i want to read a pdf file and output only the text in a console. how to accomplish this? perhaps somebody can give a hint, even with pdfbox-1.1.0.jar?

There are some open source libraries available that can read .pdf files and extract the text portions from it; google is your friend here: "Java pdf read" shows the results.

i couldn't find nothing helpful with google. what i'm looking for is an example written in java.

According to PDFBox documentation (well the first page) it says it can extract text, and has a command line for that.
Since the source code is available, why not look at it for ExtractText?

How strange because when I google for "Java pdf read" and follow the second link I get this page. It has a fine manual stuffed with easy to read Java examples ...

To be fair, that's not exactly a free thing (outside of the trial).

Duh, I didn't even notice that but I'm sure there are a lot more resources available (for free) because .pdf file format is soooo common.

As I say, the Apache thing has a tool for extracting text, so I would argue it's just a case of opening up that source code and seeing what they do.

i've tried out some jars goole suggested and i could extract the text from a pdf but it looked like this

I1enti1iers 1nd Ke1word1

unusable. i was not in the mood for trying all jars google suggested. but now the AspriseJavaPDF.jar works great and the output is very proper! thank you again.


the only drawback is this:

****** There are more text found, however this evaluation version only allows you to extract max. 1000 chars per page. Simply purchase a license to remove this restriction. Asprise Java PDF Library ******

and the price of the Java PDF Reader for a single developer license is USD 998.00

hello
I recommend this lib Apache PDFBox - Apache PDFBox - Java PDF Library

PDFBox was already recommended in this thread (reply #4) so your reply is of no use and redundant; no rep points for you no matter how much you beg for it.

How strange; I don't know anything about pdf format but I thought that text was simply represented by text (sprinkled with format information). It seems that if a character isn't recognized a '1' is printed ...

1) the commons-logging-api-1.1.1.jar is in the classpath and there is a org.apache.commons.logging.LogFactory in it.
2) i don't get what the "AccessController.doPrivileged" means.

somebody can help?

The logging jar with the LogFactory class is not on the classpath.
What makes you sure that it is there?
