Seems like I use this mail group without giving enough thoughts to problems.. If anyone has taken time to read my post about the error messages, I was ignorant. The logs from the third method were not generated because validation functions I used in my second method was wrong - so third method was never called, since error.empty() was false. Although I am still getting the nllpointer exception, I am very sure that it's my configuration problem. I was kinda lost in my two previous posts cause I though my computer was lying to me - I fell that way kinda often. I will make sure that my future posts are the ones that I have given enough thoughts to. Thank you. Jason H.

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.
