Problems with images from shared resources in PDF output [message #517776]

Like most of the folks here, I'm pretty new to BIRT but have been playing with if for the past few weeks.

I've managed to make awesome reports so easily and in a blink of an eye.

I'm using BIRT 2.5.1 and my problems is that reports that I try to generate in PDF format seem to have problems to output the images (Haven't tried charts yet...)

Every time I try to output a PDF report featuring a JPG image, instead of it there's a text saying "Current report item is not supported in this report format." If I use an embedded image the resulting report is normal, but I need the images to be from a shared resource.

This is the configuration of my PDFRenderOption (By the way, I'm using a Servlet whose only purpose is to print the report. It is to be deployed to a Weblogin 9.2 Server. Everything works awesome but the images):

...

design = birtReportEngine.openReportDesign( sc.getResource("/Reports/"+reportName+".rptdesign").toString().substring(6) );
//create task to run and render report
IRunAndRenderTask task = birtReportEngine.createRunAndRenderTask( design );		
task.getAppContext().put("BIRT_VIEWER_HTTPSERVLET_REQUEST", req);

PDFRenderOption options = new PDFRenderOption();
options.setOutputFormat(HTMLRenderOption.OUTPUT_FORMAT_PDF);
resp.setHeader(	"Content-Disposition", "inline; filename=\""+reportName+".pdf\"" );			
options.setOutputStream(resp.getOutputStream());

options.setImageHandler(new HTMLServerImageHandler());

task.setRenderOption(options);

//run report
task.run();
task.close();
...

Everything, Images, Report designs is in the WebContent Folder. Images are in WebContent/Images and report designs are in WebContent/Reports.

Hope anyone helps me out with this.

Can you try an embedded image?
Also comment out the image handler line and try that.

Hi Jason,

Thanks for your fast reply.

In fact at first I didn't have any image handler. I added that one (and the one for file based images) but none helped...

I wouldn't mind using embedded images but the fact is that I use plenty and that makes my WAR very expensive in size since I already use most of the images in JSP and I'd love to reuse to make it as practical as possible.

Anything I can do about that? I'm open to any suggestions.

Thanks!

I just wanted you to test it to see if the image is coming in.
Your code should be working. Can you post one of your report designs?
I am interested on how you included the image (URL, Expression, etc);

Hey Jason.

Sorry for my late reply.

Here is the report design. It is extremely simple. It just has a table and didn't even finish it since I had the problem with the images.

As you can see, all I have is an embedded image in a cell and an image from a shared resource, in this case, from the WebContent/Images folder.

Only the embedded image is displayed. I use the BIRT report design view from Eclipse. I'm using Galileo 3.5.1 and Birt 2.5.1

Here is the code:

You'll notice a data source and data set that I really don't use for the time beign but I added the because I was in need of a dynamic image. I stripped everything out to see if there was any problem elsewhere but as you can see, this is just a dead plain simple report that can't show a shared resource image.

Hope that helps. If you need any other piece of core or the rest of the project just let me know.

Re: Problems with images from shared resources in PDF output [message #518313 is a reply to message #518294]

The issue is that the uri is not complete. Try to enter something like
the following expression:

fp = reportContext.getHttpServletRequest().getRequestURL();
lt = fp.lastIndexOf("/");
fp.substring( 0, lt) + "/WebContent/Images/logoBMX.jpg";

Another option is to use an image from the resource folder ( you can set
in preferences) put your image in that directory in the designer, and
include it in your report. When you deploy to the WebViewer you can set
the resource folder in the web.xml(relative or full path). If you are
using the report engine api you can set the resource folder using:

config.setResourcePath("C:\\myresources");

Jason,

I'm sorry, I know this may sound stupid but this code:

Jason Weathersby wrote on Wed, 03 March 2010 12:43

Try to enter something like
the following expression:

fp = reportContext.getHttpServletRequest().getRequestURL();
lt = fp.lastIndexOf("/");
fp.substring( 0, lt) + "/WebContent/Images/logoBMX.jpg";

It is a javascript, right? Where should I put it? I know this is basic knowledge but I'm still having my way around this powerful suite.

