Concatenating Strings in ColdFusion with Java

Oct 24

Posted by Ricardo in ColdFusion, Java

Jason Delmore posted an interesting article comparing string concatenation using ColdFusion and Java.

stringbldr = createObject("java", "java.lang.StringBuilder").init();
for (i=1;i<=iterations;i++) {
stringbldr = stringbldr.append(appendstring);
}

Here the complete article.

Parsing Large XML File Into ColdFusion XML Object

Aug 26

Posted by Ricardo in ColdFusion, Java, XML

Last week I had a big headache trying to import a 165MB XML file. I couldn’t even open it with any browse and reading it with ColdFusion gave me 500 errors, exceeded heap size, JRun closed connection, etc…

The solution I found was to read the file line-by-line using Java and creating blocks of XML code that allowed me to parse into objects and process them individually. Remembering, we use CF7 yet.

So I wrote this piece of code where I set my start tag and it will grab everything between my start and end tag, and assemble a XML object from there. I know the CF Gurus would suggest a much better solution, but that’s what i could accomplish with my humble knowledge and give a quick solution for the problem.

Check If File Is Available (revisited)

May 22

Posted by Ricardo in ColdFusion, Java

In my post Check If File Is Available I showed a code using the Java method canWrite() to check if the file was available to be worked (read/write). Our colleague Marco Antonio commented that it could cause a race condition, so it is not a good idea to use it for that purpose.

Here is a link to a discussion where you can find more information: StockOverflow

Check If File Is Available To Write/Rename/Move Part II

Apr 22

Posted by Ricardo in ColdFusion, Java

I mentioned in my previous post with the same title that I used a renaming function to check if the file was finished and unlocked by the FTP transfer, so I could work with it. Well, after several tests using the renaming test, I was still getting lock up errors and my process was stopping.

After some research, I realized that our FTP server (WS_FTP) did not lock the file when writing to it, so I was able to rename it, and it would continue to upload to the same renamed file. Even when I moved the renamed file to a work directory, the file size was still being increased. So none of my test functions would work.

Instead of changing the FTP server settings – it is an old one installed in 2002 – I decided to install Filezilla Server. Wonderful, it locks the file and my test function now works. Read the rest of this entry »

Check If File Is Available To Write/Rename/Move

Apr 14

Posted by Ricardo in ColdFusion, Java

At work we have a import procedure that reads several ZIP files uploaded to us and then imports the contents of it (XML file into the database and the picture files to their corresponding folders in our web directory).
Since that process is scheduled to run several times a day, I was having locking problems when trying to move a zip file to the work folder while it was still being uploaded through FTP by the client.
I used the approach recommended by Jeff Peters on the “Directory Watcher Dangers” on Gateways issues, by adapting his function into my import process, checking the file size in a loop (below is his watcher function): Read the rest of this entry »
