Relative path to call a subreport?

2003-05-07 06:45

Hi.

 

It is a way to enter a relative path for a sub report.

 

For the moment I use an absolute path:

 

Example:

 

In the folder c:Projectspropertiesxmlreports I have the 2 following files:

Statements.xml (master report) and statementOfAccount.jasper (sub report).

 

In the statements.xml file I have

 

<connectionExpression>$P{REPORT_CONNECTION}</connectionExpression>

<subreportExpression class="java.lang.String"><![CDATA["C:\Projects\properties\xml\reports\statementOfAccount.jasper"]]></subreportExpression>

 

I try this modification:

 

<connectionExpression>$P{REPORT_CONNECTION}</connectionExpression>

<subreportExpression class="java.lang.String"><![CDATA["statementOfAccount.jasper"]]></subreportExpression>

 

The system didnÂ’t found the statementOfAccount.jasper file. For the images the relative path works.

 

Thanks

 

Simon

Objects as subreports are loaded using a class called JRLoader.

 

This class try to convert your string in a URL, if it fails, it try to use it as an absolute path (ore relative path to the application), if fails, invoke a class loader to load it as a resource.

 

The solution is: add you print objects directory to the classpath and try again.

 

Let me know.

Thanks for your help.

 

For the moment, I can't use a URL path to load the file, may be later...

 

In JRLoader class, in the method loadObjectFromLocation (String location)

 

When you create a new File (String), if you didn't enter the path of the file, but only his name, the application will try to find the file in the current folder.

 

Do you known what could be the current classpath of tomcat. I will try to modify the current folder of tomcat.

 

I don’t known if it is a good id饅

Personally, I habe modified the file startup.bat of Tomcat adding at the begin of the file this lines...

 

set JAVA_HOME=C:j2sdk1.4.0_01

set CLASSPATH=C:mywebapplicationpathWEB-INFCLASSES

Hi,

 

When I put a absolute path in the xml file, it will be in the jasper file.

 

So if in my sub report I got one absolute path. I can't move the jasper file to another folder.

 

So my question is: What is the best way to move the report of one environment to another ( development env to staging...)

 

Probably the response will be the ULR path?

 

Thanks

 

Simon

In my application I load a properties file for my servlet. In this file is specified the absolute path of report. I pass it as parameter to jasperreports.