Also for the other tip about:

config.setResourcePath("C:\\myresources");

Since it is a Webapp, is it alright if I use something like:

config.setResourcePath( servletcontext.getResource("WebContent/"+"Images") );

Thanks for your time and advices. Will try both.

There is a fx button for the expression of the URI for the image. Just
put it in the expression. And yes it is JavaScript.

your resource path setting should work.

I wasn't successful either while trying to find the object type of "config" to try the approach in Report API:

config.setResourcePath( servletcontext.getResource("WebContent/"+"Images") );

What kind of object is "config"?

Thanks

config is the instance of the EngineConfig class.
Can you add a data item to the top of the report with the expression:
fp = reportContext.getHttpServletRequest().getRequestURL();
lt = fp.lastIndexOf("/");
fp.substring( 0, lt) + "/WebContent/Images/logoBMX.jpg";

See if this matches the location of the image. Do the same thing for
reportContext.getHttpServletRequest().getSession().getServle tContext().getRealPath('/webcontent/images');

and finally a third data element with //I i do not believe this method
will work because it returns a jndi location I believe
reportContext.getHttpServletRequest().getSession().getServle tContext().getResource('/webcontent');

Also try and change:
servletcontext.getResource("WebContent/"+"Images") );

to

servletcontext.getRealPath("WebContext/" +"Images"));

I did not think about this when I first replied, but if you are writing
your own servlet you need to add the request object to the app context
so the script engine can get access to the request.
To do this when you create a new task to run the report add:

task.getAppContext().put(EngineConstants.APPCONTEXT_BIRT_VIE WER_HTTPSERVET_REQUEST,
req );

EngineConstants is in this package:
org.eclipse.birt.report.engine.api

BTW the above expressions will be null in the designer, you need to
deploy the report to test it.

Hey Jason, you are really being very helpful, I'm learning tons just from this problem.

Look, here are the outputs of the data items:

DataItem 1:

Data (id = 63) seems to output:

http://127.0.0.1:55360/viewer/WebContent/Images/logoBMX.jpg

Data (id = 63) definition:

        <data id="63">

                    <expression name="expression" type="javascript">fp = reportContext.getHttpServletRequest().getRequestURL();
lt = fp.lastIndexOf("/");
fp.substring( 0, lt) + "/WebContent/Images/logoBMX.jpg";</expression>
                    <property name="dataType">string</property>

Funny thing is that I don't have a viewer directory like the path Data Item 1 outputs...

I couldn't deploy the EAR to my Weblogic due to "org.eclipse.core.runtime.CoreException: Extended Operation failure: org.eclipse.jst.j2ee.internal.archive.operations.EARComponen tExportOperation " but the preview threw those.

Does any of this ring a bell?

Ok Jason...

I know giving support for tons of people with problems with BIRT is way too much for someone to handle on a regular basis and I feel so bad troubling you with problems that may be lack of knowledge...

The fact is I used another approach. Since embedded images display fine, I tried making a library with the images embedded in it so I can import them in my reports and if I need to change an image I just have to edit one single library but the fact is that now the report is blank because I think birt can't find the library...

This is the path in my report:

        <structure>
            <property name="fileName">WebContent/Reports/bnmxLib.rptlibrary</property>
            <property name="namespace">bnmxLib</property>
        </structure>

As you can see, my original problem might be related since birt while constructing the PDF might have problems with relative paths.

I tried editing the resources path in config without any luck.

Any ideas on this? Might this be a bug?

Dan

Dan,

Can you try to put the library in the same directory as the report and
change the xml snippet in the report to just bnmxlLib.rptlibary?

You should be able to set the resource folder and put them there as well.

In the previous test did this:
Data (id = 64): + A BIRT exception occurred: Error evaluating Javascript
expression. Script engine error: TypeError: Cannot call method
"lastIndexOf" of null (#1)
Script source: , line: 0, text:
fp =
reportContext.getHttpServletRequest().getSession().getServle tContext().getRealPath('/WebContent/images');
lt = fp.lastIndexOf("/");
fp.substring( 0, lt) + "/WebContent/Images/logoBMX.jpg";. See next
exception for more information.
Error evaluating Javascript expression. Script engine error: TypeError:
Cannot call method "lastIndexOf" of null (#1)
Script source: , line: 0, text:
fp =

lt = fp.lastIndexOf("/");

Happen when you deployed to your app server?

