OK - I can set the Class Path. Now - what else?

Dear all,
I read with interest the many posts in this forum debating whether to use an IDE for your Java development, or to use some other (more primitive????) means of crafting code - notepad for example. As I understand things:
If I use notepad and the command line to build, run, and compile my classes, then I will hopefully come to learn and understand how to set my class path correctly, and gain an insight into the environment in which I work - an insight moreover, that I might not happen upon if I leave an IDE to do all this for me. Ok - fine, I can use my IDE, but also do some testing on the command line to fill this gap in my knowledge.
If I use an IDE to help me build my UIs, then it is more than likely that I will progress through life without a profound knowledge or understanding of layout managers, cell renderers, event handelers etc. OK - this is fine too, and I have decided to craft my UI 'by hand' because I want a broad appreciation of Swing and anyway, after the initial pain (akin, I imagine, to child birth), it's not so bad really.
Now I feel I am cooking. I understand my environment, and the more esoteric features of Swing; I use my IDE to fashion my code - it's cool and helps me with code completion, and direct access to the API documentation as I type, and it does a whole bunch of refactoring stuff too.
I feel as if I am getting the best from both worlds now.
Would anyone argue against an approach such as this?

ChuckBing wrote:In general, a good approach. You're correct, using the IDE will make life easier.
What you have to watch out for is using it as a crutch. If it ever does something that you can't do, or don't know why it's doing "that", then you aren't learning. The next time "that" has to be done, if the IDE isn't available to do "that" for you, you're dead.
Then you'll be posting the "how do I do that outside the IDE" question here.
Make a promise to yourself: You'll learn why and what the IDE does, and read the API's - A lot!Yes, I agree Chuck. I am not comfortable with a tool doing something for me which I don't understand; which is one of the reasons I build the UIs by hand.
I also become somewhat downcast when I see people in the forums requesting code so they can simply paste it into their aplpications. Learning can be painful, but it is a necessary pre-requisiite to knowledge in my view - so copy/paste can be a most harzardous thing.
I am hoping this thread will be a small guide to new folk.
Thank you for your input,
Steve

Simple question about environment variables and setting the class path???

ok I have been trying for a few months now ontrying to set the class path..
I work with windows vista..
on the environment variables user variables,
I have the name of the variable as class
and the value as C:\Program Files\Java\jdk1.6.0_04\bin;.
where javac is...
on the system variables I have
its name as class
and the value as C:\Program Files\Java\jdk1.6.0_04\bin;.
why is this not reading javac

The PATH environment variable should have as an entry the directory containing your javac executable. The CLASSPATH should have have entries which define your library directories and entries which are your jar file libraries. In the early days, probably the only CLATHPATH entry you will need will be a '.' to indicate the current directory.
The Java tutorial covers ALL of this.

How to set the class path?-

my forlder is :C:\Documents and Settings\india
jdk is in:C:\Program Files\Java\jdk1.5.0_11\bin
can any body can help me to create a classpath for my folder?

An alternative - as stated in reply 2 in your other thread on this topic: http://forum.java.sun.com/thread.jspa?threadID=5170470 - is not to set the CLASSPATH environment variable at all. Use the -classpath switch instead.
As the documentation linked to in that reply points out: "The class search path (more commonly known by the shorter name, "class path") can be set using either the -classpath option when calling a JDK tool (the preferred method) or by setting the CLASSPATH environment variable. The -classpath option is preferred because you can set it individually for each application without affecting other applications and without other applications modifying its value."
As always, the documentation is worth reading; the available command line options worth using.

Setting the Class Path

Hi guys,
I am having problems using Textpad to run my java programs. It compiles java programs, but it doesn't allow me to run the programs. It comes up the error;
Exception in thread "main" java.lang.NoClassDefFoundError: HelloApp1
I was having the same problem when I tried to run my java programs on command prompt. To solve this I resorted to using -cp to set the classpath to the directory where my java apps were located. The path in the environment variables is pointing towards my java bin directory, so that isn't the problem. Can someone tell me how I can set my classpath permantly and where I should point the directory to, so that i can run my java progs on Textpad.
Thank You
Jaz

Can
someone tell me how I can set my classpath permantly
and where I should point the directory toYou shouldn't use the CLASSPATH environment variable to run programs. You should always use the -classpath option for javac and java--even when you don't need to specify a path. If you don't need to specify a path, then write: -classpath "". The -classpath option overrides the CLASSPATH environment variable, which is what you want. Otherwise, you will never figure out how to compile different files.
so that i
can run my java progs on Textpad.
I have a similar editor, and I was able to set it up to run simple, one file programs without package statements when I click a button. Your best bet is to find a Textpad discussion forum and ask how you can set it up to execute java programs. Or, check the help in Textpad.

