QUESTION
I have a issue with camel apache. My csv file has LF and CRLF in it. The LF is present in the values of my csv file. When camel gets my file from the ftp and put it on my desktop, the LF is no more there. But i need the LF character to format correctly my csv and cosume it with the bindy component.

QUESTION
I'm trying to use Apache Camel (version 2.25.3) reactive streams in combination with Spring Boot to read a large csv file and unmarshal the lines using Bindy. This is "working" in the sense that the application runs and detects files as they appear but I then only see the first line of the file in my stream. It appears to be Bindy related because if I take the unmarshalling out of the equation I get back all the lines of the csv file in my stream just fine. I have simplified the problem to demonstrate here on SO. I'm using Spring Webflux to expose the resulting Publisher.
So my Camel route is as follows:
...ANSWER
Answered 2021-Jan-06 at 06:43I guess that the file consumer just pass the whole file to the unmarshalling step.
Therefore if you unmarshal the result of the file consumer to a LineItem, you "reduce" the whole file content to the first line.
If you in contrast remove the unmarshalling you get the whole file content. But probably the file consumer loaded the whole file into memory before passing it on.
But reading the whole file is not what you want. To read the CSV file line by line you need to split the file in streaming mode.
QUESTION
Usecase: We generate a csv file when user hits an endpoint, which we want to upload to different sources (FTP & S3). We need to encrypt & transform the files before uploading. Here's how the routes look like (oversimplified):
FTP Route:
...ANSWER
Answered 2020-Oct-02 at 10:26I managed to get it working by using a static route id (Removed LocalDateTime.now()). Here's what I learnt while fixing Camel issues.
- Always provide route ids to every route. Especially while using 'direct' routes.
- Never use dynamic route id. This is very important. I was seeing this issue when I had used
LocalDateTime.now()in my route id. I was seeing this error before I changed:
Multiple consumers for the same endpoint is not allowed: direct://routeName .....
- When using loops or calling any direct routes, always use enrich.
eg. .enrich("direct:subroute", AggregationStrategies.useOriginal()).
This will share a copy of parent route's headers to the subroute. It'll help you to avoid some weird issues.
Feel free to comment in case if you'd like to know more.

I'm trying to unmarshal a csv file using Camel Bindy. The csv file has ; as separator, the issue is that for empty values it contains a . character. So for example:

I try to use camel with cron expressions. Because i need 3 different things to do with cron expressions, 3 different timings. Daily, monthly and instant check of files in remote. I can not do it with spring batch. So, i chose camel.

Answered 2020-Jun-26 at 07:39From Camel Doc for Cron Components, you have to inject dependency camel-cron before use.

My aim is to read a CSV file, convert it to JSON and send the generated JSON one by one to ActiveMQ queue. My Code below:
...ANSWER
Answered 2020-Mar-25 at 10:52If nothing happens at all when starting the route then it is most likely due to the relative path you passed to the file component. Probably the execution directory of your Java process is not where you think it is and the file is not found. To simplify things I suggest you start with an absolute path. Once everything else is working figure out the correct relative path (your base should be the value of the user.dir system property).
Re your question about splitting the contents: This is answered in the documentation.
This works for me (Camel 3.1):
QUESTION
Getting following exception in Camel:
...ANSWER
Answered 2020-Feb-20 at 20:07This can be overcome by applying the following code on your POJO class. This is basically telling Bindy to ignore characters that comes after the last mapped fixed length data as per POJO.
@FixedLengthRecord(ignoreTrailingChars = true)
You can perhaps open your file in notepad++ after enabling View -> Show Symbol ->Show All Characters and see if any characters are actually present at the end. These characters are commonly noticed when dealing with files generated from a different OS. You can also doublecheck the mapping to ensure that all the fields are actually mapped as per the correct length, which can go easily unnoticed.
QUESTION
A test file with delimited Data and one of the field is amount and it arrives as a string. To be converted to float. As per camel-bindy i tried a way, but ended with same value without precesions. Input : 12345678
@DataField(name="AMT", trim=true, pos = 15 , precision=2) private BigDecimal amount;
Route: .unmarshal().bindy(BindyType.Csv, Test.class)
O/P: 12345678.00
Its not getting converted to 123456.78
Please help me with any suggestions.
...ANSWER
Answered 2020-Jan-06 at 11:33Annotation @DataField provides another method implementation which supports this kind of feature,
@DataField(name="AMT", trim=true, pos = 15 , precision=2, impliedDecimalSeparator = true) private BigDecimal amount;
impliedDecimalSeparator decides the decimal position for incoming string field and converts as required.

QUESTION
The goal is to produce a report every hour by comparing two CSV files with use of Camel 3.0.0. One is located on a FTP server, the other on disk. How to use poll enrich pattern in combination with unmarshalling the CSV on disk with Bindy Dataformat?
Example code (for simplicity the FTP endpoint is replaced by a file endpoint):
...ANSWER
Answered 2020-Jan-05 at 23:17You can wrap enrichment with direct endpoint and do unmarshaling there.
