[net.sf.jasperreports.engine.JRRuntimeException: Increment class not found. error]

I had the same error and your fix worked for me as well.

[Why does my report preview not work when I use an Integer array parameter?]

I've opened issue #3910 for this problem.

[Why does my report preview not work when I use an Integer array parameter?]

It seems I have the same problem with any array type. I set the value and the preview never generates.

[Why does my report preview not work when I use an Integer array parameter?]

I have a report with an Integer[] parameter set to prompt and I keep getting this message even though I am setting the parameter:

 

"The report requires that you specify the value for some parameters before running it."

 

I'm new to Jaspersoft Studio so maybe I am missing something simple.

[java.lang.StackOverflowError]

Was there ever a resolution for this issue? I'm experiencing the same stack trace.

[java.lang.StackOverflowError]

This problem has returned for me as well. Very difficult to consistently reproduce. I'm running Jasper through a WAR and JAR inside an EAR file for deployment. I have the log4j.properties file in /WEB-INF/classes inside my WAR file and /lib in my EAR file. And I am still experiencing this issue. toffer, are you experiencing this issue anymore? How are you deploying Jasper?

[Still getting StackOverflowErrror after applying fix]

I have applied the fix described here:  http://community.jaspersoft.com/questions/535452/javalangstackoverflowerror

to work around the StackOverflowError when a subreport spans more than 1 page in a main report. I have a report with multiple subreports and this error is being thrown again. Are there any limitations on how many subreports can be in a report? Is there something else I can change?

[Which Jasper jars are required in my application?]

Maybe I'm forgetting but what does POC stand for?

By the way the reason I ask is that I believe the versions of xalan and xerces included with JasperReports are out of sync with each other. In addition to that as of Java 1.6 Xerces is now part of the JRE.

[Which Jasper jars are required in my application?]

The binary release of JasperReports includes a /lib directory with a lot of jar files in it. Which ones should I include in my application?

[Subreport with images and text]

Have you tried setting "Position Type" to "Float" on the text below the image?

[write expressio for if else condition?]

What are the types of those fields?

[java.lang.StackOverflowError]

I've just run into this problem today so it still exists. I was able to use the workaround. How I did it was to create a

log4j.properties

file that includes this property:

log4j.logger.org.apache.commons.javaflow=info

Then I packaged it inside my war (I'm using a web application) under /WEB-INF/classes.

Has the real issue behind this error been discovered? I'm looking at putting JasperReports into production at my company but I'm very concerned about this.

[How can I use a value from subreport in "Print When" expression]

Looks like my issue is related to this bug: http://jasperforge.org/plugins/mantis/view.php?id=3260

[How can I use a value from subreport in "Print When" expression]

I have a detail band I don't want printed unless 1 of the 4 subreports inside of it returns a non-null value. But it seems that when I try using the variables that receive these values from the subreports in the "Print When" expression of the main report it doesn't work. They are always null during the expression evaluation.

How can I do this?

[Initializing a null return value from a subreport]

I have an Integer being returned from a subreport. In both the main report and subreport I have the Initial Value Expression of the variables set to 0. However when no data is found in the subreport the value printed is always "null". Is there a property I can set to have this value be 0 when null?

[What is the class I should use to evaulte default expressions for parameters? [SOLVED]]

 I figured it out. The class is:

net.sf.jasperreports.engine.fill.JRParameterDefaultValuesEvaluator

[What is the class I should use to evaulte default expressions for parameters? [SOLVED]]

I'm looking for a way to get the default values of parameters in a report. I've seen several evaluator classes in the 4.0.1 API but the only one I see that has a public constructor is

net.sf.jasperreports.components.table.fill.BuiltinExpressionEvaluatorDecorator

But I have no idea what those arguments in the constructor should be and it's not documented. Can anyone point me in the right direction?

[Using java.io.InputStream as a parameter]

Although I'm not sure if I understand correctly what I am doing, checking the Using Cache option of the subreport allows this to work correctly...I think.

[Using java.io.InputStream as a parameter]

I have a subreport with the class set to InputStream and the expression set to parameter X. When I set X with the expression:

 

new FileInputStream("subreport.jasper")

 

I get a java.io.EOFException. If I take the same expression from parameter X and place it directly in the subreport expression it works. What am I doing wrong here?

[Need help using method as a parameter to find a subreport]

The background of this problem is that I have a web application reading report files from a predefined location. The reports, and their subreports, will be stored in jar files. I don't know if this is the best approach but it's the first one I chose. The only way I know of to get at a file inside a jar is by accessing it as an InputStream so that's what I've chosen as the subreport expression type in iReport.

Inside iReport I'm looking for a way to hardcode the name of the subreport but make the class and method it is supplied to a parameter. This allows me to run it both in iReport and from the web app.

Is there a good way to do this or am I barking up the wrong tree?

[Loading ttf font files located on the filesystem]

Sorry to resurrect this after so long but I'm working on this again. Although I did resolve the classloader issues I was having I'm still not sure how to get jasper to "see" the other fonts on the system. From what I understand you're saying I have the option of packaging fonts or relying on the operating system to provide them. How would I go about configuring the latter case?

[Loading ttf font files located on the filesystem]

Not only have I done that but I have tried adding them to the jasperreports-fonts jar. The problem is I keep running into this classloader problem with Oracle Application Server  (see other thread). That's why I was wondering if I could somehow just make the *ttf files available to the OS. This particular machine is Red Hat AS.

By the way what are the standard fonts? Just those already available on the OS?

[Loading ttf font files located on the filesystem]

I was wondering about packages that already exist like msttfcorefonts and how they interact with Jasper. I'm not a font expert so that's why I'm asking.

[Class loader issues with subreports and OAS]

I'm getting a Class Not Found exception for one of the font jars I've created when I use it in a subreport. As long as it's not in a subreport I'm ok. I'm running on Oracle Application Server 10.1.2.3.0 (jdk 1.4.2.)

I noticed a similar issue here but there's no mention of subreports or a resolution. Has anyone else encountered something like this or know how I can solve it?

[Loading ttf font files located on the filesystem]

I've looked at some of the font threads here about loading ttf files through extension jars but how about loading *.tff files that already exist on a linux filesystem in a non-standard location? What are the options for loading/reading ttf files at runtime?
