Translate English to some other Language in RAD or Eclipse

I have written comments in English in my Java files but now my client wants it in Spanish, So is there any tool/Plugin available in RAD or ECLIPSE IDE to convert all the comments in other language. I am using google translator to convert comments manually.

I'm not aware of any plugin like that. First, I would make sure the client really really wants this. Doing an automatic translate of highly technical text will not give a very good quality. I question if they will be usable at all, do a test translate of a couple of comments first to get approval.
If they really want something that is usable someone with language and technical skill would have to manually translate everything, which would take time/money.
But, if I had to do it, I would take the idea from this answer to automatically launch a web browser from Eclipse, and use the URL to google translate, https://translate.google.se/#en/es/${selected_text}, should work.
If the codebase is large and the comments can be easily found, such as a javadoc, I would write some script to automatically handle this. Google translate has an API you can use. See REST API doc

Every now and then a developer has to work on a code base that is in a language that is unknown to him. In this case, he would need to copy variable, class, method names to Google Translate to see what they actually mean.
The Source Code Translation in Eclipse tries to help such developers, by providing a popup with the translated words, when hovering the mouse over them. The plugin is able to handle compound words or phrases that use camelCase or underscore "_" as separation methods.
For the plugin to work, a properties file containing the word to be translated, and the translation needs to be created and added from the Preferences section of the plugin.

C++ or Java Library for automated code editing?

I am writing/planning to write a program that takes in a java file (or multiple java files), and edits and adds functions/classes/variables and then outputs a new java file (or multiple files).
Is there a C++ or Java library that
Can recognize and output names of classes/functions within a text file
Can recognize and output the names of the input arguments for said classes/functions
Can allow me to insert code at specific lines or within specific functions
Can search for a given variable name/value
Maintains original file formatting
I would prefer not having to manually code something to do the above, so any help would be appreciated.
Thank you in advance!
EDIT: I currently use Eclipse, and am unsure of how to proceed. So to further explain my question:
In eclipse, if I write a program that opens another .java file, How would I go about 'asking' eclipse to output, say, all the class names of the .java file I just opened?
Also I will explain the 'purpose' of this project to further clarify. I want to write a program that can take in any java file, and turn it into a class that can implemented remotely via RMI. To do this I will need to add an execute() function, have the file implement Task and Serializable and add a few variables, etc... Based on my knowledge, doing this in Eclipse would require manual editing of the program, but I would like to completely automate this process.
Thank you, again.

Much of what you need can be found in a modern IDE; and some very good IDEs are open source (eclipse and Intellij IDEA Community Edition for Java). You might look there to see if there are modules that suite your needs.

Looks like you are talking of a tool like eclipse. You might not be looking for a full fledged IDE, but the requirements that you have mentioned are fulfilled by any basic IDE.
If you wish to make one of your own, you can do that using eclipse rich client platform.
All that you would need from Java is the reflection API.

Analyse SWF-Files with Java

I stumbled upon the need to find out (inside Java code) which files are dynamically loaded by an SWF-file. Is there any possibility to get a list of paths of every object referenced inside?
I tried out some libraries without proper documentation and gave up. Although I ran out of Google Search Phrases... ;)
Maybe there is an external tool which can be accessed by Java via command line?
Ggreat thanks in advance

Maybe you can get to the information you need using the dump tool which is part of Apparat.
I use actionscript more than Java, so I also recommend having a look at AS3SWF which is a great library you could use to load and analyze the swf you need. Think of it as decompiling at runtime.
Either way, the SWF Format Specifications will come in handy.
I'm not sure there's something that does exactly what you want, but I imagine you could collect all the strings (DefineText tags), loop through them and run an URL RegEx against them.

I think even if you could analyze a SWF file, you can't be sure to get this information. I have Flex Project (finally a swf file) which dynamically loads some modules, but the names (URLs) of the available modules are requested from the server. So there is no chance to retrieve this information from the main swf file.

How to generate a PDF from JavaDoc (including overview and package summaries)

I have written extensive JavaDoc documentation on my application, and added lots of useful info at overview.html and package.html files (including links on the former to illustrations in doc-files/). Maven's Javadoc plugin nicely uses the standard javadoc tool to generate the classic JavaDoc frameset, but now I need to generate a PDF with the whole documentation.
AurigaDoclet generates very pretty PDFs, and I was able to make DocFlex work also. However, both ignore my overview.html and package.html files (tried both inside and outside Maven - the PDF will be a once-only thing, since I'd rather have the HTMLs on the long run).
Does anyone know how to make AurigaDoclet recoginze my non-Java files? Or, alternatively, another to generate a decent-looking PDF from either the source code or the JavaDoc-generated HTML?

