I am trying to build the name of a var dynamically by concatenating the value of a variable and adding some string afterwards, as I add these variable in runtime. Something like the following should work but it does not.
th:text="${__#{myClass.getA().getB()}+'-result'__}"
Is this even possible to do? I dont know the name of the variable, I can only construct it like this unfortunately.
Yes, that is possible, Thymeleaf supports expression preprocessing:
Let's start with some examples:
The message(i18n) expressions should be referenced using the # character. So let's suppose you have the message.key in your translation file. To reference it in Thymeleaf you will have to use
th:text="#{message.key}"
In your scenario your key name is generated dynamically based on a variable so for preprocessing it in thymeleaf you need to use two underscores __
Let's suppose in your context you have a model variable called myModelVariable with a method messagePrefix(). Our example becomes:
th:text="#{__${myModelVariable.messagePrefix()}__}"
This means the myModelVariable.messagePrefix() will be processed first and the result will be used as the key name which will be then resolved to a nice user friendly message.
And if you also want to add a static part at the end of it will look like this:
th:text="#{__${myModelVariable.messagePrefix()}__}+'*'"
Even the key can contain a static part so this is also accepted:
th:text="#{__${myModelVariable.messagePrefix()}__.staticsuffix}+'*'"
More info you can find in the section 2.7 here:

I have a lot of repeating texts inside of my SAPUI5-App. Hence I have the same value with different keys in i18n.
I don't want to merge them into one key because of readability.
one example:
PROFILE_CHAPTER_A=Details
GREET_MESSAGE=Greetings
[...]
WIZARDSTEP_A=Something
WIZARDSTEP_B=Different
WIZARDSTEP_C=In
WIZARDSTEP_D=These
WIZARDSTEP_E=Ones
WIZARDSTEP_F=Details
[...]
#I wish for something like this
GREETING_FORUM={GREET_MESSAGE} {0}, Hello in our Forum!
GREETING_ WEBSOP={GREET_MESSAGE} {0}, Welcome to our Webshop!
You see that PROFILE_CHAPTER_A and WIZARDSTEP_F have the sam value.
In this case I don't want to reference to only one of them because if I'm inside of the view I want a clear naming of the i18n. But if I mean the exact same thing I want to change it only once and not in 5 different keys.
An example of what I imagine should be possible. Maybe I just want to change the "Greetings" to "What's up" or something else and then I just want to reference the first word and have it used by everything else.
Is this i18n-nesting possible in (SAP)UI5? And if not, can it be added?
We use the namespace concept for i18n files:
# Global used
core.detail = Detail
core.button.ok = Ok
# Assuming there is a view with namespace: my.great.app.detail
detail.title = title
# Assuming there are dialog in my.great.app.detail
detail.dialog.confirm.title = Done, saving?
detail.dialog.delete.message = Really?
# another (sub) view: my.great.app.detail.specialParts
detail.specialParts.title = very special
Works also flawless for multi component apps, if you prefix component name.
So I'm trying to create another .property file (called labels.properties) that i can use in Thymeleaf like this:
<div th:text=#{property.from.labels}></div>
Right now I just add labels.properties in the root of resource folder, for now its not working. The purpose of this is I want to separate the property file that handles the error messages from texts for labels & buttons.
Is that possible?
if yes, how to do it?
if yes again, can I do internationalization like adding labels_ja.properties (Japanese)?
You can customize the naming (and location) of the message bundles by configuring the spring.messages.basename property. For example:
spring.messages.basename=labels
By doing so, Spring will look for messages within classpath:labels.properties and classpath:labels_{locale}.properties, such as classpath:labels_ja.properties.
If you want to use this in addition to the regular messages.properties, you can use a comma separated value:
spring.messages.basename=messages,labels
The first one within that comma separated list will take priority over the other ones. If you have a property.from.labels in both messages.properties and labels.properties, the one within messages.properties would be chosen in this example.
This can also be found within the documentation about internationalization.
I was using netflix's nebula. Looking here, I saw this line:
fileType [org.freecompany.redline.payload.Directive] - Default for types, e.g. CONFIG, DOC, NOREPLACE, LICENSE
I didn't find any doc about the actual meaning of this enum, but I've found the original code.
Now I want an actual description of this enum. I thought NOREPLACE is releated to being not allowed to replace the file. But I want to be sure and don't rely on assumptions.
I have only seen noreplace as an additional attribute on a config file, e.g. %config(noreplace). It means that if the user has edited the file, the installer should put its new version as filename.rpmnew; by default %config files are replaced with the user one put as filename.rpmold .
I'm using the environment variable $PMTargetName#numAffectedRow, but the TargetName is a parameter(parfile)
I'm trying to do this way:
$PM$$SOURCE_TABLE#NumAffectedRows
Is not working :/
What you need to use here is the name of the Target Transformation, not the table name. So assuming you've got a Target Transformation named MyTargetTable and you use the Target Table Name property to set the actual table name to e.g. Customers, then:
$PMMyTargetTable#TableName should give you Customers
and $PMMyTargetTable#NumAffectedRows should get you what you're looking for
The variables to be used in pre/post session commands need to be passed to the session from parameter file. e.g. $PMTargetName should be used in your session e.g. as Target Table Name. If you are doing this, then this will work - ${PMTargetName}#numAffectedRow. Adding parentheses will ensure your variable is expanded before #numAffectedRow is appended to it.
If you are not using $PMTargetName anywhere in your session then IS will not expand it. You should declare it as your workflow variable. And since you have already defined it in parameter file...rest should work.
I have my tag ${file.name} in a jsp file to display a name of file to download
name containt a full file name,include file extension. for example
testfile.png
a-file.zip
testfile-test505454654.png
a-filenum5468.docx
other_file_with_a_name_very_very_very_larrrrrrrrrrrrrrrrrrrrrge.pdf
Files with very long names, crash my layout.
I think the way to format the file name to shorten it but include the extention. Maybe
testfile.png
a-file.zip
testfile-test505454....png *
a-filenum5468.docx
other_file_with_a_na....pdf *
How I can do?
in href no problem because it is done by id ${file.id}
If file is a POJO, you may add a getter-method to the POJO (something like String getShortName(){}) that returns a short version of the file name. And then use the method in your EL expression: ${file.shortName}.
I would write and register a custom tag that would take care of shortening the output to a maximum length
<custom:short value="${file.name}" var="shortFileName" />
The tag would take care of shortening based on defaults or values you specify in the element and putting it the result in a request attribute you can use anywhere after that declaration.
Since the requirements can be used many times so You should go with CUSTOM Tag solution like #Sotirios Delimanolis suggested.
JSTL function ( Like c:fn ) is another solution. Using jstl function get better performance than Custom tag ( simple / classic model )
