JavaDoc export using own Doclet

Hi,
I'm working on a project build of several PlugIn-Projects. I want to generate a JavaDoc using my own Doclet. Within the doclet code I try to instantiate classes. When trying to instantiate these classes I always get NoClassDefFoundExceptions. These Exceptions refering to classes the "new ones" are inherited from. I put all classpath required in the "Doclet class path" field of the export wizard. Does somebody know how to fix this problem?
Thanks
H_Holli

First, there is no NoClassDefFoundException. It's either NoClassDefFoundError or ClassNotFoundException.
Second, if a NoClassDefFoundError is thrown in your custom doclet code, then the class for which the definition is not found is not in the relevant class- or doclet path.
Before trying to get your doclet to work from within an IDE, test your doclet with command line JavaDoc. If this works, you will know that you misconfigured your IDE's doclet support. If this does not work, you need to fix your doclet or your doclet configuration.
Anyways, you will have to ensure that all classes that need to be loaded by your doclet are in the doclet path. This includes all the super classes of your custom stuff, except for standard JDK and JDK tools classes. (JDK tools classes are those classes in the tools.jar which comes with the JDK. It contains the JavaDoc implementation and therefore is implictly available.)

How to count number of lines inside methods() using the Doclet API

Wrote a custom doclet using the [Doclet API|http://java.sun.com/j2se/1.3/docs/tooldocs/javadoc/doclet/index.html ] .
The purpose for the doclet is to load Java source files and create stubs (which are identical Java source files but do not contain any method implementation details).
Instead, the method implementation details need to be replaced with blank lines...
public class MyDoclet {
     private static String TAB = "\t";
     public static boolean start(RootDoc root) {
          ClassDoc[] classes = root.classes();
          // Parse through class or interface
          for (ClassDoc clazz : classes) {
               Type superClass = clazz.superclassType();
               // Print Methods
               MethodDoc[] methods = clazz.methods();
               for (MethodDoc method : methods) {
                    Parameter[] parameters = method.parameters();
                    println();
                    if (!method.isPrivate()) {
                         print(TAB + method.modifiers() + " "
                                                + method.returnType().simpleTypeName() + " " + method.name());
                         print("(");
                         for (int i=0; i < parameters.length; i++) {
                              Parameter parameter = (Parameter) parameters;
                              print(parameter.type().simpleTypeName() + " " + parameter.name());
                              if (i != parameters.length - 1) {
                                   print(", ");
                         print(")");
                         println(" {");
                         println("\n");
                         println(TAB + "}");
          return true;
As one can see, I am just creating the method and placing the opening and closing curly braces (along with a new \n line escape sequence, in between).
Am not really that familiar with the Doclet API...
Question(s):
(1) What is the best way to figure out how many lines of code are inside each method and then use a for loop to insert the exact same number of blank lines inside the methods?
(2) Is there a way to do it using the com.sun.javadoc.SourcePosition.line() method?
Would really appreciate it if someone could help me because this is an important requirement (hence the 10 Duke Stars).
Happy coding to all,
Mike

This is not possible using the Doclet API, because JavaDoc does not store any information regarding implementation detail. Although MethodDoc#position will give you the line where the method is declared, there is no way to determine where the method body starts and ends.
If you need that much information, maybe you would be better of using a tool such as Eclipse's Abstract Syntax Tree parser. AST will provide you with line numbers for each code expression, hence it is relatively easy to compute the first and last line in a method body.

Exporting using Quicktime in imovie

In iMovie, when trying to export project to make a Quicktime mov, I get an error message saying it doesn't find the imovie event. I've been storing it (and the clips) on an external drive. When I moved it to the main HD, it still can't find it. Do I need Quicktime Pro?... I'm just using the version 7 supplied with the iMac.

