Use functions connected servlet

[ChrisChurch]

Connecting to a servlet based on JavaBridge you can do in php with Java.inc included:

$java_context()->getServlet()->doSomething($x)

where doSomething is a function like:

public String hello(String mytype, String id) {

    return "hello from MyServlet:" + mytype + id;

}

is there an equivalent in soluble-jalpha, I can see that you can get java objects etc but how to get a context or class created by me?

Can I get a class like below and execute functions in it

public class MyScheduler extends HttpServlet {

/**
 * 
 */
private static final long serialVersionUID = 1L;
Scheduler scheduler;

public void init() throws ServletException {
    // public void init(ServletConfig servletConfig) throws ServletException
    // {
    // super.init(servletConfig);
}

public String hello(String mytype, String id) {

    return "hello from MyServlet:" + mytype + id;

}

Actually I didn't port it, not understanding its purpose ;) I'll update mid-next week.

Thanks for reporting.

With the latest release 0.12.0, I've exposed the method through the DriverInterface.

Can you try this and let me know if it worked:

First update with update you composer deps to "soluble/japha": "^0.12.0" then run composer update and be sure it downloads the 0.12.0 version, then

use Soluble\Japha\Bridge\Adapter as BridgeAdapter;

$adapter = new BridgeAdapter([
                               'driver' => 'Pjb62',
                   'servlet_address' => 'xxx.yy.zz.251:8080/JavaBridge'
               ]);

$servletContext = $adapter->getDriver()->getJavaContext()->getServlet();
$servletContext->doSomething();

Thanks a lot

I have it working now:

php: $servletContext = $ba->getDriver()->getJavaContext()->getServlet(); $xx = $servletContext->hello("Test", "1"); echo $xx;

java: public class MyScheduler extends HttpServlet {

public String hello(String type, String id) {

    return "hello from MyServlet:" + type + id;

}

results in:

"hello from MyServlet:Test1"

Great, thanks

Great,

@ChrisChurch , I'm suddently regretting the name of the method $ba->getDriver()->getJavaContext()...

I would like to rename it as $ba->getDriver()->getServerContext() or $ba->getDriver()->getContext() in the next release '0.13.0'... Is it a problem for you ? and have you any preferences, for me JavaContext() is too wide, the getContext() version would be more understandable ? What do you think ?

Thanks,

Sen

With reference to the servlet spec (e.g. tomcat) a webapp is named a context, so I think the:

$ba->getDriver()->getContext() is appropriate. Not a problem for me to change it.

Thanks Chris, I've released a new version with the rename into getContext(), as it's a breaking change here's the link in the CHANGELOG

Please upgrade to 0.13.0 and thanks again.

Hi Sebastion

I have tested in working with the changed function name, but am a little surprised as I thought it would be:

$servletContext = $ba->getDriver()->getContext();

not

$servletContext = $ba->getDriver()->getContext()->getServlet();

as the servlet name is already specified in the options and context 'means' webapp., e.g:

$options = [ 'driver' => 'Pjb62', 'servlet_address' => 'xxxx-amazonaws.com:8080/Quartz/scheduler' ];

But I am still looking at how you have designed/coded it so not an authority...

Hi Chris,

Good point, but I realized the original client was returning a php.java.bridge.http.Context object, so I kept the behaviour like it was. Mostly because my java/servlet expertise is really basic ;)

I've just generated an api doc where you can have a look to the Context doc. I hope it can bring a better picture about possibilties. It's maybe contains the answer to your comment ?

In the meantime, I try to figure out what I can improve in the bridge install process. I forked the original CVS repository here on github. If you see improvements that can be done, let me know.

Thanks,

Seb
