Calling Ant from a JSP Page (2)
First thanks for all the responses the first time!
What I'm trying to do:
Call Ant from a JSP page. I created a JSP page that runs on Tomcat, with an
HTML text link that calls a Servlet with the following code:
try {
PrintWriter out = res.getWriter();
out.write("step 1"); // debug
Process p = Runtime.getRuntime().exec("c:\\ant\\bin\\ant.bat -buildfile
c:\\ant\\bin\\build.xml -logfile c:\\ant\\bin\\foo.txt");
out.write("step 2"); // debug
out.flush();
out.print("<html><head><META HTTP-EQUIV='Refresh'
CONTENT='0;URL=http://localhost:8080/foo.jsp?QProjName=foobar></head><body><
/body></html>");
out.close(); <?xml:namespace prefix = o ns =
"urn:schemas-microsoft-com:office:office" />
} catch (IOException ex){
throw new ServletException("IOException: " +
ex.toString())
}
The output of the page is "step 1setp 2". There are NO errors that I could
find-checked Java Console, Tomcat DOS window, all logs in
<tomcat_home>\logs. My guess is the output is causing problems. Can someone
suggest an easy want to encapsulate the output for ease of debugging?
The build.xml files calls Windows Command.com to execute a source safe batch
file. The batch file opens a project and gets (saves to local drive) all the
files from the project.
I can successfully run the string in the .exec(minus the extra '\''s) from
Run or an MS-DOS box.
Could someone suggest a cleaner way of doing this?
Will there be an ANT API?
Thanks!

Ew. Why not just call org.apache.tools.ant.Main() directly?

There already is an Ant API!!!!
Download the source, and accompanying javadocs.
