I am trying to save a simple template to pdf using the rendering plugin, but I cannot get it to work no matter what I try. All I need is for it to save a file within the file system on the server and redirect to a different page.
At the minute the pdf template does not need any parameters as it just prints hello world. Once I get this working I will attempt to add some data.
I am getting errors saying I need to specify a controller if no '/' is appended. But I have tried adding this to no avail. Plus I don't understand which controller it needs as I have tried specifying the controller this action is declared.
Can someone please have a look at this and tell me what I'm doing wrong?
RenderingService pdfRenderingService
def displayPDFSummary = {
ByteArrayOutputStream bytes = pdfRenderingService.render(template: "_pdfTemplate", controller:"RSSCustomerOrder", model: [origSessionId:params.origSessionId])
def fos= new FileOutputStream('NewTestFile.pdf')
fos.write(bytes)
fos.close()
render(template: "_pdfTemplate", params: [origSessionId:params.origSessionId])
}
I am getting the following error messages in the console:
groovy.lang.MissingMethodException: No signature of method: java.io.FileOutputStream.write() is applicable for argument types: (java.io.ByteArrayOutputStream)
(Then prints contents of template...)
Possible solutions: write([B), write(int), write([B), write(int), wait(), wait(long)
Did you look at the FileOutputStream docs? There's no write(OutputStream) method.
Try fos.write(bytes.toByteArray()). Also, bytes.writeTo(fos) may work.

------------ORIGINAL QUESTION------------------
In my Splash Script, I am trying to use "splash:go" on a new url that is based on the "src" attribute of an "img" tag. How can I access this "src" relative url and join it to a start_url?
For example, imagine that the img element has the following contents:
<img id="ImageViewer1_docImage" onload="BlockerResize('ImageViewer1_ContentBlocker1','ImageViewer1_WaterMarkImage');" src="ACSResource.axd?SCTTYPE=ENCRYPTED&SCTKEY=gMYed5OWqcT9I1Y2fM85DvB48X5U1DQ5mOUiJoUH4rioyau0nJdxt0PHFfGVTMiUsork/YD+Cw0F6ZzcviP4sG09xrqWM8/zJlyEeVRFkKXVnkyHYWgwNJzCSUE4Kh4yCsqw6mCuIxWxPj6BAI7Hbw==&CNTWIDTH=849&CNTHEIGHT=684&FITTYPE=Height&ZOOM=1" alt="Please wait" style="border-width:0px;cursor: url(images/Cursors/hmove.cur); z-index: 1000">
Here I am trying to extract the src attribute and add it to start_url:
https://i2a.uslandrecords.com/ME/Cumberland/D/
I want all of this inside the Splash script. I need it to be done inside of Splash because otherwise I lose my security/encryption or something--it renders "Bad Data" instead of the new webpage. Do you have any recommendations?
------------UPDATE------------------
So I managed to obtain the url I needed from the src attribute using the following code:
var = splash:evaljs("document.getElementById('ImageViewer1_docImage').src;")
splash:go(var)
However, the problem is that this is producing a error message. All I find in the snapshot is a white page with the following message:
Failed loading page (Frame load interrupted by policy change)
https://i2a.uslandrecords.com/ME/Cumberland/D/ACSResource.axd?SCTTYPE=ENCRYPTED&SCTKEY=gMYed5OWqcSvEWOJA6wGVmb642s2oZHqkYmT6VTpORTzMY7CgvDU5jsjJG/xp0X3eQ9BiDnbaTdAmISeLkC3hyjxGjcSnXOKgGDa8cI2fniY0ILT+NqvQToMGIB+/X3ZIs7Q+D4ppTSZGYZ2L4M/
Webkit error #102
Any idea why?
The image src attribute is exactly the URL you need to access or as stated by the question title you need to append it to some other URL parts?
If that is the case, you can do it by '..'
Ex.: splash:go(base_url..var) -- concatenation
ISSUE RESOLVED:
Here is the solution. The GET request was breaking down because it didn't know how to render the image in html given the webkit settings. If you execute the GET request without rendering the page, the response.body has the image.
CODE:
local response = splash:http_get(var)
return {
body = response.body
}
I am developing Rails 4 application where have to modify existing PDF file.
User can write some comments and click then comments write in existing PDF as well. For this, i used gem 'pdf-toolkit'
But i got below error:

