("Failed to get system property
\"" + PROPERTY_EJB_PROVIDER + "\": " + e);
}
catch (Exception e) {
throw new IllegalStateException("Found system property \"" +
PROPERTY_EJB_PROVIDER + "\" equals \""
+ ejbProviderStr + "\", expected one of: {" +
getAllowedValuesAsStr() + "}.");
}
return ejbProvider;
}
private static String getAllowedValuesAsStr() {
String valuesStr = "";
EJBProviderEnum[] values = EJBProviderEnum.values();
for (EJBProviderEnum ejbProviderEnum : values) {
valuesStr += "\"" + ejbProviderEnum.name() + "\", ";
}
return valuesStr.substring(0, valuesStr.lastIndexOf(","));
}
