is there a possibilty in camel to overwrite the default delay value for file processing?
http://camel.apache.org/file2.html => the default deleay is set to 500ms. So camel polls everey 500ms a directory. I want set this value different for all my routes globaly, and not overwrite on each route manually ... any suggestion?
Thanks
No you cannot set it globally. But it can be a nice idea, so you are welcome to log a JIRA ticket

I am trying to reset a filepond field to a default image on user action (ie: clicking on a button).
The file could be local or uploaded somewhere (as AWS) it does not matter.
I currently load a default image when the webpage (and therefore the filepond instance / element) is first loaded, so I guess manually calling the load method would do the trick but I can't manage to do that.
I also try with the file-poster plugin, but there is no way to reset the image after it has been deleted.
If you have found a way of doing this or are thinking about something, please let me know :)
Actually #Rik was right, just use addFile function with the option type: "local".
I have a camel route that splits and aggregates according to some ids. When an id is retrieved, a call is made to another endpoint to retrieve the project information according to this id. After retrieving the project information i had to enrich it by calling multiple enrich() methods on it. In the first enrich method i have to do some xpath processing wherein ill be able to retrieve a primaryOrgId value that i will set as a property in the exchange, dont worry about the xpath processing, i had that sorted out but my problem is when I set the property (primaryOrgId) inside the 1st enrich. The property value doesn't get persisted when the route goes to the 2nd enrich part. When I log the primaryOrgId value, the original value of "testValue" (this was set in the direct:createSomeIds route) is the one getting displayed instead of "changeTheValueHere" which was set in the 1st enrich part.
I am using Camel 2.15 based on Fuse 6.2.1.
I went to the camel site and read this part from http://camel.apache.org/content-enricher.html . I'm not sure I understood how to implement... "For that you must set the filename in the
endpoint URI" .. this text was talking about the header, i'm thinking its also applicable to the properties in the exchange.
pollEnrich or enrich does not access any data from the current
Exchange which means when polling it cannot use any of the existing
headers you may have set on the Exchange. For example you cannot set a
filename in the Exchange.FILE_NAME header and use pollEnrich to
consume only that file. For that you must set the filename in the
endpoint URI.
Here is my code:
from("direct:createSomeIds")
.routeId("createSomeIds")
.process(new IdCreatorProcessor()
.setProperty("primaryOrgId").constant("testValue")
.split(xpath("/TempProjects/TempProject/Code/text()").namespaces(ns) , new IdStrategy())
.to("direct:splitRouteById")
.end();
from("direct:splitRouteById")
.routeId("splitRouteById")
.to("direct:getProjectByID")
.to("xquery:template/AllProjectToSingleProject.xq") //xquery template
.convertBodyTo(Project.class)
.enrich("direct:getAdditionalInfo", new ProjectStrategy(ProjectStrategy.AggregatorType.AdditionalInfo))
.enrich("direct:getSecondaryInfo", new ProjectStrategy(ProjectStrategy.AggregatorType.SecondaryInfo))
.end();
from("direct:getAdditionalInfo")
//some xpath stuff here
.setProperty("primaryOrgId").constant("changeTheValueHere")
.end();
from("direct:getSecondaryInfo")
.log("Value of primaryOrgId = " + "${exchangeProperty.primaryOrgId}")
.end();
If you can provide some code example, that would be helpful.
If you read a bit further down you will see that it's recommended that you instead use RecipientList with an AggregationStrategy.
.recipientList("direct:getAdditionalInfo", "direct:getSecondaryInfo")
.aggregationStrategy(new ProjectStrategy())
The setting of filename in your endpoint URI would only be applicable if you were to access some file on an FTP or some other file area.
Edit:
I now see that you need the property from the first enrichment in your second enrichment. However, if you're not modifying the message body in the first enrich then I don't actually see the need for it at all.
If you are in fact modifying the body then you can still use the RecipientList but instead you use two separate ones calling only one endpoint in each.
How can I get a trigger once my route completes processing a directory and its sub directories in camel ? Is there any way I can specify this in the route ?
Yes if its from("file:..") then its a batch consumer, and you can find the information on the last file which has a message header with CamelBatchComplete with the value true.
See more details at the Camel website: http://camel.apache.org/batch-consumer.html
I'm using Solr 6.5 to index files from multiples ftp files into multiples cores (having one core for each type of document, like audio file, image, software, video and documents).
The situation is that I'm doing this to populate an app that in its front end has a social networking approach in which every user can add new tags or modify other metadata without restriction.
So when I execute again data import handler to add new files to my application, it erase the index that previosly was modified for the user and set up with the data-config default configuration.
My question: is there a way to tell DIH, if the id exists, continues without importing and just adds the files which don't have an id in the index?
If this is not possible, can I do something similar in a different way?
Thanks for everything!
Sounds like you are doing a full import with default settings. One of them is clean, which defaults to true and deletes the whole index before the import.
Try setting it to false and also look at preImportDeleteQuery and postImportDeleteQuery for even more precision.
Iam trying to automate the testing of a java bundle,Which will process once a file is dropped in a particular folder.
can we drop a file to a folder location automatically using camel,or at a set period of time(not intervals)?
is this possible purely by camel or should we incorporate other frameworks?
sure, you can use the camel-file component to produce (create files somewhere) and consume (read/process files from somewhere) and optionally control the initial/polling delays easily with attributes...
here is a simple example of consuming->processing->producing
from("file://inputdir").process(<dosomething>).to("file://outputdir")
alternatively, you could periodically produce a file and drop it somewhere
from("timer://foo?fixedRate=true&period=60000").process(<createFileContent>").to("file://inputdir");
Although camel could do this by creating a timer endpoint, then setting the file content and writing to a file endpoint, my answer would be to simply use a bash script. No camel needed here.
Pseudo bash script:
while [ true ]
do
cp filefrom fileto
pauze 10s
done