My Code:
my_pdf = PDF::Toolkit.open("Credit_One.pdf")
my_pdf.updated_at = Time.now # ModDate
my_pdf["SomeAttribute"] = "Some value"
my_pdf.save!
Where is wrong any one have a idea.
Thanks
I'm designing a jasper report using iReport which takes a parameter and fetches an image from a given URL:
The parameter is a user's screen name in twitter, and the url is it's profile image.
<image>
<reportElement x="4" y="51" width="73" height="64"/>
<imageExpression><![CDATA["https://api.twitter.com/1/users/profile_image?screen_name="+$F{user_screen_name}+"&size=bigger"]]></imageExpression>
</image>
It works great when the image exists. If it doesn't the following exception is thrown:

Print not filled. Try to use an EmptyDataSource...
How can i handle this situation in the jrxml file?
I would like to simply add a fixed URL address in case it can't find one.
Anyone has any suggestions?
Thank you!
I think you need to add an additional helper class to handle this. You need a static method boolean urlExists(String url) that would allow you to put this in the imageExpression:
MyClass.urlExists($F{image_url}) ? $F{image_url} : $P{fallback_image}
It would be a simple class to write... but clearly there's additional complexity in adding in another .jar file. Without that method, I can't see any way to do the processing in the .jrxml.
in jrxml file,
to show image from url resource, use image expression URL()
like below, for example $F{ADPN_NO} is parameter from report
<imageExpression><![CDATA[new URL("http://anyserver:7001/images/"+$F{ADPN_NO}+".jpg")]]></imageExpression>
when onError occurred, it will show blank item, icon, or error that is set on jrxml.
the other way, outside of jrxml file, you can use java map object which contains img urls that is check by URL() or File() Exception ..
In my case I had a report to which I "injected" the image's url and it was causing an error with the certificate (the url I was "injecting" had the IP and it had to be a name for the certificate). After I changed the url it worked.
I get this exception for a seemingly valid URL:
document = componentLoader.loadComponentFromURL(templateURL, "_blank", FrameSearchFlag.CREATE, new PropertyValue[0]);
Called with templateURL being:
file:///var/lib/tomcat6/webapps/convert/WEB-INF/template.odp
BTW: the same code runs well on windows. (Of course diff URL is generated).
Edit: For URLs like:
private:factory/simpress
I get the same error.
You get this error message when the corresponding application (Calc, Writer etc.) is not installed in your system.
I originally tried to install the (Debian) metapackage openoffice.org-headless which did not contain any of the individual programs, only the core infrastructure.
I am using Grails 1.3.5, SQL Server 2005, iReports 3.7.6, Jasper Plugin 1.1.3. In my GSP page I have given the jasperReprt tag as:
<g:jasperReport jasper="report1" format="PDF">
<input type="hidden" name="test_id" id="test_id"/>
<input type="hidden" name="order_no" id="order_no" />
</g:jasperReport>
For development, in Config.groovy I have specified the
jasper.dir.reports = './reports'
There are two files created in the reports folder when a new report is created and saved, i.e. report.jrxml and report.jasper.
When clicked on the PDF icon in IE or Firefox, an 500 server error is thrown and below is stack trace.
[2010-11-27 01:13:14.998] ERROR groovy.grails.web.errors.GrailsExceptionResolver Invalid byte 1 of 1-byte UTF-8 sequence.

But if I delete the report1.jasper, the error is no longer thrown when PDF icon is clicked and the PDF report is shown fine.
Is this the correct way to do it?
My second issue is with using Sub Reports. Sub report is in the same folder as the main report. But When the report is executed from the application, below error is thrown:
[2010-11-27 01:30:27.556] ERROR groovy.grails.web.errors.GrailsExceptionResolver Could not load object from location : ./reports\report1sub_report.jasper
net.sf.jasperreports.engine.JRException: Could not load object from location : ./reports\urine_routinepatient_details_sub_report.jasper

