I am trying to condtionally create a component using #ConditionalOnExpression("not ${service.synchronous} && not ${service.disabled}").
I based this on Spring Boot SpEL ConditionalOnExpression check multiple properties, which provides a multi-property conditional as follows: #ConditionalOnExpression("${properties.first.property.enable:true} && ${properties.second.property.startServer:false}")
However, I keep getting:
Caused by: org.springframework.expression.spel.SpelParseException: EL1041E: After parsing a valid expression, there is still more data in the expression: 'lcurly({)'
Those properties are always set in my .properties file so I did not provide a default value with the colon notation. What am I doing wrong?
You will need to provide the default values for your properties like in the example you followed, so update the expression to be:
#ConditionalOnExpression("not ${service.synchronous:false} && not ${service.disabled:true}")
In most such cases the properties your app is reading are not what you expect them to be.
Set a breakpoint on all constructors of SpelParseException. In the debugger you will see the expression that is parsed, that will give show you exactly which properties you are really using.
Maybe you have to go search a little in the stack until you find the right location where you can see the expression.
My mistake was that I had not imported the test properties file in a Spring test.
After I added #TestPropertySource("classpath:/application.properties") to the test class, the properties from the properties file were used.

I want to keep date format to fix standard regardless of locale. But however it is by default taking current locale and setting format based on locale.
th:text="${#dates.format(myDate, 'dd-MMM-yyyy')}"
I am always expecting format be like
09-Sep-2015
but with CA locale I am getting 09-de set.-2015
Is there a way to fix this.
UPDATE
This question is not duplicate of This question. My problem is related to locale formatting.
Not sure you are using Maven or Gradle. Add thymeleaf-extras-java8time as your dependency.
and instead of #dates use #temporal and specify locale as parameters as below.
th:text="${#temporals.format(myDate, 'dd-MMM-yyyy','en')}"
But make sure your myDate is in java.time.* format
The #temporals.format function is the correct one to use. However, the third "locale" argument must be a java.util.Locale object, not a string.
The following work:
#temporals.format(myDate, 'dd-MM-yyyy', new java.util.Locale('en'))
#temporals.format(myDate, 'dd-MM-yyyy', #java.util.Locale#ENGLISH)
Note that this is true even if you're working with Kotlin Spring Boot. The syntax in the Thymeleaf template isn't Java, it's an OGNL Expression.
https://commons.apache.org/proper/commons-ognl/language-guide.html
I'll quote the useful syntax used here:
#variable
Context variable reference
#class#method(args)
Static method reference
#class#field
Static field reference
new class(args)
Constructor call
Edit: one other option is to specify the Locale in the Thymeleaf context, if you just want to override the default system Locale. I've included a Kotlin snippet of how that might work:
val context = Context() // org.thymeleaf.Context
context.locale = Locale.ENGLISH
context.setVariable("x", 0)
templateEngine.process("classpath:template.html", context)
I am trying to add expression validation on my property on actionbean but I am unable to make it work. I have even tried with integers like this >0 but still the same exception is thrown. Below is the code
#Validate(required=true, minvalue=1, expression="${this > maxBudget}")
int minBudget;
int maxBudget;
I am getting the below exception:
net.sourceforge.stripes.exception.StripesRuntimeException: Could not parse the EL expression being used to validate
field minBudget. This is not a transient error. Please double check the following expression for errors: ${this > maxBudget}
caused by
javax.el.ELException: The identifier [this] is not a valid Java identifier as required by section 1.19 of the EL specification (Identifier ::= Java language identifier).
This check can be disabled by setting the system property org.apache.el.parser.SKIP_IDENTIFIER_CHECK to true.
I have tried few variation, but every time it throws this exception.
Can some one please point out the mistake I am doing here
thanks
If you want to make sure minBudget is larger than maxBudget (isn't that the other way around?) you could just do:
#Validate(required=true, minvalue=1, expression="${minBudget > maxBudget}")
For greater flexibility you could consider implementing a custom validation method:
#ValidationMethod(on={"show"})
public void checkBudgetRange(ValidationErrors errors) {
if (minBudget < maxBudget)
errors.addGlobalError( new SimpleError("This is not good..."));
// all sorts of other checks to your liking
}
The on array argument holds the name(s) of the event handler(s) for which you want to perform this validation method. So in the example here that would be public Resolution show().
There's an excellent explanation at the Stripes Framework site at https://stripesframework.atlassian.net/wiki/display/STRIPES/Validation+Reference
UPDATE:
If you want to make use of the this keyword in validation expressions you may need to add a VM argument to your server (tested this on Tomcat 8):
-Dorg.apache.el.parser.SKIP_IDENTIFIER_CHECK=true
Otherwise the abovementioned error may be thrown.
The default value of org.apache.el.parser.SKIP_IDENTIFIER_CHECK was changed from true to false as of version 7 in Tomcat.

