Java and html

Hi,
Does anyone know how or where I can find information on how to create a html file with the use of Java.
Thanks

Hi,
What I ment to say is: can I use
createTempFile(prefix, suffix, File directory)
to create a .html file. I suppose I can.
Thanks for the reply

Java and HTML or PHP question

I am not sure of my best course of action and would appreciate some input. My problem is this. I have written an application in java that communicates with a
micro controller and passes information back and forth.I read info from sensors and relays and make changes to them. My current GUI is set up with tables to
display this info. I am in the process of creating a graphics based interface to display the information in a web page but I am having trouble getting my
java program to update the HTML page. I have considered using java to update a database with values and then reading the database with PHP and updating the
HTML but I do not know how to get the java to run the PHP. I can use the java.awt.desktop API to display the html but I cant get it to display the .php files
due to the server issues with PHP. I am not sure what I am looking for here. Javascript? AJAX? What I want is for the user to push a button that loads a
web page and have java read that html file to determine which specific values to update, then update specific text boxes with those values from the
micro controller. I already have the communication with my current java program. I know this is all a little confusing and convoluted and I apologize for
that. I am just having a tough time formulating a plan of attack. Any ideas?
Thanks in advance,
Ray
Any ideas are welcome and greatly appreciated.

Separation of Java and HTML in servlets

I'm starting on my first Java project. It will be a basic table maintenance app using Java Servlets. My question is, what would be a good way to keep my servlet code separated from the HTML code that will be used to generate the pages I'll display to the users. Should I have separate classes that produce each type of HTML? Just looking for a place to start. Thanks.

Yes it is good idea, essential even. There are three main ways to do this.
1) Use a third party template system like TEA, FreeMarker or WebMarco.
http://freemarker.sourceforge.net/
http://opensource.go.com/Tea/index.html
http://www.webmacro.org/
2) Use the Model View Controller Pattern, the Servlet (the controller) processes the requests and dispatches it to a Jsp page (the view) containing beans that reference your data (the model). See this link ( http://java.sun.com/j2ee/blueprints/design_patterns/model_view_controller/index.html )
3) Produce your own Template system; with page loader/Parser, replacing the relevant 'custom tags' with the correct data.
My best solution depends on your circumstances,

Java and html again

i need a java code that is able to take an html file and return all the sentences which contain a word like for example finishing with *omics and then it saves the sentenses in a database

You can use a ParserCallback to get all the text in the Document.

How do I mix text and Html format in a java mail?

How do I mix text and Html format in a java mail? some part I want to keep the text format, the other part I want to use Html functions(like fond, color, etc)

You don't mix them. Pick one or the other.
However if you want to have a text version and an HTML version, so that mail readers that don't handle HTML can see regular text instead, then you could produce a "multipart/alternative" message. There's an explanation of how to do that in this article:

Differences between Java Web Start and HTML-Applets???

Hi,
I'm trying to get information about the differences between JWS-Applets and 'normal' HTML-embedded Applets.
Is it possible to develop both simultaneously in one project???
Is there a Programming-documentation that describes the differences between JWS and HTML-Applets???
Thanx!

[Java and all else] How do you document DB design?

Hello,
Although most of the technical choices are explicit in SQL (UniqueKey & ForeignKey constraints, indexes,...), the semantics of the data columns and their constraints seem better served as plain human-readable comments ("ID column: identifies the plane copy; 6 figures are enough as we don't expect to sell more than 1 million planes in a foreseeable future...").
In my current system, (EJB-based, but the DB schema is not created by the JPA-compliant ORM, but via SQL scripts), I see the following ways to write and maintain this documentation:
- SQL comments in the schema creation and patch scripts
- Javadoc comments in the Java source of the Entity classes.
- UML notes in UML diagrams(1)
- external "Architecture and design" document.
All 4 of them are used, sometimes inconsistently, for various parts of the design choices; I mean, the docs do not contradict themselves (not yet, but it's a mere question of time), but some tables are commented in SQL scripts, others are in design docs, and the details for some columns are in entity javadocs. Although each developer may find it handier to "write" the doc via his preferred medium, it becomes increasingly difficult to "maintain" theoverall documentation.
Our current situation is that most of the project team members are Java developers, so it would probably be better accepted and served if we standardized that we document DB tables and columns in Java source, but I am worried that:
- someone else pouring over our DB (ex: DBA helping us to optimize things, or other team developping a data-mining tool to leverage the historical data in DB) may not be as comfortable with Java
- this may not cover all design choices of the DB schema:
- - - - first, although that is the case currently, in the future there might not be a 100% 1-1 mapping between e.g. each entity class and a DB table. Maybe some columns will not need to be mapped anymore,...
- - - - second, I fear some DB constructs are not amenable to Java counterparts; no accurate idea there, I'm not an SQL nor JPA expert, but I presume Indexes, table partitioning, tablespaces, for example (yes, the DBMS is Oracle :o) are not taken into account in JPA mapping.
And if we document those choices at the SQL level (my preferred idea so far), this will gradually make the javadocs in the entities obsolete, or removed altogether, and that will make future maintenance of the Java source risky.
How do you document your DB design in general?
Do you have specific advices for my case?
Thanks in advance,
J.