In iMovie, when trying to export project to make a Quicktime mov, I get an error message saying it doesn't find the imovie event. I've been storing it (and the clips) on an external drive. When I moved it to the main HD, it still can't find it.
To review the basics... iMovie '08 maintains its own resource database. This is likely needed due to the manner in which it names files during importation. While making "Finder" level changes to the name or location of you resources is immediately reflecting in the hard drive table of contents, such changes do not update iMovie's own internal database and iMovie '08 will no longer "see" them. Where the entire structure is moved manually and all data is left in tact, recovery may be as simple as just "pointing" the iMovie '08 "Event" window at the appropriate hard drive. Other changes, such as changing a filename in the folder may not so easily corrected.
Since you indicate you chose the external drive for the storage location during the import process and made no mention of your "Events" not being visible in this window, as well as, not being available for editing, I would normally assume the internal "database" is not corrupted. In addition, since you stated in your previous posting that the pre-set export option worked correctly, I would tend to suspect your problem is in the "Export Using QuickTime" module itself or in the location/disposition of your "project" resources. You could, for instance, have a bad/corrupted install of the iMovie '08 software or attempted to change something in the "Project" package itself which may be a required parameter for communication by the "Export Using QT" module. These are just initial "guesses" on my part.
Do I need Quicktime Pro?... I'm just using the version 7 supplied with the iMac.
You shouldn't. iLife '08 has its own access to the QT "structures" embedded in the Mac OS and, while nowhere as extensive as the capabilities of QT Pro, do allow for many conversion work flows. You could, for instance, open a file previously shared to the "Media Browser" or exported to your hard drive using the "Export Movie" preset option in GarageBand and see it you can convert it to another QT compression format. If you can, it would tend to support the idea that your problem is limited to the single iMovie '08 export module and not the location of your resource files.

Export using Compressor - How?

I just got DVDSP, v3, and now the "Export>Using Compressor" menu option is available. When I selected it, I couldn't figure out how to get my files to be accessible in Compressor without first doing a "QuickTime Conversion".....
So, why and/or how the purpose for "Export>Using Compressor"???
Or do I even want to do this? From what I read on the forums, it sounds like I will get the best quality final product on my pushing-the-time-limits DVD that was shot with marginally acceptable quality video (DV) by tweaking the presets in Compressor. So that sounds like I need to get uncompressed files into Compressor (....and figure out how to "tweak" it....).
If I just drop a .fcp (Final Cut Express Movie File) into DVDSP, will there be any loss of quality vs using Compressor on its own first?
Well, I guess this shows my inexperience, to be sure, and I apologize to the forum for asking "newbie" questions....
Thanks in advance for the help!
CD

There are no batch send to Compressor, but you should be able to send them one after the other and set them off in the Compressor queue.
after I start the first one the system locks me out until it is finished.
Not sure what's happening here. What versions are you using? This doesn't happen for me. I can set a number of projects one after the other to Compressor, set the process, submit it, and return to FCP to set up the next one. The Compressor queue goes through them one after the other in the order in which they're submitted.

Quality difference between exporting via Export vs. Export using Quicktime

In iMovie 08, is there a difference in quality between Exporting a movie at the largest available size via the "Export" menu item, versus using "Export using Quicktime"?
I have a very long movie of family movies (9 hours) and have been unable to do a straight export (gets to the end after 25 hours or so and gives me a non-descript "can't complete" error message), but would rather split it up into several smaller files than compromise on quality, if there is such a compromise using the Quicktime function.
If I do go the Quicktime route, what settings should I choose, or just the default. Also, Export using Quicktime option makes a .mov file. What file type does the straight "Export" function create?
thanks much!

What file type does the straight "Export" function create?
All presets are compressed as H.264/AAC content.
Also, Export using Quicktime option makes a .mov file.
The MOV file container is "generic" and may contain any form of compressed data compatible with the QT components installed on your system and which the accessing application will allow you to use. In the case of iMovie '08, proprietary and third-party components are not allowed even if installed.
If I do go the Quicktime route, what settings should I choose, or just the default.
You use the audio and video codec and settings best suited to the goals of your export. Since you have not mentioned what your are trying to do with your exported content, it is impossible to make any recommendations here.
I have a very long movie of family movies (9 hours) and have been unable to do a straight export (gets to the end after 25 hours or so and gives me a non-descript "can't complete" error message), but would rather split it up into several smaller files than compromise on quality, if there is such a compromise using the Quicktime function.
A 9 hour export at the largest (960x540) dimensions implies a 4.128 Mbps data rate which equates to a file on the order of about 16 GBs in size. As you did not mention which export/sharing option you were using or if everything was being done on a single hard drive, such an export may require a total of 48-64 GBs of available storage space for temporary, Media Browser, and target/duplicate file(s) plus free memory for rendering purposes. So one of your potential problems could be file space availability.
As a general rule, increases in the duration of your target movie may require geometric increases in either available file space or the time it takes to perform the processing. It is, therefore, usually better to "chunk" your projects (break them into smaller, more manageable segments than to process them as a single project/file) and process the segments independently. In addition most people will not watch a 9-hour movie in one sitting in any case. (I have gone as high as 5 hours but even the product of this effort amounted to less than 4 GBs of file space.)
To "chunk" an iMovie '08 project, simply duplicate your completed project as many times as needed and then divide each into manageable segments and deleting segments so as to remove the duplicated segments. I would likely consider 6 segments targeted at about 90 minutes each but division of content anywhere between 60 and 120 minutes would probably be considered "manageable" for most purposes.
In iMovie 08, is there a difference in quality between Exporting a movie at the largest available size via the "Export" menu item, versus using "Export using Quicktime"?
There should be no difference in quality if you use the same compression formats and target settings. Changing either the compression format (each of which may have its own particular characteristics) or the settings (such as the data rate which directly affects both file size and quality) will usually produce visual differences in your product.