I am writing a Grails (2.3.3 currently) application and have created a validateable command object similar to the following:
#Validateable
class MyCustomCommand {
String name
static constraints = {
name blank: false
}
}
In my i18n/messages.properties file I defined the following properties to override the default error messages.
MyCustomCommand.name.blank=Name must be provided.
MyCustomCommand.name.null=Name must be provided.
Which per the Grails documentation should be of the format [Class Name].[Property Name].[Constraint Code] as I have done. When I run my application if I leave the value blank I still get the default message for a null property.
I also tried following the example of the default messages and defining them a follows, but still get the default message.
MyCustomCommand.name.blank.message=Name must be provided.
MyCustomCommand.name.null.message=Name must be provided.
I am assuming that I am missing something simple here, but have yet to stumble upon what. Any suggestions on what I am doing incorrectly?
It is simple indeed. Message should look like:
myCustomCommand.name.blank=Name must be provided.
myCustomCommand.name.nullable=Name must be provided.
//className.propertyName.blank (camelCase with first letter of class name lower)
So, as I anticipated it was something simple. I was using the defaults as an example which used null where as what I really needed was nullable. Which does make sense as that matches the constraint name.
Therefore the correct version is:
myCustomCommand.name.blank=Name must be provided.
myCustomCommand.name.nullable=Name must be provided.
Problem:
Attempting to use the JYTHON command below and I cannot retrieve the id of my active specification defined at a node-server level in Websphere. I believe its a syntax issue but I'm not sure what.
Code:
AdminConfig.getid('/Cell:mycell/Node:mynode/Server:myserver/J2CActivationSpec:myActiveSpecName/')
Problem Notes:
I do not get a invalid object error so I believe I have the syntax right but it just cannot find the resource even though it exists.
I am using the AdminConfig.getid() as a way to check if the resource already exists in order to do a modify or a create.
If I use the following code: AdminConfig.getid('/J2CActivationSpec:myActiveSpecName/') it will find it but not if I use a more specific path listed above.
Reference Material:
IBM Documentation
Containment paths are always a little tricky. In my (limited) experience, even if you can trace the path by AdminConfig.parents, you may not always be able to use getid.
Are you restricted to using getid? If not, here are some alternatives that will get you an ActivationSpec at the /Cell/Node/Server level:
Querying using AdminConfig.list
This approach will list the Activation Specifications at the specified scope (in our case, the server), and grab the one that has it's name attribute equal to 'myActiveSpecName'.
server = AdminConfig.getid('/Cell:mycell/Node:mynode/Server:myserver')
activationSpec = ''
for as in AdminConfig.list('J2CActivationSpec', server).splitlines():
if AdminConfig.showAttribute(as, 'name') == 'myActiveSpecName'
activationSpec = as
print 'found it :)'
Using Wildcards
This approah uses AdminConfig.list as well, but with a pattern to narrow down your list. If you know your activation spec's configuration begins with myActiveSpecName, then you can do the following:
activationSpec = AdminConfig.list('J2CActivationSpec', 'myActiveSpecName*')
I'm having trouble getting the while controller to work in jmeter.
I've a feeling that I read that it doesn't re-evalute user defined variables, so I am trying to use properties instead.
I start off by using a BSF assertion to set a property called keepLooping
${__setProperty(keepLooping, true)};
This seems to work as it enters the While controller with a condition of
${__property(keepLooping)}
But I cannot for the life of me get it to change that property to something else. I want it to change the property depending on the resulting text of an http request.
So I am using a Regular Expression Extractor to set a variable, which I can see is getting set. Then I am trying to use a BSF assertion to set the keepLooping property on the basis of the variable that I have set. I am using javascript as follows:
log.info("IM IN HERE");
log.info("props is "+props);
//log.info("props keep looping is "+props["keepLooping"]);
if (${surveyRequired} == false){
log.info("IM IN HERE 1A and props is "+props);
${__setProperty(keepLooping, true)};
log.info("IM IN HERE 1B");
}
else {
log.info("IM IN HERE 2A");
${__setProperty(keepLooping, false)};
log.info("IM IN HERE 2B");
}
I can't figure out how to set the property with javascript - I've tried several things. Can anyone help? Many thanks!
Also can anyone recommend a good resource that negotiates what seem to be the many 'quirks' of jmeter? Many thanks!
"I've a feeling that I read that it doesn't re-evalute user defined variables" -- I use JMeter 2.9 and it really does. I use user defined variable in order to count number of loops. It looks like: ${__javaScript(${MY_USER_DEFINED_VARIABLE}>0)}. The only one annoying thing is that I have to get value of variable, increment it, cast to string (toString() in Groovy), and then put new value into MY_USER_DEFINED_VARIABLE (by using vars.putObject("MY_USER_DEFINED_VARIABLE",localBSFVariable))
Using vars.put or props.put will help, as explained in detailed in detail in this jmeter thread.
