Regular Expression or Common Validator Utility Class
Hi all,
Just to check whether is there a common validator utility class that make use of Regular Expression for input and output validation in Web Dynpro?
Thank a lot
Regards
Hi
U can make use of following classes for validating a regular expression.
java.util.regex.Pattern
java.util.regex.Match

That, however, is in theory. I've posted, and immediately seen something that needed editing, only to find NO Replies, yet the Edit button is no longer available, only seconds later. Still, in that same thread, I'd have the Edit button from older posts, to which there had also been no Replies even after several days/weeks. Found one that had to be over a month old, and Edit was still there.
Do not know the why/how of this behavior. At first, I thought that maybe there WAS a Reply, that "ate" my Edit button, but had not Refreshed on my screen. Refresh still showed no Replies, just no Edit either. In those cases, I just Reply and mention the [Edit].
Also, it seems that the buttons get very scrambled at times, and Refresh does not always clear that up. I end up clicking where I "think" the right button should be and hope for the best. Seems that when the buttons do bunch up they can appear at random around the page, often three atop one another, and maybe one way the heck out in left-field.
While I'm on a role, it would be nice to be able to switch between Flattened and Threaded Views on the fly. Each has a use, and having to go to Options and then come back down to the thread is a very slow process. Jive is probably incapable of this, but I can dream.

Help With Regular Expression In Apex Validation
Apex 3.2
There is a validation type of regular expression in apex, but I have never used regular expression before,
so a little help is appreciated.
I need to validate a field. It is only allowed to contain alpha characers, numbers, spaces and the - (dash) character.
I have tried several times to get this working
eg
[[:alpha:]]*[[:digit:]]*[[:space:]]*[-]*
^[[:alpha:][:digit:][:space:]-]+?
and others, but just can't to get the syntax correct.
Can someone help me with this please
GusExample:

Regular expressions in Rename Wizard Utility
Hi guys,
Does anyone know how to use regular expressions (and it possible) in OBIEE's internal "Rename Wizard" utility. For example, I have the following columns:
% Change Variance ColumnName1
% Change Variance ColumnName2
% Change Variance ColumnName3
and I want them to be
Variance ColumnName1 % Change
Variance ColumnName2 % Change
Variance ColumnName3 % Change
Is there another way to do this except than by hand? Your help is appreciated.user447618,

Help with Regular Expression for field validation
I'm fairly new to using regular expressions and using Acrobat. This is probably a simple question, but I've been unable to figure it out.
I have a text field on a PDF that I would like to be 9 characters in length. The first 2 characters can only be alphanumeric, the last 7 characters can only be numeric.
At first I was using the following, which allows all the characters to be alphanumeric:
var re = /^[A-Za-z0-9 :\\_]$/;
if (event.change.length >0) {
if (event.willCommit == false) {
if (!re.test(event.change)) {
event.rc = false
That works fine, but it's not quite what I needed. With some assistance I changed it (see below) to fit what I was looking for. However, this didn't work; it prevents anything from being entered in the field:
var re = /^[A-Za-z0-9]{2}\d{7}$/;
if (event.change.length >0) {
if (event.willCommit == false) {
if (!re.test(event.change)) {
event.rc = false
Any help would be greatly appreciated.
Thanks...Here's a function you can call form the field's custom Format script. It should be placed in a document-level JavaScript:
function custom_ks1() {
// Define non-commited regular expression
var re = /^[A-Za-z0-9]{0,2}([0-9]{0,7})?$/;
// Get all of the characters the user has entered
var value = AFMergeChange(event);
// Allow field to be cleared
if(!value) return;
if (event.willCommit) {
// Define commited regular expression
var re = /^[A-Za-z0-9]{2}[0-9]{7}$/;
if (!re.test(value)) { // If final value doesn't match, alert user
app.alert("Your error message goes here.");
// event.rc = false
} else { // not commited
// Only allow characters that match the regular expression
event.rc = re.test(value);
Call it like this:
// Custom Keystroke script
custom1_ks(); -
Regular Expression back-reference in character class
I am trying to capture quoted text (excluding the quotes) with the following pattern:
"(['\"])([^\\1]+)\\1"
The input string might look like:
"That's strange"
or:
'valid "regex" pattern'
I get an exception when trying to compile the pattern, because of the back-reference within character-class brackets: [^\1]
This pattern worked with the org.apache.oro package. Is this a bug in the 1.4 Pattern class? Can you offer an alternative solution?
Thanks,
TonyThanks for the reply. Apparently, my pattern wasn't working as I thought with ORO. The pattern you suggested, however, wouldn't do what I need either, because it would match anything between the first and last quote character. I don't want to match the string you included in your reply, because it includes the same quote character that encloses the entire string. If you think about my pattern again, you'll notice that the first capture group should match either a single or double quote character. Then the back-reference should be the exact character (single character) that was matched and captured. So the second capture group should be any number of characters, as long as they don't match the first capture group character, followed by the exact string matched in the first capture group (the single character). You probably are aware that when one or more characters are included in square brackets [], that it specifies a match of a single character that is found anywhere within that character class. So if the first capture group happened to match more than one character (impossible due to the pattern in that grouping), the following character class [^\1] should match any character EXCEPT any of the ones matched in the first capture group...right? There must be a bug in ORO that doesn't match correctly per my description, but it seems there is a bug in JDK 1.4 Pattern that will not even compile it. Just to re-iterate...if \1 matched "abc", [^\1] should match any single character EXCEPT a or b or c. I can get what I want, though, if I do it in 2 matches:
Pattern pat = Pattern.compile("(['\"])(.*)");
Matcher mat = pat.matcher(sText);
mat.matches();
String sQuote = mat.group(1);
String sRem = mat.group(2);
pat = Pattern.compile("([^" + sQuote + "]*)" + sQuote);
mat = pat.matcher(sRem);
mat.matches();
String sWhatIWanted = mat.group(1);
Thanks,