How to set the default path of the tag while working with xtype "tags"

Hi,
I am working with xtype tag, where i have to select tags in the dialog box. Everything is fine, but my requirement is set the tags path.
Currently it is defaulted to /etc/tags and showing all the tags. Instead i have show only the single tag path that is required for me.
Is there any way where i can set the root path and set to my custom tag path like: /ets/tags/mycustomtags/
Thanks for the support in advance
Riyaz

Hi,
Use namespaces property to set the path. But it only works with namespaces that you directly creates under /etc/tags
so for example if you want to use or show two namesapces /ets/tags/mycustomtags & /ets/tags/mycustomtags1
then set this property as
namespaces       string[]             mycustomtags
                                                   mycustomtags1
and if you have only want to show one then
namespaces       string[]             mycustomtags
I hope it will help you.
Also refer http://dev.day.com/docs/en/cq/current/widgets-api/output/CQ.tagging.TagInputField.html
Let me know if you need more information.
THanks,
Pawan

Sun ONE Studio 4 aka Forte: How to set the output path for classes ?

Help !
Beginner's question:
Sun ONE Studio 4 aka Forte:
How to set the output path for classes ?
As default, the class files are created in the same directory as the
sources.
In opposite, both JBuilder and Together support that there is a tree
with the sources and another tree with the classes.
The first answer I got was "not possible with Forte, but just if you write your own "ANT Build script" !
a) Please point me to a ready-to-use ANT script for this purpose, if such is available
b) Is using ANT instead of the MAKE as comfortable ? Besides the separation of sourcecode and classes, I would like to keep everything else to be the same, i.e. I don�t want to edit the ANT file if I enlarge the project by directories or files.
Tia
Sincerely
Rolf

You can set S1S's options to place newly created .class files in a specific location.
Identify the compiler that is being used - Open the S1S's Tools/Options window, expand Editing and select Java Sources. Note the Default Compiler value. (If it's one if the Ant options, you use Ant to specify this option, not S1S.)
Open the S1S's Tools/Options window, expand Building/Compiler Types and select the appropriate compiler.
The Properties tab of the compiler has the property Target, which sets the filesystem where the compiler output is directed. If you choose <not set>, the .class files are written to their source directory.
When you set the Target, your change affects all classes that use this compiler.
Very few options can't be set in S1S; the challenge is finding out where they're set!

How to set the File Path to run a javascript using Plugin Code?

Hi All,
Im new to Indesign Plugin Development.Can any one help me out with my problem.
What i want to do is to run a javascript using Plugin Code.When i went through this forum i was able to find out that i should use the IscriptRunner Class to automate this.I could also figure out that the Member Function to use is "CanHandleFile" &"RunFile".
The first parameter in CanHandleFile & RunFile Member Function is to specify the path of the JavaScript File i suppose!I could also find out that IDFile has to used to set the file path Information.
But im clueless how to set the Javascript FilePath using IDFile.Can any one help me how to do this?Any Code Snippets Please?
Waiting for reply.
Thanks

