String/Double Converter on different environments [duplicate] - jsf

I want to know how to set the default decimal separator on my JSF application. I have some <h:inputText> that I need to format as money, with 2 decimals. Right now the decimal separator used by default is the comma , and this gives me an error when I do some operations on save. I don't know if I can set the decimal separator to be used everytime that I use <f:convertNumber> tag.
I tried to use this:
<f:convertNumber pattern="########0.00" groupingUsed="false" />
but it still sets the comma as decimal separator.

The default decimal separator depends on the locale used. You can set it in 2 ways:
On a per-view basis by the locale attribute of the <f:view> tag:
<f:view locale="#{bean.locale}">
On a per-converter basis by the locale attribute of the <f:convertNumber> tag:
<f:convertNumber locale="#{bean.locale}" />
It's unclear what locale you're targeting, but the use of . as fraction separator is typical for US dollars with a locale of en-US, for example. So you need to set it as such:
<f:convertNumber type="currency" currencySymbol="$" locale="en-US" />
It can also be obtained from a java.util.Locale bean property.
<f:convertNumber type="currency" currencySymbol="$" locale="#{bean.locale}" />
Note that I used type="currency", that's more self-documenting.

Force to use comma as a decimal separator in inputText field

I'm having a inputText where a number having a comma as a decimal separator is expected. The backend amount field is a BigDecimal, so the actual number going to the backend should be in the form 100.00 while I want the UI to show 100,00 and not accept 100.00.
I have looked at the inputNumber component which kinda does what I want, but we do not have that dependency in our project, so it's out of discussion.
I have also tried adding <f:convertNumber pattern="#0,00" />, but that does not help or I don't know how to use it...
Any help would be appreciated.
<p:inputText id="grossPayment"
styleClass="greyText boldText"
converterMessage="#{nts['grossPaymentNumbers']}"
requiredMessage="#{nts['grossPaymentRequired']}"
required="#{bean.profile.salary.required}"
value="#{bean.profile.salary.amount}">
<f:validator
disabled="#{!bean.profile.salary.required}"
validatorId="positiveNumberValidator" />
</p:inputText>

Double JSF only without comma or dot

how is it possible to display a double like "1"
At the moment the double appears with 1.0
But I want to have for example 1,5, too.
But if I have only 1 (the numbers after the comma or dot is zero, than I want to have a value without comma or dot)
How can I do this?
Thanks
I suppose this is what you want to achieve:
<h:outputText value="1,0">
<f:convertNumber minFractionDigits="0" />
</h:outputText>
Will output 1
<h:outputText value="1,5">
<f:convertNumber minFractionDigits="0" />
</h:outputText>
Will output 1,5
Make sure to use correct decimal separator depending on your Locale when testing this.
You can play arround a bit more with the f:convertNumber tag. http://www.jsftoolbox.com/documentation/help/12-TagReference/core/f_convertNumber.html

Display amount in format $###,###,###.## using f:convertNumber

I would like to display the amount in $12,050,999.00 format.
I tried as follows:
<h:outputText value="#{sampleBean.Amount}">
<f:convertNumber pattern="###,###" currencySymbol="$" type="currency"/>
</h:outputText>
However, it didn't display the amount in the desired format. I got 12,050,999 instead.
The desired format is shown in the below image:
How can I achieve this?
Your pattern is wrong for a currency. You should be using pattern="¤#,##0.00".
<f:convertNumber pattern="¤#,##0.00" currencySymbol="$" />
However, there's more at matter: in your original code you also specified the type attribute, which is correct, but this is mutually exclusive with the pattern attribute whereby the pattern attribute gets precedence.
You should actually be omitting the pattern attribute and stick to the type attribute.
<f:convertNumber type="currency" currencySymbol="$" />
Note that this uses the locale as available by UIViewRoot#getLocale() which is expected to be an English/US based locale in order to get the right final format for the USD currency. You'd like to explicitly specify it in either the <f:view>:
<f:view locale="en_US">
or in the locale attribute of the <f:convertNumber>:
<f:convertNumber type="currency" currencySymbol="$" locale="en_US" />

Formatting a double in JSF

I have a problem similar to the one found here : JSF selectItem label formatting.
What I want to do is to accept a double as a value for my and display it with two decimals. Can this be done in an easy way?
I've tried using but that seems to be applied on the value from the inputText that is sent to the server and not on the initial value in the input field.
My code so far:
<h:inputText id="december" value="#{budgetMB.december}" onchange="setDirty()" styleClass="StandardBlack">
<f:convertNumber maxFractionDigits="2" groupingUsed="false" />
</h:inputText>
EDIT: The above code actually works. I was fooled by JDeveloper that didn't update the jsp page even when I did a explicit rebuild of my project and restarted the embedded OC4J server. However, after a reboot of my computer everything was fine.
If I'm not misunderstanding your requirement, I was able to achieve formatting of the value in the input box during the rendering of the view with:
<h:inputText id="text1" value="#{...}">
<f:convertNumber pattern="#,###,##0.00"/>
</h:inputText>
I was using the Standard Faces Components in my vendor-branded Eclipse so I'm assuming the pattern attribute is part of standard JSF.
If what you are trying to do is make the value of the input text field change on screen (to correct user input), you should probably look into using one of the JSF ajax frameworks like Rich Faces.
A possible example would look like this:
<h:inputText id="december" value="#{budgetMB.december}" styleClass="StandardBlack">
<f:convertNumber maxFractionDigits="2" groupingUsed="false" />
<a4j:support event="onblur" reRender="december" />
</h:inputText>
I haven't tested this, but I think it may work.
It seems you're actually formatting a currency. There already exists a specific formatter to handle currencies that you can assign many options to:
<f:convertNumber type="currency" />
Some interesting attributes of this tag are: locale, currencyCode, integerOnly, currencySymbol and pattern.