Using regular expressions for validating time fields
Similar to my problem with converting a big chunk of validation into smaller chunks of functions I am trying to use Regular Expressions to handle the validation of many, many time fields in a flexible working time sheet.
I have a set of FormCalc scripts to calculate the various values for days, hours and the gain/loss of hours over a four week period. For these scripts to work the time format must be in HH:MM.
Accessibility guidelines nix any use of message box pop ups so I wanted to get around this by having a hidden/visible field with warning text but can't get it to work.
So far I have:
var r = new RegExp(); // Create a new Regular Expression Object
r.compile ("^[00-99]:\\] + [00-59]");
var result = r.test(this.rawValue);
if (result == true){
true;
form1.flow.page.parent.part2.part2body.errorMessage.presence = "visible";
else (result == false){
false;
form1.flow.page.parent.part2.part2body.errorMessage.presence = "hidden";
Any help would be appreciated!Date and time fields are tricky because you have to consider the formattedValue versus the rawValue. If I am going to use regular expressions to do validation I find it easier to make them text fields and ignore the time patterns (formattedValue). Something like this works (as far as my very brief testing goes) for 24 hour time where time format is HH:MM.
// form1.page1.subform1.time_::exit - (JavaScript, client)
var error = false;
form1.page1.subform1.errorMsg.rawValue = "";
if (!(this.isNull)) {
var time_ = this.rawValue;
if (time_.length != 5) {
error = true;
else {
var regExp = /^([01]?[0-9]|2[0-3]):[0-5][0-9]$/;
if (!(regExp.test(time_))) {
error = true;
if (error == true) {
form1.page1.subform1.errorMsg.rawValue = "The time must be in the format HH:MM where HH is 00-23 and MM is 00-59.";
form1.page1.subform1.errorMsg.presence = "visible";

Regular Expression Class in RoboHelp
Is there any class in RoboHelp object model for working with regular expressions? Or maybe a class for find and change option?
In Javascript there is RegExp class. Does RoboHelp have the same?I suspect you have a development background which I do not have. Regular expressions work just fine from the tools I have used (as above plus dnGrep) but I think you want to create a script of some sort that takes in regular expressions, effectively replacing the tools I have used to run the expressions. I am sorry I cannot help you on that Charlotte.
Curiosity makes me ask why you have to do this with your own script rather than the tools I have used.