Hi, Andreas Can you explain this in detail? I found it in your post before. The content of elements are returned through the Characters callback function: From ISaxContentHandler.h: /** Receives character data The parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into several chunks. But all characters in any single event must come from the same external entity so the Locator provides useful information. Note some parsers will report whitespace using the IgnorableWhitespace() method rather than this one (validating parsers must do so). @param Chars The characters from the XML document. */ virtual void Characters(const PMString& chars) = 0; What i have done is implement my own SAXContentHandlerServiceBoss, and in my file XXXSAXContentHandler.cpp, I override the fonctions StartElement, EndElement, and Characters() like below: I add the PMString xmlData to collect the file content: class XXXSAXContentHandler : public CSAXContentHandler { void XXXSAXContentHandler::Characters(const WideString& chars) { xmlData.Append(chars); } void XXXSAXContentHandler::StartElement(const WideString& uri, const WideString& localname, const WideString& qname, ISAXAttributes* attrs) { xmlData.Append("<"); xmlData.Append(localname); xmlData.Append(">"); } void XXXSAXContentHandler::EndElement(const WideString& uri, const WideString& localname, const WideString& qname) { xmlData.Append("</"); xmlData.Append(localname); xmlData.Append(">"); } } and in my program, I use the code below to call the fonction I overrided, but I dont know how I can get the String xmlData I defined in the XXXSAXContentHandler.cpp InterfacePtr<IK2ServiceRegistry> serviceRegistry(gSession, UseDefaultIID()); InterfacePtr<IK2ServiceProvider> xmlProvider(serviceRegistry->QueryServiceProviderByClassID(kXMLParserService, kXMLParserServiceBoss)); InterfacePtr<ISAXServices> saxServices(xmlProvider, UseDefaultIID()); InterfacePtr<ISAXContentHandler> saxHandler(::CreateObject2<ISAXContentHandler>(kXXXSAXContentHandlerServiceBoss)); saxHandler->Register(saxServices); bool16 parseFailed = saxServices->ParseStream(readStream, saxHandler); Can you give me any help? Thanks and regards!

Lost on the Class Path

I'm having some serious trouble with class package path issues ... ugh!
I've downloaded a fairly complex and well programmed FLA file and other source files in AS 3.0, and just started to adapt it for a custom application. When I published the FLA and packages in FLash CS3, everything worked perfectly. Then I just got Flash CS4 a few days ago, and so opened the same application in CS4, and also published it fine. Yet, once I started to make some very simple customizations, such as create a new MovieClip, and then added "linkage" to the MovieClip in the library, the trouble started. Getting the new external class to associate to the new MovieClip was not working (although it was in the same location as the other package file, with the same class package designation), so of course I went to take a look at the preferences and set the general class path. Interestingly, the class path was completely blank (I just installed CS4 that day). Yet then, why was the application still working initially with no class path set? All of your original classes were loading fine, and the application was working. So, then when I went into actually set a class path (my new class is in the same folder: .../com/parkerandkent/components/classic/photogallery ), I start getting all kinds of errors ... and now, even if I revert back to having no class path at all, the application does not work at all (when it originally did with no class path at all). Strange! I am very confused about what is going on.
There are 5 primary .as package files, all of which are linked to MovieClips in the Library:
ClassicPhotoGallery.as
Photo.as
Thumb.as
Thumbs.as
CallTag.as (the new class)
I've checked the properties linkage for each of these, and they all appear correct also.
Currently, I have all of these class paths set:
- "/Users/mac/_EXTRA/ArtMuse/GALLERY"
- " "/Users/mac/_EXTRA/ArtMuse/GALLERY/com/parkerandkent/components/classic/photogallery"
Currently, I get these these error messages, which are referring to only 3 of 5 total .as files (which are all in the same location, and all have the same class path designation - and none of these files is the new class I made, which now appears to be referenced okay).
Photo.as Line 1:
5001: The name of package 'com.parkerandkent.components.classic.photogallery' does not reflect the location of this file. Please change the package definition's name inside this file, or move the file. /Users/mac/_EXTRA/ArtMuse/GALLERY/com/parkerandkent/components/classic/photogallery/Photo .as
Thumb.as Line 1:
5001: The name of package 'com.parkerandkent.components.classic.photogallery' does not reflect the location of this file. Please change the package definition's name inside this file, or move the file. /Users/mac/_EXTRA/ArtMuse/GALLERY/com/parkerandkent/components/classic/photogallery/Thumb .as

Again, the class path package designation is the same for all 5 .as files:
package com.parkerandkent.components.classic.photogallery {
yet the application is not working, and I get only those errors posted above.
If I remove all source path designations, then I get NO error messages, and yet the application does not work (although, I swear it was working this way originally).

