Good point, I am actually! I'll try Firefox and see what I get. Thanks Bear.

Hi Chandra,

I tried adding <%@ page isErrorPage="true" %> to my error page, but it still isn't working. Is there anything else I'm missing beside this code and what I've already placed in my DD?

Hi Manoj,

I noticed you posted the exact same message Please Help Me in this forum earlier and you were told to look else where for assistance. I don't think starting a new thread with a different name will help much.

If you're looking for help on how to solve your questions, as opposed to just straight answers, I think you would find better reception. Try the beginner/intermediate Java forums, they may be better suited.

Hi,

I wasn't sure which forum this was best suited for, so my apologies if this is the wrong place. I'm trying to catch HTTP Error Responses like 404, 500, etc using the error-page element in my deployment descriptor.

For example I have this in my web.xml file:
<error-page> <error-code>404</error-code> <location>/error.jsp</location> </error-page> <error-page> <error-code>500</error-code> <location>/error.jsp</location> </error-page>

When I enter in a url like http://localhost:8080/myapp/nonsense, where nonsense doesn't exist, I get my browser's or container's response depending on the error code instead the error.jsp page I've prepared.

How can I properly catch these?

Check your for loop. Trace through each loop, paying careful attention to the value of your i variable as you go along, and take a look at your loop condition as well. You'll see why it only prints once when you enter 3.

I'm certain there is a more elegant solution, but I would just test the incoming paramater to see if it's null or not.

if (request.getParameter("my_parameter") != null)
{
//do something
}
else
{
//do something else
}

I agree with Bear, if you want to backup your database, then Servlets and JSP is a poor choice. You'll have to create something in DOS since you're using Windows to run a MySQL dump on the interval you want.

a process should trigger automatically from the server and take all the backups daily or whatever.

Are you referring to backups of your database? Please clarify.

Hi Steve,

Regarding my first post, I assumed you were displaying "remote data" that was retrieved from a database which would typically be generated by submitting an SQL statement to it.

So I was proposing you make a query that will include the user's parameters.
ex.
"Select * from Some_table" would be your first query, possibly.

"Select * from Some_table Where Some_table.some_attribute = " + attribute would be something your second query could be like.


Are you in fact using a database, and servlets? Or if not, how is this original page being created?

Hi Steve,

Yes you can do this. You'll have to make a form, containing that input box you mentioned, and have it post to a servlet. This servlet can take those parameters and refine the displayed information by submitting a query simliar to what was used to generate the page in the first place, but this time including the submitted parameters in the WHERE claus.

After retrieving the results, attach them to the request object and forward back to the JSP page and display the updated information.

Hi Satou,

You're right, it was referring to another WriteUpBean.class file I had in another webapp!

Thank you so much for you help!
Jenn

Hi Satou,

I thought about what you said and deleted my WriteUpBean.class file. I then recompiled it and tried to then compile my WriteUpModel but I still get the same error.

I've even renamed the method in my WriteUpBean to something completely different, like getJenn() but it just brings the same error with the getJenn() method unresolved.

I'm at a complete loss here. Any ideas?

Hi,

I have the following class acting as a simple bean to store the details of written articles as shown below.

package acs.beans; public class WriteUpBean { private int ID; private String title; private String content; private String updated; private String author; public void setID(int ID) { this.ID = ID; } public void setTitle(String title) { this.title = title; } public void setContent(String content) { this.content = content; } public void setUpdated(String updated) { this.updated = updated; } public void setAuthor(String author) { this.author = author; } public int getID() { return this.ID; } public String getTitle() { return this.title; } public String getContent() { return this.content; } public String getUpdated() { return this.updated; } public String getAuthor() { return this.author; } }

I have a model that uses this bean as follows:

package acs.models; import java.sql.*; import java.util.*; import acs.beans.*; public class WriteUpModel { public ArrayList getAllWriteUps(Connection connection) throws SQLException { Statement statement = connection.createStatement(); String query = "SELECT * FROM WriteUps ORDER BY WriteUps.title"; ResultSet resultSet = statement.executeQuery(query); ArrayList writeups = new ArrayList(); while(resultSet.next()) { WriteUpBean writeup = new WriteUpBean(); writeup.setID(resultSet.getInt("ID")); writeup.setTitle(resultSet.getString("title")); writeup.setContent(resultSet.getString("content")); writeup.setUpdated(resultSet.getString("updated")); writeup.setAuthor(resultSet.getString("author")); writeups.add(writeup); } return writeups; } }

My problem is that I cannot compile this model, I get the following error:
C:\Tomcat\webapps\acs_admin\WEB-INF\classes\acs\models\WriteUpModel.java:23: cannot resolve symbol symbol : method setUpdated (java.lang.String) location: class acs.beans.WriteUpBean writeup.setUpdated(resultSet.getString("updated"));

I don't know what is wrong with the setUpdated method. The other methods work, so I can only think that setUpdated is a reserved method name and cannot be used?

Any help with this would be greatly appreciated!

Hi Ben,

I need to make a HTTP posts from one application to another, whereas the two applications are both maintained in the same container.

I'll take a look at the libraries to see if I can figure it out!

Thanks,
Jenn

Why not just add some administrator components to the application?

I had done that originally, but these two sites are being used to replace an old static website and the network administrator insists they be separated so he can apply SSL to the administrative end. He demanded complete separation of the two sites, so my hands are tied in this case.

Any suggestions?