Regular expressions to parse arithmetic expression
Hello,
I would like to parse arithmetic expressions like the following
"5.2 + cos($PI/2) * -5"where valid expression entities are numbers, operations, variables and paranthesis. Until now I have figured out some regular expressions to match every type of entities that I need, and combine them into one big regex supplied to a pattern and matcher. I will paste some code now to see what I wrote:
public class RegexTest {
/** A regular expression matching numeric expressions (floating point numbers) */
private static final String REGEX_NUMERIC = "(-?[0-9]+([0-9]*|[\\.]?[0-9]+))";
/** A regular expression matching a valid variable name */
private static final String REGEX_VARIABLE = "(\\$[a-zA-Z][a-zA-Z0-9]*)";
/** A regular expression matching a valid operation string */
public static final String REGEX_OPERATION = "(([a-zA-Z][a-zA-Z0-9]+)|([\\*\\/\\+\\-\\|\\?\\:\\@\\&\\^<>'`=%#]{1,2}))";
/** A regular expression matching a valid paranthesis */
private static final String REGEX_PARANTHESIS = "([\\(\\)])";
public static void main(String[] args) {
String s = "5.2 + cos($PI/2) * -5".replaceAll(" ", "");
Pattern p = Pattern.compile(REGEX_OPERATION + "|" + REGEX_NUMERIC + "|" + REGEX_VARIABLE + "|" + REGEX_PARANTHESIS);
Matcher m = p.matcher(s);
while (m.find()) {
System.out.println(m.group());
}The output is
5
2
+
cos
$PI
2
5There are a few problems:
1. It splits "5.2" into "5" and "2" instead of keeping it together (so there might pe a problem with REGEX_NUMERIC although "5.2".matches(REGEX_NUMERIC) returns true)
2. It interprets "... * -5" as the operation " *- " and the number "5" instead of " * " and "-5".
Any solution to solve these 2 problems are greately appreciated. Thank you in advance.