How to set the report path in a model plugin

I am trying to figure out how to set the report path in a process model plug-in. I can seem to figure out how to get access to it. It seems like this would be a reasonable thing to do since the plug-ins are for results processing. Does anyone know how to do this? We typically use the Sequential process model but I am trying to keep my plug-in as independent of that as possible.
Thanks.
Solved!
Go to Solution.

If I understand, you want your plug-in, when enabled, to alter the settings of any other instances of the NI report plug-in such that their reports share the same directory as your plug-in is configured to use.
If so, your plug-in can access and modify the settings of all other plug-in instances. All instances are passed to all plug-in entries point in the plugins array sub-property of the ModelConfiguration parameter. You can iterate through this array. Any element of the array with a Base.SequenceFilename equal to "NI_ReportGenerator.seq" is an instance of the NI report plug-in. Its report options are stored in the element under PluginSpecific.Options.
You can change the report options to what ever you want. Note that the ReportOptions model callback is called from the Initialize model-plugin entry point, so you might want to ensure that your changes are applied after that, so they aren't overwritten. To do that, you could make your changes in the the Initialize entry point of your plug-in, and ensure that your plugin runs last. To make it run last, you could set the FileGlobals.ModelPluginComponentDescription.Default.Base.RunOrder in your plug-in file to a value greater than 0, such as 1.0 (see TestStand Help>>Fundamentals>>Process Model Architecture>>Process Model Plug-in Architecture>>Structure of Plug-in Sequence Files>>Model Plug-in Entry Points>>Order of Entry Point Execution at Run Time).

Concatenate the field SY-SYSID, SY-UNAME and SY-DATUM for the file path

Can set the cursor in next line when user inputted one record?table control

For Dnypro Table control
I just know when data check error, we can set the cursor to the error field of current line.
Now user hope that after they inputted the data of one record, he enter the [ENTER], the cursor can be set to the next new line's first field.
I tried to use such as
[SET CURSOR FIELD 'WA_XXXX-XXXXX' LINES 5.].
But if no any error , the cursor will be automatically setted to the field which setted at Cursor position in Dnypro's attribution
Can it be realized?
Thanks.

try to use same procedure as when you program page down:
DATA: ITAB_LINES LIKE SY-TABIX,
        FIRST_LINE LIKE SY-TABIX,
        J LIKE SY-TABIX.
GET CURSOR FIELD CURSOR_FIELD.       "to see what Loop is selected
DESCRIBE TABLE IRE05 LINES ITAB_LINES.
RE05-LINES = ITAB_LINES.
    WHEN 'P+'.
FIRST_LINE = RE05-TOP_LINE + LOOPLINE_IRE05.
->      FIRST_LINE = RE05-TOP_LINE + 1.
      J = RE05-LINES - LOOPLINE_IRE05 + 1.
      IF J LE 0.
        J = 1.
      ENDIF.
      IF FIRST_LINE LE J.

Problems setting the recording path

I have recorded hundreds of songs successfully by setting the recording path to the project folders on my external hard drive. Now whenever I open a new project and go to record an audio file it ask me every time to set the recording path. I pick the location on my external, click save and then hit the record button and then the whole process starts all over.

does your drive has a Sleep mode (or something like that) preference?that's after a certain time of inactivity...goes to sleep
Might be that..

ITunes Music Folder will not play from external hardrive after setting the correct path

I've decided to try and create some more space for my music collection and decided to keep my entire iTunes library on a portable external hardrive. I researched how to do so online and was successful at first. I set the correct path from the advanced menu so that iTunes would recognize and save music to the folder on my HD. It worked fine last night, but today when I try and access it I get the, "could not be used because the original file could not be found. Would you like to locate it?" error message when I try and play a song anywhere in iTunes. I then tried to import the library from my external hardrive and then everything was duplicated. I some how reversed the duplication by using time machine and then redownloading iTunes, which is a riduculous story in itself, but thankfully, I am back at square one.
I have over 24,000 songs with a majority of them rated as well as playlists I do not want to lose. I don't understand why it will not play the songs. Can anyone help me?

If you are going to have the library on an ext HD the transfer the entire iTunes folder. This way you capture all the files - not just the music.
Launch iTunes with the 'option' key down and follow the dialog - tell iTunes to open the iTunes library file on the ext HD and things should be ok.

OK - I can set the Class Path. Now - what else?
