<p>During an Ant build of Metacat, you will see many HttpServletRequest, HttpServletResponse and
|
|
54
|
other errors. The compiler will complain that it cannot find a symbol, for example:</p>
|
|
55
|
<div class="code">
|
|
56
|
[javac] /home/daigle/workspace/metacat/build/src/edu/ucsb/nceas/metacat/MetaCatServlet.java:506: cannot find symbol<br>
|
|
57
|
[javac] symbol : class HttpServletResponse<br>
|
|
58
|
[javac] location: class edu.ucsb.nceas.metacat.MetaCatServlet<br>
|
|
59
|
[javac] HttpServletResponse response) throws ServletException, IOException {<br>
|
|
60
|
[javac] ^<br>
|
|
61
|
</div>
|
|
62
|
|
|
63
|
<p>This is usually caused by the build not being able to find native Tomcat libraries. edit your
|
|
64
|
build.properties file in
|
|
65
|
|
|
66
|
<a name="InstallationIssues"></a><div class="header1">Installation Issues</div>
|
|
67
|
|
|
68
|
<a name="StartupIssues"></a><div class="header1">Startup Issues</div>
|
|
69
|
<a name="Jdk14Logger"></a><div class="header2">Metacat doesn't start and Jdk14Logger exception</div>
|
|
70
|
<p>The symptoms are that the metacat service will not show up at all, even though Tomcat
|
|
71
|
is serving, and the following error shows up in the tomcat log (catalina.log):</p>
|
|
72
|
|
|
73
|
<div class="code">org.apache.commons.logging.LogConfigurationException: User-specified log
|
|
74
|
class 'org.apache.commons.logging.impl.Jdk14Logger' cannot be found or is
|
|
75
|
not useable </div>
|
|
76
|
|
|
77
|
<p>This message typically occurs in the tomcat log (catalina.log)
|
|
78
|
when Tomcat has been installed on an Ubuntu/Debian system using apt-get install.
|
|
79
|
And the application is started using:
|
|
80
|
|
|
81
|
<div class="code">/etc/init.d/tomcat6 start</div>
|
|
82
|
|
|
83
|
<p>The problem is that the standard startup scripts reference the
|
|
84
|
common java service, jsvc. Metacat will not run under jsvc. The solutions are:
|
|
85
|
<ul>
|
|
86
|
<li>Download the <a href="http://knb.ecoinformatics.org/software/download.html">Metacat binary install package</a>
|
|
87
|
and replace your /etc/init.d/tomcat6 startup script with the one provided in the
|
|
88
|
package.</li>
|
|
89
|
<li>Run Tomcat from the Tomcat binary directory: <tomcat_home>/bin/startup.sh and
|
|
90
|
<tomcat_home>/bin/shutdown.sh</li>
|
|
91
|
</ul>
|
|
92
|

<a name="ConfigurationIssues"></a><div class="header1">Configuration Issues</div>
|
|
94
|
<a name="DbUpdateIssue"></a><div class="header2">Database Update Fails (not a connectivity issue)</div>
|
|
95
|
<p>There are a number of reasons why the database update utility might fail during
|
|
96
|
configuration. You will need to determine if the error returned indicates a connectivity issue
|
|
97
|
or some issue with the database schema/data. If it is the latter, the first step in
|
|
98
|
troubleshooting the issue is to run the db scripts manually and analyze the output.</p>
|
|
99
|
|
|
100
|
<p>The configuration utility will report which scripts it tried to run. To
|
|
101
|
run these scripts, refer to
|
|
102
|
<a href="../user/run-db-scripts.html">how to run database scripts</a></p>
|
|
103
|
|
|
104
|
<p>If the answer is not obvious, further troubleshooting may require a database
|
|
105
|
administrator.</p>

|
|
108
|
<a name="MapDisplayIssue"></a><div class="header2">Maps will not display</div>
|
|
109
|
<p>There are two known reasons why maps might not display in a web browser.</p>
|
|
110
|
<ul>
|
|
111
|
<li>Sarfari Browser - the safari browser is not supported by the map libraries. You will
|
|
112
|
need to switch to a different browser.</li>
|
|
113
|
<li>Firefox Browser with the Firebug plugin - Firebug is a plugin that allows a developer
|
|
114
|
to easily view and troubleshoot web page layouts. Unfortunately, this plugin can
|
|
115
|
keep the maps from displaying. There is no plan by the third party map display
|
|
116
|
developers to address this issue. You will need to disable Firebug in your
|
|
117
|
browser.</li>
|
|
118
|
</ul>

<a name="503ServiceTemporarilyUnavailable"></a><div class="header2">Mutliple Tests Fail : 503 Service Temporarily Unavailable</div>
|
|
122
|
<p>When running "ant test", multiple tests fail. The output files have the error: </p>
|
|
123
|
<div class="code">503 Service Temporarily Unavailable</div>
|
|
124
|
<p>This typically means your Metacat server is not running.</p>
