RE: Newbie to struts with a question on text fields
Not sure if you are using a form bean or a dynaactionform. But, specify a String type field and then validate the string and convert to numeric. Mike -Original Message- From: Nandita Rajagopalan [mailto:[EMAIL PROTECTED] Sent: Monday, December 01, 2003 1:47 PM To: [EMAIL PROTECTED] Subject: Newbie to struts with a question on text fields Hi, I have a textbox which is supposed to hold a numeric value - ie the property corresponds to a numeric datatype in the Action form. If I leave this textbox empty , I want my validate method to catch it and print an error as this field is a required field. However, when I leave this text empty, a value of 0 gets placed in the property's value . 0 is an allowed value and hence no error gets dumped. How do I get around this problem ?

RE: newbie about struts and databases
Allow me. That's a pretty involved question. The best thing you can do for yourself as a beginner is pick up a copy of Struts in Action so you can have some background on the technology and how it should work. If you are new to Java and JSP, I can recommend the WROX Press book JSP Web Development, which gives a good overview of Java, JSP, Struts, and also gives a simple example application that shows how these technologies work together. Both of these books address the subject of database access. -= J -Original Message- From: miguel angel rojas aquino [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 07, 2003 3:59 PM To: [EMAIL PROTECTED] Subject: newbie about struts and databases hi, i'm starting in Struts, and am reading the tutorials in the struts site about building applications with it, and i was thinking if there is any easy tutorial about database access using struts, so i can start more rapidly with it (and my boss doesn't get mad at me while convincing him to use struts in the new project we are starting ;) thanks in advance, and best wishes -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: newbie about struts and databases
In regards to Wendy's statement: That may be overkill for a simple app where you might put JDBC code directly in the Action class. Simple Applications Grow into Five Headed Monsters: I just wanted to agree with Wendy and encourage the use of DAO or some sort of separated database access (DAO,OJB,etc...) even in simple applications. I develop websites for small to mid-sized businesses. I made the Struts newbie mistake of placing all my logic/database access in my action classes. As my simple applications grew I began to see how much I was tying myself down by making my Actions synonymous with my logic. To make a long story short. I had a bunch of code buried in my Action classes that ultimately needed to be shared amongst several web-apps running on the same server. Early on I had seen the growing complexity of my simple applications and I began using the DAO pattern to seperate out my database access (along with implementing some other clever patterns I picked up round these newsgroups). In the end I had to take two large chunks of code out of one of my webapps so that I could share it with several other webapps. I wrote a couple of main classes that read in some configuration files to perfrom automated data retrieval with my DAO/logic classes, set up a cron job and wham-o no painful translation from Action to standalone classes just the sweet ease of a pattern gone well. In the end... try to follow the pattern even if it seems overkill... cuz it has a higher probability of pay off when your app grows a few more heads than you expected. :-D I think we all know that story.

Re: Newbie to struts
Verify that Book.java is in same directory as in BookAction.java
Otherwise u must import Book.java in ur BookAction.java
Better u put these two java's into the same package.
Hope it will work.

RE: Newbie to struts
Correct me if I'm wrong, but it seems that the compiler is not finding class
Book, which is (supposed to be) in the same default package as BookAction?
Therefore the problem has nothing to do with struts.jar.
A couple of observations...
Don't use default packages with servlets and suchlike. You get away with it
for a while but then weird things start happening - I found out the hard
way!!
Strongly recommend looking at Tomcat/ant source setup. This has the
advantage of loading your application on-the-fly without creating subdirs of
the tomcat distribution.
Are you using some sort of IDE for this (which might be screwing up the
classpath)?
Is BookActoin.java.. in your file list just a typing error, or is it really
called that? (That would do it!!)

It's a silly answer, but, have you compiled Book before BookAction?

Hi,

Correct me if I'm wrong, but it seems that the compiler is not finding
class
Book, which is (supposed to be) in the same default package as BookAction?
Therefore the problem has nothing to do with struts.jar.
A couple of observations...
Don't use default packages with servlets and suchlike. You get away with it
for a while but then weird things start happening - I found out the hard
way!!
Strongly recommend looking at Tomcat/ant source setup. This has the
advantage of loading your application on-the-fly without creating subdirs
of
the tomcat distribution.
Are you using some sort of IDE for this (which might be screwing up the
classpath)?
Is BookActoin.java.. in your file list just a typing error, or is it really
called that? (That would do it!!)

Re: newbie to struts - confirm hierachy( packages - webapps)!!
I decided to NOT use the Struts.jar, but instead use the Struts source files, and then add my own directories below the classes directory for that particular web app. That way I could tweak Struts and have a better way of replacing updates to the classes. My setup is like this: 1) Struts framework - /struts/org/apache/struts etc... with my classpath pointing to /struts 2) My framework - /vnu/com/vnu/ etc... with my classpath pointing to /vnu 3) My classes for the particular web app - WEB-INF/classes/com/mywebapp/actions WEB-INF/classes/com/mywebapp/forms WEB-INF/classes/com/mywebapp/globals WEB-INF/classes/com/mywebapp/models WEB-INF/classes/com/mywebapp/taglib with the classpath pointing to WEB-INF/classes - Original Message - From: Chuck Amadi To: Craig R.

Re: newbie to struts - confirm hierachy( packages - webapps)!!
Some people like to keep the source Java files at a separate location, and then have Ant copy them over to the classes directory, but mixing the class and java files in the same folder works too. Personally, when using a package hierarchy for my classes, I tend to just name things .\logon\Form.java But, yes you should either put your packages class files below the classes directory, or in a JAR in the lib folder. For development at least, you probably just want to put them under classes. We put these under the WEB-INF folder so that they cannot be directly accessed by a client program (e.g. Web browser), only by the application.

I was puzzled this problem for a dog's age. Thx a lot. :=) Best regards, JeanX pacificnet.com(GZ)