Use own AttributeDefImpl [revisited]

So, I did what Shailesh has recommended in:
Use own AttributeDefImpl? How?
And it works quiet well. One question is left. Well, two actually.
How can I determine whether an attribute of a ViewObject is actually based on an entity's attribute?
I understand that AttributeDef.getAttributeKind() can do that. I would have guessed that ATTR_ENTITY_DERIVED is the return value to look for. The Javadocs say: "An attribute derived from an Entity Object." But a little bit down the page one can read: "These attributes are View Object attributes derived from transient Entity Object attributes."
So what's correct? Or is ATTR_PERSISTENT what I am looking for? What return value of getAttributeKind() indicates unambigously that it is an entity's attribute, transient or not?
I also thought about overriding the methods findAttributeDef(), lookupAttributeDef(), getAttributeDef() and getAttributeDefs() in ViewObject. Would it be wise (and safe) to do that? I have second thoughts about that. Right now my wrapper (which is not a subclass of AttributeDefImpl) only works on entity level.
Regards,
Sascha Herrmann

Forget both questions. I tried overriding the methods in ViewObject and it seems to work perfectly. No need to determine whether the attribute definitions are entity or VO definitions.
So .... BC4J is extensible there.
Anyway thanks for your assistance.

Schema Export using DBMS_DATAPUMP is extremely slow

Hi,
I created a procedure that duplicates a schema within a given database by first exporting the schema to a dump file using DBMS_DATAPUMP and then imports the same file (can't use network link because it fails most of the time).
My problem is that a regular schema datapump export takes about 1.5 minutes whereas the export using dbms_datapump takes about 10 times longer - something in the range of 14 minutes.
here is the code of the procedure that duplicates the schema:
CREATE OR REPLACE PROCEDURE MOR_DBA.copy_schema3 (

IMovies - Export Using Quicktime - can't find the finished file - help please!

Please help. I exported several imovies projects to a designated file on my mac, using Share - Export using Quicktime and then I uploaded them to Youtube.
I did this successfully several times, now when I export a project, it takes about 45 minutes to export it, then I can't find them anymore.
I have read several threads, which suggest looking in the iMovie projects folder and locate your project Right-click to get to "show package contents" and they are not there.
It looks as if it goes through successfully, no errors but this is so annoying as I am wasting hours sharing and then can't find it. Please help anyone.
Thanks

Hi Gee
I originally spent about 10 hours uploading 3 clips directly from imovies to Youtube to a private channel and they couldn't find any signs of my 3 uploads. So I read threads that said export to Quicktime from imovies and then load them to Youtube that way. I did that for 3 short, 10 minute videos and it worked fine. It changed the thread to .mov and it worked.
Then perhaps I changed something (not sure what) but now when I use Export to Quicktime, it spends 1 hour or so doing the motions and completes but when I go to the allocated folder to retrieve it. It can't be found. I read threads and this seems to be a regular occurrence but I haven't read any replies that has solved this issue.
Hope that's clearer.

Can I export using a single dump directory to multiple locations in oracle

I'm trying to do a full database export using expdp utility in oracle 10g. I have a single dump directory that is mapped to a particular file location say /export/dump. I don't want the entire dump file to be stored in the above path. Instead I want the dump to be distributed among multiple files. I know that this can be done using FILESIZE parameter which will distribute the contents to multiple files according to the size we have specified.
My problems comes here, I want to export my data to multiple locations, the path is different than what I mentioned above, say /first/dump. Now my question is should I create multiple dump directories for each location before exporting or can I omit directory attribute in expdp and specify the complete path in the FILE parameter itself.

