Subject: ActionError - java.lang.NummPointer Exception HELP!!!
First, thank you very much in advance for your help.
I am using struts 1.0 and I am getting Null pointer exception when running
validate(Mapping, request) and I am experiencing a coder's block.. if
there's such a thing..
Look at my validate(.., ..) function:
public ActionErrors validate(ActionMapping mapping, HttpServletRequest
request) {
ActionErrors errors = new ActionErrors();
log4.debug("Validate:: arraySize = " + getArraySize());
if (!m_boIsProject && !m_boSigned) {
validateNumbers(errors);
if (errors.empty()) {
validateHours(errors);
}
log4.debug("================================================");
if (errors == null) {
log4.debug("2. error is null...");
errors = new ActionErrors();
}
log4.debug("2. error is not null...");
if (errors.empty()) {
validateComments(errors);
}
}
return errors;
}
I am getting logj logs up till log4.debug("2. error is not null..."),
meaning errors did not become null - of course.. But the thing is, I don't
get the very first log message from validateComments(error), which should
execute as the first code inside the method.
the validate mathod was quite long, but I made some helper functions because
I thought it might solve the proble. - but since I am still using the
reference of errors, it will be basically the same, right? So... should I
create new ActionErrors from my methods and return it? so that my main
validate method does get() to get Iterators and go through it??
Following is my code for validateComments(errors):
private void validateComments(ActionErrors errors) {
// Validate only iff all numbers are of valid hour.
log4.debug("Validate:: No error detected so far... Now checking comment
length validation...");
log4.debug("Validate:: isLengthValid for Sundar hour...");
for (int i=0; i<getArraySize(); i++) {
log4.debug("Validate:: sundayComment["+i+"] = "
+m_strSundayComment[i]);
if (!BusinessRules.isLengthValid(m_strSundayComment[i]))
errors.add("sundayComment["+ i +"]", new
ActionError("error.com.qett.time.invalid.comment.length", "Sunday",
getIndexName(i), BusinessRules.getStringMaxLength()));
}
log4.debug("Validate:: isLengthValid for Sundar hour...");
for (int i=0; i<getArraySize(); i++) {
log4.debug("Validate:: mondayComment["+i+"] = "
+m_strMondayComment[i]);
if (!BusinessRules.isLengthValid(m_strMondayComment[i]))
errors.add("mondayComment["+ i +"]", new
ActionError("error.com.qett.time.invalid.comment.length", "Monday",
getIndexName(i), BusinessRules.getStringMaxLength()));
}
log4.debug("Validate:: isLengthValid for Sundar hour...");
for (int i=0; i<getArraySize(); i++) {
log4.debug("Validate:: tuesdayComment["+i+"] = "
+m_strTuesdayComment[i]);
if (!BusinessRules.isLengthValid(m_strTuesdayComment[i]))
errors.add("tuesdayComment["+ i +"]", new
ActionError("error.com.qett.time.invalid.comment.length", "Tuesday",
getIndexName(i), BusinessRules.getStringMaxLength()));
}
log4.debug("Validate:: isLengthValid for Sundar hour...");
for (int i=0; i<getArraySize(); i++) {
log4.debug("Validate:: wednesdayComment["+i+"] = "
+m_strWednesdayComment[i]);
if (!BusinessRules.isLengthValid(m_strWednesdayComment[i]))
errors.add("wednesdayComment["+ i +"]", new
ActionError("error.com.qett.time.invalid.comment.length", "Wednesday",
getIndexName(i), BusinessRules.getStringMaxLength()));
}
log4.debug("Validate:: isLengthValid for Sundar hour...");
for (int i=0; i<getArraySize(); i++) {
log4.debug("Validate:: thursdayComment["+i+"] = "
+m_strThursdayComment[i]);
if (!BusinessRules.isLengthValid(m_strThursdayComment[i]))
errors.add("thursdayComment["+ i +"]", new
ActionError("error.com.qett.time.invalid.comment.length", "Thursday",
getIndexName(i), BusinessRules.getStringMaxLength()));
}
log4.debug("Validate:: isLengthValid for Sundar hour...");
for (int i=0; i<getArraySize(); i++) {
log4.debug("Validate:: fridayComment["+i+"] = "
+m_strFridayComment[i]);
if (!BusinessRules.isLengthValid(m_strFridayComment[i]))
errors.add("fridayComment["+ i +"]", new
ActionError("error.com.qett.time.invalid.comment.length", "Friday",
getIndexName(i), BusinessRules.getStringMaxLength()));
}
log4.debug("Validate:: isLengthValid for Sundar hour...");
for (int i=0; i<getArraySize(); i++) {
log4.debug("Validate:: saturdayComment["+i+"] = "
+m_strSaturdayComment[i]);
if (!BusinessRules.isLengthValid(m_strSaturdayComment[i]))
errors.add("saturdayComment["+ i +"]", new
ActionError("error.com.qett.time.invalid.comment.length", "Saturday",
getIndexName(i), BusinessRules.getStringMaxLength()));
}
}
Thank you.
