Hello, I would be good to be able to drag & drop a file in Talend Data Preparation to open it.

tXMLMap: Use of a variable to Rename a Tree Node - by rhall_2.0
The easiest way to do this is to produce the XML in the tXMLMap, convert it to a String using the tConvertType, do a find and replace using Java String methods, convert the resulting String back into an XML Document using the tConvertType. Yes it sounds cumbersome, but is actually really easy to implement and fills the gap you have spotted here.

cMessagingEndpoint and RabbitMQ (ESB Mediation) - by ORo
Dear all, I'd like to read messages from RabbitMQ. For that I've done the following: [list=1] [*]I created a new route[/*] [*]I added a cMessagingEndpoint on the "job" with "rabbitmq" in Advanced Settings and the following URI:ÃÂ "rabbitmq://127.0.0.1:5672/myExchangeName?queue=myQueue"[/*] [*]with the assumption to read messages I added cLog as well and added a route from cMessagingEndpoint to cLog[/*] [*]I started the job[/*] [*]on RabbitMQ Management Console I inserted a new message to the respective exchange "myExchangeName" and the message ended in the queue "myQueue"[/*] [/list] The problem. Nothing happens. The message is still in the queue. cLog doesn't show anything. What did I do wrong? Kind regards, ORo

tXMLMap not supporting some XPath expressions? - by rhall_2.0
You have to understand that XML is a hierarchical data structure which can be loosely equated to a small set of related RDBMS tables. As such, you can get multiple flattened rows from a single file. You might want to restrict the "rows" that get to the output using the variables or the output filter that I mentioned previously. But if you simply want to get the value of an element based on its attribute value, this can be done by using the attribute and the element with a tXMLMap variable.ÃÂ I sense that you are probably a Java developer that is new to Talend. If this is the case, at first Talend can seem a bit counter intuitive. However, there is method in what first appears to be madness. The biggest mistake made by people who know Java and are new to Talend is "recreating the wheel". Using Talend to trigger bespoke Java code. There is nothing wrong with writing your own code and making use of third party APIs (that is one of the things that makes Talend great in my eyes), just be careful not to "recreate the wheel". Good luck.

File size - by brian_indy
I am trying to run some CSV data through the tool and it keeps crashing at the end of the adding dataset process. ÃÂ The file itself is about 2.8GB, which is what I may end up dealing with if I pull from an HDFS datastore. ÃÂ Is there a maximum file size that the tool can ingest and is there a way to tune the Java stack?

Oracle db copy - by jlolling
Hi, I am sorry but I guess this will not work because dealing with Oracle BLOBs is a bit more complex than what the component provides. I will check if I can this capability.

Difference between Standard jobs and Big Data jobs in Talend - by jholman
ÃÂ ÃÂ ÃÂ The images you provided appear identical (both labeled Standard Job) so I'm not entirely sure of the differences, so I will summarize the current type of jobs as of 6.1.1 as I understand them: 1. Standard - This is just a java process. It can access many data sources via JDBC or HDFS,etc but the main process just executes in a JVM.ÃÂ 2. BigData Streaming - This is for realtime-ish/microbatch stuff, the jobs are sent to Spark or Storm for execution.ÃÂ 3. BigData Batch - Uses either MR1(namenode,etc)/YARN for MapReduce execution, or Spark for execution (With or without YARN depending on platform) Hope that helps! P.S. Imapla is it's own thing, so I would expect that part to behave about the same if on the same hardware.ÃÂ

Connect to Impala with LDAP authentication - by jholman
It should be fairly trivial to edit the tImapalaConnection template (look in ${TALEND_HOME}/plugins/org.talend.designer.components.bigdata_${VERSION}/components) and add an additional dropdown "AuthMec" to the component and remove the 'noSasl' string. See if you can find a tutorial likeÃÂ http://www.talendforge.org/wiki/doku.php?id=doc:component_creation_example_java to show you how to edit a component.ÃÂ

How to export a Job from Talend Studio in XML format? - by jholman
I would suggest trying to use a bulkloader that works as long as the source file fits the destination table. This way you can loop over a set of tables and dump them using a dynamic schema to write the files, and then bulk load them even if they have different schemas as long as they fit the target (this depends on what database you are using but for MSSQL "bcp" will work, or "nzload" for Netezza, etc)ÃÂ

Read multiple excel files - by vital_parsley
Hi , Could anyone please let me know how can I design a job where I am reading from multiple excel files and loading it to a database. I could create separate jobs each having its own texcelfileread ----> tMap --> tOracle texcelfileread ----> tMap --> tOracle texcelfileread ----> tMap --> tOracle so on... But I would like to design in the below way or any other efficient way that you can suggest : texcelfileread ----\ texcelfileread ----> tMap --> tOracle texcelfileread ---/ So here I collect all the data from 3 excel files first then apply any transformations any then load it to tOracle component. Kindly let know your suggestions asap.

Transforming three dimensional tabular data to XML - by needtalend
Hi Amol, thanks again for your response. I tried your example, but I am not able to join the "emps" and "printers" child nodes in the tExtractXMLField with the destination "dept" schema in tFileOutputXml (replaced tLogRow_5) as the "emps" and "printers" nodes are grayed out(disabled) in tFileOutputXml. Are the Xpaths you mentioned in tExtractXMLField for "emps" and "printers" are correct? I would think, the "emps" and "printers" nodes in tFileOutputXML and the ones in tExtractXMLField are of the same structure, right? ÃÂ A screenshot of "emps" and "printers" nodes mapping would help me. Thanks again.