[A DB modelling tutorial|http://www.tomjewett.com/dbdesign/dbdesign.php] (not sure whether it leverages the standard mentioned above :o)
P.S.: "Java and all else" as in, damn, I'd love to use the familiar JDC forums and people to discuss not only Java-related issues, but also [all other things that surround Java|http://forums.sun.com/thread.jspa?threadID=5422264&tstart=0] (other technologies, processes, people) and enable to make workable systems out of Java code.

Thank you again.
A couple more questions:
2. Table, and proc dictionary maintained as one or more text files. Those files and schema are all in source control.Do you mean, a proprietary text format (a la tabledesign.txt), or +.sql+ source files? Again, you seem to suggest the scehma info is present in two locations.I didn't say two locations unless you meant files. Then yes.Yes I meant two files. I trust the team to get the doc file lagging a few revisions behind the SQL file, and to correct that I would have to include one more step in the review process (e.g. "review CM actions to check that the doc file is updated consistently with the SQL source").
The tool I wrote would throw errors if the comment file didn't match the schema. And if comments were not provided. That of course doesn't stop someone from documenting a table with "a table".
You can of course keep the addtional info as special comments in the SQL, but when I did this, and even in retrospect, it seems better and perhaps easier to keep them seperate. I have done special comments in SQL before and it seems a bit of a kluge but you do have the single source. But in that case I was the only one maintaining it too.What do you mean by "special"?For code generation I have a schema file with the following (pseudo sql.)
    create mytable
       mytable_id int,
       column_foo varchar(10);
       column_fum varchar(20)
        -- Query: for_a_query (column_foo, column_fum)
    )The generator consumes the schema and generates the standard CRUD which would include a query based on the primary key.
The above comment is used to provide an additional query where the proc is named 'for_a_query' (munged with table name) and takes two parameters (column_foo, column_fum) whose type/name matches those of the table.
If we don't try to generate a browseable HTML out of the schema (although the idea is appealing, I don't have the resource to make such a tool), do you see anything kludgy in maintaining SQL comments interpersed within DDL code?
Of course that is doable.

Java and MS-Access: Login Authentication trough SQL

Hi all,
I am currently new to the world of java and would like to ask something for a school project.
We have an MS-Access database setup which we want to use as an login-database.
We can select from the tables in the database using a standard SQL query, and print out the output, but we do not know how to combine the java-string "UserID" and "Corrpass" field to compare them with the database to check if the entered login is correct.
I know this question is a little bit on the SQL side, but could you please help me? The code for printing out Usernames was founfdon the bottom of this webpage:

I'm new to java and need help please(repost)

I have an assignment involves modifying a previous assignment. the code for the previous assigment is shown below.(it was required to be done as an applet this assigment can be an application or an applet) I'm trying to modify this code to read a text file (items.txt) that looks like this:
item # description price(this line does not appear in the text file)
001 shaving cream 400.00
999 razors 30.00
I need to load the item# and price from the text file into arrays(I have no clue how to use multi-dimensional arrays in java and would prefer not to)
I need to search the arrays based on the values entered by the user (item # and quantity) calculate the total for that item then create a new text file which has each line item for that order in the form:
item# quant price per item total(price per item*quant entered)
also also I need to be able to display the four items listed above after each loop as well as all the previous item number and quantities they selected until they indicate they don't want to select anymore.
I've been working on this for days and it seems like nothing I try works. My major problems are:
1. I have no idea how to read the text file and load those 2 items into their respective arrays
2. I can't seem to create a textfile that looks like text for the output file.

First answer: You shouldn't ask multiple questions in the same thread. Ask a specific question, with an appropriate subject line (optionally, assign the number of Dukes you are willing to give for the help). When question #1 is answered and question #2 arises, it's time for a new thread (don't forget to give out Dukes before moving on).
Second answer: I think you need a Transfer Object (http://java.sun.com/blueprints/patterns/TransferObject.html). It's whole purpose is to hold/transfer instance data where it is needed. Create a class something like this:
public class ItemTO
    private String _number;
    private String _description;
    private double _price;
    public ItemTO( String number, String description, double price )
        _number = number;
        _description = description;
        _price = price
    // Getter/Setter methods go here
}then, in the code where you read in the file do something like this:
BufferedReader input = null;
try
    input = new BufferedReader( new FileReader( "c:\\a.txt" ) );
    List items = new ArrayList();
    String line;
    String itemNumber;
    String itemDescription;
    double itemPrice;
    while ( (line = input.readLine() ) != null )
     System.out.println( line );
        itemNumber = // Parse it from line
        itemDescription // Parse it from line
        itemPrice = // Parse it from line
        items.add( new ItemTO( itemNumber, itemDescription, itemPrice ) );
catch ( FileNotFoundException fnfe )
    fnfe.printStackTrace();
catch ( IOException ioe )
    ioe.printStackTrace();
finally
    try
        if ( input != null )
            input.close();
    catch ( Exception e )
        e.printStackTrace();
}As for how to parse the line of the file, I'll leave that to you for now. Are the three values delimited with any special characters?