at net.sf.jasperreports.engine.fill.JRFillSubreport.evaluateSubreport(JRFillSubreport.java:327)
It does not find the sub report. How can I fix it?
Thank you.
Jay Chandran.
Edit:
I have been searching during this whole time, but still could not find a proper solution. So I did some trial and error. I figured out that, deleting report1.jasper and just leaving jasper.jrxml in the report directory works just fine as I said earlier.
For the sub-report issue: It was giving error Could not load object from location : ./reports\report1sub_report.jasper For some strange reason, the main report name report was getting appended to the name sub_report.jasper and was looking for a file named report1sub_report.jasper
So I created a sub-folder under reports folder and named it report1 and updated report1.jrxml file
<subreportExpression class="java.lang.String"><![CDATA[$P{SUBREPORT_DIR} + "\\sub_report.jasper"]]></subreportExpression>
I had to add the extra \\ slash even though the "SUBREPORT_DIR" parameter had \\ the slashes at the end of the path as shown below.
<parameter name="SUBREPORT_DIR" class="java.lang.String" isForPrompting="false">
<defaultValueExpression><![CDATA["F:\\Workspace\\SpringSource2.5.0\\GrailsProjec\\reports\\report1\\"]]></defaultValueExpression>
</parameter>
Notice the \\ at the end. I don't know why it was not getting appended!
Another way would have been to just change the sub-report name from sub_report.jasper
to report1sub_report.jasper!!! :)
I have tested this in production mode and it works fine. I am not sure if this is the way to do it, but all other possible solutions did not work for me.
Feedback will be very helpful.
I assume you have a version conflict here. iReport stores JRXML files and seems to compile them automatically to .jasper. The Grails Jasper plugin picks up the compile variant and gets into trouble with it. So try to disable compiled output in ireport.
The Grails Jasper plugin 1.1.3 uses internally Jasper 3.7.4, the used ireport is 3.7.6.
Regarding the sub reports: no idea.
The MalformedByteSequenceException is caused by a character encoding conflict. I'd suggest to use UTF-8 instead of Windows' Win-1252 (similar to ISO-8859-1) everywhere.
In Jasper's etc/ireport.conf file, change the default_options to:
default_options="-J-Dfile.encoding=UTF-8 -J-Xms24m -J-Xmx64m"
(Where Xms and Xmx are unrelated memory settings. If there are default settings with that config entry, you can overtake them, else, just leave them out.)
See this forum thread for alternative configurations.
As for the error with subreports, take a look at the backslash \ that's probably wrong.
EDIT : There is some information about two issues which maybe could help in
http://grails.org/plugin/jasper#faqTab
i hope i can help with one of the issues: which one related with subreports dir.
The problem is the plugin code sets SUBREPORT_DIR to the complete file path of main report, including its name. However the code honour the user provided param with the same name, so if you fill this param with whatever value except null the plugin will use it.
For example if you chain directly the jasper controller you can do:
def renderAs(data,format) {
def reportParams=params.clone()
reportParams["_format"]=reportParams["_format"]?:"${format.toUpperCase()}"
reportParams["SUBREPORT_DIR"]=CH.config.jasper.dir.reports+"/"
chain(controller:'jasper',action:'index',model:[data:[]+data],params:reportParams)
}
In your scenario an (ugly) option would be create an hidden input with name SUBREPORT_DIR and value the desired one. I would fill the paremeter in other way.
EDIT:
Another annoying problem is where do we have to put the main reports and compiled subreports:
When you run the app with run-app they work if you put them all in a folder with the same name as CH.config.jasper.dir.reports(reportDir) in the root of the grails app.
But if you want to deploy a war you have to put the main reports in a folder reportDir in the root of war file and compiled subreports in WEB-INF/classes/reportDir.
I've opted to keep all files in grailsApp/reports and copy the resources in the appropiate folders in the war grails task. In my BuildConfig.groovy i've added (reportDir is "reports"):
grails.war.resources = { stagingDir,args ->
def classpathDir="${stagingDir}/WEB-INF/classes"
copy(toDir:"${stagingDir}/reports") {
fileset(dir:"reports",includes:"**")
}
copy(toDir:"${classpathDir}/reports") {
fileset(dir:"reports",excludes:"**.jrxml")
}
}
Hope it helps.
