Jasper reports error in weblogic 8.1

Hello,

I'm using jasperreports 3.6.0 in weblogic 8.1. When I try to compile a report I'm getting:

net.sf.jasperreports.engine.JRRuntimeException: Error creating SAX parser

Does anyone know how to solve this issue? Thanks.

That property does not seem to be recognized by your version of sax. Which one are you using ? Did you try "http://java.sun.com/xml/properties/jaxp/schemaLanguage"

I use xerces 1.4.4. But i don't know how to change the property.

This link should be useful -> http://xerces.apache.org/xerces2-j/properties.html

I believe this is done in the back by weblogic (probably a conflict in the libs, since the jasper version is very new and xerces one is very old, yet i'm not able to find the correct jasper version for xerces 1.4.4). This is how my controller looks like:

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		
		boolean b  = compileReport(request);
		System.out.println(b);
		
		
		ReportBean bean = new ReportBean();
		try {
			BeanUtils.populate(bean, request.getParameterMap());
		} catch (Exception e) {
			e.printStackTrace();
		}

if (b) {
			
			try {
				viewReport(request, response);
				
			} catch (Exception e) {
				e.printStackTrace();
			}
		}
		
		
		
	}
	
	private void fillReport() {
		try {
			System.out.println("Filling the report");
			Map<String, ReportBean> map = new HashMap<String, ReportBean>();
			ArrayList<ReportBean> list = createRandomList();
			
			JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(list);
			
			JasperFillManager.fillReportToFile("reports\\example.jasper", map, ds);
			System.out.println("Done");
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
	
	private boolean compileReport(HttpServletRequest request) {
		System.out.println("preparing to compile");
		try {
			System.out.println("Compiling report...");
			System.out.println(request.getContextPath());
			JasperCompileManager.compileReportToFile("reports\\example.jrxml");
			
			System.out.println("Done");
		} catch (JRException jre) {
			jre.printStackTrace();
			return false;
		}
		return true;
	}
	
	private void viewReport(HttpServletRequest request, HttpServletResponse response) throws Exception {
		System.out.println("creating response");
		
		ArrayList<ReportBean> list = createRandomList();
		
		JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(list);
		String param = JasperRunManager.runReportToHtmlFile("reports\\example.jasper", new HashMap(), ds);
		System.out.println("Done");
		request.setAttribute("report", param);
		request.getRequestDispatcher("reports/example.html").forward(request, response);
		
	}

This works on tomcat 6 and jboss 5. So it must be a jar conflict (or more). I don't know if the link you gave me helps in this matter because i don't see where I should insert the code.

New error, after trying with jasper 2.0.5:

net.sf.jasperreports.engine.JRException: No report compiler set for language : null
at net.sf.jasperreports.engine.JasperCompileManager.getCompiler(JasperCompileManager.java:508)
at net.sf.jasperreports.engine.JasperCompileManager.compileReport(JasperCompileManager.java:219)
at net.sf.jasperreports.engine.JasperCompileManager.compileReportToFile(JasperCompileManager.java:135)
at net.sf.jasperreports.engine.JasperCompileManager.compileReportToFile(JasperCompileManager.java:94)

What's this?

That error seems to be Jasper specific. Google churned up a few links when I searched. Here is one

http://jasperforge.org/plugins/espforum/view.php?group_id=112&forumid=102&topicid=47369

I have a new error now. I'm trying to compile the jrxml in the servlet but i'm getting a filenotfoundexception:

my servlet uri is http://localhost:8080/tests/report.jsp

i have the file in tests/reports.

JasperCompileManager.compileReportToFile("reports/example.jrxml");

i've tried in different ways, with full server path, replacing / with \\, etc yet it doesn't find it. So how to i put the path to the file relative to the server? if i hardcode it (C:\\server\\....) it finds it...

Nevermind, i got it

Thanks for the help

I am glad that you solved the problem. Can you share your solution with us so that others will also benefit from it ? Thanks

Sure, here it is:
JasperCompileManager.compileReportToFile(getServletContext().getRealPath("/jsp/example.jrxml"));

my jrxml was in the application on the server/jsp

Thank you