Nailed it. After trying all the possible tools to generate straight from the source, I returned to HTMLDOC. It is not JavaDoc-aware, but it is so well built that a few tweaks are enough to make it generate a pretty usable PDF.
Here goes a step-by-step description of how I did it:
Download the software on the releases page;
Generate your traditional HTML docs in your preferred way (Ant, Maven, command-line javadoc - your choice);
The GUI is nice, but adding all files manually can be cumbersome, so just create a .book file with Document Type set to "Web Page", add one of the HTML files from your generated javadoc's root folder (e.g., overview-summary.html, anyone will do, it's just for reference on step 5). On the Output tab select the PDF format and set a name for it, and add other options to your heart's content (logos, colors, lots of cool stuff here). Save this project (say, myjavadocpdf.book) and close the GUI
Generate a list of all HTML files in your javadoc. I did it with Cygwin's find command (my DOS/cmd shell days are long over), but you can do anything you want, as long as you get a file list. In my case a find . | grep html$ | sort -r > files.txt did the trick;
For Windows users, dir /s/b *.html > files.txt should do the same (but keep in mind you may have to replace \s with /s if they appear like so on the next step).
Open the .book file generated on step 3 in your favorite pure text editor (as a programmer you should have strong opinions on that, so will keep my opinions to myself - NOT ;-) ) and append the list generated on step 4 to this .book file (it keeps the list of files at the end, making life really easy). Don't forget to fix the relative paths, if needed with a global search/replace (that's why you needed at least one file added on step 3 - to see which file path pattern htmldoc expects);
Now you should sort the files in a convenient order. I put my overview first, then package descriptions and each class, then the full index, and everything else at the end. Remember that any file you delete will become an external (hence broken) link, so choose wisely;
Save your .book file and re-open it on HTMLDOC. Voila: all files added and sorted. Click on generate. That's it!
You may want to fiddle with images (hint: use HTML width/height, not style/css). In the end, the resulting file is surprisingly good: nice looking and fully navigable for internal and external links. Impressive when you consider that the tool is not Java(Doc) aware at all...
EDIT: software is now free from original author; updated links, thank you #mohammed

According to the Sun JavaDoc FAQ, there's a couple of options -- mostly free, with one or two commercial offerings as well. Check it out at http://java.sun.com/j2se/javadoc/faq/index.html#print.

AurigaDoclet fails to process package.html.
For a fix see my comment at https://sourceforge.net/projects/aurigadoclet/forums/forum/339169/topic/1572199/index/page/1

If this question was bumped anyways, I can use this to link my ltxdoclet project.
This creates from the source (by being a JavaDoc plugin) documentation in LaTeX format, which you then can pass through PdfLaTeX to produce a PDF.
Optionally it also can include pretty-printed source code.

Is there a tool for non-developers (translators!) to edit resource bundles?

What we do in our company to let our software be translated by external translators is ... well .. how to put it...
cvs co someModule
ant translation.export (behind this target there is a self-made ant task, exporting all resource bundles together as one big tab-seperated text file, columns: the different languages, each row all languages for one key)
Some VB tool does something with the file (you don't wanna know)
Translators work in Excel on their column
Someone collects and merges the translations
VB tool
ant translation.import
cvs commit
...
Best case: 2 weeks between 1. and 8., development goes on...
First question: How do you handle this?
My idea was to build a tool with a web-gui that allows translators to work directly on cvs module (checkout in background and commit on "save", maybe tagging in background). We started with implementation by trainees and got something like a proof of concept. Before we go on with development I'd like to know
Second question: Do you know of a comparable tool?
and/or
Third question: Would you use such a tool?

java also provides its own resource bundle editor.

You should use gettext and Poedit. Translations are kept in separate files.

We use Sisulizer to localize our applications (.NET), for what I see in the documentacion of the application, it also supports Java, maybe this can help you.
With Sisulizer you can generate a translation project that you send to translators and when they return you it translated you can import the translation directly into the project.
