Ciao,

I want add a new tab in the patient dashboard (over Overview, Regiments, Encounters, Demographics, Graphs).
How can I do?

Best Regards and thank in advance,

This is done with an extension point in a module.

You can see an example in the formentry module:
Define the extension class and which point its extending:
http://dev.openmrs.org/browser/openmrs- ... ig.xml#L39
and define the java that does the work on the extension point:
http://dev.openmrs.org/browser/openmrs- ... abExt.java

Ciao,

In the first place thanks for reply.
I have installed successfully the OpenMRS for developer, I have read the "Module" article and now I'm reading the "Creating Your First OpenMRS Module" article.
I have check-out the basic module and edit it a little bit (name, author, etc.) but when I execute ant build command the DOS-Shell gimme an error:

Code: Select all: BUILD FAILED Target "build" does not exist in the project "BasicModule".

Also ant compile and ant dist gimme the same error

What can I do?

Best Regards and thanks in advance
Matteo

NOT ant build but ant package-module (or ant -buildfile build.xml)
However the ant version of Eclipse 3.3.0 is not working with OpenMRS modules, gimme the following error

Code: Select all: error starting modern compiler

I must use my shell version.
I will try Eclipse 3.3.2

Ant building should work within eclipse...so you must have some settings that are effecting it. Look in your eclipse preferences for the compiler settings. Try setting it to java 1.5 instead of 1.6.

I have deployed the basicModule and customized it exampleModule.
I have add the follow code in Referenced Libreries --> metadata --> config.xml

Code: Select all: <extension> <point>org.openmrs.patientDashboardTab</point> <class>@MODULE_PACKAGE@.extension.html.ExamplePatientDashboardTab</class> </extension>

I have add the follow code in src --> org.openmrs.module.examplemodule.exention.html --> ExamplePatientDashboardTab.java

Code: Select all: package org.openmrs.module.examplemodule.extension.html; import org.openmrs.module.Extension; import org.openmrs.module.web.extension.PatientDashboardTabExt; public class ExamplePatientDashboardTab extends PatientDashboardTabExt { public Extension.MEDIA_TYPE getMediaType() { return Extension.MEDIA_TYPE.html; } @Override public String getPortletUrl() { return "patientExample"; } @Override public String getRequiredPrivilege() { return "Patient Dashboard - View Example Section"; } @Override public String getTabId() { return "PatientExample"; } @Override public String getTabName() { return "Example"; } }

Now I see the tab "Example" in the patientDashboad

For see a simple page with a javascript, for example

Code: Select all: <html> <body> <script language=javascript> //says the language is javascript document.write("Hello World!"); //prints Hello World! //stop JavaScript Code </script> </body> </html>

How can I do? I suppose that I must edit the file web --> module --> portlet --> PatientExample.jsp but I don't understand :cry:

Someone can help me, please.
Thanks in advance,
Matteo

Close. You said to use the portlet named "patientExample".

public String getPortletUrl() {
return "patientExample";
}

This corresponds to a patientExample.jsp portlet in that web/module/portlet folder -- case is important.

Using the formentry module as an example again:
The extension code:
http://dev.openmrs.org/browser/openmrs- ... abExt.java
The portlet:
http://dev.openmrs.org/browser/openmrs- ... tForms.jsp

Thanks for reply
It's mandatory use a portlet? I want only a simple html web page like this:

Code: Select all: <html> <body> <script language=javascript> //says the language is javascript document.write("Hello World!"); //prints Hello World! //stop JavaScript Code </script> </body> </html>

by **ben** on Nov Wed 28, 2007 9:54 am

Yes, you must use portlet. However, in the openmrs world a portlet is just an snippet of html code that is included on some page. You can create the patientExample.jsp page with exactly that text to get the effect you want.

For verification, you can see how the extension point is used via the code on the patientDashboard.jsp page:
http://dev.openmrs.org/browser/openmrs/ ... m.jsp#L147

Work...cool! :mrgreen:

Now there's a problem :cry:

I want insert into patientExample.jsp a simple applet.
I create a .class from this java file

Code: Select all: import java.applet.Applet; import java.awt.Graphics; public class HelloWorld extends Applet { public void paint(Graphics g) { g.drawString("Hello world!", 50, 25); } }

and insert the applet into patientExample.jsp in this way

Code: Select all: [...] <jsp:plugin type="applet" codebase="." code="HelloWorld.class"> </jsp:plugin> [...]

The file class is in the same directory of patientExample.jsp
So:

Code: Select all: web |_module |_portlets |_HelloWorld.class |_patientExample.jsp

But the applet don't work. I think that the problem is that the browser don't see this folder, I suppose that I must copy the HelloWorld.class file in another folder....where?
I thinks that insert an applet is more important cause the Web is full of interesting applet

Thanks in advance and sorry for disturb,
Matteo

Hmm, unfortunately I don't have any experience with applets. Do you need to reference the full path to the .class file? If you put it in the portlets folder, you could see it via /openmrs/module/yourmoduleid/portlets/helloWorld.class

OR, if the .class file just needs to be in the classpath, you can drop that .class file into the "lib" folder in your module. It will then be copied over during module load in openmrs.

OR, you might need to just drop the .class file into the jar file. Do you have the java file for it? What is the package of the .class file?