I wonder if WL denies getRealPath()

this output

http://127.0.0.1:55360/viewer/WebContent/Images/logoBMX.jpg

Looks like you ran it in the designer (or the preview with webviewer).

Hi Jason

You should be able to set the resource folder and put them there as well.

Now when deployed I can see the embedded image in the library inserted in my report.

Quote:

Yes it did.

Quote:

It does. Only when deployed. When in workspace works just like Tomcat. That's why I use getResource and force the url to string...

I upgraded to BIRT 2.5.2 and the results are the same but now the message that appears where the "shared image" should, reads "The resource of this report item is not reachable." and the log shows:

Mar 4, 2010 2:13:09 PM org.eclipse.birt.report.engine.emitter.EmitterUtil getImage
SEVERE: null

As you pointed out the resources can't be found and I'm getting a lot of trouble trying to make them available.

Anything comes to your mind?

Jason it's a fact...

I did the same with the image, copied it to the reports folder, edited the xml source to just read the name of the image (logoBMX.jpg instead of the path WebContent/Images/logoBMX.jpg) and it shows just fine in the PDF.

I can live with that but it really bothers me why I can't use a path to have a neat and organized resource folder...

Do you mind if we try to solve the path problem to reach the resources in a neat way?

BTW I tried this on Tomcat and set my resource folder like:

config.setResourcePath(sc.getRealPath("/lib"));

where sc was the servlet context. I created a lib directory in my web
app put my image in it and it worked fine. This is not in the designer
but deployed.

Hey Jason.

I'll try that in Tomcat first then take it to Weblogic. I guess that paths and contexts differ so much between application servers.

Thanks for your help. I'll keep you posted with that.

Dan.

PS: I sent you my Skype ID as you requested. I'll try not to bother you with it and keep the thread alive to help someone else with the same problems.

Could you post the string that translates this:

Thanks man.

Jason no luck at all in any case.

When deployed the RealPath is:

C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\WebReport\Images

And when executed from within Eclipse the RealPath is:

D:\PROJECTS\OPQ\Reports\ServletExample\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\WebReport\Images

Both paths lead to folders where the image exists...

Can't figure out what is wrong and why is it so difficult to point to a resource.... Where did you locate your lib folder? Can you post your real path?

Dan,

I am not certain what is happening: In the report design the image
should just be the name, no path. In the preferences in the designer
you can set the resource folder to whatever you want. When deployed you
can set it with the code posted earlier. Mine looks like this when
deployed.

C:\apps\apache-tomcat-5.5.20\webapps\WebReport\lib

The issue is solved. Jason help me out and I'm gonna post what we did so anyone can benefit from it Cool

First, set the resources path in Windows-> Preferences->Report Design-> Resource. There will be a button that reads "Workspace" and make it lead to the folder where you have your images. It should be a folder that once you deploy your WebApp in is at the top level of your WAR file.

I pointed that path to:

${workspace_loc:WebReport/WebContent/Images}

That's an expression that is automatically generated once you choose your resources (images) folder. I chose that since that Images folder is deployed at top level when the WAR is generated.

The next step is to tell your engine that you want that path as your resources path.

You do just that simply in a line:

config.setResourcePath( Formats.getPath("/Images", sc) );

Where config is an instance of "EngineConfig" and "Formats" is a class where I have a routine that successfully finds the path regardless of your App Server:

public static synchronized String getPath(String path, ServletContext sc) {
		String realPath = "";
		
		realPath = sc.getRealPath(path);
		
		if (realPath == null) {
			try {
				realPath = sc.getResource(path).getPath();
			} catch (MalformedURLException e) {
				e.printStackTrace();
			}
		}
		
		return realPath;
	}

That way I was able to display an image from a shared resource.

Note that your XML source of your report should have a reference to your image without anything before its name like the following:

        <image id="23">
            <property name="height">0.5625in</property>
            <property name="width">2.5416666666666665in</property>
            <property name="source">file</property>
            <expression name="uri" type="constant">logoBMX.jpg</expression>
        </image>

Hope you find this helpful as I did.

Best of regards,
Dan
