A typical issue when working with files in Java is a FileNotFoundException during program compilation, even though the program has not yet tried to find the file. You may see some of the following symptoms:
Or the following, as seen in the Eclipse Development Environment:
The reason for these errors is that you need to handle the possible exception, in case a value is passed into the constructor for FileInputStream that is not a valid file. A good way to handle this exception is by adding a throw condition on the function declaration as seen below:
Another way, and probably the best way to handle this is to add a catch to your try statement. Then, you can handle the exception with any follow up logic that is needed and allow the function to handle it internally instead of throwing the exception.
There is a bug in Talend Open Studio for Data Integration version 5.0.2 when trying to connect to SQL Server without passing a user name and password. Java requires libraries for single signon for this to occur, specifically the ntlmauth.dll file for the system. However, in Talend Open Studio 5.0.2, having this file does not allow single sign on to Microsoft SQL Server. This is confirmed on Microsoft SQL Server 2008 R2 64-bit.
When attempting to connect without supplying a username and password, the following error is received:
This issue is fixed in production release 5.1.1 of Talend Open Studio. A workaround in version 5.0.2 is not available at this time.
There is a bug in Talend Open Studio for Data Integration version 5.1.1 when adding a database connection. It has to do with the jdts component used for Microsoft SQL Server connections. When adding a new connection you may get one of the following errors:
The above error usually appears the first time you hit the button to “Check” the connection. The second and subsequent attempts will produce a different error message as follows:
This is a bug in Talend Open Studio for Data Integration that has a fix already implemented in the future 5.1.2 version.
There are a lot of web programming languages available. It’s often dificult to choose one, but among web programming one sticks out beyond all the others. It is PHP (originally and acronym for “Personal Home Page”).
The reasons that PHP make a great language to learn include the following:
It runs on web servers that are free to install and run
The web servers available run on many different operating systems
It is very powerful, like many web programming languages
There are great, free development environments available
PHP is the backbone to many popular content systems, including WordPress Blogging
Why choose web languages that requires expensive development environments and high licensing costs? Put your time into learning a language that is free to develop and run, comes with no licensing headaches, and is still powerful.