import java.util.regex.*;
class Test {
private static final String REGEX_NUMERIC = "(((?<=[-+*/(])|(?<=^))-)?\\d+(\\.\\d+)?";
private static final String REGEX_VARIABLE = "\\$[a-zA-Z][a-zA-Z0-9]*";
public static final String REGEX_OPERATION = "[a-zA-Z][a-zA-Z0-9]+|[-*/+|?:@&^<>'`=%#]";
private static final String REGEX_PARANTHESIS = "[()]";
public static void main(String[] args) {
String[] tests = {
"abs(-5) + -3",
"sqrt(abs($x=1 + -10))",
"$e * -1 + (2 - sqrt(4))",
"sin($PI/4) - 3",
"sin($PI/4) - -3 - (-4)",
"-2-4" // minus sign at the start of the expression
Pattern p = Pattern.compile(REGEX_NUMERIC + "|" + REGEX_OPERATION + "|" + REGEX_VARIABLE + "|" + REGEX_PARANTHESIS);
for(String s: tests) {
s = s.replaceAll("\\s", "");
Matcher m = p.matcher(s);
System.out.printf("%-21s-->", s);
while (m.find()) {
System.out.printf("%6s", m.group());
System.out.println();
}Note that since Java's regex engine does not support "variable length look behinds", you will need to remove the white spaces from your expression, otherwise REGEX_NUMERIC will go wrong if a String looks like this:
"1 - - 1"Good luck! -
Regular Expressions find and replace
Hi ,
I have a question on using Regular Expressions in Java(java.util.regex).
Problem Description:
I have a string (say for example strHTML) which contains the whole HTML code of a webpage. I want to be able to search for all the image source tags and check whether they are absolute urls to the image source(for eg. <img src="www.google.com/images/logo.gif" >) or relative(for eg. <img src="../images/logo.gif" >).
If they are realtive urls to the image path, then I wish to replace them with their absolute urls throughout the webpage(in this case inside string strHTML).
I have to do it inside a servlet and hence have to use java.
I tried . This is the code. It doesn't match and replace and goes inside an infinite loop i.e probably the pattern matches everything.
//Change all images to actual http addresses FOR example change src="../images/logo.gif" to src="http://www.google.com/../images/logo.gif"
String ddurl="http://www.google.com/";
String strHTML=" < img src=\"../images/logo.gif\" alt=\"Google logo\">";
Pattern p = Pattern.compile ("(?i)src[\\s]*=[\\s]*[\"\']([./]*.*)[\"\']");
Matcher m = p.matcher (strHTML);
while(m.find())
m.replaceAll(ddurl+m.group(1));
what is wrong in this?
Thanks,
RajivRight, here's the full monte (whatever that means):import java.util.regex.*;
public class Test1
public static void main(String[] args)
String domain = "http://www.google.com/";
String strHTML =
" < img src=\"images/logo.gif\" alt=\"Google logo\">\n" +
" <img alt=\"Google logo\" src=images/logo.gif >\n" +
" <IMG SRC=\"/images/logo.gif\" alt=\"Google logo\">\n" +
" <img alt=\"Google logo\" src=../images/logo.gif>\n" +
" <img src=http://www.yahoo.com/images/logo.gif alt=\"Yahoo logo\">";
String regex =
"(<\\s*img.+?src\\s*=\\s*) # Capture preliminaries in $1. \n" +
"(?: # First look for URL in quotes. \n" +
" ([\"\']) # Capture open quote in $2. \n" +
" (?!http:) # If it isn't absolute... \n" +
" /?(.+?) # ...capture URL in $3 \n" +
" \\2 # Match the closing quote \n" +
" | # Look for non-quoted URL. \n" +
" (?!http:) # If it isn't absolute... \n" +
" /?([^\\s>]+) # ...capture URL in $4 \n" +
Pattern p = Pattern.compile(regex, Pattern.CASE_INSENSITIVE | Pattern.COMMENTS);
Matcher m = p.matcher(strHTML);
StringBuffer sbuf = new StringBuffer();
while (m.find())
String relURL = m.group(3) != null ? m.group(3) : m.group(4);
m.appendReplacement(sbuf, "$1\"" + domain + relURL + "\"");
m.appendTail(sbuf);
System.out.println(sbuf.toString());
}First off, observe that I'm using free-spacing (or "COMMENTS") mode to make the regex easier to read--all the whitespace and comments will be ignored by the Pattern compiler. I also used the CASE_INSENSITIVE flag instead of an embedded (?i), just to remove some clutter. By the way, your second (?i) was redundant; the first one would remain in effect until "turned off" with a (?-i). Another way to localize a flag's effect by using it within a non-capturing group, e.g., (?i:img).
As jaylogan said, the best way to filter out absolute URL's is by using a negative lookahead, and that's what I've done here. The problem of optional quotes I addressed by trying to match first with quotes, then without. The all-in-one approach might work with URL's, since they can't (AFAIK) contain whitespace anyway, but the alternation method can be used to match any attribute/value pair. It's also, I feel, easier to understand and maintain. Unfortunately, it also means that you can't use replaceAll(), since you have to determine which alternative matched before doing the replacement, but the long version is still pretty simple (especially when you can just copy it from the javadoc for the appendReplacement() method, as I did). -

Phone Number - Regular Expression
I'm trying to validate a phone number using regular expressions.
My validation appears as the following:
IF REGEXP_LIKE ( :P10_PHONE, '^\(?[[:digit:]]{3}\)?[-. ]?[[:digit:]]{3}[-. ]?[[:digit:]]{4}$' ) THEN
RETURN TRUE;
ELSE
RETURN FALSE;
END IF;
The problem I noticed is that it returned true even if I typed in a phone number like this:
(555 123-4567
Is there a way to tell it that if one parenthesis is there that the other one should be there as well? Or should I just do an instr if the regexp_like returns true and double-check it myself?
Thanks,
ChadYou can use the OR operator (|)...
'^(\([[:digit:]]{3}\)|[[:digit:]]{3})[-. ]?[[:digit:]]{3}[-. ]?[[:digit:]]{4}$'

