Multiplying values compilation error

Anonymous — Fri, 18 Sep 2015 18:31:52 GMT

Hi all,
I am trying to convert a csv file to xml. I have a csv and an xml created using an existing format in my meta data.
I have an input file, a tmap, and an output file.
In the tmap, i'm trying to map a decimal column to an integer column, while multiplying the value by 100 in the process.
I googled a few methods, and the one below seemed to be used by others.

row1.Price.Multiply(BigDecimal.valueOf(100))

However, Multiply gets underlined, and an exception of Unresolved compilation problem is generated.
I read somewhere else about looking for the error in the code, but I can't even find "multiply" in the code, so i'm assuming i've not installed something correctly, but it might just be that i'm using the wrong statement in the first place.
Any pointers in the right direction would be much appreciated.

Kind regards
Phil

Hi Phil,

Have you tried to switched tab from "Designer" to " Code" to see unresolved compilationin java code?

Do you check component TalendHelpCenter:tWriteXMLFields which embeds the incoming data into a single XML column.

Hi Sabrina,

How do I do that?
I have a repository tab on the left, with Business Models, Job Designs (with my job in it), Contexts, Code etc.
In the Code section is Routines and Pig UDF.
In the Routines section is System, and under that; DataOperation, Mathematical, Numberic, Relational, StringHandling, TalendDataGenerator, TalendDate and TalendString.

Kind regards,
Phil

Hi Phil,

Next to the Designer tab there is a Code tab that lets you view the source code for the entire Job.

Thanks Sabrina,

Is it correct that I shouldn't actually see any code? However, I can see the warnings and errors.

Other than the "The method Multiply(BigDecimal) is undefined for the type BigDecimal" in the screenshot, the warnings include (in order, and the first 2 warning markers in the screenshot are for the same warning);
Comparable is a raw type. References to generic type Comparable <T> should be parameterized.
Type safety: The method compareTo(Object) belongs to the raw type Comparable.
Type safety: Unchecked cast from List to List
Type safety: The method add(int, Object) belongs to the raw type list.
The method getRowNumber() from the type FileInputDelimited is deprecated.
The static method convertToJsonText(Object, List<string>) from the type ResumeUtil should be accessed in a static way.

However, I might have found the reason why i'm getting these errors, but I don't know how to resolve it:
On opening Talend, the Additional Talend Packages installer starts and show available features to install:
1 optional and 338 required. Version 6.0.1.20150908_1633.

However, they fail to install;
java.net.SocketTimeoutException: Read timed out
at java.net.SocketInputStream.socketRead0(Native Method)
at java.net.SocketInputStream.read(Unknown Source)
Any pointers in the right direction would be much appreciated.

Kind regards,
Phil

Have you tried to restart your studio to see if it works?

Is your network OK with you? Here is a document about:TalendHelpCenter:Configuring Talend Studio.