No. EXPDP needs the server component LOGICAL DIRECTORY. If you don't specify the directory, it will go to the default EXPDP path which will be mostly /rdbms/log. It's defined by the parameters DATA_PUMP_DIR.
You will have to specify directory attribute if you want to point your dumpfile to go to any specific location and you cannot give the directory path in the file name in EXPDP (unlike conventional exp)

Failed to export using the options you specified. Please check your options

Hi..
i was using crystal report10.5 with visual studio 2008(c#)..
now im migrated to visual studio 2010....and i have installed these setups http://www.sdn.sap.com/irj/boc/crystalreports and http://www.sdn.sap.com/irj/sdn/crystalreports-dotnet ...
when i open my project it will ask to convert crystal reports and i have converted ...reports are working fine but in tool bar if i click and select a pdf format to export it will display a error message Failed to export using the options you specified. Please check your options and try again. and if i click on print button it is not working(i have set printmode=pdf)...when i was working on vs2008 both were working fine but in vs2010 it is not working..

Hello,
What type of app you are using? A win app will not have this option. Also what FW are you using? Have you made changes to the viewer(after migrating) and ensure that you are using the 13.0.2000.0?
Take a look at [this|Export and print problem; thread, also.
Thanks.

Exporting Using Expert Settings Problem

When I try exporting using expert settings, which is pretty much necessary, any video that I export, in just about any format, but usually .mov or .mp4 looks very strange. Any moving objects appear to be broken up by horizontal lines. I do not know much about these sorts of issues, but I'm guessing it's a problem with the frame rate. I've tried just about every frame rate and nothing seems to work. Thanks for your help!
P.S. Same thing happens when exporting from iMovie!

It means the timeline settings. If your project is DV, then it will export a DV quality file. If your settings are Offline RT, it will export an offline RT formatted Quicktime...if they are 8-bit uncompressed, an 8-bit uncompressed QT...etc. And the same frame rate as well, 23.98, 29.97 and so on.
It basically means that no further compression is occurring.

Exporting using QuickTime informations

I've a camcorder by Sony, HDR-CX305. It makes AVCHD files at 24Mbps data-rate.
I have not problem to import and work with them but, for watching my movies on PS3, I use to export in MP4 with codec H.264.
I don't know what number I have to use for best result. I've tried with 24000 kbps data-rate and it seems be good but I like to know from who has more experience with H.264 codec.
If any person has best method to export on PS3 please, let me know it.
Thank you.

Try this.
Export using QuickTime.
Compression type mpeg4.
Video options h.264, 1920x1080, data rate 16000 Kbps.
For keyframes choose automatic or 24.
You can adjust data rate up or down if you like.

FCP Export Using... vs. stand-alone Compressor

Hi
I have a 90 minute HD sequence in FCS2, which I'm now building test DVDs from. Not having used Compressor, I'm wondering which of the following workflows people recommend:
- In Final Cut, Export Using Compressor, set up preset, and submit; or
- In Final Cut, Export Quicktime, then in Compressor, import .mov and process
In theory, are they doing the same thing? The "Using Compressor" export brings up a "Compressor Processing" window with frame numbers ascending pretty slowly, the progress bar is just a big barber-shop pole (it doesn't fill left to right), and there's no "expected finish time", so I don't know if it's really saving me any time. At least the Quicktime export gave me a nice progress bar and only took an hour or so.
MacPro 2x2.66GHz, 4GB RAM, by the way.
Sequence is ProRes HD (High) 1920 x 1080i.
Any points of view welcome ... thanks!

Silal is correct - Export Using Compressor, especially with unrendered timelines, produces the best quality that Compressor has to offer when going .m2v because it forces Compressor to render directly into the MPEG-2 stream. Of course, this usually takes 3-5x as long as an encode of a reference movie.
Before we had Color, many of us did color correction in FCP and that's really when it helped to use this process (export using Compressor, unrendered). Now that we have Color (and Color renders footage for us), this workflow is less appealing.
Since you've got a Mac Pro, when exporting directly to Compressor, you can't use virtual clustering, so not only are you using a slower process, but you can't even make use of all your processors.
In your case, since you're working in 1080 ProRes422 HQ, export a reference movie, crank up Frame Controls' Resize to Better, and make use of virtual clustering.