Regular Expression for multiple emails
Hi! I have a jsp page that has an inputTextArea so the user can enter multiple email addresses. In the backing bean (after they submit) I tokenize thru it and add email addresses to an arraylist. I want to validate that they are correct format before adding to arraylist, but how do I do that in the backing bean? All regular expression examples I have seen are in jsp page and javascript. Any sample code / suggestions would be greatly appreciated - as I have not had much experience with regular expressions. Thanks!
Hi,
this could be a solution for your problem; I've created two regular expressions to find valid email- and http-addresses in fulltext or xml-text fields ;-)

Namburi,
When you said you used the Reg Exp tool, did you use it only as
preconfigured by the iMT migrate application wizard?
Because the default configuration of the regular expression tool will only
target the files in your ND project directories. If you wish to target
classes outside of the normal directory scope, you have to either modify the
"Source Directory" property OR create another instance of the regular
expression tool. See the "Tool" menu in the iMT to create additional tool
instances which can each be configured to target different sets of files
using different sets of rules.
Usually, I utilize 3 different sets of rules files on a given migration:
spider2jato.xml
these are the generic conversion rules (but includes the optimized rules for
ViewBean and Model based code, i.e. these rules do not utilize the
RequestManager since it is not needed for code running inside the ViewBean
or Model classes)
I run these rules against all files.
See the file download section of this forum for periodic updates to these
rules.
nonProjectFileRules.xml
these include rules that add the necessary
RequestManager.getRequestContext(). etc prefixes to many of the common
calls.
I run these rules against user module and any other classes that do not are
not ModuleServlet, ContainerView, or Model classes.
appXRules.xml
these rules include application specific changes that I discover while
working on the project. A common thing here is changing import statements
(since the migration tool moves ND project code into different jato
packaging structure, you sometime need to adjust imports in non-project
classes that previously imported ND project specific packages)
So you see, you are not limited to one set of rules at all. Just be careful
to keep track of your backups (the regexp tool provides several options in
its Expert Properties related to back up strategies).

Thanks Matt, Mike, Todd
This is a great input for our migration. Though we used the existing
Regular Expression Mapping tool, we did not change this to meet our
own needs as mentioned by Mike.
We would certainly incorporate this to ease our migration.

Great response. By the way, the Regular Expression Tool uses thePerl5 RE
syntax as implemented by Apache OROMatcher. If you're doing lotsof these
sorts of migration changes manually, you should definitely buy theO'Reilly
book "Mastering Regular Expressions" and generate some rules toautomate the
conversion. Although they are definitely confusing at first,regular
expressions are fairly easy to understand with some documentation,and are
superbly effective at tackling this kind of migration task.

Also, (and Matt's document may mention this)
Please bear in mind that this statement is not totally correct:
Since the migration tool does not do much of conversion for
these
utilities we have to do manually.Remember, the iMT is a SUITE of tools. There is the extractiontool, and
the translation tool, and the regular expression tool, and severalother
smaller tools (like the jar and compilation tools). It is correctto state
that the extraction and translation tools only significantlyconvert the
primary ND project objects (the pages, the data objects, and theproject
classes). The extraction and translation tools do minimumtranslation of the
User Module objects (i.e. they repackage the user module classes inthe new
jato module packages). It is correct that for all other utilityclasses
which are not formally part of the ND project, the extraction and
translation tools do not perform any migration.
However, the regular expression tool can "migrate" any arbitrary
file
(utility classes etc) to the degree that the regular expressionrules
correlate to the code present in the arbitrary file. So first andforemost,
if you have alot of spider code in your non-project classes youshould
consider using the regular expression tool and if warranted adding
additional rules to reduce the amount of manual adjustments thatneed to be
made. I can stress this enough. We can even help you write theregular
expression rules if you simply identify the code pattern you wish to
convert. Just because there is not already a regular expressionrule to
match your need does not mean it can't be written. We have notnearly
exhausted the possibilities.
For example if you say, we need to convert
CSpider.getDataObject("X");
To
RequestManager.getRequestContext().getModelManager().getModel(XModel.class);
Maybe we or somebody else in the list can help write that regularexpression if it has not already been written. For instance in thelast
updated spider2jato.xml file there is already aCSpider.getCommonPage("X")
rule:
<!--getPage to getViewBean-->
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[CSpider[.\s]*getPage[\s]*\(\"([^"]*)\"]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[CSpider[.\s]*getPage[\s]*\(\"([^"]*)\"]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[getViewBean($1ViewBean.class]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>
Following this example a getDataObject to getModel would look
like this:
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[CSpider[.\s]*getDataObject[\s]*\(\"([^"]*)\"]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[CSpider[.\s]*getDataObject[\s]*\(\"([^"]*)\"]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[getModel($1Model.class]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>
In fact, one migration developer already wrote that rule andsubmitted it
for inclusion in the basic set. I will post another upgrade to thebasic
regular expression rule set, look for a "file uploaded" posting.Also,
please consider contributing any additional generic rules that youhave
written for inclusion in the basic set.
Please not, that in some cases (Utility classes in particular)
the rule
application may be more effective as TWO sequention rules ratherthan one
monolithic rule. Again using the example above, it will convert
CSpider.getDataObject("Foo");
To
getModel(FooModel.class);
Now that is the most effective conversion for that code if that
code is in
a page or data object class file. But if that code is in a Utilityclass you
really want:
>
RequestManager.getRequestContext().getModelManager().getModel(FooModel.class
So to go from
getModel(FooModel.class);
To
RequestManager.getRequestContext().getModelManager().getModel(FooModel.class
You would apply a second rule AND you would ONLY run this rule
against
your utility classes so that you would not otherwise affect yourViewBean
and Model classes which are completely fine with the simplegetModel call.
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[getModel\(]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[getModel\(]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[RequestManager.getRequestContext().getModelManager().getModel(]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>
A similer rule can be applied to getSession and other CSpider APIcalls.
For instance here is the rule for converting getSession calls toleverage
the RequestManager.
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[getSession\(\)\.]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[getSession\(\)\.]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[RequestManager.getSession().]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>

