Thanks for the reply.
No I did not move it to the first in the list but doubt that would make a difference.
And yes I have tried to rename it to something else and still broke. The name in the source is actually something else, I posted as "db3" for the purpose of asking the question. The real source name is "abdominaltrauma" and it is hard to imagine it is reserved anywhere.

Thanks you for looking at the problem.

You could also look for some code online to intercept the system output and save it to someplace. But it's kind of shaky if you had only webapps directory to put the file. You probably don't want to reside it right under webapps. And if you put it under your application's, say log or tmp directory, you may have problem to re-deploy your application -- I had done that before. I was not able to un-deploy the application successfully because the log file was open.

Good luck.

Hi ranchers, I have this problme that I could no figure out. Any help is appreciated. Following are part of the context.xml file for my application, which needs to make connections to any of them depending on user's selection.
<Resource name="jdbc/db1" auth="Container" type="javax.sql.DataSource" username="username" password="password" driverClassName="net.sourceforge.jtds.jdbc.Driver" factory="org.apache.commons.dbcp.BasicDataSourceFactory" url="jdbc:jtds:sqlserver://serverIPAddress/db1" maxActive="200" maxIdle="2" maxWait="200"></Resource> <Resource name="jdbc/db2" auth="Container" type="javax.sql.DataSource" username="username" password="password" driverClassName="net.sourceforge.jtds.jdbc.Driver" factory="org.apache.commons.dbcp.BasicDataSourceFactory" url="jdbc:jtds:sqlserver://serverIPAddress/db2" maxActive="200" maxIdle="2" maxWait="200"></Resource> Resource name="jdbc/db3" auth="Container" type="javax.sql.DataSource" username="username" password="password" driverClassName="net.sourceforge.jtds.jdbc.Driver" factory="org.apache.commons.dbcp.BasicDataSourceFactory" url="jdbc:jtds:sqlserver://serverIPAddress/db3" maxActive="200" maxIdle="2" maxWait="200"></Resource> <Resource name="jdbc/db4" auth="Container" type="javax.sql.DataSource" username="username" password="password" driverClassName="net.sourceforge.jtds.jdbc.Driver" factory="org.apache.commons.dbcp.BasicDataSourceFactory" url="jdbc:jtds:sqlserver://serverIPAddress/db4" maxActive="200" maxIdle="2" maxWait="200"></Resource>
The problme is, the application can obtain connections to db1, db2, db4 but never db3. The error message was "Name db3 is not bound in this Context".
The way the application obtains connection is:
InitialContext initCtx = new InitialContext(); Context envCtx = (Context) initCtx.lookup("java:comp/env"); DataSource ds = (DataSource) envCtx.lookup("jdbc/" + dbName); return ds.getConnection();
(dbName is either db1,db2,db3 or db4 and lowercased before being looked up)

And all the four databases are hosted by the same sql server. I checked there wasn't a typo or anything.

Thanks in adavance for your help.

Hello,

we have set up an env where IIS forwards jsp/servlet to tomcat using Jarkata/ISAPI. Everything works fine until receltly new situation arise and we are kind of stuck.

First, say the IIS server IP is 1.2.3.4, and one tomcat instance is installed their too. Virtual host myHost.org is pointing to the ip and using IIS/Jarkata to serve servlets from application "CatMouse" in tomcat. Now we have a new application "HiddenCatMouse" deployed under the same tomcat. Another virtual host (with https) mySecureHost.org is pointing to the same IP. Our concerns then becomes, how do we do to prevent users from accessing the secured "CatMouse" from un-secured channel? I mean, supposedly user is able to do this "http://myHost.org/CatMouse/catchMouse.do". Now that I have the "hiddenCatMouse" run by the same tomcat, what do I do to prevent user from typing in "http://myHost.org/hiddenCatMouse/catchMouse.do", where "hiddenCatMouse/catchMouse.do" would be available only from "https://mySecureHost.org/hiddenCatMouse/catchMouse.do".?


I hope I have made it clear and I apprciate any comments in advance.

Thanks,

Ben

1. extend JOptionPane
public class MyOptionPane extends JOptionPane { public MyOptionPane(){ new JDialog().setModal(true); } }

2. have the component, say comp that contains the tabbed pane implements "ChangeListener"

3. in your "public void stateChanged(ChangeEvent e) "
method, instead of JOptionPane.showMessageDialog(this,"show me before going to the selected tab");
use MyOptionPane.showMessageDialog(this,"show me before going to the selected tab");

Gook luck.

Check out SwingWT(Swing and awt). It has something similar to it.

How about "JFileChooser"?

Good luck.

in the ranch SCJD/SCJP forum there are lots of good talks about it -- since you passed SCJP, you may find it is very helpful whether you are going to take SCJD or not regarding MVC.

Good luck.

You must have had
south.add(northButton, BorderLayout.NORTH); south.add(souththButton, BorderLayout.SOUTH); south.add(westButton, BorderLayout.WEST); south.add(eastButton, BorderLayout.EAST);
Instead
JPanel southCenter = new JPanel(new BorderLayout()); southCenter.add(northButton, BorderLayout.NORTH); southCenter.add(souththButton, BorderLayout.SOUTH); southCenter.add(westButton, BorderLayout.WEST); southCenter.add(eastButton, BorderLayout.EAST); south.add(southCenter, BorderLayout.CENTER); south.add(new JTextField(), BorderLayout.SOUTH);
HTH.

Yes, other than set the cell editor to be a combo box, you need to set the cell renderer (view -- when/where users can see).
Here is a custom one that you can set for the "time period" column:
class MyTableCellRenderer extends JComboBox implements TableCellRenderer { public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { //do a little bit cheating to set the value addItem(value); setSelectedItem(value); return this; } }
then
timeperiodColumn.setCellRenderer(new MyTableCellRenderer());

Good luck.

ps. To be just on the safe side, to prevent MyTableCellRenderer (now a JComboBox) to get too many items added, do "removeAllItems()" before "addItem(value)".
If the our renderer was a Label, text field, there is no such worry.

If you google "Java print", you got some very usefull hints/helps.

Good luck.

How did you get passed with these two identical constructors?
public RadioAddDialog(JDialog parent){ super(parent, ""); initDialog(); } public RadioAddDialog(JDialog parent){ super(parent, ""); ini_bgroup.add(ini_yes); ini_bgroup.add(ini_no); pane1.setLayout(new FlowLayout()); pane1.add(ini_yes); pane1.add(ini_no); initDialog(); }
You probably had it compiled ok before and edited the class again. The two same constructors will fail the compiler. Remove the one that does not have the Radio Buttons added to pane1 and try again.

I worked on a project for Uni. of Chicago a while ago only not to finish it before moving to Utah. I am able to find a reference here from IBM. Hope it helps.

Good luck.

There are lots of examples if you google "FileChooser".
Here is one of them.

Good luck.

Why do you have jButtonMoreDataActionPerformed method while actionPerformed is already there for you?
Nothing wrong with having it though but did you have someway to invoke this
jButtonMoreDataActionPerformed method when the button gets clicked?