Namburi,
I will post a document to the group site this evening which has
the
details
on various tactics of migrating these type of utilities.
Essentially,
you
either need to convert these utilities to Models themselves or
keep the
utilities as is and simply use the
RequestManager.getRequestContext.getModelManager().getModel()
to statically access Models.
For CSpSelect.executeImmediate() I have an example of customhelper
method
as a replacement whicch uses JDBC results instead of
CSpDBResult.

Subject: [iPlanet-JATO] Use Of models in utility classes
Hi All,
In the present ND project we have lots of utility classes.
These
classes in diffrent directory. Not part of nd pages.
In these classes we access the dataobjects and do themanipulations.
So we access dataobjects directly like
CSpider.getDataObject("do....");
and then execute it.
Since the migration tool does not do much of conversion forthese
utilities we have to do manually.
My question is Can we access the the models in the postmigration
sameway or do we need requestContext?
We have lots of utility classes which are DataObjectintensive. Can
someone suggest a better way to migrate this kind of code.
Thanks

[email protected]Namburi,
When you said you used the Reg Exp tool, did you use it only as
preconfigured by the iMT migrate application wizard?
Because the default configuration of the regular expression tool will only
target the files in your ND project directories. If you wish to target
classes outside of the normal directory scope, you have to either modify the
"Source Directory" property OR create another instance of the regular
expression tool. See the "Tool" menu in the iMT to create additional tool
instances which can each be configured to target different sets of files
using different sets of rules.
Usually, I utilize 3 different sets of rules files on a given migration:
spider2jato.xml
these are the generic conversion rules (but includes the optimized rules for
ViewBean and Model based code, i.e. these rules do not utilize the
RequestManager since it is not needed for code running inside the ViewBean
or Model classes)
I run these rules against all files.
See the file download section of this forum for periodic updates to these
rules.
nonProjectFileRules.xml
these include rules that add the necessary
RequestManager.getRequestContext(). etc prefixes to many of the common
calls.
I run these rules against user module and any other classes that do not are
not ModuleServlet, ContainerView, or Model classes.
appXRules.xml
these rules include application specific changes that I discover while
working on the project. A common thing here is changing import statements
(since the migration tool moves ND project code into different jato
packaging structure, you sometime need to adjust imports in non-project
classes that previously imported ND project specific packages)
So you see, you are not limited to one set of rules at all. Just be careful
to keep track of your backups (the regexp tool provides several options in
its Expert Properties related to back up strategies).
